    Domestic goats, Capra hircus, were intentionally introduced to numerous oceanic islands beginning in the sixteenth century. The remarkable ability of C. hircus to survive in a variety of conditions has enabled this animal to become feral and impact native ecosystems on islands throughout the world. Direct ecological impacts include consumption and trampling of native plants, leading to plant community modification and transformation of ecosystem structure. While the negative impacts of feral goats are well-known and effective management strategies have been developed to control this invasive species, large populations persist on many islands. This review summarizes the impacts of feral goats on Pacific island ecosystems, and the management strategies available to control this invasive species.

    The average number of available oocytes recovered per ovary collected during the breeding season in dairy goats was 5.5 (1815/330). 66.17% (1201/1815) of oocytes extruded the first polar body after maturation in vitro for 20 h. 75.44% (906/1201) of matured oocytes with membrane evagination around the MⅡchromosomes were enucleated. Ear skin fibroblast cells were derived from an adult female Jining Grey goat (C. hircus). The cells were cryopreserved in liquid nitrogen after passage 2. Thawed cells were further cultured for 3-6 passages and were subjected to serum starvation by 0.5% FBS for 2-10 d, then used as donor cells for nuclear transfer. 98.12% (889/906) of the enucleated oocytes were reconstructed by intracytoplasmic injection of karyoplast. The reconstructed embryos were activated by 5 μmol/L ionomycin for 4.5 min and further activated by culturing with 6-dimethylaminopurine (6-DMAP) for 3 h. After 36 h of culture in mCR1aaBF, 76.69% (645/841) of the cloned embryos cleaved. There were no significant differences in development in vitro between the cloned embryos derived from donor cells precooled at 4℃ for 24 h and nonprecooled donor cells. The cleavage rates, 4-cell development, and blastocyst development of reconstructed embryos were 72.48% (79/109), 53.16% (42/79), and 19.05% (8/42) in precooled group; 68.5% (211/308), 59.72% (126/211), and 17.46% (22/126) in nonprecooled group, respectively. Eighteen cloned 4-cell embryos derived from precooled donor cells were transferred and one cloned kid was born. Eighty-four cloned 4-cell embryos derived from nonprecooled donor cells were transferred and no offspring were produced. Of 18 cloned morale from nonprecooled donor cells transferred, one kid was born. The results of microsatellite DNA analyses indicated that the two cloned kids were from the same donor fibroblast cell line derived from an adult goat ear skin.

    Xinong Saanen dairy goat (Capra hircus), a breed distributed widely and adapted highly in China, has the characteristics of high milk production and high litter size. Our research revealed that the complete mitochondrial genome of Xinong Saanen dairy goat was 16,639 bp in length. The contents of A, C, G and T in the mitochondrial genome were 33.6%, 26.0%, 13.1% and 27.3%, respectively. It had a typical mitogenome structure, containing 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and 1 control region. Most of the PCGs have ATG initiation codons, whereas ND2, ND3 and ND5 start with ATA. These results provide essential information for phylogeographic history and population genetic structure, genetic diversity of domestic goats and mitochondrial genome editing based on the goat model.

    Full Text Available Very little is known about the spacing behaviour in social groups of domestic goats (Capra hircus in the farm environment. In this experiment, we studied interindividual distances, movement patterns and activity budgets in pregnant goats housed at three different densities. Norwegian dairy goats were kept in stable social groups of six animals throughout pregnancy at 1, 2 or 3 m2 per individual and their spacing behaviours (i.e., distance travelled, nearest and furthest neighbour distance and activity budgets (e.g., resting, feeding, social activities were monitored. Observations were made in the first, second and last thirds of pregnancy in the mornings, at noon and in the afternoons of each of these phases (4.5 hours per observation period. The findings show that goats held at animal densities of 2 and 3 m2 moved longer distances when they had more space per animal and kept larger nearest and furthest neighbour distances when compared to the 1 m2 per animal density. Less feeding activity was observed at the high animal density compared to the medium and low density treatments. The phase of gestation also had an impact on almost all behavioural variables. Closer to parturition, animals moved further distances and the increase in nearest and furthest neighbour distance was more pronounced at the lower animal densities. During the last period of gestation, goats spent less time feeding and more on resting, social behaviours and engaging in other various activities. Our data suggest that more space per goat is needed for goats closer to parturition than in the early gestation phase. We concluded that in goats spacing behaviour is density-dependent and changes with stages of pregnancy and activities. Finally, the lower density allowed animals to express individual preferences regarding spacing behaviour which is important in ensuring good welfare in a farming situation.

    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

    Full Text Available Cashmere goat (Capra hircus hair follicle development and cycling can be divided into three stages: anagen, catagen and telogen. To elucidate the genes involved in hair follicle development and cycling in cashmere goats, transcriptome profiling of skin was carried out by analysing samples from three hair follicle developmental stages using RNA-Seq. The RNA-Seq analysis generated 8487344, 8142514 and 7345335 clean reads in anagen, catagen and telogen stages, respectively, which provided abundant data for further analysis. A total of 1332 differentially expressed genes (DEGs were identified, providing evidence that the development of hair follicles among the three distinct stages changed considerably. A total of 683 genes with significant differential expression were detected between anagen and catagen, 530 DEGs were identified between anagen and telogen, and 119 DEGs were identified between catagen and telogen. A large number of DEGs were predominantly related to cellular process, cell & cell part, binding, biological regulation and metabolic process among the different stages of hair follicle development. In addition, the Wnt, Shh, TGF-β and Notch signaling pathways may be involved in hair follicle development and the identified DEGs may play important roles in these signaling pathways. These results will expand our understanding of the complex molecular mechanisms of hair follicle development and cycling in cashmere goats and provide a foundation for future studies.

    Lysosomal α-Mannosidase (LAM) belongs to the glycoside hydrolyzing enzymes family 38 and is involved in the biosynthesis and turnover of N-linked glycoproteins process. Locoweeds, which contain swainsonine (SW) that inhibits LAM, are the main poisoning plants in many regions of the world, and thereby resulting in animal poisoning or even death. Based on regions of protein sequence conservation between LAM from Bos taurus and Homo sapiens, we cloned cDNA encoding Capra hircus LAM (chLAM). Expression of cDNA in Pichia pastoris resulted in the secretion of aLAM activity into the culture medium. The recombinant chLAM was activated 1.6 and 1.2-fold with Zn(2+) and Ca(2+), respectively. By homology modeling, molecular docking and mutant analysis, we obtained the probable binding modes of SW at the allosteric sites of chLAM, and the potential mutant sites for the resistance to SW. Prediction of SW sensitivity to A28 W/G, D58 Y/G mutant chLAM is lower than wild type chLAM. The obtained results lead to a better understanding of not only interactions between substrate/SW and chLAM, but also of a potential strategy for a novel therapy for locoweed poisoning.

    Tyrosinase is the key regulatory enzyme of melanogenesis and plays a major role in mammal coat color. For the first time, we have sequenced and characterized the tyrosinase (TYR) of Jining Gray Goat (Capra hircus), which is the world-famous fur-bearing animal with its special color and pattern. The full-length cDNA was cloned by a reverse-transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA end (RACE) method. As a result, one 2131-bp nucleotide sequence representing the full-length cDNA of TYR was obtained. The entire open reading frame (ORF) of the TYR is 1593 bp and encodes for 530 amino acids, which is well conserved compared with TYR of various species with higher degree of sequence similarity with other mammalian (74-99 %) than amphibian, aves, and fishes (56-73 %). The deduced amino acids contained one signal peptide, one transmembrane domain, five N-linked glycosylation sites, and two copper binding sites. The result of real-time quantitative PCR showed that the expression level of TYR was the highest in the dark-gray goats and the lowest in the light-gray ones, while the goats of dark-gray individuals have more than 50 % black fiber and light-gray ones less than 30 %. During the whole life of Jining gray goat, TYR expression level changes with certain regularity and their coat color will change correspondingly by investigating the expression level in ten development stages. After comparing the result and the coat phenotype, we presume that it seems to have a positive relationship between the color depth of coat and the expression level of TYR. PMID:22407568

    The expression of six different aquaporins (AQP1, 2, 3, 4, 5 and 9), integral membrane water channels that facilitate bi-directional passive movement of water, was investigated by immunohistochemistry in the uterine tube of pre-pubertal and adult Saanen goats (Capra hircus), comparing the different phases of the oestrous cycle. Regional morphology and secretory processes were markedly different during the goat oestrous cycle. The tested AQP molecules showed different expression patterns in comparison with already studied species. AQP1-immunoreactivity was evidenced at the endothelium of blood vessels and in nerve fibres, regardless of the tubal tract and cycle period. AQP4-immunoreactivity was shown on the lateral plasmalemma in the basal third of the epithelial cells at infundibulum and ampulla level in the cycling goats, more evidently during follicular than during luteal phase. No AQP4-immunoreactivity was noticed at the level of the isthmus region, regardless of the cycle phase. AQP5-immunoreactivity, localized at the apical surface of epithelial cells, increased from pre-puberty to adulthood. Thereafter, AQP5-immunoreactivity was prominent during the follicular phase, when it strongly decorated the apical plasmalemma of all epithelial cells at ampullary level. During luteal phase, immunoreactivity was discontinuous, being weak to strong at the apex of the secretory cells protruding into the lumen. In the isthmus region, the strongest AQP5-immunoreactivity was seen during follicular phase, with a clear localization in the apical plasmalemma of all the epithelial cells and also on the lateral plasmalemma. AQP2, 3 and 9 were undetectable all along the goat uterine tube. Likely, a collaboration of different AQP molecules sustains the fluid production in the goat uterine tube. AQP1-mediated transudation from the blood capillaries, together with permeation of the epithelium by AQP4 in the basal rim of the epithelial cells and final intervening of apical AQP5, could

    Full Text Available In this study the heart, kidneys and adrenal glands of 36 teddy goats (Capra hircus of both sexes, divided in 3 age groups viz. kids (6-12 months, adults (13-21 months and old (22-24 months were collected after slaughter. Immediately after collection, absolute and relative weights, length, width, thickness, circumference and volume of all organs were recorded. Shape of the heart was cone like and the coronary groove was filled with fat. None of the anatomical parameters of the heart, kidneys and adrenal glands differed between male and female goats, except that absolute weight of the right kidney and volume of right and left kidneys were higher in males than in females (P<0.05. Absolute and relative weights of the heart, volume, length, circumference, right atrial wall thickness and right ventricle wall thickness were higher in old than in kids or adult animals (P<0.05. No difference was seen in various anatomical parameters between the right and the left kidneys. However, values of most of the anatomical parameters were higher in old than in kids or adult goats (P<0.05, except relative weight of the organ and thickness of medulla, which did not differ among animals of three age groups. For adrenals, the absolute weight and length of the left organ were higher than the right (P<0.05. Similarly, absolute weight, length and width were higher in old than in kids (P<0.05. It is conceivable from these findings that goat has a stable cardiovascular system. The development of heart, kidneys and adrenals showed an increase parallel to the advancing age to adjust with the increasing blood pressure due to physiological development process. Sex, however, played a secondary role.

Inner Mongolia Cashmere goats (Capra hircus have a double coat comprising the primary and secondary hair follicles, which have dramatically different sizes and textures. The Cashmere goat is rapidly becoming a potent model for hair follicle morphogenesis research. In this study, we established two dermal papilla cell lines during the anagen phase of the hair growth cycle from the primary and secondary hair follicles and clarified the similarities and differences in their morphology and growth characteristics. High-throughput transcriptome sequencing was used to identify gene expression differences between the two dermal papilla cell lines. Many of the differentially expressed genes are involved in vascularization, ECM-receptor interaction and Wnt/β-catenin/Lef1 signaling pathways, which intimately associated with hair follicle morphogenesis. These findings provide valuable information for research on postnatal morphogenesis of hair follicles.

    Objective: To determine the activity of superoxide dismutase (SOD) in the male and female haematophagous caprine worms, Haemonchus contortus infecting Capra hircus, and their E/S products and also to analyse the effect of Haemonchus infection on the level of host SOD. Methods: The SOD activity was analysed by using the pyrogallol autoxidation assay and non-denaturing polyacrylamide gel electrophoresis followed by specific enzyme staining by riboflavin-nitroblue tetrazolium method. Results: The adult females were found to have higher enzyme activity than the male worms. Appreciable amount of SOD activity was also detected in the worm culture medium and female worms secreted more SOD in comparison to the male parasites. The SOD activity was negatively correlated to the worm burden. Statistically significant decrease in SOD activity (P Conclusions:Haemonchus contortus is a key model parasite for drug and vaccine discovery. The presences of SOD activity in appreciable amount in the parasite as well as its E/S products indicate that it has a well-developed active antioxidant system to protect itself from the host immune attack. SOD could be the target for vaccine development which is the need of the hour as mass drug administration for parasite control has resulted in anthelmintic resistance across the globe and threatens the viability of sheep and goat industry in many regions of the world. The infection with Haemonchus causes a drastic reduction in SOD activity of the host tissue thus effecting its protective potential. One characteristic SOD band was found in the females which was not present in any other preparations and thus could be exploited for further studies on diagnostic/control measures.

    对生活于苏格兰西北部拉姆岛上的野化山羊(Capra hircus)种群在1981、 1982和2000年三年中的日活动节律进行了分析研究. 详细分析了两个主要气象因素(温度和降水)以及昼长季节变化对该种群动物的日活动节律的影响.研究结果表明, 拉姆岛上野化山羊的日取食活动时间百分比随月平均温度上升而显著下降, 但卧息活动时间百分比随月平均温度的上升而显著上升,而降水则对二者无显著影响.拉姆岛所在地区的昼长季节性变化明显,每年6、7月白昼时间最长,而12、1月最短. 由于受昼长季节变化影响,尽管该山羊种群的日取食活动时间百分比随季节变化而由夏季到冬季增加,但其真正用于取食活动的白昼时间由夏季到冬季反而减少.研究表明,白昼时间长短的季节变化是制约该山羊种群取食活动的一个重要因素,尤其是在食物匮乏而天气寒冷、阴湿的冬季.进而探讨了这种制约作用对其冬季取食量和冬季存活率的影响,以及对种群数量的调节意义.%Daytime activity budgets of feral goats (Capra hircus) were studied in 1981, 1982 and 2000 on the Isle of Rum, northwest Scotland. This paper analyzes the influence of key weather variables (temperature and rainfall) and seasonal variations in daylength on daytime activity budgets. This study showed that the percentage of daytime spent in feeding by feral goats on Rum Island decreased with average monthly temperature, while the percentage of daytime spent in lying increased and rainfall had no significant effects on the percentage daytime spent in feeding or lying. The daylength varied greatly from January to December with the longest daylength being in June and July, and the shortest one in December and January. The amount of daytime spent feeding decreased from summer to winter, although the percentage of daytime spent feeding increased greatly from summer to winter. The seasonal

    Congenital cardiac defects are anatomic conditions present at birth. Few references to such conditions in goats are available in the current scientific literature. This report describes, for the first time, a congenital cardiac disease clinically characterized by polypnea from birth and exercise intolerance in a 2-month-old pygmy goat. An atrioventricular dysplasia known as Ebstein's anomaly, an atrial septal defect, and a mild subaortic stenosis were ultrasonographically diagnosed.

    Full Text Available Foi realizado um estudo de casos de osteoporose em caprinos provenientes de uma propriedade na área de abrangência do LPV-UFSM, determinando a epidemiologia, o quadro clínico-patológico e discutindo os prováveis mecanismos patogenéticos. Cinco cabras, fêmeas, SRD, de seis meses a seis anos de idade foram afetadas. As cabras eram mantidas em campo nativo, sem suplementação com ração e sob superlotação. Os principais sinais clínicos foram emagrecimento, dificuldade de locomoção e permanência em decúbito por longos períodos. As principais alterações macroscópicas nos ossos examinados foram vistas nas superfícies de corte e caracterizavam-se por depleção do osso esponjoso (porosidade e redução acentuada da espessura do osso cortical. Havia também marcada atrofia serosa da gordura da medula óssea. Microscopicamente, nas regiões avaliadas (úmero proximal, rádio distal, fêmur distal, tíbia proximal e corpos das vértebras lombares foi observada redução moderada a acentuada do número e da espessura das trabéculas ósseas nas epífises e metáfises dos ossos longos e nos corpos vertebrais. Os achados clínico-patológicos indicaram que a osteoporose observada provavelmente foi causada pela desnutrição. As alterações ósseas (diminuição no número e na espessura das trabéculas do osso esponjoso sugerem que ambos os mecanismos, má formação óssea e reabsorção óssea aumentada, contribuíram para a ocorrência de osteoporose nos caprinos deste estudo.

  11. Phytohemagglutinin improves the development and ultrastructure of in vitro-cultured goat (Capra hircus) preantral follicles

    International Nuclear Information System (INIS)

    The objective this study was to determine the effect of phytohemagglutinin (PHA) on survival, growth and gene expression in caprine secondary follicles cultured in vitro. Secondary follicles (∼0.2 mm) were isolated from the cortex of caprine ovaries and cultured individually for 6 days in α-MEM+ supplemented with PHA (0, 1, 10, 50, 100, or 200 µg/mL). After 6 days of culture, follicle diameter and survival, antrum formation, ultrastructure and expression of mRNA for FSH receptors (FSH-R), proliferating cell nuclear antigen (PCNA), and neuronal nitric oxide synthase were determined. All treatments maintained follicular survival [α-MEM+ (94.59%); 1 µg/mL PHA (96.43%); 10 µg/mL PHA (84.85%); 50 µg/mL PHA (85.29%); 100 µg/mL PHA (88.57%), and 200 µg/mL PHA (87.50)], but the presence of 10 µg/mL PHA in the culture medium increased the antrum formation rate (21.21%) when compared with control (5.41%, P < 0.05) and ensured the maintenance of oocyte and granulosa cell ultrastructures after 6 days of culture. The expression of mRNA for FSH-R (2.7 ± 0.1) and PCNA (4.4 ± 0.2) was also significantly increased in follicles cultured with 10 µg/mL PHA in relation to those cultured in α-MEM+ (1.0 ± 0.1). In conclusion, supplementation of culture medium with 10 µg/mL PHA maintains the follicular viability and ultrastructure, and promotes the formation of antral cavity after 6 days of culture in vitro

    Full Text Available The study was conducted to evaluate the effects of romifidine alone (50 µg/kg and a combination of romifidine (50 µg/kg and ketamine (2.5 mg/kg after intrathecal administration in goats. Ten adult goats of either sex weighing between 15 and 20 kg were randomly placed in 2 groups (groups I and II. The agents were administered at the lumbosacral subarachnoid space. Clinico-physiological parameters such as analgesia, motor incoordination, sedation, salivation, heart rate, respiratory rate, arterial pressure, central venous pressure and rectal temperature were studied. Other haematobiochemical parameters monitored were packed cell volume, haemoglobin, plasma proteins, glucose, urea and creatinine. The onset of analgesia was faster in group II (35.5 ±6.25 s compared to that of group I (5.2 ±0.54 min. Analgesia of the tail, perineum, hind limbs, flank and thorax was mild to moderate in group I, but complete analgesia of tail, perineum and hind limbs was recorded in group II. Motor incoordination was mild in group I and severe in group II. Significant reduction in heart rate (more pronounced in group I and respiratory rate (more pronounced in group II, and a significant increase in central venous pressure were recorded in both groups. Mean arterial pressure was reduced in both groups, but more markedly in group I. Sedation, electro-cardiogram, rectal temperature and haemato-biochemical parameters did not show significant differences between the 2 groups. The results of this study indicated a possible synergistic analgesic interaction between intrathecally administered romifidine and ketamine, without causing any marked systemic effects in goats.

    To research the molecular characteristics, expression pattern and phylogeny of the Delta-like 1 homolog gene (Dlk1) in goats. Dlk1 transcripts were identified in the Jianyang Da'er goats by reverse-transcription polymerase chain reaction (RT-PCR). Phylogenetic trees were constructed by Bayesian inference and neighbor-joining methods. Quantitative real-time PCR (qPCR), western blotting and in situ hybridization were performed to analyze the expression pattern of Dlk1. Five alternatively transcripts were identified in different tissues and designated as Dlk1-AS1, 2, 3, 4 and 5. Compared with the normal transcript Dlk1-AS1, Dlk1-AS4 and Dlk1-AS5 retained the identical open reading frame (ORF) and encoded proteins with truncated epidermal-growth-factor like repeats of 121 and 83 amino acids, respectively. Using the Bayesian inference method, the consensus phylogenetic tree indicated that caprine Dlk1 had a closer relationship with bovine Dlk1 than with Dlk1 from pigs, humans and mice. qPCR revealed high expression levels of Dlk1 in the kidney (P < 0.01). However, mRNA and protein levels presented an inconsistent correlation, possibly because of post-transcriptional regulation. RNA in situ hybridization indicated that Dlk1 mRNA was localized in the interlobular bile duct and alongside the hepatocyte nuclei, in the epithelial cells of proximal and distal convoluted tubules and in the connective region between the mesothelium and myocardium in the heart. The Dlk1 gene in goats produces alternatively spliced transcripts, with specific expression and cellular localization patterns. These findings would lay the foundation for further study.

