    Full Text Available Background: The prevalence of setariasis in cattle and cerebrospinal nematodiasis in sheep and goats were determined in two geographical regions of Iran.Methods: In two provinces of Iran: Mazandaran (zone I and Qazvine (zoneII   where sheep and goats were suffering from symptoms similar to cerebrospinal nematodiasis, the peritoneal cavities of  763 and 1020 cattle were searched for adult Setaria sp. respectively. History taking of 4770 sheep from zone I and 25550 sheep and 3190 goats from zone II were per­formed for the presence and determination of cerebrospinal nematodiasis in sheep and goats. To study pathological changes induced in central nervous system 7 sheep from zone I and 4 sheep and 2 goats from zone II with symptoms similar to CSN were necropsied.Results: Our findings revealed that 47% and 13.2% of cattle in zone I and II harboured Setaria digitata (99.45% and S. digitata (67.12% plus S.labiato-papillosa (17.46% respectively. History taking showed that each year 2.53% of sheep in zone I and 1.65% of sheep and 1.25% of goats in some districts of zone II (e.g. Roudbar Alamout  suffered from symp­toms similar to cerebrospinal nematodiasis the main clinical signs of which were difficulty in hind limbs movement (lumbar paralysis. At necropsy, no lesions were observed macroscopically in the brains as well as spinal cords. But in a few cases, central nervous system were congested  and edematous .Histopathological examination of CNS of necropsied animals showed mild leptomeningitis and eosinophilic and lymphacytic encephalomyelitis with numerous hemorrhagic tracts, degeneration and necrosis due to migration of the larvae. The cross section of nematode larvae was observed in the brain section of a sheep in zone I. Conclusion: The results of this study showed that setariasis of cattle is very prevalent in both region mainly in zone I and sheep and goats harbor low percentage of CSN but with marked pathological lesions.

  3. ELISA to study antibody responses to anthrax vaccine in cattle, sheep and goats

    International Nuclear Information System (INIS)

    An ELISA based on tri-partite toxin partially purified from Bacillus anthracis was used to determine the antibody responses of groups of cattle, sheep and goats after anthrax vaccination. All species produced detectable increases in antibody titres after vaccination with the order being cattle>sheep>goats. A second vaccination induced variable anamnestic responses depending on the species or time (6 or 22 weeks) after the primary dose. Large differences were observed between individual animals with respect to the antibody induced by the 2 vaccine doses. This observation, together with differences in vaccine quality and apparent immunogenicity may affect efficient control of anthrax outbreaks. ELISA provided a convenient method of determining the relative contribution of these factors to the protection afforded by anthrax vaccination programs. (author). 10 refs, 3 figs, 2 tabs

  5. Seasonal changes in water content and turnover in cattle, sheep and goats grazing under humid tropical conditions in Ghana

    International Nuclear Information System (INIS)

    The effect of seasonal changes on water content and water turnover of cattle, sheep and goats at pasture under humid tropical conditions was studied. Measurement of total body water and water turnover was based on the tritium dilution technique. Total body water was significantly higher in all three species of animal during the dry season, while water turnover was significantly lower in the dry season than in the wet season. In all seasons water turnover was highest in cattle, followed by sheep and then goat. Changes in body weight, body water, body solids and water turnover were associated with seasonal variations in nutrition. The indication was that the goat would be a more suitable animal for production under dry conditions than cattle and sheep. (author)

    The objective of the study was to update energy and protein requirements of growing sheep, goats and cattle in warm areas through a meta-analysis study of 590 publications. Requirements were expressed on metabolic live weight (MLW=LW0.75) and LW1 basis. The maintenance requirements for energy were 542.64 and 631.26 kJ ME/kg LW0.75 for small ruminants and cattle, respectively, and the difference was significant (Prequirement for 1 g gain was 24.3 kJ ME without any significant effect of species. Relative to LW0.75, there was no difference among genotypes intra-species in terms of ME requirement for maintenance and gain. However, small ruminants of warm and tropical climate appeared to have higher ME requirements for maintenance relative to live weight (LW) compared with temperate climate ones and cattle. Maintenance requirements for protein were estimated via two approaches. For these two methods, the data in which retained nitrogen (RN) was used cover the same range of variability of observations. The regression of digestible CP intake (DCPI, g/kg LW0.75) against RN (g/kg LW0.75) indicated that DCP requirements are significantly higher in sheep (3.36 g/kg LW0.75) than in goats (2.38 g/kg LW0.75), with cattle intermediate (2.81 g/kg LW0.75), without any significant difference in the quantity of DCPI/g retained CP (RCP) (40.43). Regressing metabolisable protein (MP) or minimal digestible protein in the intestine (PDImin) against RCP showed that there was no difference between species and genotypes, neither for the intercept (maintenance=3.51 g/kg LW0.75 for sheep and goat v. 4.35 for cattle) nor for the slope (growth=0.60 g MP/g RCP). The regression of DCP against ADG showed that DCP requirements did not differ among species or genotypes. These new feeding standards are derived from a wider range of nutritional conditions compared with existing feeding standards as they are based on a larger database. The standards seem to be more appropriate for ruminants in warm and

    Capripoxviruses are the cause of sheeppox, goatpox and lumpy skin disease (LSD) of cattle. These diseases are of great economic significance to farmers in regions in which they are endemic and are a major constraint to international trade in livestock and their products. Although the distribution of capripoxviruses is considerably reduced from what it was even 50 years ago, they are now expanding their territory, with recent outbreaks of sheeppox or goatpox in Vietnam, Mongolia and Greece, and outbreaks of LSD in Ethiopia, Egypt and Israel. Increased legal and illegal trade in live animals provides the potential for further spread, with, for instance, the possibility of LSD becoming firmly established in Asia. This review briefly summarizes what is known about capripoxviruses, including their impact on livestock production, their geographic range, host-specificity, clinical disease, transmission and genomics, and considers current developments in diagnostic tests and vaccines. Capripoxviruses have the potential to become emerging disease threats because of global climate change and changes in patterns of trade in animals and animal products. They also could be used as economic bioterrorism agents. PMID:18774991

    The present study describes the prevalence of Peste-des-petits-ruminant virus (PPRV) antibodies in cattle, buffaloes, sheep and goats carried out during the period 2011 using the serum samples randomly collected from different villages of five states of India. A total of 1,498 serum samples [n = 605 (cattle); n = 432 (buffaloes); n = 173 (sheep); n = 288 (goats)] were collected from 52 districts in five states (Andhra Pradesh, Gujarat, Jammu and Kashmir, Maharashtra and Rajasthan) of India and were screened for PPRV-specific antibodies by using PPR monoclonal antibody-based competitive ELISA kit. Analysis of 1,498 samples indicates that an overall seroprevalence of 21.83 % with 11.07 % in cattle, 16.20 % in buffaloes, 45.66 % in sheep and 38.54 % in goats. This report presents the results of PPRV-specific antibodies in situations where the subclinical, inapparent or nonlethal or recovery of infection was suspected in cattle, buffaloes, sheep and goats. The presence of PPRV antibodies demonstrate that bovines are exposed to PPRV infection and it implies the importance of cattle and buffaloes as subclinical hosts for the virus besides widespread presence of the disease in sheep and goats. Further, the study showed that the prevalence of PPRV antibodies in apparently healthy livestock under natural situation, 21.83 % of the animals were protected from PPRV re-infection. This inturn help in the implementation of disease control strategies such as vaccination in that particular geographical area. PMID:24426314

  10. Surveillance of Rift Valley fever in cattle, goats and sheep in Uganda

    International Nuclear Information System (INIS)

    Increasing occurrence of outbreaks of Rift Valley fever (RVF) has been witnessed in southern Somalia, north-eastern Kenya and northern Tanzania during heavy and prolonged, often unseasonal, rainfall since 1997-98. More recently epizootics were reported in Kenya, Somalia, Tanzania, Sudan, Madagascar and South Africa. Because Uganda is located in the endemic zone of RVF, surveillance was conducted to enable early detection of outbreaks. Testing of frozen and fresh bovine sera retrospectively from 1997 to 2008 using IgM ELISA revealed a seroprevalence ranging from 0 to 2.5%, while VNT revealed 9.65% prevalence. Testing of goat and sheep samples collected from 2005 to 2008 through a cross-sectional study targeting commercial farms and free-range flocks in flood-prone zones in Uganda revealed a seroprevalence ranging from 5.3-27.9% and 0-0.9% by IgG ELISA and IgM ELISA, respectively. Virus neutralization test revealed 32.3% prevalence among goat flocks from these same places. Although indigenous breeds of cattle, goats and sheep, known to be less susceptible to RVF than exotic breeds (Anon., 2005), are predominant in areas surveyed, it is likely that the RVF virus is circulating in livestock in some of these locations. Outbreaks are likely to occur once favourable conditions are met. Studies to establish the distribution of RVF vector mosquitoes and the proportion of susceptible hosts in areas with high sero-prevalence are required to further elucidate the status of RVF in Uganda

    Full Text Available Aim: To estimate the prevalence and distribution of serum antibodies to BTV in different domesticated animals in different localities of Saudi Arabia. Materials and Methods: A total of 4845 field sera collected from different animal species within 10 districts in the Kingdom of Saudi Arabia were screened for the presence of group-specific BTV antibodies by competitive ELISA (c ELISA. Results: The overall BTV antibody prevalence was 54.1%, 53.3%, 44.8% and 25.7% in sheep, goat, cattle and camel respectively (at 95% confidence level. The Jizan and Eastern Province districts were the regions with the highest prevalence resulting 65.8% of sheep, 68.2% of goats, 49.3% of cattle, 44% of camel in Jizan and 65.8% of sheep, 62.5% of goats, 53.4% of cattle, 28.5% of camel in Eastern Province positive to c-ELISA. The second highest rate was in Najran district where the seropositivity for Bluetongue was found to be 60% of sheep, 57.9% of goats, 47.2% of cattle and 29.3% of camel. Our results recorded positive animals in all examined districts which indicate serological evidence of exposure to infection was widely distributed all over the country. Conclusions: These results demonstrate the high occurrence of the BTV that emphasize the necessity to a well-defined control strategy for preventing and controlling the BTV in Saudi Arabia. [Vet.

    This work is an example of cooperation between veterinary and human medicine being fully complementary and at the same time, indispensable to improve our knowledge on animal chlamydiosis. This study investigated the existence of ocular chlamydiae and determined the prevalence of its presence, chlamydiosis, in asymptomatic and diseased farm animals and adjacent humans. Data were obtained by the omp2 gene family Chlamydiaceae-specific PCR. Two hundred cattle, buffaloes, sheep and goats and 44 human specimens were also examined. Conjunctival swabs from both the eyes were collected from all animals and humans using cotton swabs. Samples were tested for chlamydiae by Vero cells tissue culture, chicken embryo, modified Gimenez staining, direct fluorescein-conjugated monoclonal antibody staining (FA), immunoperoxidase, CFT and PCR. The PCR-RFLP revealed that Chlamydophila psittaci demonstrated in the conjunctival samples of cattle (68% asymptomatic and 88% diseased), of buffalo (68% asymptomatic and 72% diseased), of sheep (68% asymptomatic and 80% diseased), of goat (76% asymptomatic and 92% diseased) and of humans (77% asymptomatic and 82% diseased). The Cp. psittaci was the only chlamydiae demonstrated in all of the ocular conjunctival samples, which confirms the prevalence of Cp. psittaci in this population of animals and adjacent humans. Statistically, the animal species factor was calculated and was found to be of no significance. Yet, there appeared to be a significant difference in the percentage of animal that tested positive using the different methods. Detection of Cp. psittaci in most samples confirms the prevalence of Cp. psittaci in this population of animals and adjacent humans. PMID:22584046

  16. Collaborative study on the detection of antibodies against peste des petits ruminants virus in cattle, sheep and goats and the possible implications to rinderpest control programmes

    International Nuclear Information System (INIS)

    Monoclonal antibody-based competitive ELISA (C-ELISA) have been used for the specific measurement of antibodies to both rinderpest and peste des petits ruminants (PPR) viruses in cattle, sheep and goats. Examination of serum samples from sheep and goats in Gambia, before and after vaccination with rinderpest vaccine, suggested that antibodies to PPR virus could prevent an immune response to the rinderpest vaccine. Cattle sera from nigeria and Ghana showed a high prevalence of antibody against PPR virus which may explain the difficulty experienced in some countries in achieving high post-vaccination immunity levels against rinderpest. This is further supported by experiments in Nigeria where a high percentage of cattle sero-positive for PPR failed to respond serologically following rinderpest vaccination. Because antibodies against PPR virus are both cross-neutralizing and cross-protective against rinderpest virus further vaccination in the presence of antibodies against PPR virus may be a waste of national resources. This paper presents serological evidence for the transmission of PPR virus from sheep and goats to cattle and highlights the need to include PPR serology in the sero-monitoring programme to give a better indication of national herd immunity in PPR endemic areas where problems of reaching high immunity without obvious cause are being encountered.

    Escherichia coli O157:H7 and Salmonella are significant foodborne pathogens that can be found in the feces and on the hides of meat animals. When hides are removed during the harvest process, the carcass and subsequent meat products can become contaminated. Camels, cattle, sheep, and goats are harvested for meat in Riyadh, Saudi Arabia. The prevalence of E. coli O157:H7 and Salmonella are unknown in these animals, and it is assumed that if the animals carry the pathogens in their feces or on their hides, meat products are likely to become contaminated. To this end, a minimum of 206 samples each from hides and feces of camels, cattle, goats, and sheep were collected over the course of 8 months and tested for E. coli O157:H7 and Salmonella. It was found that E. coli O157:H7 was present in feces (10.7, 1.4, 2.4, and 2.4%) and on hides (17.9, 8.2, 2.9, and 9.2%) of cattle, goats, camels, and sheep, respectively. The prevalence of Salmonella was 11.2, 13.5, 23.2, and 18.8% in feces and 80.2, 51.2 67.6, and 60.2% on hides of cattle, goats, camels, and sheep, respectively. The prevalence of E coli O157:H7 was nearly zero in all samples collected in June and July, while Salmonella did not exhibit any seasonal variation. These results constitute the first comprehensive study of E. coli O157:H7 and Salmonella prevalence in Saudi Arabian meat animals at harvest. PMID:25581182

  19. Short chain fatty acids in the forestomach of camels and indigenous cattle, sheep and goats and in the caecum of donkeys grazing a thornbush savannah pasture

    International Nuclear Information System (INIS)

    Concentrations of short chain fatty acids (SCFAs) were measured in the forestomach of camels and indigenous cattle, sheep and goats and in the caecum of donkeys grazing a thornbush savannah pasture. Total SCFA concentrations in camels were 40-90% higher than in ruminants. SCFA concentrations in the caecum of donkeys were about 30-40% lower. Seasonal variations in the quality of feed and differences in the feeding behaviour of the five animal species indicate considerable differences of microbial activity in the fermentation chambers. Concentrations of SCFAs in the fermentation chambers, on the other hand, showed only small seasonal variations; no differences between sheep and goats were found, although goats selected a diet of significantly higher digestibility in the dry season than sheep. The absorption of SCFAs through the epithelium of the reticulorumen of sheep and goats measured in the temporarily isolated forestomach was similar in the two species. The rate constants of SCFA absorption were 60-90% higher for propionate and butyrate than for acetate. Parallel measurements of forestomach fluid volumes and fluid turnover showed larger SCFA pools and higher flow rates of SCFAs (relative to body weight) in camels than in the ruminants. It is concluded that concentrations of SCFAs do not reflect actual SCFA production rates. Dilution rate, rumen fluid volume and absorption rate influence SCFA concentrations far more than production rate. (author). 20 refs, 3 figs, 6 tabs

    Wool production oriented sheep keeping is the most important rural activity in Patagonia, Argentina, followed by goat and at a lower extent cattle production. The existing perception on the smallholder production systems from most decision makers (e.g., policy) is that they are marginal, with low productivity and have negative returns. Since the Argentinean economic scenario has changed drastically in the last decade, the aim of this study was to analyze the economic and productive contribution of different livestock species in smallholdings. The results showed that the post-1990's economic scenario turned most smallholder livestock systems to have positive economic performance, but there were still productive restrictions that limited to fully benefit from these favorable circumstances. Goats were the most profitable livestock due to their higher productive performance, followed by sheep and cattle, with poorer performances. A strong cooperation between the intervention programs and research institutions is recommended to overcome the current production bottlenecks, by focusing on cattle and sheep production systems.

    The main goal of this study was to develop a comparative multi-colour Zoo-FISH on domestic ruminants metaphases using a combination of whole chromosome and sub-chromosomal painting probes obtained from the river buffalo species (Bubalus bubalis, 2n = 50,XY). A total of 13 DNA probes were obtained through chromosome microdissection and DOP-PCR amplification, labelled with two fluorochromes and sequentially hybridized on river buffalo, cattle (Bos taurus, 2n = 60,XY), sheep (Ovis aries, 2n = 54,XY) and goat (Capra hircus, 2n = 60,XY) metaphases. The same set of paintings were then hybridized on bovine secondary oocytes to test their potential use for aneuploidy detection during in vitro maturation. FISH showed excellent specificity on metaphases and interphase nuclei of all the investigated species. Eight pairs of chromosomes were simultaneously identified in buffalo, whereas the same set of probes covered 13 out 30 chromosome pairs in the bovine and goat karyotypes and 40% of the sheep karyotype (11 out of 27 chromosome pairs). This result allowed development of the first comparative M-FISH karyotype within the domestic ruminants. The molecular resolution of complex karyotypes by FISH is particularly useful for the small chromosomes, whose similarity in the banding patterns makes their identification very difficult. The M-FISH karyotype also represents a practical tool for structural and numerical chromosome abnormalities diagnosis. In this regard, the successful hybridization on bovine secondary oocytes confirmed the potential use of this set of probes for the simultaneous identification on the same germ cell of 12 chromosome aneuploidies. This is a fundamental result for monitoring the reproductive health of the domestic animals in relation to management errors and/or environmental hazards. PMID:25330006

    This study was designed to compare the sperm nuclear morphometric subpopulations of four species of domestic artiodactyls (cattle, sheep, goat and pigs). Samples from 20 males of each species were collected. After semen collection, sperm concentration and motility were measured and samples prepared for morphometric determinations. Smears were fixed with 2% glutaraldehyde, stained with Hoechst 33342 and photographed. At least 200 spermatozoa per sample were processed using the Image J analysis open software. Clustering procedures were performed to identify sperm subpopulations using the morphometric data obtained from each species. Results of the present study show that, applying the computer-assisted sperm morphometry analyisis-fluorescence (CASMA-F) technology and multivariate cluster analyses, it was possible to determine the subpopulations of spermatozoa with different morphometric characteristics in the four species studied. Bulls and boars had two clearly differentiated size categories: large and small. However, the final sperm subpopulations were four in the bull (large-round, large-elongated, small-round, and small-elongated) and only three in the boar (large, small-elongated and small-round). In small ruminant species, three sperm nuclei size categories were established: large, average sized and small. Two of these subpopulations were also elongated in goat bucks, with three subpopulations (large-round, small-elongated and average size-elongated). In the ram three morphometric subpopulations were also obtained (large, small and average size-round), but none was elongated. When comparing among species, sperm subpopulations were smaller in the buck and less elliptical and elongated in the ram than those in the other species studied. Male variability was identified in the distribution of sperm subpopulations described in the four species studied. It was concluded that the combination of CASMA-F technology with multivariate cluster analyses allow the study of

    Paratuberculosis is a chronic insidious, often serious, disease of the global small ruminant industries, mainly causing losses from mortalities and reduced productivity on-farm, interference in trading and, in Australia, profound socio-economic impacts that have periodically compromised harmony of rural communities. The pathogenesis, diagnosis, impacts and disease management options for ovine and caprine paratuberculosis are reviewed, comparing current controls in the extensive management system for sheep in wool flocks in Australia with the semi-intensive system of dairy flocks/herds in Greece. Improved understanding of the immune and cellular profiles of sheep with varying paratuberculosis outcomes and the recognition of the need for prolonged vaccination and biosecurity is considered of relevance to future control strategies. Paratuberculosis in goats is also of global distribution although the prevalence, economic impact and strategic control options are less well recognized, possibly due to the relatively meagre resources available for goat industry research. Although there have been some recent advances, more work is required on developing control strategies for goats, particularly in dairy situations where there is an important need for validation of improved diagnostic assays and the recognition of the potential impacts for vaccination. For all species, a research priority remains the identification of tests that can detect latent and subclinical infections to enhance removal of future sources of infectious material from flocks/herds and the food chain, plus predict the likely outcomes of animals exposed to the organism at an early age. Improving national paratuberculosis control programs should also be a priority to manage disease risk from trade. The importance of strong leadership and communication, building trust within rural communities confused by the difficulties in managing this insidious disease, reflects the importance of change management

    Q fever is an almost ubiquitous zoonosis caused by Coxiella burnetii, which is able to infect several animal species, as well as humans. Cattle, sheep and goats are the primary animal reservoirs. In small ruminants, infections are mostly without clinical symptoms, however, abortions and stillbirths can occur, mainly during late pregnancy. Shedding of C. burnetii occurs in feces, milk and, mostly, in placental membranes and birth fluids. During parturition of infected small ruminants, bacteria from birth products become aerosolized. Transmission to humans mainly happens through inhalation of contaminated aerosols. In the last decade, there have been several, sometimes large, human Q fever outbreaks related to sheep and goats. In this review, we describe C. burnetii infections in sheep and goats, including both advantages and disadvantages of available laboratory techniques, as pathology, different serological tests, PCR and culture to detect C. burnetii. Moreover, worldwide prevalences of C. burnetii in small ruminants are described, as well as possibilities for treatment and prevention. Prevention of shedding and subsequent environmental contamination by vaccination of sheep and goats with a phase I vaccine are possible. In addition, compulsory surveillance of C. burnetii in small ruminant farms raises awareness and hygiene measures in farms help to decrease exposure of people to the organism. Finally, this review challenges how to contain an infection of C. burnetii in small ruminants, bearing in mind possible consequences for the human population and probable interference of veterinary strategies, human risk perception and political considerations.

    Full Text Available Leptospirosis and brucellosis are common zoonosis that affect many species of mammals mostly causing economical losses. Further, very important fact is huge danger for human and animal health around the world. The purpose of the study is to determine the prevalence of Brucella spp. and Leptospira spp. using multiplex polymerase chain reaction (mPCR method, in blood samples collected from cattle, sheep and goats. In this study, a total number of 250 blood samples (5 cc of blood with ethilen diamin tetra asetic acid were collected randomly from 100 cattle, 80 sheep and 70 goats located on 6 herds in Chaharmahal Va Bakhtiari and Esfahan provinces, Iran. After DNA extraction and setting of mPCR for Brucella spp. and Leptospira spp. mPCR products were screened. The DNA of these microorganisms was detected by multiplex PCR from 31 and 21 out of 100 cattle, respectively. Four of 70 goat’s blood samples from goat breeding farms were positive for Leptospira spp. and 11 were positive for Brucella spp. Out of 80 sheep blood samples 23 were positive for Brucella spp. and 14 for Leptospira spp. The results of the present study show ruminant as an important reservoir for transmission of these zoonotic diseases to humans in Iran. mPCR has the ability to concurrently detect both Brucella and Leptospira species from blood samples of ruminants. The convenience and the possibility of detection of both bacteria at a time, strongly support the use of this mPCR for routine diagnostics.

This disease is zoonosis and widely distributed in many districts of Java and as a zoonotic disease. Cat is the definitive host of T. gondii, while sheep, goats, and humans are the intermediate hosts. The prevalence of toxoplasmosis in Java was between 7 to 84%, with an average of 42.9%. It occurs through out of the year and causes abortions and infertilities of infected animals. All bre...

  10. Live monitoring of cattle, reindeer and sheep

    International Nuclear Information System (INIS)

    After the Chernobyl accident the fallout differed considerably from area to area in Norway and specially were found from soil samples that the mountain pasture in Middle and South of Norway were heavily contaminated. These natural ecosystem is important in several nutrition pathways; notably sheep, goat, reindeer and cattle. In June 1986 the Health Directorate imposed action levels for the nuclides Cs-134 and Cs-137. The action levels were 370 Bq/kg for milk and baby food and 600 Bq/kg for all other types of food. In November 1986, the action level for reindeer meat were increased to 6000 Bq/kg, and in June 1987 the level was also increased to 6000 Bq/kg for wild freshwater fish. The most effected meat production were reindeer, sheep and cattle. Almost 20 to 35% of the sheep had activity levels above the action limits. This fact initiated a broad program to establish effective measure to increase the activity levels and to sort out the animals which could be slaughtered. Three main approaches have been utilized in Norway in order to achieve this and to limit the potential health risk: action aimed at reducing uptake from soil to vegetation (plowing, use of fertilizing etc.); action aimed at reducing uptake from fodder to animals (use of cesium binder, change of slaughter time), or reducing unacceptable activity levels in animals (downfeeding); action aimed at reducing intake to human (interdiction, dietary advice). Live monitoring were in several of these actions necessary for a successful result

  12. Use of ionizing radiation in the development of vaccines against Fasciola gigantica and Schistosoma bovis in Sudanese cattle, sheep and goats

    International Nuclear Information System (INIS)

    A primary infection with Fasciola gigantica, which had been eliminated by anthelmintic treatment after eight weeks, stimulated partial resistance to homologous challenge in calves and goats. Similar sensitization with F. gigantica or Schistosoma bovis also stimulated significant resistance to heterologous challenge in calves. The level of resistance was indicated by reduced fluke recoveries from sensitized animals compared with controls, by lower values of the enzymes sorbitol dehydrogenase and glutamate dehydrogenase, indicating less hepatic damage, and by lower blood indices, indicating more severe anaemia. Infection of calves with metacercariae of F. gigantica irradiated at 30 Gy or 200 Gy resulted in mean fluke recoveries of 75 and 41 respectively, whereas 332 flukes were recovered from controls infected with non-irradiated metacercariae. The flukes recovered from animals infected with irradiated metacercariae were stunted and resided in the small bile ductules. Sensitization for eight weeks with metacercariae of F. gigantica irradiated at 30 Gy resulted in significant resistance in calves, sheep and goats to homologous challenge. Significant resistance was also stimulated in calves by sensitization for eight weeks with metacercariae of F. gigantica irradiated at 200 Gy. However, sensitization for four weeks with F. gigantica irradiated at 30 Gy failed to stimulate significant resistance in calves to homologous challenge, but similar sensitization, twice at an interval of four weeks, resulted in an average reduction of 62% in fluke recovery from calves with homologous challenge. This reduction was, however, statistically insignificant. Moreover, sensitization for eight weeks with cercariae of Schistosoma bovis irradiated at 30 Gy did not stimulate heterologous resistance in calves or goats to F. gigantica. A similar result was also obtained after sensitization of calves for 36 weeks with cercariae of S. bovis irradiated at 30 Gy before challenge with F

  15. Adaptation of indigenous sheep, goats and camels in harsh grazing conditions

    International Nuclear Information System (INIS)

    Microbial breakdown of cellulose is a rather slow process. Therefore the retention time of digesta and the volume of the fermentation chamber are factors limiting the quantity of fibrous diets that can be digested. Indigenous ruminants can generally adapt to harsh grazing conditions better than conventional breeds. Unexpectedly high rumen volumes were reported in a number of indigenous ruminants. In studies reported in this paper, Heidschnucken, an indigenous breed of sheep in the heather region of Northern Germany, were able to increase their rumen volume from 14% to 22% of body weight during adaptation to a low quality fibrous diet. Heidschnucken did not lose significant body weight, whereas Blackface sheep lost 20% and failed to adapt the rumen volume. Rumen volume of indigenous sheep and goats in Northern Kenya was 20% of body weight while grazing in the thornbush savannah during the dry season, compared with 9-12% while kept indoors on a hay-concentrate diet. Mean retention time of particles in the total gastrointestinal tract of goats and sheep in Kenya was 38 h and 46 h respectively. In the experiment with Heidschnucken, these sheep increased the retention time of particles to 71 h on a straw diet, while Blackface sheep retained particles 58 h. Dietary preference and feed intake have been studied in indigenous sheep and goats in Kenya at seasonal pasture conditions in the thornbush savannah. Goats have a higher preference to dicotyledon species (92-97%) than sheep, who are less selective grazers. The feeding behaviour of indigenous sheep and goats was complementary rather than competitive. Feeding observations indicate that this is also the case when cattle (grazers) and camels (browsers) are included in such a comparison. (author)

  16. Survey on coenurosis in sheep and goats in Egypt

    2011-09-01

    Full Text Available A total of 75 sheep and goats from apparently healthy and from clinically affected flocks were examined for Coenurus cerebralis cysts from different localities in Egypt. Of 25 animals examined from clinically diseased sheep and goats, 25 (100% revealed the presence of infestation with one to four coenuri in the brain. The sites of predilection were the left hemisphere (48%, followed by the right hemisphere (40% and the cerebellum (12%. There was no apparent effect of the age of sheep and goats on susceptibility to infestation with C. cerebralis. Another 50 animals from apparently healthy sheep and goat herds presented no C. cerebralis cysts. The cysts from infested sheep could infest newborn puppies experimentally, with a prepatent period of 60 days post infestation. A total of 15 immature worms that were recovered from one puppy did not reach patency until 105 days post infestation with C. cerebralis cyst scolices. Pathological changes in C. cerebralis-infested sheep brain revealed parasitic elements, demyelinated nerve tracts, hyperaemic blood vessels with round cell infiltration, encephalomalacia with round cell infiltration and palisading macrophages and giant cells, as well as focal replacement of the brain parenchyma with caseated and calcified materials. The morphological characteristics of both the larval stage from sheep and goats and adult worms of Taenia multiceps from experimentally infested dogs are described. The results conclude that C. cerebralis is one of the principal causes of nervous manifestations of coenurosis in clinically diseased sheep and goats in Egypt.

  17. Forage selection by teddy goats versus sheep on thal ranges

    International Nuclear Information System (INIS)

    Grazing behaviours of Teddy goats and Thalli sheep were studied on rangelands of ThaI. Bite count method was used to determine the dietary composition of both animal species. The overall preference of Teddy goats was higher for Khabble grass (Cynodon dactylon), which was 40.57% of the total number of bite made on different plant species during the study period (March-July). Teddy goats utilized a wide range of browsing plant species like Wan (Salvadora oleoides), Phog (Calligonum polygonoides), Babil (Acacia jacquemontii), Jandi (Prosopis spicigera) etc. Browsing species were major component (>50%) of goat diets dur- ing March through June. Whereas Thalli sheep had been consistent in their heavy use of Khabble grass (overall 89.27%). Browsing plant species were not an important component of their diets. Teddy goats and Thalli sheep were competitive for Khabble grass particularly at its vegetative growth stage. (author)

    2015-12-14

    Orf virus, a member of the genus Parapoxvirus, is the causative agent of contagious ecthyma ('Orf'). It is a pathogen with worldwide distribution, causing significant financial losses in livestock production. The disease mainly affects sheep and goats, but various other ruminants and mammals have been reported to be infected as well. It is also a zoonotic disease, affecting mainly people who come in direct or indirect contact with infected animals (e.g. farmers, veterinarians). The disease is usually benign and self-limiting, although in many cases, especially in young animals, it can be persistent and even fatal. Production losses caused by Orf virus are believed to be underestimated, as it is not a notifiable disease. This review of literature presents all latest information regarding the virus; considerations regarding treatment and prevention will be also discussed. PMID:26315771

  1. Seroprevalence and potential risk factors for Brucella spp. infection in traditional cattle, sheep and goats reared in urban, periurban and rural areas of Niger.

    Directory of Open Access Journals (Sweden)

    Abdou Razac Boukary

    Full Text Available INTRODUCTION: In Niamey, Niger, interactions within the interface between animals, humans and the environment induce a potential risk of brucellosis transmission between animals and from animals to humans. Currently, little is known about the transmission of Brucella in this context. RESULTS: 5,192 animals from 681 herds were included in the study. Serum samples and hygroma fluids were collected. A household survey enabled to identify the risk factors for transmission of brucellosis. The true adjusted herd-level prevalence of brucellosis ranged between 11.2% and 17.2% and the true adjusted animal-population level prevalence was 1.3% (95% CI: 0.9-1.8% based on indirect ELISA test for Brucella antibodies. Animals aged of 1-4 years were found to be more susceptible than animals less than 1 year old (Odds ratio [OR] of 2.7; 95% CI: 1.43-5.28. For cattle, the odds of brucellosis seropositivity were higher in rural compared to the periurban areas (OR of 2.8; 95% CI: 1.48-5.17 whereas for small ruminants the risk of seropositivity appeared to be higher in urban compared to periurban areas (OR of 5.5; 95% CI: 1.48-20.38. At herd level, the risk of transmission was increased by transhumance (OR of 5.4; 95% CI: 2.84-10.41, the occurrence of abortions (OR of 3.0; 95% CI: 1.40-6.41, and for herds having more than 50 animals (OR of 11.0; 95% CI: 3.75-32.46. Brucella abortus biovar 3 was isolated from the hygromas. CONCLUSION: brucellosis in Niger is a serious problem among cattle especially in the rural areas around Niamey and among sheep in the urban areas of Niamey. The seroprevalence varies across strata and animal species with important risk factors including herd size, abortion and transhumance at herd level and age at animal population level. For effective control of brucellosis, an integrated approach seems appropriate involving all stakeholders working in public and animal health.

    Full Text Available Helminths cause great economic loss in livestock in Africa, and can be categorized as either direct or indirect losses. Arid and semi-arid lands (ASAL in Kenya comprise 71 % of total land area and harbour the largest population of cattle, sheep and goats. However, little information on the distribution and impact of gastro-intestinal (GIT parasitism in these animals is available. This survey was conducted to establish the prevalence of GIT parasites infecting calves, sheep and goats and their relative importance in Magadi division, which is semi-arid. Faecal samples were obtained directly from the rectum of 109 calves, 133 goats and 20 sheep and submitted to the laboratory for faecal worm egg counts, and coccidial oocysts examination using a modified McMaster method. The significance of differences in mean egg count per gram (epg between animal species and herds (farms were assessed using analysis of variance. The overall prevalence of nematodes in the calves, sheep and goats was 69.2 %, 80 % and 82 %, respectively. About 10 % of sheep and goats had epgs higher than 1 000, the remainder having light to moderate infections. The overall prevalence of coccidial oocysts in calves, sheep and goats was 30 %, 44 % and 45 %, respectively. Poor productivity in ASAL areas, where nutrition is often poor, is likely to be pronounced in the presence of parasite infections. These findings indicate that viable internal parasite control should be implemented in the study area in order to increase the productivity of the livestock there.

  5. Factors of welfare reduction in dairy sheep and goats

    2010-01-01

    Full Text Available Scientific research on factors causing the reduction of well-being in sheep and goats is rather recent, as are studies of strategies to minimize the adverse effects of environmental challenges and improper management practices on flock welfare. Sheep and goats, considered very rustic animals, are reared prevalently under extensive production systems and are widespread mainly in marginal areas. For these reasons, only few studies on the welfare of these species have been carried out in the past. More recently, the scenario has changed, due to a gradual diffusion of intensive and semi-intensive production systems, especially in dairy sheep and goat breeds, to the growing concern of consumers about the life conditions of farmed animals, and to the issuing of a number of rules and laws on the safety of animal products and well-being of farmed livestock. As a consequence, several research groups have turned their attention to the welfare of sheep and goats. Nevertheless, information on this topic is still scarce. This paper reviews major critical points regarding the endangerment of welfare in farmed sheep and goats. Climatic extremes and seasonal fluctuations in herbage amount and quality are discussed as important causes of the reduction of well-being in extensive production systems, which can impair production efficiency of grazing animals and dramatically affect the welfare and health status of sheep and goats. Space allowance and structures of sheep and goat houses are described as the main potential sources of discomfort for housed flocks, together with inadequate control of micro-environment, and inappropriate milking procedures and human-animal interactions. Recent studies on the impact of high ambient temperature, different ventilation regimes, high stocking densities, reduced airspace and poor litter management on behaviour, immune and endocrine response, and on performance of sheep and goats are discussed.

    Full Text Available Kinetics of long-acting oxytetracycline (OTC injected intravenously (IV at a dose of 5 mg/kg was determined in each of eight camels, sheep and goats. The disposition of OTC was described by two-compartment open model. Two elimination half-lives were recorded for the camel (81 min and 46.1 h, whereas in sheep and goats these were 3.2 and 3.4 h, respectively. The peak plasma concentration was 10.2, 850 and 780 g/ml at 5 minutes in camel, sheep and goats, respectively. The values of volume of distribution were 1.4, 13.4 and 12.1 litre/kg for the camels, sheep and goats, respectively. In sheep and goats, values of t1/2, Vd and clearance were found similar but different from camel, indicating exclusive distribution and substantial storage which were consistent with oxytetracycline lipophilicity and the large fat content of camel body.

Results: Out of total 1293 animal serum samples (sheep-1028 and goats-265, 17.5% of sheep and 14.7% of goats serum samples were found positive. The overall prevalence of anti-BT antibodies in different governorates was 16.9%. The highest prevalence of bluetongue group specific antibodies was detected in Beni-Suef, Giza, and Al Sharqia governorates (13.2%. The results indicate that there is a necessity to run further studies to identify the negative governorates. In addition, there is a lack in information regarding the BTV serotypes in Egypt. Conclusion: This study reflected high seroprevalence of bluetongue infection in sheep than goats. The results indicated that further studies are needed to identify the vectors from different agro-climatic zones, in addition, the BTV serotypes that are circulating in Egypt.

    The embryo transfer techniques used in small ruminants worldwide are based in surgical procedures. These actions are performed under general anesthesia which needs a combination of animal fasting and drugs for secure animal handling and surgery manipulations. Therefore, it involves risks to animal health and life. The major limiting sequels are adhesions formed by the abdominal surgery, in the ovaries, uterus, or between them. These occurrences can both compromise uterus accessing and oocyte capture and are responsible for decreasing success and limiting successive embryo collections. In contrast, nonsurgical embryo procedures can be performed in a relatively simplified way. Nonsurgical embryo recovery does not need animal prolonged starvation, drug retention is minimized, and donors can stay in a standing position. After the end of embryo recovery, donors are promptly restored to their routine housing and feeding. Furthermore, this technique does not need incisions and, therefore, can be used repetitively in superovulated or nonsuperovulated goats and sheep for embryo recovery-a similar procedure done in cattle. In Brazil, promising results are reported using nonsurgical embryo transfer in recipient goats, and studies are currently evaluating similar procedures in sheep. Therefore, this review aimed to present the current panorama of nonsurgical embryo transfer in sheep and goats. PMID:27177961

    2001-12-01

    Small ruminants play an important role in the epidemiology and transmission of Foot-and-Mouth Disease (FMD). The main reasons therefore are: FMD is difficult to diagnose as infected sheep not always show typical clinical symptoms or as the cardinal signs mimicked other diseases. Sheep and goats may be carriers. Infected herds which practice transhumance or are nomadic can spread the infection to other herds long before diagnose of the disease is established. Shipping and trade with live sheep and goats is much more common world wide than in other FMD susceptible species. Lack of registration of all sheep and goat herds (especially of small hobby herds) and lack of individual identifications signs (ear tags) may result in incomplete control measurements under FMD conditions. Basing on published experiences with the actual FMD epidemic in the UK and basing on the own experiences with the restrictions to prevent from spreading of the FMD from the UK to Germany suggestions for future disease control are made.

  16. Protozoan infections (Toxoplasma gondii, Neospora caninum and Sarcocystis spp.) in sheep and goats: recent advances.

    Science.gov (United States)

    Buxton, D

    1998-01-01

    The protozoan parasite Toxoplasma gondii is a serious cause of fetal mortality in sheep and goats. Oocysts, the parasite stage responsible for initiating infection, are produced following a primary infection in cats. A primary infection in pregnant sheep and goats can establish a placental and fetal infection which may result in fetal death and resorption, abortion or stillbirth. Diagnosis is aided by the clinical picture, the presence of characteristic small white necrotic foci in placental cotyledons, the possible presence of a mummified fetus and on fetal serology and histopathology. Development of the polymerase chain reaction (PCR) specific for T. gondii may also provide a valuable diagnostic tool. Measures to control abortion include improved management of farm cats, fodder and water. Vaccination of sheep with the live vaccine is an effective preventive measure and the use of decoquinate in feed may be useful in some situations. Neospora caninum is related to T. gondii and while its asexual life cycle is similar to that of the latter it is currently not known whether it has a similar sexual life cycle in a definitive host. Neospora is an important cause of fetal loss in cattle and parallels that of T. gondii infection in sheep and goats. While it does not appear to cause frequent losses in these latter animals, experimental infection is readily induced in them and if initiated during pregnancy provides a very good model of the bovine infection. Furthermore clinical signs and pathological lesions in sheep and goats are similar to those induced in them by T. gondii, although there are subtle histopathological differences. These changes will aid possible diagnosis as will specific serological tests such as the indirect immunofluorescent antibody test and the enzyme linked immunosorbent assay and the PCR. Sarcocystis, which exists as numerous species, undergoes a coccidian-like life cycle with each having a distinctive definitive (usually carnivore) host which

    Full Text Available The aim of this study was to determine the prevalence of exposure to the zoonotic abortifacients Brucella spp, Coxiella burnetii and Chlamydophila abortus among sheep and goats in the Caribbean Tri-Island state of Grenada. Documentation of exposure to these important bacterial pathogens will facilitate instituting appropriate prevention and control measures. Serum samples were collected from 582 animals from the islands of Grenada and Carriacou during 2009-2010. Sera were tested by enzyme-linked immunosorbent assay (ELISA for determination of antibodies to smooth lipopolysaccharides (s-LPS of B. abortus strain S-99, inactivated C. abortus antigens and to C. burnetii phase I and II purified antigens. None of the animals examined tested positive for antibody to C. burnetii. Evidence of Brucella exposure was noted in 13 (3.6% of 362 sheep, representing animals from both islands of Grenada and Carriacou, whereas none of the 220 goats examined tested positive. Exposure to either Brucella abortus or B. melitensis could account for the detected antibody to Brucella s-LPS antigens. Antibody to C. abortus was detected in 6.0% of animals tested (24 sheep and 10 goats, representing animals from Carriacou and all 6 parishes of Grenada. Taken together, our results indicate moderate widespread exposure of small ruminants to the zoonotic abortifacients Brucella spp and Chlamydophila abortus in the tri-island state of Grenada and is the first report documenting such exposures in any animal species in this region of the Caribbean.