    Full Text Available The physiological effects on respiratory function of etorphine (M99, Logos Agvet (30 µg/kg administered intramuscularly were determined in boer goats. The goats were habituated to the experimental procedures so that respiratory function could be determined while the animals stood quietly at rest. This enabled the physiological changes induced by etorphine to be measured and compared with those obtained before administration of the immobilising drug. The effectiveness of diprenorphine (M5050, Logos Agvet (3 mg/1 mg etorphine as an antagonist of the physiological changes induced by the etorphine treatment was also determined. Etorphine depressed respiratory function, which resulted in a decrease in PaO2 and an increase in PaCO2. These changes were limited and occurred as a result of decreases in respiratory minute volume and alveolar minute ventilation caused by a decrease in respiratory rate. The physiological shunt fraction did not change significantly but there was a significant decrease in percentage physiological dead space ventilation. It was not possible to determine how effectively diprenorphine reversed the respiratory effects due to etorphine.

    In an experiment to examine the relationships between adrenals and reproductive cycle, 10 mg dexamethasone (a synthetic glucocorticoid) were injected intramuscularly twice daily for 10 d to four Black Bengal goats, beginning on Day 11 of the synchronized estrous cycle. The extended length of the sexual cycle was monitored by the clinical signs of anestrus. Laparotomy was performed to examine the status of the ovary of an 8, 9, 10 and 8 d extended cycle, respectively. The length of the next cycle was normal. Endogenous cortisol values were suppressed for 11, 13, 20 and 24 d, respectively. It is thought that dexamethasone caused prolonged luteal function either by the suppression of prostaglandin F(2)alpha synthesis or by the suppression of pituitary stimulation of follicular growth.

    Approximately 50 genes other than heat shock protein (HSP) expression changes during thermal stress. These genes like nitric oxide synthase (NOS) need proper attention and investigation to find out their possible role in the adaptation to thermal stress in animals. So, the present study was undertaken to demonstrate the expressions of inducible form type II NOS (iNOS), endothelial type III NOS (eNOS), constitutively expressed enzyme NOS (cNOS), HSP70, and HSP90 in peripheral blood mononuclear cells (PBMCs) during different seasons in Barbari goats. Real-time polymerase chain reaction, western blot, and immunocytochemistry were applied to investigate messenger RNA (mRNA) expression, protein expression, and immunolocalization of examined factors. The mRNA and protein expressions of iNOS, eNOS, cNOS, HSP70, and HSP90 were significantly higher ( P < 0.05) during peak summer, and iNOS and eNOS expressions were also observed to be significantly higher ( P < 0.05) during peak winter season as compared with moderate season. The iNOS, eNOS, cNOS, HSP70, and HSP90 were mainly localized in plasma membrane and cytoplasm of PBMCs. To conclude, data generated in the present study indicate the possible involvement of the NOS family genes in amelioration of thermal stress so as to maintain cellular integrity and homeostasis in goats.

    Maternal behavior in the goat appears at the time of parturition, partly under the activating influence of vaginocervical stimulation. Mothers actively lick their neonate and rapidly establish a selective bond with their kid through olfactory recognition. They also develop visual and acoustic recognition of the kid within 4 h following birth. Acoustic recognition is present at 48 h. The establishment of maternal recognition can be impaired by underfeeding during the second half of pregnancy. There is no indication that the mechanisms controlling the onset of maternal behavior and bonding are different from those reported in sheep, despite the fact that lambs start to follow their mother within a few hours after birth and kids hide for about a week. During lactation, the cues provided by the kid are necessary for the maintenance of maternal responsiveness, but suckling itself does not appear of primary importance. The presence of the kid also modulates the hormonal response to udder stimulation and influences recovery of postpartum sexual activity when kidding (i.e. birthing) takes place in autumn. Finally, the rapid establishment of mutual attachment between mother goats (does) and their kids offers the possibility to investigate an aspect of mother-young affiliation that is not present in many laboratory species.

    Full Text Available An experiment was performed to synchronize estrus in goats by locally prepared progesterone-impregnated sponges and to determine the time of onset and duration of estrus alongwith subsequent fertility rate. The study was conducted from May to December, 2007 at NIAB (Nuclear Institute for Agriculture and Biology, Faisalabad. Polyurethane sponges were prepared with medroxyprogesterone acetate (MAP: 60 mg and inserted intra-vaginally in a lot of 8 female postpartum goats (Beetal x Dwarf. Two goats were kept as control and were treated with sponges without MAP. Sponges were removed on 17th day of insertion and goats were examined for the signs of estrus at 6 h intervals. A buck was introduced in the herd for breeding, one day after removal of sponges. Estrus was further confirmed by determining serum estradiol levels using radioimmunoassay (RIA. All the experimental goats exhibited estrus within 21-100 h of removal of sponges, whereas one control animal also showed estrus. The average time from sponge withdrawal to the onset of estrus was 65.4 ± 24.0 h and duration of estrus was 29.8 ± 6.7 hours in experimental group. The control animal showed estrus after 22.0 h of sponge removal with estrus duration of 36 h. Estradiol concentrations in experimental lot were in the range of 2.2-15.0 pg/ml during estrus. Animals were observed for reversal towards estrus after 21 days. Only one experimental animal exhibited 2nd estrus. Pregnancy was confirmed by ultrasound after 60 days of sponge removal. The gestation period of 150.4 ± 3.4 days, a litter size of 1.3 ± 0.5 and a fertility rate of 87.5% were observed in the experimental lot. The control doe produced a male kid after 150.0 days of gestation. It is evident from this experiment that estrus can be synchronized in goats (Beetal x Dwarf by locally prepared progesterone sponges with good fertility rate.

    The objective this study was to determine the effect of phytohemagglutinin (PHA) on survival, growth and gene expression in caprine secondary follicles cultured in vitro. Secondary follicles (∼0.2 mm) were isolated from the cortex of caprine ovaries and cultured individually for 6 days in α-MEM{sup +} supplemented with PHA (0, 1, 10, 50, 100, or 200 µg/mL). After 6 days of culture, follicle diameter and survival, antrum formation, ultrastructure and expression of mRNA for FSH receptors (FSH-R), proliferating cell nuclear antigen (PCNA), and neuronal nitric oxide synthase were determined. All treatments maintained follicular survival [α-MEM{sup +} (94.59%); 1 µg/mL PHA (96.43%); 10 µg/mL PHA (84.85%); 50 µg/mL PHA (85.29%); 100 µg/mL PHA (88.57%), and 200 µg/mL PHA (87.50)], but the presence of 10 µg/mL PHA in the culture medium increased the antrum formation rate (21.21%) when compared with control (5.41%, P < 0.05) and ensured the maintenance of oocyte and granulosa cell ultrastructures after 6 days of culture. The expression of mRNA for FSH-R (2.7 ± 0.1) and PCNA (4.4 ± 0.2) was also significantly increased in follicles cultured with 10 µg/mL PHA in relation to those cultured in α-MEM{sup +} (1.0 ± 0.1). In conclusion, supplementation of culture medium with 10 µg/mL PHA maintains the follicular viability and ultrastructure, and promotes the formation of antral cavity after 6 days of culture in vitro.

    Aldoketoreductase 1B5 (AKR1B5), a member of the Aldoketoreductase family, is involved in the production of Prostaglandin F2α (PGF2α) as one of vital prostaglandin F synthase (PGFS). PGs (Prostaglandins) play a crucial role in female reproductive system. In the present study, we cloned and characterized the full-length open reading frame of AKR1B5 gene in Black Bengal (BB) goat. The complete coding sequence of AKR1B5 comprises an entire open reading frame of 951 bp, encoding 316 amino acid (AA) residues. BB AKR1B5 showed >82.9% identity with that of cattle, rabbit, human, and rat at nucleotide and amino acid levels, respectively. Further, a systematic study of AKR1B5 sequence evolution was also conducted using Phylogenetic Analysis by Maximum Likelihood (PAML), entropy plot, and Blossum 62 in a phylogenetic context. Analysis of nonsynonymous to synonymous nucleotide substitution rate ratios (Ka/Ks) revealed that negative selection may have been operating on this gene during evolution in goat, cattle, rabbit, human, and rat, which showed its conservation across species. Further, expression of AKR1B5 was determined by quantitative real-time PCR in goat endometrial tissues at different stages of the estrous cycle and early pregnancy. Our results indicated its high expression at luteolytic phase (stage III; day 16-21) during the estrous cycle. However, during early (day ∼30-40) pregnancy the expression was highest as compared to estrous cycle. PMID:25153450

    Full Text Available Prenatal stress (stress experienced by a pregnant mother and its effects on offspring have been comprehensively studied but relatively little research has been done on how prenatal social stress affects farm animals such as goats. Here, we use the operational description of 'stress' as "physical or perceived threats to homeostasis." The aim of this study was to investigate the prenatal effects of different herd densities on the fear responses and sociality of goat kids. Pregnant Norwegian dairy goats were exposed to high, medium or low prenatal animal density treatments throughout gestation (1.0, 2.0 or 3.0 m2 per animal, respectively. One kid per litter was subjected to two behavioral tests at 5 weeks of age. The 'social test' was applied to assess the fear responses, sociality and social recognition skills when presented with a familiar and unfamiliar kid and the 'separation test' assessed the behavioral coping skills when isolated. The results indicate goat kids from the highest prenatal density of 1.0 m2 were more fearful than the kids from the lower prenatal densities (i.e. made more escape attempts (separation test: P < 0.001 and vocalizations (social test: P < 0.001; separation test: P < 0.001. This effect was more pronounced in females than males in the high density (vocalizations; social test: P < 0.001; separation test: P  =  0.001 and females were generally more social than males. However, goat kids did not differentiate between a familiar and an unfamiliar kid at 5 weeks of age and sociality was not affected by the prenatal density treatment. We conclude that high animal densities during pregnancy in goats produce offspring that have a higher level of fear, particularly in females. Behavioral changes in offspring that occur as an effect of prenatal stress are of high importance as many of the females are recruited to the breeding stock of dairy goats.

    It has been shown that mice, particularly the BALB/c ones, are susceptible to infection by some of the apicomplexan parasites. To compare the susceptibility of the inbred BALB/c, outbred BALB/c and C57 BL/6 to Besnoitia caprae inoculation and to determine LD50, 30 male inbred BALB/c, 30 outbred BALB/c and 30 C57 BL/6 mice were assigned into 18 groups of 5 mice. Each group was inoculated intraperitoneally with 12.5 × 10(3), 25 × 10(3), 5 × 10(4), 1 × 10(5), 2 × 10(5) tachyzoites and a control inoculum of DMEM, respectively. The inbred BALB/c was found the most susceptible strain among the experienced mice strains so the LD50 per inbred BALB/c mouse was calculated as 12.5 × 10(3.6) tachyzoites while the LD50 for the outbred BALB/c and C57 BL/6 was 25 × 10(3.4) and 5 × 10(4) tachyzoites per mouse, respectively. To investigate the impact of different routes of inoculation in the most susceptible mice strain, another seventy five male inbred BALB/c mice were inoculated with 2 × 10(5) tachyzoites of B. caprae via various inoculation routes including: subcutaneous, intramuscular, intraperitoneal, infraorbital and oral. All the mice in the oral and infraorbital groups survived for 60 days, whereas the IM group showed quicker death and more severe pathologic lesions, which was then followed by SC and IP groups. Therefore, BALB/c mouse is a proper laboratory model and IM inoculation is an ideal method in besnoitiosis induction and a candidate in treatment, prevention and testing the efficacy of vaccines for besnoitiosis.

  19. CAPRA physics and the CIRANO experimental programme

    International Nuclear Information System (INIS)

    The burning of plutonium and higher actinides is being effectively implemented in the French nuclear programme. The reasons for doing so are fairly straightforward: - to maximize energy production by utilizing the large quantities of energy stored in reprocessed plutonium, - to alleviate the environmental impact of the nuclear industry by reducing potentially toxic transuranic material stockpiles. Reduction of Pu stockpiles can be achieved by multiple recycling in LWR MOX fuels. However, numerous studies have already demonstrated that the degraded Pu isotopics of multi-recycled fuel make it difficult to consider more than two or three effective recycling steps in LWR's. On the other hand, ultimate disposition of degraded Pu can be performed in fast reactors, whose hard neutron spectrum permits fissioning of higher actinides. Consequently, various efforts at CEA have been undertaken to understand and optimize Pu burning capabilities in fast reactors: - studies have been performed to optimize the design of fast reactor cores for burning plutonium while retaining acceptable safety characteristics, - industrial scale demonstration of several options of the CAPRA programme (Accrued Consumption of Plutonium in Fast Reactors) is planned in the PHENIX and SUPERPHENIX reactors, - the development of state of the art neutronics codes and associated nuclear data libraries, started almost ten years ago, should soon come to fruition and allow accurate predictions of Pu-burning core neutronics, - experimental data are needed to support the physical validation of these codes and their associated libraries.

    Besnoitia caprae is a tissue cyst-forming protozoan that infects goats and has considerable economic importance in certain regions of Asia and Africa. Murine macrophage J774 cell line was inoculated with tachyzoites of Besnoitia caprae (BC-Pars isolate) collected from mice. A significant growth of tachyzoites was observed in J774. Mice were inoculated with tachyzoites harvested from J774 cell culture. Skin samples from the mice infected with tachyzoites of BC-Pars were PCR positive. One mouse showed alopecia and skin lesions on 45 DPI. Dermal lesions started from around right eye and gradually developed more and more. After euthanasia on 60 DPI, histopathological evaluation of skins around the eye showed necrosis of the epidermis and follicular adnexa with chronic inflammatory cell infiltration. Histopathological sections of their skin showed the presence of necrosis and mononuclear cell infiltration. To the authors' knowledge, this is the first report of successful production of Besnoitia caprae tachyzoites was achieved in vitro by suspension culture technique. Another interesting finding is the report of the alopecia and skin lesions around the eye in mouse that quite similar to lesions of goats due to infection of Besnoitia caprae. PMID:26688623

    Seasonal weight loss (SWL) is the most important limitation to animal production in the Tropical and Mediterranean regions, conditioning producer's incomes and the nutritional status of rural communities. It is of importance to produce strategies to oppose adverse effects of SWL. Breeds that have evolved in harsh climates have acquired tolerance to SWL through selection. Most of the factors determining such ability are related to changes in biochemical pathways as affected by SWL. In this study, a gel based proteomics strategy (BN: Blue-Native Page and 2DE: Two-dimensional gel electrophoresis) was used to characterize the mitochondrial proteome of the secretory tissue of the goat mammary gland. In addition, we have conducted an investigation of the effects of weight loss in two goat breeds with different levels of adaptation to nutritional stress: Majorera (tolerant) and Palmera (susceptible). The study used Majorera and Palmera dairy goats, divided in 4 sets, 2 for each breed: underfed group fed on wheat straw (restricted diet, so their body weight would be 15-20% reduced by the end of experiment), and a control group fed with an energy-balanced diet. At the end of the experimental period (22 days), mammary gland biopsies were obtained for all experimental groups. The proteomic analysis of the mitochondria enabled the resolution of a total of 277 proteins, and 148 (53%) were identified by MALDI-TOF/TOF mass spectrometry. Some of the proteins were identified as subunits of the glutamate dehydrogenase complex and the respiratory complexes I, II, IV, V from mitochondria, as well as numerous other proteins with functions in: metabolism, development, localization, cellular organization and biogenesis, biological regulation, response to stimulus, among others, that were mapped in both BN and 2DE gels. The comparative proteomics analysis enabled the identification of several proteins: NADH-ubiquinone oxidoreductase 75 kDa subunit and lamin B1 mitochondrial (up-regulated in the Palmera breed), Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-2 (up-regulated in the Majorera breed) and cytochrome b-c1 complex subunit 1, mitochondrial and Chain D, Bovine F1-C8 Sub-Complex Of Atp Synthase (down-regulated in the Majorera breed) as a consequence of weight loss.

    Full Text Available Seasonal weight loss (SWL is the most important limitation to animal production in the Tropical and Mediterranean regions, conditioning producer's incomes and the nutritional status of rural communities. It is of importance to produce strategies to oppose adverse effects of SWL. Breeds that have evolved in harsh climates have acquired tolerance to SWL through selection. Most of the factors determining such ability are related to changes in biochemical pathways as affected by SWL. In this study, a gel based proteomics strategy (BN: Blue-Native Page and 2DE: Two-dimensional gel electrophoresis was used to characterize the mitochondrial proteome of the secretory tissue of the goat mammary gland. In addition, we have conducted an investigation of the effects of weight loss in two goat breeds with different levels of adaptation to nutritional stress: Majorera (tolerant and Palmera (susceptible. The study used Majorera and Palmera dairy goats, divided in 4 sets, 2 for each breed: underfed group fed on wheat straw (restricted diet, so their body weight would be 15-20% reduced by the end of experiment, and a control group fed with an energy-balanced diet. At the end of the experimental period (22 days, mammary gland biopsies were obtained for all experimental groups. The proteomic analysis of the mitochondria enabled the resolution of a total of 277 proteins, and 148 (53% were identified by MALDI-TOF/TOF mass spectrometry. Some of the proteins were identified as subunits of the glutamate dehydrogenase complex and the respiratory complexes I, II, IV, V from mitochondria, as well as numerous other proteins with functions in: metabolism, development, localization, cellular organization and biogenesis, biological regulation, response to stimulus, among others, that were mapped in both BN and 2DE gels. The comparative proteomics analysis enabled the identification of several proteins: NADH-ubiquinone oxidoreductase 75 kDa subunit and lamin B1 mitochondrial (up-regulated in the Palmera breed, Guanine nucleotide-binding protein G(I/G(S/G(T subunit beta-2 (up-regulated in the Majorera breed and cytochrome b-c1 complex subunit 1, mitochondrial and Chain D, Bovine F1-C8 Sub-Complex Of Atp Synthase (down-regulated in the Majorera breed as a consequence of weight loss.

    Goat production in Ethiopia is constrained by various bottlenecks and low genetic performance of local breeds is among them. Southern Agricultural Research Institute had introduced Boer goats, for crossing, evaluate and distribute to users. This research was conducted to assess the survivability and productive and reproductive performance of Boers and its crosses, on animals managed in on-station, Jinka Research Center and Key-afer Goat Research Station from January 2011 to March 2014. The diseases affecting the imported flock were heart water, pyogenic infections/caseous lymphadenitis, and wart/orf diseases with crude mortality rate of 47.6% and case fatality rates of 40.7, 2.4, and 4.7%, respectively. Heart water was responsible for 85% of the overall deaths. The twining percentage of Boer goats was found to be 36.3%, which was by far superior to that of Woito-guji breeds. The mortality rate in 50% crosses was found to be 35.2%; 54.5 and 20.6% in Jinka and Key-afer, respectively. The survival rate of 50% cross kids was found to be associated with birth weight and location. The average birth weight and 1 month weight of 75% crosses was found to be 3.25 ± 0.43 and 7.12 ± 1.57 kg, respectively. The 75% crosses survival rate up to weaning was found to be 100%. Despite improvement in productive and reproductive performance through increased exotic blood level, the survivability was strangely questioned for pure and higher blood levels in South Omo Zone. Pure Boer and 75% crosses could better adapt and perform in intensive and semi-intensive production systems. Small holder and pastoral livestock production systems, like South Omo Zone area, should focus on managing 50 % cross sires and rearing 25% crosses for market. PMID:26888205

    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.

    Full Text Available Dez caprinos foram vacinados com toxóide a 3%, outros dez com uma bacterina e mais dois grupos-controle de cinco animais cada, submetidos à inoculação de infusão de cérebro e coração e solução salina, respectivamente. Todos os animais foram examinados e avaliados com um teste de pele. Tanto o toxóide quanto a bacterina foram produzidos a partir de amostra de Corynebacterium pseudotuberculosis. Todos os caprinos foram desafiados com C. pseudotuberculosis, trinta dias após as vacinações. Nenhuma das vacinas induziu reação de hipersensibilidade na pele dos caprinos antes do desafio. Após o desafio, todos os animais desenvolveram reações mensuráveis na primeira, quinta e décima semana em resposta ao teste de pele. Os diâmetros da reação dérmica aumentaram do décimo dia à quinta semana após o desafio. As medidas alcançaram tamanho maior na décima semana. O resultado deste estudo indica que antígeno específico do C. pseudotuberculosis pode ser utilizado em caprinos no diagnóstico da linfadenite caseosa como teste de pele ou como instrumento experimental para monitorar o desenvolvimento da doença.

    Full Text Available Um surto de intoxicação espontânea por Portulaca elatior foi diagnosticado no município de Aroeiras, Paraíba, na época das chuvas. Entre os meses de fevereiro e abril, em um rebanho de 316 caprinos, 16 adoeceram, sendo 15 de um lote de 16 caprinos que tinham sido introduzidos recentemente na fazenda e um animal do rebanho já existente na fazenda. Os caprinos apresentaram intensa salivação, relutância em se movimentar, tremores de lábios, marcha incoordenada, diarreia, timpanismo, dor abdominal, gemidos, desidratação e berros constantes. A evolução da enfermidade variou de 2 a 48 horas; 13 caprinos morreram e três se recuperaram. As lesões macroscópicas caracterizavam-se por mucosa ruminal e do retículo avermelhadas, serosa do rúmen hemorrágica, mucosa abomasal avermelhada com áreas ulceradas e mucosa do intestino delgado com equimoses. No exame histopatológico observou-se degeneração e necrose das células epiteliais dos pré-estômagos com formação de vesículas e infiltrado inflamatório neutrofílico. Suspeita de ter causado o surto, Portulaca elatior foi administrada a três caprinos nas doses de 40, 20 e 10 gramas de planta fresca por kg de peso animal (g/kg. Esses caprinos apresentaram sinais semelhantes aos casos espontâneos. Os animais que ingeriram 20 e 40g/kg morreram e o que ingeriu 10g/kg se recuperou. Microscopicamente foram observadas lesões do sistema digestivo semelhantes às dos casos espontâneos. A reprodução experimental da intoxicação, com sinais clínicos e lesões histológicas semelhantes às dos casos espontâneos, comprova que a doença foi causada por Portulaca elatior. P. elatior apresentou níveis de oxalatos de 6,37% e outra planta, identificada como Blutaparon vermiculare e que ocorria em grande quantidade nas pastagens, apresentou níveis de oxalatos de 5,29%.