  20. Diagnosis of Clostridium perfringens intestinal infections in sheep and goats.

    Science.gov (United States)

    Uzal, Francisco A; Songer, J Glenn

    2008-05-01

    Clostridium perfringens produces enteric diseases, generically called enterotoxemias, in sheep, goats, and other animals. This microorganism can be a normal inhabitant of the intestine of most animal species, including humans, but when the intestinal environment is altered by sudden changes in diet or other factors, C. perfringens proliferates and produces potent toxins that act locally or are absorbed into the general circulation with usually devastating effects on the host. History, clinical signs, and gross postmortem findings are useful tools for establishing a presumptive diagnosis of clostridial enterotoxemia in sheep and goats. Definitive diagnosis requires laboratory confirmation. Isolation of some types of C. perfringens (e.g., B and C) can be of diagnostic value, but other types (e.g., A) are so commonly found in the intestine of normal animals that isolation is meaningless from a diagnostic point of view. The most accepted criterion in establishing a definitive diagnosis of enterotoxemia is detection of C. perfringens toxins in intestinal contents. Also, histopathological examination of brain is very useful for diagnosis of type D disease, as lesions produced by epsilon toxin in the brains of sheep and goats are pathognomonic for type D enterotoxemia. Ancillary tests, such as measuring urine glucose or observing Gram-stained smears of intestinal mucosa, can be used. However, although such tests have a presumptive diagnostic value when positive, they cannot be used to rule out a diagnosis of enterotoxemia when negative. PMID:18460610

  1. Marker-assisted selection in sheep and goats

    International Nuclear Information System (INIS)

    Sheep and goats are often kept in low input production systems, often at subsistence levels. In such systems, the uptake of effective commercial breeding programmes is limited, let alone the uptake of more advanced technologies such as those needed for marker-assisted selection (MAS). However, effective breeding programmes exist in a number of countries, the largest ones in Australia and New Zealand aiming for genetic improvement of meat and wool characteristics as well as disease resistance and fecundity. Advances have been made in sheep gene mapping with the marker map consisting of more than 1 200 microsatellites, and a virtual genome sequence together with a very dense single nucleotide polymorphism (SNP) map are expected within a year. Significant research efforts into quantitative trait loci (QTL) are under way and a number of commercial sheep gene tests have already become available, mainly for single gene effects but some for muscularity and disease resistance. Gene mapping in goats is much less advanced with mainly some activity in dairy goats. Integration of genotypic information into commercial genetic evaluation and optimal selection strategies is a challenge that deserves more development. (author)

About 198,729 farmers are raising sheep and goats and the average farm size is about 16 heads. The sheep and goat livestock declined by 34 % in the analyzed period accounting for 10,058 thousand heads in 2009. Sheep/goat ratio changed from 14/1 in 1990 to 9.96/1 in 2009, in the advantage of goats. Sheep and goats are mainly grown in Central, North-Eastern and South-Western Romania. Mutton and goat meat production accounted for 1,443 thousand tons in 2009, being by 40 % lower than in 1990  because of  livestock  decline.  About 23 % mutton and sheep meat is produced in the South-Eastern Romania, 18 % in the Central part and 14 % in North-East. The share of mutton and goat meat declined from 8.38 % in 1990 to 7.21 % in 2009 in total meat production in the country. As a conclusion,  mutton  and goat meat market registered a decline during the last decades, in favour of pork and poultry meat.

    1985-01-01

    Using the goat as a susceptible host and cattle as a resistant species to Fasciola hepatica infections, the humoral response of these animals to the surface of the newly excysted juvenile (NEJ) fluke was examined. Tegumental proteins of the NEJ were labeled with /sup 125/I by lactoperoxidase and analyzed after immunoprecipitation using a double antibody system. In addition, a comparison was made between the infected sera's capacity to immunoprecipitate surface antigens and their in vitro cytotoxic activity against the NEJ. In both goats and cattle the levels of NEJ surface antigens precipitated increased during the first 4 weeks PI. The peak immunoprecipitation of NEJ surface antigens by cattle sera (58%) was significantly higher than that of infected goat sera (33%). Immunoprecipitation of the available radiolabeled NEJ surface proteins by the infected cattle sera remained consistently higher than goat sera until the 16th week PI. The cytotoxic effects of these same caprine sera on NEJs in vitro was limited, while the cytotoxicity of the infected bovine sera closely approximated the sera's ability to precipitate NEJ surface antigens. There was also a qualitative difference between the species in their recognition of /sup 35/S and /sup 125/I radiolabeled NEJ surface antigens. Uninfected goat or cattle sera failed to precipitate any /sup 125/I or /sup 35/S-labeled surface proteins.

    Full Text Available Heads of sheep (n=180 and goats (n=120 slaughtered at four regions (Labraq, Shahat, Elbeida, and Masa of Green Mountain areas in Libya were investigated for the presence of larvae of Oestrus ovis. The animals were divided into sex and age groups. The heads were cut along longitudinal and sagittal axes, and the larvae (L1, L2, and L3 were collected. The infestation rate was significantly higher in sheep (51.66%; n=93/180 as compared to goats (28.33%; n=34/120. In sheep, the rate was higher during May (100%, while in goat, it was higher during August (70%. The incidence of L1 peaked in April (90% for sheep and October (100% for goats, while L2 reached to maximum in May for sheep (26.95% and goats (75%. L3 reached to peak in February (50% for sheep, and June (25% for goats. Mean intensity of larval burden was higher in sheep than goat, reaching to peak in June (9.1 larvae/head for sheep and March (3.5 larvae/head for goats. The infestation rate was significantly higher in males than females. The older animals were mostly affected as compared to younger animals. Highest infestation rate was recorded in Masa (45.83%, and the lowest rate was found in Labraq (40.27%. In conclusion, these findings may be used in designing the control strategies of myiasis in Libya.

  11. Scientific Opinion on the safety and efficacy of Yea-Sacc® (Saccharomyces cerevisiae as a feed additive for cattle for fattening, goats for fattening, dairy cows, dairy sheep, dairy goats and buffaloes

    Directory of Open Access Journals (Sweden)

    EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP

    2014-05-01

    Full Text Available Yea-Sacc® is an additive based on a live preparation of a strain of Saccharomyces cerevisiae intended for use as a zootechnical additive. It is produced in a powder (Yea-Sacc® and in a prills (Yea-Sacc® TS form. Saccharomyces cerevisiae is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. As the identity of the production strain has been established, safety for the target species, consumer and the environment is presumed. Both formulations are non-irritant to skin, Yea-Sacc® TS is non-irritant to the eye whilst Yea-Sacc® is a moderate irritant. In the absence of data both formulations should be considered skin sensitisers. As both forms are highly proteinaceous, they should be considered as potential respiratory sensitisers. Yea-Sacc® TS is designed to reduce dustiness and no significant exposure of users is to be expected for this form. In the absence of data on the dusting potential of Yea-Sacc®, it would be prudent to treat it as a respiratory sensitiser. Based on the results of four trials Yea-Sacc® was shown to have the potential to increase milk production in dairy cows when supplied at a minimum dose of 5 x 107 CFU/kg complete feed. As the mechanism of action of the additive can be reasonably assumed to be same, efficacy for minor species used for milk production can be presumed when used at the same minimum dose. Yea-Sacc® was also shown to have a potential to improve the production of cattle raised for fattening at a minimum dose of 1 x 108 CFU/kg complete feed. As the mechanism of action of the additive can be reasonably assumed to be same, efficacy for minor ruminant species reared for meat production can be presumed at a minimum dose of 1 x 108 CFU/kg complete feed.

    Full Text Available Abstract Background Echocardiography is a non-invasive method for assessment of the ovine and caprine heart. Complete reference ranges for cardiac dimensions and time indices for both species are not currently available and reliability of these measurements has not been evaluated. The objectives for this study are to report reliability, normal cardiac dimensions and time indices in a large group of adult sheep and goats. Fifty-one adult sheep and forty adult goats were recruited. Full echocardiographic examinations were performed in the standing unsedated animal. All animals underwent echocardiography four times in a 72-hour period. Echocardiography was performed three times by one author and once by another. Images were stored and measured offline. Technique and measurement repeatability and reproducibility and any differences due to animal or day were evaluated. Reference ranges (mean ± 2 standard deviations were calculated for both species. Results Majority of the images obtained were of good to excellent quality. Image acquisition was straightforward with 5.4% of animals demonstrating a small scanning window. Reliability was excellent for majority of dimensions and time indices. There was less variation in repeatability when compared with reproducibility and differences were greater for technique than for measurements. Dimensions that were less reliable included those for right ventricular diameter and left ventricular free wall. There were many differences in cardiac dimensions between sheep and goats. Conclusions This study has demonstrated that specific reference ranges are required for these two species. Repeatability and reproducibility were excellent for the majority of cardiac dimensions and time indices suggesting that this technique is reliable and valuable for examination of clinical cases over time and for longitudinal research studies.

    Members from Rickettsiales such as Anaplasma phagocytophilum, Ehrlichia chaffeensis, and some spotted fever group (SFG) Rickettsiae are important tick-borne pathogens. One hundred goats and sheep from southeastern China were examined for the presence of Anaplasma, E. chaffeensis, and SFG Rickettsiae by PCR. A. phagocytophilum, Anaplasma bovis, and Anaplasma centrale were detected in 15, 49, and 16 samples, respectively. The A. phagocytophilum and A. centrale were highly homologous to strains from Japanese sika deer and Japanese cattle, respectively, whereas a diversity of A. bovis sequences were detected. New genetic variants of Anaplasma close to A. centrale have been revealed. No Ehrlichia was detected in this study. The presence of SFG Rickettsiae was determined in 26 samples. The coinfection with more than two pathogens tested in this study was as high as 29%. This study has molecularly characterized the circulation of Anaplasma and Rickettsiae in goats and sheep in southeastern China, which highlights the risk of contracting the pathogens upon tick exposure.

    Full Text Available A multiresidue method (LC-MS/MS for determination of wide range of anthelmintics was developed. The method covered benzimidazoles: albendazole (and metabolites, cambendazole, fenbendazol (and metabolites, flubendazole (and metabolites, mebendazole (and metabolites, oxibendazole, thiabendazole (and metabolites, triclabendazole (and metabolites; macrocyclic lactones: abamectin, doramectin, emamectin, eprinomectin, ivermectin, moxidectin; salicylanilides: closantel, ioxynil, nitroxynil, oxyclosamide, niclosamide, rafoxanid and others: clorsulon, derquantel, imidocarb, monepantel (and metabolites, morantel, praziquantel, and pyrantel. The method was used to examine the potential presence of anthelmintics in goat and sheep milk and dairy products from the Polish market. A total of 120 samples of milk, yoghurt, cottage cheese, cream cheese, and curd were analysed. None of the samples were found positive above CCα (1-10 μg/kg except for one cottage cheese in which traces of albendazole sulfone were detected (5.2 ug/kg and confirmed. The results of the study showed negligible anthelmintic residues in the goat and sheep milk and dairy products and confirm their good quality.

    2010-01-01

    Full Text Available Schemes for on-farm welfare assessment in sheep and goats are not yet available. Factors responsible for this lack of availability are discussed in the first part of this review. Requisites for reliable methods of welfare assessment to be used in sheep and goat farms are discussed, taking into account the peculiarities of the small ruminant production systems in terms of flock management and farm location. Some housing parameters related to structures, design and micro-environment are reviewed and could be included in schemes of welfare assessment on farm. Human-animal interaction, health status of the animals in terms of body condition scoring, skin and hair conditions, lameness and injuries, and management practices in relation to cleanliness, animal handling and moving, milking procedures and abnormal behaviours, are proposed as potential animal-based indicators. When available, validity, reliability and feasibility of the proposed parameters are discussed. The voluntary adhesion to welfare standards in Sardinia and the application of a scientifically validated protocol in Basilicata are reported as examples of practical experiences.

  17. THE RUMINANT EFFECT OF VEGETAL LECITHIN AT SHEEP AND GOATS

    Directory of Open Access Journals (Sweden)

    H. SĂRĂNDAN

    2013-07-01

    Full Text Available In the extraction process of the vegetable soy oils and sun-flower oils results in large quantities a waste that contains approximately 45% fat from which 58% is lecithin. This waste called “dreg” creates problems of environment pollution because we didn’t find a use for it. We tested this waste in the food of small ruminants, at sheep and goat, watching the ruminant effect and the apparent digestibility of the nutritive substances in the food. The tested doses of “dregs” were of 100 g and 200 g per day. The food supplementation in sheep and goats with dregs up to 7% fat in the dry substance of the ration has favourable and proportional effects with the dose of fat on the digestibility of the nutritive substances from the food. The growth of ruminant bacteria is favoured at the 100 g dose of dregs but is depressed at the 200 g dose of dregs. On the ruminant protozoa the supplementation with fat from dregs leads to the reducing of the number of protozoa and even at defaunation. It is possible that the fat from the dregs to be a source of YATP and to protect the alimentary proteins of the degrading with proteolytic enzymes and therefore to make the protein ruminant by-pass.

    A cross sectional study of small ruminant mange mites was conducted from November 2011 to April 2012 on a total of 324 sheep and 680 goats, to determine the prevalence of mange mites in sheep and goats, identifying the major species of mite and to determine the potential risk factors significantly predicting the disease. The result showed an overall mange mite prevalence of 7.5 % (95 % CI 5.5-9.5) in goats and 1.2 % (95 % CI 0.5-1.9) in sheep. The mites identified were Sarcoptes and Demodex in goats and Sarcoptes and Psoroptes in sheep. The prevalence of mange mites was significantly higher in goats than in sheep (χ(2) = 16.636, P = 0.000). There was higher prevalence of mange mites in poor body condition than good body condition sheep and goats and the difference was statistically significant (χ(2) = 5.513, P = 0.019 in sheep and χ(2) = 141.85, P = 0.000 in goats). But age and sex of the host animals and agro climates were not statistically significant predictors of prevalence of mange mite. This study demonstrated that mange mites are among the major parasitic health problems of shoats in Eastern Amhara region that require urgent control intervention. PMID:27065612

    Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne virus, which causes a serious illness with case-fatality rates of up to 80% in humans. CCHFV is endemic in many countries of Africa, Asia and Southeastern Europe. Next to the countries with endemic areas, the distribution of CCHFV is unknown in Southeastern Europe. As the antibody prevalence in animals is a good indicator for the presence or absence of the virus in a region, seroepidemiological studies can be used for the definition of risk areas for CCHFV. The aim of the present study was to reveal which ruminant species is best suited as indicator for the detection of a CCHFV circulation in an area. Therefore, the prevalence rates in sheep, goats and cattle in different regions of Albania and Former Yugoslav Republic of Macedonia were investigated. As there are no commercial tests available for the detection of CCHFV-specific antibodies in animals, two commercial tests for testing human sera were adapted for the investigation of sera from sheep and goats, and new in-house ELISAs were developed. The investigation of serum samples with these highly sensitive and specific assays (94-100%) resulted in an overall prevalence rate of 23% for Albania and of 49% for Former Yugoslav Republic of Macedonia. Significant lower seroprevalence rates for CCHFV were found in cattle than in small ruminants in given areas. These results indicate that small ruminants are more suitable indicator animals for CCHFV infections and should therefore be tested preferentially, when risk areas are to be identified.

    Full Text Available This study was conducted by using a survey made at 80 enterprises from 63 villages with the aim of determining situations, problems and solution proposals related to the sheep and goat farms in Kastamonu province. The average age of the farmers was 49.3 years. The farmers were 8.75% of primary school graduates, 68.75% of secondary school and also 22.6% of illiterate. The enterprises have raised animals as 31.75% of state + own land and 68.75%’ of private + leased land. Also they are kept the rate of 70% Hair goat, 30% Angora goat and 55% Merino sheep, 42.5% Akkaraman sheep, and 16.25% Turkmen genotype, 7.5% Sakız sheep and 6.25% of Kıvırcık Sheep. The average flock sizes goat and sheep enterprises were 77.3 head goats and 71.7 heads sheep, respectively. Sixty percent of the breeder feed their animals on the pasture for 8-10 months and only 30% the breeders give supplementary feeding before and during mating period. The enterprises have 31.2% parturition chamber and 92.5% lamb growth areas. While all enterprises are routinely used to protective vaccines but only used disinfectant of 73.7% enterprises. The reason of sheep and goat breeders is majority contributions of income and habits. So, flock sizes are small (74.5 heads animal. In conclusion, young people by encouraging small animal farming in the province of Kastamonu, should be given to technical, economic support and educational seminars. In the future, as the sole source of income and a large flock size may lead to a development of sheep and goat breeding in Kastamonu province.

    Full Text Available A confirmed case of human brucellosis motivated an investigation into the potential source of infection in Namibia. Since domestic animals are principal sources of Brucella infection in humans, 1692 serum samples were screened from sheep, goats and cattle from 4 presumably at-risk farms and 900 springbok (Antidorcas marsupialis serum samples from 29 mixed farming units for Brucella antibodies by the Rose-Bengal test (RBT and positive cases confirmed by complement fixation test (CFT. To assess the prevalence of human brucellosis, 137 abattoir employees were tested for Brucella antibodies using the standard tube agglutination test (STAT and by enzyme linked immunosorbent assay (ELISA. Cattle and sheep from all 4 farms were negative by RBT and CFT but 2 of the 4 farms (Ba and C had 26/42 and 12/285 seropositive goats, respectively. Post mortem examination of seropositive goats revealed no gross pathological lesions typical of brucellosis except enlarged mesenteric and iliac lymph nodes seen in a single buck. Culture for brucellae from organs of seropositive animals was negative. None of the wildlife sera tested positive by either RBT or CFT. Interviews revealed that besides the case that prompted the investigation, a family and another person from other farms with confirmed brucellosis shared a common history of consumption of unpasteurised goat milk, home-made goat cheese and coffee with raw milk and prior contact with goats, suggesting goats as the likely source of infection. All 137 abattoir employees tested negative by STAT, but 3 were positive by ELISA. The 3 abattoir workers were clinically normal and lacked historical connections with clinical cases. Although goats are often associated with B. melitensis, these studies could not explicitly implicate this species owing to cross-reactivity with B. abortus, which can also infect goats. Nevertheless, these data reinforce the need for a better National Control Programme for brucellosis in Namibia.

    Genetically engineered sheep and goats represent useful models applied to proof of concepts, large-scale production of novel products or processes, and improvement of animal traits, which is of interest in biomedicine, biopharma, and livestock. This disruptive biotechnology arose in the 80s by injecting DNA fragments into the pronucleus of zygote-staged embryos. Pronuclear microinjection set the transgenic concept into people's mind but was characterized by inefficient and often frustrating results mostly because of uncontrolled and/or random integration and unpredictable transgene expression. Somatic cell nuclear transfer launched the second wave in the late 90s, solving several weaknesses of the previous technique by making feasible the transfer of a genetically modified and fully characterized cell into an enucleated oocyte, capable of cell reprogramming to generate genetically engineered animals. Important advances were also achieved during the 2000s with the arrival of new techniques like the lentivirus system, transposons, RNA interference, site-specific recombinases, and sperm-mediated transgenesis. We are now living the irruption of the third technological wave in which genome edition is possible by using endonucleases, particularly the CRISPR/Cas system. Sheep and goats were recently produced by CRISPR/Cas9, and for sure, cattle will be reported soon. We will see new genetically engineered farm animals produced by homologous recombination, multiple gene editing in one-step generation and conditional modifications, among other advancements. In the following decade, genome edition will continue expanding our technical possibilities, which will contribute to the advancement of science, the development of clinical or commercial applications, and the improvement of people's life quality around the world.

  7. Efficacy of Levamosole in Treatment of Gastrointestinal Nematodes of Goats and Sheep at Kiboko

    International Nuclear Information System (INIS)

    Simple faecal egg count reduction test was done on days 10, 14 and 28 post treatment respectively, to evaluate the efficacy of Levamisole HCl in the treatment of helminthiasis in goats and sheep. Levamisole HCl given at the manufacturer's recommended dosage rate was more effective in sheep than in goats. Therefore, goats require a substantially increased dosage of Levamosole HCl for effective treatment results. The main aim of this study was to highlight the importance of field trials for specific anthelminitic drugs commonly used for strategic control of helminths affecting different livestock species kept under different management systems

    Thang Truong

    Full Text Available Peste des petits ruminants (PPR is a viral disease which primarily affects small ruminants, causing significant economic losses for the livestock industry in developing countries. It is endemic in Saharan and sub-Saharan Africa, the Middle East and the Indian sub-continent. The primary hosts for peste des petits ruminants virus (PPRV are goats and sheep; however recent models studying the pathology, disease progression and viremia of PPRV have focused primarily on goat models. This study evaluates the tissue tropism and pathogenesis of PPR following experimental infection of sheep and goats using a quantitative time-course study. Upon infection with a virulent strain of PPRV, both sheep and goats developed clinical signs and lesions typical of PPR, although sheep displayed milder clinical disease compared to goats. Tissue tropism of PPRV was evaluated by real-time RT-PCR and immunohistochemistry. Lymph nodes, lymphoid tissue and digestive tract organs were the predominant sites of virus replication. The results presented in this study provide models for the comparative evaluation of PPRV pathogenesis and tissue tropism in both sheep and goats. These models are suitable for the establishment of experimental parameters necessary for the evaluation of vaccines, as well as further studies into PPRV-host interactions.

    Full Text Available This study was conducted to isolate and identify organisms responsible for sub-clinical mastitis (SCM in goats and sheep for the determination of point prevalence of SCM and antibiotic sensitivity of the identified organisms. For this purpose 50 each of lactating sheep and goats were examined with the commercially available Leucocytest® SCM detection kit. It was found that 4 and 36% sheep and goats suffered from SCM, respective. The prevalence of clinical mastitis (CM was 4 and 6% in sheep and goats, respectively. Milk samples were collected individually from sheep and goats with SCM and were cultured in different media including nutrient agar, blood agar and eosin methylene blue agar. The bacteria were further characterized by biochemical tests. In both goats and sheep, the organisms responsible for SCM were Staphylococcus aureus and Escherichia coli. The organisms were found most sensitive to gentamicin (Gn. After Gn treatment to goats and sheep with SCM, total bacterial counts decreased and milk production significantly increased compared to levels prior to treatment. It is suggested from the study that early detection of SCM and treatment with proper antibiotics can control SCM in goats and sheep.

    Full Text Available Abscess disease (caseous lymphadenitis and Morel disease is a worldwide contagious bacterial disease of sheep and goats and is adversely affecting the development of the sheep industry in Saudi Arabia. Fifteen sheep and 12 goat farms at Qassim region, central Saudi Arabia, were surveyed during September and October 2008 for the determination of the prevalence and the etiology of abscess disease. One hundred and twenty pus samples were collected from affected external lymph nodes of clinically-ill sheep and goats and from infected internal lymph nodes and organs condemned during meat inspection in the slaughterhouses, for the isolation and identification of pathogenic bacteria causing sheep abscess disease. The prevalence of abscess disease varied between 5%– 44.1% in sheep farms, being highest in the Najdi breed, and between 2.2 % – 6.5 % in goat farms. Males of both sheep and goats had the highest rate of infection compared to females (p <0.01. Bacterial isolates were obtained from 97 out of the 120 collected pus samples (80.83%. The remaining 23 samples were sterile. Corynebacterium pseudotuberculosis and Staphylococcus aureus subsp. anaerobius accounted for about 54% of isolates, with almost equal frequencies (p =0.5. Other pyogenic bacteria such as S. aureus, Streptococci, Pseudomonas aeruginosa, Actinomyces pyogenes were also isolated from infected abscesses. They represented about 46% of the isolated etiological agents of sheep abscesses. This explains why available vaccines (bactrins against caseous lymphadenitis (CLA are poorly protective against abscess disease in Saudi Arabia. [Vet. World 2011; 4(11.000: 495-499

    Full Text Available The introduction of HACCP system within sheep exploitations represents a unitary control manner, scientifically proved, which enforces the discipline and correctness, allows an objective evaluation of sheep and goat meat and milk quality. When determining the main components of sheep and goat milk from the animals that grazed on the pasture fertilized with stable manure, within ecologic conditions, the following results were obtained: at sheep there was a fat percent of 6.22% and 6.11%, protein 5.32% and 5.52%, and dry substance 14.25% and 14.21%, normal values for sheep milk; at goats the fat percent was that of 6.22% and 6.11%, protein 5.32% and 5.52%, and dry substance 14.25% and 14.21%, normal values for goat milk. The milk samples taken from the sheep belonging to Palas Merino breed and from Carpatina breed were also analysed with regard to the toxic residues and it has been stated that the values obtained fit within the normal norms admitted by the food domain’ standards, being in compliance with the safety and protection of the consumers. The elimination of chemical fertilizers, pesticides and herbicides has led to the non-noticing of their presence within the sheep and goat products. By the regulation of ecologic products’ quality, in relation with the consumers’ and environment’s protection, a balance was created between the producers’ interests and obligations, those of the merchants and also those of the consumers. On the basis of results obtained through the microbiological examination of milk and meat samples taken from the sheep it has been stated that the microbial flora identified is formed by representatives of Staphylococcus–72.72% Streptococcus β hemolitic – 9.09% and Fungi filamentous – 18.18%. The microbial flora is non pathogen for man.

    Full Text Available The minimum dose required to cause infection of Romney and Suffolk sheep of the ARQ/ARQ or ARQ/ARR prion protein gene genotypes following oral inoculation with Romney or Suffolk a sheep Bovine spongiform encephalopathy (BSE-derived or cattle BSE-derived agent was investigated using doses ranging from 0.0005g to 5g. ARQ/ARQ sheep which were methionine (M / threonine (T heterozygous or T/T homozygous at codon 112 of the Prnp gene, dosed ARQ/ARR sheep and undosed controls did not show any evidence of infection. Within groups of susceptible sheep, the minimum effective oral dose of BSE was found to be 0.05g, with higher attack rates following inoculation with the 5g dose. Surprisingly, this study found no effect of dose on survival time suggesting a possible lack of homogeneity within the inoculum. All clinical BSE cases showed PrPd accumulation in brain; however, following cattle BSE inoculation, LRS involvement within Romney recipients was found to be significantly lower than within the Suffolk sheep inoculated group which is in agreement with previous reports.

To determine the infection rate of toxoplasmosis in sheep and goats in east Azarbaijan province of Iran a total of 186 sera, 13 fetal brains, 13 cotyledons and 34 whole blood samples were collected from sheep and goats in Tabriz abattoir during the year 2010. Serum samples were tested for IgG antibodies against Toxoplasma gondii by Enzyme Linked Immunosorbent Assay (ELISA. This test is used in conjunction with direct and nested PCR techniques for detection of T. gondii DNA in blood,cotyledon and brain of fetuses, using 4 pairs of universal and specific primers, 18SrRNA, ITS-1, (Tg1,Tg2and (Tg3,Tg4. Antibodies against T. gondii were found in 18.3% serum samples. DNA of T. gondii was detected in 69% of fetal brains, 23% of cotyledons and 14.7% of blood samples. The prevalence rate of T. gondii in sheep was 24.8% and in goats was 10.6% and the significant difference was observed between sheep and goats groups (p≤0.05. The prevalence of toxoplasmosis antibodies was significantly higher in adult sheep and goats than younger animals. There was significant difference between male (10.5% andfemale (19.2% sheep and goat was observed (p≤0.05. Detection of T. gondii DNA using PCR minimizes the problems which the researcher may face when using serological methods and facilitates diagnosis incomplex cases. The presence of T. gondii in blood, fetal tissues and neonatal specimens strongly suggests active and or congenital infection.

    Cystic Echinococcosis (CE) caused by Echinococcus granulosus sensu lato (s.l.) is a neglected helminth zoonosis affecting humans and various animal species. Human CE has been reported in almost all countries of sub-Saharan Africa but its prevalence and public health impact are subject to large geographical variations. The reasons for these differences are not well understood; among other factors, occurrence of different species/genotypes of E. granulosus s.l. has been suggested. CE is very common in all livestock species in Ethiopia; human CE is poorly documented in the country. The aim of this study was to assess the fertility and molecularly characterize hydatid cysts collected from cattle, camels, goats and pigs from different parts of the country. From the 137 samples characterized by PCR-RFLP and sequencing, 115 (83.9%) were identified as E. granulosus s.s. (G1, common sheep strain), 6 (4.4%) as Echinococcus ortleppi (G5, cattle strain) and 16 (11.7%) as Echinococcus intermedius (G6/7, camel strain). In cattle, E. granulosus s.s. and E. ortleppi were found; in camels and goats, E. granulosus s.s. and E. intermedius; two cysts found in pigs were identified as E. granulosus s.s. and E. ortleppi, respectively. All cysts recovered from goats and pigs were sterile, while fertility was 34% and 50% in cysts from cattle and camels, respectively. In cattle, 31% of E. granulosus s.s. cysts were fertile, showing the importance of cattle in the transmission of the "sheep strain". Next to E. granulosus s.s., E. intermedius (camel strain) was the predominant species: 34.4% of the cysts collected from camels and 62.5% from goats were identified as E. intermedius. These animals originated from the drier Central, Eastern and Southern parts of the country. For the first time, we showed the presence of CE in pigs in Ethiopia. The presence of these strains and especially the fact that the zoonotic E. granulosus s.s. and E. intermedius are dominant, make CE an important public

    Gastrointestinal nemathelminths affect productive as well as reproductive performance of a wide range of ruminants. To assess the impact of anthelmintic treatment on gain in body weight (b. wt.) of sheep and goat, a study was conducted using two different flocks of sheep and goats each maintained in semi intensive system. Infected animals in both the flocks were divided into three groups each. Group I and II in each flock were treated with levamisole (@7.5 mg/kg b. wt. subcutaneously) and fenbendazole (@5 mg/kg b. wt. orally), respectively. Animals of group III were kept as untreated control. Individual b. wt. and faecal egg count were recorded up to 42nd day post treatment. Results showed 100 % reduction in faecal egg count of sheep on day 7 after treatment with levamisole and on day 10 after treatment with fenbendazole. In goats, the reduction in faecal egg count was 82.60 % after treatment with levamisole and 78.87 % after treatment with fenbendazole on day 14 post treatment. The study also revealed mean increase of 29.57 and 22.67 % in b. wt. of sheep treated with levamisole and fenbendazole respectively 42nd day post treatment whereas mean b. wt. of infected untreated control groups decreased by 7.14 %. Similarly, there was an increase of 10.71 and 14.47 % in mean b. wt. of goats 42nd day post treatment with levamisole and fenbendazole, respectively whereas mean b. wt. of untreated control group decreased by 15.38 %. More weight gain was recorded in sheep as compare to goats after treatment as compared to the untreated control group, which may be due to some drug resistance in goat and required clarification by further studies in these ecological zones of Udham Singh Nagar.

    This article explored the formation of volatile compounds during the production of kefir from goat and sheep milks with high polyunsaturated fatty acids (PUFA) as a result of feeding animals forage supplemented with maize dried distillers grains with solubles (DDGS). The increased PUFA content of the goat and sheep milks resulted in significant changes to the fermentation process. In particular, apart from an increase in the time taken to ferment sheep milk, fermentation yielded less 2,3-butanedione. The highest quantities of this compound were assayed in kefir produced from goat milk with an increased content of PUFA. An increase of PUFA significantly elevated ethanal synthesis during lactose-alcohol fermentation of sheep milk. Neither the origin of milk (sheep or goat) nor the level of PUFA had any statistical effect on the amount of ethanal assayed during the fermentation of milk and within the finished product. The proportion of l(+)-lactic acid was higher in kefirs produced using goat milk compared with sheep milk and did not depend on the content of PUFA in milk fat. The content of PUFA had a significant effect on the aroma profile of the resulting kefirs. An increase in PUFA content resulted in the loss of whey aroma in goat milk kefirs and the animal odor in sheep milk kefirs, and a creamy aroma became more prevalent in kefirs made from sheep milk.

    Full Text Available years, but recently there have been reports of prophylaxis failure under natural conditions. In this study, use of the drug for prophylactic purpose against trypanosomosis in small ruminants was investigated. Forty-two sheep and 44 goats were divided into four treatment groups. Groups 1 and 2 were treated with isometamidium chloride (Samorin(R, Rhone Merieux, Lyon, France at 3-month intervals while groups 3 and 4 were used as controls. All the animals were exposed to natural tsetse challenge and monitored for serum isometamidium levels and anti-trypanosome antibodies. Seven days after drug administration, isometamidium levels were significantly higher in goats 13.7 + 0.07 ng/mℓ than in sheep 6.2 + 0.06 ng/mℓ. However, the elimination half-life in the sheep was 14.2 + 0.92 days and was significantly higher (P > 0.05 than that of the goats 12 + 0.5 days. This study established that isometamidium metabolism differs between sheep and goats and this difference may have important implications in high tsetse challenge areas.

    Few studies have been carried out in Africa to estimate the prevalence of Taenia hydatigena. With the aim to determine the prevalence of T. hydatigena in slaughtered pigs and small ruminants (goats and sheep) in Mbeya, Tanzania, two cross-sectional surveys were carried out investigating pigs in April to May 2014 and small ruminants in September 2012. In total, 243 pigs were examined post-mortem for T. hydatigena cysts which were found in 16 (6.6 %) pigs. The majority (80 %) of cysts were found on the omentum and the rest on the liver (20 %), all on the visceral surface. Two pigs were also found infected with Taenia solium but showed no signs of other infections. A total of 392 goats and 27 sheep were examined post-mortem, and the prevalence of T. hydatigena was similar in goats and sheep with 45.7 and 51.9 %, respectively. DNA sequencing of the mitochondrial cytochrome c oxidase subunit 1 gene (cox1) from a subsample of metacestodes from goats and sheep confirmed the T. hydatigena infection. The prevalence found in small ruminants was comparable to other studies conducted in Africa, but for pigs, it is one of the highest recorded to date. The present study also confirms the occurrence of T. hydatigena and T. solium in pigs from Mbeya. Further studies are needed to determine the impact of T. hydatigena on production under sub-Saharan conditions and the financial consequences for smallholder farmers. PMID:26210397

  4. The effect of plane of nutrition on the urinary purine derivative excretion in sheep and goats

    International Nuclear Information System (INIS)

    An experiment was conducted to determine the effect of plane of nutrition on purine derivative excretion and to develop a set of model equations that relate intake to the purine derivative (PD) excretion in sheep and goats. Four male Sabi sheep and four male Small-East African goats (four months old) were used. The trial was a 4 x 4 Latin square cross-over design to examine the response of PD excretion to feed intake. The four diets consisted of star grass (Cynodon nlemfuensis) hay fed ad libitum, and at 85, 70 or 55% of ad libitum. Total PD excretion increased with the increase in feed intake for both sheep and goats. However, the increase did not reach statistical significance (P > 0.05). The model equations relating digestible organic matter intake (X) to PD excretion (Y) were Y = 2.97 X + 0.15 (R2=0.72) and Y = 5.86 X - 0.33 (R2=0.99) for sheep and goats respectively. (author)

    Full Text Available Abstract Two techniques that make it possible to isolate telomere DNA are presented, using sheep as an example. The first technique is based upon the screening of a sheep BAC library with PCR amplified DNA segments preserved from high-power laser beam irradiation. Twenty-three BACs hybridising to 13 subtelomeric regions in sheep and goats were obtained (out of 27 in the sheep complement, of which 13 recognised more than one region, telomeric or not. Twenty-three microsatellites were isolated from these BACs and 22 were genetically mapped on the sheep international genetic map, always consistently with the cytogenetical localisation in 17 cases out of 22. These results are discussed. The second technique is based upon the selective cloning of subtelomeric enriched DNA. Preliminary results were obtained by this approach.

    Full Text Available Abstract Background Anthelmintic treatment is the most common way of controlling nematode infections in ruminants. However, several countries have reported anthelmintic resistance (AR, representing a limitation for sustainable small ruminant production. The knowledge regarding worm control management represents a baseline to develop a guideline for preventing AR. The aim of the present study was therefore to improve our knowledge about the worm control practices in small ruminant flocks in Norway. Methods A questionnaire survey regarding worm control practices was performed in small ruminant flocks in Norway. Flocks were selected from the three main areas of small ruminant farming, i.e. the coastal, inland and northern areas. A total of 825 questionnaires, comprising 587 sheep flocks (return rate of 51.3% and 238 goat flocks (52.6% were included. Results The results indicated that visual appraisal of individual weight was the most common means of estimating the anthelmintic dose used in sheep (78.6% and goat (85.1% flocks. The mean yearly drenching rate in lambs and ewes were 2.5 ± 1.7 and 1.9 ± 1.1, respectively, whereas it was 1.0 (once a year in goats. However, these figures were higher in sheep in the coastal area with a rate of 3.4 and 2.2 in lambs and ewes, respectively. Benzimidazoles were the predominant anthelmintic class used in sheep flocks (64.9% in 2007, whereas benzimidazoles and macrocyclic lactones were both equally used in dairy goat flocks. In the period of 2005-2007, 46.3% of the sheep flocks never changed the anthelmintic class. The dose and move strategy was practiced in 33.2% of the sheep flocks. Conclusions The present study showed that inaccurate weight calculation gives a risk of under-dosing in over 90% of the sheep and goat flocks in Norway. Taken together with a high treatment frequency in lambs, a lack of anthelmintic class rotation and the common use of a dose-and-move strategy, a real danger for development of

    Full Text Available A study to estimate the prevalence of sheep and goats skin defect was carried out at Bahir Dar Tannery. A total of 400 (200 sheep and 200 goat sheep and goat skins were sampled and examined for skin defect at pickled stage. The study showed that there were different skin defects responsible for the decline in quality grades of skin. From the total skin examined, ekek (58.3%, scratch (22.5%, flying defect (13.8 and scar (11.3% were common defects. For sheep skins ekek (67%, processing defect (12.5%, scratch (12% and processing defect (8.5% were important skin defects and only small number (8.5% were with no defect. In goats skin, ekek (49.5%, scratch (33%, scar (17.5% and flying defect (15% were important defects. Skin quality grades 6 (22.3%, 5 (21.8% and 4 (18.5% were frequently observed skin grades. There were unappreciable numbers of rejects (12% while quality grade 1 was the least frequent (6.3%. Ekek was significantly (p0.05 different between the two species. Examination also showed that 26 (13.5% and 22 (11% were rejected in sheep and goat skins, respectively. Integrated efforts towards good animal husbandry and animal health care are very important for better quality skin. Furthermore, detailed studies on the distribution, seasonal occurrence and the direct and indirect economic impact of ectoparasites should be undertaken. Meanwhile, tanneries should collaborate with such studies to maximize the economic gain in the long run.

    Full Text Available From a complex experiment of establishing the effects of lecithin supplemented in the diet of small ruminants, in this paper we present the influence of lecithin on some sanguine biochemical parameters at lactating sheep and goat. The researches were made on a experimental group formed by 5 sheep from łurcana breed and 5 goats from Crapatina breed, which were fed in the first experimental period with a base ratio (Br formed by 1.5 kg of hill hay and 0.2 kg concentrate forage mixture, in the second experimental period the Br was supplemented with 100 g lecithin/day/animal. At the end of each experimental period were taken blood samples to establish some biochemical parameters from sanguine serum. The supplementation of base ration with 100 g lecithin/day/animal at lactating sheep and goats did not produced significant changes to values of total proteins (TS, albumin, creatinine, urea and total bilirubins (TB from sanguine serum. Contrary to expectation the cholesterol and triglycerides were higher than normal both in sheep (from 82 mg/dl to 83 mg/dl for cholesterol and from 23 mg/dl to 45 mg/dl for triglycerides but specially in goats (from 59 mg/dl to 68 mg/dl for cholesterol and from 24 mg/dl to 55 mg/dl for triglycerides. Were registered significant increment of activity of alkaline phosphatase and in γ – GT and a decrease of plasmatic activity of pancreatic α-amylase both in sheep and goats.

    HoBi-like viruses are an emerging species of pestiviruses associated with respiratory and reproductive disease in cattle and in water buffaloes. Although cattle appear to be the main natural hosts, little is know about the potential for HoBi-like viruses to be transmitted to other livestock. In this study, seronegative calves, goats and pigs, and sheep harboring pestivirus antibodies (probably due to previous exposure to BVDV) were exposed to HoBi-like viruses either by direct inoculation (GIn) or by contact with calves persistently infected with HoBi-like viruses (GEx). Both GIn and GEx groups were monitored for clinical signs, lymphocyte count, virus in buffy coats and nasal swabs up to day 18 post-inoculation (pi). Evidence of transmission of HoBi-like virus by PI calves was observed in all studied species. No difference in clinical presentation was observed between animals in the GIn or GEx groups. Evidence of infection, depending on the species included lymphocyte depletion, fever, viral RNA detection, and/or seroconversion. Depletion of lymphocytes was observed in calves and goats (35% and 50%, respectively) but not in pigs. Seroconversion was observed in at least one animal of each group and for all exposed species. The rate of seroconversion was higher in animals in the GIn experimental groups. In sheep, pre-existing moderate to high neutralizing titers against BVDV did not prevent viral replication and shed. The study demonstrated that naive cattle, goats and pigs, in addition to antibody positive sheep, can be infected by HoBi-like virus via persistently infected calf and potentially transmit the virus.

    Full Text Available It has been demonstrated that positive tissue samples from an active case in Turkana had viral RNA from a lineage III PPRV and the first available genome sequence was determined. Seven goats and sheep aged between 3-6 months that were tested to be negative for PPR antibodies by competitiveELISA were used for study. These animals were divided into two treatment groups and one control group. Each animal in the treatment groups was inoculated through intranasal route with 2ml of 30% infected mixed tissue suspension while the control group was inoculated with phosphate buffered saline. Animals were then examined daily for development of PPR clinical signs. Clinical signs were observed in treatment groups while the control remained apparently healthy. Fever started to develop from 6.6 ±1.14 and 8.6 ±1.34 days post infection (dpi in goats and sheep respectively. There was a progressive rise in respiratory rates from 9 to 16 dpi in goats and from 9 to 14 dpi in sheep. Nasal discharges were recorded from days 8.2 ±2.28 and 9 ±1.83 post infection in goats and sheep respectively. Ocular discharges were observed from days 10±2.24 and 9.8±2.17 post infection in goats and sheep respectively. Oral lesions were observed only in one goat and two sheep. Diarrhea was observed from day 13.5±0.58 post infection in sheep and from day 14±1 post infection in goats.Gross pathology revealed lesions mainly in the lungs, body lymph nodes and the intestines. The results from this study indicate that whereas PPR is thought to mainly affect goats, the disease in Kenya appear to evenly affect both, goat and sheep.

    Full Text Available Rectal swabs from 155 sheep and 252 goats from Grenada were evaluated to determine the prevalence of Campylobacter spp., antibiotic resistance, and multilocus sequence types. Fifteen Campylobacter isolates were obtained (14 C. jejuni and 1 C. coli. The prevalence (3.7% did not differ significantly between sheep (4.5% and goats (3.2%. Among the seven antimicrobials tested, resistance was only detected for tetracycline (30.8% and metronidazole (38.5%. Campylobacter isolates showed no significant difference between sheep and goats for type of antimicrobial resistance or percent of resistant isolates. Twelve of the isolates were successfully genotyped consisting of four recognized clonal complexes and three novel sequence types. Importantly, one isolate from one goat was identified as the C. jejuni sequence type-8, a zoonotic and tetracycline-resistant clone reported to be a highly virulent clone associated with ovine abortion in the USA. Although most samples were from comingled sheep and goat production units, there were no shared sequence types between these two host species. None of the sequence types identified in this study have previously been reported in poultry in Grenada, suggesting sheep- and goat-specific Campylobacter clones in Grenada. This is the first report of genotyping of Campylobacter isolates from sheep and goats in the Eastern Caribbean.

    Peste des petits ruminants (PPR) is a contagious viral disease of sheep and goats common in Africa and Asia. Its high morbidity and mortality has a devastating impact on agriculture in developing countries. As an example, an Asian lineage IV strain of PPRV was responsible for mass fatalities among wild goats in Kurdistan in 2010/2011. In separate experiments, three sheep and three goats of German domestic breeds were subcutaneously inoculated with the Kurdish virus isolate; three uninfected sheep and goats were housed together with the inoculated animals. All inoculated animals, all in-contact goats and two in-contact sheep developed high fever (up to 41.7 °C), depression, severe diarrhea, ocular and nasal discharge as well as ulcerative stomatitis and pharyngitis. Infected animals seroconverted within a few days of the first detection of viral genome. Clinical signs were more pronounced in goats; four out of six goats had to be euthanized. Necropsy revealed characteristic lesions in the alimentary tract. Peste des petits ruminants virus (PPRV) RNA was detected in blood as well as nasal, oral and fecal swabs and tissues. The 2011 Kurdish strain of PPRV is highly virulent in European goats and spreads easily to in-contact animals, while disease severity and contagiosity in sheep are slightly lower. PPRV strains like the tested recent isolate can have a high impact on small ruminants in the European Union, and therefore, both early detection methods and intervention strategies have to be improved and updated regularly.

    Vaccines against gastrointestinal nematodes are one potential option for the control of parasitic gastroenteritis in ruminants. Excretory/secretory (E/S) and hidden antigens are being studied as candidates for vaccines against Haemonchus spp., which is a major parasite in cattle and small ruminants that are raised in warm climates. Protection has been observed after vaccination with some E/S proteases, particularly cysteine proteases and with some glycans that are abundant on the surfaces and in the secretory products of helminths. However, the most promising results are being obtained with glycoprotein antigens extracted from the microvillar surfaces of the Haemonchus contortus intestinal cells. These antigens are called 'hidden' because they are not exposed to the host's immune system during infection. Thus far, recombinant forms of these antigens have not been usefully protective. However, because only 5 μg of antigen is required per dose, production of a native antigen vaccine from adult parasites has been found to be practical and commercially viable. Trials indicate that a vaccine made from one particular isolate will cross-protect against geographically distant isolates. PMID:25891536

    Goats and sheep rank third and fourth in terms of global milk production from different species, but unlike cow milk, which has stringent hygiene and quality regulations, microbiological standards for the production and distribution of goat milk and sheep milk are more relaxed. Difficulties in managing the sanitary quality of sheep and goat milk derive from a series of factors including the low level of production per head, the milking system, the difficulty involved in machine milking, the conditions under which the herds or flocks are raised, adverse climatic conditions and the spread of production over a wide geographic area. Fresh goat milk is consumed by infants and others with allergies to cow milk and is also used for on-farm manufactured cheese, with or without thermal treatment. The high fat content and peculiar taste of cheeses made from ewe milk are also very popular. These cheese varieties, which are mostly still of 'artisan-type', are not covered by regulatory definitions and the dispute over the use of raw versus pasteurised milk is still alive. However, in documented intoxications recorded after the consumption of cheese, there has always been evidence of incorrect temperature control during pasteurisation, the deliberate addition of raw milk, or contamination during storage. Compositional differences between the milk from cows, ewes and goats (chemical composition of lipids, phosphatase level, freezing point, natural bacterial inhibitor levels, somatic cell count, etc.) preclude the nondiscriminatory use of bovine standards for regulatory purposes. Quality standards adjusted for the specifics of ewe/goat milk should be considered. The production of safe cheese is linked to a series of conditions which ensure consumer health, primarily pasteurisation. In the absence of pasteurisation, all cheeses made from raw milk should be subjected to strict periodic controls. PMID:9501361

    epidemiology of tuberculosis in goats and sheep using comparative intradermal tuberculin skin test, postmortem examination, mycobacteriological culture and molecular typing methods. The overall animal prevalence of TB in small ruminants was 0.5% (95% CI: 0.2%–0.7% at ≥4 mm and 3.8% (95% CI: 3%–4.7% at cutoff ≥2 mm. The herd prevalence was 20% (95% CI: 12–28% and 47% (95% CI: 37–56% at ≥4 mm and ≥2 mm cut-off points, respectively. The overall animal prevalence of Mycobacterium avium complex infection was 2.8% (95% CI: 2.1–3.5% and 6.8% (95% CI: 5.8–7.9% at ≥4 mm and ≥2 mm cut-off points, respectively. Mycobacteriological culture and molecular characterization of isolates from tissue lesions of tuberculin reactor goats resulted in isolation of Mycobacterium tuberculosis (SIT149 and non-tuberculosis mycobacteria as causative agents of tuberculosis and tuberculosis-like diseases in goats, respectively. The isolation of Mycobacterium tuberculosis in goat suggests a potential transmission of the causative agent from human and warrants further investigation in the role of small ruminants in epidemiology of human tuberculosis in the region.

    The objective was to determine the effect of forage quality on apparent total tract digestibility and ruminal fermentation in cattle versus sheep. Five yearling English crossbred (Hereford × Angus) steers (440.4 ± 35.6 kg of initial BW) and 5 yearling whiteface (Rambouillet × Columbia × Debouillet) wethers (44.4 ± 4.6 kg of initial BW), each fitted with a ruminal cannula, were randomly assigned to 1 of 3 forage sources within ruminant specie, and the study was conducted over 3 periods. For forage source, both animal and period served as the blocking factor with all forage sources represented once within each animal and all forage sources represented at least once within each period. The treatment structure was arranged in a 2 × 3 factorial with ruminant species (2) and forage source (3) as the factors. Forage sources were 1) alfalfa hay (Medicago sativa; 17.5% CP and 34.1% NDF, DM basis), 2) warm-season grass hay mix (Bothriochloa ischaemum and Cynodon dactylon; 7.3% CP and 74.7% NDF, DM basis), and 3) lovegrass hay (Eragrostis curvula; 2.5% CP and 81.9% NDF, DM basis). As a percent of BW, steers and wethers consumed similar (P ≤ 0.06) amounts of forage, and intake was more influenced by forage quality (P < 0.001) than ruminant species (P = 0.35). When expressed per unit of metabolic BW, cattle consumed more (P < 0.001) DM, NDF, and N than sheep. Apparent total tract digestibility was similar among steers and wethers when alfalfa or grass hay was fed, but decreased to a greater extent in wethers when low-quality lovegrass hay was fed (ruminant species × diet interaction, P ≤ 0.01). Rate (%/h) of ruminal NDF disappearance was greater (P = 0.02) for alfalfa and grass hay than lovegrass, but was not influenced (P = 0.12) by ruminant species. In addition, ruminal DM fill was influenced more (P < 0.01) by forage than by ruminant species (P = 0.07). Steers and wethers had greater (P < 0.01) DM fill from grass hay and lovegrass hay than alfalfa before and 5 h

    Full Text Available Milk composition and quality are affected by several factors of which stage of lactation and mammary gland health status represent the main ones. These two factors become more effective in small dairy ruminants, for which stage of lactation is synchronized as result of the seasonal breeding cycle. As a consequence in dairy sheep and goats milk quality and cheese making properties tend to decline. Most of these effects on milk quality are also associated with an increase in the somatic cell count (SCC, which is in turn related with the gradual involution of mammary gland with the lactation progress (Fantuz et al., 2001; Baldi et al., 2002. However, high SCC in milk could be related to intramammary infections (IMI, sub-clinical and chronic mastitis in both sheep and goats.

    Out of a total of 2,368 sheep and 3,156 goats tested against brucellosis by the Brewer's card test in the 5 Mohafadhas of the northern region of Iraq, 0.93% and 4.4% respectively were recorded as positive reactors. The highest incidence (1.36%) among sheep was found in the Kirkuk region while the lowest (0.78%) was in the Mosul (Nineveh) region. Among goats the highest incidence (11.55%) was revealed in the Dukho region while the lowest (1.47%) was in the Sulaimaniya region. The need for more detailed work on the incidence and on the isolation of the local strains, as well as the need for a control programme, is also discussed. PMID:505594

  15. Protein degradability of feedstuffs and its effect on sheep and goat productivity

    International Nuclear Information System (INIS)

    Dry matter and crude protein degradability of the main ruminant feeds were estimated using dacron bags. Formaldehyde treatment of soybean meal was the most effective protective agent reducing degradability. Fractional outflow rate of small particles from the rumen was affected by high temperatures in summer in sheep but not in goats. Feed intake and digestion coefficients of lambs for acid detergent fibre (ADF), and neutral detergent fibre (NDF) were higher than those of kids which had higher starch and nitrogen digestion coefficients. The fractional outflow rate of small particles from the rumen (%h) was higher in lambs than in kids and it increased with increasing liveweight. The effect of feedstuffs with low degradability, such as fish meal and formaldehyde treated soybean on the milk yield of sheep and goats was inconsistent and variable. (author). 24 refs, 6 tabs

    This study investigated the influence of alpine grazing on vitamin D (vitD) and bone metabolism in sheep and goats. Two groups of five adult lactating East Friesian milk sheep and Saanen dairy goats were kept on pastures at 2,000 to 2,600 m a.s.l. (SA: sheep alpine; GA: goats alpine) and 400 m a.s.l. (SL: sheep lowland; GL: goats lowland). The animals were milked twice daily and the milk yield was measured. Blood, milk, skin, and forage samples were collected and the left metatarsi were measured with peripheral quantitative computed tomography. The relative humidity and air temperature were recorded and the ultraviolet B (UVB) radiation was measured with a solar meter at both research stations. In addition, animals from the alpine group were equipped with a global positioning system receiver. The UVB radiation was higher at the alpine station (P<0.05) compared to the lowland station. In contrast, both the relative humidity and the air temperature were higher at the lowland station (P<0.04). The group GA produced more milk than GL (P<0.043). No differences in milk production between SA and SL were detected. Only minor differences between the alpine and lowland species groups were found in the total 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D serum concentration and in the 25(OH)D milk concentration. 25-hydroxyvitamin D2 concentration in serum was higher in sheep compared to goats and the 25(OH)D3 concentration in serum increased in all four groups but was higher in the alpine groups during the experiment. In addition, no differences in 7-dehydrocholesterol (7-DHC) concentrations in the skin at high altitude and lowland groups were detectable. However the 7-DHC concentrations in the skin of sheep were less than a tenth of the concentrations in the skin of goats and were nearly not detectable. In both groups SA and SL bone strength index increased during the trial (P=0.043). Bone strength index was lower in GA compared to GL at wk 12 (P=0.047). Mean

    Full Text Available Abstract Background The aim of this study was to investigate possible cross-infection of Dichelobacter nodosus in Norwegian farms practising co-grazing of sheep and cattle. Methods Thirteen farms practising co-grazing of sheep and cattle were included in this descriptive study: five farms with a history of severe ovine footrot (Group I and eight farms with free-stall housing of cattle and signs of mild or no footrot in sheep (Group II. Sampling for PCR detection of D. nodosus was performed from animals in all farms, and clinical claw examination of sheep and cattle was performed in Group II. D. nodosus positive samples were analysed by a multiplex PCR method that detects variants of the fimA gene corresponding to D. nodosus serogroups A through I. Results D. nodosus serogroup A was identified more frequently in sheep from farms with a history of severe footrot (Group I versus from Group II, and in most of the farms with a history of severe footrot there was a coexistence of D. nodosus serogroup A in sheep and cattle. In one farm heel horn erosion and dermatitis emerged in cattle after co-grazing with sheep suffering from severe footrot where D. nodosus serogroup A was detected. Six months later heel horn erosion and dermatitis were still diagnosed, and D. nodosus serogroup A was identified. Out of the 16 D. nodosus positive sheep samples from Group II, ten of the samples were positive by the fimA serogrouping PCR. Among these 10 samples all serogroups except G were detected. All the D. nodosus serogroups detected in sheep were also present in the corresponding cattle herds. Conclusion The clinical findings and the coexistence of the same serogroups in co-grazing sheep and cattle could indicate cross-infection. However, further research including isolation of the bacterial strains, virulence-testing and genetic identification, is needed.

    Full Text Available Serological response to a live commercial vaccine of Peste des petits ruminants (PPR virus administered to sheep and goats in Buchanan, the capital city of Grand Bassa County, Liberia was assessed in view of its importance for effective restocking of small ruminants in the city. Forty-four paired serum samples (pre- and post-vaccination were collected from vaccinated sheep and goats during a nation-wide campaign for food security promotion from March to October, 2011. Sheep and goats were vaccinated against PPR in late April, 2011. Pre-vaccination samples were collected in mid-April, 2011. Post-vaccination samples were collected in mid-October 2011 from the same groups of sheep and goats (6 months after vaccination. Paired serum samples gathered were stored at -4 0C until tested. Competitive Enzyme Linked Immunosorbent Assay (c-ELISA was used to determine antibody levels against PPR virus. Only 34(77.3% out of 44 paired serum samples were adequate in quantity and quality for the test. Test results indicated 27(79.4% out of 44 paired serum samples increased significantly in antibody levels from pre-vaccination to post-vaccination levels that were equal or above threshold of Percentage Inhibition (PI > 50% against PPR vaccine. The importance of these findings to effective veterinary services delivery for the control of this neglected animal disease in Liberia is discussed. The present seroconversion status against PPR virus is considered to be a milestone in rebuilding veterinary services systems in Liberia towards national efforts for food security after prolonged civil war (1989-2003 in the country.

    Full Text Available This study was carried out to describe the ultrasonographic findings in relation to the clinical symptoms of some common ocular conditions in sheep and goats. Fifty animals (32 goats and 18 sheep with different ocular problems were examined. Ultrasonographic examination was performed using a B-mode ocular ultrasound unit, and the structure of the globe was evaluated at a depth of 4-6 cm. Early cases (n=35, 70% showed varying ocular conditions; hypopyon, (n=8, 16%, stromal abscesses, (n=4, 8%, and anterior uveitis (n=23, 46%. Hypopyon appeared clinically as a white or yellowish material in the anterior chamber, and ultrasonographically as a hyperechoic mass in the anterior chamber. Severe iridocyclitis was noticed in acute cases of infectious keratoconjunctivitis (IKC accompanied by blepharospasm, photophobia, excessive tearing and eyelid margin crust formation. Ultrasonographically, the pupil appeared constricted with increased hyperechoic thickening of the ciliary body. In chronic cases of IKC, corneal pigmentation (n=5, 10% and cataract (n=10, 20% were seen. Ultrasonographically the type and degree of cataract were diagnosed. The present study provides an inside view of the inner ocular structures during the course of certain eye diseases where ophthalmoscopic examination is not possible. Our findings, although preliminary, are relevant for the more complete diagnosis of certain external ocular conditions in sheep and goat herds.

    Saliva appears as a defence mechanism, against potential negative effects of tannins, in some species of animals which have to deal with these plant secondary metabolites in their regular diets. This study was carried out to investigate changes in parotid saliva protein profiles of sheep (Ovis aries) and goats (Capra hircus), induced by condensed tannin ingestion. Five Merino sheep and five Serpentina goats were maintained on a quebracho tannin enriched diet for 10 days. Saliva was collected through catheters inserted on parotid ducts and salivary proteins were separated by two-dimensional gel electrophoresis. Matrix-assisted Laser desorption ionization - time of flight (MALDI-TOF) and liquid chromatography tandem mass spectrometry (LC-MS/MS) were used to identify the proteins whose expression levels changed after tannin consumption. Although no new proteins appeared, quebracho tannin consumption increased saliva total protein concentration and produced changes in the proteome of both species. While some proteins were similarly altered in both species parotid salivary protein profile, sheep and goats also presented species-specific differences in response to tannin consumption.

    Weizhe Zhang

    Full Text Available BACKGROUND: Giardia duodenalis is a widespread intestinal protozoan of both humans and mammals. To date, few epidemiological studies have assessed the potential and importance of zoonotic transmission; and the human giardiasis burden attributable to G. duodenalis of animal origin is unclear. No information about occurrence and genotyping data of sheep and goat giardiasis is available in China. The aim of the present study was to determine prevalence and distribution of G. duodenalis in sheep and goats in Heilongjiang Province, China, and to characterize G. duodenalis isolates and assess the possibility of zoonotic transmission. METHODOLOGY/PRINCIPAL FINDINGS: A total of 678 fecal specimens were collected from sheep and goats on six farms ranging in age from one month to four years in Heilongjiang Province, China. The average prevalence of G. duodenalis infection was 5.0% (34/678 by microscopy after Lugol's iodine staining, with 5.6% (30/539 for the sheep versus 2.9% (4/139 for the goats. Molecular analysis was conducted on 34 G. duodenalis isolates based on the triosephosphate isomerase (tpi gene. 29 tpi gene sequences were successfully obtained and identified as assemblages A (n = 4, B (n = 2 and E (n = 23. High heterogeneity was observed within assemblage E at the tpi locus, with five novel subtypes found out of seven subtypes. Two subtypes of assemblage A were detected, including subtype AI (n = 3 and a novel subtype (designated as subtype AIV (n = 1. Two assemblage B isolates were identical to each other in the tpi gene sequences. CONCLUSIONS/SIGNIFICANCE: This is the first report of G. duodenalis infections in sheep and goats in China. The present data revealed the unique endemicity on prevalence, distribution and genetic characterization of G. duodenalis in sheep and goats in Heilongjiang Province. The findings of assemblages A and B in sheep and goats implied the potential of zoonotic transmission.

    Eight Merino sheep (49.4 ± 4.23 kg BW) and 8 Alpine goats (53.2 ± 2.51 kg BW) were used to study the effect of ingestion of quebracho tannins on salivation. Four sheep and 4 goats were individually fed a daily allotment of 20 g DM of alfalfa hay/kg BW (Control). Another 4 sheep and 4 goats were also given 20 g DM of alfalfa hay/kg BW supplemented with 50 g of quebracho/kg DM (Tannin) for a period of 64 d. The saliva secretion from the left parotid gland was collected by insertion of a polyvinyl chloride catheter into the parotid duct and the amount of parotid saliva produced recorded over three 48-h periods on d 1 and 2 (P1), d 31 and 32 (P2), and d 61 and 62 (P3) after the tannin feeding was initiated. The total amount of saliva produced was estimated from rumen water kinetics determined on d 4, d 34, and d 64 of the experiment. Experimental design was completely randomized, with repeated measures on each experimental unit, performing separate analysis for sheep and goats. Parotid saliva production was not affected by the sampling period in either animal species receiving the Control diet. Corresponding values for sheep were 2.04, 2.12, and 2.27 L/d (P = 0.89) and for goats 1.65, 1.79, and 1.86 L/d (P = 0.95). Sheep fed the Tannin diet produced 55, 73, and 107% of the amount of saliva recorded in sheep fed the Control diet on P1, P2, or P3, respectively. Corresponding values in goats were 88, 130, and 134% on P1, P2, or P3, respectively. Estimated total saliva production was not affected (P = 0.50 for sheep and P = 0.97 for goats) by the ingestion of quebracho. There was no difference (P > 0.10) in osmotic pressure, P, Mg, Ca, urea, and protein concentrations in parotid saliva. There were, however, differences in Na and K concentrations in response to the ingestion of quebracho tannins, with Na concentrations increasing (P = 0.05) and K concentrations decreasing (P = 0.04) in sheep saliva and pH increasing (P = 0.05) in goat saliva.

    When a stunning method is being evaluated, it is essential that the animal-handling and restraint methods that are used with it are also examined. This makes it possible to determine the effect of the entire system on animal welfare. Cattle, pigs, and sheep will move easily through the races at a slaughter plant if visual distractions such as reflections on shiny metal, dangling chains, moving equipment, or people up ahead are removed. The most important scientific research on captive bolt, CO2, and electrical stunning methods is reviewed. A common mistake made by people evaluating insensibility is to misinterpret reflexive leg kicks as a sign of return to sensibility. When religious slaughter is being evaluated, the variable of how the animal is restrained must be separated from the variable of slaughter without stunning. Slaughter can be done with a high level of animal welfare. PMID:25387029

    Q fever is a zoonosis caused by the bacterium Coxiella burnetii; domestic ruminants, mainly goats and sheep, are the main source of Q fever outbreaks in humans. From both a public and an animal health perspective, providing reliable prevalence data is extremely relevant for the decision processes by policymakers and food producer organizations. Information on Q fever seroprevalence in small ruminants in Italy is currently incomplete and largely based on reports of reproductive disorders in livestock farms. To estimate animal and flock seroprevalence of C. burnetii in small ruminants (sheep, goats and mixed flocks), a cross-sectional study with a two-stage design was carried out in northwest Italy. Between January and December 2012, sera from 5738 animals (2553 sheep and 3185 goats) belonging to 411 flocks (206 goats, 111 sheep, and 94 mixed flocks) were examined for specific anti-C. burnetii IgG antibodies by a commercial ELISA kit. A questionnaire investigating possible associations between farm management and C. burnetii seropositivity was administered. At the flock level, the overall true seroprevalence adjusted for test sensitivity and specificity was 31.2% (95% confidence interval [CI]: 24.8-37.7). Sheep-farm and goat-farm true seroprevalence was 38.7% (95% CI 25.5-51.9) and 19.5% (95% CI 11.5-27.6), respectively. Interestingly, the true seroprevalence (48.5%; 95% CI 34.7-62.3) was higher in the mixed flocks (sheep and goats). At the animal level, the overall true seroprevalence was 15.9% (95% CI 15.4-16.4). No difference was found between the two species, but the true seroprevalence was significantly higher (χ(2)=7.49; p<0.007) among the goats in mixed flocks (25.7%; 95% CI 24.4-27.1) than the sheep (16.3%; 95% CI 15.1-17.4), suggesting a potential difference in susceptibility between the two species or the result of factors affecting their immune response or related to the livestock management system as the period of exposure to C. burnetii.

  11. Control of the reproductive performance of Chios sheep and Damascus goats: Studies using hormone radioimmuoassays

    International Nuclear Information System (INIS)

    The effects of environment on conception rate and litter size, and of the goat status and age in the preceding season on the time of oestrus appearance were studied. Furthermore, the effect of season of kidding and daily milk production at the occurrence of oestrus on 'days open' was examined. Environmental factors such as temperature, humidity, age of goat or management and feeding could not account for the variation in reproductive behaviour. Ovarian activity monitored for 53 weeks showed that: there was a short period of anoestrus from late March to early July; conventional methods of heat detection are inadequate; there was an irregular heat wave in July which was not followed by repeated cycles; and the regular breeding season for the Damascus goat is in autumn (September to December) and the average length of the cycle is 21 days. The duration of oestrus was studied in parous and non-parous goats following oestrus synchronization with progesterone analogue and PMSG. Overt oestrus appeared 31.1 h (range 24-48 h) after the removal of sponges, and continued for 36-44 h. Its duration was somewhat longer in parous compared to non-parous goats. Serum progesterone levels correlated with oestrus detection by vasectomized males. Milk and blood samples were collected at regular intervals starting three days post-partum to study post-partum anoestrus in Chios sheep. Progesterone assays, carried out using skimmed milk and blood serum, showed that first ovulation occurred approximately within 30 days post-partum. Progesterone levels were much higher in serum than in skimmed milk. It is suggested that Chios sheep have ovulations during the suckling period although overt oestrus could not always be detected by vasectomized males. 50 refs, 8 figs, 7 tabs

    Full Text Available Tracer Inoodle tbin-tail sheep and Kacang goats were used to measure the seasonal changes in gastrointestinal nematodes parasitism i ~'und[, .xillapek .Fodd~ 'ofis in West Java . Each 3 months for 12 months worm-free male sheep (5 and goats (5 about 5 months of age were ~ $Jri~tgldI o% ef- farmer, and managed as part of their flock for 2 months . Animals were then returned to the laboratory and maintained on "`~^taaan-ftwAiet in elevated slatted pens for 3 weeks prior to slaughter. In all trials sheep had higher faecal egg counts than goats . Egg counts were significantly lower during the late dry-early wet season due mainly to lower burdens of Oesophagostomum spp. than at other times of the year. The predominant genera recovered from faecal larval cultures were Haemonchus and Trichostrongylus . At post mortem more than 94 percent of animals were infected with Trichostrongylus colubriformis, T. axei, Haemonchus contortus, Oesophagostomum columbianwn and Strongyloides papillosus . Other species found, in descending order of occurrence, were Cooperia curticei, Trichuris ovis, Bunostornum trigonocephalum, Oesophagostomumn asperum, Capillaria bovis and Gaigena pachycelis. It was concluded that intensity of exposure of both sheep and goats to H contortus, T. axei and C. curticei was similar throughout the year, but that availability of infectioe larvae of T. colubriformis was higher during the dry than the wet season and vise versa for O. columbianum . Sheep had higher burdens of T. Colubrzformis than goats but similar numbers of other species.

    This experiment was carried out on 8 ha of Panicum maximum cv. Tanzania pastures, with rotational grazing consisting of 7 days of occupation and 21 days of rest. Four treatments were evaluated: cattle grazing alone (BOV), sheep grazing alone (OVI), cattle and sheep grazing simultaneously (SIM) and cattle grazing followed by sheep (alternate - ALT). Twenty heifers and 30 male Santa Inês lambs were used. Fecal egg count (FEC) and fecal cultures were carried out. Blood was also collected to examine red and white cell series, total plasma protein (TPP), albumin and hemoglobin. FEC and estimated nematode pathogenicity index in sheep were lower in the SIM treatment. The Haemonchus spp. proportion was higher in isolated grazing systems. For sheep, mixed grazing was shown to reduce endoparasite infection, and SIM was better than ALT. For cattle, no difference between grazing systems was seen. Therefore, simultaneous grazing (sheep and cattle) may be a tool for reducing the need for anthelmintic treatments in sheep. PMID:24473872

    Enterotoxemia was induced in 4 lambs and 4 goat kids by continuous intraduodenal infusion of a whole culture of Clostridium perfringens type D. Clinical signs, hematologic values, biochemical alterations, and postmortem lesions in the lambs and goat kids were compared. The 4 lambs and 4 goat kids died within 25 hours of beginning the infusions. Lesions were not observed in the gastrointestinal tract of the 4 lambs; however, severe hemorrhagic enterocolitis was found in the 4 goat kids. This difference between the lambs and goat kids in the lesions caused by experimentally induced enterotoxemia may explain the discrepancies reported between sheep and goats in clinical signs, response to treatment, and efficacy of vaccination observed in naturally induced enterotoxemia in the 2 species.

    Full Text Available Studies on sheep, goats and terrestrial snails rom a pasture in a north-eastern Bulgarian region have been carried cut. Protostrongylids of 4 genera - Muellerius, Cystocaulus, Protostrongylus and Neostrongylus have been established. The infection extensity in goats is higher than that in sheep while the generic diversity is greater in sheep. In tracing the season dynamics in the parasitic infections of the end hosts it has been established that during the summer the infection extensity is permanently kept in its high values. In the autumn a drop in infection extensity is observed but the amount of the larvae released with faeces is augmented reaching its maximum in November-December. A relative increase in the infection extensity as well as in the larval output is observed in February and solely for the larval output such an increase is recorded in April. Season dynamics in the spread of the different protostrongylid genera in the end hosts and the influence of age and sex on larval output have been traced. The season dynamics of the extensity and intensity of the infection of the snails on the pasture has also been followed up. H. obvia is the intermediate host of greatest importance for the spread of protostrongylidoses in the region under study.

    Full Text Available The Middle East respiratory syndrome coronavirus (MERS-CoV was first recognized in 2012 and can cause severe disease in infected humans. Dromedary camels are the reservoir for the virus, although, other than nasal discharge, these animals do not display any overt clinical disease. Data from in vitro experiments suggest that other livestock such as sheep, goats, and horses might also contribute to viral transmission, although field data has not identified any seropositive animals. In order to understand if these animals could be infected, we challenged young goats and horses and adult sheep with MERS-CoV by intranasal inoculation. Minimal or no virus shedding was detected in all of the animals. During the four weeks following inoculation, neutralizing antibodies were detected in the young goats, but not in sheep or horses.

    The aim of the study was to compare chemical composition and quality attributes of meat between male long fat tailed sheep (n = 17) and Small East African goats (n = 17) existing in Tanzania. Animals of 1.5 to 2 yrs in age and live body weight of 22.59±0.50 kg were purchased from livestock auction markets. Animals were fasted for 18 h and slaughtered according to standard halal procedure. Left carcasses were dissected into muscles, fat and bone and the muscle and fat were mixed together and chemically analysed. Meat quality attributes were measured based on Muscle longissimus thoracis et lumborum excised from right sides of carcasses. Goat carcasses had significant higher (p = 0.0302) moisture content (70.65% vs 66.96%) and lower (p = 0.0027) ether extract (2.49% vs 5.82%) than sheep but there was no significant species differences in protein and ash content. Sheep had lower (p = 0.0157) ultimate pH (5.74 vs 5.88) and higher (p = 0.0307) temperature (3.77°C vs 3.15°C) than goat carcasses. Sheep meat had lower (p = 0.0021) shear force values (29.83 N vs 34.07 N) than goat. Within species, at day 9 of ageing, meat tenderness improved (p = 0.0001) by 44.63% and 34.18% for sheep and goat. Pooled data showed that at d 9 of ageing, meat tenderness improved (p = 0.0001) by 39.25% (from 39.54 N to 24.02 N) compared to tenderness of meat which was not aged at day one of slaughter. The present study demonstrated the differences in chemical composition and quality attributes of meat existing between sheep and goats originated from East Africa. PMID:25049790

  2. Sensitivity of reproductive potential to environmental factors in sheep and goats

    International Nuclear Information System (INIS)

    Ovulation rate, embryo survival, postnatal mortality, interval from parturition to conception, age at first parturition, number of parturitions before culling, and age at culling collectively declineate the ability of a breed to cope with the local environment and management which are often harsh and suboptimal. In tropical and subtropical countries, the reproductive performance of goat and sheep is low and far from their maximum potential. Identification of the main limiting factors and determination of the breed's sensitivity to these factors are essential preliminary steps before choosing the method(s) to improve reproductive performance in such countries.

  5. Phylogenetic analysis of the Capripoxvirus RPO30 gene and its use in a PCR test for differentiating sheep poxvirus from goat poxvirus

    International Nuclear Information System (INIS)

    The Genus Capripoxvirus (CaPV) of the Poxviridae family comprises sheep poxvirus (SPPV), goat poxvirus (GTPV) and lumpy skin disease virus (LSDV) which are responsible for economically important diseases affecting sheep, goats and cattle respectively. To date, there have been no molecular criteria upon which to base strain designation. The complexity of CaPVs host specificity shows the need to develop more reliable tools for CaPVs identification than the current method which is based on the host origin. Previous reports, based on partial or full genome sequencing indicated that CaP viruses are genetically distinct from each other and can be grouped as three different species: SPPV, GTPV and LSDV. In contributing to the creation of more stringent data for geno-typing CaPVs, we have analysed the RPO30 gene of several isolates. The phylogenetic reconstructions have shown that the viruses can be segregated into three different lineages according to their host origins: the SPPV, the GTPV and the LSDV lineages. In addition, a 21-nucleotides deletion found in all individuals within only the SPPV group was exploited to design a classical PCR method to differentiate SPPV from GTPV. This test allows the rapid differential diagnosis of diseases caused by either SPPV or GTPV strains. (author)

    Full Text Available Brucellosis is a disease of animals caused by Brucella species and is transmissible to humans. This study was undertaken to determine the sero-prevalence of the disease in livestock including sheep and goats and camels, in different regions of Abu Dhabi emirate and to identify factors associated with the epidemiology of the disease. A serological study using 6126 blood samples from livestock were obtained from 267 farms (Izaba during the period from January 2009 to December 2010. The Rose Bengal Plate Test and competitive ELISA were used as screening and confirmatory tests, respectively. The overall sero-prevalence of Brucella antibodies was 8.00% and 7.00% detected by the RBPT by c-ELISA respectively. Brucella prevalence was 8.3, 5.9 and 4.7% in Alain, Abu Dhabi and Western region. The prevalence of the disease was higher (8.4% in sheep and goats than (4.4% in camels respectively. The result showed that, the prevalence of brucellosis was significantly higher in females than male (p<0.04 Out of the 267 farms sampled in the study, 147 (55.1% were infected with Brucella There was strong correlation between herd size and prevalence of the disease, very large herds had significantly higher prevalence when compared with small ones. The study revealed light of a size able prevalence among livestock in Abu Dhabi Emirate and the results reflect the necessity of a control program of the disease is needed to be adopted.

    Goats and sheep generally express seasonal variations in their sexual behaviour, spermatogenic activity (from moderate decrease to very low sperm production), gamete quality (variations in fertilization rates and embryo survival), ovulation frequency (presence or absence of ovulation), and ovulation rate (number of eggs shed per ovulation period). This induces seasonal availability of derived, fresh animal products (meat, milk and cheese) because of a more or less marked seasonal distribution of births. A complex combination of an endogenous circannual rhythm driven and synchronized by light and melatonin, which controls the pulsatile activity of GnRH neurons in the preoptic-mediobasal hypothalamus, is responsible for these changes. Dramatic and long-term neuroendocrine changes, involving different neuromediator systems and neuronal plasticity, have been shown to play a role in these processes. A strong variability between breeds exists in both species regarding the dates of onset and end of the breeding season, with a gradient of seasonality from southern to northern latitudes. Within a breed, seasonal traits are heritable; thus, genetic selection could be one way to decrease seasonality in sheep and goats in the future. PMID:24417198

    The Echinococcus granulosus tapeworm is responsible for cystic echinococcosis (CE), a zoonotic disease with worldwide distribution. The life cycle of the parasite is mainly domestic and takes place between dogs and livestock species. A slaughterhouse survey was conducted in 2012 in the Republic of Moldova in order to estimate the prevalence of CE. A total of 1525 cattle, 5580 sheep and 12,700 pigs were surveyed. No CE infection was observed in pigs, while prevalence was estimated at 59.3% in cattle and 61.9% in sheep. Infection was significantly higher in animals raised in private households than in those from collective farms. The frequency of infection increased with age in both species. In cattle and in sheep, infection of both the liver and lungs was the most common, while infection in the lungs only was much less frequent. Farm type appears to be an important factor in CE infection in Moldova, due to the extensive farming and the home-slaughtering undertaken in the majority private sector, despite a high prevalence of CE also recorded in the public sector. The low fertility of cysts in cattle (1.1%) compared to sheep (47.6%) confirmed the maintenance of E. granulosus sensu stricto in a dog-sheep life cycle which excludes cattle. Further studies are needed to obtain a complete overview of the parasite's epidemiology in its intermediate and definitive hosts, in order to implement control and preventive measures, with specific attention given to farms in the private sector.

    Three field cases of ill-thrift, hepatic lipodystrophy and low tissue levels of vitamin B12 in young angora cross goats are reported. The cases meet the criteria for the diagnosis of white liver disease (WLD) described for sheep. The hypothesis that WLD is a metabolic consequence of cobalt/vit B12 deficiency in sheep and goats on a diet rich in propionate is developed, together with possible reasons for its occurrence in these species but not in cattle or red deer.

  11. Feed selection and radiocaesium intake by reindeer, sheep and goats grazing alpine summer habitats in southern Norway

    International Nuclear Information System (INIS)

    Radiocaesium concentrations (137Cs) were measured in extrusa from oesophageally fistulated sheep, goats and reindeer grazing alpine summer vegetation in Griningsdalen, Southern Norway in the period 1987-1989. The experiments with sheep and goats were conducted in different sub-alpine areas. The reindeer were, in addition, grazed in three areas in the low alpine zone. Grazing bouts lasted for 10-20 min and bite selections were recorded every 15 s through the grazing bout. Reindeer and goats had the most diverse food selection whereas sheep fed mainly on grasses, forbs and to some extent, on leaves of willow. The reindeer extrusa had the highest radiocaesium activity, apparently to a large extent caused by intake of lichens in areas where this type of plants were present. Depending on the type of vegetation in the grazed areas the transfer of radiocaesium from soil to grazed vegetation (Bq kg-1 dry extrusa/Bq m-2 soil) was estimated to 0.02-0.04 in sheep, 0.02-0.05 in goats and 0.02-0.43 in reindeer for 1987.

    Full Text Available Peste des petits ruminants (PPR is an acute febrile viral disease of sheep and goats characterized by mucopurulent nasal and ocular discharge, necrotizing and erosive stomatitis, enteritis and pneumonia. The disease is endemic in Pakistan and causes huge economic losses due to high rates of mortality and morbidity in infected sheep and goats. In the present study, 660 serum samples of sheep and goat were collected from 24 districts of Punjab Province of Pakistan. Competitive Enzyme Linked Immunosorbant Assay (cELISA was used to detect the presence of antibodies in the serum against PPRV. Findings suggested that the sero-positive cases were significantly higher in sheep than in goats (51.29 versus 39.02%; P=0.002. The overall sero-prevalence of PPRV in small ruminants was 43.33%. Highest prevalence (35.71-100% was observed in Southern districts, while no antibodies were found in serum from some of Northern and Eastern districts of the Punjab Province.

    Ingestion of small amounts of some types of condensed tannins (CTs) by ruminant livestock can provide nutritional, environmental and economic benefits. However, practical methods are needed to make these tannins more available to ruminant livestock. Results from previous trials with crude quebracho and black wattle tannin indicated that cattle and/or sheep would not preferentially drink water containing these tannins. Therefore, we conducted preference trials to determine if cattle and sheep would learn to prefer water containing purified grape seed tannin (GST) that provided up to 2% of their daily dry matter (DM) intake. After gradual exposure to increasing amounts of this tannin in water during a pre-trial period, five adult ewes and five yearling heifers fed lucerne (Medicago sativa) pellets (19% CP) were offered water and several concentrations of GST solutions for either 15 (sheep trial) or 20 days (cattle trial). We measured intake of all liquids daily. Concentrations of blood urea were also measured for heifers when they drank only tannin solutions or water. Both sheep and cattle developed preferences for water with GST in it over water alone (P < 0.01) although this preference appeared earlier in the trial for sheep than for cattle. For the sheep, mean daily intake of water alone and all tannin solutions (in total) was 0.6 and 6.1 l, respectively. For the cattle, mean daily intake of water and all tannin solutions in total was 21.8 and 20.6 l, respectively, in the first half of the trial and 10.8 and 26.1 l, respectively, in the second half of the trial. Compared with the other tannin solutions, both sheep and cattle drank more of the solution with the highest tannin concentration (2% of daily DM intake as GST) than of water on more trial days (P < 0.05). Ingestion of water with the highest concentration of GST reduced blood plasma urea concentration in the cattle by 9% to 14% (P ≤ 0.10) compared with ingestion of water alone. Results from the trials

    This cross-sectional study aimed to estimate the seroprevalence of Brucella infection among sheep and goats on small-scale farms in a peri-urban area of Tajikistan and identify factors associated with seropositivity. The study population was 667 female sheep and goats >6 months of age from 21 villages in four districts surrounding the capital city, Dushanbe. Individual blood samples were collected during October and November 2012 and analysed with indirect enzyme linked immunosorbent assay (ELISA). Positive samples were confirmed with competitive ELISA. To identify factors associated with seropositivity at an individual level, a generalised linear mixed model was applied to account for clustering of individuals within villages and districts. The true individual seroprevalence was 6.7 % and ranged from 1.0 to 15.6 % between the four districts. Fourteen villages had at least one seropositive sheep or goat, resulting in apparent prevalence of 67 % at village level. The seroprevalence at individual level was significantly lower in Rudaki district (odds ratio (OR) = 0.1; 95 % confidence interval (CI) 0.03-0.4) and Varzob district (OR = 0.3; 95 % CI 0.09-0.8) than in Vahdat district. Sheep were more likely than goats to be seropositive (OR = 2.7; 95 % CI 1.3-5.5). Increasing age was significantly associated with seropositivity (OR = 1.4; 95 % CI 1.2-1.6). These results indicate high prevalence of Brucella infection among sheep and goats in the peri-urban area of the capital city in Tajikistan. Given the dense human population in such areas, this could constitute a threat to public health, besides causing significant production losses. PMID:26779709

    Limited prior evidence suggests that 5′-nucleotidase, an ectoenzyme principally located in the Malpighian tubules of the tick Rhipicephalus (Boophilus) microplus, could be an effective antigen in an anti-tick vaccine. To assess this, recombinant 5′-nucleotidase was expressed in Escherichia coli and used in vaccination trials with both sheep and cattle. Vaccinated sheep were challenged with freshly moulted adult ticks. Those with high titres of anti-nucleotidase antibodies showed significant p...