    International Nuclear Information System (INIS)

    Within the framework of the CAPRA programme, the potential of fast reactors for burning plutonium and minor actinides (Np, Am) is examined. The programme focuses on the development of an oxide reference core, but additional studies are carried out for design of advanced uranium-free cores. For reasons of reversibility, the CAPRA core should be of the size of the EFR (European Fast Reactor) core (1300 MWe), so that it might be integrated into an EFR facility. Reversibility in this context means that the design should permit as an alternative application installation of a CAPRA core designed for burning plutonium and minor actinides into the EFR facility, which is a breeding reactor, without need for modification of the EFR plant design.

    Full Text Available Entre os anos de 2007 e 2009 ocorreu uma doença nefrotóxica de evolução subaguda com alta mortandade em caprinos em uma propriedade no município de Itaguaí, estado do Rio de Janeiro. Levantou-se a suspeita de que Metternichia princeps, planta pertencente à família Solanaceae, seria a causa. Através de experimentação em caprinos o quadro clínico-patológico de intoxicação por esta planta e a dose letal foram estabelecidos. Na experimentação foram utilizados 12 caprinos de diferentes raças, de ambos os sexos, jovens a adultos, com pesos acima de 15 kg. Os animais que receberam as doses de 30g/kg em 5 dias, 15g/kg em 3 dias, doses únicas de 10g/kg e de 5g/kg, morreram. Dos três animais que receberam as doses únicas de 2,5g/kg, dois morreram e um não apresentou sinais clínicos e o animal que recebeu a dose única de 1,25g/kg, também não apresentou sinais clínicos. O início dos sinais clínicos após a administração da planta variou entre 7h e 46h45min. A evolução variou entre 3h6min e 126h40min. Os primeiros sinais clínicos apresentados foram inapetência, adipsia, apatia e relutância ao movimento. Em seguida os animais entravam em decúbito esternal e ao serem colocados em estação, mantinham os membros anteriores flexionados, apoiavam apenas os posteriores no chão até evoluírem para flexão dos quatro membros e seguia-se o decúbito lateral. À necropsia destacaram-se o edema de tecido adiposo perirrenal, rins pálidos e, ao corte, com estriação esbranquiçada desde o córtex até a região medular. À histopatologia foi verificada acentuada necrose coagulativa das células epiteliais dos túbulos uriníferos. Comparativamente aos casos naturais, os caprinos intoxicados experimentalmente por M. princeps apresentaram quadro clínico-patológico semelhante. Desta maneira foi comprovado que Metternichia princeps é responsável pela doença nefrotóxica em caprinos no Rio de Janeiro; a menor dose que causou a

    Full Text Available O controle do parasitismo por nematódeos gastrintestinais é feito basicamente com a utilização de anti-helmínticos. Falhas no controle são o primeiro sinal do aparecimento de resistência anti-helmíntica. A real situação da prevalência da resistência anti-helmíntica, em fazendas comerciais de criação de ovinos e caprinos no Brasil, é desconhecida. Esse experimento teve como objetivo, estimar a ocorrência de resistência ao oxfendazol, levamisol e ivermectina em propriedades comerciais de criação de ovinos e caprinos, na região do médio e baixo Jaguaribe, através do teste de redução na contagem de ovos nas fezes acompanhados de coproculturas. O trabalho foi realizado em 25 criações, sendo 16 de ovinos, 7 de caprinos e uma de ovinos e caprinos. Os dados obtidos foram analisados pelo programa estatístico RESO (1989. A prevalência de nematódeos resistentes ao oxfendazol, levamisol e ivermectina em ovinos foi de 88%, 41% e 59%, e em caprinos de 87,5%, 75% e 37,5%, respectivamente. Observou-se que o gênero Haemonchus foi o mais prevalente na população resistente a todos os anti-helmínticos, tanto em ovinos quanto em caprinos, seguido de Trichostrongylus e Oesophagostomum.

    Full Text Available Abstract Reference values for hematochemical parameters in wild animals are difficult to obtain, because of the effects of capture stress or of the drugs used for chemical restraint. To establish reference values for Capra ibex, we examined 30 females culled monthly from January to May 1991 in the Grisons (CH. The following serum variables were studied: cortisol, non esterified fatty acids (NEFA, glucose, triglycerides, cholesterol, total protein, calcium, inorganic phosphate. Values were compared with those of animals culled in the same period of 1990. The only significant differences were in serum cortisol and triglycerides, which were higher in 1991, when climatic conditions were less favourable. Serum NEFA were positively correlated with the animal's level of alertness. Most of the values of the serum parameters were within the range of those of the domestic goat.

  15. Fuel R+D in the context of CAPRA and SPIN

    International Nuclear Information System (INIS)

    After a short introduction giving a general view of the fuel element designs considered for CAPRI (consumption of Pu) and SPIN (Incineration of minor actinides), this paper will be focused on the R+D devoted to fabrication aspects and basic (physical, thermochemical and mechanical) properties of these fuels. Available results and future program covering this objective will be described. On the one hand, fuel element designs are based on 'classical' UPuO2 fuel elements. These designs include high Pu content (up to 45%) for CAPRA and/or additions of small quantities of minor actinides as Neptunium for SPIN. Fabrication of such fuel pins, dedicated to the experimental irradiation programme in support, does not reveal any major problem. In addition to the demonstration of high burn-up behaviour of such pins, future R+D program is focused on optimisation of fuel fabrication (Pu homogeneity for example) and characterization measurements. On the other hand, 'advanced' fuel designs (Pu without U for CAPRA or minor actinides targets as Americium without Pu and U for SPIN) have been considered. For such elements, many design options, potentially interesting, exist and have to be tested; so, very extensive R+D programs are necessary to investigate, in a first stage, fabrication and basic properties. First results and future program concerning Pu and Am new compounds (as nitride), inert matrices and modification of pin design will be commented. In conclusion, the need of an international cooperation to perform such large programs will be underlined. (author) 6 figs., 14 refs

Para isso, realizou-se o acompanhamento da epidemiologia da doença em sete municípios do semiárido pernambucano. Três caprinos espontaneamente intoxicados foram examinados e, em seguida eutanasiados e necropsiados (Grupo I. Para reproduzir experimentalmente a doença, as folhas secas de I. verbascoidea contendo 0,02% de swainsonina, foram fornecidas na dose de 4g/kg (0,8mg de swainsonina/kg a dois grupos de três animais. Os caprinos do Grupo II receberam a planta diariamente por 40 dias e foram eutanasiados no 41º dia de experimento. Os caprinos do Grupo III receberam a planta diariamente por 55 dias e foram eutanasiados no 120º dia de experimento. Outros três caprinos constituíram o grupo controle (Grupo IV. Nos grupos experimentais, as lesões encefálicas foram avaliadas por histopatologia e adicionalmente avaliaram-se as lesões cerebelares por morfometria, mediante mensuração da espessura da camada molecular, do número de neurônios de Purkinje e da área dos corpos celulares dessas células. Os principais sinais clínicos e lesões microscópicas foram semelhantes aos previamente reportados em animais intoxicados por plantas que contem swainsonina. Nos caprinos do GII e GIII, os primeiros sinais clínicos foram observados entre o 22º e 29º dia de experimento; clinicamente a doença desenvolvida por esses animais foi semelhante aos casos espontâneos. Nenhum dos caprinos do GIII se recuperou dos sinais neurológicos. Esse resultado evidencia que o consumo da planta por 26-28 dias após a observação dos primeiros sinais clínicos é suficiente para provocar lesões irreversíveis. Pela análise morfométrica, a camada molecular do cerebelo dos caprinos do Grupo I e III eram mais delgadas que

Ninety adult animals naturally infected were grouped according to the total egg count per feces gram (EPG: group I from zero to 500 EPG, group II from 501 to 2000 and group III above 2000. The parameters studied were serum total protein (STP, evaluated by biuret method; globulin (Glob, calculated by the difference between STP and serum albumin; gammaglobulin (Gglob, estimated throughout electrophoresis; immunoglobulin (Ig, estimated by turbidometry test with ZnSO4 and absolute lymphocyte count (Lymp / ml. It was found statistically decrease in three parameters (STP, Ig and Lymp / ml for group III. For Glob and Gglob, the decrease found was not statistically significant. These results show a depressor effect of nematode infection on humoral immune system. The intense dispersion of Glob and Gglob data can explain the not significant decrease found in those parameters. It was concluded that goats with intense nematode infection (above 2000 EPG can show immunedepression, with impairment of lymphocyte count and serum antibody level.O objetivo deste trabalho foi estudar a resposta imunológica em caprinos com vários graus de verminose gastrintestinal.

    Reproduction is a key factor for the successful establishment and spread of introduced species. Oxalis pes-caprae is a tristylous species with a self- and morph-incompatibility sexual system that, in the invaded range of the western Mediterranean Basin, has been found to reproduce asexually because only the pentaploid, short-styled morph (5x S-morph) was introduced. The objective of this study was to test the ability of the 5x S-morph of O. pes-caprae to produce viable offspring in the absence of compatible mates, exploring the hypothesis that new morphs could have emerged by sexual reproduction events of the initially introduced morph. Pollen germination, pollen tube development, fruit and seed production, seed germination and offspring ploidy levels were analysed after controlled hand-pollinations to assess self- and morph-incompatibility and production of viable gametes by the 5x S-morph. The self-incompatibility system is still operating, but a partial breakdown in the morph-incompatibility system combined with the production of viable gametes was observed, allowing sexual reproduction of the 5x S-morph in the invaded range. The ability of the 5x S-morph to reproduce sexually may have major consequences for the dynamics of invasive populations of O. pes-caprae and could be one of the factors involved in the occurrence of new floral morphs in this invaded range.

    Testes mass is a key factor in male reproductive success and is potentially exposed to so-called 'parasitic castration'. This is the result of the direct destruction or alteration of reproductive cell lineages (parasitic castration sensu stricto), or the indirect detrimental effects - for example, via body condition - on the ability of progenitors to produce or rear offspring (parasitic castration sensu lato). There are enormous gaps in our knowledge on the effects of parasites on the testes of wild mammals and in an attempt to rectify this dearth of data we examined the relationship between the skin parasite Sarcoptes scabiei and testes mass in Iberian ibex Capra pyrenaica. We considered data from 222 males that were culled in the population from the Sierra Nevada in Spain. Our results provide evidence that sarcoptic mange is associated with reduced size-corrected testes mass in Iberian ibex which supports the hypothesis that parasitism is a determining factor in gonad plasticity in male mammals. We discuss several hypothetical causes of this relationship and highlight the need to deepen the sub-lethal effects of pathogens if we are to accurately understand their modulator effects on host population dynamics.

    Full Text Available The aim of this study was to determine whether goats could be averted from consuming Mascagnia rigida, a toxic plant found in the semiarid region of northeastern Brazil. Fourteen male goats not previously familiarized to M. rigida were randomly allocated to two treatment groups: control (treated with 5.5mL water orally by a drenching gun and lithium group (treated with 100mg LiCl/kg body weight orally by a drenching gun. For conditioning, goats were allowed to feed on M. rigida leaves for 15 min, followed by LiCl or water administration. The time spent on eating M. rigida leaves was measured. The conditioning was repeated daily until the LiCl-treated goats stopped eating M. rigida. On the 10th, 17th, and 24th day after conditioning, extinction trials of the M. rigida aversion were performed in goats by using single-choice tests. There was no difference between the two treatment groups with respect to the consumption of M. rigida on the first day of aversion conditioning, however, controls ingested increasing amounts of the plant on consecutive conditioning days. On the second day, five out of the seven goats in the lithium group did not eat the leaves, but on the third day, all the goats in the lithium group did not ingest M. rigida. This aversion persisted throughout all evaluated days. This indicates that goats can be easily conditioned by using lithium chloride to avoid eating M. rigida temporarily.O objetivo do presente estudo foi determinar se os caprinos podem desenvolver aversão ao consumo de Mascagnia rigida, uma planta tóxica encontrada na região semi-árida do nordeste brasileiro.

    Full Text Available Palicourea marcgravii é considerada a principal planta tóxica de interesse pecuário no Brasil, porém, até o momento, é conhecido apenas o quadro agudo da intoxicação. Esse estudo avaliou as alterações clínico-patológicas de 10 caprinos cronicamente intoxicados por P. marcgravii. Os animais receberam, diariamente, 0,2g/kg de peso corporal da planta fresca por 6 a 38 dias. Os caprinos apresentaram como principais sinais clínicos anorexia, apatia, taquicardia, arritmia, pulso venoso jugular positivo e decúbito. Nas necropsias, os achados macroscópicos foram hidropericárdio, palidez dos rins e do miocárdio, atrofia gelatinosa da gordura cardíaca, evidenciação do padrão lobular hepático e edema pulmonar. Os principais achados microscópicos foram tumefação e vacuolização de cardiomiócitos, necrose de fibras cardíacas e infiltrado inflamatório mononuclear no miocárdio. Nos rins foi encontrada marcante degeneração hidrópico-vacuolar difusa. Os achados demonstraram nos caprinos cronicamente intoxicados, quadro clínico-patológico com características distintas do observado na forma aguda da intoxicação por P. marcgravii. Essas observações comprovam o risco para caprinos da ingestão da planta, mesmo que em pequenas doses, resultando no surgimento de quadro clínico e graves lesões ainda pouco conhecidas, e que poderiam ser confundidas com outras enfermidades.

    Staphylococcus caprae is an emerging microorganism in human bone and joint infections (BJI). The aim of this study is to describe the features of S. caprae isolates involved in BJI (H for human) compared with those of isolates recovered in goat mastitis (A for animal). Fourteen isolates of each origin were included. Identifications were performed using a Vitek 2 GP ID card, tuf gene sequencing, and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) Vitek MS. Molecular typing was carried out using pulsed-field gel electrophoresis (PFGE) and DiversiLab technology. The crystal violet method was used to determine biofilm-forming ability. Virulence factors were searched by PCR. Vitek MS technology provides an accurate identification for the two types of isolates compared to that of gold-standard sequencing (sensitivity, 96.4%), whereas the Vitek 2 GP ID card was more effective for H isolates. Molecular typing methods revealed two distinct lineages corresponding to the origin despite few overlaps: H and A. In our experimental conditions, no significant difference was observed in biofilm production ability between H and A isolates. Nine isolates (5 H isolates and 4 A isolates) behaved as weak producers while one A isolate was a strong producer. Concerning virulence factors, the autolysin atlC and the serine aspartate adhesin (sdrZ) genes were detected in 24 isolates (86%), whereas the lipase gene was always detected, except in one H isolate (96%). The ica operon was present in 23 isolates (82%). Fibrinogen-binding (fbe) or collagen-binding (cna) genes were not detected by using primers designed for Staphylococcus aureus or Staphylococcus epidermidis, even in low stringency conditions. Although S. caprae probably remains underestimated in human infections, further studies are needed to better understand the evolution and the adaptation of this species to its host. PMID:26511738

  11. Inert matrices, uranium-free plutonium fuels and americium targets. Synthesis of CAPRA, SPIN and EFTTRA studies

    International Nuclear Information System (INIS)

    A first selection of inert-matrix materials, actinide support alone (Pu and Am based), and compound materials, U free plutonium burning fuels and heterogeneous americium targets are discussed. Basic properties, fabrication, and reprocessing studies, European in-pile and out-of-pile tests, performed recently in the framework of CAPRA, SPIN and EFTTRA programs, are reviewed here. Taking into account these studies and on the bases of the different requirements to be met in each of the fuels and targets, a number of materials have been selected as 'promising candidates'. Trends for further research on these materials are established. (author)

    Full Text Available Este estudo estabelece a soroprevalência de Neospora caninum e Toxoplasma gondii em rebanhos caprinos no Sul de Minas Gerais e verifica a sua associação com o desempenho reprodutivo dos rebanhos analisados, uma vez que não há dados sobre neosporose em caprinos neste Estado. Amostras de soro de 401 caprinos provenientes de 11 propriedades foram submetidas à reação de imunofluorescência indireta anti-N. caninum e T. gondii. A prevalência média de animais positivos foi de 10,7% e 21,4%, respectivamente. Houve diferença significativa entre as faixas etárias. Neste quesito os maiores índices de positividade, para ambos os parasitas, foram observados nos caprinos acima de três anos de idade. Estes apresentaram uma probabilidade 2,6 e 4,8 maior, em relação aos animais de até um ano de idade, para N. caninum e T. gondii, respectivamente. No teste T não houve associação positiva entre as médias de prevalência de N. caninum (p=0,553 e T. gondii (p=0,098 com a ocorrência de problema reprodutivo nos rebanhos. Porém, propriedades com histórico de problemas reprodutivos apresentaram uma média de reagentes para N. caninum de 18,64%, se comparadas a 13,97% de criatórios que não relataram essas alterações. Quando os problemas reprodutivos foram separados em categorias a relação entre a ocorrência de aborto e a soroprevalência de N. caninum e de T. gondii foi significativa (p0,05 entre as médias de prevalência de T. gondii e o acesso de gatos ao rebanho no teste T. Entretanto, a média de prevalência nas propriedades em que os gatos tinham acesso foi de 31,01%, se comparada a 17,34% em criatórios onde não existiam gatos. Foi constatado o acesso de cães em 100% das propriedades. Os resultados obtidos neste estudo demonstram que N. caninum e T. gondii infectam caprinos no Sul de Minas Gerais e que estes parasitas podem estar associados à ocorrência de abortos nessa espécie animal.

    Full Text Available Wildlife monitoring and the identification of factors associated with disease outbreaks are major goals in wildlife conservation. We reviewed demographic and epidemiological data for the Alpine ibex Capra ibex from 1975–2013 to characterize the species’ abundance and distribution dynamics on a large scale. We also explored methodological bias in monitoring and analyzed the factors potentially associated with the risk of disease outbreaks. Our results revealed that the overall abundance and distribution of Alpine ibex appeared to be increasing at both national and international scales, in agreement with the IUCN’s ‘Least Concern’ conservation status on the international scale and on the national scale for Italy, Switzerland and France. Our comparative analysis of common monitoring methods highlights the fact that abundance values from counts are underestimated and suggests that the Alpine ibex is more abundant than is usually reported. The appearance and persistence of disease outbreaks (e.g. sarcoptic mange, keratoconjunctivitis or brucellosis are related to local ibex density and abundance. The observed correlation between the demographic growth of ibex populations and disease outbreaks suggests that the risk of epizooties may be increasing or might already be high in several populations of Capra ibex.

    Full Text Available O presente estudo descreve um surto de intoxicação por triclorfon em caprinos, que receberam pela via oral, a dosagem terapêutica do princípio ativo em questão (100mg/kg, provenientes da Universidade Estadual de Maringá, campus de Umuarama, PR. Cinquenta e três ovinos foram tratados com a mesma formulação/solução e não se observou nenhum efeito colateral nos animais referente ao tratamento com triclorfon. Das 20 cabras medicadas, cerca de 40 minutos após a administração do triclorfon, oito apresentaram os clássicos sinais clínicos de ataxia, decúbito externo-lateral, sialorreia, tremores, constrição das pupilas, dispneia com ruídos, micção e defecação involuntária, paresia espástica, timpanismo e lacrimejamento. Quase que imediatamente após a detecção destes sinais, as oito cabras foram medicadas com sulfato de atropina 1% 0,5mg/kg mais fluidoterapia. Cinco destes animais tiveram de receber nova dosagem de sulfato de atropina uma hora após a primeira aplicação, em função de alguns sinais clínicos, como tremores musculares, ainda estarem presentes. De 48 a 72 horas após a administração do triclorfon, três destes cinco animais vieram a óbito. Na necropsia, foi possível observar mucosas cianóticas, congestão de fígado, baço e rins, vasos mesentéricos congestos, vesícula biliar repleta, enfisema pulmonar, parênquima pulmonar avermelhado. Os resultados encontrados neste trabalho chamam atenção que o surto aconteceu em cabras adultas, que apresentavam boas condições clínicas e acima de tudo, receberam a dosagem terapêutica recomendada em bula pelo fabricante. Talvez isso possa indicar alguma sensibilidade mais elevada desta espécie animal à dosagem recomendada em bula do triclorfon (100mg/kg para caprinos.