    Livestock are known contributors to stream pollution. Numbers of fecal streptococci and Escherichia coli in manure naturally deposited by livestock in the field are needed for activities related to bacterial source tracking and determining maximum daily bacterial loading of streams. We measured populations of fecal streptococci and E. coli in fresh and dry manure from cattle (Bos taurus L.), horses (Equus caballus L.), and sheep (Ovis aires L.) on farms in southern Idaho. Populations of indicator bacteria in dry manure were often as high as that in fresh manure from horse and sheep. There was a 2 log10 drop in the population of fecal coliform numbers in dry cattle manure from cattle in pastures but not from cattle in pens. Bacterial isolates used in source tracking should include isolates from both fresh and dry manure to better represent the bacterial source loading of streams. PMID:16333344

    In dairy field, one of the most common frauds is the adulteration of higher value types of milk (sheep's and goat's) with milk of lower value (cow's milk). This illegal practice has an economic advantage for milk producers and poses a threat for consumers' health because of the presence of hidden allergens as, for example, cow milk proteins, in particular, α(s1)-casein and β-lactoglobulin. The urgent need of sensitive techniques to detect this kind of fraud brought to the development of chromatographic, immunoenzymatic, electrophoretic and mass spectrometric assays. In the current work, we present a fast, reproducible and sensitive method based on the direct matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) MS analysis of milk tryptic digests for the detection of milk adulteration by evaluating specie-specific markers in the peptide profiles. Several pure raw and commercial milk samples and binary mixtures containing cows' and goats', cows' and sheep's and goats' and sheep's milk (concentrations of each milk varied from 0% to 100%) were prepared, and tryptic digests were analyzed by MALDI-TOF MS. The use of the new MALDI matrix α-cyano-4-chlorocinnamic acid allowed to detect cow and goat milk peptide markers up to 5% level of adulteration. Finally, from preliminary data, it seems that the strategy could be successfully applied also to detect similar adulterations in cheese samples. PMID:22972782

  20. 125I-labeled protein A as a general tracer in immunoassay: suitability of goat and sheep antibodies

    International Nuclear Information System (INIS)

    The immunoassay method in which 125I-labeled staphylococcal Protein A ([125I]PA) serves as a general tracer has been extended to include goat and sheep IgG antibodies. Goat and sheep IgG normally do not react significantly with PA. However, once IgG antibody is bound to immobilized antigen or hapten, binding of [125I]PA is enhanced markedly. Binding efficiencies of [125I]PA to immune complexed goat anti-human IgM, human IgE, methotrexate and sheep anti-IgE were determined and compared quantitatively to rabbit IgG with the corresponding specificity. Immunoassays were developed based on the inhibition of [125I]PA binding as a measure of antibody inhibition by fluid-phase homologous ligand. Goat antibody to the monovalent hapten methotrexate behaved anomalously: for each concentration of IgG tested, there was an optimal amount of methotrexate beads that gave maximum binding of [125I]PA. In the other immune systems, for each antibody concentration maximum binding of tracer was a function only of the amount of immobilized anitgen added. In contrast to the results obtained with solid-phase antigen, solutions containing antibody and amounts of antigen ranging from large antigen excess to antibody excess failed to react significantly with PA or [125I]PA.

    Orf virus was clinically diagnosed from different field cases of sheep and goat in Hawamdia, Giza, Egypt during the summer 2006. Skin scabs were collected and used for virus isolation, electron microscopy, PCR and sequencing for confirmation, and differential diagnosis. The aetiological virus was fruitfully isolated on the chorio-allantoic membrane of SPF embryonated chicken eggs indicated by expressing the characteristic pock lesions of Poxviridae family. Electron microscopy examination exposed negatively stained oval-shape virus particles trait for members of the genus Parapoxvirus. A 392 bp fragment of the late transcription factor (VLTF-1) gene of orf virus was amplified by PCR from the DNA extracted from the isolates. Phylogenetic analysis revealed 99% identity with other orf virus strains reported worldwide. Selection and processing of clinical specimens and PCR assay applied in this endeavor, presented a reliable laboratory diagnostic tool for orf infections and first molecular characterization of Egyptian orf isolates.

    Small ruminants infected with scrapie show a large range of often unspecific clinical symptoms. The most-often described signs, locomotion, sensibility and behavioural disorders and emaciation, rarely occur together, and cases have been described in which only one of those signs was detectable.Thus, formulating a well-circumscribed definition of a clinical suspect case is difficult. Most animals with CNS-effecting diseases such as listeriosis, polioencephalomacia, cerebrospinal nematidiasis and enterotoxemia will, in a thorough neurological examination, show at least some scrapie-like symptoms. Among the 22 neurological field cases examined in this study, a goat with cerebral gliomatosis and hair lice showed the closest similarity to clinical scrapie. The unilateral deficiency of the cerebral nerves has potential as an clinical exclusion criterion for scrapie. However, the laboratory confirmation--or exclusion--of scrapie remains important. It thus needs to be realized that a consistent and thorough examination of neurologically diseased small ruminants (including fallen stock) is the backbone of a good surveillance system for these diseases. This should be a motivation for submitting adult sheep and goats for neuropathological examination. PMID:16259408

    OBJECTIVE To evaluate the use of a percutaneous transabdominal catheter (PTC) for urinary bladder drainage in goats, sheep, and potbellied pigs with obstructive urolithiasis. DESIGN Retrospective case series. ANIMALS 43 goats, 10 sheep, and 16 potbellied pigs (all males) with obstructive urolithiasis evaluated at the University of California-Davis Veterinary Medical Teaching Hospital. PROCEDURES Medical records of goats, sheep, and potbellied pigs examined because of obstructive urolithiasis from January 2000 through December 2014 were reviewed. Records of animals for which a standard PTC had been placed into the urinary bladder as part of disease management were selected. Data were collected regarding signalment, complications associated with PTC placement, and duration of PTC placement prior to removal. RESULTS 42 of 43 goats, 5 of 10 sheep, and all potbellied pigs were castrated. Median (range) duration of PTC placement was 2 (1 to 4) days for goats, 1 (1 to 4) day for sheep, and 1 (1 to 3) day for potbellied pigs. Complications associated with PTC placement included blockage of the catheter by urine sediment, perforation of the cecum, and migration of the catheter out of the urinary bladder. CONCLUSIONS AND CLINICAL RELEVANCE Placement of a PTC into the urinary bladder allowed for effective stabilization of goats, sheep, and potbellied pigs with obstructive urolithiasis while acid-base and electrolyte imbalances were corrected. Use of a PTC should be considered for urinary bladder drainage during medical management or prior to surgical management of obstructive urolithiasis for these species. PMID:27172346

    Sarcocystis spp. are cyst-forming coccidia that infect numerous animals species, including several livestock species. Despite the importance of sheep and goat production in Brazil, little it is known about the Sarcocystis species that infect small ruminants in the country and their potential impact on meat condemnation due to the presence of macroscopic cysts of the parasite. The aims of the present study were to determine the frequency of infection by Sarcocystis spp. in goats and sheep intended for human consumption in Bahia State, Brazil, as well as to identify the parasite species in selected samples. The entire tongue, esophagus, and heart were collected from 120 goats and 120 sheep. Tissues were examined for Sarcocystis spp. by macroscopic evaluation, light microscopy, electron microscopy, and molecular tests. Microscopic cysts of Sarcocystis spp. were detected in 95.8 % of sheep and 91.6 % of goats. Using either transmission electron microscopy or partial sequencing of the 18S region of the ribosomal DNA (rDNA) for species identification, Sarcocystis tenella and Sarcocystis arieticanis were observed in sheep and Sarcocystis capracanis in goats. Macroscopic cysts were not detected in the analyzed samples. We concluded that goats and sheep destined for human consumption in Bahia possess high frequencies of Sarcocystis infection. Carcass condemnation due to Sarcocystis macrocysts seems to be rare in the studied region. S. arieticanis and S. capracanis were confirmed for the first time by electron microscopy or by molecular tests in small ruminants from Brazil. PMID:26786832

    Limited prior evidence suggests that 5'-nucleotidase, an ectoenzyme principally located in the Malpighian tubules of the tick Rhipicephalus (Boophilus) microplus, could be an effective antigen in an anti-tick vaccine. To assess this, recombinant 5'-nucleotidase was expressed in Escherichia coli and used in vaccination trials with both sheep and cattle. Vaccinated sheep were challenged with freshly moulted adult ticks. Those with high titres of anti-nucleotidase antibodies showed significant protection against tick infestation, although protection was less than that found with the previously characterized antigen, Bm86. Cattle were vaccinated, in separate groups, with 5'-nucleotidase, Bm86 and both antigens combined. Cattle, as the natural host, were challenged with larval ticks. Although Bm86 showed typical efficacy, no significant protection was seen in cattle vaccinated with 5'-nucleotidase. Cattle receiving a dual antigen formulation were no better protected than those receiving Bm86 alone. One possible reason for the difference between host species, namely antibody titre, was examined and shown to be an unlikely explanation. This demonstrates a limitation of using a model host like sheep in vaccine studies. PMID:20070827

    Full Text Available The aim of this study was to determine the hematological and serological changes in experimentally infected sheep and goats and to validate use of Real time reverse transcriptase PCR analysis in diagnosing PPRV in Kenya. In this study, five sheep and five goats aged 3-6 months and of different sexes were experimentally infected with lineage III PPR virus. Further, two goats and two sheep that were confirmed using c-ELISA kit to be free from PPR were used as controls. Hematological examination of infected animals revealed a modest decrease in lymphocyte counts (L and a slight increase in Neutrophils (N and White Blood Cell Count (WBC in goats. Parameters of the erythron apart from an increase in HB were unremarkable in goats. An increase in White Blood Cells (WBC, Neutrophilia, lymphopaenia and relative change in red blood cells (RBCs parameters were consistently observed in infected sheep. Serology revealed the presence of antibodies against PPRV by 10th day post infection with both goats and sheep showing mean competition percentage of 41.10 ±10 and 40.768 ±5.26, respectively. Antibodies against PPRV continued to rise by day 14 where both goats and sheep showed a mean competition percentage of 29.77 ±4.98 and 22.51 ±6.69, respectively. Real-time -PCR revealed positive amplification in ocular swabs, mesenteric lymph nodes, intestines and in lungs. Results of this study indicated that infection with PPR in sheep and goats provide valuable data about hematological and serological findings that can be used for diagnosis of PPR. Samples of choice for real-time PCR diagnosis for PPR are ocular swabs, mesenteric lymph nodes, intestines and lungs.

    Since the discovery of Scrapie Syndrome in sheep and goats in 1730, there emerged a series of diseases such as Creutzfeldt-Jakob disease, kuru disease and mad cow disease etc. In the research of kuru disease, the American scientist D. Carlteton Gajdusek found a new virus without the characteristic of DNA and RNA, which was awarded the Nobel Prize in physiology in 1976. Since then another American scientist, Stanley B. Prusiner, found a new virus-prion, taking protein as the genetic medium, which was awarded the Nobel prize in physiology and medicine in 1997. The discovery of prion is a great landmark in the research of life science, which laid a theoretical foundation for people to conquer a series of diseases such as Scrapie syndrome in sheep and goats, Creutzfeldt-Jakob disease, kuru disease and mad cow disease etc. PMID:19930927

    It has been suggested that goats (typical browser) are better adapted to digest tannin-rich diets than sheep (typical grazer). To evaluate this, Bonga sheep and Kaffa goats were used in a 2 × 3 randomized crossover design with two species, three diets, and three periods (15-day adaptation + 7-day collection). The dietary treatments consisted of grass-based hay only (tannin-free diet = FT), a high-tannin diet (36% Albizia schimperiana (AS) + 9% Ficus elastica (FE) + 55% FT (HT)), and HT + polyethylene glycol 6000 (PEG). Animals were individually fed at 50 g dry matter (DM)/kg body weight (BW) and had free access to clean drinking water and mineralized salt licks. Nutrient intake, apparent nutrient digestibility, nutrient conversion ratios, and live weight changes were determined. Condensed tannin concentrations in AS and FE were 110 and 191 g/kg DM, respectively. Both sheep and goats ate 47% more of HT than FT, and dry matter intake further increased by 9% when PEG was added, with clear difference in effect size between goats and sheep (P effects of the tannin-rich diet and PEG addition were similarly positive for DM digestibility between sheep and goats, but crude protein (CP) digestibility was higher in HT + PEG-fed goats than in sheep fed the same diet. However, PEG addition induced a larger improvement in growth performance and feed efficiency ratio in sheep than in goat (P effect size in sheep. PMID:26519145

In sheep milk samples collected in 2013, 8 out of 172 (4.6% were contaminated by AFM1 with a concentration (mean±SD of 12.59±14.05 ng/L. In one bulk tank milk sample 58.82 ng/L AFM1 was detected, exceeding the EU limit. In none of goat milk samples analysed from 2010 to 2012 AFM1 was detected. In 2013, 9 out of 66 goat milk samples (13.6% showed an AFM1 concentration of 47.21±19.58 ng/L. Two of these samples exceeded the EU limit, with concentrations of 62.09 and 138.6 ng/L. Higher contamination frequency and concentration rates were detected in bulk tank milk samples collected at farm than in bulk milk truck or silo samples, showing a dilution effect on AFM1 milk content along small ruminants supply chain. The rate and levels of AFM1 contamination in sheep and goat milk samples were lower than other countries. However, the small number of milk samples analysed for AFM1 in Sardinia Region in 2005-2013 give evidence that food business operators check programmes should be improved to ensure an adequate monitoring of AFM1 contamination in small ruminant dairy chain.

    This study aimed to test whether the digestive and metabolic characteristics of pseudo ruminants provide superior ability to utilise low-quality diets compared to true ruminants. A total of 18 mature, non-pregnant, non-lactating female animals, including six llamas (Lama glama), six Danish Landrace goats and six Shropshire sheep, were used in a crossover design study. The experiment lasted for two periods of three weeks. Half of the animals were fed either high-quality grass hay (HP) or low-quality grass seed straw (LP) during each period. Animals were placed in metabolic cages during the last 5 d, and gaseous exchange was measured by open-circuit indirect calorimetry for 22 h. Metabolisable energy for maintenance (MEm) and fasting energy expenditure (FEExp) were estimated by regression approach. Dry matter (DM) intake per kg(0.75) was substantially reduced in llamas and sheep, but not in goats, on the LP compared to HP diet. Llamas had lower daily energy expenditure (324 kJ · kg(-0.75)) than sheep (416 kJ · kg(-0.75)) and goats (404 kJ · kg(-0.75)) on the LP diet. Llamas in comparison with sheep and goats had lower methane emission (0.83 vs 1.34 and 1.24 l · d(-1) · kg(-0.75), p < 0.05), lower MEm (328 vs 438 and 394 kJ · d(-1) · kg(-0.75), p < 0.05) and lower FEExp (246 vs 333 and 414 kJ · d(-1) · kg(-0.75), p < 0.05), respectively. In conclusion, llamas had lower basal metabolic rate and hence maintenance requirements for energy. PMID:24870266

    Full Text Available Abstract Background The Swedish salmonella control programme covers the entire production chain, from feed to food. All salmonella serotypes are notifiable. On average, less than 20 cases of salmonella in food-producing animals are reported every year. In some situations, the cases would be expected to cluster geographically. The aim of this study was to illustrate the geographic distribution of the salmonella cases detected in pigs, cattle and sheep. Methods Data on all herds with pigs, cattle and sheep found to be infected with salmonella during the time period from 1993 to 2010 were obtained from the Swedish Board of Agriculture. Using the ArcGIS software, various maps were produced of infected herds, stratified on animal species as well as salmonella serotype. Based on ocular inspection of all maps, some were collapsed and some used separately. Data were also examined for temporal trends. Results No geographical clustering was observed for ovine or porcine cases. Cattle herds infected with Salmonella Dublin were mainly located in the southeast region and cattle herds infected with Salmonella Typhimurium in the most southern part of the country. Some seasonal variation was seen in cattle, but available data was not sufficient for further analyses. Conclusions Analyses of data on salmonella infected herds revealed some spatial and temporal patterns for salmonella in cattle. However, despite using 18 years' of data, the number of infected herds was too low for any useful statistical analyses.

The skull of five sheep weighing 45-50 kg, three goat weighing 50-60 kg and five roe deer weighing 20-25 kg were used in this study. Macerations of the cranium were performed by the boiling method. The skull of the roe deer was notably similar to that of sheep with the presence of external lacrimal fossa, and to the goat with due to the presence of two points (lateral and medial on the septal process and a significant fissure formed between the nasal, lacrimal, frontal and maxillary bones. In addition to these similarities, the formations which were specific to the roe deer were structures such as the number and position of the lacrimal foramen and presence of an uncertain muscular tubercle in the basilar portion of the occipital bone. In addition, the craniometric parameters specific to the roe deer’s skull were determined as the zygomatic, interorbital, neurocranium and nasal lengths.

    A survey of Coxiella burnetii infection (Q fever) in sheep flocks and goat herds in Great Britain was undertaken. A total of 5791 sheep (384 flocks) and 522 goats (145 herds) were examined for C. burnetii antibodies using an ELISA. Overall, 53 sheep (37 flocks), and four goats (four herds), tested positive. Estimates of individual animal, between-flock/-herd and within-flock/-herd crude prevalences were 0·9%, 10·2% and 9·0%, respectively, for sheep, and 0·8%, 3% and 26·3%, respectively, for goats. With sheep, the likelihood of an animal testing positive increased with total flock size (P = 0·002) and number of breeding ewes in the flock (P = 0·021). It also increased with number of goats within a 10 km radius (P = 0·038). There was no evidence for spatial clustering of positive herds above that expected by chance alone. No analysis of risk factors was attempted for goats because of the paucity of positives. PMID:25990008

    Full Text Available This study is carried out with five Turkish shepherd dog (Canis familiaris, five curly sheep (Ovis aries and five native hair goats (Capra hircus which were adult and in different gender, macroanatomical, subgross and comprehensive research of sensible nerves (n. innervating shoulder joint capsule was aimed. The shoulder joint capsule was found to be innervated by axillary and suprascapular nerves in Turkish shepherd dog, curly sheep and native hair goats in macroscopic and subgross analysis. The articular branch of axillary nerve was detected to generally terminate in joint capsule with 3 branches from caudolateral and suprascapular nerve was detected to terminate in joint capsule with 1 branch from lateral. In conclusion, number of the articular branches was found to be more in Turkish shepherd dogs and native hair goats compared to curly sheep. These differences were considered to be related to stated two species being more athletic and faster than curly sheep.

    Full Text Available Dairy goat and sheep farms suffer severe economic losses due to intramammary infections, with S. aureus representing the main cause of clinical mastitis in small ruminants. In addition, S. aureus contamination of goat and sheep milk may cause staphylococcal food poisoning, as many traditional caprine and ovine milk products are not subjected to pasteurization. Data on virulence and antimicrobial resistance genes, as well as on the clonality of S. aureus detected in goat and sheep milk is scarce. Therefore, it was the aim of this study to determine i spa types and clonal complexes and ii virulence and resistance gene profiles of S. aureus isolated from goat and sheep milk. A total of 162 milk samples from sheep and goats presenting signs of an intramammary infection and 104 bulk milk samples were collected. While low prevalence rates of S. aureus were detected on single animal level, 46% of the bulk tank milk samples from small ruminants were positive for S. aureus. All isolates were spa typed and clonal complexes and virulence and resistance gene patterns were determined using a DNA microarray. Data from 49 S. aureus isolates was included in the statistical analysis and the construction of a SplitsTree. The analyzed isolates could be assigned to eleven clonal complexes, with the large majority of goat and sheep isolates being assigned to CC130 and CC133. The findings of this study suggest that S. aureus shows pronounced adaptation to small ruminants in general, but not to sheep or goats in particular. Although some common characteristics among S. aureus from caprine, ovine, and bovine milk samples were observed, S. aureus from small ruminants seem to form a distinct population. As 67% of the detected S. aureus strains exhibited at least one enterotoxin gene, many caprine or ovine raw milk products may be contaminated with low levels of enterotoxigenic S. aureus, stressing the importance of strict maintenance of the cold chain.

    Goat and sheep milk is consumed by human populations throughout the world; as a result, it has been proposed as an alternative, nutrient-rich milk to feed infants allergic to cow's milk. Unfortunately, potentially harmful bacteria have not been thoroughly tested in goat or sheep milk. Listeria monocytogenes is a harmful bacterium that causes adverse health effects if ingested by humans. The purpose of this study was to estimate the prevalence and characterize the phenotype, genotype, virulence factors, biofilm formation, and antibiopotential of Listeria isolated from the milk of goat and sheep. Udder milk samples were collected from 107 goats and 102 sheep and screened for mastitis using the California mastitis test (CMT). Samples were then examined for the presence of pathogenic Listeria spp; if detected, the isolation of pathogenic Listeria (L. monocytogenes and Listeria ivanovii) was completed using isolation and identification techniques recommended by the International Organization for Standards (ISO 11290-1, 1996), in addition to serological, in vitro and in vivo pathogenicity tests. The isolates were subjected to PCR assay for virulence associated genes (hlyA, plcA, actA, and iap). Pathogenic Listeria spp. were isolated from 5·6% of goat and 3·9% sheep milk samples, with 33·3 and 25% of these selected samples respectively containing L. monocytogenes. The results of this study provide evidence of the low-likelihood of contamination leading to the presence of L. monocytogenes in raw goat and sheep milk; however, this study also confirmed a strong in vitro ability for biofilm formation and pathogenic capability of L. monocytogenes if discovered in the milk. L. monocytogenes may be present in goat and sheep milk and in order to reduce the exposure, hygienic milking conditions must be employed for the milk to be considered a safe alternative for human consumption.

    A cross-sectional study was carried out on sheep and cattle slaughtered at a New Zealand abattoir from September to November 2010 to investigate the supplier-specific shedding rate, renal carriage rate and seroprevalence of leptospires. In the 2008/2009 season, this abattoir experienced three human leptospirosis cases from 20 staff, of which two were hospitalized. Urine, kidney and blood samples were collected from carcasses of 399 sheep (six suppliers, 17 slaughter lines) and 146 cattle (three suppliers, 22 slaughter lines). The urine and kidney samples were tested by quantitative real-time PCR (qPCR), while serum samples (from coagulated blood samples) were tested by microscopic agglutination test (MAT). In total, 27% (73/274; 95% CI: 18-37) of urine samples tested positive by qPCR. Species-specific shedding rates (prevalence of positive urine qPCR) were 31% (95% CI: 17-48) for sheep and 21% (95% CI: 14-30) for cattle. For 545 kidney samples tested, 145 were qPCR positive (27%; 95% CI: 17-39). The average prevalence of kidney qPCR positivity was 29% (95% CI: 17-45) for sheep and 21% (95% CI: 15-28) for cattle. Three hundred and thirty of 542 sampled sheep and cattle had antibodies against Leptospira borgpetersenii serovar Hardjobovis (Hardjobovis) and/or Leptospira interrogans serovar Pomona (Pomona), based on reciprocal MAT titre ≥1 : 48 (overall seroprevalence of 61%; 95% CI: 48-73). Seroprevalence was 57% (95% CI: 40-72) for sheep and 73% (95% CI: 59-83) for cattle. Among the seropositive animals, 41% (70/170; 95% CI: 30-54) were shedding (tested positive by urine qPCR) and 42% (137/330; 95% CI: 30-54) had renal carriage (tested positive by kidney qPCR). Some risk management options for abattoirs or farms to prevent human leptospirosis infections include vaccination of maintenance hosts, the use of personal protective equipment, and the application of urine qPCR to detect shedding status of stock as surveillance and as an alert.

    . A outra cabra pariu um cabrito que morreu imediatamente após o parto, sem ter ingerido colostro. Estes resultados sugerem que o princípio ativo da planta foi eliminado pelo leite em doses tóxicas. Recomendamse medidas de controle da intoxicação.Mascagnia rigida is the most important toxic plant for cattle in the Northeastern region of Brazil, causing sudden death during exercise. The objectives of this research were to report three outbreaks of poisoning by M. rigida in sheep and one in goats in the semiarid of the state of Paraíba, to reproduce experimentally the disease, and to determine if the active principle of the plant is eliminated through the milk. The outbreaks occurred at beginning of the raining season, when the plant sprouts ahead other forages, or after the end of the raining season, when M. rigida stayed green and other forages had dried. In the experimental reproduction of the poisoning doses of 10 and 20g of M. rigida per kg body weight from two different regions were lethal to 3 goats and 3 sheep. One goat that ingested 20g/kg and a sheep that ingested 10g/kg recovered. Two sheep and two goats that ingested 5g/kg had mild clinical signs and recovered. Clinical signs of experimental and spontaneous cases were ingurgitation of the jugular veins, reluctance to move, sternal recumbence, incoordination, respiratory distress, depression, instability, and muscular tremors. Death occurred after a clinical manifestation period of about 4 min to 27h40min. The main lesions were pulmonary edema and vacuolization and necrosis of epithelial cells in some renal tubules. To test if the active principle of M. rigida causes sudden deaths in newborn lambs and kids, 2g/kg of the plant were given daily to two goats and five sheep in the 15 days previous to parturition. One sheep aborted two lambs, 5 days before parturition. The four lambs of the other four sheep ingested the colostrum without problems. The kid from one goat ingested the colostrum and died

    Full Text Available Uptake of different heavy metal residues including cadmium (Cd, chromium (Cr, nickel (Ni, led (Pb, arsenic (As, and mercury (Hg were determined in goat and cattle milk collected from two areas, each consisted of three sites. Area 1 was selected in the North-East and Area 2 in the North-West of Faisalabad city along the main sewerage drains. Levels of Cd, Cr, Ni, Pb, As and Hg in the milk of goat and cattle were higher than the most reported values in the literature. The levels of heavy metal residues in the milk of cattle from Area 1 were higher than those present in cattle milk from Area 2. However, in case of goat milk the residual values from Area 1 and Area 2 were non-significantly different. It was concluded that the levels of Cd, Cr, Ni, Pb, As and Hg in the milk of goat and cattle were higher than reported values in the literature.

  9. Water requirements and metabolism of Egyptian sheep and goats as affected by breed, season and physiological status

    International Nuclear Information System (INIS)

    Water requirements and metabolism and some physiological and blood characteristics were studied in dry non-pregnant Barki and Rahmani ewes and in Baladi goats during spring, summer and winter seasons. The Rahmani sheep showed greater thermal discomfort than the Barki during the summer season. Pregnancy was associated with a significant increase in body weight and a decline in PCV and total serum protein, and these changes were greater in goats than in sheep. They were accompanied by significant increases in TBW and WTR. All these changes were more pronounced during late pregnancy than during mid-pregnancy, although the effect of stage of pregnancy on TBW did not occur in the Barki ewes. The pregnancy induced changes in total protein and WTR were greater in spring, while those in TBW were greater in winter. The above parameters also showed similar changes during lactation (particularly during early lactation), but lactating animals showed a decrease instead of an increase in body weight. Goats showed greater reductions in body weight, PCV and water t1/2 and greater increases in WTR than sheep during the spring season. Withdrawal of drinking water for four days caused a reduction in body weight, blood glucose and plasma T3 and T4, and an increase in PCV, total serum protein and plasma osmolality. Plasma aldosterone increased slightly during dehydration but increased markedly during the rehydration period, particularly in the Rahmani sheep during the summer season. The above parameters changed similarly when the animals were starved for four days (feed but not water was withheld), but total serum protein showed a decrease instead of an increase. Changes during dehydration were more pronounced in summer, while those during starvation were greater in winter. 32 refs, 4 figs, 2 tabs

    Begoña M. Jugo

    2013-08-01

    Full Text Available Small ruminant lentiviruses (SRLV are members of the Retrovirus family comprising the closely related Visna/Maedi Virus (VMV and the Caprine Arthritis-Encephalitis Virus (CAEV, which infect sheep and goats. Both infect cells of the monocyte/macrophage lineage and cause lifelong infections. Infection by VMV and CAEV can lead to Visna/Maedi (VM and Caprine Arthritis-Encephalitis (CAE respectively, slow progressive inflammatory diseases primarily affecting the lungs, nervous system, joints and mammary glands. VM and CAE are distributed worldwide and develop over a period of months or years, always leading to the death of the host, with the consequent economic and welfare implications. Currently, the control of VM and CAE relies on the control of transmission and culling of infected animals. However, there is evidence that host genetics play an important role in determining Susceptibility/Resistance to SRLV infection and disease progression, but little work has been performed in small ruminants. More research is necessary to understand the host-SRLV interaction.

    Full Text Available Utilization of the Mediterranean shrubby vegetation is often limited by secondary compounds, such as terpenes, which at too high concentrations can adversely affect forage intake and animal health. Ingesting compounds such as activated charcoal and energy can ameliorate the negative effects of secondary compounds and enable animals to eat more shrubs. Thus, our objectives were to determine if supplemental charcoal, energy and numbers of shrub species offered influenced intake of shrubs by sheep and goats. We conducted three experiments each with 12 lambs and 12 kids (6 activated charcoal vs. 6 controls. In the first experiment, we initially offered three shrubs (Juniperus phoenicea, Helichrysum italicum and Juniperus oxicedrus, then in the second one, two shrubs (Juniperus phoenicea and Helichrysum italicum, and finally one shrub (Juniperus phoenicea in the third experiment. In all three experiments (Exp. 1, P<0.001; Exp. 2, P < 0.0003 and Exp. 3, P < 0.03, supplemental charcoal and energy had a positive effect on total shrub intake for both lambs and kids. Kids ate more shrubs than lambs did in all three experiments (P<0.01. Regardless of experiment, both species of animals showed a numerical decrease in total shrub intake, with or without supplemental charcoal and energy, as the number of shrub species on offer decreased. Our findings support the hypothesis that biochemical diversity plays an important role in diet selection, thus enabling animals to better meet their nutritional needs and avoid toxicity.

    Sheep manure pellets are peculiarly shaped as small 'capsules' of limited permeability and thus are difficult to degrade. Fragmentation of manure pellets into a homogeneous mass is important for decomposition by microorganisms, and occurs naturally by physical shearing due to animal trampling, when sheep bedding is used. However, the high lignocellulose content of sheep bedding may limit decomposition of sheep manure. Here, we evaluated if co-digestion of sheep bedding with cattle manure would improve the yield and quality of the useful products of anaerobic digestion of sheep bedding--biogas and biofertilizer--by providing a source of nutrients and readily available carbon. Mixtures of sheep bedding and cattle manure in varying proportions (0%, 25%, 50%, 75%, or 100% cattle manure) were added to 6-L digesters, used in a batch system, and analyzed by uni and multivariate statistical tools. PC1, which explained 64.96% of data variability, can be referred to as 'organic fraction/productivity', because higher rates of organic fraction consumption (COD, cellulose and hemicellulose contents) led to higher digester productivity (biogas production, nutrient concentration, and sample stability changes). Therefore, productivity and organic fraction variables were most influenced by manure mixtures with higher (⩾ 50%) or lower (⩽ 25%) ratios of cattle manure, respectively. Increasing the amount of cattle manure up to 50% enhanced the biogas potential production from 142 L kg(-1)TS (0% of cattle manure) to 165, 171, 160 L biogas kg(-1)TS for the mixtures containing 100%, 75% and 50% of cattle manure, respectively. Our results show that the addition of ⩾ 50% cattle manure to the mixture increases biogas production and improves the quality of the final biofertilizer. PMID:26341827

    Objective: To determine the fauna and frequency of hard tick species on sheep and cattle in Hamedan Province, Western Iran. Methods: Tick sampling was performed on the whole body of 18000 sheep and 4200 cattle in 3 rural regions (mountain, plateau, and plain-mountainous zone) during the year of 2010 to 2011. The ticks were identified with appropriate identification keys. Results: A total of 1534 hard ticks (62.1% male and 37.9% female) were collected in animals. The infestation rate was found 2.4% in animals (4.2% in cattle and 2.0% in sheep). The ticks were classified into 3 genera and 7 species including: Hyalomma marginatum (34.1%), Hyalomma excavatum (29.7%), Rhipicephalus bursa (13.8%), Rhipicephalus sanguineus (7.5%), Hyalomma detritum (7.1%), Haemaphysalis punctata (5.1%) and Hyalomma dromedarii (2.7%). Conclusions: Current study is the first report of fauna and frequency of hard ticks in this region. The results showed that Hyalomma marginatum is the dominant hard tick species. Further studies are needed to determine the importance of Ixodidae ticks of veterinary and public health in this region of Iran.

    Full Text Available Sheep and goat farming is considered to be one of the most dynamic sectors of the rural economy in Greece, both in terms of employment and overall income. The aim of this paper is to review the levels of sustainability in the small ruminant production systems in two Less Favoured Areas of Greece (LFAs: (1 in the mountainous areas of Epirus, and (2 in the island of Lesvos. In this context, the characteristics of the production systems that have significant impact on the sustainable development of rural areas under study are underlined. The sustainability is examined by the ecological, social and economic points of view, supplemented with cultural and regional elements. The ultimate purpose is to conclude with the challenges for the future rural development in LFAs through the sustainable development of sheep and goat farming. Data is based on surveys undertaken by the SEE-ERA.NET PLUS ‘INDI_SHEEP TRADI_CHEESE’ Project and the ARIMNET ‘DoMEsTIc’ Project, still in process.

    The Chinese Brucella suis S2 vaccine was studied in a flock of sheep and goats in field conditions. The locally-produced vaccine was orally administered in the form of a drench to 446 ewes, 50 lambs and 20 adult goats. After vaccination, abortion and excretion of the vaccine strain in vaginal discharges or in milk did not occur. Serological tests became positive in 92% of animals at 4 wk post-vaccination and declined to near nil after 1 yr. The protection conferred by the vaccine against a double virulent B melitensis conjunctival challenge which infected 10/10 control ewes was on average 53% in ewes (32/60) and 71% in goats (5/7). Abortion rates were respectively 100% (7/7) in control ewes versus 44% (25/57) and 28% (2/7) in vaccinated ewes and goats. The vaccine was thus found to be safe, antigenic and reasonably protective against the challenge dose used. PMID:8260964

  20. Technical specifications on harmonised epidemiological indicators for biological hazards to be covered by meat inspection of domestic sheep and goats

    European Food Safety Authority

    2013-06-01

    Full Text Available In this report, harmonised epidemiological indicators are proposed for food-borne biological hazards that are related to domestic sheep and goats and meat thereof and that can be addressed in the context of meat inspection. These hazards include Toxoplasma gondii, pathogenicverocytotoxin-producing Escherichia coli and mycobacteria. An epidemiological indicator is defined as the prevalence or concentration of the hazard at a certain stage of the food chain or an indirect measure of the hazard that correlates with the human health risk caused by the hazard. The indicators can be used by the European Commission and the Member States to consider when adaptations to meat inspection methods may be required, and to carry out risk analysis to support such decisions. It is foreseen that the indicators will be used in the integrated sheep and goats meat safety assurance system outlined in the EFSA Scientific Opinion on the public health hazards to be covered by inspection of meat from sheep and goats, particularly to help categorise farms/flock and slaughterhouses according to the risk related to the hazards and process hygiene. Depending on the purpose and the epidemiological situation, risk managers should decide on the most appropriate indicator(s to use, either alone or in combination, at national, regional, slaughterhouse or farm/flock level. It is recommended that risk managers should define the harmonised requirements for controlled housing conditions of farms, and the requirements for food chain information. Member States are invited to report data generated by the implementation of the indicators in accordance with Directive 2003/99/EC. The proposed indicators should be regularly reviewed in light of new information and the data generated by their implementation.

  1. A Seroepidemiological Survey of Crimean Congo Hemorrhagic Fever among Goats and Sheep in Lezhe Torovica Province, Albania

    Full Text Available Crimean-Congo hemorrhagic fever (CCHF is a zoonotic vector-born viral disease with a case fatality rate of 2-50% in human. CCHFV is classified within the Nairovirus genus in the Bunyaviridae family. The virus is endemic in over 30 countries, including Albanian. Animals can infect by virus without clinical symptoms.. The virus can be transmitted mainly through direct contact with blood or tissues from infected livestock or through bites of Hyalomma ticks. The aim of this study was to examine the distribution of CCHFV among sheep and goats in Lezha-Torovica region of Albania. This survey was carried out in 2013. In all, 50 blood samples were taken from the jugular veins of the sheep, and 50 blood samples were taken from the jugular veins of the goats. The samples were immediately taken to the laboratory and their serum extracted, separated by a centrifuge with 3500 rpm in 10 minutes. They were kept in the Faculty of Veterinary Medicine, Agricultural University of Tirana, at a temperature below 20°C until analysis and tested with immunological methods using indirect ELISA assay in Friedrich-Loeffler Institute (FLI, Greifswald Germany. Through this technique it was possible to identified IgG antibodies in infected serum samples. The prevalence of this infection in animals is obviously different, in goats is higher than in sheep, respectively 90% and 24%. It is recommended that further studies be carried out on additional livestock, high-risk groups of humans, and ticks, to determine the CCHF disease status in Lezha-Torovica.

    Biosecurity is important in order to prevent disease transmission between animals on farms as well as from farm to farm. Personal biosecurity routines such as hand washing and the use of protective clothing and footwear are measures that should be used at all farms. Other measures are for example related to purchasing new animals to the farm. A questionnaire-based survey was undertaken to study the frequency of use of different biosecurity measures on cattle, pig and sheep farms in Finland. Information about which biosecurity measures are in use is needed for contingency planning of emerging diseases or when combating endemic diseases. Knowledge about the level of biosecurity of a farm is also needed in order to assess if and where improvement is needed. Information regarding biosecurity levels may benefit future animal disease risk assessments. A total of 2242 farmers responded to the questionnaire resulting in a response rate of 45%. The implementation frequencies of different biosecurity measures are reported. The results revealed differences between species: large pig farms had a better biosecurity level than small cattle farms. There were also differences between production types such as dairy farming versus beef cattle farming, but these were not as remarkable. Sheep farming in Finland is sparse and the large number of hobby farmers keeps the biosecurity level low on sheep farms. This might represent a risk for the entire sheep farming industry. The Finnish farmers were satisfied with their on-farm biosecurity. Eighty percent of the farmers report that they were satisfied even though the biosecurity level was not particularly high. The implementation of biosecurity measures could be further improved. Even though the disease situation in Finland is good today, one must be prepared for possible epidemics of threatening diseases.