    Full Text Available Resumo: A intoxicação por plantas é sabidamente uma das principais causas de morte de bovinos adultos no Brasil. Uma vez que pouco pode ser feito no que diz respeito ao tratamento destas intoxicações, os esforços devem se concentrar na adoção de medidas profiláticas alternativas, como a utilização de uma espécie menos sensível no local de ocorrência de determinadas plantas. Objetivou-se com esse trabalho verificar a sensibilidade de caprinos às crotalárias (Crotalaria spectabilis e Crotalaria juncea para que estes possam ser utilizados na profilaxia da intoxicação por essas plantas em bovinos. Sementes de C. spectabilis e C. juncea foram fornecidas em doses únicas ou diárias a oito caprinos adultos jovens, de ambos os sexos, divididos aleatoriamente em dois grupos de quatro animais (um grupo para cada planta. Dos quatro caprinos que receberam as sementes de C. juncea, nenhum desenvolveu sinais clínicos de intoxicação ou apresentou alterações significativas no exame bioquímico. Entre os quatro caprinos que receberam sementes de C. spectabilis três morreram. Um animal recebeu uma dose única de 20g/kg de sementes da planta e desenvolveu sinais de intoxicação aguda, caracterizadas macro e microscopicamente por necrose hemorrágica centrolobular. Os outros dois caprinos desenvolveram um quadro de intoxicação crônica pela administração de doses diárias de 2g/kg de sementes da planta por 35 e 150 dias respectivamente. Um animal apresentou uma marcada pneumonia intersticial e lesões hepáticas leves, enquanto no outro caprino observaram-se apenas lesões hepáticas crônicas. Ambos os animais apresentaram alterações transitórias ao exame bioquímico. O quarto caprino recebeu a dose única de 10g/kg, sobreviveu e não apresentou alterações clínicas ou da bioquímica sanguínea significativas. Os resultados do trabalho mostraram que não se deve usar caprinos como medida profilática na intoxicação por C

Este trabalho relata a intoxicação experimental em caprinos por I. sericophylla e I. riedelii contendo 0,05% e 0,01% de swainsonina, respectivamente. Foram utilizados três grupos de quatro animais. O Grupo 1 recebeu doses diárias de 2g/kg peso vivo (pv de I. sericophylla dessecada (150mg de swainsonina/kg. Os caprinos deste grupo apresentaram sinais clínicos 36-38 dias após o início da ingestão. O Grupo 2 ingeriu diariamente 2g/kg de I. riedelii dessecada (30mg de swainsonina/kg por 70 dias. Como não foram observados sinais clínicos a dose de suainsonina foi aumentada para 60mg/kg por outros 70 dias. Os caprinos do Grupo 2 apresentaram sinais clínicos 26-65 dias após o aumento da dose de swainsonina para 60mg/kg. O Grupo 3 foi utilizado como controle. Neste experimento, a menor dose tóxica de swainsonina foi de 60mg/kg, que representa 0,0004% da matéria seca, em caprinos ingerindo 1,5% pv de matéria seca. Para caprinos ingerindo 2%-2,5% pv de matéria seca essa dose corresponderia a 0,00024%-0,0003 % da matéria seca.

    Host acquired immunity is a critical factor that conditions the survival of parasites. Nevertheless, there is a shortage of data concerning inter-individual immunological inequalities in wild mammals. Sarcoptic mange is a widespread parasitosis that severely affects mammals such as the Iberian ibex (Capra pyrenaica). Despite some work on the subject, the immune response to sarcoptic mange infestation is still a complex and poorly understood phenomenon. To improve knowledge of the host-Sarcoptes immunological interaction, 18 Iberian ibexes were experimentally infested. IgG levels were assessed using ELISA to test for potential factors determining the specific immune response to infestation. Previous exposure and sex appeared to affect the IgG response to infestation and our results suggest a sex-biased immunomodulation. We discuss the immunological pattern of host-Sarcoptes interactions and also suggest further lines of work that may improve the understanding of immunological interactions of host-Sarcoptes systems.

    Full Text Available No Brasil, estima-se que as intoxicações por plantas tóxicas que contém monofluoroacetato de sódio (MFA causam a morte de aproximadamente 500.000 bovinosao ano. A inoculação ruminal de bactérias que degradam MFA tem sido proposta como uma forma de prevenir a intoxicação. O presente trabalho teve como objetivo avaliar, em caprinos, a resistência ao MFA presente em Amorimia septentrionalis, induzida por inoculação ruminal das bactérias Pigmentiphaga kullae e Ancylobacter dichloromethanicus. Doze caprinos, que nunca tiveram contato prévio com plantas que contêm MFA, foram divididos em dois grupos, com seis animais cada. No grupo 1, 60 mL de uma mistura das duas bactérias foi inoculada, diariamente, durante 10 dias em cada caprino. No grupo 2, os caprinos não receberam as bactérias. A partir do 10º dia de inoculação, A. septentrionalis foi administrada, diariamente, na dose de 5g/kg de peso vivo, sendo interrompida em cada animal após a observação dos primeiros sinais clínicos da intoxicação. Os caprinos do grupo 1 apresentaram sinais clínicos 5,83±2,56 dias após a administração da planta o que diferiu significativamente (p=0,037 dos caprinos do grupo 2, que apresentaram sinais clínicos aos 2,67±0,52 dias.

Após ajuste dos modelos procedeu-se estudo dos efeitos ambientais sobre a curva decrescimento, sendo considerados os efeitos de ano, estação, tipo de nascimento, sexo e rebanho. As médias dos pesos foram baixas, indicando reflexo do sistema de criação extensivo adotado. O modelo de Gompertz apresentou melhor ajuste, de acordo com os critérios QMR, R², percentual de convergência, comportamento gráfico e DMA. Constatou-se influência significativa (p<0,05 dos efeitos de ano e estação de nascimento, tipo de nascimento, sexo e rebanho sobre os parâmetros A, B e k da curva de crescimento ajustada e sobre os pesos estimados a partir da curva ajustada. A Taxa de Crescimento Absoluta máxima foi observada precocemente aos 35 dias de idade, indicando que os animais sofreram déficit nutricional que refletem no crescimento, principalmente na fase pós desmama. As herdabilidades estimadas para os parâmetros da curva foram de baixa magnitude, resultando em pequena alteração do padrão de crescimento dos animais estudadospor meio de seleção individual. A baixa variância genética para os parâmetros da curva ajustada é conseqüência das limitações amostrais do banco de dados.

    Full Text Available Aim of study: To manage and conserve wild populations effectively, a good understating of population density is critical. During 2010, the density of Iberian wild goat Capra pyrenaica and mouflon Ovis aries were estimated.Area of study: The area is situated in Muela de Cortes Game Reservation (Spain, a Mediterranean forest plateau, after a mange Sarcoptes scabiei outbreak that affected both species. Material and methods: To measure the abundance, sex ratio and productivity of the Iberian wild goat and mouflon. Field work was conducted during spring (after parturition and autumn (during rut by walking along itineraries, using a Distance Sampling approach. Main results: Based on DS, the best relative fit of model and adjustment term for Iberian wild goat was hazard-rate cosine, based on the lowest AIC score. The average density for Iberian wild goat was 4 km-2 (95% CI: 2,3 – 6,9 (after parturition and 3,6 km-2 (95% CI: 2 – 6.6 (during rut. Average estimation was 1,422 goats (95% CI: 813 – 2,487 after parturition and 1,308 during rut (95% CI: 725 – 2,362. Mouflon best relative fit of model and adjustment term was uniform cosine after parturition, based on the lowest AIC score. The best relative fit of model and adjustment term for mouflon was hazard-rate cosine, based on the lowest AIC score. The average density was 6.8 mouflon km-2 (95% CI: 4.7 – 9,9 after parturition and 7,4 mouflon km-2 (95% CI: 4,4 – 12,5 during rut. Average estimation was 2,440 mouflon after parturition (95% CI: 1,673 – 3,558 and 2,678 during rut (95% CI: 1,589 – 4,515. Research highlights: The area represents one of the largest continental free-living populations of mouflon in Europe and a relevant area for Iberian wild goat, where it has survived for centuries and spread into the East Iberia. This study suggests that the survey methods used are suitable and sustainable with available field personnel for quantifying changes in wild goat and mouflon populations

Según esta base de datos, la misma tendencia se observa en el consumo per cápita de carne ovino-caprina que partiendo de 270 g/persona/año para el 2000 llega a 370 g/persona/año para el 2008. Este crecimiento en el inventario y el consumo per cápita del ovino-caprino impulsa la necesidad de aprovechar no solo las ventajas comparativas, sino también la generación de ventajas competitivas que lleven a la ovino-cultura y la caprino-cultura colombiana por el camino de la competitividad y la globalización, aprovechando las oportunidades en el mercado nacional y de exportación. El eficaz aprovechamiento de dichas ventajas implica la incorporación de los datos, la información y el conocimiento como factores de producción dentro de un proceso ordenado, bajo el marco de un sistema de “gestión de conocimiento”. El presente documento trata los fundamentos teóricos sobre los cuales se discute la manera como los datos, la información y el conocimiento se transforman en productividad y competitividad; se tratan los temas del “Big-Bang”, la entropía y neguentropía, la complejidad, la teoría de sistemas, la teoría del conocimiento, la epistemología, el management, la economía del conocimiento, la planeación estratégica, la espiral del conocimiento en las organizaciones, y la gestión del conocimiento, procurando algunas aproximaciones al sector agropecuario y la contextualización de la gestión del conocimiento en la ovino-cultura y caprino-cultura colombiana.

    Full Text Available Ipomoea pes-caprae (L. R. Br., Convolvulaceae, is a medicinal plant that grows abundantly as a pan-tropical stand plant. The 3² (two factors and three levels factorial design, was applied to determine the best time and drug/solvent proportion to maximize the flavonoid content in the hydroethanolic extract by maceration process. The antinociceptive and anti-inflammatory effects were studied at 5-20 mg/kg, i.p., using the writhing test and carrageenan-induced pleurisy models in mice. The optimized extract was able to inhibit more than 50% of abdominal writhing at 20 mg/kg, with 55.88%±2.4 of maximum inhibition. Indomethacin, used as positive control, inhibited 64.86% at 10 mg/kg. In the pleurisy model, the extract produced dose-dependent inhibition of the first phase of inflammation (4 h in the pleural cavity induced by injection of carrageenan (1% in mice. It inhibited 50%±0.82 (p<0.01 of exudation induced by carrageenan, and 60.88%±0.14 (p<0.01 of leukocyte migration to the pleural cavity. In conclusion, the results validate the technological conditions of the maceration process to produce an optimized bioactive herb extract for the development of analgesic and anti-inflammatory phytopharmaceuticals using 70 ºGL ethanol, a plant to solvent ratio of 12.5% (w/v, and ten days of maceration.

    Peste des petits ruminants virus (PPRV) is the causative agent of peste des petits ruminants (PPR). The spread of PPR often causes severe economic losses. Therefore, special attention should be paid to the surveillance of PPR emergence, spread, and geographic distribution. Here we describe a novel mutant of PPRV China/XJBZ/2015 that was isolated from Capra ibex in Xinjiang province in China 2015. The sequence analysis and phylogenetic assessment indicate that China/XJBZ/2015 belongs to lineage IV, being closely related to China/XJYL/2013 strain. Interestingly, the V protein sequence of China/XJBZ/2015 showed lower homology with other Chinese PPRVs isolated during 2013 to 2014 (94%~95%), whereas it shared 100% identity with three Tibet strains isolated in China 2007. The 3' UTR, V gene, and C gene were determined to be highly variable. Besides, 29 PPR genomic sequences available in GenBank were analyzed in this study. It is the first time to use PPRV genomic sequences to classify the different lineages which confirmed the lineage clustering of PPRVs using N gene 255 bp fragments and F gene 322 bp fragments. In conclusion, our findings indicate that the PPRVs continue to evolve in China, and some new mutations have emerged. PMID:26998489

    In the early 2000s, several colonies of Alpine ibex (Capra ibex ibex) in Switzerland ceased growing or began to decrease. Reproductive problems due to infections with abortive agents might have negatively affected recruitment. We assessed the presence of selected agents of abortion in Alpine ibex by serologic, molecular, and culture techniques and evaluated whether infection with these agents might have affected population densities. Blood and fecal samples were collected from 651 ibex in 14 colonies throughout the Swiss Alps between 2006 and 2008. All samples were negative for Salmonella spp., Neospora caninum, and Bovine Herpesvirus-1. Antibodies to Coxiella burnetii, Leptospira spp., Chlamydophila abortus, Toxoplasma gondii, and Bovine Viral Diarrhea virus were detected in at least one ibex. Positive serologic results for Brucella spp. likely were false. Overall, 73 samples (11.2%) were antibody-positive for at least one abortive agent. Prevalence was highest for Leptospira spp. (7.9%, 95% CI=5.0-11.7). The low prevalences and the absence of significant differences between colonies with opposite population trends suggest these pathogens do not play a significant role in the population dynamics of Swiss ibex. Alpine ibex do not seem to be a reservoir for these abortive agents or an important source of infection for domestic livestock in Switzerland. Finally, although interactions on summer pastures occur frequently, spillover from infected livestock to free-ranging ibex apparently is uncommon. PMID:21719818

    Sarcoptic mange is a contagious skin disease caused by Sarcoptes scabiei, affecting both domestic and wild mammals, including the Iberian ibex (Capra pyrenaica), a medium-sized mountain ungulate almost endemic to the Iberian Peninsula. Acute phase proteins (APPs) could be an indicator of sarcoptic mange disease and severity in Iberian ibex. Serum samples from 131 healthy and sarcoptic mange-affected Iberian ibexes were collected from 2005 to 2012 in Sierra Nevada Natural Space in southern Spain. Serum alpha-1-acid glycoprotein (AGP), serum amyloid A (SAA) and haptoglobin (Hp) concentrations were quantified, and statistically significant differences according to sarcoptic mange disease and severity were assessed. Both AGP and SAA were significantly higher in the sarcoptic mange-affected ibexes than in the healthy ones as well as in the severely affected ibexes as compared to those with less than 50 % of the body surface affected. For the first time, changes in APP are reported in relation to sarcoptic mange in Iberian ibex. It is also reported for the first time that the intensity of APP increase depends on the severity of sarcoptic mange, which could be related with the pathological secondary amyloidosis, leading to organ dysfunction in severely mange-affected animals. Species and population differences in the increase of APP in response to sarcoptic mange could indicate individual and population differences in the immune capability of each population to deal with mange, population prevalence and mortality being the last indicators of such sensitivity.

    The aims of this study were to determine the reproductive seasonality of four captive markhor goats (Capra falconeri heptneri), to characterize semen collected by electroejaculation, and to compare extenders and processing techniques for semen cryopreservation. Over the course of 1 yr, mean monthly scrotal circumference, serum testosterone, and fecal testosterone were measured and found to be inversely associated with day length. Maximum scrotal circumference (25.2 +/- 0.9 cm), serum testosterone (521.0 +/- 103.4 ng/dl), and fecal testosterone (382.5 +/- 90.3 ng/g) occurred in November, when day length was short (9.7 +/- 0.1 hr). Once a month for 3 mo (December, January, and February), bucks were anesthetized for electroejaculation and semen evaluation. Semen samples were divided into six aliquots for extension and cryopreservation in soy-based Bioxcell or Tris-based extender with 5 or 15% egg yolk, with and without centrifugation. Samples were then thawed for repeat evaluation 1-3 mo later. Postthaw evaluation revealed no significant differences between centrifuged and noncentrifuged samples. Sperm in Tris 5% and 15% egg yolk displayed higher total motility at 0, 3, and 6 hr postthaw and higher progressive motility postthaw compared with sperm in Bioxcell (P < 0.05). Sperm in Bioxcell displayed higher viability than sperm in both Tris-egg yolk extenders (P < 0.01), more intact acrosomes than sperm in Tris-15% egg yolk (P < 0.05), and a tendency for more intact acrosomes than sperm in Tris-5% egg yolk (P < 0.10). Sperm in Tris-5% egg yolk tended to have a higher percentage of morphologically normal sperm compared with Bioxcell (P < 0.10). This study provides evidence that markhor goats exhibit seasonality in scrotal circumference and testosterone levels and that centrifugation may be eliminated from the processing of markhor semen.

    Full Text Available Ipomoea pes-caprae is a sand dune plant commonly used as folklore medicine for fisherman communities based on the traditional knowledge. Little information is available on the feasibility of applying micropropagation techniques for production of dune and marsh species. The main aim of this study is to increase the callus induction and shoot generation of sand dune plant Ipomoea pes-caprae with easily available low cost natural materials. Coconut water is the rich source of carbohydrate and other nutrients which enhance callus and plant regeneration. In our present study, we tried different type of MS medium (Full and half strength with coconut water at three different percentage (10, 15, 20% and different concentration of plant growth regulators for callus induction and shoot regeneration. Well-developed callus inoculated in full and half strength MS medium with different concentration of CW and plant growth regulators. The best results were accomplished with half strength MS medium with 15% coconut water and with 2, 4-D and IAA 0.7 mg L-1 concentration which shows better callus induction and shoot regeneration. Young shoot and root developed plants transferred to green house and then followed to soil.

    Full Text Available Mascagnia rigida é a planta tóxica mais importante para bovinos na região Nordeste, causando morte súbita associada ao exercício. O presente trabalho teve como objetivos descrever três surtos de intoxicação por M. rigida em ovinos e um surto em caprinos no semi-árido da Paraíba, reproduzir experimentalmente a intoxicação em ovinos e caprinos, e comprovar a passagem do princípio ativo de M. rigida pelo colostro destes pequenos ruminantes. Os surtos ocorreram no início do período chuvoso, quando a planta brota antes do que outras forrageiras ou após o final desse período, quando após secarem algumas forrageiras, M. rigida permanece verde. Na reprodução experimental da intoxicação por M. rigida, doses de 10 e 20g/kg de peso animal, com as planta proveniente de duas regiões diferentes, foram letais para três caprinos e três ovinos. Um caprino que ingeriu 20g/kg da planta um ovino que ingeriu 10g/kg, se recuperaram. Dois ovinos e dois caprinos que ingeriram 5g/kg tiveram sinais discretos e se recuperaram. Tanto os casos experimentais quanto os espontâneos apresentaram ingurgitamento das veias jugulares, relutância em caminhar, decúbito externo abdominal, incoordenação, respiração ofegante, depressão, instabilidade e tremores musculares. A morte ocorreu após um curso clínico de alguns minutos a 27h40 min. As principais lesões foram edema pulmonar e vacuolização e necrose de células epiteliais dos túbulos renais. Para testar se o princípio ativo de M. rigida é eliminado pelo leite causando morte súbita nas crias foi realizado um experimento com duas cabras e cinco ovelhas que ingeriram, diariamente, 2g/kg de M. rigida, nos 15 dias anteriores ao parto. Uma ovelha que tinha gestação gemelar abortou depois de ter ingerido a planta por 10 dias. Os cordeiros das demais ovelhas mamaram normalmente o colostro sem aprestar sinais clínicos. O cabrito de uma cabra mamou o colostro e 5 minutos após morreu subitamente

    2002-01-01

    Full Text Available Este trabalho inclui os estudos clínicos e patológicos da doença de armazenamento lisossomal induzida pelo consumo espontâneo de Sida carpinifolia. A enfermidade foi observada em três rebanhos, que juntos eram compostos por 51 caprinos, dos quais, 25 foram afetados e 11 necropsiados. Nos três surtos, S. carpinifolia era a vegetação predominante nos piquetes ocupados pelos animais. Clinicamente, a doença caracterizou-se por distúrbios neurológicos que consistiam de ataxia, hipermetria, posturas anormais, tremores musculares afetando principalmente as regiões da cabeça e pescoço, dificuldade para ingestão de alimentos e quedas freqüentes. Estes sinais clínicos eram exacerbados pela movimentação. Em alguns animais, embora com um quadro clínico estabilizado, as alterações neurológicas persistiram durante 24 meses após sua retirada dos piquetes infestados por S. carpinifolia. A doença foi reproduzida administrando-se S. carpinifolia, in natura ou seca à sombra, para 3 caprinos. Um caprino recebeu Sida rhombifolia, ad libidum, por 40 dias e não desenvolveu alterações clínicas ou patológicas. Na necropsia não havia alterações. Microscopicamente, as principais alterações foram distensão e vacuolização citoplasmáticas em neurônios e, em menor intensidade, em células da glia do sistema nervoso central. Alterações similares foram observadas em células acinares pancreáticas, hepatócitos, células tubulares renais, células foliculares epiteliais da tireóide e macrófagos de órgãos linfóides. Nos animais que não mais ingeriam S. carpinifolia por períodos de um mês ou mais, observou-se uma diminuição da vacuolização citoplasmática de neurônios, que apresentavam citoplasma eosinofílico e aspecto enrugado. Nestes casos, notou-se também desaparecimento neuronal especialmente em células de Purkinje e gliose local. Em cortes cerebelares, esta doença de armazenamento foi caracterizada como ?-manosidose

Entre as doenças infecciosas foram observados cinco casos de ectima contagioso, dois casos de paratuberculose e dois casos de pitiose gastrointestinal. Em sete animais suspeitou-se de enterotoxemia e 31 casos foram diagnosticados como enterite inespecífica. A não utilização de práticas de controle integrado de parasitas e a utilização de alimentos inadequados durante o período de escassez de forragem contribuiu para a ocorrência de um grande número de doenças. A prática de conservação de forragens poderia reduzir substancialmente a ocorrência de distúrbios digestivos na região semiárida.