    Full Text Available At the present time, the meat of goat is the fastest growing class of livestock in the U.S.A. Due to the sub-tropical climate in the South Eastern region of the US, internal parasites pose a major constraint to the industry. The blood-feeding nematode, Haemonchus contortus results in production losses and even death in untreated animals. The control of H. contortus calls for the use of a combination of different control methods/strategies. An experiment was conducted over three successive years (2008, 2009 and 2010 to evaluate the effects of mixed species grazing on fecal egg counts (FEC in epg, FAMACHA© scores (FS and Packed Cell Volume (% PCV in goats. In a 2×2 factorial, 50 Spanish does and 14 Brangus cows were randomly assigned to continuous or rotational grazing systems. Goats were allowed to graze alone or mixed with cattle. The rotational pastures were divided into four paddocks and each paddock was grazed for 7d and allowed to rest for 21d. Every 28d Body Weight (BW, body condition scores (BCS; 1 = thin and 5 = fat, FS (1 = red and 5 = white, blood and feces were collected. Fecal and blood samples were analyzed in the lab for FEC and %PCV. Data was statistically analyzed using SAS’s MIXED and correlation coefficients were determined among the measurements. Overall means for PCV, FEC, BCS and FS were 27.4%, 613 epg, 2.3 and 2.5, respectively. PCV was negatively correlated to FS (r = -0.35, p<0.001 and FEC (r = -0.16, p<0.005. BCS was negatively correlated to FS (r = -0.59, p<0.001 and FEC (r = -0.17, p<0.005, while FS and FEC were positive (r = 0.20, p<0.005. Except for the effect of month (p<0.05, no differences due to the main effects were observed and interaction effects were significant at only p<0.10. Goats grazing alone in continuous pastures had a higher PCV and FS scores (28.6% and 2.7, respectively than goats in mixed rotational pastures (25% and 2.2. The percentages of does in mixed pastures falling in FS-1, FS-2 and

    Villalba, J J; Provenza, F D; Banner, R E

    2002-12-01

    We determined if supplemental macronutrients or polyethylene glycol (PEG) influenced intake of a tannin diet. Sheep (lambs 5 mo age, 36 kg) and goats (kids 7 mo age, 32 kg) were fed supplements high in either energy or protein or offered a choice between the two supplements before and after receiving a meal containing 15% quebracho tannin. The effect of PEG, a compound that attenuates the negative effects of tannins, was assessed by offering PEG while animals consumed the tannin diet for 4 h/d. Intake of the tannin diet was influenced by both macronutrients and PEG. Animals that chose their own supplements or that received the high-protein supplement, consumed more of the tannin diet than animals fed the high-energy supplement: 34 and 36 vs 31 g/kg(0.75) (lambs) and 41 and 39 vs 34 g/kg(0.75) (kids), respectively (P < 0.05). Animals supplemented with PEG ate much more of the tannin diet than unsupplemented animals: 70 vs 39 g/kg(0.75) (lambs) and 63 vs 34 g/kg(0.75) (kids), respectively (P < 0.001). Sheep and goats consumed more tannin food when given PEG than when supplemented with macronutrients (51 and 38 g/kg(0.75), P < 0.001). Sheep and goats offered a choice between supplements consumed more CP than animals fed the high-energy supplement and more ME than animals fed the high-protein supplement (P < 0.05). In so doing, they selected a combination of foods that yielded a more balanced intake of macronutrients, while achieving high levels of intake of the tannin food. Sheep and goats can be used as an environmentally safe and economically sound means to reduce the abundance of tannin-rich vegetation. Macronutrients and PEG enhance use of tannin-containing plants, which may increase production of alternate forages and create a more diverse mix of species in a plant community. PMID:12542156

    EFSA Panel on Animal Health and Welfare (AHAW

    2013-12-01

    Full Text Available This scientific opinion proposes toolboxes of welfare indicators for developing monitoring procedures at slaughterhouses for sheep and goats stunned with the head-only electrical method or slaughtered without stunning. In particular, the opinion proposes welfare indicators together with their corresponding outcomes of consciousness, unconsciousness or death. In the case of slaughter with head-only electrical stunning, the opinion proposes a toolbox to assess consciousness at three key stages of monitoring: (a after electrical stunning and during shackling and hoisting, (b during neck cutting and (c during bleeding. For slaughter without stunning, another toolbox is proposed for (a assessing unconsciousness before releasing the animals from restraint, and (b confirming death before carcass dressing begins. Various activities—including a systematic literature review, an online survey and stakeholders’ and hearing experts’ meetings—were conducted to gather information about the sensitivity, specificity and feasibility of the indicators. On the basis of such information, a methodology was developed to select the most appropriate indicators to be used in the monitoring procedures. The frequency of checking differs according to the role of each person with responsibility for ensuring animal welfare. The personnel performing stunning, shackling, hoisting and/or bleeding will have to check all the animals and confirm that they are not conscious following stunning or before releasing from the restraint. For the animal welfare officer, who has the overall responsibility for animal welfare, a mathematical model for the sampling protocols is proposed, giving some allowance to set the sample size of animals to be checked at a given throughput rate (total number of animals slaughtered in the slaughterhouses and threshold failure rate (number of potential failures—proportion of animals that are conscious after stunning.

    Full Text Available Abstract Background Given the theoretical proposal that bovine spongiform encephalopathy (BSE could have originated from sheep scrapie, this study investigated the pathogenicity for cattle, by intracerebral (i.c. inoculation, of two pools of scrapie agents sourced in Great Britain before and during the BSE epidemic. Two groups of ten cattle were each inoculated with pools of brain material from sheep scrapie cases collected prior to 1975 and after 1990. Control groups comprised five cattle inoculated with sheep brain free from scrapie, five cattle inoculated with saline, and for comparison with BSE, naturally infected cattle and cattle i.c. inoculated with BSE brainstem homogenate from a parallel study. Phenotypic characterisation of the disease forms transmitted to cattle was conducted by morphological, immunohistochemical, biochemical and biological methods. Results Disease occurred in 16 cattle, nine inoculated with the pre-1975 inoculum and seven inoculated with the post-1990 inoculum, with four cattle still alive at 83 months post challenge (as at June 2006. The different inocula produced predominantly two different disease phenotypes as determined by histopathological, immunohistochemical and Western immunoblotting methods and biological characterisation on transmission to mice, neither of which was identical to BSE. Whilst the disease presentation was uniform in all scrapie-affected cattle of the pre-1975 group, the post-1990 inoculum produced a more variable disease, with two animals sharing immunohistochemical and molecular profile characteristics with animals in the pre-1975 group. Conclusion The study has demonstrated that cattle inoculated with different pooled scrapie sources can develop different prion disease phenotypes, which were not consistent with the phenotype of BSE of cattle and whose isolates did not have the strain typing characteristics of the BSE agent on transmission to mice.

    After exposure for two hours to cattle with foot-and-mouth disease, each of the five species of deer found in the British countryside became infected. Clinical disease was typical and severe in the roe and muntjac deer, with some animals dying, less severe in the sika deer and usually subclinical in the fallow and red deer. Each species transmitted disease to its own species and to cattle and sheep. The amounts of virus present in the blood, and in oesophageal/pharyngeal samples and excreted as an aerosol during the course of the infection in the deer were similar to those recorded for the sheep and cattle in the same experiment. The fallow and sika deer commonly carried virus in the pharynx beyond 28 days after exposure; some red deer also became carriers. In epidemics of foot-and-mouth disease in the UK, it is likely that deer would have such intimate contact with farm animals as occurred in this study. The natural behavior of free-living deer in the UK suggests that, although the five species are susceptible to foot-and-mouth disease, they are unlikely to be an important factor in the maintenance and transmission of the virus during an epidemic of foot-and-mouth disease in domestic livestock.

  13. Application of C-ELISA for the sero-survey of rinderpest virus antibody in cattle and goats in Bangladesh

    International Nuclear Information System (INIS)

    The aim is to study the applicability of C-ELISA for seromonitoring of antibodies against RP virus in ruminants in Bangladesh. As no outbreaks of RP have been reported since 1957, a broader belt rinderpest vaccination programme is being carried out in order to protect cattle from rinderpest originating from neighbouring States of India. However, the emergence of rinderpest-like epidemics in goats has been noticed for the last three years. Thus, the use of the rinderpest competitive ELISA technique will be helpful to measure the current status of rinderpest serosurveillance as well as to confirm the rinderpest-like epidemics in goats as peste des petits ruminants (PPR) in Bangladesh

  14. Comparative efficacy of allopathic, herbal, homeopathic and effective micro-organisms for the control of haemochosis in sheep and goats

    International Nuclear Information System (INIS)

    Haemonchosis caused by Haemonchus contortus causes great economic losses in terms of weight loss, poor quality meat and loss of wool in sheep and goats. Therapeutical trials were conducted by using various allopathic, homeopathic, herbal and biological products. For this purpose total of 120 sheep and goats were randomly divided into groups A, B, C, D, E and F and animals in group A, B, C and D were treated with Ivermectin, Azedarachta indica (neem Leaves) Powder, Trematox (a homeopathic drug), EM-Biovet (Effective micro-organisms) respectively. Whereas E and F were kept as infected untreated and control respectively. Efficacy of drugs was measured based on reduction in EPG count, it was found that ivermectin at recommended dose rate is found more effective; Azedarachta Indica (Neem) found second and Trematox third drug of choice in combating the infection against haemonchosis, whereas EM Biovet was inferior to other drugs. In these studies it was found that Azedarachta Indica (Neem) is cheapest and easily available drug than others. Comparison based on reduction in EPG count indicated that Azedarachta indica and Trematox were fairly affective in combating haemonchosis but EM Bio-vet fail to cure all cases of haemonchosis. It was also noted that all drugs were more affective at two-dose level as compared to one dose level. Ivermectin proved to be best drug against haemonchosis. Efficacy of Azedarachta indica (neem) found to be closer to Ivermectin and EM Bio-vet was inferior as compared to Ivermectin. (author)

    2006-06-01

    The present work investigates some clinical, endocrinological, biochemical and haematological variables in desert sheep and goats stressed in the course of individual road transportation, and the influence thereon of pretreatment with an established anti-stressor drug, xylazine HCl, and a test compound, sodium betaine (trimethylglycine). Road transportation for 2h resulted in variable and statistically insignificant increases in heart, pulse and respiratory rates in both control and experimental animals. Transportation stress significantly increased the concentrations of plasma cortisol, and glucose, and decreased that of magnesium. The endogenous thiocyanate concentration was unaffected. The stress also insignificantly decreased the haematocrit (PCV), and the number of lymphocytes, and increased the concentration of haemoglobin. Pretreatment of sheep and goats with xylazine at a single dose of 0.01 mg/kg by the intravenous route significantly ameliorated the effects induced by the stressful stimulus. The effects of pretreatment of the two species with sodium betaine (10 mg/kg) produced variable and insignificant effects. PMID:16181650

The objectives of the experiments were (1 to determine the toxicity to goats of fresh I. asarifolia collected during the raining and the dry season, and the toxicity of the dried plant, and (2 to determine the toxicity of the plant to sheep, and if the active principle is eliminated through the milk. In the first experiment the plant collected in the dry season and in the raining season was fed to 16 goats. The plant collected during the dry season caused clinical signs at the daily doses of 5g and 10g/kg body weight. The plant collected during the raining season was toxic at daily doses of 20g and 30g/kg, indicating that the plant is more toxic during the dry season. The plant collected in the dry season and dried was fed to 9 goats at doses of 1.7g, 2.0g, 3.4g, and 5.1g per kg. Daily doses of 3.0g, 4.0g and 5.1g/kg caused clinical signs, showing that the plant maintains its toxicity after being dried. In the second experiment the fresh plant collected in the dry and in the raining season was fed to 10 sheep. The plant collected in the dry season was toxic at the dose of 5g/kg, and the plant collected in the raining season was toxic at the doses of 10g and 20g/kg.

    The spinosyns are a novel family of fermentation-derived natural products that exhibit potent insecticidal activities. Spinosad, a naturally-occurring mixture of spinosyn A and spinosyn D, has successfully established its utility for crop protective applications in the agrochemical field. Potential applications of this unique chemical family of macrolides also have been investigated in the field of animal health. Applications for the control of blowfly strike and lice on sheep have now been commercially developed and registered in Australia and potential applications for the control of ectoparasites on cattle are being studied.

    A total of 42 lambs, 42 kids, 21 ewes and 21 does were necropsied during an investigation of the epidemiology of Haemonchus contortus infection of sheep (Red Maasai) and goats (Small East African Goat) in a semi-arid area of Kenya. Availability and establishment of the infective stages were monitored by the necropsy of 21 tracer lambs and 21 tracer kids. Prevalence of H. contortus was over 90% in both sheep and goats and this species contributed to about 80% of the total worm burden. Only about 10% of the hypobiotic larvae were recovered from the mucosal digest whereas about 90% were recovered from the abomasal contents and washings, thereby suggesting that hypobiotic larvae may be loosely attached to the abomasal mucosa from which they may be dislodged during the processing of the abomasa for examination. Throughout the study, both adult worms and hypobiotic larvae were found in proportions that varied with seasons. Statistically, a higher proportion of hypobiotic larvae was found during the dry months than during the wet months, an indication that hypobiosis was an important feature in the survival of H. contortus during the dry months. Negligible worm burdens were acquired by the tracers during the short rains, suggesting that few H. contortus larvae survived on pasture in this season. The effectiveness of strategic control using ivermectin varied according to the timing in relation to the wet season. Treatment did not influence the seasonal pattern of hypobiosis but the treatment administered before the onset of the rains significantly reduced the numbers of both hypobiotic larvae and the adult worms. Treatment during the rains conferred a temporary relief of adult worm burden but had no impact on hypobiotic larvae. PMID:9652383

    Objective: To examine the oocytes maturation capacity of buffalo, sheep and goat using media containing sera of three different groups of buffaloes (regularly cycling, pregnant and repeat breeding). Methods: The buffalo, sheep and goat oocytes were matured under suitable conditions in medium containing sera of regularly cycling, pregnant and repeat breeding buffaloes. Results:The oocytes maturation rate containing buffalo oocytes cultured in media containing sera of the control group and regularly cycling group were not significantly different. However when oocytes cultured in the media containing sera of pregnant buffaloes the maturation rate were significantly declined. Further significant declined in maturation rate were observed when oocytes cultured in media containing sera of repeat breeding buffaloes. When sheep and goat oocytes cultured in the media containing control, pregnant and regularly cycling animals sera the oocytes maturation rate were not significantly different. A significant decline in maturation rate of sheep and goat oocytes were observed, when oocytes cultured in media containing sera of repeat breeding buffaloes. Conclusion: We may conclude that serum collected from normal cycling buffaloes can be used for oocytes maturation in both homogeneous and heterogeneous species.

    Full Text Available This study investigated the withdrawal periods (WP of two intramammary antibiotics Cloxamast LC (Intervet SA and Spectrazol Milking Cow (Schering-Plough Animal Health in dairy goats and compared them to those recommended for use in cattle. The WP for Cloxamast LC, measured by the Thermo Resistant Inhibitory Substances (TRIS test, was 60 h in composite samples, 56 h in udder half samples, and the dye was visible for up to 56 h. The WP was significantly shorter than the 72 h recommended WP for use in cattle. It was however significantly longer when the 24 h safety margin (48 h was subtracted from the recommended WP for cattle. For Spectrazol Milking Cow the antibiotics could be detected by the TRIS test for 61 h in composite samples and 59 h in udder half samples. This did not differ significantly from the recommended 60 h WP for cattle. However, it was significantly longer than that recommended for use in cattle without the 24 h safety margin. There was no significant difference in WP between infected and non-infected udder halves, while there was a weak positive correlation between WP and stage of lactation (R2 = 0.253. There was a moderate positive correlation (R2 = 0.583 between the TRIS test and the presence of dye in milk in udder half samples and between WP in both udder half and composite milk samples (R2 = 0.456. Weak to moderate positive correlations were present between milk yield and the WP in both udder half (R2 = 0.414 and composite (R2 = 0.262 milk samples. Significant differences (P < 0.001 were also observed between the milk yield of udder halves with and without palpable udder damage and between samples that tested TRIS positive and negative on both composite (P = 0.008 and udder half samples (P < 0.001. There was no significant difference between the milk yield of samples with or without dye. There was a significant difference in milk yield between infected and non-infected udder halves (P = 0.054 and a weak negative correlation

  4. Absorption, tissue distribution, and excretion of tritium-labeled ivermectin in cattle, sheep, and rat

    International Nuclear Information System (INIS)

    Tritium-labeled ivermectin was studied in cattle, sheep, and rat for absorption, tissue residue distribution, and excretion at doses of 0.3 mg/kg of body weight. The drug was absorbed by various dosing routes. By intraruminal and subcutaneous dosing routes, highest tissue residues were present in fat and liver of cattle, with half-lives of 6-8 and 4-5 days, respectively. Shorter half-lives (1-2 days) were observed in sheep and rat. The tissue residue distribution pattern was essentially the same for all species studied and similar in male and female rats. With doses of tritium-labeled avermectin B1a ranging from 0.06 to 7.5 mg/kg of body weight, plasma and tissue residue concentrations increased proportionally with the dose. When ivermectin was administered by various routes (ip, sc, iv, oral, and intraruminal), blood residue levels converged to 20-50 ppb 4 h after dosing and then depleted at similar rate regardless of the dosing route. Ivermectin was excreted primarily in the feces, with only less than 2% of the doses being eliminated in the urine in all three species studied

    The main objective of the study was to determine the possible influence of host species on the maintenance of ticks in the field by determining the relative contribution of game animals compared to domestic animals. The study was carried out on a game ranch 32 km south-east of Nairobi. Tick counts were carried out on 30 Zebu cattle (Bos indicus) aged 1 to 3 years and 20 red Maasai sheep (Ovis aries) aged 6 months to 1 year grazing with game animals in a common area for a period of 2 years and these counts were compared with those on eland and Thomson's gazelle. Half-body counts were carried out on the cattle and sheep once every week. To avoid excessive stress, the animals were dipped in amitraz whenever the half body counts exceeded 50 fully engorged female ticks of any species. Tick counts on two wild animal species (eland (Taurotragus oryx) and Thomson's gazelle (Gazella thomsonii)) were carried out during the weekly culling of the herbivores. The results revealed that there was no significant difference in the number ticks per square metre between the wild ungulates and the domestic animals. PMID:17405627

    Full Text Available Understanding genetic structure and status of genetic variation of Fasciola hepatica isolates from different hosts, has important implications on epidemiology and effective control of fasciolosis. Random amplified polymorphic DNA (RAPD-PCR was used to study the genetic variation of F. hepatica in sheep and cattle. DNA was extracted from adult helminthes removed from livers of each infected animal in slaughterhouse at East-Azerbaijan province, North-West of Iran. DNA template amplified by the polymerase chain reaction, using three oligonucleotide decamers with arbitrary DNA sequences as primers. RAPD patterns showed the specific but different pattern DNA patterns for each primer. The intraspecific similarity coefficient within two isolates of F. hepatica was ranged between 69 to 100%. Present findings showed that the interspecific genetic distance was higher than intraspecific genetic distances (19-47% compares to 0-19%. Pair wise similarity matrices generated from each isolates-primer combination were totaled and the similarity coefficient between strains were calculated both manually (Nei and Li method and software analysis (Free-Tree-Freeware program. The inferred phylogenetic tree on the fingerprinting of these isolates clearly demonstrated the existence of population genetic diversity sub structuring within F. hepatica of sheep and cattle of Iran, raising interesting questions on the host specificity, epidemiology (e.g., zoonotic transmission and ecology of this fluke. RAPD-PCR is useful for both individual identification and epidemiological investigations in endemic regions.

    Cattle, sheep and rats were infected orally with ..gamma..-irradiated metacercariae of Fasciola hepatica, or with normal metacercariae. The antibody response was monitored in each host to metacercarial tegument (T0), juvenile tegument (T1), adult tegument (T2) and gut antigens. The response was examined at weekly intervals for cattle and sheep throughout 15 weeks of infection and four weeks after infection in rats, using an indirect fluorescent antibody labelling technique. It was found that the irradiated metacercariae engendered a normal humoral response to T0, T1 and gut antigens in all three hosts although the antibody levels were somewhat reduced due to early death or stunting of the flukes. T0 and T1 appeared to be antigenically similar. Antibodies against T2 appeared late in the animals infected with ..gamma..-irradiated metacercariae and the titres attained were considerably lower than in the controls. The T2 antigen stimulus in the animals given ..gamma..-irradiated metacercariae was probably provided by flukes which 'broke through' the developmental barrier imposed by irradiation and which were found alive at autopsy.

    Full Text Available Abstract Background Comparatively little is known about the prevalence or the molecular characteristics of the zoonotic pathogen E. coli O157:H7 in the sheep reservoir. To investigate this and determine the host specificity of subclones of the bacterium, we have conducted a slaughterhouse prevalence study in sheep and compared the collected isolates to O157:H7 previously isolated from cattle and human patients. Results Verotoxin-producing O157:H7 was found in 11/597 (1.8% of samples from sheep in Swedish slaughterhouses, 9/492 faecal (1.8% and 2/105 ear samples (1.9%. All positive sheep were eaeA, hlyA, cdtV-B, vtx1, and partial sequencing of vtx2. The observed profiles were similar to those of cattle strains investigated previously. Conclusions The same pathogenic subtypes of VTEC O157:H7, including the highly virulent clade 8, appear to be present in both sheep and cattle in Sweden, suggesting strains can circulate freely between ruminant reservoirs.

    The aim of the present study was to detect Toxoplasma gondii DNA in raw milk samples of goats and sheep of local breeds from the semi-arid region of the states of Pernambuco and Paraíba, Northeastern Brazil. Serum and milk samples were collected from 243 animals (186 goats and 57 sheep). The Indirect fluorescent antibody test (IFAT) was used to search for anti-T. gondii IgG antibodies with a cutoff of 64. Subsequently, the raw milk samples were subjected to DNA extraction and PCR to detect DNA of T. gondii. The IFAT results showed a 6.58% (16/243) positivity when all the samples were considered and a positivity of 15.78% (9/57) and 3.76% (7/186) for goats and sheep samples, respectively. The PCR assay detected T. gondii DNA in 2.06% (5/243) of all the samples tested. All the PCR positive samples were from goats. This result shows the importance of adopting measures of flock's sanitary management and avoiding the consumption of raw milk may constitute a potential risk to the health of milk consumers in this region.

    Ricotta cheese is a typical Italian product, made with whey from various species, including cow, buffalo, sheep, and goat. Ricotta cheese nominally manufactured from the last three species may be fraudulently produced using the comparatively cheaper cow whey. Exposing such food frauds requires a reliable analytical method. Despite the extensive similarities shared by whey proteins of the four species, a mass spectrometry-based analytical method was developed that exploits three species-specific peptides derived from β-lactoglobulin and α-lactalbumin. This method can detect as little as 0.5% bovine whey in ricotta cheese from the other three species. Furthermore, a tight correlation was found (R(2)>0.99) between cow whey percentages and mass spectrometry measurements throughout the 1-50% range. Thus, this method can be used for forensic detection of ricotta cheese adulteration and, if properly validated, to provide quantitative evaluations. PMID:26675863

  13. Scientific Opinion on the public health hazards to be covered by inspection of meat from sheep and goats

    Directory of Open Access Journals (Sweden)

    EFSA Panel on Biological Hazards (BIOHAZ

    2013-06-01

    Full Text Available A risk ranking process identified Toxoplasma gondii and pathogenic verocytotoxin-producing Escherichia coli (VTEC as the most relevant biological hazards for meat inspection of sheep and goats. As these are not detected by traditional meat inspection, a meat safety assurance system using risk-based interventions was proposed. Further studies are required on T. gondii and pathogenic VTEC. If new information confirms these hazards as a high risk to public health from meat from sheep or goats, setting targets at carcass level should be considered. Other elements of the system are risk-categorisation of flocks/herds based on improved Food Chain Information (FCI, classification of abattoirs according to their capability to reduce faecal contamination, and use of improved process hygiene criteria. It is proposed to omit palpation and incision from post-mortem inspection in animals subjected to routine slaughter. For chemical hazards, dioxins and dioxin-like polychlorinated biphenyls were ranked as being of high potential concern. Monitoring programmes for chemical hazards should be more flexible and based on the risk of occurrence, taking into account FCI, which should be expanded to reflect the extensive production systems used, and the ranking of chemical substances, which should be regularly updated and include new hazards. Control programmes across the food chain, national residue control plans, feed control and monitoring of environmental contaminants should be better integrated. Meat inspection is a valuable tool for surveillance and monitoring of animal health and welfare conditions. Omission of palpation and incision would reduce detection effectiveness for tuberculosis and fasciolosis at animal level. Surveillance of tuberculosis at the slaughterhouse in small ruminants should be improved and encouraged, as this is in practice the only surveillance system available. Extended use of FCI could compensate for some, but not all, the information

    The generally warm, moist environmental conditions in the southern United States (U.S.) are ideal for survival and growth of the egg and larval stages of Haemonchus contortus and other gastrointestinal nematodes (GIN) of sheep and goats. Consequently, infection with GIN is the greatest threat to economic small ruminant production in this region. With anthelmintic resistance now reaching epidemic proportions in small ruminants in the U.S., non-chemical control alternatives are critically needed. The Southern Consortium for Small Ruminant Parasite Control (SCSRPC) was formed in response to this crisis and over the last decade has successfully validated the use of several novel control technologies, including FAMACHA(©) for the implementation of targeted selective treatments (TST), copper oxide wire particles (COWP), nematode-trapping fungi, and grazing or feeding hay of the high-tannin perennial legume sericea lespedeza [Lespedeza cuneata (Dum.-Cours. G. Don)]. Producer attitudes toward GIN control in the U.S. have been shifting away from exclusive dependence upon anthelmintics toward more sustainable, integrated systems of parasite control. Some novel control technologies have been readily adopted by producers in combination with appropriate diagnostic tools, such as FAMACHA(©). Others techniques are still being developed, and will be available for producer use as they are validated. Although new drugs will likely be available to U.S. goat and sheep producers in the future, these will also be subject to development of anthelmintic resistance. Therefore, the adoption and implementation of sustainable GIN control principles will remain important. With emerging markets for grass-fed or organic livestock, there will continue to be a critical need for research and outreach on development and on-farm application of integrated GIN control systems for small ruminants in the U.S. for the foreseeable future.

    Resistance against the major currently available anthelmintics has reached a critical level in many small ruminant herds world-wide, and is increasingly becoming a problem in horses and cattle. Therefore, new products with different modes of action are urgently needed. Recently, such a new class of compounds, the anthelmintically active cyclooctadepsipeptides, was described. Here, the effects of cyclooctadepsipeptides on benzimidazole-, levamisole- and ivermectin-resistant populations of Haemonchus contortus in sheep as well as an ivermectin-resistant Cooperia oncophora population in cattle were studied. Experimentally infected sheep and cattle were used. Animals were treated orally, subcutaneously, or intravenously with cyclooctadepsipeptides. The anthelmintic effects were assessed by means of fecal egg count reductions and/or worm count reductions. Both, PF1022A and emodepside were found to be fully effective against these parasite populations. These findings confirm that this new class of compounds acts by a different mode of action compared to the above-mentioned anthelmintics. PMID:15796017

    The effect of three pork backfat levels (0% vs. 10% vs. 30%) on chemical composition, fatty acid profile and sensory properties on sheep and goat meat sausages was studied. All physicochemical parameters were affected by the addition of pork backfat in both types of sausages. Sausages manufactured with 30% of pork backfat showed the lowest moisture and protein contents and the highest total fat content. The lower a(w) values in sausages manufactured with higher fat content while in pH happened the reverse situation. The addition of pork backfat modified the total fatty acid profile, prompting a significant drop in the relative percentages of C14:0, C16:0, C17:0, C17:1, C18:0 and TVA (trans-vaccenic acid), together with a marked increase in oleic and linoleic acids. Finally, in goat sausages, the fat content significantly affected sensory parameters: taste, texture and overall acceptability (P<0.05). As expected, all physicochemical parameters were affected by the addition of pork backfat in both types of sausages. PMID:25839884

    Full Text Available Abstract Background Domestic goats (Capra hircus are a natural and experimental host of scrapie and bovine spongiform encephalopathy, the transmissible spongiform encephalopathies (TSE of sheep and cattle. Goats are also susceptible to experimental infection with the agents of TSEs of deer and elk (chronic wasting disease and humans (Creutzfeldt Jakob disease. Distribution of PrPSc, the abnormal prion protein, is similar in the tissues of scrapie-infected sheep and goats but no data are available on the potential shedding of the agent through the placenta, the presumed route of transmission of ovine scrapie. We describe the sparse accumulation of PrPSc in the placentas of goats with naturally acquired classical scrapie in comparison to field cases of classical ovine scrapie. Results PrPSc was detected in the shed placentas from a sample of U.S. goats with naturally occurring scrapie, diagnosed by antemortem lymphoid tissue biopsy or identified as high risk progeny of infected dams. PrPSc accumulation patterns in the intact placentome and western blot banding was similar in the caprine and ovine samples. However, levels of PrPSc estimated from ELISA and immunohistochemistry assays were generally lower in goats than in sheep, although wide variation was noted in both species. Conclusions PrPSc accumulates in the shed placentas of goats with naturally acquired scrapie. Although these levels were low in most caprine samples, the caprine placenta may contribute to prion contamination of kidding facilities and transmission to co-housed sheep or goats.

  20. Effect of supplementing urea-treated sorghum stover with sesame cake or fishmeal on the body weight of sheep and cattle

    International Nuclear Information System (INIS)

    Feeding trials were carried out on-farm to examine the effect of supplementing urea-treated sorghum stover (UTSS) with sesame cake (SC) or fishmeal (FM) on the body weight (BWt) of sheep and cattle. Twenty one male sheep and nine Barka cattle were divided into three groups of seven sheep and three cattle in each trial. The trials were conducted at the same time, but on two different farms. The control diet consisted of UTSS fed ad libitum to both species of animals. The second and third diets were UTSS supplemented daily with SC or FM. The experimental period lasted for 90 d. Feed intakes and BWt were recorded regularly. The dry matter intake (DMI) in sheep was significantly different (P 0.05) from each other. The BWtG of cattle fed urea-treated sorghum stover alone was 559 g/head/d. This increased to 650 g/head/d with FM and to 741 g/head/d with SC supplementation. In cattle, BWtG was not significantly different (P>0.05) between the treatments. Feed conversion was best on SC followed by FM supplementation in both species (6.92 and 7.70 for sheep and 8.28 and 8.93 for cattle respectively). It can be concluded that feeding UTSS alone or supplemented with small amounts of SC or FM can increase the live weights of cattle and sheep at a reasonable cost. (author)

    The objective of this study was to monitor the viability during storage of Lactobacillus acidophilus LA-5 (A), Bifidobacterium animalis ssp. lactis BB-12 (B), and Streptococcus thermophilus CHCC 742/2130 (T) in probiotic cultured dairy foods made from pasteurized camel, cow, goat, and sheep milks fermented by an ABT-type culture. The products manufactured were stored at 4°C for 42d. Microbiological analyses were performed at weekly intervals. Streptococcus thermophilus CHCC 742/2130 was the most numerous culture component in all 4 products both at the beginning and at the end of storage. The viable counts of streptococci showed no significant decline in fermented camel milk throughout the entire storage period. The initial numbers of Lb. acidophilus LA-5 were over 2 orders of magnitude lower than those of Strep. thermophilus CHCC 742/2130. With the progress of time, a slow and constant decrease was observed in lactobacilli counts; however, the final viability percentages of this organism did not differ significantly in the probiotic fermented milks tested. The cultured dairy foods made from cow, sheep, and goat milks had comparable B. animalis ssp. lactis BB-12 counts on d 0, exceeding by approximately 0.5 log10 cycle those in the camel milk-based product. No significant losses occurred in viability of bifidobacteria in fermented camel, cow, and sheep milks during 6wk of refrigerated storage. In conclusion, all 4 varieties of milk proved to be suitable raw materials for the manufacture of ABT-type fermented dairy products that were microbiologically safe and beneficial for human consumption. It was suggested that milk from small ruminants be increasingly used to produce probiotic fermented dairy foods. The development of camel milk-based probiotic cultured milks appears to be even more promising because new markets could thus be conquered. It must be emphasized, however, that further microbiological and sensory studies, technology development activities, and

  2. Metabolic disposition of ivermectin in tissues of cattle, sheep, and rats

    International Nuclear Information System (INIS)

    The metabolic disposition of ivermectin, a new antiparasitic drug, has been studied in cattle, sheep, and also in rats dosed with the drug labeled with tritium in the C-22,23 positions. In the edible tissues of these animals, the unaltered drug was the major tissue residue component and was quantitated by HPLC-reverse isotope dilution assay. The depletion half-lives of the drug ranged between 1 and 6 days, similar to those of the total tissue residue in these species. Most metabolites present in the liver tissues were more polar than the parent drug. Based on spectral (NMR, mass spectrometric) analysis and chromatographic comparison with authentic compounds prepared by in vitro rat or steer microsomal incubations, three of these metabolites have been isolated and identified as the hydroxylation derivatives of ivermectin, i.e. 24-hydroxymethyl-H2B1a, its monosaccharide, and 24-hydroxymethyl-H2B1b

    Full Text Available This blinded field safety study was conducted in Senegal to assess safety and immunogenicity of administration of the registered dose of Rift Valley fever virus (RVFV Clone 13 vaccine (Onderstepoort Biological Products to sheep and goats of West African breeds under natural conditions. A total of 267 small ruminants (220 sheep, 47 goats were included; half received RVFV Clone 13 vaccine at the recommended dose and half received the diluent (as placebo only. The study was performed on three commercial farms in the northern and eastern region of Senegal in accordance with veterinary good clinical practices. The animals were observed daily for 3 days after vaccination, and then weekly for 1 year. In both sheep and goats vaccinated against RVFV seroconversion rates above 70% were recorded. No seroconversion related to RVFV was observed in placebo-treated animals. No statistically significant differences were determined between placebo and vaccinated groups for mean rectal temperatures for the first 3 days after administration (p > 0.05. No abnormal clinical signs related to treatment were noted, and only one slight injection site reaction was observed in one vaccinated animal for 2 days after vaccination. Out of 176 births assessed over 1 year (93 from the vaccinated group, 83 from the placebo group, 9 were abnormal in the placebo group and 3 in the vaccinated group (p > 0.05. The frequency of adverse events was similar in the placebo and vaccinated groups. RVFV Clone 13 vaccine administered according to the manufacturer’s instructions was safe and well tolerated in West African breeds of sheep and goats, including animals of approximately 6 months of age and pregnant females, under field conditions in Senegal. Antibody levels persisted up to 1 year after vaccination.

  6. Comparative responses of intake and rumen function in sheep and goats to supplementation of barley straw forages with urea and sulphur

    International Nuclear Information System (INIS)

    Goats and sheep were offered a low quality barley straw (0.72% N) with or without a urea (0.3% N of DM) and sodium sulphate (0.03% S of DM) supplement. There was little difference in apparent digestibility intake and digestible organic matter intake of barley straw between the control animals and the supplemented animals, or between the two species. This lack of difference may be due to the fact that the in vivo digestion of the straw (37% apparent DM digestibility) was close to its potential digestibility. Though the rumen ammonia concentration of goats was higher (P < 0.01) than that of sheep, the digestion rate of straw in the rumen was higher (P < 0.01) for sheep. It was concluded that higher rumen ammonia levels in goats did not confer any advantage to this species in terms of digestion rate and duodenal protein supply and that both species failed to respond to urea and sulphur supplementation.

    This study aimed to elucidate whether distinct endocrine and metabolic adaptations provide llamas superior ability to adapt to low protein content grass-based diets as compared with the true ruminants. Eighteen adult, nonpregnant females (6 llamas, 6 goats, and 6 sheep) were fed either green grass hay with (HP) or grass seed straw (LP) in a cross-over design experiment over 2 periods of 21 d. Blood samples were taken on day 21 in each period at -30, 60, 150, and 240 min after feeding the morning meal and analyzed for plasma contents of glucose, triglyceride, nonesterified fatty acids, β-hydroxy butyrate (BOHB), urea, creatinine, insulin, and leptin. Results showed that llamas vs sheep and goats had higher plasma concentrations of glucose (7.1 vs 3.5 and 3.6 ± 0.18 mmol/L), creatinine (209 vs 110 and 103 ± 10 μmol/L), and urea (6.7 vs 5.6 and 4.9 ± 0.5 mmol/L) but lower leptin (0.33 vs 1.49 and 1.05 ± 0.1 ng/mL) and BOHB (0.05 vs 0.26 and 0.12 ± 0.02 mmol/L), respectively. BOHB in llamas was extremely low for a ruminating animal. Llamas showed that hyperglycemia coexisted with hyperinsulinemia (in general on the HP diet; postprandially on the LP diet). Llamas were clearly hypercreatinemic compared with the true ruminants, which became further exacerbated on the LP diet, where they also sustained plasma urea at markedly higher concentrations. However, llamas had markedly lower leptin concentrations than the true ruminants. In conclusion, llamas appear to have an intrinsic insulin resistant phenotype. Augmentation of creatinine and sustenance of elevated plasma urea concentrations in llamas when fed the LP diet must reflect distinct metabolic adaptations of intermediary protein and/or nitrogen metabolism, not observed in the true ruminants. These features can contribute to explain lower metabolic rates in llamas compared with the true ruminants, which must improve the chances of survival on low protein content diets. PMID:26073222

  9. Diagnostic and control functions of the radioisotope methods for the reproduction management of cattle and sheep breeding

    International Nuclear Information System (INIS)

    The following applications of radioimmunoassay were studied: 1) for early diagnosis of pregnance in caws and sheep by determination of progesterone (PG) in milk and blood plasma via veterinary radioimmunological test STERON - RM125; 2) for diagnosis and treatment of ovarian disturbances in cows by RIA of luteinizing hormone (LH), follicle stimulating hormone (FSH) and PG in blood plasma; 3) for control of the biological efficiency of sheep estrus synchronisation with MAP (vaginal tampons) and Estrophan (PgF2α); 4) for control of the reproductive condition of rams and effect of Tribestan in treatment of different forms of impotention by RIA of testosterone in blood. It was established that the use of RIA objectified the process of decision-making in regulation of the reproduction deviations in ruminating farm animals by veterinary means. Conclusions are drawn and suppositions are made for introduction of the radioisotope methods in the reproduction control of cattle and sheep breeding in practice. 4 tabs.; 15 refs

  10. Blood Pb and δ-ALAD inhibition in cattle and sheep from a Pb-polluted mining area

    International Nuclear Information System (INIS)

    The effects of Pb pollution on cattle and sheep raised in an ancient mining area were studied through the use of blood Pb (PbB) levels and δ-aminolevulinic acid dehydratase (δ-ALAD) activity. Lead levels in livestock blood from the mining area (n = 110) were significantly elevated when compared to the controls (n = 79). In 91.4% of cattle (n = 58) and 13.5% of sheep (n = 52) sampled in the mining area, PbB levels corresponded to subclinical exposure (6–35 μg/dl). Two young cattle (35 μg/dl). Elevated PbB was also accompanied by δ-ALAD activity inhibition in blood, which confirms that measurable effects of Pb poisoning were taking place. Observed PbB levels suggest that a potential risk to human consumers of beef from the Pb polluted areas may also exist, as has been shown previously for game meat from the same mining area. - Highlights: ► We studied effects of Pb pollution on livestock raised in an old mining area. ► Livestock from the mining area had higher blood Pb levels than the controls. ► Pb levels were higher in cattle than in sheep. ► Pb exposure inhibited δ-aminolevulinic acid dehydratase, especially in cattle. ► Lead uptake in livestock reared in this area poses a risk to human consumers. - Lead from an ancient mining area still affects livestock health and compromises the safety of derived food products.

    Peste des petits ruminants (PPR) is a contagious and often fatal transboundary animal disease affecting mostly sheep, goats and wild small ruminants. This disease is endemic in most of Africa, the Middle, Near East, and large parts of Asia. The causal agent is peste des petits ruminants virus (PPRV), which belongs to the genus Morbillivirus in the family Paramyxoviridae. This genus also includes measles virus (MV), canine distemper virus (CDV) and rinderpest virus (RPV). All are closely related viruses with serological cross reactivity. In this study, we have developed a Luciferase Immunoprecipitation System (LIPS) for the rapid detection of antibodies against PPRV in serum samples and for specific differentiation from antibodies against RPV. PPR and rinderpest (RP) serum samples were assayed by PPR-LIPS and two commercially available PPR cELISA tests. The PPR-LIPS showed high sensitivity and specificity for the samples tested and showed no cross reactivity with RPV unlike the commercial PPR cELISA tests which did cross react with RPV. Based on the results shown in this study, PPR-LIPS is presented as a good candidate for the specific serosurveillance of PPR. PMID:26506137

    Full Text Available Aim: To monitor the effect of nutrition and pregnancy on oxidative status of animals under the arid condition of South Sinai. Materials and Methods: Blood samples were taken from two groups of animals: The first group retained in farm and fed on concentrate (high diet and another group grazing natural forage (low diet. Each group was subdivided into pregnant and non-pregnant animals. Blood samples were assayed for their content of malondialdehyde (MDA, total antioxidant capacity (TAC, catalase (CAT, and superoxide dismutase (SOD enzymes. Results: MDA level significantly increased in pregnant animals fed either concentrate or grazing low-quality forage and accompanied by a low level of TAC in pregnant grazing animals fed low-quality forage. The activity of CAT decreased in pregnant fed either concentrate or grazing and SOD significant decrease in the pregnant grazing group. These data suggested that the animals might have experienced some degree of oxidative stress and lipid peroxidation and indicating that redox homeostasis was impaired in those pregnant and specially fed on forage rations. Conclusion: Pregnancy constituted the most oxidative stress facing the grazing and concentrated diet feed sheep and goats under arid and saline conditions of Southern Sinai, Egypt.

    Full Text Available The objective of this study was to compare the metapodial lengths of sheep and goats measured with a caliper with those measured using a 2-dimensional digital method. Complementarily, the lengths of medial and lateral metapodials in these species were compared. The limbs of 30 ewes and 30 goats were used. After preparation, the lateral and medial length of the metacarpals and metatarsals were measured twice with a caliper. Afterwards, each bone was scanned and the same lengths were digitally measured twice using commercial software. Data analysis revealed strong linear relationship between the two methods but the absolute relative deviation of the measurements with the caliper was significantly higher than those with the 2-dimensional method (P<0.05. All lengths measured with the caliper were significantly higher compared to those measured with the 2-dimensional method (P<0.05. In goats, the lateral length of both metacarpals and metatarsals was significantly higher than medial length (P<0.05; in sheep the lateral length was significantly higher compared to the medial one only in metatarsal bones (P<0.05. In conclusion, the 2-dimensional method is more accurate for the measurement of the metapodials’ length than the caliper and there is asymmetry between the medial and lateral metapodials in these species.