    2003-01-01

    Full Text Available En los caprinos locales del norte de México, en particular los de la Comarca Lagunera (26°N, existe una estacionalidad reproductiva. En los machos el periodo de reposo sexual ocurre de enero a abril, mientras que en las hembras, el periodo de anestro sucede de marzo a agosto. En ambos sexos, esta estacionalidad es provocada por las variaciones de la duración del día. Los días cortos estimulan la actividad sexual y los días largos la inhiben. Asimismo, la exposición a 2.5 meses de días largos por sí sola o seguida por la aplicación de dos implantes subcutáneos de melatonina, estimulan la actividad sexual de los machos de febrero a abril. En las hembras, el efecto macho es capaz de inducir el estro y la ovulación durante el anestro estacional, solamente si se utilizan machos inducidos a una intensa actividad sexual mediante un tratamiento fotoperiódico. Los machos tratados con días largos, seguidos o no de la aplicación de melatonina, inducen la actividad sexual de 100% de las hembras en anestro, mientras que los machos testigos, en reposo sexual, inducen solamente alrededor de 10% de éstas. Estos resultados indican que la respuesta de las cabras al efecto macho depende de la intensidad de la actividad sexual de los machos.

    Our study focuses on the Iberian ibex (Capra pyrenaica) from the Sierra Nevada Natural Space (southern Spain), where sarcoptic mange is an endemic disease and animals are affected by a highly seasonal environment. Our aim was to distinguish between disease and environmental influences on seasonal variation in body weight, hematology, and serum biochemistry in Iberian ibex. We sampled 136 chemically immobilized male ibexes. The single effect of mange influenced hemoglobin, hematocrit, mean corpuscular volume, leukocytes, band neutrophils, monocytes, cholesterol, urea, creatine, and aspartate aminotransferase. Both mange and the period of the year also affected values of mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, neutrophils, glucose, and serum proteins. Scabietic animals showed a marked reduction in body weight (21.4 kg on average), which was more pronounced in winter. These results reveal that 1) infested animals are anemic, 2) secondary infections likely occur, and 3) sarcoptic mange is catabolic. PMID:25380360

No primeiro experimento a planta fresca colhida na época de estiagem e na época de chuvas foi administrada a 16 caprinos. A planta colhida na estiagem foi tóxica na dose diária de 5 e 10g por kg de peso animal (g/kg. A planta colhida na época de chuva foi tóxica na dose diária de 20 e 30g/kg, demonstrando que a planta é mais tóxica durante o período seco. A planta seca, colhida na época de estiagem foi administrada a 9 caprinos em doses diárias de 1.7, 2, 3.4 e 5.1g/kg. Doses de 3, 4 e 5.1g/kg causaram sinais clínicos, demonstrando que a planta mantém a toxicidade após a secagem. A planta fresca colhida na época de estiagem e na época de chuvas foi administrada a 10 ovinos. A planta colhida na estiagem foi tóxica na dose diária de 5g/kg e na época de chuva foi tóxica nas doses de 10 e 20g/kg. Estes resultados sugerem a maior susceptibilidade dos ovinos à intoxicação do que os caprinos. Como alguns produtores mencionam que cordeiros lactentes que não estão pastando se intoxicam através do leite, I. asarifolia foi administrada diariamente nas doses de 2.5, 5 e 10g/kg a 5 ovelhas, a partir do dia do parto (2 ovelhas, do último dia de prenhez (1 ovelha e 60 dias antes da parição (2 ovelhas.

    Genetic diversity in populations of invasive species is influenced by a variety of factors including reproductive systems, ploidy level, stochastic forces associated with colonization and multiple introductions followed by admixture. Here, we compare genetic variation in native and introduced populations of the clonal plant Oxalis pes-caprae to investigate the influence of reproductive mode and ploidy on levels of diversity. This species is a tristylous geophyte native to South Africa. Invasive populations throughout much of the introduced range are composed of a sterile clonal pentaploid short-styled form. We examined morph ratios, ploidy level, reproductive mode and genetic diversity at nuclear microsatellite loci in 10 and 12 populations from South Africa and the Western Mediterranean region, respectively. Flow cytometry confirmed earlier reports of diploids and tetraploids in the native range, with a single population containing pentaploid individuals. Introduced populations were composed mainly of pentaploids, but sexual tetraploids were also found. There was clear genetic differentiation between ploidy levels, but sexual populations from both regions were not significantly different in levels of diversity. Invasive populations of the pentaploid exhibited dramatically reduced levels of diversity but were not genetically uniform. The occurrence of mixed ploidy levels and stylar polymorphism in the introduced range is consistent with multiple introductions to the Western Mediterranean. This inference was supported by variation patterns at microsatellite loci. Our study indicates that some invasive populations of Oxalis pes-caprae are not entirely clonal, as often assumed, and multiple introductions and recombination have the potential to increase genetic variation in the introduced range.

Foram realizadas oito coletas de sêmen de sete reprodutores soropositivos para o LVC: quatro antes dos animais sofrerem dano testicular e quatro depois. Entre as coletas realizadas na mesma semana, em uma, o ejaculado era lavado, para retirada do plasma seminal, e na outra, não. O DNA pró-viral do LVC foi identificado pela reação em cadeia da polimerase Nested (PCR Nested, e pelo isolamento viral. O vírus foi isolado em 7,1% das amostras. A PCR identificou o DNA pró-viral em 35,7% do total das amostras: 17,9% nas amostras lavadas e 53,6% das amostras de sêmen integrais. O dano ao testículo permite maior fluxo do vírus para o sêmen, pois antes do dano, 21,4% das amostras foram positivas e pós-dano, 50%. A transmissão do LVC pelo sêmen de reprodutores caprinos é potencializada pela presença de inflamações testiculares e pelo fato de o sêmen criopreservado conter o LVC na forma infectante.The objective of this work was to evaluate the presence of the DNA provirus of the caprine lentivirus (LVC in ejaculates of naturally infected males, and to verify the influence of the wash of the semen as well as the presence of testicle inflammation on the viral load.

    Full Text Available RESUMODiversos fatores predisponentes são descritos para as afecções mamárias ou distúrbios secundários que comprometem a qualidade e produtividade de leite de fêmeas nas diferentes espécies. As características fenotípicas do úbere são consideradas na avaliação econômica de uma fêmea caprina, tanto pelo potencial de produção como pelo registro genealógico dessa fêmea. A limitação de estudos correlacionando essas características com a saúde do úbere gera a dúvida a respeito do significado da conformação do mesmo à saúde e produtividade da glândula mamária. Sendo assim, este estudo teve como objetivo relacionar os parâmetros da conformação do úbere com a celularidade da glândula mamária aferida pelo teste California Mastitis Test (CMT e contagem de células somáticas (CCS em 80 cabras da raça Saanen sem alterações no exame clínico da glândula mamária nem no teste de Tamis. Observou-se que a maioria dos parâmetros fenotípicos de úbere não influenciou a CCS, sendo considerados puramente estéticos. A circunferência e profundidade de úbere demonstraram correlação negativa com a celularidade e, por serem características de herdabilidade moderada a alta, podem ser parâmetros considerados para seleção genética de caprinos.

O objetivo deste trabalho foi desenvolver um teste de imunofluorescência indireta (IFA, utilizando isolados brasileiros de SRLV, para o diagnóstico sorológico de infecção por estes agentes em caprinos. A técnica de IFA foi comparada, quanto à sensibilidade e à especificidade, ao teste de AGID com antígeno do vírus Maedi-Visna WLC-1. Cultivos celulares secundários de membrana sinovial ovina infectadas com dois isolados de SRLV de origem caprina (CAEV Br/UFRGS-2 e CAEV Br/UFRGS-5 foram utilizados para o teste de IFA. Duzentas e trinta e nove amostras de soro caprino foram submetidas aos dois testes. O teste de AGID detectou 129 (53.9% amostras de soro caprino com anticorpos para SRLV. O teste de IFA detectou mais amostras reagentes, sendo que resultados diferentes foram observados de acordo com o isolado de SRLV empregado.

    Full Text Available ResumenLa hidatidosis es una enfermedad parasitaria de distribución mundial que es causada por el cestodo Echinococcus granulosus, en Chile es considerada una enfermedad endémica, importante en problema de Salud Pública. En los últimos años se ha observado una baja en la hidatidosis animal a nivel de mataderos, a excepción de los caprinos que han aumentado su porcentaje de infección. Esta especie es una importante fuente de recursos económicos para la población ruralen muchas regiones del país, entre ellas los municipio de Til Til y Colina, , donde se encuentra la mayor cantidad de ejemplares caprinos dentro de la de la Región Metropolitana En la actualidad existe poca información de estudios para hidatidosis en animales vivos, por esta razón se decidió determinar la prevalencia serológica en caprinos de la Región Metropolitana. Se estudiaron 524 animales, 262 correspondientes a Colina y 262 de Til Til, los animales fueron escogidos completamente al azar y el total de ejemplares fué estimado estadísticamente. Las muestras de sangre fueron recolectadas en papel filtro, siendo analizadas mediante la técnica de ELISA IgG caprina y bajo los estándares establecidos. La prevalencia para hidatidosis caprina en los sectores estudiados fue de un 4,38 % en total en elsector. Las diferencias en la seropositividad entre los predios estudiados se deberían, probablemente, a las diferencias en losmanejos sanitarios respectivos. Estos resultados son ignificativamente menores con respecto a los observados en otras regiones ( Ej.Coquimbo, 40,9%, a pesar de ello, es una significativacontribución al conocimiento de la hidatidosis en una importante especie animal de la Región Metropolitana, los que viven en estrecho contacto con perros y el hombre aumentando así las posibilidadesde transmisión de la enfemedad.

Quatro caprinos foram necropsiados e amostras de vísceras foram coletadas para exame histológico. As principais alterações clínicas foram: apatia, anorexia, cabeça apoiada contra obstáculos, decúbito e morte. Achados macroscópicos incluíram sufusões no epicárdio e endocárdio; fígado levemente amarelado e com padrão lobular evidente e, em um caso, acompanhado de hemorragias multifocais. Na histologia observou-se necrose hepática, que variava de centrolobular a massiva, compatível com hepatopatia tóxica. No SNC havia satelitose, tumefação neuronal, edema periaxonal, perivascular. O diagnóstico de intoxicação por Trema micrantha foi baseado no quadro clínico e lesional de hepatite tóxica associado ao uso da planta para alimentação de caprinos.Twenty five goats, maintained in paddocks, had died in five subsequent days after have been offered leaves, mixed in the ration, of Trema micrantha, a tree commonly called grandiúva. Four animals were necropsied and samples were collected for histopathology. Clinical signs included apathy, anorexia, head pressing against obstacles, decubitus and death. Macroscopic findings included suffusions in the epi- and endocardium, a yellowish liver with pronounced lobular pattern, in one goat, the liver presented additionally multiple visible hemorrhages. Histological examination revealed centrilobular to massive hepatic necrosis consistent with acute liver toxicosis. In the brain, satelitosis, neuronal swelling, and perineuronal and perivascular edema was found. The diagnosis of poisoning by Trema micrantha was based in the clinical picture characteristic of toxic hepatitis associated in the feeding of the plant to the goats.

Em todas as propriedades visitadas as pastagens eram constituídas de campo nativo, tinham pouca disponibilidade de forragem e I. carnea subsp. fistulosa encontrava-se em grande quantidade. Nas três propriedades onde eram criados caprinos foram observados animais com sinais nervosos, incluindo tremores de intenção, aumento da base de sustentação quando em estação, ataxia, hipermetria, nistagmo, paresia espástica ou debilidade, alterações posturais, perda de equilíbrio e quedas. Em duas fazendas a prevalência foi de 32% (23/71 e 100% (32/32 e em outra havia um animal com sinais acentuados e o resto do rebanho, de 19 caprinos, não foi examinado clinicamente. Bovinos, ovinos e bubalinos não foram afetados. Foram eutanasiados e necropsiados seis caprinos que apresentavam sinais clínicos acentuados. Macroscopicamente não foram observadas alterações. Na histologia observou-se vacuolização do pericário de neurônios e do citoplasma de células epiteliais da tireóide, rim, fígado, pâncreas e macrófagos de diversos órgãos. No sistema nervoso central a vacuolização era mais grave nos neurônios de Purkinje do cerebelo e nos neurônios dos núcleos cerebelares e do tronco encefálico. Observaram-se também degeneração walleriana dos axônios e gliose. A alta freqüência da intoxicação nas três fazendas que criavam caprinos sugere que a intoxicação por I. carnea subsp. fistulosa é muito importante para caprinos na Ilha de Marajó, onde há abundante quantidade da planta, que permanece verde durante todo o período seco.Ipomoea carnea subsp

    Sperm morphology has been identified as one characteristic which can be useful in prediction of fertility in a species. The development of computer automated sperm morphometry analysis allows for objective analysis of sperm head dimensions. The aim of the current study was to develop an optimum sampling procedure to characterize the Iberian ibex (Capra pyrenaica) sperm head morphometrically. Fresh semen from 11 males was collected using transrectal ultrasonic-guided massage of accessory sex glands and electroejaculation and prepared on slides for morphometric analysis to evaluate technical variation and standardize automated sperm morphometry analysis procedures by Sperm-Class Analyzer(®). Three staining methods (Diff-Quik(®), Hemacolor(®), Spermblue(®)), number of sperm cells necessary to sample and repeatability of the staining technique were assessed. There were significant differences in size of sperm head depending on stain used. Hemacolor(®) was stain most suitable for sperm head morphometry evaluation (length=8.42 μm; width=4.21 μm; area=29.37 μm(2); perimeter=21.93 μm; elongation=0.33; elipticity=2.01; regularity=0.95; rugosity=0.77). Morphometric values obtained from samples of 50, 100, 150, 175 and 200 sperm heads were compared. The most efficient method of analyzing sperm morphometry was to evaluate 100 sperm cells at 60× objective magnification. Thus, this study has allowed for description of optimal sample processing to determine morphometric parameters of sperm heads (size and shape) in Iberian ibex by Sperm-Class Analyzer(®) and provides a basis for future studies on the relationship with freezability and fertility in this species.

    The present study reports the effect of shortening the prefreezing equilibration time with glycerol on the quality of frozen-thawed ejaculated sperm from four Mediterranean mountain ungulates: Cantabrian chamois (Rupicapra pyrenaica), Iberian ibex (Capra pyrenaica), mouflon (Ovis musimon) and aoudad (Ammotragus lervia). Ejaculated sperm from these species were divided into two aliquots. One was diluted with either a Tris-citric acid-glucose based medium (TCG-glycerol; for chamois and ibex sperm) or a Tris-TES-glucose-based medium (TTG-glycerol; for mouflon and aoudad sperm), and maintained at 5°C for 3h prior to freezing. The other aliquot was diluted with either TCG (chamois and ibex sperm) or TTG (mouflon and aoudad sperm) and maintained at 5°C for 1h before adding glycerol (final concentration 5%). After a 15min equilibration period in the presence of glycerol, the samples were frozen. For the ibex, there was enhanced (P<0.05) sperm viability and acrosome integrity after the 3h as compared with the 15min equilibration time. For the chamois, subjective sperm motility and cell membrane functional integrity were less (P<0.05) following 15min of equilibration. In the mouflon, progressive sperm motility and acrosome integrity was less (P<0.05) when the equilibration time was reduced to 15min. For the aoudad, the majority of sperm variables measured were more desirable after the 3h equilibration time. The freezing-thawing processes reduced the sperm head size in all the species studied; however, the equilibration time further affected the frozen-thawed sperm head variables in a species-dependent fashion. While the equilibration time for chamois sperm might be shortened, this appears not to be the case for all ungulates. PMID:27346588

    Domestic goat (Capra hircus) is a very adaptable and geographically spread livestock species. Recent studies on mitochondrial DNA diversity suggest that goats have been the most widely transported and traded livestock species. For this reason it is thought to have played a central role in the demic spread of agriculture during the Neolithic agricultural revolution (Luikart et al. 2001).

    Full Text Available Utilizaram-se 526 registros de parições de cabras mestiças com o objetivo de avaliar a influência de alguns efeitos de ambiente sobre a prolificidade. As análises estatísticas foram realizadas por meio de modelos lineares generalizados, empregando-se a função de distribuição binomial e a função de ligação logística. As probabilidades de ocorrência de partos múltiplos foram calculadas por meio de um modelo que incluiu os efeitos de ano e mês de cobertura, ordem de parto, idade ao primeiro parto, peso à cobertura, produção de leite, duração da lactação e intervalo de partos. A prolificidade média do rebanho foi de 1,49 cabrito. Os efeitos de mês de cobertura, ordem de parto, peso na cobertura, idade ao primeiro parto e intervalo de partos foram significativos. As chances de partos múltiplos tenderam a aumentar com o avanço da idade da fêmea (ordem e do peso à cobrição. Fêmeas cobertas no período de disponibilidade de alimentos apresentaram maior probabilidade de partos múltiplos. A idade ao primeiro parto foi outra variável importante, pois fêmeas com maior idade apresentaram maior probabilidade de partos múltiplos. As fêmeas com maior intervalo de parto tenderam a apresentar maiores probabilidades de parir mais de uma cria. A prolificidade de caprinos mestiços é altamente afetada pela variação de ambiente, maturidade fisiológica, condição corporal e idade de início da vida reprodutiva.The aim of this study was to evaluate the influence of some environmental effects on the litter size, using 526 records of kidding of dairy crossbreed goats.

    Full Text Available Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, a protozoan with wide geographical distribution and minimal parasitic specificity that affects many species of wild and domestic animals. In livestock, especially in small ruminants like goats, toxoplasmosis can cause abortion and the birth of weak animals, leading to economic losses to farmers, and is a major source of human infection. This is a seroepidemiological study of toxoplasmosis in goats in the state of Paraná, Brazil. Sera from 405 goats from the metropolitan mesoregion of Curitiba, eastern state, were tested by the enzyme-linked immunosorbent assay (ELISA and indirect immunofluorescence antibody test (IFAT. Information on properties and goat characteristics was also collected using questionnaires. The prevalence of toxoplasmosis was 39.41 and 35.96% by ELISA and IFAT, respectively. T. gondii antibody prevalence increased with age. The risk factors for T. gondii infection in goats were: age over one year; exposure to cats, type of management and purpose of breeding. Other epidemiological factors and relevant control measures are discussed in the current study.A toxoplasmose é uma zoonose causada pelo Toxoplasma gondii, um protozoário com vasta distribuição geográfica e pouca especificidade parasitária, que pode afetar muitas espécies de animais selvagens e domésticos. Em animais de produção, especialmente pequenos ruminantes, como caprinos, pode provocar abortos e nascimento de crias fracas, causando perdas econômicas para os criadores, além de ser uma importante fonte de infecção humana.

    Full Text Available Goats, called “the cow of the poor”, are the livestock species with the most significant population growth worldwide in recent years. Gastrointestinal parasitism constitutes one of the main constraints to its outdoor and extensive breeding in temperate and tropical countries. Despite a Creole goat population of nearly 4 million heads, local reports on parasitological prevalence are scarce, and while Fasciola hepatica infection is spread all over Argentina, the goat is usually neglected as a reservoir and economic losses are not considered. To evaluate gastrointestinal parasitism prevalence and associations between parasite genera and species, with emphasis on fascioliasis, Creole goats from the plateau and Andean regions from western Argentina were investigated by coprological techniques, and associations were statistically assessed. Eighty-five percent (85% of the animals harbored one or more parasite types, while 46% showed mixed infections. Significant positive associations between F. hepatica + Strongyle eggs, Eimeria sp. + Nematodirus sp. and Nematodirus sp. + Trichuris ovis were detected. Further studies are required to define the causality of these associations and their relevance in epidemiology. F. hepatica is rarely considered as goat parasite in the country, but a 33% prevalence poses an interrogation on the role goats play on the transmission and dissemination of this zoonotic trematode.As cabras, nomeadas como “a vaca dos pobres”, são as espécies de gado com o crescimento populacional mais significativo nos últimos anos em todo o mundo. O parasitismo gastrintestinal constitui uma das principais limitações à sua criação extensiva em clima temperado e tropical. Na Argentina, apesar de uma população de caprinos crioulos de cerca de quatro milhões de cabeças, são escassos os relatórios locais de prevalências parasitológicas. Embora a infecção por Fasciola hepatica esteja espalhada em todo o país, as cabras s

As peles foram curtidas e recurtidas e dos couros retiraram-se três corpos-de-prova das regiões dorsal, paleta, ventral, anca e lateral, nas direções paralelas e perpendicular ao eixo crânio-caudal, para realização dos ensaios físico-mecânicos: distensão da "flor" no lastrômetro, rasgamento progressivo, resistência à tração, análises químicas de extração de lipídios, óxido de cromo, pH e cifra diferencial. A idade do animal exerceu efeito positivo no ensaio de resistência à tração, com superioridade para os caprinos de 315 dias de vida. A região e a posição em todos animais estudados apresentaram efeito significativo no ensaio de resistência ao rasgamento progressivo, nas quatro idades, atingindo o valor de referência mínima de 80 kgf/cm. A resistência do couro à distensão da "flor" dos caprinos estudados foi superior ao mínimo de 7 mm, demonstrando grande elasticidade dos couros, sem influência de idade ou região.This paper focuses on the analysis of goats leather to identify the physical and mechanical characteristics after toning.

    Full Text Available The serological response to an experimental vaccine against Clostridium perfringens type D enterotoxemia was evaluated in four groups of goats. Group 1 received colostrum from unvaccinated cows and no vaccine. Groups 2, 3 and 4 received colostrum from vaccinated cows. In addition, Groups 3 and 4 received a vaccine dose at 80 days of age, and Group 4 received a second vaccine dose at 120 days of age. Serum antibody levels were determined by ELISA in cows before and after calving, and in goats at 3, 80, 120 and 160 days of age. No significant difference in serum antibody levels was observed between vaccinated and unvaccinated cows, or between the four groups of goats evaluated at 3 days of life. Groups 3 and 4 presented mean antibody titers of 0.6 and 1.1 IU/ml, respectively, 40 days after first vaccination. The vaccine response of Group 4 was 1.8 IU/ml 40 days after the booster dose and was higher than that observed for Group 3 (0.2 IU/ml. Thus, in the proposed regimen the use of heterologous colostrum did not induce passive immunization in goat kids. However, first vaccination and a booster dose after 40 days triggered satisfactory antibody levels.Foi avaliada a resposta sorológica de vacina experimental contra a enterotoxemia em quatro grupos de caprinos. O Grupo 1 recebeu colostro de vacas não vacinadas e nenhuma dose de vacina. Os Grupos 2, 3 e 4 receberam colostro de vacas vacinadas, e uma dose de vacina aos 80 dias de idade nos Grupos 3 e 4. O Grupo 4 recebeu a segunda dose de vacina aos 120 dias de idade. Os níveis de anticorpos séricos foram avaliados pelo ELISA nas vacas antes e depois do parto e nos caprinos aos 3, 80, 120 e 160 dias de idade. Não houve diferença significativa nos níveis de anticorpos séricos das vacas vacinadas e não vacinadas, assim como entre os quatro grupos de caprinos avaliados aos três dias de vida.

    Full Text Available Phytotherapy may be an alternative strategy for controlling gastrointestinal parasites. This study evaluated the anthelmintic efficacy of Eucalyptus citriodora essential oil (EcEO. The in vitro effects of EcEO were determined through testing the inhibition of egg hatching and larval development of Haemonchus contortus. EcEO was subjected to acute toxicity testing on mice, orally and intraperitoneally. The in vivo effects of EcEO were determined by the fecal egg count reduction test (FECRT in goats infected with gastrointestinal nematodes. The results showed that 5.3 mg.mL-1 EcEO inhibited egg hatching by 98.8% and 10.6 mg.mL-1 EcEO inhibited H. contortus larval development by 99.71%. The lethal doses for 50% of the mice were 4153 and 622.8 mg.kg-1, for acute toxicity orally and intraperitoneally. In the FECRT, the efficacy of EcEO and ivermectin was 66.25 and 79.16% respectively, on goat gastrointestinal nematodes eight days after treatment.

    Full Text Available Com o objetivo de estudar o efeito da restrição alimentar sobre as características da carcaça de caprinos leiteiros, realizou-se um experimento utilizando 27 cabritos castrados da raça Saanen. Os animais (PV inicial de 20 kg foram distribuídos nos tratamentos alimentação à vontade e 30 e 60% de restrição, sendo abatidos aos 35 kg de PV. Foram avaliados o rendimento comercial e biológico, os cortes comerciais, a área de olho-de-lombo e a composição tecidual da perna. O rendimento biológico não foi afetado pela restrição alimentar, mas o comercial diminuiu com o aumento da restrição. A elevação no nível de restrição alimentar promoveu diminuição do lombo e da 6ª a 13ª costelas e aumento da paleta e do pescoço, proporcionalmente à meia-carcaça. A proporção de ossos aumentou e a de gordura total diminuiu com o aumento da restrição. O tecido muscular não foi afetado pela restrição. A restrição alimentar de até 30% não prejudicou a qualidade da carcaça de caprinos leiteiros.Twenty-seven Saanen male kids averaging 20 kg of body weight (BW at the beginning of the trial were used to study the effects of feed restriction on carcass characteristics. Animals were assigned to one of the following three treatments: control (fed ad libitum, 30 or 60% of feed restriction.

    Full Text Available Alterações oftálmicas foram experimentalmente induzidas em caprinos após superdosagem com o anti-helmíntico closantel. Foram usados cinco caprinos com sete a oito meses de idade, produtos do cruzamento da raça Saanen com a Pardo Alpino. Os animais mostraram sinais de intoxicação entre quatro e cinco dias após a administração do closantel. Os sinais clínicos caracterizaram-se principalmente por distúrbios neurológicos centrais e cegueira. Ao exame clínico, observaram-se midríase bilateral, perda do reflexo pupilar à luz e cegueira bilateral. À oftalmoscopia indireta, foram observadas degeneração aguda de retina e papiledema. As alterações crônicas mostravam disco óptico acinzentado, atrofia de vasos e da retina. Nos fundos tapetal e não-tapetal notavam-se áreas de despigmentação e lesões irregulares castanho-amareladas. As alterações histológicas consistiam em perda dos neurônios da camada ganglionar e das células da camada nuclear interna e externa da retina. As alterações agudas no nervo óptico e na substância branca do encéfalo foram de degeneração espongiforme. As alterações crônicas do nervo óptico caracterizavam-se por extensa necrose e infiltração de células Gitter.Ophthalmic alterations were experimentally induced after overdose with the anthelmintic closantel. Five seven to eight- months-old, Saanen x Alpine caprine were used. The animals showed clinical signs of toxicosis four to five days after the administration of closantel. Clinical signs were primarily characterized by central nervous disturbances and blindness. Clinically, bilateral mydriasis, loss of pupillary light reflex, and blindness were observed. At indirect ophthalmoscopic examination, there was acute retinal degeneration and papilledema. Chronic ocular changes consisted of paleness of the optic disc, vascular atrophy, and retinal atrophy. Areas of pigment loss and irregular yellowish-brown foci were present in the tapetal

    In this study we examined the influence of several factors, like the surface of skin with lesions attributable to Sarcoptes scabiei, the time of year and host sex and age on variations of mite load in Iberian wild goats, Capra pyrenaica, from the Sierra Nevada Natural Space, southern Spain. As well, the surface area of skin with scabietic lesions estimated during field surveys were compared with measurements taken in the laboratory and the potential for using categories based on surface areas estimated during monitoring and management programs was analyzed. The surface area of the skin lesions measured in the laboratory and the time of year were the main factors affecting mite load. Results also revealed discrepancies between the surface area of lesions estimated in the field and those measured in the laboratory. The highest error percentages were associated with lesions ranging between 25 and 75% of host skin surface area. By reducing the number of categories of mange infestation (from 5 to 3) the proportion of cases correctly classified using data from field surveys increases. Our analyses suggest that the estimated surface areas of scabietic lesions is a useful relative index of mite abundance and/or intensity of parasitation in Iberian wild goat. Therefore, we conclude that revised classifications should be used in the monitoring of sarcoptic mange in wild populations, since data can be obtained in an inexpensive, fast and non-invasive fashion.

It was used 40 castrated young goats, 20 from Moxotó breed and 20 from Canindé breed, each one with an average body weight of 15.2 kg. The animals were fed with diets containing 2.20 and 2.71 (Mcal/kg DM. The experimental period lasted 86 days. There was no difference among the barometric measures of Moxotó and Canindé kids. Canindé goats showed higher final weight, higher weight after fasting and higher hot and cold carcass weights when compared to the Moxotó animals. Animals that consumed diets with higher energy level had higher final weight and conformation as well as higher carcass yield. Considering the percentage values of the commercial meat cuts, no difference among treatments was observed. The diet was the factor that most influenced the non-constituent components of the carcass of Moxotó and Canindé goats. In general, animals belonging to the Canindé breed presented higher quantitative characteristics than the Moxotó breed. Supply of diets with higher energetic level (2.71 Mcal/kg DM for goats from Moxotó and Canindé breeds, in feedlots, favors the production of carcass with higher yields and heavier commercial meat cuts.Objetivou-se avaliar as características quantitativas da carcaça de caprinos Moxotó e Canindé terminados em confinamento e recebendo dietas com dois níveis de energia.

    Goats were among the first farm animals domesticated, ≈10,500 years ago, contributing to the rise of the “Neolithic revolution.” Previous genetic studies have revealed that contemporary domestic goats (Capra hircus) show far weaker intercontinental population structuring than other livestock species, suggesting that goats have been transported more extensively. However, the timing of these extensive movements in goats remains unknown. To address this question, we analyzed mtDNA sequences from...

    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

    Full Text Available Abstract Background Hybridization between closely related wild and domestic species is of great concern because it can alter the evolutionary integrity of the affected populations. The high allelic variability of Major Histocompatibility Complex (MHC loci usually excludes them from being used in studies to detect hybridization events. However, if a the parental species don’t share alleles, and b one of the parental species possesses an exceptionally low number of alleles (to facilitate analysis, then even MHC loci have the potential to detect hybrids. Results By genotyping the exon2 of the MHC class II DRB1 locus, we were able to detect hybridization between domestic goats (Capra hircus and free-ranging Iberian ibex (Capra pyrenaica hispanica by molecular means. Conclusions This is the first documentation of a Capra pyrenaica × Capra hircus hybridization, which presented us the opportunity to test the applicability of MHC loci as new, simple, cost-effective, and time-saving approach to detect hybridization between wild species and their domesticated relatives, thus adding value to MHC genes role in animal conservation and management.

    Full Text Available This study was conducted in order to verify the effect of different concentrations of BMP-7 in the in vitro survival and development of caprine preantral follicles. Fragments of caprine ovarian cortical tissue were cultured for 1 or 7 days in Minimum Essential Medium (MEM+ supplemented with different concentrations of BMP-7 (1, 10, 50 or 100ng/ml. Non-cultured fragments or those cultured for 1 or 7 days were processed for classical histology and transmission electron microscopy (TEM. Parameters such as follicular survival, activation and growth were evaluated. The results showed that, after 1 or 7 days of culture, the percentage of morphologically normal follicles was significantly reduced in all treatments when compared with fresh control, except at 1ng/ml of BMP-7 for 1 day. In addition, the concentration of 10ng/ml of BMP-7 significantly increases follicular diameter from day 1 to 7 of culture. There was no influence of the other concentrations of BMP-7 regarding to the follicular and oocyte diameter. Ultrastructure studies confirmed follicular integrity after 7 days of culture in 1ng/ml BMP-7. In conclusion, small concentrations of BMP-7 can improve the survival and growth of caprine preantral follicles during in vitro culture.O presente trabalho foi conduzido de modo a se verificar o efeito de diferentes concentrações da BMP-7 no desenvolvimento in vitro de folículos pré-antrais caprinos.

Em 5 surtos os animais eram suplementados com concentrados e em 5 consumiam somente pastagem. Em um dos surtos os ovinos estavam recebendo à vontade uma mistura múltipla contendo 1,3% de flor de enxofre. Os sinais clínicos caracterizaram-se por cegueira, depressão, pressão da cabeça contra objetos, andar em círculos, ranger de dentes, incoordenação, paralisia espástica, ataxia, diminuição dos reflexos palpebral e pupilar, estrabismo lateral, nistagmo e pupilas dilatadas. De 9 animais tratados com tiamina e dexametasona, 7 se recuperaram e 2 morreram. O diagnóstico foi feito com base na recuperação após o tratamento e/ou a presença de alterações histológicas características. O curso clínico variou de 2 a 15 dias. Três animais foram necropsiados. Um animal apresentou herniação do cerebelo em direção ao Forame magno e amolecimento das circunvoluções cerebrais e, ao corte, coloração amarelada e cavitação da substância cinzenta do córtex. Outro animal apresentou somente herniação do cerebelo. No terceiro animal não foram observadas lesões macroscópicas.

Foram utilizadas 18 cabras e suas respectivas crias, num total de 33 animais. A coleta de sangue das cabras foi iniciada 45 dias antes da data prevista para o parto e foi realizada em intervalos de cinco dias até o 5º dia após o parto. Os cabritos foram distribuídos em dois grupos: um grupo recebeu colostro caprino e o outro colostro bovino. As coletas de sangue foram feitas às 0, 12, 24 e 48 horas e aos 5, 10, 15, 17, 20, 25, 30, 35, 40, 50 e 60 dias de vida. Foram analisadas as concentrações séricas de proteína total e imunoglobulinas, além da concentração de imunoglobinas no colostro. O delineamento experimental foi o inteiramente casualizado e as variáveis séricas analisadas como medidas repetidas. A ausência de queda na concentração sérica de proteínas totais e imunoglobinas no período pré-parto indica que a mobilização de anticorpos para glândula mamária ocorre em concentrações que permitem o animal manter essas variáveis sem grandes alterações. No grupo que recebeu colostro bovino, a data de concentração máxima de proteínas totais (7,16 ± 0,28 g/dL foi verificada às 48,68 ± 0,70 horas de vida e a de imunoglobinas, às 48,75 ± 0,73 horas, com média de 37,56 ± 2,38 unidades ZST (turvação por sulfato de zinco.

    Full Text Available INTRODUCTION: Goats are considered very susceptible to infection by Toxoplasma gondii and when this occurs during pregnancy, it may cause fetal death with subsequent fetal resorption, abortion, mummification, stillborn or the birth of weak goats. The objective of this work was to determine the occurrence of and identify risk factors for T. gondii infection in goats in different mesoregions in the State of Alagoas. METHODS: The research was conducted on 24 goat breeding farms in 10 municipalities. A total of 454 blood samples were examined for anti-T. gondii antibodies by indirect immunofluorescence antibody test. To evaluate the risk factors of toxoplasmosis in goats, questionnaires were applied analyzing the farm's production system and nutritional, reproductive and sanitary management. RESULTS: Disease occurrence was 39% with 95.8% of farms presenting seropositive animals. Significant associations were observed for mesoregion (OR = 0.23; 95%CI = 0.09 - 0.57, age (OR = 0.36; 95%CI = 0.20 - 0.64, semi-intensive herd management (OR = 8.70; 95%CI = 1.87 - 40.43, access of cats to water provided for goats (OR = 3.38; 95%CI = 1.89-6.02 and cats feeding on placental remnants (OR = 2.73; 95%CI = 1.38 - 5.40.

    American trypanosomiasis is a chronic disease transmitted mainly by vectors. The hematophagous triatomine vectors transmit Trypanosoma cruzi to a wide variety of mammals, which usually are their food source. This study determined the feeding profile of Mepraia spinolai, a sylvatic triatomine vector, present in endemic areas of Chile. Vectors were captured in the north-central area of Chile. Samples of intestinal contents were analyzed by an Enzyme-linked immunosorbent assay (ELISA) that identifies and discriminates the presence of serum antigens from Homo sapiens and nine animal species (Canis familiaris, Felis catus, Capra hircus, Mus musculus, Gallus gallus, Octodon degus, Thylamys elegans, Phyllotis darwini and Oryctolagus cuniculus). Our data indicate the most frequent feeding source in this area was P. darwini, followed by O. degus, O. cuniculus, M. musculus, G. gallus, T. elegans, C. familiaris, F. catus and C. hircus. Mixed food sources were also identified. PMID:27349188

    Full Text Available This study investigated the levels of messenger ribonucleic acids (mRNA for inhibin-ßA subunit in goat primordial, primary and secondary follicles, as well as in cumulus-oocyte complexes (COCs and mural granulosa / theca cells of antral follicles. The effects of activin-A (100ng mL-1 and/or follicle stimulating hormone (FSH, 50ng mL-1 on growth and expression of mRNA for activin-A and FSH receptor (FSH-R in secondary follicles cultured for six days were evaluated. The data showed that the expression of inhibin-ßA is lower in secondary follicles than in primary follicles and is higher in large antral follicles than in small antral follicles. After culture, activin-A and/or FSH promoted growth of secondary follicles, while FSH increased the levels of mRNA for inhibin-ßA, and activin-A increased the levels of FSH-R mRNA. In conclusion, mRNA for inhibin-ßA is expressed at different levels in pre-antral and antral follicles and activin-A acts as a stimulator of the FSH-R expression in goat follicles. On its turn, the expression of inhibin-ßA is stimulated by FSH, which together with activin-A promotes secondary follicle growth in-vitro.Este estudo investigou os níveis de ácidos ribonucleicos (RNAm para a subunidade ßA da inibina em folículos primordiais, primários e secundários caprinos, bem como em complexos cumulus-oócitos (CCOs e células da granulosa mural/teca de folículos antrais.

    Full Text Available O uso de medicamentos antimamíticos específicos para vacas no período seco é indicado para prevenção de infecções na lactação seguinte. Não obstante, a ação das células envolvidas no período de secagem tem fundamental importância para a involução da glândula mamária e seu restabelecimento para a lactação subseqüente. A indisponibilidade de tais medicamentos para uso em cabras tem resultado na extrapolação do uso de produtos recomendados para vacas sem que se considerem as particularidades e diferenças anátomo-fisiológicas entre as espécies bovina e caprina.

    subsistence.El trabajo analiza la situación de conflicto que se presenta en las tierras secas de Mendoza, entre productores caprinos y programas de lucha contra la desertificación, a propósito de las prácticas productivas y el uso de los recursos naturales.Se aborda un caso de estudio situado en el extremo noreste de la provincia de Mendoza, polo hiperárido de la región, gravemente afectado por procesos de desertificación, con una extensión de 10.007km2 y poblado por 3015 habitantes, donde dominan las pequeñas explotaciones caprinas. Estudios previos señalan que las principales causas de la desertificación de la zona son la tala de bosque nativo y el sobrepastoreo que ocasionan las inadecuadas prácticas de producción ganadera. En respuesta a ello, las acciones de lucha contra la desertificación se orientan a "concientizar" y "capacitar" a los productores e impulsan procesos de cambio productivo. Las propuestas en curso insisten en que, de mantenerse los actuales niveles de presión sobre los recursos, en el futuro se amplificarán las ya graves condiciones de pobreza y desertificación. Sin embargo, a pesar de los esfuerzos y fondos invertidos los productores parecen obstinados en sus actuales estrategias de producción y en la dinámica de uso de los recursos naturales que de ellas derivan. ¿Cómo explicar que no tomen otras opciones productivas que impliquen mayores beneficios económicos y mejores equilibrios ambientales? ¿Cómo explicar que actúen, al menos en apariencia, en contra de sus propios beneficios? Haciendo crítica de las explicaciones que ubican en el epicentro del problema "la cultura" de los productores, este trabajo busca realizar un aporte a través del análisis de tres dimensiones: 1- La oferta ambiental que es soporte de las actividades productivas, 2- Los ingresos que las unidades de producción alcanzan y 3- Los egresos que enfrentan en concepto de subsistencia.

    Full Text Available Microsatellites or simple sequence repeats (SSRs have become the most popular source of genetic markers, which are ubiquitously distributed in many eukaryotic and prokaryotic genomes. This is the first study examining and comparing SSRs in completely sequenced genomes of the Bovidae. We analyzed and compared the number of SSRs, relative abundance, relative density, guanine-cytosine (GC content and proportion of SSRs in six taxonomically different bovid species: Bos taurus, Bubalus bubalis, Bos mutus, Ovis aries, Capra hircus, and Pantholops hodgsonii. Our analysis revealed that, based on our search criteria, the total number of perfect SSRs found ranged from 663,079 to 806,907 and covered from 0.44% to 0.48% of the bovid genomes. Relative abundance and density of SSRs in these Bovinae genomes were non-significantly correlated with genome size (Pearson, r 0.05. Perfect mononucleotide SSRs were the most abundant, followed by the pattern: perfect di- > tri- > penta- > tetra- > hexanucleotide SSRs. Generally, the number of SSRs, relative abundance, and relative density of SSRs decreased as the motif repeat length increased in each species of Bovidae. The most GC-content was in trinucleotide SSRs and the least was in the mononucleotide SSRs in the six bovid genomes. The GC-contents of tri- and pentanucleotide SSRs showed a great deal of similarity among different chromosomes of B. taurus, O. aries, and C. hircus. SSR number of all chromosomes in the B. taurus, O.aries, and C. hircus is closely positively correlated with chromosome sequence size (Pearson, r > 0.980, p 0.05. Relative abundances of the same nucleotide SSR type showed great similarity among different chromosomes of B. taurus, O. aries, and C. hircus.

    A method for cryopreserving wild ibex sperm at high cooling rates was developed. To design a freezing solution based on Tris, citric acid, and glucose (TCG), two preliminary experiments were performed using glycerol (GLY) and dimethyl sulfoxide (DMSO) at different concentrations (5%, 10%, 20%). The 10% GLY + 10% DMSO combination reduced (P TCG egg yolk (ey)-based extender with 100-mM sucrose, either alone or with 5% GLY with or without BSA. Two warming procedures (37 °C vs. 60 °C) were also evaluated. The TCG ey with 100-mM sucrose but without GLY/BSA returned the best sperm quality variables. Slow warming at 37 °C strongly affected (P TCG-ey + 100 mM sucrose), with warming undertaken at 60 °C. Inseminations of domestic goats resulted in three pregnancies (3 of 16, 18.7% fertility). In conclusion, ibex spermatozoa are strongly sensitive to high concentrations of permeable cryoprotectants and sucrose. However, the combination of ultrarapid cooling, using TCG-ey + 100-mM sucrose, and fast warming at 60 °C, followed by sperm selection by density gradient centrifugation to collect the motile sperm, has a positive effect on sperm viability.

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.