    Reproductive failure has a negative impact on animal production, health and welfare and ultimately rural economies. In Ethiopia, the factors affecting small ruminant reproductive efficiency are inadequately investigated. A cross-sectional survey was done from November, 2010 to May, 2011 to investigate risk factors of reproductive failures including Toxoplasma gondii infection. Analysis of 1372 sera (787 sheep and 585 goats) from 409 flocks using ELISA showed high flock (59.7%) and animal (31.8%) level T. gondii seroprevalence. An overall 24.9% (341/1372) annual abortion rate (19.6% in sheep and 32.0% in goats) was recorded. Animal level T. gondii seroprevalence was significantly associated with abortion in Ambo and Ada'a-Liben districts (Odds ratio [OR] = 2.31, 95% confidence interval [CI]: 1.42, 3.76; P = 0.001). Questionnaire survey on 199 households of Ambo, Ada'a-Liben and Fentale districts revealed high flock level abortion (57.5%), still birth (28.9%) and neonatal losses (47.9%), which are significantly different between study districts (Pwater from river and stagnant water bodies, grazing/browsing in plain land and extensive management were significant predictors of flock level reproductive failures. In the final Zero inflated Poisson regression model number of abortions was significantly higher in goat than in sheep flocks (Incidence risk ratio [IRR] = 1.42, 95% CI: 1.08, 1.87; P = 0.012). It is also significantly higher in pastoral (IRR = 1.81, 95% CI: 1.16, 2.83; P = 0.008) and agro-pastoral production systems (IRR = 1.94, 95% CI: 1.32, 2.86; P = 0.001) than in sedentary production system. Prevention of toxoplasmosis, improved husbandry practices and further epidemiological studies to identify causes of reproductive failures are recommended. PMID:24011595

    A total of 1502 samples, including feces of sheep (793) and cattle (348), pasture soil (118), dung compost (147) and barn soil (96), were examined between October 2012 and August 2014 to discover potential strains of nematophagous fungi for the biological control of livestock-parasitic nematodes. These samples were collected from 87 sites located in 48 counties of 20 provinces (autonomous regions/municipalities) of China. Fungi were identified down to a species level. Four hundred and seventy-seven isolates, which were distributed in 8 genera and 28 taxa, were identified as nematophagous fungi. Nematode-trapping fungi included 17 species and one unidentified species of Arthrobotrys, two of Dactylella, Drechslerella dactyloides, and Duddingtonia flagrans. Five identified species and two unidentified species of endoparasitic fungi were isolated. The predominant species from all regions were Arthrobotrys oligospora, followed by Arthrobotrys musiformis, Arthrobotrys (Monacrosporium) thaumasiun, and Arthrobotrys (Monacrosporium) microscaphoides. Species with adhesive networks were the most frequently isolated. Among the endoparasitic fungi, Podocrella harposporifera (Harposporium anguillulae) was the most common species, followed by Harposporium lilliputanum and Harposporium arcuatum. Based on Shannon diversity index, the diversity levels of nematophagous fungi were relatively higher in samples associated with cattle, barn soil, and subtropical monsoon climate zone. Three species isolated from this study, namely, Duddingtonia flagrans, Arthrobotrys salina (Monacrosporium salinum), and Arthrobotrys oligospora var. sarmatica, are newly recorded in China, and 20 species (including one unidentified species) are newly recorded in sheep and cattle barn soils worldwide.

    Full Text Available Transhumance connects highlands and lowlands creating that way a farming system with important social, cultural, economic, landscape and environmental effects. Despite the continuous reduction of the number of transhumant herds in Greece the later years, this farming system still preserves a considerable position in country’s animal husbandry. Aim of this paper is the study of management practices and the nomination of productivity indicators of the transhumant reared animals in the region of Sterea Ellada. The necessary data were collected through a specially conducted questionnaire from totally 140 transhumant herders. The results reveal average herd size of 364.40, with herd sizes that excides one thousand, especially for goat herds, and residence on mountainous, semi-mountainous areas for at least 5 months. The main source of income is the trade of milk, but it should be noted that a small proportion of the herders process milk and trade only feta and/or other traditional kinds of cheese complementary of meat trade. In addition average traded milk production and prolificacy reveal the influence of more intense farming practices, such as crossbreeding and/or rational feed and the continuous effort of the producers and correspond to consecutive increase of the needs of the market.

    The aim of this study was to determine the transmission routs of Listeria spp. in dairy farms manufacturing fresh cheese made from ovine and caprine raw milk and to evaluate the impact of Listeria monocytogenes mastitis on raw milk contamination. Overall, 5,799 samples, including 835 environmental samples, 230 milk and milk product samples, and 4,734 aseptic half-udder foremilk samples were collected from 53 dairy farms in the dairy intensive area of Lower Austria. Farms were selected for the study because raw milk was processed to cheese that was sold directly to consumers. A total of 153 samples were positive for Listeria spp., yielding an overall prevalence of 2.6%; L. monocytogenes was found in 0.9% of the samples. Bulk tank milk, cheese, and half-udder samples were negative for Listeria spp. Because none of the sheep and goats tested positive from udder samples, L. monocytogenes mastitis was excluded as a significant source of raw milk contamination. L. monocytogenes was detected at 30.2% of all inspected farms. Swab samples from working boots and fecal samples had a significantly higher overall prevalence (P milk processing environment (7.9%). A significant correlation was found between the prevalence of L. monocytogenes in the animal and in the milk processing environment and the silage feeding practices. Isolation of L. monocytogenes was three to seven times more likely from farms where silage was fed to animals throughout the year than from farms where silage was not fed to the animals.

    Polyclonal capture enzyme-linked immunosorbent assay (PC-ELISA), monoclonal capture ELISA (MC-ELISA), mouse neutralization test (MNT), and counterimmunoelectrophoresis (CIEP), were compared for their ability to detect epsilon toxin in intestinal contents and body fluids of sheep and goats. When used to evaluate intestinal contents of sheep artificially spiked with epsilon prototoxin, PC-ELISA detected 0.075 mouse lethal dose (MLD)50/ml, whereas the MNT, MC-ELISA, and CIEP detected 6, 25, and 50 MLD50/ml, respectively. Amounts of epsilon toxin detected by PC-ELISA, MC-ELISA, MNT, and CIEP in sheep pericardial fluid artificially spiked with epsilon prototoxin were 0.075, 0.75, 6, and 200 MLD50/ml, respectively. For assaying epsilon toxin in aqueous humor, PC-ELISA and MC-ELISA detected 0.075 MLD50/ml, whereas CIEP detected 200 MLD50/ml (MNT was not evaluated). When 51 samples of intestinal contents of sheep and goats (32 positive and 19 negative to MNT) were analyzed by the other 3 techniques, the relative sensitivity of PC-ELISA, MC-ELISA, and CIEP was 93.75, 84.37, and 37.50%, respectively. The specificity of PC-ELISA, MC-ELISA, and CIEP was 31.57, 57.89, and 84.21%, respectively. The absolute sensitivity of PC-ELISA, MC-ELISA, CIEP, and MNT was 90.90, 69.69, 15.15, and 54.54%. The absolute specificity of the 4 techniques was 100%. These results show that there is a marked inconsistency among techniques routinely used to detect Clostridium perfringens epsilon toxin. Until more consistent results are achieved, the diagnosis of enterotoxemia should not only be based solely on epsilon toxin detection, but also on clinical and pathological data. PMID:12661718

    Full Text Available Caseous lymphadenits (CL is a chronic and subclinical disease that affects goats and sheep and, consequently, causes economic losses, especially to small producers. The purpose of this study, through use of Polymerase Chain Reaction (PCR, was to verify the presence of virulence genes of phospholipase D (PLD, integral membrane protein (FagA, iron enterobactin transporter (FagB, ATP binding cytoplasmic membrane protein (FagC and iron siderophore binding protein (FagD in 168 isolates of C. pseudotuberculosis obtained from cases of caseous lymphadenitis in goats and sheep. FagA, FagB and PLD genes were detected in all 145 strains isolated from abscesses in superficial lymph nodes and in 23 strains isolated from viscera. The FagC gene was positive in 167 (99.40% isolates. The FagD gene was detected in 160 (95.23% isolates. All virulence factors analyzed were found more frequently among isolates collected in the viscera of animals with CL, indicating a multifactorial nature, as well as variations, in the invasive potential of C. pseudotuberculosis strains.

    This study investigated the prophylactic action of the chemical combination zeta-cypermethrin and piperonyl butoxide, administered by means of slow-release insecticide-impregnated ear tags, against biting midges (Culicoides spp) attacking sheep and against midges, horn flies (Haematobia irritant), stable flies (Stomoxys calcitrans), and houseflies (Musca domestica) attacking cattle. Treated sheep and cattle were protected 100 percent against blood-feeding midges for two months and there was a clear reduction in the number of midges collected from treated animals. Three days after the ear tags were attached to cattle, the number of horn flies on the cattle was reduced to practically zero and remained at a low level until the end of the trial (day 85). There was also a strong reduction in the numbers of stable flies and houseflies counted. PMID:22930983

  6. Antibody response in cattle, sheep and rats to infection with γ-irradiated metacercariae of Fasciola hepatica

    International Nuclear Information System (INIS)

    Cattle, sheep and rats were infected orally with γ-irradiated metacercariae of Fasciola hepatica, or with normal metacercariae. The antibody response was monitored in each host to metacercarial tegument (T0), juvenile tegument (T1), adult tegument (T2) and gut antigens. The response was examined at weekly intervals for cattle and sheep throughout 15 weeks of infection and four weeks after infection in rats, using an indirect fluorescent antibody labelling technique. It was found that the irradiated metacercariae engendered a normal humoral response to T0, T1 and gut antigens in all three hosts although the antibody levels were somewhat reduced due to early death or stunting of the flukes. T0 and T1 appeared to be antigenically similar. Antibodies against T2 appeared late in the animals infected with γ-irradiated metacercariae and the titres attained were considerably lower than in the controls. The T2 antigen stimulus in the animals given γ-irradiated metacercariae was probably provided by flukes which 'broke through' the developmental barrier imposed by irradiation and which were found alive at autopsy.

    Bovine digital dermatitis (BDD) is an infective foot disease commonly reported in dairy cattle where Treponema are considered as the primary causative infectious agents. There still remains little definitive information on the etiology of BDD in beef cattle suggesting further investigations are warranted. Beef BDD lesions (n=34) and healthy beef foot tissues (n=38) were analysed by PCR for three BDD-associated Treponema phylogroups and also for Dichelobacter nodosus and Fusobacterium necrophorum. Spirochete culture was attempted on all BDD lesion samples. One or more BDD-associated Treponema phylogroups were detected in 100% of beef BDD lesions. "Treponema medium/Treponema vincentii-like", "Treponema phagedenis-like" and Treponema pedis spirochetes were identified in 27/34 (79%), 31/34 (91%) and 24/34 (71%) of BDD lesions, respectively. No BDD-associated treponeme DNA was amplified from beef healthy foot tissues. D. nodosus and F. necrophorum were present in 24/34 (71%) and 15/34 (44%) of lesions and 10/38 (26%) and 12/38 (32%) of healthy foot tissues, respectively. Twenty spirochetes were isolated from beef BDD lesions; 19 were representatives of the three BDD-associated Treponema phylogroups. One spirochete isolate shared less than 97% 16S rRNA gene similarity to the three cultivable BDD-associated Treponema phylogroups and therefore may represent a novel taxa of Treponema. Upon comparison, sheep contagious ovine digital dermatitis (CODD), dairy cattle and beef cattle BDD lesions appear to have extremely similar bacteriological data and therefore provides evidence of a shared etiopathogenesis posing concerns for cross-species transmission.

    The goat population in Thailand is relatively small. However the past 10 years, has seen a marked increase due to an increased demand for goat meat and milk. In the past, the numbers of research publications concerning goats in Thailand were small, especially dairy goats compared with those in other economical livestock such as swine, cattle and poultry. However, the numbers have gradually increased owning to the promotion of goat production by the government. Major research areas have been f...

    Full Text Available Introduction & Objective: 130 heteroxenous species of sarcosytis with different life cycle and pathogenesis have been recognized. The pathogenic species for humans are S. hominis from cattle and S. suihominis from pig that humans are definitive and cattle and pig are intermedi-ate hosts. Some species of Sarcocystis can cause important economic loss and disease in livestock, and health issues in humans. The aim of this study was to determine the prevalence of Sarcocystis infection in slaughtered Cattle and sheep in Hamadan, west of Iran. Materials & Methods: In this cross sectional descriptive study a total of 324 cattle and 334 sheep carcasses were examined using naked eye inspection for macroscopic Sarcocysts, and digestion method, for microscopic types of parasite. Muscles from thigh, heart, tongue, esophagus, diaphragm and costal muscles were examined. All carcasses examined by naked eyes and tissues were minced and poured in digestion medium separately and sediment was examined microscopically. Results: The prevalence of microscopic Sarcocystis in cattle was detected in 100% and there was no macroscopic cyst in examined carcasses. However, the prevalence of microscopic Sarcocystis in the sheep was also 100% and the sarcocysts were found in the 48.34 % of esophagus and 29.49% of diaphragm muscles by naked eyes inspection. Conclusion: The digestion is found the most sensitive method for diagnosis of Sarcocystis. Al-though 100% of muscles were found infected but the majority of the cysts in the sheep and all in the cattle were as microcysts. That means, the meat should be cooked sufficiently irrespec-tive of meat inspection results. (Sci J Hamadan Univ Med Sci 2015; 22 (3: 210-216

    As there is a massive increase of livestock husbandry in semi-arid and arid landscapes, the investigation of trampling-induced soil erosion has become indispensable for a better understanding of erosive processes such as loosening and translocation of sediment, as well as the genesis of rill erosion and gully systems. Our work will support other studies focusing on desertification and land-use changes in the investigated landscapes. Up to this date, research on livestock-induced soil erosion, even in relation to other erosion processes such as aeolian and fluvial/pluvial sediment translocation, is very scarcely found in literature. The presented study on trampling-induced soil erosion by sheep and goats in arid and semi-arid landscapes aims to create a general understanding, an estimation and quantification of the influencing factors of these erosive processes. Within this study, we present the first results of several field rainfall experiments on rock fragment translocation as well as loosening and transportation of coarse and fine sediment depending on the motion sequence and the individual weight, size, and hoof beat of the animals. Furthermore, we conducted additional experiments to investigate the trampling-induced erosion processes for various other sediments, especially those in the range of clay, silt, and sand. To do so, we used a specially designed test plot, equipped with sediment traps on each side. For a clear and reliable analysis of the measured parameters, univariate as well as multivariate statistical methods have been used. For all field methods, we developed relevant statements concerning flock size. The rock fragment translocation experiments done so fare have shown that a flock of 45 sheep or goats moved 87 % of 320 spread out rock fragments with a mean translocation distance of 0.123 m when trampling across a test plot of 3.2 m^2. Besides that we found out that the soil surface was worked up in a way that the loosened fine sediment proved to

    Bracken fern (Pteridium aquilinum) is a worldwide plant containing toxic substances, which represent an important chemical hazard for animals, including humans. Ptaquiloside, 1, a norsesquiterpenoid glucoside, is the major carcinogen of bracken detected in the food chain, particularly in the milk from farm animals. To date, ptaquiloside has been shown in the milk of cows feeding on a diet containing bracken fern. This is the first study that shows the systematic detection of ptaquiloside, 1, and reports its direct quantitation in pooled raw milk of healthy sheep and goats grazing on bracken. Ptaquiloside, 1, was detected by a sensitive method based on the chemical conversion of ptaquiloside, 1, into bromopterosine, 4, following gas chromatography-mass spectrometry (GC-MS) analysis. The presence of ptaquiloside, 1, possibly carcinogenic to humans, in the milk of healthy animals is an unknown potential health risk, thus representing a harmful and potential global concern of food safety.

    Peste des petits ruminants virus (PPRV) is causing infectious disease with high morbidity and mortality rate in domestic and wild small ruminants of Pakistan with valuable economical losses. The present study was carried out to investigate risk factors of PPRV in domestic small ruminants which were present in the vicinity of wildlife parks. A total of 265 sera samples (27 wild ruminants and 238 domesticated small ruminants) from apparently healthy animals from two different wildlife parks were collected and analysed for PPRV antibodies. Also, 20 nasal swabs from domestic small ruminants showing respiratory signs were collected to check for presence of PPRV antigen. Competitive ELISA revealed highest proportions of anti-PPRV antibodies in domestic small ruminants around the Wildlife Park at Lahore (35%) as compared to Faisalabad (13%), with no existence of PPRV antibodies in tested serum of wild ruminants at these parks. Higher seropositivity was observed in females (25.6%) than in males (5.1%) and in goats (34.5%) compared to sheep (11.2%). The results of N-gene based RT-PCR highlight the absence of PPRV due to lack of current PPR outbreak in the region during study period. Even though grazing was not a significant risk factor, there is still a possibility of wildlife-livestock interactions for feed and water reservoirs, resulting in spillover of PPR to wildlife. Keeping in view the high seropositivity and risk of PPR, vaccination should be adopted to avoid circulation of PPRV among wild and domestic small ruminants (sheep and goats). PMID:27294134

    This study was carried out to determine the presence and frequency of Anaplasma ovis and Anaplasma marginale in sheep and dairy cattle in West-Azerbaijan province, Iran. A total number of 200 blood samples were randomly collected via the jugular vein from apparently healthy cattle (100) and sheep (100). The extracted DNA from blood cells was screened using genus-specific (Anaplasma spp.) nested-polymerase chain reaction (PCR) based on 16S rRNA gene primer sets. Species-specific PCR was set up using major surface protein 4 (MSP4) gene primer set. None of cattle blood samples were positive for Anaplasma spp. by the first nested PCR. Five samples among the 100 sheep blood samples were both positive in the first nested PCR and A. ovis -specific PCR, based on MSP4 gene. In total, 5.00% of animals were A. ovis positive. This study identified a low prevalence of A. ovis in the blood of apparently healthy sheep in West Azerbaijan province. PMID:27482362

    Gastrointestinal nematodes (GIN) are increasingly resistant to anthelmintic drugs worldwide, so integrated control methods are more and more needed for the sustainability of small ruminant farming. Such methods rely on knowledge in epidemiology, physiology, and genetics. Ecological studies have highlighted the effect of host density on parasite populations, and in the humid tropics, rotational grazing systems were designed according to the survival of GIN free-living stages. This study aimed to assess the effects of mixed stocking and host stocking rate on host GIN infection level. Four groups of 15-17 Creole male kids were raised on irrigated pasture from weaning (about 3 months) until the age of 7 months, at four partial stocking rates (pSR): 100% (control), 75% (G75), 50% (G50), and 25% (G25) of the total stocking rate of the pasture. The last three groups were associated with weaned Creole heifers to obtain the same overall stocking rate as the control. Animals grazed in a 'leader' goat and 'follower' cattle design: the G25, G50, and G75 paddocks were split into six plots; each plot was grazed by goats for 1 week and by heifers the following week. The pasture then rested for 4 weeks before the animals were returned for a new grazing sequence. Five control plots were grazed rotationally for 1 week, and rested for 4 weeks. This design was repeated three times a year for a total of 10 repetitions. Average faecal egg counts (FEC) decreased according to a power function of the pSR: FEC=1829pSR(3.7). The observed death rate decreased significantly with the pSR (27.6%, 16.4%, 11.9%, and 12.2%). The kids grew faster in G25 (51 g d(-1)) than in G50 (43 g d(-1)) and G75 or control (32 g d(-1), p<0.05). Heifers were not significantly infected with GIN and grew normally (about 0.48 kg d(-1)). Reducing the pSR by associating a non-host species in a rotational stocking system may be a very promising component of integrated GIN control, at least for the humid tropics. PMID

    Full Text Available Forage supply from herbs was assessed in a thinned Caatinga enriched with buffel grass (Cenchrus ciliaris L. exposed to goat and sheep grazing. The 2.4 ha experimental area, located at the Experimental Station of the Federal University of Campina Grande, in Santa Terezinha, Paraíba State, Brazil, was divided into four 0.6 ha paddocks, which were further subdivided into two 0.3 ha experimental plots. Twelve F1 (Boer x SRD goats and 12 Santa Inês sheep were divided in four groups of six animals of the same species. The herbaceous vegetation was separated into buffel grass (Cenchrus ciliaris L., dicotyledons and other grass species. Treatments were randomized to plots according to a completely random design with two treatments, four replications, with measures repeated in time (July/1, Aug/1, Sept/1 and Oct/1. Buffel grass dry mater (DM availability was higher in the sheep grazed than in the goat-grazed area. Buffel grass DM supply did not change from July to September, while dicotyledons DM supply decreased. Grazing affected availability, accumulation rate and supply of the forage produced (DM basis by dicotyledonous herbs. Buffel grass forage availability was not affected during the experimental period.

    A questionnaire of 15 questions was completed by four categories of respondents with the aim of establishing the experience and opinions of these groups on the constraints including animal health problems for communal, small-scale sheep and goat farming in the Eastern Cape province of South Africa. The questionnaires were completed independently and categories were representative of the areas investigated. Analysis of responses was done by means, ranges, votes and clusters of responses. Comparisons between the responses of the four categories were made to identify similarities or contrasts. The results revealed that of non-veterinary concerns, stock theft was the major problem for these farms. Nutrition was a further major constraint. A third area of significant concern was the provision or availability of facilities like fences, water troughs, dips and sheds. Lack of marketing and business skills were also seen as important deficiencies to be rectified so as to promote profitable farming. Of the most important veterinary problems identified, the provision, availability, cost and care of drugs and vaccines were seen as major stumbling blocks to effective disease control, as well as lack of access to veterinary services. The most important diseases that constrain small-ruminant livestock farming in the farming systems investigated were sheep scab and other ectoparasites, heart water, enterotoxaemia, internal parasites and bluetongue. A lack of knowledge in key areas of small-stock farming was revealed and should be rectified by an effective training and support programme to improve the contribution of small-ruminant farming to livelihoods in these communities.

    A temperature-sensitive shuttle vector, pBB80C, was utilized to generate in-frame deletion mutants of the leukotoxin structural gene (lktA) of Mannheimia haemolytica serotypes 1, 2, 5, 6, 7, 8, 9, and 12. Culture supernatants from the mutants contained a truncated protein with an approximate molecular weight of 66 kDa which was reactive to anti-leukotoxin monoclonal antibody. No protein reactive to anti-LktA monoclonal antibody was detected at the molecular weight 100-105 kDa of native LktA. Sheep and goats vaccinated intramuscularly with a mixture of serotypes 5 and 6 mutants were resistant to virulent challenge with a mixture of the wild-type parent strains. These vaccinates responded serologically to both vaccine serotypes and exhibited markedly-reduced lung lesion volume and pulmonary infectious load compared to control animals. Control animals yielded a mixture of serotypes from lung lobes, but the proportion even within an individual animal varied widely from 95% serotype 5-95% serotype 6. Cultures recovered from liver were homogeneous, but two animals yielded serotype 5 and the other two yielded serotype 6 in pure culture. PMID:24021458

    Full Text Available The quality of goat meat has recently become an important aspect in the marketing of goats in Serbia. The aim of this study was to compare some goat meat quality parameters of various races and to determine the differences between them. Goat breeds were Balkan goat and Serbian White goat, both female in the age of four years. Analysis of quality parameters: chemical composition (moisture, protein, total fat, ash,, pH value, fatty acids, amino acids, microelements content, tenderness, cooking loss and colour measurements were done. Statistically significant difference was found between the samples of two groups of goat meat (P <0.05 in relation to: live weight (kg, water (%, fat (%, protein (%, ash (%, among 11 of 15 tested fatty acids, amino acid leucin, sensory examination of fresh meat for the palpatory evaluated firmness and in the content of copper and zinc. Statistically significant differences between the groups did not existed regarding the pH value, fatty acids eicosenoic, cis-heptadecenoic, t-elaidic, t-linolelaidic and amino acids alanine, arginine, aspartic acid, cysteine, glutamic acid, glycine, histidine, isoleucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine. Also there was no statistically significant difference in instrumental testing of the meat color, sensory evaluation of surface color, visual evaluated structure, olfactory evaluated odor and iron and manganese. These results suggest that the race of animal has an impact on meat quality. [Projekat Ministarstva nauke Republike Srbije, br.

    Full Text Available Acute Lantana camara poisoning in a Boer goat kid is described. The animal was part of a flock of boer goats that was introduced from the Kalahari thornveld, where the plant does not occur, to an area where the plant grew abundantly. At necropsy, the animal was severely icteric, dehydrated and constipated, with hepatosis, distention of the gall-bladder and nephrosis, but no skin lesions. Histopathological findings of the liver confirmed moderate hepatosis with single-cell necrosis and bile stasis. The pathology is consistent with that described in acute Lantana poisoning in cattle, sheep and goats. The absence of photosensitisation may be attributed to relatively mild liver damage, or the rapid course of this toxicosis.

    Full Text Available The present study was planned to carry out a seroprevalence study of PPR antibodies in North West Frontier Province (NWFP including Federally Administered Tribal Areas (FATA, using competitive-ELISA (c-ELISA kit. A total of 4548 serum samples collected from 26 locations of the NWFP including. Eight hundred twenty eight samples were found positive for PPR antibodies yielding an overallseroprevalence of 18.20 percent in the small ruminant population included in the study. 337 (24.90% serum samples from sheep and 491 (15.36% from goats were found positive in PPR c-ELISA yielding a marginal difference in seroprevalence of PPR.  The current situation of PPR in Pakistan could be regarded as of low magnitude but constant threat. Incidence may increase to the alarming level due to uncontrolled/ free movement within and from across boarders to the stocks of non-immunized susceptible population of sheep and goats in the country but production systems and economic realities constraint the effective animal movement control within and across the boarders. Based on the limited reports of outbreaks and uneven distribution of occurrence over the years of past decade, the best available options are high level of prevention and objective surveillance. Keeping in view the high risk of PPR, control strategy should be adopted and further study needs to be undertaken to ascertain the extent of PPR virus circulating in the population of goats and sheep in the country. Under existing production and marketing system, sanitation and preventive vaccination are two practicable options for control of PPR in Pakistan. Homologous PPR vaccine is now available which is a freeze dried live vaccine derived from tissue culture from attenuated PPR virus. The vaccine is intended for sheep and goats and is required to be injected to all animals above the age of 3 month. The vaccine may be repeated after one year of the primary vaccination in high risk areas. [Vet World 2009

    In small ruminants, the response against gastrointestinal nematode (GIN) infections is influenced not only by the host genotype and the physiological stage but also by environmental factors, particularly the nutritional status at the time of infection. In this study we evaluated the long-term effect and the interaction between the host species and the nutritional history on the response to GIN infection in two animal models differing in their phenotypic growth and their level of GIN resistance: Black Belly sheep and Creole goats. Lambs and kids were subjected to three distinct nutritional conditions at weaning: low dietary conditions (100% of the theoretical energy requirement for maintenance, corresponding to 548v. 484KJ/Kg BW(0.75) for lambs and kids respectively and 6% of crude protein, CP), medium dietary conditions (150% of the theoretical energy requirement for maintenance and 13% CP) and high dietary conditions (200% of the theoretical energy requirement for maintenance and 20% CP). This 3-months period was followed by a 1-month period on the medium dietary conditions for all the animals before an experimental Haemonchus contortus infection. We monitored the impact of the nutritional history (nutritional condition after weaning), on the intensity of the GIN infection by measuring individual faecal egg counts (FEC), growth rate (ADG), blood eosinophil counts and other pathophysiological parameters. The FEC, growth rate and blood eosinophil counts were significantly affected by the nutritional history in lambs but not in kids. The lowest FEC was found for lambs placed in high dietary conditions, however during the same period body weight loss was observed in this group. In low dietary conditions, kids were more resistant than lambs and the ADG was higher in lambs. However, the anaemia and the level of serum pepsinogen, marker of the abomasal mucosa integrity, were higher in kids. Our data suggest that the impact of the post-weaning nutritional history on the

    Due to the development of anthelmintic resistance, there have been calls for more sustainable nematode control practices. Two important concepts were introduced to study and promote the sustainable use of anthelmintics: targeted treatments (TT), where the whole flock/herd is treated based on knowledge of the risk, or parameters that quantify the severity of infection; and targeted selective treatments (TST), where only individual animals within the grazing group are treated. The aim of the TT and TST approaches is to effectively control nematode-induced production impacts while preserving anthelmintic efficacy by maintaining a pool of untreated parasites in refugia. Here, we provide an overview of recent studies that assess the use of TT/TST against gastrointestinal nematodes in ruminants and investigate the economic consequences, feasibility and knowledge gaps associated with TST. We conclude that TT/TST approaches are ready to be used and provide practical benefits today. However, a major shift in mentality will be required to make these approaches common practice in parasite control. PMID:25217603

    Schmallenberg virus (SBV) is a novel Orthobunyavirus within the family Bunyaviridae belonging to the Simbu serogroup. Schmallenberg virus infects ruminants and has since its discovery in the autumn 2011 been detected/spread to large parts of Europe. Most bunyaviruses are arboviruses, and SBV has been detected in biting midges in different European countries, suggesting that they may play a role in the transmission of the virus. It is not known how SBV was introduced to Europe and if SBV is pr...

    Directory of Open Access Journals (Sweden)

    A O Sonibare

    Full Text Available The survival and infectivity of indigenous isolates of Haemonchus contortus and in vitro cultivated infective larvae (L3 were studied. Active motile gravid females, adult and immature parasites were morphologically and morphometrically characterized and isolated from Haemonchus infected goats. These were subsequently inoculated into the abomasum of parasite free lambs through left sided laparatomy for production of fertile eggs to be used for coproculture. Harvested faeces from these lambs were cultured in a nutritive medium and kept in the incubator at 320C and room temperature 24-280C to obtain in vitro cultivated L of H. contortus. The infectivity and survival of in vitro cultivated L3 stored in refrigerator at 4-80C and under room temperature 24-280C were evaluated. Incubation period of 3 coproculture was observed to be shorter in medium at 320C than under room temperature 24-280C. The storage of in vitro cultivated L under different temperature range showed that the quantity of active larvae in a given volume 3 decreased at p<0.05 from the 5th day under 24-280C while at 4-80C became significantly lower from 20th day. Infectivity of isolate kept at 4-80C was sustained for 18-20 days while at 24-280C it was maintained for 10-12 days. Laboratory invitro cultivated L of H. contortus had limited infectivity and larvae mortality increase with time under different 3 temperatures. [Vet. World 2011; 4(12.000: 533-536

    There is a growing recognition that infections of livestock by the obligate intracellular bacterium, Chlamydia pecorum, are more widespread than was previously thought. A range of diseases have been associated with this pathogen, with the most important manifestations including infectious arthritis, infertility, enteritis, reduced growth rates, mastitis, and pneumonia. C. pecorum infections have also been associated with sub-clinical disease, highlighting our lack of knowledge about its true economic impact on livestock producers. Diagnosis of C. pecorum infection is based on clinical findings, serology and histopathology, which are not necessarily implemented in subclinical or early stages of infection, thus potentially contributing to under-diagnosis and under-reporting of infections associated with this bacterium. Recent molecular epidemiology studies have revealed that C. pecorum is genetically diverse and that there may be an association between certain strains and disease in sheep and cattle. Antimicrobial treatment of affected animals has questionable efficacy, justifying development of chlamydia vaccines for livestock. This review summarises current knowledge of the prevalence and impact of C. pecorum infections in sheep and cattle and provides an update on attempts to improve detection, management and treatment of infections by this important obligate intracellular pathogen.

    Full Text Available Goats and sheeps present an ectoparasite diversity that may result in considerable losses in these animals productivity. Fifteen agrarian reform settlements were visited, with the purpose of identifying ectoparasites in goats and sheeps, in which scraping, direct exams, and auricle exsudate collections were carried out. From the 494 examined goats, 89.87% had ectoparasites, as well as 232 sheeps, 76.72%. The arthropods identified in the goats were: Bovicola caprae (80.76%, Rhipicephalus microplus (1.01%, Cochliomyia hominivorax larvae (0.6%, Psoroptes cuniculi (0.4%, and Ctenocephalides felis (3.23%, Amblyomma parvum (1.01% and Linognathus stenopsis (0.2% which were described for the first time in Brazilian northeast. Mixed parasitism of B. caprae with R. microplus (0.46% and P. cuniculi with B. caprae (0.23% was also identified. In sheeps, B. ovis (74.5%, R. microplus (0.86%, C. hominivorax larvae (0.43% and A. parvum (0.43% were the ones registered for the first time, in this species, in Brazilian northeast, besides the association of B. ovis with R. microplus (0.56%. There was no association between gender and age (P>0.05. The development of studies to evaluate the ectoparasite importance as a limiting factor to animal production becomes important.

    Full Text Available Estudaram-se os efeitos do pastejo alternado de ovinos e bovinos e do pastejo rotacionado sobre o controle da verminose em ovelhas. Utilizou-se uma área experimental composta por três módulos de 1,67ha cada. Os módulos foram subdivididos em oito piquetes. Vinte ovelhas foram colocadas no módulo 1 e quatro bovinos adultos no módulo 2. Os animais permaneceram em cada piquete do módulo por cinco dias, totalizando 40 dias de permanência em cada módulo. Ao final desse período, as ovelhas foram transferidas para o módulo onde estavam os bovinos e estes para o módulo onde estavam os ovinos, mantendo esse esquema até o final do experimento. Um grupo-controle de 20 ovelhas foi mantido, também em sistema rotacionado, em um terceiro módulo, sem compartilhar a pastagem. As ovelhas submetidas ao manejo com bovinos apresentaram o menor grau de infecção por nematódeos gastrintestinais e os maiores valores de volume globular. O pastejo rotacionado de ovinos, sem a utilização de bovinos, não foi eficiente no controle da verminose das ovelhas. A utilização do pastejo rotacionado e alternado de ovinos e bovinos adultos exerceu efeito benéfico significativo no controle da verminose ovina.The effects of rotational and alternate grazing involving cattle and sheep on the control of nematode parasites in sheep were evaluated. Three areas with 1.67ha were subdivided into eight paddocks each. Twenty ewes and four cattle were allotted to areas 1 and 2, respectively. They grazed during five days in each of eight paddocks of each area. The sheep and cattle rotated in each area for 40 days. At the end of this period, ewes were transferred to the area where cattle were previously kept and these animals were transferred to the area where sheep had previously grazed. This arrangement was kept until the end of the experiment. A control group with 20 ewes rotated in the third area, also with eight paddocks. Ewes that alternately grazed with cattle showed

    Full Text Available Background and purpose: Toxoplasmosis is a widespread zoonosis caused by Toxoplasma gondii. In addition to economic losses, this disease is transfer able to human and regarding the special ecological conditions of this parasite in nature of Mazandaran province, it is necessary to determine the situation of the disease. The purpose of this study was to determine the frequency of antibodies against T. gondii in cattle, sheep and goats slaughtered in official slaughterhouses in Mazandaran province, in 2004.Materials and Methods: To determine the prevalence of toxoplasmosis in slaughtered animals, in a descriptive cross-sectional study, 639 blood samples were obtained from cattle, sheep and goats between December 2004 and April 2005, from the three main geographical zones of Mazandaran province, Iran. Nine slaughterhouses were randomly selected in Western, Central and Eastern regions. Sera were extracted from 5mL venous blood samples, by centrifugation at 2000xg for 10 min, and were stored at –20º C prior to testing. Sera were screened for T. gondii antibodies by immunofluorescence antibody test (IFAT and serum samples showing a titre of 1:16 were further diluted to determine the end point. Data were analyzed using Chi-square (X2 test.Results: Of the 639 serum samples examined, 27.5% (176/639 showed positive titers equal or higher than 1:16 by IFAT. The highest frequency of antibody titres (1:16 titre were found in sheep and the least in cattle (9%. The highest infection rates in cattle were seen in western region with 5.5 % antibody titres of 1:16. In three regions, 35% of sheep sera showed positive titers with high frequency of 1:16 antibody titre (17.3% in Western region. Thirty percent of goat sera in 3 regions were seropositive and the highest infection rate was seen in 1:16 titre (18.5% in Western region.Conclusion: The results of this study show that the presence of T. gondii specific antibodies for sheep and goats in Northern Iran is high

    Full Text Available The success of Genome Wide Association Studies in the discovery of sequence variation linked to complex traits in humans has increased interest in high throughput SNP genotyping assays in livestock species. Primary goals are QTL detection and genomic selection. The purpose here was design of a 50-60,000 SNP chip for goats. The success of a moderate density SNP assay depends on reliable bioinformatic SNP detection procedures, the technological success rate of the SNP design, even spacing of SNPs on the genome and selection of Minor Allele Frequencies (MAF suitable to use in diverse breeds. Through the federation of three SNP discovery projects consolidated as the International Goat Genome Consortium, we have identified approximately twelve million high quality SNP variants in the goat genome stored in a database together with their biological and technical characteristics. These SNPs were identified within and between six breeds (meat, milk and mixed: Alpine, Boer, Creole, Katjang, Saanen and Savanna, comprising a total of 97 animals. Whole genome and Reduced Representation Library sequences were aligned on >10 kb scaffolds of the de novo goat genome assembly. The 60,000 selected SNPs, evenly spaced on the goat genome, were submitted for oligo manufacturing (Illumina, Inc and published in dbSNP along with flanking sequences and map position on goat assemblies (i.e. scaffolds and pseudo-chromosomes, sheep genome V2 and cattle UMD3.1 assembly. Ten breeds were then used to validate the SNP content and 52,295 loci could be successfully genotyped and used to generate a final cluster file. The combined strategy of using mainly whole genome Next Generation Sequencing and mapping on a contig genome assembly, complemented with Illumina design tools proved to be efficient in producing this GoatSNP50 chip. Advances in use of molecular markers are expected to accelerate goat genomic studies in coming years.

    Full Text Available Abstract Background Bovine tuberculosis (BTB is endemic in Ethiopian cattle. The aim of this study was to assess BTB prevalence at an intensive contact interface in Meskan Woreda (district in cattle, small ruminants and suspected TB-lymphadenitis (TBLN human patients. Methods The comparative intradermal test (CIDT was carried out for all animals involved in the cross-sectional study and results interpreted using a > 4 mm and a > 2 mm cut-off. One PPD positive goat was slaughtered and lymph nodes subjected to culture and molecular typing. In the same villages, people with lymphadenitis were subjected to clinical examination. Fine needle aspirates (FNA were taken from suspected TBLN and analyzed by smear microscopy and molecular typing. Results A total of 1214 cattle and 406 small ruminants were tested for BTB. In cattle, overall individual prevalence (> 2 mm cut-off was 6.8% (CI: 5.4-8.5% with 100% herd prevalence. Only three small ruminants (2 sheep and 1 goat were reactors. The overall individual prevalence in small ruminants (> 2 mm cut-off was 0.4% (CI: 0.03-5.1% with 25% herd prevalence. Cattle from owners with PPD positive small ruminants were all PPD negative. 83% of the owners kept their sheep and goats inside their house at night and 5% drank regularly goat milk. FNAs were taken from 33 TBLN suspected cases out of a total of 127 screened individuals with lymph node swellings. Based on cytology results, 12 were confirmed TBLN cases. Nine out of 33 cultures were AFB positive. Culture positive samples were subjected to molecular typing and they all yielded M. tuberculosis. M. tuberculosis was also isolated from the goat that was slaughtered. Conclusions This study highlighted a low BTB prevalence in sheep and goats despite intensive contact with cattle reactors. TBLN in humans was caused entirely by M. tuberculosis, the human pathogen. M. tuberculosis seems to circulate also in livestock but their role at the interface is unknown.

    To assess the effectiveness of the strategies implemented in the European Union (EU) to control Classical scrapie (CS), epidemiological data have been compared in the context of the efforts in terms of control measures applied over time. Official EU surveillance data and results from questionnaire...... trends and geographical distribution: among the 13 countries reporting a consistent number of cases, the trend analysis shows a statistically significant decreasing trend only for six of them. Variations in the implementation of genetic and non-genetic measures for the control of CS may explain the...... failure to improve the disease situation in the remaining seven MSs. At a national level, a reduction in CS seems to be linked to better-achieving BP-CSs. Control options applied to CS in sheep and goats indicate that a CS eradication policy that relies solely on the detection of infected flocks by post...

    The present study was undertaken to identify polymorphism in the coding sequence of GDF8gene across indigenous meat type sheep breeds. A 1647 bp sequence was generated, encompassing 208 bp of the 5'UTR, 1128 bp of coding region (exon1, 2 and 3) as well as 311 bp of 3'UTR. The sheep and goat GDF8 gene sequences were observed to be highly conserved as compared to cattle, buffalo, horse and pig. Several nucleotide variations were observed across coding sequence of GDF8 gene in Indian sheep. Three polymorphic sites were identified in the 5'UTR, one in exon 1 and one in the exon 2 regions. Both SNPs in the exonic region were found to be non-synonymous. The mutations c.539T > G and c.821T > A discovered in this study in the exon 1 and exon 2, respectively, have not been previously reported. The information generated provides preliminary indication of the functional diversity present in Indian sheep at the coding region of GDF8gene. The novel as well as the previously reported SNPs discovered in the Indian sheep warrant further analysis to see whether they affect the phenotype. Future studies will need to establish the affect of reported SNPs in the expression of the GDF8 gene in Indian sheep population. PMID:26845859

This drug is used for treatment infection in respiratory, urinary, reproductive, forelimb and hind limb systems in cattle, goats, sheep and rabbits. Hipracilina is intramuscularly injected at dose 1 mL/10 kg body weight once or twice in day for 3 days. Hipracilina was clinically used at dose 1.5 mL/B.W in kid goats. The kids had 6 days age and 3kg weight. These animals had diarrhea after high milk eating. One kids died after 15 min. Fourteen kids had signs such as ataxia, depression, hind limb paralysis, hyperesthesia, mydriasis, decreasing of respiratory rate, tachycardia and falling. Two kids died after 4 h. Supportive treatment was carried by ORS powder and furosemide administration. The kids returned to normal state after 24 h. In another experimental study we divided kids 3 groups which received A: benzyl penicillin, B: benzyl penicillin+dihydrostreptomycin, and C: chlorpheniramine. Group A and B showed depression. Thus, Hipracilina can be toxic in kid goats at nearly 4-5 folds dose. It seems that this toxicity is related to penicillin compound.