    We used the gut contents of triatomines collected from rural areas of Ceará State, northeastern Brazil, to identify their putative hosts via vertebrate cytb gene sequencing. Successful direct sequencing was obtained for 48% of insects, comprising 50 Triatoma brasiliensis, 7 Triatoma pseudomaculata, and 1 Rhodnius nasutus. Basic local alignment search tool (BLAST) procedure revealed that domestic animals, such as chickens (Gallus gallus) and goats (Capra hircus), are the main food source, including in sylvatic environment. Native hosts were also detected in peridomestic environment such as reptiles (Tropidurus sp. and Iguana iguana) and the Galea spixii (Rodentia: Caviidae). The role of goats and Galea spixii in Chagas disease epidemiology calls for further studies, because these mammals likely link the sylvatic and domestic Trypanosoma cruzi cycles. PMID:26350453

The mitogenome is 16,640 nt in length, consisting of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes and a control region. As in other mammals, most mitochondrial genes are encoded on the heavy strand, except for ND6 and eight tRNA genes, which are encoded on the light strand. Its overall base composition is A: 33.5%, T: 27.3%, C: 26.1% and G: 13.1%. The complete mitogenome of the local subspecies of Hechuan white goat could provide an important data to further breed improvement and animal genetics resource conservation in China. PMID:26702472

    To detect goat vascular endothelial growth factor (VEGF)-mediated regrowth of hair, full-length VEGF164 cDNA was cloned from Inner Mongolia cashmere goat (Capra hircus) into the pET-his prokaryotic expression vector, and the recombinant plasmid was transferred into E. coli BL21 cells. The expression of recombinant 6×his-gVEGF164 protein was induced by 0.5 mM isopropyl thio-β-D-galactoside at 32°C. Recombinant goat VEGF164 (rgVEGF164) was purified and identi ed by western blot using monoclonal anti-his and anti-VEGF antibodies. The rgVEGF164 was smeared onto the dorsal area of a shaved mouse, and we noted that hair regrowth in this area was faster than in the control group. Thus, rgVEGF164 increases hair growth in mice.

Assessment of BLLs of white Fulani cattle(Bos primigenius indicusand red Sokoto goats (Capra aegagrus hircus grazed freely on open pastures in Zaria was carried out by Atomic Absorption Spectrophotometry using Shimadzu Atomic Absorption Spectrophotometer (model AA-6800, Japan after wet digestion to evaluate the potential effects of the metal on the animals, the toxicological implication of consuming this major source of animal protein by humans and most importantly as an indirect measure of the lead pollution status of Zaria ecological geochemical environment. The blood lead levels of Bos primigenius indicus ranged from a minimum of 0.62 mg/l to a maximum of 2.28 mg/l with a mean value of 1.36±0.48 mg/l. On the other hand, blood lead levels of Capra aegagrus hircus ranged between 0.26 mg/l and 1.56 mg/l with a mean value of 0.89±0.43mg/l. The BLLs of both cows and goats were found to exceed the allowable limit for the elements in blood of food animals indicating that cows and goats grazed freely on open pastures in Zaria metropolis are not safe for human consumption. Routine monitoring of the heavy metal in plant and animal products is therefore recommended to safeguard human health. Most importantly, the study indicates the presence of elevated levels of environmental lead in Zaria ecological geochemical environment.

    Full Text Available Human population expansion and associated degradation of the habitat of many wildlife species cause loss of biodiversity and species extinctions. The small Simen Mountains National Park in Ethiopia is one of the last strongholds for the preservation of a number of afro-alpine mammals, plants and birds, and it is home to the rare endemic Walia ibex, Capra walie. The narrow distribution range of this species as well as potential competition for resources with livestock, especially with domestic goat, Capra hircus, may compromise its future survival. Based on a curated afro-alpine taxonomic reference library constructed for plant taxon identification, we investigated the diet of the Walia ibex and addressed the dietary overlap with domestic goat using DNA metabarcoding of faecal samples. Faeces of both species were collected from different localities in the National Park. We show that both species are browsers, with forbs, shrubs and trees comprising the largest proportion of their diet, supplemented by grasses. There was a considerable overlap in dietary preferences. Several of the preferred diet items of the Walia ibex (Alchemilla sp., Hypericum revolutum, Erica arborea and Rumex sp. were also among the most preferred diet items of the domestic goat. These results indicate that there is potential for competition between the two species, especially during the dry season, when resources are limited. Our findings, in combination with the expected increase in domestic herbivores, suggest that management plans should consider the potential threat posed by domestic goats to ensure future survival of the endangered Walia ibex.

    Comparative morphological, biometrical and molecular studies of Trichuris discolor isolated from Bos taurus from Spain and Iran was carried out. Furthermore, Trichuris ovis isolated from B. taurus and Capra hircus from Spain has been, molecularly, analyzed. Morphological studies revealed clear differences between T. ovis and T. discolor isolated from B. taurus but differences were not observed between populations of T. discolor isolated from different geographical regions. Nevertheless, the molecular studies based on the amplification and sequencing of the internal transcribed spacers 1 and 2 ribosomal DNA and 16S partial gene mitochondrial DNA showed clear differences between both populations of T. discolor from Spain and Iran suggesting two cryptic species. Phylogenetic studies corroborated these data. Thus, phylogenetic trees based on ITS1, ITS2 and 16S partial gene sequences showed that individuals of T. discolor from B. taurus from Iran clustered together and separated, with high bootstrap values, of T. discolor isolated from B. taurus from Spain, while populations of T. ovis from B. taurus and C. hircus from Spain clustered together but separated with high bootstrap values of both populations of T. discolor. Furthermore, a comparative phylogenetic study has been carried out with the ITS1and ITS2 sequences of Trichuris species from different hosts. Three clades were observed: the first clustered all the species of Trichuris parasitizing herbivores (T. discolor, T. ovis, Trichuris leporis and Trichuris skrjabini), the second clustered all the species of Trichuris parasitizing omnivores (Trichuris trichiura and Trichuris suis) and finally, the third clustered species of Trichuris parasitizing carnivores (Trichuris muris, Trichuris arvicolae and Trichuris vulpis).

    Two experiments have been performed to clone the bucardo, an extinct wild goat. The karyoplasts were thawed fibroblasts derived from skin biopsies, obtained and cryopreserved in 1999 from the last living specimen, a female, which died in 2000. Cytoplasts were mature oocytes collected from the oviducts of superovulated domestic goats. Oocytes were enucleated and coupled to bucardo's fibroblasts by electrofusion. Reconstructed embryos were cultured for 36h or 7d and transferred to either Spanish ibex or hybrid (Spanish ibex malex domestic goat) synchronized recipients. Embryos were placed, according to their developmental stage, into the oviduct or into the uterine horn ipsilateral to an ovulated ovary. Pregnancy was monitored through their plasmatic PAG levels. In Experiment 1, 285 embryos were reconstructed and 30 of them were transferred at the 3- to 6-cells stage to 5 recipients. The remaining embryos were further cultured to day 7, and 24 of them transferred at compact morula/blastocyst stage to 8 recipients. In Experiment 2, 154 reconstructed embryos were transferred to 44 recipients at the 3- to 6-cells stage. Pregnancies were attained in 0/8 and 7/49 of the uterine and oviduct-transferred recipients, respectively. One recipient maintained pregnancy to term, displaying very high PAG levels. One morphologically normal bucardo female was obtained by caesarean section. The newborn died some minutes after birth due to physical defects in lungs. Nuclear DNA confirmed that the clone was genetically identical to the bucardo's donor cells. To our knowledge, this is the first animal born from an extinct subspecies. PMID:19167744

    Host-parasite relationships have been frequently investigated in mountain dwelling ungulates, though mostly focusing on gastrointestinal nematodes. On the contrary, very few studies were conducted on broncopulmonary nematodes, which may result in severe parenchymal lesions and act as predisposing factor for multifactorial pneumonia. The epidemiological and ecological features of lungworms infecting an Alpine ibex population in the Eastern Alps, Italy, were non-invasively investigated by means of a modified Baermann technique with an original quantitative methodology. Out of a total of 269 samples collected monthly from July to November 2013 and from July to October 2014, 212 (78.8%) were positive for Muellerius and 26 (9.7%) for Protostrongylus, whereas Neostrongylus and Cystocaulus were less prevalent (4.1% and 0.7%, respectively). None of the investigated samples tested positive for dictyocaulids. The genus Muellerius showed the highest larval output intensity (134.2 L1/g), followed by Protostrongylus with 33.8 L1/g. A contrasting age-related pattern of Muellerius and Protostrongylus was revealed, with the former significantly more prevalent and abundant in adult animals, while the latter in kids. Due to the limited accessibility of the study area during winter and spring, it was difficult to describe clear seasonal trends in larval output, although Muellerius showed a minimum in the late summer and a rise in the autumn. The newly developed diagnostic method showed a fair repeatability, thus representing an interesting tool to investigate the ecology of lungworms in protected species, such as the A. ibex. Based on results, ibex in the Marmolada massif seem to have an ecologically stable relationship with their lungworm community. PMID:26476915

  10. Introgression from domestic goat generated variation at the major histocompatibility complex of Alpine ibex.

    Full Text Available The major histocompatibility complex (MHC is a crucial component of the vertebrate immune system and shows extremely high levels of genetic polymorphism. The extraordinary genetic variation is thought to be ancient polymorphisms maintained by balancing selection. However, introgression from related species was recently proposed as an additional mechanism. Here we provide evidence for introgression at the MHC in Alpine ibex (Capra ibex ibex. At a usually very polymorphic MHC exon involved in pathogen recognition (DRB exon 2, Alpine ibex carried only two alleles. We found that one of these DRB alleles is identical to a DRB allele of domestic goats (Capra aegagrus hircus. We sequenced 2489 bp of the coding and non-coding regions of the DRB gene and found that Alpine ibex homozygous for the goat-type DRB exon 2 allele showed nearly identical sequences (99.8% to a breed of domestic goats. Using Sanger and RAD sequencing, microsatellite and SNP chip data, we show that the chromosomal region containing the goat-type DRB allele has a signature of recent introgression in Alpine ibex. A region of approximately 750 kb including the DRB locus showed high rates of heterozygosity in individuals carrying one copy of the goat-type DRB allele. These individuals shared SNP alleles both with domestic goats and other Alpine ibex. In a survey of four Alpine ibex populations, we found that the region surrounding the DRB allele shows strong linkage disequilibria, strong sequence clustering and low diversity among haplotypes carrying the goat-type allele. Introgression at the MHC is likely adaptive and introgression critically increased MHC DRB diversity in the genetically impoverished Alpine ibex. Our finding contradicts the long-standing view that genetic variability at the MHC is solely a consequence of ancient trans-species polymorphism. Introgression is likely an underappreciated source of genetic diversity at the MHC and other loci under balancing selection.

    We have developed a fully enzyme-free SERRS hybridization assay for specific detection of double-stranded DNA sequences. Although all DNA detection methods ranging from PCR to high-throughput sequencing rely on enzymes, this method is unique for being totally non-enzymatic. The efficiency of enzymatic processes is affected by alterations, modifications, and/or quality of DNA. For instance, a limitation of most DNA polymerases is their inability to process DNA damaged by blocking lesions. As a result, enzymatic amplification and sequencing of degraded DNA often fail. In this study we succeeded in detecting and quantifying, within a mixture, relative amounts of closely related double-stranded DNA sequences from Rupicapra rupicapra (chamois) and Capra hircus (goat). The non-enzymatic SERRS assay presented here is the corner stone of a promising approach to overcome the failure of DNA polymerase when DNA is too degraded or when the concentration of polymerase inhibitors is too high. It is the first time double-stranded DNA has been detected with a truly non-enzymatic SERRS-based method. This non-enzymatic, inexpensive, rapid assay is therefore a breakthrough in nucleic acid detection. PMID:22695500

    Full Text Available Abstract Currently, the assessment of sperm function in a raw or processed semen sample is not able to reliably predict sperm ability to withstand freezing and thawing procedures and in vivo fertility and/or assisted reproductive biotechnologies (ART outcome. The aim of the present study was to investigate which parameters among a battery of analyses could predict subsequent spermatozoa in vitro fertilization ability and hence blastocyst output in a goat model. Ejaculates were obtained by artificial vagina from 3 adult goats (Capra hircus aged 2 years (A, B and C. In order to assess the predictive value of viability, computer assisted sperm analyzer (CASA motility parameters and ATP intracellular concentration before and after thawing and of DNA integrity after thawing on subsequent embryo output after an in vitro fertility test, a logistic regression analysis was used. Individual differences in semen parameters were evident for semen viability after thawing and DNA integrity. Results of IVF test showed that spermatozoa collected from A and B lead to higher cleavage rates (0

    Full Text Available During the underwater excavations carried out in the Santa Giusta Pond, near Oristano, Sardinia, a significant amount of Phoenician- Punic materials was brought to light including amphorae (dating back to 7th-2nd century BC and vegetal and animal remains. All of these archaeological finds may come from Othoca, an important Phoenician- Punic city on the eastern shore of the pond, geographically corresponding with the modern-day town of Santa Giusta. Animal materials consist of more than 3000 very well-preserved remains, belonging to sheep (Ovis aries, goat (Capra hircus and cattle (Bos taurus. Bone analyses allowed reconstructing the slaughtering methods, as well as manipulation procedures carried out to preserve meat in order to be exported overseas. Although pig (Sus scrofa played an important economical role in other Sardinian Phoenician-Punic settlements, in this archaeological context this species is absent, suggesting that the meat contained in the amphorae was probably destined to other areas of the Mediterranean basin, where people did not eat pork.

    Full Text Available Meat adulterations of different species are undetectable and it is common practice globally. In the field of food analysis, species determination is mostly sufficient, but simultaneous detection of several species in a single food product is desirable. The aim of the study was to distinguish between meats of two different species through PCR-RFLP analysis. The meat of two species were used include domestic pig (Sus scrofa; Porcidae and domestic goat (Capra hircus; Bovidae. DNA was isolated from these samples , followed by amplification through PCR and further species was differentiated by RFLP using five different restriction endonuclease (RE enzymes. The DNA sequences of different species are different, hence does not digest by same enzyme. The number and position of bands obtained after digestion were different in two species. In case of meat adulteration, the specific number and position of bands of DNA of a particular species will not be obtained, rather bands will be formed at intermediate positions and number of bands may vary. Thus, PCR-RFLP method is a potential tool for forensic identification and to differentiate specific meat sample and this molecular technique is an important tool to examine adulteration in meat food products.

  15. Detection and classification of Trypanosoma cruzi genotypes in animals of an endemic area of Chile

    International Nuclear Information System (INIS)

    Blood samples from 200 sylvatic and peridomestic animals from an endemic area of Chile were subjected to PCR amplification of Trypanosoma cruzi minicircle sequences. This method enabled to detect parasite DNA in animals of the species. (Thylamis elegans, Octodon degus, Phyllotis darwini, and Abrothrix olivaceuss) as representatives of sylvatic animals, and Capra hircus as representative of the peridomestic one. Altogether, 51% of the sylvatic and 36% of the peridomestic animals were infected with T.cruzi Amplified DNA products obtained in this study were then studied by Southern analysis with a panel of four radioactive probes prepared from genotyped T.cruzi clones in the endemic areas of Chile and pertaining to T.cruzi lineages I and II. Most of the animal are infected at a rate of 35% with T.cruzi I, however other 85% are infected with T.cruzi II. This method is able to detect mixed infections with two or more different genotypes this figure raise to approximately 40% in this sample. (author)

  16. Goats favour personal over social information in an experimental foraging task

    Full Text Available Animals can use their environments more efficiently by selecting particular sources of information (personal or social, according to specific situations. Group-living animals may benefit from gaining information based on the behaviour of other individuals. Indeed, social information is assumed to be faster and less costly to use than personal information, thus increasing foraging efficiency. However, when food sources change seasonally or are randomly distributed, individual information may become more reliable than social information. The aim of this study was to test the use of conflicting personal versus social information in goats (Capra hircus, in a foraging task. We found that goats relied more on personal than social information, when both types of information were available and in conflict. No effect of social rank was found on the occasions when goats followed other demonstrator goats. Goats are selective browsers/grazers and therefore relying on personal rather than social information could be the most efficient way to find patchily distributed resources in highly variable environments. Studies testing specific assumptions regarding the use of different sources of information can extend our understanding of decision making, including observed patterns of social learning.

    Goats were among the first farm animals domesticated, approximately 10,500 years ago, contributing to the rise of the "Neolithic revolution." Previous genetic studies have revealed that contemporary domestic goats (Capra hircus) show far weaker intercontinental population structuring than other livestock species, suggesting that goats have been transported more extensively. However, the timing of these extensive movements in goats remains unknown. To address this question, we analyzed mtDNA sequences from 19 ancient goat bones (7,300-6,900 years old) from one of the earliest Neolithic sites in southwestern Europe. Phylogenetic analysis revealed that two highly divergent goat lineages coexisted in each of the two Early Neolithic layers of this site. This finding indicates that high mtDNA diversity was already present >7,000 years ago in European goats, far from their areas of initial domestication in the Near East. These results argue for substantial gene flow among goat populations dating back to the early neolithisation of Europe and for a dual domestication scenario in the Near East, with two independent but essentially contemporary origins (of both A and C domestic lineages) and several more remote and/or later origins.

    SOX proteins constitute a large family of diverse, well-conserved transcription factors present in vertebrates and invertebrates, and also implicated in control of many developmental processes. Our objectives have been to identify Sox14 gene of goat (Capra hircus), cow (Bos taurus) and rat (Rattus norvegicus), and to perform comparative analyses and mapping of SOX14 orthologues from numerous vertebrate species. PCR based approach was used to identify Sox14 of goat, cow and rat, while nucleotide and amino acid sequence alignments and mapping were performed using information currently available in public database. Comparative sequence analysis revealed remarkable identity among Sox14 orthologues and helped us to identify highly conserved motifs that represent molecular signatures of SOX14 protein that might have structural or functional significance. Further, we determined chromosomal locations of numerous predicted group B Sox genes and their neighbouring genes using currently available genome database. In conclusion, our study has not only supported the proposed model of group B Sox genes evolution in chicken and mammals, but has also revealed that additional evolutionary events split Sox B genes into different chromosomes in some mammals. Mapping data presented in this study could help in refining the understanding of the evolution of group B Sox genes in vertebrates.

    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.

  1. Domestication process of the goat revealed by an analysis of the nearly complete mitochondrial protein-encoding genes.

    Directory of Open Access Journals (Sweden)

    Koh Nomura

    Full Text Available Goats (Capra hircus are one of the oldest domesticated species, and they are kept all over the world as an essential resource for meat, milk, and fiber. Although recent archeological and molecular biological studies suggested that they originated in West Asia, their domestication processes such as the timing of population expansion and the dynamics of their selection pressures are little known. With the aim of addressing these issues, the nearly complete mitochondrial protein-encoding genes were determined from East, Southeast, and South Asian populations. Our coalescent time estimations suggest that the timing of their major population expansions was in the Late Pleistocene and significantly predates the beginning of their domestication in the Neolithic era (≈10,000 years ago. The ω (ratio of non-synonymous rate/synonymous substitution rate for each lineage was also estimated. We found that the ω of the globally distributed haplogroup A which is inherited by more than 90% of goats examined, turned out to be extremely low, suggesting that they are under severe selection pressure probably due to their large population size. Conversely, the ω of the Asian-specific haplogroup B inherited by about 5% of goats was relatively high. Although recent molecular studies suggest that domestication of animals may tend to relax selective constraints, the opposite pattern observed in our goat mitochondrial genome data indicates the process of domestication is more complex than may be presently appreciated and cannot be explained only by a simple relaxation model.

    The safety of the SAG2 virus, a low virulence mutant of the SAD strain, was investigated in ten species of mammals and seven species of birds liable to consume vaccine baits. These species are the western hedgehog (Erinaceus europaeus), the meadow vole (Microtus arvalis), the bank vole (Clethrionomys glareolus), the water vole (Arvicola terrestris), the field mouse (Apodemus flavicollis or A. sylvaticus), the Norway rat (Rattus norvegicus), the european badger (Meles meles), the domestic ferret (Mustela putorius furo), the wild boar (Sus scrofa), the domestic goat (Capra hircus), the carrion crow (Corvus corone), the rook (Corvus frugilegus), the buzzard (Buteo buteo), the red kite (Milvus milvus), the tawny owl (Strix aluco), the long-eared owl (Asio otus) and the barn owl (Tyto alba). The vaccine was administered orally to each species, by an intramuscular (i.m.) route to the rodents and ferret, and by an intracerebral route to the field mouse. No pathogenicity was observed in the 169 animals vaccinated throughout an observation period of over 30 days. After euthanasia, no rabies virus could be detected either in the brain or in the salivary glands of any of the animals. The SAG2 virus administered orally, triggered a specific seroconversion in the field mouse, wild boar, ferret and most of the raptors. Following administration by the i.m. route, specific antibody titres were observed in most of the rodents, as well as in the ferrets. PMID:9014291

    A total of 415 adult domesticated ruminants, 130 cattle (Bos taurus), 108 buffaloes (Bubalus bubalis), 94 goats (Capra hircus) and 83 sheep (Ovis aries) inhabiting tribal rural areas of southern Rajasthan, India were investigated for evidence of gastrointestinal protozoan and helminthic infections. In southern Rajasthan humid ecosystem is predominant and has number of perennial freshwater bodies. Fresh faecal samples of these animals were examined microscopically by direct wet smear with saline and 1 % Lugol's iodine and formalin ether concentration. Of these 296 (71.32 %) were found to be infected with different species of gastrointestinal parasites. The highest (93.84 %) prevalence of these parasitic infections was found in cattle followed by goats (82.97 %), sheep (55.42 %) and buffaloes (46.29 %). Except cattle no other ruminants revealed protozoan infection. A total 8 species of gastrointestinal parasites were encountered. Among these parasites Fasciola hepatica was the commonest (15.18 %) followed by Haemonchus contortus (11.32 %), Ancylostoma duodenale (10.36 %), Trichuris trichiura (9.15 %), Amphistome species (7.95 %), Moniezia expansa (6.98 %), Strongyloides stercoralis (4.57 %) and Balantidium coli (3.37 %). The prevalence rate of these parasitic infections also varied seasonally. The highest prevalence rate was found in rainy season (84.21 %) followed by winter (73.9 %) and summer (52.8 %). The possible causes for variation in prevalence of parasitic infections are also discussed. PMID:24431582

    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.