The importance of T. gondii in Norwegian goat herds is uncertain, but outbreaks of toxoplasmosis in dairy goat farms have been recorded. The aim of this study was to describe the prevalence of T. gondii infection in Norwegian dairy goats by using serology. Findings Goat serum originally collected as part of two nationwide surveillance and control programmes between 2002 and 2...

    Full Text Available The ongoing global spread of "exotic" farm animals, such as water buffaloes, which carry their native sets of viruses, may bear unknown risks for the animals, into whose ecological niches the former are introduced and vice versa. Here, we report on the occurrence of malignant catarrhal fever (MCF on Swiss farms, where "exotic" water buffaloes were kept together with "native" animals, i.e. cattle, sheep, and goats. In the first farm with 56 water buffaloes, eight cases of MCF due to ovine herpesvirus-2 (OvHV-2 were noted, whereas additional ten water buffaloes were subclinically infected with either OvHV-2 or caprine herpesvirus-2 (CpHV-2. On the second farm, 13 water buffaloes were infected with CpHV-2 and two of those succumbed to MCF. In neither farm, any of the two viruses were detected in cattle, but the Macaviruses were present at high prevalence among their original host species, sheep and goats, respectively. On the third farm, sheep were kept well separated from water buffaloes and OvHV-2 was not transmitted to the buffaloes, despite of high prevalence of the virus among the sheep. Macavirus DNA was frequently detected in the nasal secretions of virus-positive animals and in one instance OvHV-2 was transmitted vertically to an unborn water buffalo calf. Thus, water buffaloes seem to be more susceptible than cattle to infection with either Macavirus; however, MCF did not develop as frequently. Therefore, water buffaloes seem to represent an interesting intermediate-type host for Macaviruses. Consequently, water buffaloes in their native, tropic environments may be vulnerable and endangered to viruses that originate from seemingly healthy, imported sheep and goats.

    Protease preparations from plant (papain and bromelain) and fungal (FP400 and FPII) sources were used to hydrolyze the red blood cell fractions (RBCFs) separated from deer, sheep, pig, and cattle abattoir-sourced blood. After 1, 2, 4 and 24h of hydrolysis, the antioxidant and antibacterial activities of the peptide hydrolysates obtained were investigated. The increase in trichloroacetic acid-soluble peptides over the hydrolysis period was examined using the o-phthaldialdehyde (OPA) assay and the hydrolysis profiles were illustrated using SDS-PAGE. Papain generated RBCF hydrolysates exhibited higher ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC) compared to those generated with bromelain, FP400 and FPII. At certain concentrations, 24h hydrolysates of RBCF using FP400 and FPII were able to inhibit the growth of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The results indicated that the use of proteases from plant or fungal sources can produce animal blood hydrolysates with antioxidant and antimicrobial activities. PMID:26920319

    Testicular cell proliferation and differentiation is critical for development of normal testicular function and male reproductive maturity. The objective of the current study was to evaluate histoarchitecture and expression of genes marking specific cells and important functions as well as testosterone production of the developing goat testes. Testes were harvested from Alpine bucks at 0, 2, 4, 6, and 8 mo of age (n = 5/age group). Paired testes weight increased from 2 to 4 (P Growth Factor 1 Receptor (IGF1R), and Heat Shock Protein A8 (HSPA8). The Glutathione S-Transferase A3 (GSTA3) gene, whose product was recently recognized as a primary enzyme involved in isomerization of androstenedione in man and livestock species including goats, sheep, cattle, pigs, and horses, uniquely peaked in expression at 2 mo (P Hormone Receptor (FSHR) mRNA abundance tended to steadily decrease with age (P = 0.1), while Luteinizing Hormone Receptor (LHCGR) mRNA abundance in testes was not significantly different across the ages. Testosterone content per gram of testicular tissue varied among individuals. However, testosterone content per testis tended to increase at 6 mo (P = 0.06). In conclusion, major changes in cellular structure and gene expression in goat testes were observed at 4 mo of age, when spermatogenesis was initiated. Male goats mature rapidly and represent a good model species for the study of agents that enhance or impair development of testicular functions. PMID:25085396

  19. The Application of Genomic Technologies to Investigate the Inheritance of Economically Important Traits in Goats

    2014-01-01

    Full Text Available Goat genomics has evolved at a low pace because of a lack of molecular tools and sufficient investment. Whilst thousands and hundreds of quantitative trait loci (QTL have been identified in cattle and sheep, respectively, about nine genome scans have been performed in goats dealing with traits as conformation, growth, fiber quality, resistance to nematodes, and milk yield and composition. In contrast, a great effort has been devoted to the characterization of candidate genes and their association with milk, meat, and reproduction phenotypes. In this regard, causal mutations have been identified in the αS1-casein gene that has a strong effect on milk composition and the PIS locus that is linked to intersexuality and polledness. In recent times, the development of massive parallel sequencing technologies has allowed to build a reference genome for goats as well as to monitor the expression of mRNAs and microRNAs in a broad array of tissues and experimental conditions. Besides, the recent design of a 52K SNP chip is expected to have a broad impact in the analysis of the genetic architecture of traits of economic interest as well as in the study of the population structure of goats at a worldwide scale.

    Bovine viral diarrhea virus (BVDV) is a pestivirus best known for causing a variety of disease syndromes in cattle, including gastrointestinal disease, reproductive insufficiency, immunosuppression, mucosal disease, and hemorrhagic syndrome. The virus can be spread by transiently infected individuals and by persistently infected animals that may be asymptomatic while shedding large amounts of virus throughout their lifetime. BVDV has been reported in over 40 domestic and free-ranging species, and persistent infection has been described in eight of those species: white-tailed deer, mule deer, eland, mousedeer, mountain goats, alpacas, sheep, and domestic swine. This paper reviews the various aspects of BVDV transmission, disease syndromes, diagnosis, control, and prevention, as well as examines BVDV infection in domestic and wild small ruminants and camelids including mountain goats (Oreamnos americanus).

Carlteton Gajdusek found a new virus without the characteristic of DNA and RNA, which was awarded the Nobel Prize in physiology in 1976. Since then another American sci-entist, Stanley B. Prusiner, found a new virus-prion, taking protein as the genetic medium, which was awar-ded the Nobel prize in physiology and medicine in 1997. The discovery of prion is a great landmark in the re-search of life science, which laid a theoretical foundation for people to conquer n series of diseases such as Scrapie syndrome in sheep and goats, Creutzfeldt-Jakob disease, kuru disease and mad cow disease etc.

Presentamos el caso de un varón con clínica de disfagia intermitente coincidiendo con la toma de quesos curados de oveja y cabra que precisó asistencia urgente tras la impactación de un comprimido de ibuprofeno a 30 cm de la arcada dentaria. El estudio practicado demostró la existencia de estenosis en el esófago a ese nivel con infiltración eosinofílica difusa y sensibilización a proteínas de la leche de cabra, oveja y vaca, con especial relevancia para la IgG bovina, lactoferrina y albúmina sérica. Tras tratamiento con fluticasona deglutida y medidas de evitación se consiguió la resolución del cuadro clínico y la desaparición de los eosinófilos en la mucosa.Eosinophilic esophagitis is an inflammatory disease of the esophagus characterized by the presence of high numbers of eosinophils in the esophageal mucosal layer (> 20 high-power field. It is uncommon in adults but in such cases intermittent dysphagia and food impaction are the most common presenting symptoms. We report the case of a male with long-standing intermittent dysphagia after eating selected goat and sheep cheese types, who required medical help following the impaction of an ibuprofen pill in the esophagus. A biopsy demonstrated the presence of eosinophilic inflammation, and allergy testing showed specific IgE against proteins in the milk of goats and sheep. Topical steroid therapy with oral fluticasone, and the elimination of these dairy products from the diet induced complete symptom resolution, and biopsy specimens taken 4 months later showed no eosinophils.

  5. Transfer of 131I to sheep milk from vegetation contaminated by Chernobyl fallout

    International Nuclear Information System (INIS)

    The transfer of 131I to sheep milk was measured in a controlled feeding experiment using herbage recently contaminated by fallout from the Chernobyl accident. The transfer coefficient (Fm) of 131I from the Chernobyl-contaminated herbage was 0.29±0.017 day litre-1. The daily proportion of 131I intake which was secreted in milk was 56±0.035%. This is an order of magnitude higher than for cattle and agrees with the higher transfer of stable iodine from plasma to milk which occurs in sheep and goats. At the same time the biological half-life of 131I was measured in ewes which had been grazing outside during deposition of the Chernobyl fallout and were then housed and fed an 131I-free diet. The loss of 131I in sheep milk was described using a double exponential relationship. The calculated biological half-life for the first component in the milk was 1 day, accounting for 97.4% of the reduction in the concentration of 131I activity in the milk. The 131I-free diet had a comparatively high stable iodine content since it was saltmarsh vegetation, however, the calculated half-life was similar to previously estimated values for goats. (Author)

  8. Significance of Neospora caninum in cattle farming

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Neospora caninum is an obligate intracellular protozoan parasite which primarily causes diseases in dogs and cattle all over the world. It was first described in Norway in the mid-eighties in dogs, after which, until the present time, clinical neosporosis was proven in sheep, goats, deer, rhinoceroses, horses, and experimental rodents. Antibodies against N. caninum have been found also in the serum of water buffalo, red and gray foxes, coyotes, camels, and felines. Due to the similarity of this Coccidia with Toxoplasma gondi, the neosporosis was for a series of years incorrectly diagnozed as toxoplasmosis. Domestic canines, dogs, are the only real host for N. caninum. Its life cycle covers three stages of development: tachyzoites, tissue cysts and oocysts. Carnivores are infected by ingesting parts of infected tissue which contain tissue cysts with bradyzoites. The dominant pathway of transmission of this cause in cattle is transplacentary infection, but cattle can also be infected by ingestion of feed or water contaminated by sporulated oo-cysts of N. caninum. Bitches can be subclinical carriers of the parasite, when they pass on the cause transplacentarily, which results in more than one litter being born with the infection. Neosporosis today appears as the main cause of abortions and neonatal deaths in dairy cows and fattening cattle in almost all parts of the world, but with the highest incidence in the United States (US, New Zealand, The Netherlands, and Germany. The treatment of this disease has not been fully determined, but medicines used for the treatment of toxoplasmosis have yielded certain good results. There is no verified vaccine that would prevent undesired abortions in cattle. .

    Between 2007 and 2009, the largest human Q fever epidemic ever described occurred in the Netherlands. The source was traced back to dairy goat farms, where abortion storms had been observed since 2005. Since one putative cause of these abortion storms is the intensive husbandry systems in which the goats are kept, the objective of this study was to assess whether these could be explained by herd size, reproductive pattern and other demographic aspects of Dutch dairy goat herds alone. We adapted an existing, fully parameterized simulation model for Q fever transmission in French dairy cattle herds to represent the demographics typical for Dutch dairy goat herds. The original model represents the infection dynamics in a herd of 50 dairy cows after introduction of a single infected animal; the adapted model has 770 dairy goats. For a full comparison, herds of 770 cows and 50 goats were also modeled. The effects of herd size and goat versus cattle demographics on the probability of and time to extinction of the infection, environmental bacterial load and abortion rate were studied by simulation. The abortion storms could not be fully explained by demographics alone. Adequate data were lacking at the moment to attribute the difference to characteristics of the pathogen, host, within-herd environment, or a combination thereof. The probability of extinction was higher in goat herds than in cattle herds of the same size. The environmental contamination was highest within cattle herds, which may be taken into account when enlarging cattle farming systems. PMID:23621908

    Understanding the factors governing host species barriers to virus transmission has added significantly to our appreciation of virus pathogenesis. Jaagsiekte sheep retrovirus (JSRV) is the causative agent of ovine pulmonary adenocarcinoma (OPA), a transmissible lung cancer of sheep that has rarely been found in goats. In this study, in order to further clarify the pathogenesis of OPA, we investigated whether goats are resistant to JSRV replication and carcinogenesis. We found that JSRV induce...

    .The objective of this study was to determine the fluctuation of serum antibodies in goats in the period before and immediately after kidding and the passive immunity acquisition efficiency in kids fed bovine and goat colostrum, to assess an alternative for colostrum management. Eighteen goats and their offspring were used in a total of 33 animals. Goat blood samples started to be collected 45 days before the predicated kidding date, at five-day intervals until the 5th day post kidding. The kids were distributed in two groups: one group received goat colostrum and the other cattle colostrums. Blood collections were made 0, 12, 24 and 48 hours, and at 5, 10, 15, 17, 20, 25, 30, 40, 50 and 60 days of age. The serum concentration of total protein (TP and immunoglobulins (Ig, and the colostrum IgG concentration were analyzed. A randomized complete design was used and the serum variables were analyzed as repeated measurements. The absence of fall in TP and Ig serum concentration in the pre partum period, indicated that the mobilization of serum antibodies to mammary gland occurred in concentrations that allow the animals to keep these variables without great alterations. In the group that received cattle colostrum, the highest concentration data for TP was observed at 48.68 ± 0.79 hours after birth, with mean of 7.16 ± 0.28 g/dL, and the highest concentration date for Ig at 48 ± 0.73, with mean of 37.56 ± 2.38 ZST units (zinc sulfate turbidity. In the group that received goat colostrum, the maximum values for serum TP and Ig occurred later, at 20.05 ± 1.36 and 20.11 ± 1.72 days after birth, with means of 5.91 ± 0.22 g/dL and 28.17 ± 2.05 ZST units (zinc sulphate turbidity, respectively. Goat colostrum can be substituted by cattle colostrums, that promotes better initial immunoglobulin acquisition by the neonates.

    Sarcoptic mange infested sheep showed pruritis, excoriation, crusts, lichenification and secondary alopecia on face and ears. All the infested sheep were treated successfully with Ivermectin at 200 μg/kg body weight and complete recovery of skin was observed between 10th and 14th day post treatments. Sarcoptic mange is highly contagious and the spread of Sarcoptes scabiei is usually by close contact but in goats not same because it has natural resistance against sheep mange. PMID:24431584

    The insulin-like growth factor 1 has an important role in reproduction, foetal development and growth. It regulates the secretion of gonadotrophin releasing hormone, stimulates ovarian function and steroidogenesis. The present study was conducted to characterise the 5' flanking region of goat IGF 1 gene, ascertain ovarian expression of the IGF1 gene, detect SNPs and assess the association with prolificacy in the two indigenous goat breeds of South India viz., low prolific Attappady Black and high prolific Malabari. The 5' flanking region of IGF1 gene was PCR amplified, cloned and sequenced from both breeds. Genotyping was performed in 277 goats from the two genetic groups using the PCR-Single Strand Conformational Polymorphism (SSCP) and the expression of the IGF1 gene in the ovary was analysed by quantitative real time PCR. The 5' flanking region of the IGF1 gene was 601 bp long and located at 450 bp upstream of the start codon. Sequence exhibited 97-99% similarity with that of the sheep, cattle and sika deer IGF1 genes. Three genotypes, PP, PQ and QR were observed at this locus with the frequency of 0.62, 0.30 and 0.08, respectively. Sequencing of the representative PCR products from each genotype revealed two SNPs, g.224A>G and g.227C>T. The population was found to be in Hardy-Weinberg disequilibrium at both loci. Statistical results indicated that these loci were associated with litter size (P ≤ 0.05). However, no significant difference was found in the expression of the IGF1 gene in the ovaries of the two goat breeds. These results suggest the significant influence of the IGF1 gene on prolificacy in goats and identified SNPs would benefit the selection of prolific animals in future breeding programs.

    Full Text Available The determination of the degree of differentiation of animal populations at breed level is an important issue for conservation purposes. Morphometric divergences can be an indicator of adaptative or selective differences between breeds. In fact, due to the natural and artificial selection that continuously acts on the adaptative traits, the determination of the level of divergence of the quantitative traits across several populations, allows to make inferences on the degree of adaptation to a certain environment or on the productive specialization of a given population. Somatic measures have already been used to estimate the divergence in Italian cattle (Camussi et al., 1985, goat (Cicogna et al., 1995, Herrera et al. 1996 and sheep breeds (Panella et al., 1993...

  9. Genetic diversity and differentiation of Mongolian indigenous cattle populations

    International Nuclear Information System (INIS)

    Livestock production plays an important role in Mongolian economy. Over the last decade it has contributed to around 80-90% of the gross domestic agricultural products and to 30% of the revenues generated from exportations. Cattle is one of the five traditional and most important livestock species of Mongolia together with horse, sheep, goat and camel. Out of a total of 1.57 millions Mongolian cattle, 1.55 millions supposedly belong to three indigenous Bos taurus cattle breeds, namely Mongol, Selenge and Khalkhun Golun, all herded under extensive pastoral systems. Indigenous Mongolian cattle are generally small but look sturdy and strong. They have a well-off coat of hair, solid forward looking shoulders and short stubby snouts, and they are used for meat, milk and transport. Beef production contributes to 30% of the total meat supply in Mongolia. The Mongol breed is by the far the commonest with 1.53 million animals and it is found almost throughout the country. The Selenge breed, found in Selenge province and numbering 9000 heads, was developed in middle of the 20th century by crossing the Kazakh Whiteheaded with the local Mongol cattle. The Khalkhun Golun breed was developed from local Mongol cattle and it is distributed in Eastern and Suhbaatar provinces with about 10,000 heads. Until now, to the best of our knowledge, only a single population of Mongolian cattle has been studied with microsatellite DNA markers and no information is available on the genetic relationship between the Mongolian indigenous cattle breeds. In this study, we collected samples from two populations of the Mongol cattle (sampled at Ikhtamir soum in North Hangay province and Tsogt soum in Govi Altay province) and one population of the Khalkhun Golun cattle (sampled at Tumentsogt soum in Suhbaatar province). Samples were characterised with nine microsatellite markers MGTG4B, ILSTS005, ILSTS006, ILSTS008, ILSTS023, ILSTS028, ILSTS036, ILSTS050 and ILSTS103. To assess the genetic diversity

    Bluetongue (BT) is a viral disease that is spread mainly by one specific type of gnat. Other gnats and blood sucking insects may occasionally transmit BT, but they are much less important in its transfer. Cattle are the main reservoir for overwintering of the virus in temperate climates. The gnats become infected from cattle and then spread the disease to other cattle and sheep as they take blood meals.

    为探讨羊经布鲁氏菌病疫苗免疫后的血清抗体消长规律,本研究分别对绵羊和山羊进行布鲁氏菌S2株疫苗不同剂量的灌服,于免疫前和免疫后不同时间采集血清样品,采用虎红平板凝集试验和试管凝集试验进行血清抗体检测。结果表明,绵羊及山羊均在免疫后20d时血清抗体阳性率达到最高峰,之后呈下降趋势,免疫后90天降至低点。免疫后90至360d,绵羊组抗体阳性率几乎一直维持在14%以下,各时段无显著性差异(P>0.05);山羊组抗体阳性率在免疫后90至360d期间时高时低,起伏较大,无明显规律。试验期间,山羊的抗体阳性率普遍高于绵羊,且降升幅度较大。同时,研究表明,同种羊100亿和200亿两个免疫剂量组的抗体阳性率差异不大。%To investigate the pattern of increasing or decreasing of serum antibody in sheep and goats immunized with brucellosis vaccine,RPST and tube agglutination test were used in the study to determine the level of serum antibody in sheep and goats before and after immunization with Brucella strain S2 vaccine. The results indicated that the serum antibody positive rate in sheep reached the highest level 20 DPI,then started to decrease and remained relatively low level 90-360 DPI,mostly below 6%,and relatively higher in few individuals,up to 14%. The positive rate in goats reached the highest 20 DPI,then decreased and remained low or relatively low level 90-360 DPI,but with decreasing or increasing sometimes. Comparatively,antibody positive rate in goats was generally higher than in sheep,and the descending and ascending range was bigger. It was also shown that there was no significant difference in antibody posi-tive rate between 10 billion CFU dose group and 20 billion CFU dose group in same species.

    Full Text Available Small ruminant production is the main source of income of farmers living in arid and semiarid regions. Sheep and goats raised in these areas are generally confronted with severe nutritional deficits during food scarcity period which exacerbate disease and health problems and consequently low productive and reproductive performances. These areas are characterized by rainfall seasonality and scarcity resulting in a low fodder potential. Therefore, native rangelands are degrading due to overgrazing, high stocking rates and mismanagement. Options to improve small ruminant-based production systems include i innovative technologies targeting the increase of feed resources availability, rumen manipulation using natural compounds to boost microbial activity, improving diets' quality, alleviation of feeding cost, and better control of livestock watering. Although this paper is focussing on the benefits from these technical options, we should bear in mind that i the organization of local institutions for better adoption of these technologies and for protecting the main natural resources (rangelands and water and ii the participatory approach involving all partners concerned with the improvement of farmer's income and livelihood are key tools for promoting livestock sector in the target areas. A set of simple, inexpensive and environmentally friendly options that could ameliorate small ruminant production in the semiarid regions are discussed in this paper.A produção de pequenos ruminantes é a principal fonte de renda dos agricultores que vivem em regiões áridas e semiáridas. Ovinos e caprinos criados nessas áreas geralmente enfrentam severas deficiências nutricionais durante o período de escassez de alimentos, que comprometem a sua saúde e, conseqüentemente, resultam em baixo desempenho produtivo e reprodutivo. Estas áreas são caracterizadas pela sazonalidade e escassez das chuvas, que resultam em baixo potencial forrageiro. Além disso, as

    goats. Four sheep and four cashmere goats aged 1.5 years, weighted 45 kg and fitted with permanent ruminal cannulas were selected as experimental animals. Own control experimental design was used, and the study was conducted in consecu-tive four periods. Animals in the four periods were fed a basal diet ( period 1, group Ⅰ) , and the basal diet supplemented with 2% tannin ( period 2, group Ⅱ) , 6% tannin ( period 3, group Ⅲ) and 6% tannin + 12%PEG ( period 4, group Ⅳ) , respectively. Each period lasted for 30 days consisted of a 12-day pre-test period and 18-day test period. On the 1st day of each test period, ruminal content was collected, rumen fluid pH, and the concentrations of ammonia nitrogen ( NH3-N) and microbial protein ( MCP) were measured, and real-time PCR was used to quantify R. albus, R. flavefaciens and F. succinogenes adherent to solid phase, liquid phase and full chyme. The results showed that as follows: 1) compared with group Ⅰ, the supplementation of 6%tannin significantly decreased NH3-N concentration in rumen fluid in goats and MCP concentration in rumen fluid of sheep ( P<0.05) . These two indices recovered to the same level with group Ⅰ after the supplementa-tion of 6% tannin+12% PEG. 2) Compared with groupⅠ, the supplementation of 6% tannin significantly de-creased the quantity of R. albus in solid phase of ruminal content in sheep and goats, and in liquid phase of ru-minal content in sheep ( P<0.05);the supplementation of 2% and 6% tannin significantly decreased the quan-tity of R. flavefaciens in solid phase of ruminal content in sheep and goats ( P<0.05) , and the supplementation of 6% tannin significantly decreased the quantity of R. flavefaciens in liquid phase of ruminal content in sheep and goats ( P<0.05);the supplementation of 6% tannin significantly decreased the quantity of F. succinogenes in solid phase of ruminal content of sheep and goats, and in full chyme of ruminal content in sheep ( P<0.05) .

    Small ruminants, like goats, would make excellent animal models for not only infectious diseases in large ruminants but also analogous diseases in humans, such as human tuberculosis, Crohnâs disease, melioidosis and brucellosis. The main disadvantage for the small ruminant model is the lack of sufficient baseline data on normal, healthy goat kids. Furthermore, most reagents (antibodies and the like) were not developed for goats or sheep. It is important to demonstrate that available resources...

  4. Effects of urea-molasses multi-nutrient block (UMMB) on cattle/yak production and medicated UMMB (MUMB) on control of parasites in sheep in Gansu Province, China

    International Nuclear Information System (INIS)

    Urea-molasses multi-nutrient blocks (UMMB) were prepared and evaluation trials conducted in Gansu Province, China. Supplementation with UMMB had a positive effect on animal performance. In Jiuquan, cross-bred beef cattle (local X Simmental) aged 1.5 years were offered UMMB during a 45 day fattening period. After the fattening period, each animal was worth an extra 80.8 Yuan of net profit from the additional weight gain and the cost/benefit ratio was increased by more than four times. A production increase of smaller magnitude was evident in a trial in Linxia with chauri (cattle X yak), aged from 8 to 12 years, and the cost/benefit ratio was 1 : 2.3. Another trial was conducted in dairy cows (cross-bred local X Friesian Holstein) in Yunchang, in 2000, where UMMB supplementation resulted in a significant increase in milk production with a cost/benefit ratio of 1 : 5.6. Detailed studies on rumen NH3-N levels were conducted in cannulated yak before and after eating UMMB and the dynamic concentration of NH3-N level increased by two to five times when UMMB was available. A trial with UMMB containing herbal anthelmintic medication was carried out in sheep in Linxia and Yunchang and it was shown that this treatment was as effective as the conventional treatment with albendazole. Economic evaluation of this treatment showed that the cost of medicinal herbs was four times that of chemical anthelmintics to control parasites and, hence, this method is not likely to be adopted by smallholder farmers in this area of China.

  7. Reproductive wastage through slaughtering of pregnant ewe and goat in Quagadougou, Burkina Faso

    International Nuclear Information System (INIS)

    Data collected from 3190 small ruminants (2408 ewe and 782 goats) have been examined after slaughtering, from January to June 2005 in Ouagadougou refrigerated abattoir. 26.70% of sheep and 34.91% of goats were more in advanced gravidity with losses estimated to 0.33 lamb and 0.44 kid per slaughtered sheep and goat. Animals slaughtered during the second half of their gravidity (2-5 months) represented 53.19% of sheep and 58.24% of goats although at this period, the foetus becomes palpable and detectable. This survey attracts the attention on the losses due to the slaughtering of pregnant females, as the deficit in animal proteins doesn't stop worsening. Urgent measures must be considered to decrease the extent of these losses and it is recommended to detect pregnancy females in abattoir and breeders must be trained to simple methods of gestation detection

    Sarcocystis is one of the most prevalent protozoan parasites in the striated muscles of livestock slaughtered for food such as cattle, sheep and goat. Meat that is heavily infected may be condemned as unfit for human consumption. The aim of this study was to determine the prevalence of Sarcocystis spp. in slaughtered cattle in Tabriz, northwest of Iran. The prevalence of Sarcocystis spp. infection was investigated in 670 cattle, slaughtered from April 2013 to October 2013 in the Tabriz abattoir, Iran using naked eye examination for macroscopic Sarcocysts, and peptic digestion, muscle squash, squeezing methods for microscopic types. Muscles from oesophagus, tongue, heart, diaphragm and cervical and abdominal of 670 slaughtered cattle were examined for Sarcocystis spp. cysts. The prevalence of microscopic Sarcocystis spp. cysts in cattle was detected in 100 % and there was detected in macroscopic cyst 8.2 % in examined cattle. There were no significant differences among the infection rates of the different organs (P > 0.05). There were no significant differences among the infection rates of the different ages (P > 0.05). The prevalence of macroscopic infection in the oesophagus was higher than that of the other organs (P sex (8.25 % in males and 8.13 % in females, P > 0.05). This suggests that meat should be cooked sufficiently, since a macroscopic inspection may not provide true results. Also, it has of great importance the farmers to be trained not to feed their dogs and cats with uncooked meat, and the abattoir remnants to be burned, in order to be effectively broken of infection cycle between the intermediate and the definitive hosts in Tabriz city, northwest of Iran.

  10. Forage particle breakdown and movement in the reticulo-rumen in cattle and interactions between cold exposure and diets in sheep

    International Nuclear Information System (INIS)

    Sheep, fitted with cannulas in the rumen and proximal duodenum, were given different diets as well as different physical forms of diets. The sheep were closely shorn and exposed to ambient temperatures of 22 deg. C to 24 deg. C (warm) or 1 deg. C to 5 deg. C (cold). Measurements of rates of passage, digestibility, rate of transfer of plasma urea to the rumen, feed protein degradation, microbial protein synthesis and rate of rumen fermentation were determined. The effect of cold exposure on digestion was not dependent on the physical form of the diet given at a fixed intake, but was associated with the type of diet (hay, concentrate). The greater voluntary intake was a result of increased clearance of digesta from the rumen through decreased particle size and increased frequency of reticulum contractions. The apparent digestibility of organic matter and nitrogen was reduced for hay diets in cold exposure, which increased the escape of dietary N from the abomasum and the efficiency of microbial synthesis. Cold exposure did not affect urea transfer from plasma to the rumen. Subsequently, two steers fitted with cannulas in the oesophagus and rumen were used in a 2x2 cross-over design to study the physical breakdown of different diets. Concomitantly, four steers, each fitted with a rumen cannula, were used in a 4x4 Latin square design to investigate removal of digesta components from the rumen. A combination of wet sieving and marker techniques for fluid, particulate and microbial movements was utilized. The fractional outflow rate (FOR) of 51Cr-EDTA in centrifuged rumen fluid was increased (P103Ru-P in mixed rumen digesta and organic 35S in microorganisms were linearly correlated (P0.05) by grinding and salt treatments

    Products of animal origin represent the main route of human exposure to dioxins and dioxin-like PCBs (DL-compounds). Recently, concerns have been raised about ovine products, particularly the liver, in which relatively high levels of DL-compounds have been reported. We surveyed ovine and bovine livers in areas with no known sources of dioxin or DL-PCB contamination, in order to assess accumulation patterns for both DL-compounds and non-DL (NDL-) PCBs. None of the ovine and bovine samples exceeded the current Maximum Limits (MLs) for DL-compounds. Liver DL-compound TEQ concentrations were up to 5-fold higher in sheep than in cows. No statistically significant differences in total NDL-PCBs levels were found. The main contributors to TEQ levels were the Penta- and Hexa-chlorinated PCDFs and PCB 126. The results confirm the increased bioaccumulation in ovine liver towards specific DL-compounds even in ewes reared in areas with no known sources of PCDD/Fs or DL-PCBs contamination. PMID:26963240

    Focal symmetrical encephalomalacia (FSE) is the most prominent lesion seen in the chronic form of enterotoxemia caused by Clostridium perfringens type D in sheep. However, this lesion has not been reported in goats. The current paper reports a case of FSE in a goat from the state of Paraíba in the Brazilian semiarid region. As reported by the farmer, 30, 4-48-month-old animals from a flock of 150 goats died after showing nervous signs, including blindness and recumbence, for periods varying between 1 and 14 days. The flock was grazing native pasture supplemented with wheat and corn bran. Additionally, lactating goats were supplemented with soybeans. A 4-month-old goat with nervous signs was examined clinically and then necropsied 3 days after the onset of clinical signs. Bilateral, focal, and symmetrical areas of brown discoloration were observed in the internal capsule and thalamus. Histologic lesions in these areas consisted of multifocal, bilateral malacia with a few neutrophils; endothelial cell swelling; perivascular edema; and hemorrhages. The etiology of these lesions was not determined. However, FSE is considered pathognomonic for C. perfringens type D enterotoxemia in sheep, and it is speculated that this microorganism was the etiologic agent in the present case. The flock had been vaccinated against type D enterotoxemia only once, approximately 3 months before the beginning of the outbreak. Insufficient immunity due to the incorrect vaccination protocol, low efficacy of the vaccine used, and a diet including large amounts of highly fermentable carbohydrates were suspected to be predisposing factors for this outbreak.

    Full Text Available Coat colour genes are useful candidates for breeds traceability of farm animals. To identify SNPs in genes involved in pigmentation in goat, we carried out in silico studies in human, mouse and cattle.We analysed 41 genes and we found: 88 SNPs in mouse, 29 synonymous and 59 non synonymous; 279 SNPs in humans, 121 synonymous and 158 non synonymous, 78 of which validated; 147 putative SNPs in cattle, 62 synonymous and 75 non synonymous, 10 of which validated. To identify the more interesting coding regions, we collected in these species information on pigmentation traits or on pathologies associated to different mutation. In goat, molecular information were available only on 7 genes and no SNP is reported, moreover poor information exists on association between mutations and different coat colour. Starting from the information collected in mouse, human and cattle, we obtained PCR products in goat for 61 exons in 36 genes. The PCR products were sequenced and checked for homology with the target sequences. Sequences on 8 animals from 4 breeds (Alpine, Saanen, Blonde of Adamello, Orobica characterised by different coat colour phenotypes have been compared, revealing 25 SNPs (11 synonymous, 14 non synonymous in 21 genes.

    The blood feeding nematode Haemonchus contortus infects the abomasum of small ruminants and compartment three (C-3) of camelids. Heavy infections may cause severe anemia and death. Alpacas were first introduced into the U.S. in the 1980s. Although not true ruminants, alpacas may become infected with H. contortus and develop the same clinical signs as sheep and goats. Even though alpacas may become infected with the parasite, prior research by Hill et al. (1993) and Green et al. (1996) indicat...

    Chronic fasciolosis is often diagnosed by faecal egg counting (FEC), following concentration of the eggs in the sample by a zinc sulphate floatation method. However, concentration by a sedimentation technique gives improved sensitivity. Interpretation of FEC results for fasciolosis is complicated by factors such as the long pre-patent period and irregular egg shedding. Thus, FEC reduction tests (FECRT), when used alone, are not completely reliable for diagnosis of anthelmintic susceptibility or resistance in local fluke populations, especially when parasite burdens are small. A Fasciola hepatica coproantigen ELISA test has been introduced which more accurately reflects the presence of flukes in the host bile ducts in late pre-patent infections, and absence of flukes following successful chemotherapeutic intervention. The aim of the present study was to elucidate the specificity of the F. hepatica coproantigen ELISA technique, particularly regarding potential cross-reactivity with rumen fluke (paramphistome), gastrointestinal nematode and coccidian infections. The method involved parallel testing of a large battery of faecal samples from field-infected cattle and sheep using floatation and sedimentation FECs and coproantigen analysis. No evidence was found for significant false positivity in the F. hepatica coproantigen ELISA due to paramphistome, coccidian and/or gastrointestinal nematode co-infections. With sedimentation FECs less than 10 F. hepatica eggs per gram (epg), the likelihood of a positive coproantigen result for the sample progressively decreased. Diagnosis of fasciolosis should be based on consideration of both FEC and coproantigen ELISA findings, to ensure optimum sensitivity for pre-patent and low-level infections. PMID:26234898

    Cloning by somatic cell nuclear transfer (SCNT) is characterized by low efficiency and the occurrence of developmental abnormalities, which are rather poorly studied phenomena in goats. This study aimed at comparing overall SCNT efficiency in goats by using in vitro-matured (IVM) or in vivo-matured oocytes and fibroblast donor cells (mock transfected, transgenic, or wild type), also characterizing symptoms of the Abnormal Offspring Syndrome (AOS) in development, comparing results with pregnancies produced by artificial insemination (AI) and in vivo-derived (IVD) embryos. The SCNT group had lower pregnancy rate (18.3%, 11/60), total number of concepti (20.0%, 12/60), term births (3.3%, 2/60), and live births (1.7%, 1/60) than both the IVD (77.8%, 7/9; 155.5%, 14/9; 122.2%, 11/9; 88.8%, 8/9) and the AI (71.4%, 10/14; 121.4%, 17/14; 100%, 14/14; 78.5%, 11/14) groups, respectively (p < 0.05). No SCNT pregnancies reached term using IVM oocytes, but in vivo-matured oocytes resulted in two term transgenic cloned kids. The proportion fetal membrane (FM) weight/birth weight reflected an increase in FM size and cotyledonary enlargement in clones, for disproportionally bigger newborns in relation to cotyledonary numbers. Overall, goat cloning showed losses and abnormality patterns similar to the AOS in cloned cattle and sheep, which have not been previously well recognized in goats. PMID:27362734

    Full Text Available Abstract In order to simultaneously integrate linkage and syntenic groups to the ovine chromosomal map, a sheep bacterial artificial chromosome (BAC library was screened with previously assigned microsatellites using a sheep-hamster hybrid panel and genetic linkage. Thirty-three BACs were obtained, fluorescently labelled and hybridised on sheep-goat hybrid metaphases (2n = 57. This study allowed us, (i, to anchor all linkage groups on sheep chromosomes, (ii, to give information on the probable position of the centromere on the linkage map for the centromeric chromosomes, (iii, to contradict the previous orientation of the ovine × linkage group by the mapping of BMS1008 on OARXq38. Concerning our somatic cell hybrid panel, this study resulted in the assignment of all the previously unassigned groups to ovine chromosomes and a complete characterisation of the hybrid panel. In addition, since hybridisations were performed on a sheep-goat hybrid, new marker/anchoring points were added to the caprine cytogenetic map.

    Full Text Available Abstract Background Toxoplasma gondii is a major problem for the sheep industry as it may cause reproduction problems. The importance of T. gondii in Norwegian goat herds is uncertain, but outbreaks of toxoplasmosis in dairy goat farms have been recorded. The aim of this study was to describe the prevalence of T. gondii infection in Norwegian dairy goats by using serology. Findings Goat serum originally collected as part of two nationwide surveillance and control programmes between 2002 and 2008 were examined for T. gondii antibodies by using direct agglutination test. In total, 55 of 73 herds (75% had one or more serologically positive animals, while 377 of 2188 (17% of the individual samples tested positive for T. gondii antibodies. Conclusions This is the first prevalence study of T. gondii infection in Norwegian goats. The results show that Norwegian goat herds are commonly exposed to T. gondii. Nevertheless, the majority of goat herds have a low prevalence of antibody positive animals, which make them vulnerable to infections with T. gondii during the gestation period.

    Clostridium perfringens type D-producing epsilon toxin is a common cause of death in sheep and goats worldwide. Although anti-epsilon toxin serum antibodies have been detected in healthy non-vaccinated sheep, the information regarding naturally acquired antibodies in ruminants is scanty. The objective of the present report was to characterize the development of naturally acquired antibodies against C. perfringens epsilon toxin in goats. The levels of anti-epsilon toxin antibodies in blood serum of goat kids from two different herds were examined continuously for 14 months. Goats were not vaccinated against any clostridial disease and received heterologous colostrums from cows that were not vaccinated against any clostridial disease. During the survey one of these flocks suffered an unexpectedly severe C. perfringens type D enterotoxemia outbreak. The results showed that natural acquired antibodies against C. perfringens epsilon toxin can appear as early as 6 weeks in young goats and increase with the age without evidence of clinical disease. The enterotoxemia outbreak was coincident with a significant increase in the level of anti-epsilon toxin antibodies. PMID:18538416

    Full Text Available Abstract Background The goat (Capra hircus represents one of the most important farm animal species. It is reared in all continents with an estimated world population of about 800 million of animals. Despite its importance, studies on the goat genome are still in their infancy compared to those in other farm animal species. Comparative mapping between cattle and goat showed only a few rearrangements in agreement with the similarity of chromosome banding. We carried out a cross species cattle-goat array comparative genome hybridization (aCGH experiment in order to identify copy number variations (CNVs in the goat genome analysing animals of different breeds (Saanen, Camosciata delle Alpi, Girgentana, and Murciano-Granadina using a tiling oligonucleotide array with ~385,000 probes designed on the bovine genome. Results We identified a total of 161 CNVs (an average of 17.9 CNVs per goat, with the largest number in the Saanen breed and the lowest in the Camosciata delle Alpi goat. By aggregating overlapping CNVs identified in different animals we determined CNV regions (CNVRs: on the whole, we identified 127 CNVRs covering about 11.47 Mb of the virtual goat genome referred to the bovine genome (0.435% of the latter genome. These 127 CNVRs included 86 loss and 41 gain and ranged from about 24 kb to about 1.07 Mb with a mean and median equal to 90,292 bp and 49,530 bp, respectively. To evaluate whether the identified goat CNVRs overlap with those reported in the cattle genome, we compared our results with those obtained in four independent cattle experiments. Overlapping between goat and cattle CNVRs was highly significant (P Conclusions We describe a first map of goat CNVRs. This provides information on a comparative basis with the cattle genome by identifying putative recurrent interspecies CNVs between these two ruminant species. Several goat CNVs affect genes with important biological functions. Further studies are needed to evaluate the

    Adhesion to gut tissues and colonization of the alimentary tract, two important stages in the pathogenesis of Salmonella, are mediated by FimH adhesin of type 1 fimbriae. It was suggested that minor differences in the structure of FimH are most likely associated with differences in adhesion specificities, and may determine the tropism of various Salmonella serovars to different species and tissues. We investigated this hypothesis by comparing the binding properties of FimH proteins from three Salmonella enterica serovars with limited (Choleraesuis, Dublin) or restricted (Abortusovis) host ranges to FimH from broad host range S. Enteritidis and mannose inactive FimH from S. Gallinarum. Although all active variants of FimH protein were able to bind mannose-rich glycoproteins (RNase B, HRP and Man-BSA) with comparable affinity measured by surface plasmon resonance, there were significant differences in the binding profiles of the FimH proteins from host restricted serovars and host unrestricted serovar Enteritidis, to glycoproteins from enterocyte cell lines established in vitro and derived from sheep, pig and cattle. When low-binding FimH adhesin from S. Enteritidis was subjected to Western blot analysis, it bound to surface membrane protein of about 130 kDa, and high-binding FimH adhesins from S. Abortusovis, S. Choleraesuis and S. Dublin bound to surface membrane protein of about 55 kDa present in each cell line. Differential binding of FimH proteins from host-restricted and broad-host-range Salmonella to intestinal receptors was confirmed using mutant FimH adhesins obtained by site-directed mutagenesis. It was found that the low-binding variant of FimH from S. Choleraesuis with mutation Leu57Pro lost the ability to bind protein band of 55 kDa, but instead interacted with glycoprotein of about 130 kDa. On the other hand, the high-binding variant of FimH adhesin from S. Enteritids with mutation Asn101Ser did not bind to its receptor of 130 kDa, but instead it

    A vaccination trial involving 72 goats was designed to compare the epsilon antitoxin titres and local reactions at the injection sites, of two commercial enterotoxemia vaccines. Three dosage regimens were used for each vaccine (12 goats per group). Although no significant differences were noted in humoral immune response between the two vaccines (P = 0.05), one vaccine regime resulted in low titres (P = 0.05) on two occasions. Local tissue reactions at injection sites persisted for six months in 53% of the goats regardless of vaccine used or dosage administered. No immunological basis for the reported differences in vaccine efficacy between sheep and goats was observed in this trial. PMID:6309346

    Full Text Available Annual world sheep milk production is estimated at the level of 8.2 million tons and constitutes 1.5% of the total milk production obtained from various species of mammals. Majority of this milk is used to manufacture cheeses and fermented beverages. These products are commonly considered as regional articles and are protected by legal regulations which guarantee their taste and aroma typical for a given region and which they owe to traditional production technologies. In Poland, sheep are reared, primarily, in mountainous areas (Podhale, Bieszczady but also in Wielkopolska and Podlasie. The sheep population in Poland is estimated at 223 000 animals but milk is obtained only from a small number of animals and its annual production is assessed at the level of 1000 t. The nutritional value of sheep milk is higher in comparison with goat or cow milk. Sheep milk protein is characterised by a high biological value comparable with the biological value of the whole chicken egg. In addition, products manufactured from sheep milk possess high nutritive value. Due to its rich chemical composition, sheep milk provides an excellent raw material for processing into maturing soft and hard cheeses (75-80% of protein is casein, for fermented beverages, both natural and with different tastes, as well as butter, ghee and ice-cream. High proportion of dry matter (up to 18% found in sheep milk does not require application of any thickeners in production of fermented beverages. That is why these beverages are fully natural and free of additives.

    Full Text Available In Sardinia, goat farming is a very important resource. Sarda and Maltese breed are reared mainly for milk production and for suckling kids meat, while meat from adult goats is undervalued. The use of adult goat meat to obtain ripened ham will contribute to safeguard the Sardinian goat supply chain. The aim of the present study was to characterize Sarda and Maltese goat dry ham in order to evaluate the quality of autochthonous goat breed meat. Chemical-physical characteristics were determined dur-ing the production stages, while the rheological and colour parameters and the composition of the goat ham were determined at the end of ripening. The pH evolution during processing were similar to other cured meat products, e.g. sheep hams, even though the values were high, especially in the products from Sarda breed. The aw value regularly decreased during processing. Colour parameters (L*, a*, b* in the hams from Maltese goat breed were significantly (P<0.05 higher than in those from Sarda. The Sarda goat ham showed a significantly lower percentage of moisture (42% vs 52%, an higher protein content (44.35% vs 34.19%, while no differences were pointed out in the total fat content. Among the ham rheological properties, hardness parameters showed higher levels (13850.22±7589.92 vs 11073.99±6481.31, respectively in Sarda and Maltese hams in comparison to similar products from pork and sheep, while adhesiveness value was lower. The results show that the quality parameters of goat ripened hams are affected mainly by the charac-teristics of the goat meat, in relation on the breed and the breeding system, and, less, by the traditional technology.

    Full Text Available Abstract Background The aim of this study was to estimate the seroprevalence of Coxiella burnetii in dairy goat farms in the Netherlands and to identify risk factors for farm and goat seropositivity before mandatory vaccination started. We approached 334 eligible farms with more than 100 goats for serum sampling and a farm questionnaire. Per farm, median 21 goats were sampled. A farm was considered positive when at least one goat tested ELISA positive. Results In total, 2,828 goat serum samples from 123 farms were available. Farm prevalence was 43.1% (95%CI: 34.3%-51.8%. Overall goat seroprevalence was 21.4% (95%CI: 19.9%-22.9% and among the 53 positive farms 46.6% (95%CI: 43.8%-49.3%. Multivariable logistic regression analysis included 96 farms and showed that farm location within 8 kilometres proximity from a bulk milk PCR positive farm, location in a municipality with high cattle density (≥ 100 cattle per square kilometre, controlling nuisance animals through covering airspaces, presence of cats or dogs in the goat stable, straw imported from abroad or unknown origin and a herd size above 800 goats were independent risk factors associated with Q fever on farm level. At animal level almost identical risk factors were found, with use of windbreak curtain and artificial insemination as additional risk factors. Conclusion In 2009-2010, the seroprevalence in dairy goats in the Netherlands increased on animal and farm level compared to a previous study in 2008. Risk factors suggest spread from relatively closely located bulk milk-infected small ruminant farms, next to introduction and spread from companion animals, imported straw and use of artificial insemination. In-depth studies investigating the role of artificial insemination and bedding material are needed, while simultaneously general biosecurity measures should be updated, such as avoiding companion animals and vermin entering the stables, next to advice on farm stable constructions on

  3. PrPSc spreading patterns in the brain of sheep linked to different prion types

    2011-02-01

    Full Text Available Abstract Scrapie in sheep and goats has been known for more than 250 years and belongs nowadays to the so-called prion diseases that also include e.g. bovine spongiform encephalopathy in cattle (BSE and Creutzfeldt-Jakob disease in humans. According to the prion hypothesis, the pathological isoform (PrPSc of the cellular prion protein (PrPc comprises the essential, if not exclusive, component of the transmissible agent. Currently, two types of scrapie disease are known - classical and atypical/Nor98 scrapie. In the present study we examine 24 cases of classical and 25 cases of atypical/Nor98 scrapie with the sensitive PET blot method and validate the results with conventional immunohistochemistry. The sequential detection of PrPSc aggregates in the CNS of classical scrapie sheep implies that after neuroinvasion a spread from spinal cord and obex to the cerebellum, diencephalon and frontal cortex via the rostral brainstem takes place. We categorize the spread of PrPSc into four stages: the CNS entry stage, the brainstem stage, the cruciate sulcus stage and finally the basal ganglia stage. Such a sequential development of PrPSc was not detectable upon analysis of the present atypical/Nor98 scrapie cases. PrPSc distribution in one case of atypical/Nor98 scrapie in a presumably early disease phase suggests that the spread of PrPSc aggregates starts in the di- or telencephalon. In addition to the spontaneous generation of PrPSc, an uptake of the infectious agent into the brain, that bypasses the brainstem and starts its accumulation in the thalamus, needs to be taken into consideration for atypical/Nor98 scrapie.

    Full Text Available In the period from July 2009 to October 2010, fecal samples from 61 animals and 154 humans from the municipality of Aracatuba (São Paulo State, Brazil were studied. Fecal samples from animals were collected in the Municipal Animal Shelter and the Veterinary Hospital of the Universidade Estadual Paulista. Human fecal specimens were collected in playschools in the outskirts of the city by the private network of clinical analysis laboratories of the municipal. Diagnosis was done by optical microscopy using the Faust and Hoffmann, Pons and Janer techniques. The genotypes of Giardia intestinalis were characterized by PCR-RFLP and confirmed by sequencing the ß-giardin gene. Human specimens were positive in 25.3% (39/154 of the cases with 26.8% (36/134 of the specimens from children and 15% (3/20 from adults being positive. The frequency of G. intestinalis among the animals was 23.0% (14/61. A total of 32 isolates of G. intestinalis obtained from human feces and six from dogs and cats were characteristic of the A genotype (AI and AII/AIII. The results of this study in respect to frequency of giardiasis are similar to reported in most studies in Brazil. The prevalence observed in animal populations conforms to worldwide infection rates. G. intestinalis genotypes considered zoonotic were detected in both pets and humans from the city of Aractuba, suggesting a possible zoonotic transmission of the parasite in the northwestern region of São Paulo State. The absence of these genotypes in farm animals may imply that they are not involved in the chain of transmission to humans in this region.

  9. Immunogenic effects of irradiated Haemonchus contortus larvae in goats

    International Nuclear Information System (INIS)

    Development of radiation-attenuated vaccines against parasitic disease has been reported in literature. Use of irradiated larvae as vaccines enables advantage to be taken of the special immunological properties of living parasites; radiation treatment can largely suppress the pathogenic effects of the vaccines and the reproductive capacity of the parasites involved. Attempts to produce a radiation-attenuated vaccine against Haemonchus contortus infection in adult goats are discussed here. H. contortus infection in ruminants is prevalent in the Philippines, especially among cattle and goats. The results presented indicate that a certain degree of resistance against H. contortus infection can be induced in adult goats immunized with irradiated larvae. The shelf-life of the vaccine was also determined. (author)

    In evaluating speaker verification systems, asymmetries have been observed in the ease with which people are able to break into other people`s voice locks. People who are good at breaking into voice locks are called wolves, and people whose locks are easy to break into are called sheep. (Goats are people that have a difficult time opening their own voice locks.) Analyses of speaker verification algorithms could be used to understand wolf/sheep asymmetries. Using the notion of a ``speaker space``, it is demonstrated that such asymmetries could arise even though the similarity of voice 1 to voice 2 is the same as the inverse similarity. This explains partially the wolf/sheep asymmetries, although there may be other factors. The speaker space can be computed from interspeaker similarity data using multidimensional scaling, and such speaker space can be used to given a good approximation of the interspeaker similarities. The derived speaker space can be used to predict which of the enrolled speakers are likely to be wolves and which are likely to be sheep. However, a speaker must first enroll in the speaker key system and then be compared to each of the other speakers; a good estimate of a person`s speaker space position could be obtained using only a speech sample.

    Full Text Available Since poisoning by Senecio spp. is one of the main causes of cattle death in southern Brazil, control of these plants is a priority for the local livestock production. After the pasture has been mowed, grazing by 16 sheep was efficient for controlling Senecio brasiliensis and Senecio madagascariensis populations in a 5.5-hectare area that had long been severely infested with these species. A total of 28,629 plants among S. brasiliensis (flower-of-souls, 10,122 and S.madagascariensis (fireweed, 18,507 were almost completely eliminated in a two-year period. The number of sheep was kept at 3.0 stock units/ha, but a variable number of cattle were temporarily stocked according to pasture availability. The major sanitary practice applied to the sheep was anthelmintic administration. Liver biopsies taken from sheep and cattle before and after experimental period didn't reveal any change associable with seneciosis. The performance levels of the sheep were comparable to those observed in flocks managed under traditional extensive grazing systems in southern Brazil.

    Goat Meat (chevon) has been used as a source of protein and its demand for consumption is increasing yearly in Malaysia. The objective of the research was to determine proximate composition namely moisture, protein, fat and ash level in chevon from different type of breed i.e. Boer and Katjang. The goat breed proximate analyses were compared with sheep meat (mutton). The results for goat breeds were showing that the percentage of moisture, fat, protein and ash were of 73.06 - 74.99, 2.76 - 2.94, 20.81 - 22.47 and 0.97 - 1.21 respectively. Meanwhile the concentration of moisture, fat, protein and ash for mutton were 73.52, 5.06, 22.50 and 1.17 respectively. The pilot study on perception survey indicated that the highest respondent percentage on consumption of chevon was once in a month. Based on the survey, Boer was the most known breed compared to the other breed. Majority of respondents reported that chevon was fairly expensive meat but easier to obtain in the survey area.

    Full Text Available Somatic cell count (SCC in monitoring udder health has been described in numerous studies as a useful method for the diagnosis of intramammary infection (IMI, and it is considered in standards of quality and hygiene of cow’s milk in many countries. However, several authors have questioned the validity of SCC as a reliable IMI diagnosis tool in dairy goats. This review attempts to reflect the importance of different infectious and non-infectious factors that can modify SCC values in goat milk, and must, therefore, be taken into account when using the SCC as a tool in the improvement of udder health and the quality of milk in this species. In dairy goats, some investigations have shown that mammary bacterial infections are a major cause of increased SCC and loss of production. In goats however, the relationship between bacterial infections and SCC values is not as simple as in dairy cattle, since non-infectious factors also have a big impact on SCC. Intrinsic factors are those that depend directly on the animal: time and number of lactation (higher SCC late in lactation and in aged goats, prolificity (higher SCC in multiple births, milking time (higher SCC in evening compared to morning milking and number of milkings per day, among others. Extrinsic factors include: milking routine (lower SCC in machine than in manual milking, seasonality and food. In addition, milk secretion in goats is mostly apocrine and therefore characterized by the presence of epithelial debris or cytoplasmic particles, which makes the use of DNA specific counters mandatory. All this information is of interest in order to correctly interpret the SCC in goat milk and to establish differential SCC standards.

    A quantitative PCR, based on the gene encoding Babesia ovis Surface Protein D (BoSPD) was developed and applied to investigate the presence of Babesia ovis (B. ovis) in its principal vector, the tick Rhipicephalus bursa (R. bursa), and in the ovine host. Quantification of B. ovis in experimentally-infected lambs showed a sharp increase in parasitemia 10-11days in blood-inoculated and adult tick-infested lambs, and 24days in a larvae-infested lamb. A gradual decrease of parasitemia was observed in the following months, with parasites detectable 6-12 months post-infection. Examination of the parasite load in adult R. bursa during the post-molting period using the quantitative PCR assay revealed a low parasite load during days 2-7 post-molting, followed by a sharp increase, until day 11, which corresponded to the completion of the pre-feeding period. The assay was then used to detect B. ovis in naturally-infected sheep and ticks. Examination of samples from 8 sheep and 2 goats from infected flocks detected B. ovis in both goats and in 7 out of the 8 sheep. Additionally, B. ovis was detected in 9 tick pools (5 ticks in each pool) and two individual ticks removed from sheep in infected flocks. PMID:27084469

  15. Detection of prions in the faeces of sheep naturally infected with classical scrapie

    2011-05-01

    Full Text Available Abstract Classical scrapie is a naturally transmitted prion disease of sheep and goats. Contaminated environments may contribute to the spread of disease and evidence from animal models has implicated urine, blood, saliva, placenta and faeces as possible sources of the infection. Here we sought to determine whether sheep naturally infected with classical scrapie shed prions in their faeces. We used serial protein misfolding cyclic amplification (sPMCA along with two extraction methods to examine faeces from sheep during both the clinical and preclinical phases of the disease and showed amplification of PrPSc in 7 of 15 and 14 of 14 sheep respectively. However PrPSc was not amplified from the faeces of 25 sheep not exposed to scrapie. These data represent the first demonstration of prion shedding in faeces from a naturally infected host and thus a likely source of prion contamination in the environment.

    Full Text Available Researches were carried out at the Institute of Research and Development for Sheep and Goat Breeding from Palas - Constanta, situated in Eastern Romania. A comparative study was implemented concerning body development of four adult goat genotypes, as follows: Carpatina purebreds (n=25 and 74 crossbred goats, with different gene inputs from the South African Boer breed, F1 Boer x Carpatina, R1 Boer x (Boer x Carpatina and R1 Carpatina x (Carpatina x Boer. In order to evaluate the body development of the adult goats from the four genotypes, several body measurements were taken, following aspects such as the animal's height and body length, width and circumference measurements, with the purpose to calculate indices which to define the hindquarter's muscling indexes. Results have shown that between the Carpatina goats and those with 25% input genes from the Boer breed, the differences regarding the body weight and muscling indexes were not significant (p>0.05. F1 Boer x Carpatina crossbreeds had the body width and the hindquarters muscling indexes significantly higher (p≤0.001 in both does and bucks, when compared to Carpatina. R1 goats having 75% input genes from the Boer breed had significantly higher (p≤0.001 body measurements when concerning the hindquarters muscling indexes, compared to Carpatina purebreds. Results suggest that Boer back-crossing the indigenous Carpatina has the potential to increase both quantity and quality of the goat meat production.

    2015-06-01

    Full Text Available The current study aimed to characterize the gross and microscopic structures of the interdigital sinus in Egyptian native breeds of sheep and goats (Baladi sheep and goats to aid in conducting farther studies on such sinus and its surgical importance. The study was carried out on the distal fore and hind limb specimens (below the fetlock joint obtained from healthy mature ten Baladi sheep and ten Baladi goats of both sexes. For sheep, thirty specimens were subjected to gross anatomical investigation and the other ten specimens were used for histological examination. While, the forty goats fore and hind feet specimens were examined grossly. The results obtained revealed the presence of a well-developed interdigital sinus in Baladi sheep, but there was no evidence for the existence of this unique structure in all examined specimens of Baladi goats. Such sinus appeared grossly as a pipe-like, composed of two parts; body (corpus and neck (column which opened in the skin of the interdigital area with an external orifice. The body consisted of three distinct parts in the forefeet and a single part in the hind feet. Histologically, the wall in body and neck regions of the interdigital sinus composed of three distinct layers; epidermis, dermis and a fibrous capsule. Many sebaceous glands, hair follicles and sweat glands in addition to the glandular apocrine gland were distributed within the dermis. The secretory adenomers of the interdigital sinus arranged in different lobules and lined with cuboidal cells with bleb-like projections. It reacted positively with Periodic Acid Schiff (PAS, Sudan black and Sudan III stains, on the other hand it negatively reacted with Alcian blue stain (AB.

    A complex of various malformations in newborns was observed to an increased extent in sheep farms in the 2011/2012 lambing season. An intrauterine Schmallenberg virus (SBV) infection was identified as the cause of these malformations. To date, a detailed pathological description of the deformity complex has only been given for bovine and ovine newborns.The aim of this study was therefore to provide a description of pathologic-anatomical congenital malformations in goat kids caused by intrauterine SBV infection. To this end, pathologic-anatomical and molecular biological investigations by PCR were carried out on 37 goat kids and 457 lambs from 238 sheep and goat farms in order to carry out an interspecies comparison. Of the 37 goat kids dissected, it was possible to identify a SBV infection in twelve animals (32.4%) by RT-PCR. In nine animals (24.3%) displaying pathological-anatomical malformations SBV could not be detected by PCR. The following malformations were observed: athrogryposis, deformation of spinal column, torticollis, asymmetry of the skull, brachygnathia inferior, cerebellar hypoplasia, cerebellar aplasia and internal hydrocephalus. Arthogryposis was the most common malformation, both in animals with positive PCR results and those with negative PCR results. This study documents congenital malformations caused by an intrauterine SBV infection for the first time on a large number of newborn goats. PMID:24693655

  3. Genetic resistance to infections in sheep.

    Bishop, S C

    2015-12-14

    This paper considers genetic resistance to infectious disease in sheep, with appropriate comparison with goats, and explores how such variation may be used to assist in disease control. Many studies have attempted to quantify the extent to which host animals differ genetically in their resistance to infection or in the disease side-effects of infection, using either recorded animal pedigrees or information from genetic markers to quantify the genetic variation. Across all livestock species, whenever studies are sufficiently well powered, then genetic variation in disease resistance is usually seen and such evidence is presented here for three infections or diseases of importance to sheep, namely mastitis, foot rot and scrapie. A further class of diseases of importance in most small ruminant production systems, gastrointestinal nematode infections, is outside the scope of this review. Existence of genetic variation implies the opportunity, at least in principle, to select animals for increased resistance, with such selection ideally used as part of an integrated control strategy. For each of the diseases under consideration, evidence for genetic variation is presented, the role of selection as an aid to disease control is outlined and possible side effects of selection in terms of effects in performance, effects on resistance to other diseases and potential parasite/pathogen coevolution risks are considered. In all cases, the conclusion is drawn that selection should work and it should be beneficial, with the main challenge being to define cost effective selection protocols that are attractive to sheep farmers.

    2011-01-01

    Full Text Available Fasciolosis is a disease that affects the liver parenchyma and bile ducts of numerous animals, including humans, which causes economic losses and threatens public health. The present work aimed at reporting the distribution and factors connected with Fasciola hepatica infection in cattle in ten municipalities in southern Espírito Santo, Brazil, between 2008 and 2009. During this period, 50 rural properties in ten cities were analyzed and fecal samples from 10% of the cattle on each farm were collected. Of the 717 samples analyzed, 154 (21.33% presented Fasciola hepatica eggs. As for the 50 rural properties studied, 32 (64% had animals positive for fasciolosis. Throughout the evaluation, it was observed that 42 (84% rural properties had flooded areas, 33 (66% were located at altitudes less than 226 meters, in 36 (72% mollusks were found, 47 (94% had other definitive hosts (horses, sheep, goats and 25 (50% had previous cases of bovine fasciolosis. The present results showed a high rate of bovine fasciolosis in the analyzed region whereas infected animals are present in all the municipalities. Based on statistical analysis, it was concluded that there was an association between the presence of flooded areas and other definitive hosts in rural properties where bovine fasciolosis was detected.

    Full Text Available Paratuberculosis, caused by Mycobacterium avium subsp. paratuberculosis (MAP, is a chronic incurable infection of intestinal tract of animals. The study took place in 2012, on 491 Korean black goats, older than 2 years, from goat herds located in Southern region, Korea. The animals were sampled and tested for paratuberculosis. Enzyme-linked immunosorbent assay and microbiological culture were used to investigate MAP infection. Among the 491 goats from 100 herds screened, 4 (0.8% and 3 (0.6% goats were defined positive for MAP by ELISA and faecal culture, respectively. Isolated colonies were confirmed as MAP by IS900-PCR, and genotyped by IS1311 PCR-REA assays. The results revealed MAP infection at a low prevalence rate with "cattle type" and "bison type" genotypes.

    The Global Earth Observation Integrated Data Environment (GEO-IDE) is NOAA's effort to successfully integrate data and information with partners in the national US-Global Earth Observation System (US-GEO) and the international Global Earth Observation System of Systems (GEOSS). As part of the GEO-IDE, the Unified Access Framework (UAF) is working to build momentum towards the goal of increased data integration and interoperability. The UAF project is moving towards this goal with an approach that includes leveraging well known and widely used standards and focusing initially on well understood data types, such as gridded data from climate models. This phased approach serves to engage data providers and users and also has a high probability of demonstrable successes. The UAF project shares the widely held conviction that the use of data standards is a key ingredient necessary to achieve interoperability. Many community-based consensus standards fail, though, due to poor compliance. Compliance problems emerge for many reasons: because the standards evolve through versions, because documentation is ambiguous or because individual data providers find the standard inadequate as-is to meet their special needs. In addition, minimalist use of standards will lead to a compliant service, but one which is of low quality. For example, serving five hundred individual files from a single climate model might be compliant, but enhancing the service so that those files are all aggregated together into one virtual dataset and available through a single access URL provides a much more useful service. The UAF project began showcasing the advantages of providing compliant data by manually building a master catalog generated from hand-picked THREDDS servers. With an understanding that educating data managers to provide standards compliant data and metadata can take years, the UAF project wanted to continue increasing the volume of data served through the master catalog as much as possible. However, it quickly became obvious, through the sheer volume of data servers available, that the manual process of building a master catalog was not scalable. Thus, the idea for the catalogCleaner tool was born. The goal of this tool is to automatically crawl a remote OPeNDAP or THREDDS server, and from the information in the server build a "clean" catalog of data that will be: a) served through uniform access services; b) have CF compliant metadata; c) directly link the data to common visualization tools thereby allowing users to immediately begin exploring actual data. In addition, the UAF-generated clean catalog can then be used to drive data discovery tools such as Geoportal, GI-CAT, etc. This presentation will further explore the motivation of creating this tool, the implementation of this tool, as well as the myriad of challenges and difficulties there were encountered along the way.

  12. Healthy goats naturally devoid of prion protein

    Benestad Sylvie L

    2012-12-01

    Full Text Available Abstract Prion diseases such as scrapie in small ruminants, bovine spongiform encephalopathy (BSE in cattle and Creutzfeldt-Jakob disease (CJD in man, are fatal neurodegenerative disorders. These diseases result from the accumulation of misfolded conformers of the host-encoded prion protein (PrP in the central nervous system. To date naturally-occurring PrP free animals have not been reported. Here we describe healthy non-transgenic animals, Norwegian Dairy Goats, lacking prion protein due to a nonsense mutation early in the gene. These animals are predicted to be resistant to prion disease and will be valuable for research and for production of prion-free products.

  14. Morphological identification of parasitic nematode infective larvae of small ruminants and cattle: A practical lab guide

    Directory of Open Access Journals (Sweden)

    Jan A. van Wyk

    2013-03-01

    Full Text Available In 2004, a new concept was introduced for simplifying identification of larvae of the common nematodes of cattle, sheep and goats that comprises estimates of the lengths of the sheath tail extensions of infective third-stage larvae (L3 of each genus and/or species to that of Trichostrongylus spp., instead of having to be dependent only on measurements in micrometre. For example, if the mean length of the sheath tail extension (the extension of the sheath caudad, beyond the caudal tip of the larva of Trichostrongylus colubriformis and Trichostrongylus axei is assumed to be ‘X’, then that ofHaemonchus contortus is 2.0–2.7 ‘X’ – a difference that is not difficult to estimate. An additional new approach suggested now, particularly for L3 of species and/or genera difficult to differentiate (such as Chabertia ovina and Oesophagostomum columbianum, is to estimate the proportion of the larval sheath tail extension comprising a terminal thin, whip-like filament. For the experienced person, it is seldom necessary to measure more than one or two sheath tail extensions of L3 in a mixed culture, because the identity of most of the remaining L3 can thereafter be estimated in relation to those measured, without having to take further measurements. The aim of this article was to present the novel approach in the form of a working guide for routine use in the laboratory. To facilitate identification, figures and a separate organogram for each of small ruminants and cattle have been added to illustrate the distinguishing features of the common L3.

    Although the use of tanniferous plants or condensed tannins as an alternative to anthelmintics to control gastrointestinal nematodes has been largely documented in sheep, studies remain scarce in goats. The objective of this study was therefore to assess the possible impact of condensed tannins in goats infected with adult Haemonchus contortus. Two groups of cull goats were experimentally infected with 10.000 L3 of H. contortus. After 4 weeks, quebracho extracts, representing 5% of the diet DM, were administered for 8 days to one of the two groups. Goats of the second group remained as controls. One week after the end of quebracho administration, the goats were euthanised. Individual egg excretion and pathophysiological parameters were measured weekly during the study. At the end of the study, worm counts were assessed and histological samples from the abomasa were taken to count the numbers of mucosal mast cells, globule leukocytes and eosinophils. The administration of tannins was associated with a significant decrease in egg excretion, which persisted until the end of experiment. This reduction was not associated with any difference in worm number but with a significant decrease in female fecundity. No significant changes in the mucosal density of the three inflammatory cell types were detected between the two groups. These results indicate that the major consequence of tannin consumption in goats is a reduction in worm fecundity and egg output, which does not seem related to significant changes in the local mucosal response.

    Bovine viral diarrhea virus (BVDV) is one of the most important viral pathogens of livestock and causes substantial economic losses to the livestock industry worldwide. BVDV is not necessarily species specific and is known to infect domesticated and wild ruminants. In the present study, BVDV infection was identified in two Saanen goats from one farm, and two different viral subtypes were found, BVDV-1a and BVDV-2a. Each isolate was closely related to cattle isolates identified in the Republic of Korea. The two sequences obtained in this study were not consistent with border disease virus (BDV). The incidence of BVDV in this farm apparently occurred in the absence of contact with cattle and may be associated with grazing. This study demonstrates that BVDV infection may be possible to transmit among goats without exposure to cattle. Therefore, this result indicates that Saanen goats may act as natural reservoirs for BVDV. This is the first report of BVDV-1a infection in a Saanen goat. PMID:26992733

    Full Text Available BACKGROUND: Liaoning cashmere goat is a famous goat breed for cashmere wool. In order to increase the transcriptome data and accelerate genetic improvement for this breed, we performed de novo transcriptome sequencing to generate the first expressed sequence tag dataset for the Liaoning cashmere goat, using next-generation sequencing technology. RESULTS: Transcriptome sequencing of Liaoning cashmere goat on a Roche 454 platform yielded 804,601 high-quality reads. Clustering and assembly of these reads produced a non-redundant set of 117,854 unigenes, comprising 13,194 isotigs and 104,660 singletons. Based on similarity searches with known proteins, 17,356 unigenes were assigned to 6,700 GO categories, and the terms were summarized into three main GO categories and 59 sub-categories. 3,548 and 46,778 unigenes had significant similarity to existing sequences in the KEGG and COG databases, respectively. Comparative analysis revealed that 42,254 unigenes were aligned to 17,532 different sequences in NCBI non-redundant nucleotide databases. 97,236 (82.51% unigenes were mapped to the 30 goat chromosomes. 35,551 (30.17% unigenes were matched to 11,438 reported goat protein-coding genes. The remaining non-matched unigenes were further compared with cattle and human reference genes, 67 putative new goat genes were discovered. Additionally, 2,781 potential simple sequence repeats were initially identified from all unigenes. CONCLUSION: The transcriptome of Liaoning cashmere goat was deep sequenced, de novo assembled, and annotated, providing abundant data to better understand the Liaoning cashmere goat transcriptome. The potential simple sequence repeats provide a material basis for future genetic linkage and quantitative trait loci analyses.

    Full Text Available Different species of Panicum, including P. dichotomiflorum,have been reported as a cause of photosensitization in sheep, horses, cattle and goats. An outbreak of hepatogenous photosensitization occurred in 3 flocks of hair sheep in the Brazilian semiarid region. Eighty one out of 365 sheep were affected and 39 died. The main affected animals were nursing lambs and sheep younger than one year old. Donkeys, goats and cattle grazing in the same pasture were not affected. Clinical signs were edema of the head, followed by dermatitis, mainly in the face, ears, and croup, ocular discharge, corneal opacity with blindness, and redness of the coronary band and hoof. At necropsy of one affected lamb the liver was yellowish. Upon histologic examination scattered necrotic hepatocytes were observed in the liver and focal areas of necrosis of myocytes appeared in the heart. Samples of P. dicotomiflorum were analyzed by TLC and those containing saponins were isolated by HPLC using RP-C18 column and eluted with a mixture of MeOH and H2O. The isolated compounds were submitted to ¹H and 13C NMR spectroscopy. Reactions were positive to furostanol saponins with the same Rf of the standard protodioscin (0.21 and methylprotodioscin (0.32. The spectroscopic results indicated a mixture of (25R- and (25S-protodioscin isomers in a proportion of 3:1, and methylprotodioscin.Diferentes espécies de Panicum, incluindo P. dichotomiflorum,causam fotossensibilização em ovinos, eqüinos, bovinos e caprinos. Um surto de fotossensibilização hepatógena ocorreu em 3 rebanhos de ovinos no município de Casa Nova, Bahia. Oitenta e um de 365 ovinos adoeceram e 39 morreram. Cordeiros lactentes e ovinos de menos de um ano foram mais afetados. Jumentos, cabras e bovinos que permaneciam nas mesmas pastagens não foram afetados. Clinicamente observou-se edema da face, seguido por dermatite, principalmente da face, orelhas e garupa, corrimento ocular, opacidade da córnea com cegueira

    Full Text Available Dung beetles (Coleoptera, Scarabaeinae attracted to sheep dung in exotic pastures. In this study we provide data on the abundance and richness of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae attracted to sheep dung in exotic pastures (Brachiaria spp.. In four areas of exotic pasture pitfall traps were installed and baited with fresh sheep dung for sampling of dung beetles. A total of 2,290 individuals were captured belonging to 16 species, 10 genera and five tribes of Scarabaeinae beetles. Trichillum externepunctatum Preudhomme de Borre, 1886 and Dichotomius bos (Blanchard, 1843 were dominant. The guild of dwellers was the most abundant in pastures. We demonstrate that dung beetles are attracted to sheep dung. Since the production of both cattle and sheep in the same area is common in tropical pasturelands, results obtained here highlight the need to investigate the actual role of dung sharing (cattle dung + sheep dung by dung beetles. It is also suggested that experiments be performed for evaluation of the ecological functions performed by dung beetles using sheep dung.

    The goat whey proteome has been explored in depth via capture with combinatorial peptide ligand libraries (CPLLs) at three different pH values. A total of 452 unique species have been tabulated, a proteome discovery so far unmatched in any single other investigation of milk from any mammalian species. This massive discovery is probably related to: i) the extraordinary load of proteins onto the CPLL beads (i.e. 2 g for each different pH captures) vs. barely 100 μL of beads; ii) the high resolution/high mass accuracy of mass spectral data; and iii) the use of two complementary tools, Mascot and PEAKS, each one contributing to a set of unique protein IDs. Due to the relative paucity of available protein annotations for goat, only 10% of the identified proteins belong to the capra, whereas 52% are specific of sheep and 37% are homologous to that of bovine milk. This work reports the largest description so far of the goat milk proteome, which has been compared with cow's milk proteome and would thus help to understand the importance of low-abundance proteins with respect to the unique biological properties of this nutrient.

    The aim of this study was to determine the genetics of polymorph systems of Transferrin in Garole sheep breed. The present study was conducted on 95 adult Garole sheep comprising 52 ewes and 43 rams, maintained at Sheep and Goat Breeding Farm of West Bengal University of Animal and Fishery Sciences, West Bengal, during the period from April-September, 2009. The polymorphism of transferrin was determined through SDS-Polyacrylamide gel electrophoresis technique. It was found that the transferrin type was controlled by five codominant alleles (TfA, TfB, TfC TfD and TfE) in Garole sheep. These five alleles, because of co-dominant nature of inheritance, determined the occurrence of nine transferrin genotypes in the analyzed flock. Four (TfAA, TfBB, TfCC and TfDD) of these were homozygous and the remaining five (TfAD, TfBC, TfBD, TfCD and TfDE) heterozygous. It was found that the TfDD genotype (0.263) was predominant while TfDE genotype (0.042) was least common in the analyzed flock. Frequencies of other genotypes were as: TfCD(0.242), TfBD(0.126), TfCC(0.084), TfBB(0.074), TfAA(0.063), TfAD and TfBC (0.053 for each genotype ) in whole population. From the result it was found that in whole population combined, the heterozygotic genotypic frequency (0.516) was more than that of homozygotic genotypic frequency (0.484). Considerable variations were recognized in the frequencies of transferrin alleles. In the whole population frequencies of transferrin alleles were found to be TfA = 0.089, TfB = 0.163, TfC = 0.232, TfD = 0.495 and TfE = 0.021. Transferrin system has shown an absence of genetic equilibrium among the analyzed herd (chi2 value = 51.31). In conclusion, there were polymorphism in Transferrin types and the presence of differences among the frequencies of the five alleles by categories could be a source of genetic variation in Garole sheep.

    Full Text Available The sheeps breeding is an old and traditional activity in Romania country. Depending on the number of sheeps and goats, Romania ranks in the fourth among E.U. countries. The research was conducted on three groups of sheeps, from same breed. All groups sheeps were feeding with the same amount of food, but the ratio structure was different, in the following scheme conformities: group I - has been used a fibrous ratio; group II – has been used a juicy ratio; group III – has been used a concentrate ratio. Also, in all the groups was recorded the milk production and the weight of lambs in the first month of the life. Based on research conducted, the fallowing conclusions were drawn: The highest milk production was produced by sheeps in group I and group II; The weight of lambs in the first month of life was also influenced by the mother sheeps ratio structure; The largest increase growth was made of lambs coming from a group III, and the smallest increase was made of lambs coming a group II. As a general conclusion, the best results are obtained when the mother sheeps are fed with concentrate ratio type and fibrous ratio type.

  17. A study of growth traits in goat breeds of northern areas of Pakistan

    International Nuclear Information System (INIS)

    Pakistan has 49.14 million goats. Goats are kept for milk and meat production and contribute significantly to the income of the rural farmers. Dairy goats are kept by the farmers belonging to poor socio-economic class of the society, mostly landless. Goat production is almost evenly distributed among all regions of Pakistan. The vast majority of small ruminant flock owners are small-scale farmers, sometimes landless. Mixed flocks are common, although separate flocks of sheep or goats can also be seen. The Northern Areas of Pakistan provide many chances for goat raising on pastures and goats are the main stay of the poorest segments of rural society. The data on goat breeds of Northern Areas is still lacking. The present study was planned to provide baseline information of growth traits of goat breeds of Northern Areas. Six goat breeds, found in the Northern Areas of Pakistan, Pameri, Gojali, Balti (pashmina bearing), Dareli, Jerakheil and Koh-e- Ghizer w ere studied for growth traits like birth weight, weaning weight, adult weight, body length, heart girth and height. The mean birth (males: 2.81 ± 0.111 females: 2.36 ± 0.777 kilograms), weaning (males: 13.14 ± females: 11.11 ± 0.779 kilograms) and adult (males: 70.79 C females: 46.11 ± 0.786 kilograms) weight was highest in Dareli followed by Jerakheil, Koh-e-Ghizer, Pameri, Balti and Gojali. Among the various breeds studied Jerakheil displayed higher body length (males: 85.93 ± 0.875 females: 75.48 ± 0.975 cm) followed by Daeli, Koh-e-Ghizer, Gojali, Pameri and Balti. Dareli was found the tallest breed (males: 85.41± 0.424 females: 74.13 ± 0.750 centimetres) and Pameri the shortest (males: 70.36 ± 0.710 females: 57.91 ± 0.342 centimetres). The mean heart girth was also highest in Dareli (males: 95.67 ± 2.00 females: 86.89 ± 0.475 centimetres) and lowest in Pameri (males: 70.42 ± 0.498 females: 65.32 ± 0.603 centimetres).

    The overall objective of this study was to calculate the amount of nitrogen (N) that cattle feed must contain in order to utilise the potential supply of utilisable crude protein at the duodenum provided by their energy intake without incurring a negative N balance, that is, without having to break down body protein. For this purpose, the literature was screened for measurements of net degradation and renal excretion of urea as well as N balances (N intake, faecal N and urinary N) in ruminants (cattle, sheep and goats) fed diets with varying N concentrations. Irreversible loss of N from the body urea pool increased with increasing N intake, but net degradation of urea as a proportion of irreversible loss decreased concurrently. Faecal N appeared not to be influenced by N intake and exceeded 11 g/kg dry matter intake (DMI) only in 7% of the data sets available. Urinary non-urea-N rarely exceeded 4 g/kg DMI and appeared independent of N intake. Urinary urea-N showed a clear dependence of N intake, and it is concluded that 1 g N/kg DMI is sufficient for compensating inevitable N losses in the form of urinary urea. In conclusion, ruminant rations should contain the following N concentrations (per kg DM) to account for obligatory losses: 11 g for compensating losses as faecal N, 4 g for compensating losses as urinary non-urea-N and 1 g for compensating inevitable losses as urinary urea-N. The derived recommendations should be helpful for limiting N excretion where this is desirable for ecological reasons. PMID:27216556

  19. Generation of five human lactoferrin transgenic cloned goats using fibroblast cells and their methylation status of putative differential methylation regions of IGF2R and H19 imprinted genes.

    Directory of Open Access Journals (Sweden)

    Li Meng

    Full Text Available BACKGROUND: Somatic cell nuclear transfer (SCNT is a promising technique to produce transgenic cloned mammalian, including transgenic goats which may produce Human Lactoferrin (hLF. However, success percentage of SCNT is low, because of gestational and neonatal failure of transgenic embryos. According to the studies on cattle and mice, DNA methylation of some imprinted genes, which plays a vital role in the reprogramming of embryo in NT maybe an underlying mechanism. METHODOLOGY/PRINCIPAL FINDINGS: Fibroblast cells were derived from the ear of a two-month-old goat. The vector expressing hLF was constructed and transfected into fibroblasts. G418 selection, EGFP expression, PCR, and cell cycle distribution were applied sequentially to select transgenic cells clones. After NT and embryo transfer, five transgenic cloned goats were obtained from 240 cloned transgenic embryos. These transgenic goats were identified by 8 microsatellites genotyping and southern blot. Of the five transgenic goats, 3 were lived after birth, while 2 were dead during gestation. We compared differential methylation regions (DMR pattern of two paternally imprinted genes (H19 and IGF2R of the ear tissues from the lived transgenic goats, dead transgenic goats, and control goats from natural reproduction. Hyper-methylation pattern appeared in cloned aborted goats, while methylation status was relatively normal in cloned lived goats compared with normal goats. CONCLUSIONS/SIGNIFICANCE: In this study, we generated five hLF transgenic cloned goats by SCNT. This is the first time the DNA methylation of lived and dead transgenic cloned goats was compared. The results demonstrated that the methylation status of DMRs of H19 and IGF2R were different in lived and dead transgenic goats and therefore this may be potentially used to assess the reprogramming status of transgenic cloned goats. Understanding the pattern of gene imprinting may be useful to improve cloning techniques in future.

  20. Clinical signs, treatment, and postmortem lesions in dairy goats with enterotoxemia: 13 cases (1979-1982).

    1992-01-15

    Enterotoxemia attributable to Clostridium perfringens type D in goats is difficult to diagnose because of a lack of specific clinical signs or postmortem lesions, on which to base the diagnosis. This report describes the clinical signs, postmortem lesions, and clinical responses to treatment and vaccination in 4 goat herds, in which a diagnosis of enterotoxemia was confirmed. Four clinical cases had the diagnosis confirmed on the basis of signs of diarrhea or sudden death and the isolation of C perfringens and epsilon toxin from the feces at the time of admission. The 10 necropsy cases were diagnosed on the basis of the isolation of C perfringens (not typed) or epsilon toxin from the intestinal contents of goats that died with clinical signs compatible with enterotoxemia and without lesions associated with a second serious disease. Enterocolitis was the most consistent lesion reported at necropsy in the 10 goats with enterotoxemia. Ovine enterotoxemia vaccines were of limited value in preventing enterotoxemia. These observations imply that naturally induced enterotoxemia in goats involves a different pathophysiologic mechanism than that associated with enterotoxemia in sheep. PMID:1559880