    Advances in wildlife telemetry and remote sensing technology facilitate studies of broad-scale movements of ungulates in relation to phenological shifts in vegetation. In tropical island dry landscapes, home range use and movements of non-native feral goats (Capra hircus) are largely unknown, yet this information is important to help guide the conservation and restoration of some of the world's most critically endangered ecosystems. We hypothesized that feral goats would respond to resource pulses in vegetation by traveling to areas of recent green-up. To address this hypothesis, we fitted six male and seven female feral goats with Global Positioning System (GPS) collars equipped with an Argos satellite upload link to examine goat movements in relation to the plant phenology using the Normalized Difference Vegetation Index (NDVI). Movement patterns of 50% of males and 40% of females suggested conditional movement between non-overlapping home ranges throughout the year. A shift in NDVI values corresponded with movement between primary and secondary ranges of goats that exhibited long-distance movement, suggesting that vegetation phenology as captured by NDVI is a good indicator of the habitat and movement patterns of feral goats in tropical island dry landscapes. In the context of conservation and restoration of tropical island landscapes, the results of our study identify how non-native feral goats use resources across a broad landscape to sustain their populations and facilitate invasion of native plant communities.

    Galectins are β-galactoside binding mammalian proteins characterized by the presence of a conserved carbohydrate recognition domain, expressed in almost all taxa of living organisms and involved in broad range of significant biological and physiological functions. Previously, we reported the purification and extensive characterization of galectin-1 from goat (Capra hircus) heart. Interestingly, the purified protein was found to have significant level of glycosylation. This intrigued us to evaluate the involvement of glycosylation in relation to protein's structural and functional integrity in its purified form. In the present study, an extensive comparative physicochemical characterization has been performed between the glycosylated and deglycosylated form of the purified protein. Deglycosylation resulted in an enhanced fluorescence quenching and marked reduction in pH and thermal stability of the purified galectin. Exposure to various biologically active chemicals showed significant differences in the properties and stability profile, causing significant deviations from its regular secondary structure in the deglycosylated form. These results clearly indicated enhanced structural and functional stabilization in the glycosylated galectin. The data revealed herein adds a vital facet demonstrating the significance of galectin expression and glycosylation in causation, progression, and possible therapeutics of associated clinical disorders. Our approach also allowed us to define some key interactions between the purified galectin and carbohydrate ligands that could well serve as an important landmark for designing new drug protocols for various cardiovascular and neurological disorders.

    Full Text Available The GoSh database (http://www.itb.cnr.it/gosh/ is an online resource including expressedsequence tags (ESTs from Ovis aries and Capra hircus. A total of 58,990 sheep and goat sequences were downloadedfrom GenBank and processed by a semi-automated pipeline, integrating public programs and Perl scripts.Data were collected in a MySQL database, which can be queried via a PHP-based web interface. Sequences wereassembled and a unigene dataset was defined. Three annotation procedures were carried out on all the ESTsequences and all the contig consensus sequences. A procedure was also implemented to infer statistical classificationamong Gene Ontology (GO categories from the ontology occurrences related to the sequences included in thedatabase. A number of programs were used to extract features and give significance to rough sequences. Amongthese, AutoSNP was used to perform putative SNP detection. Further analyses were performed on the GoSh dbdataset, including tandem repeats search and protein patterns identification. The web interface allows users toretrieve significant data and correspondent external links and to download selected sequences and accessory informationin different formats. The resulting web site is a resource of data and links related to goat and sheepexpressed genes.

    Full Text Available In Colombia the rearing of hair sheep and goats are expanding in various regions for being an alternative for meat and milk production at competitive prices due to their adaptability and easiness to digest rough fodder. Among the ectoparasites that affect small ruminants traditionally are recognized the lice and the sheep keds Melophagus ovinus (Díptera: Hippoboscidae, however fleas are not included. Here the occurrence of the common cat flea Ctenocephalides felis felis (Díptera: Siphonaptera affecting sheep and goats in a farm at the Sabana de Bogotá are described an so there was performed an epidemiological and parasitological evaluation. The barn maintained animals in rotational grazing at an approximated stocking rate of 25 head/ha, receiving additional supplements of hay and silage. The presence of the flea was confirmed in sheep and goats, young and adult, as well as in dogs. Diverse degrees of anemia were evidenced but the association between flea infestation and anemia, or the presence of other anemia producing agents could not be studied. In the farm synthetic parasiticides are not used, extracts of Ruda (Ruta graveolens are administered to mitigate parasitosis, without major efficacy. Sheep and goat breeders in the tropics should consider flea infestation as an agent causing adverse animal welfare situations in their farms. Control should start from the knowledge of the life cycle of the flea, trying to interrupt it.

De esta forma se hace una excelente selección genética en función de los litros de leche producidos y de la calidad de la misma. Se ha realizado un ensayo de investigación añadiendo a la dieta de cabras de raza Murciano-Granadina un aditivo con el probiótico: Saccharomyces cerevisiae, y cuyo objetivo es valorar si existe un aumento de la producción total de leche, un aumento en la calidad de la misma y una mejora sanitaria del animal. Se ha utilizado un rebaño formado por 60 cabras, todas al inicio de la lactación, y se analiza: la producción total de leche, proteína, grasa, lactosa, recuento de células somáticas y valores de urea en leche. Los resultados obtenidos concluyen que la adición de lalevadura provoca un aumento del 7% en la producción de leche y unincremento en el porcentaje de grasa en la misma. A su vez se produce un aumento del nivel de urea en leche y una mejora de la condición corporal. También se observa un descenso en los valores del recuento de células somáticas, indicativo de un mejor estado sanitario de los animales.SummaryControl of goat milk production is important because of two reasons: 1 it alows the farmer to feed animals according to their production, 2 it provide Aministration with reliable breed improvement objectives. The Murcia Region has an official dairy control nucleus with 22.000 Murciano-Granadina bred goats. The aim of this nucleus is to obtain objective and reliable data of cuantitative and qualitative production values for each goat of the nucleus. In this way it is possible to carry out a high-qualitygenetic selection process related to the amount and quality of milkproduction. The probiotic aditive (Saccharomyces cerevisiae was administered to the diet of Murciano-Granadina goats in order to evaluate potential increases of milk production, quality, and health improvement of the animals. A 60 goats flock was evaluated at the initial stage of milking for the following parameters: total milk production, proteins, fat, lactose and urea content in milk.A 7% increase in milk production and a higher fat content were observed. An increase of urea content and a better body condition were also seen. Besides a decrease of milk somatic cell content was found, wich indicates a health improvement of animals

    2013-06-30

    The financial analysis and summary results presented in this document represent a first cut at an economic assessment of the proposed Hull Offshore Wind Project. Wind turbine price increases have outpaced the materials and labor price pressures faced by nonrenewable power plant developers due to increased demands on a limited pool of turbine manufacturers and offshore installation companies. Moreover, given the size of the proposed offshore facility, it may be difficult to contract with turbine manufacturers and/or foundation companies given the size and scope of competing worldwide demand. The results described in this report assume that such conditions will not significantly impact the prices that will have to be received from the output of the project; rather, the project size may require as a prerequisite that Hull be able to piggyback on other offshore efforts. The financial estimates provided here necessarily feature a range due to uncertainty in a number of project assumptions as well as overall uncertainty in offshore wind costs. Nevertheless, taken together, the analysis provides a ballpark revenue requirement of approximately $157/MWh for the municipal financing option, with higher estimates possible assuming escalation in costs to levels higher than assumed here.

    Anaerobic fungi occupy the rumen and digestive tract of herbivores, where they play an important role in enzymatic digestion of lignocellulosic and cellulosic substrates, i.e. organic material that their hosts are unable to decompose on their own. In this study we isolated anaerobic fungi from a typical alpine herbivore, the Alpine ibex (C. ibex). Three fungal strains, either as pure culture (ST2) or syntrophic co-culture with methanogens (ST3, ST4) were successfully obtained and morphologically characterised by different microscopy- and staining-techniques and by rDNA ITS gene sequencing. The isolated fungi were identified as Neocallimastix frontalis (ST2) and Caecomyces communis (ST3 and ST4). We introduce a novel field of application for lactofuchsin-staining, combined with confocal laser scanning microscopy. This approach proved as an effective method to visualize fungal structures, especially in the presence of plant biomass, generally exhibiting high autofluorescence. Moreover, we could demonstrate that fungal morphology is subject to changes depending on the carbon source used for cultivation. Oxygen tolerance was confirmed for both, C. communis-cultures for up to three, and for the N. frontalis-isolate for up to 12 h, respectively. With PCR, FISH and an oligonucleotide microarray we found associated methanogens (mainly Methanobacteriales) for C. communis, but not for N. frontalis. PMID:24384307

    Full Text Available The processing, cataloguing, and preliminary analyses of faunal material from the Minoan settlement of Gournia began during the 2012 excavation season. This included backlogged material from the two previous seasons. Excavations during the past three seasons, under Prof. L.V. Watrous and Ph.D. student D.M. Buell from the University at Buffalo SUNY, have revealed a thriving Middle/Late Minoan Period settlement complete with industry, trade, and faunal material. A specific deposit consisting of faunal material, hundreds of stacked conical cups with other assorted shallow bowls and ceramics found within the palace suggest the practice of a specific ritual event that is not unique to Gournia, but compares favorably to similar deposits from across the island. The goal of this project is to examine this ritual practice through the analyzation of the faunal material in context with the other ceramics in order to extrapolate Minoan cultural practices from ritual activity.

    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

    The role played by different mammal species in the maintenance of Trypanosoma cruzi is not constant and varies in time and place. This study aimed to characterise the importance of domestic, wild and peridomestic hosts in the transmission of T. cruzi in Tauá, state of Ceará, Caatinga area, Brazil, with an emphasis on those environments colonised by Triatoma brasiliensis. Direct parasitological examinations were performed on insects and mammals, serologic tests were performed on household and outdoor mammals and multiplex polymerase chain reaction was used on wild mammals. Cytochrome b was used as a food source for wild insects. The serum prevalence in dogs was 38% (20/53), while in pigs it was 6% (2/34). The percentages of the most abundantly infected wild animals were as follows: Thrichomys laurentius 74% (83/112) and Kerodon rupestris 10% (11/112). Of the 749 triatomines collected in the household research, 49.3% (369/749) were positive for T. brasiliensis, while 6.8% were infected with T. cruzi (25/369). In captured animals, T. brasiliensis shares a natural environment with T. laurentius, K. rupestris, Didelphis albiventris, Monodelphis domestica, Galea spixii, Wiedomys pyrrhorhinos, Conepatus semistriatus and Mus musculus. In animals identified via their food source, T. brasiliensis shares a natural environment with G. spixii, K. rupestris, Capra hircus, Gallus gallus, Tropidurus oreadicus and Tupinambis merianae. The high prevalence of T. cruzi in household and peridomiciliar animals reinforces the narrow relationship between the enzootic cycle and humans in environments with T. brasiliensis and characterises it as ubiquitous.

    Being able to recognise when one is being observed by someone else is thought to be adaptive during cooperative or competitive events. In particular for prey species, this ability should be of use in the context of predation. A previous study reported that goats (Capra aegagrus hircus) alter their behaviour according to the body and head orientation of a human experimenter. During a food anticipation task, an experimenter remained in a particular posture for 30 s before delivering a reward, and the goats' active anticipation and standing alert behaviour were analysed. To further evaluate the specific mechanisms at work, we here present two additional test conditions. In particular, we investigated the effects of the eye visibility and head orientation of a human experimenter on the behaviour of the goats (N = 7). We found that the level of the subjects' active anticipatory behaviour was highest in the conditions where the experimenter was directing his head and body towards the goat ('Control' and 'Eyes closed' conditions), but the anticipatory behaviour was significantly decreased when the body ('Head only') or the head and body of the experimenter were directed away from the subject ('Back' condition). For standing alert, we found no significant differences between the three conditions in which the experimenter was directing his head towards the subject ('Control', 'Eyes closed' and 'Head only'). This lack of differences in the expression of standing alert suggests that goats evaluate the direction of a human's head as an important cue in their anticipatory behaviour. However, goats did not respond to the visibility of the experimenter's eyes alone. PMID:26820558

  5. Vasoconstrictive Responses by the Carotid and Auricular Arteries in goats to Ergot Alkaloid Exposure

    2014-11-01

    A fungal endophyte (Neotyphodium coenophialum) infects most plants of ‘Kentucky 31’ tall fescue (Lolium arundinaceum) and produces ergot alkaloids that cause persistent constriction of the vascular system in grazing livestock. Consequently, animals undergoing this toxicosis cannot regulate core body temperature and are vulnerable to heat and cold stresses. An experiment was conducted to determine if the caudal and auricular arteries in goats (Capra aegagrus hircus) vasoconstrict in response to ergot alkaloids. Seven, rumen fistulated goats were fed ad libitum orchardgrass (Dactylis glomeratia) hay and ruminally infused with endophtye-free seed (E-) for a 7-day adjustment period. Two periods followed with E- and endophyte-infected (E+) seed being randomly assigned to the 2 goat groups in period 1 and then switching treatments between groups in period 2. Infused E+ and E- seed were in equal proportions to the hay such that concentrations of ergovaline and ergovalanine were 0.80 µg per g dry matter for the E+ treatment. Cross-sections of both arteries were imaged using Doppler ultrasonography on days 0, 2, 4, 6, 8, and 12 in period 1 and on days 0, 1, 2, 3, 6, 7, and 9 in period 2. Differences from average baseline areas were used to determine presence or absence of alkaloid-induced vasoconstriction. Carotid arteries initiated constriction on imaging day 2 in both periods, and auricular arteries initiated constriction on imaging day 2 in period 1 and on day 6 in period 2. Luminal areas of the carotid arteries in E+ goats were 46% less than baseline areas in both periods after vasoconstriction occurred, whereas auricular arteries in E+ goats were 52% less than baseline areas in period 1 and 38% in period 2. Both arteries in E+ goats in period 1 relaxed relative to baseline areas by imaging day 2 after they were switched to the E- treatment. Results indicated that goats can vasoconstrict when exposed to ergot alkaloids that could disrupt their thermoregulation.

    In a promiscuous species like the domestic goat (Capra hircus), in which maternal investment is greater than paternal investment, a female may mate selectively with a more-fit male to improve her reproductive fitness. Testosterone (T) controls a large suite of male-typical behaviors and morphological characteristics. High T concentrations may be energetically costly or even detrimental to survival; thus, preventing lower quality males from falsely advertising their fitness. Three preference studies were conducted to examine if females use T-dependent cues to assess potential mates. For Experiment 1, females were given a choice between a pair of morphologically similar males, bucks (intact males) and stags (post-pubertally castrated males), during the breeding and non-breeding seasons. In both seasons, females preferred the bucks compared to stags. In Experiment 2, females were given a choice between bucks, stags and wethers (pre-pubertally castrated males) during the non-breeding season. For some comparisons, castrated males received 25 mg testosterone propionate (TP) or were untreated. Females preferred TP-treated males compared to untreated males and showed no preference when given a choice between either two TP-treated or two untreated males. In Experiment 3, females were given a choice between a pair of bucks and a pair of stags treated with 25 mg TP during monthly tests in the breeding season. At each monthly test, females preferred the males with higher T concentrations near the time of the behavior test. These studies suggest that females use T-dependent cues to assess potential mates, and T concentrations may indicate a male's overall fitness. PMID:21056568

  7. Two agricultural production data libraries for risk assessment models

    International Nuclear Information System (INIS)

    Two data libraries based on the 1974 US Census of Agriculture are described. The data packages (AGDATC and AGDATG) are available from the Radiation Shielding Information Center (RSIC), Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831. Agricultural production and land-use information by county (AGDATC) or by 1/2 by 1/2 degree longitude-latitude grid cell (AGDATG) provide geographical resolution of the data. The libraries were designed for use in risk assessment models that simulate the transport of radionuclides from sources of airborne release through food chains to man. However, they are also suitable for use in the assessment of other airborne pollutants that can affect man from a food ingestion pathway such as effluents from synfuels or coal-fired power plants. The principal significance of the data libraries is that they provide default location-specific food-chain transport parameters when site-specific information are unavailable. Plant food categories in the data libraries include leafy vegetables, vegetables and fruits exposed to direct deposition of airborne pollutants, vegetables and fruits protected from direct deposition, and grains. Livestock feeds are also tabulated in four categories: pasture, grain, hay, and silage. Pasture was estimated by a material balance of cattle and sheep inventories, forage feed requirements, and reported harvested forage. Cattle (Bos spp.), sheep (Ovis aries), goat (Capra hircus), hog (Sus scrofa), chicken (Gallus domesticus), and turkey (Meleagris gallopavo) inventories or sales are also tabulated in the data libraries and can be used to provide estimates of meat, eggs, and milk production. Honey production also is given. Population, irrigation, and meteorological information are also listed

    Hawaii's game animals are all non-native species, which provokes human-wildlife conflict among stakeholders. The management of human-wildlife conflict in Hawaii is further complicated by the discrete nature of island communities. Our goal was to understand the desires and perceived values or impacts of game held by residents of Hawaii regarding six game species [pigs ( Sus scrofa), goats ( Capra hircus), mouflon ( Ovis musimon), axis deer ( Axis axis), turkeys ( Melagris gallopavo), and doves ( Geopelia striata)]. We measured the desired abundance of game on the six main Hawaiian Islands using the potential for conflict index and identified explanatory variables for those desires via recursive partitioning. In 2011 we surveyed 5,407 residents (2,360 random residents and 3,047 pre-identified stakeholders). Overall 54.5 and 27.6 % of the emailed and mailed surveys were returned ( n = 1,510). A non-respondent survey revealed that respondents and non-respondents had similar interest in wildlife, and a similar education level. The desired abundance of game differed significantly among stakeholders, species, and islands. The desired abundance scores were higher for axis deer, mouflon, and turkeys compared to pigs, goats or doves. Enjoyment at seeing game and the cultural value of game were widespread explanatory variables for desired abundance. Models for Lanai emphasized the economic value of game, whereas models for Maui identified the potential for game to contaminate soil and water. Models for Oahu and Kauai revealed concern for human health and safety. Given our findings we recommend managers design separate management plans for each island taking into consideration the values of residents.

  9. A Microarray-Based Analysis Reveals that a Short Photoperiod Promotes Hair Growth in the Arbas Cashmere Goat.

    Full Text Available Many animals exhibit different behaviors in different seasons. The photoperiod can have effects on migration, breeding, fur growth, and other processes. The cyclic growth of the fur and feathers of some species of mammals and birds, respectively, is stimulated by the photoperiod as a result of hormone-dependent regulation of the nervous system. To further examine this phenomenon, we evaluated the Arbas Cashmere goat (Capra hircus, a species that is often used in this type of research. The goats were exposed to an experimentally controlled short photoperiod to study the regulation of cyclic cashmere growth. Exposure to a short photoperiod extended the anagen phase of the Cashmere goat hair follicle to increase cashmere production. Assessments of tissue sections indicated that the short photoperiod significantly induced cashmere growth. This conclusion was supported by a comparison of the differences in gene expression between the short photoperiod and natural conditions using gene chip technology. Using the gene chip data, we identified genes that showed altered expression under the short photoperiod compared to natural conditions, and these genes were found to be involved in the biological processes of hair follicle growth, structural composition of the hair follicle, and the morphogenesis of the surrounding skin appendages. Knowledge about differences in the expression of these genes as well as their functions and periodic regulation patterns increases our understanding of Cashmere goat hair follicle growth. This study also provides preliminary data that may be useful for the development of an artificial method to improve cashmere production by controlling the light cycle, which has practical significance for livestock breeding.

    The gonadotropin-releasing hormone (GnRH) plays an important role in the control of reproductive functions. Recent studies have reported the occurrence of GnRH molecular variants in numerous species. In this study, the GnRH1 gene from Jinghai yellow chicken was cloned by reverse transcriptase-polymerase chain reaction and transformed into BL21 (DE3) competent cells. The GnRH1 gene and amino acid sequences were subjected to bioinformatic analyses. The GnRH1 gene nucleotide sequence was discovered to be 352 bp long, containing a coding, promoter, and section of the 3'-regions. The GnRH1 gene shared 93, 81, 54, 58, 61, 76, 76, 59, 76, and 66% sequence identity with Meleagris gallopavo, Columba livia, Homo sapiens, Bos taurus, swines, Capra hircus, Ovis aries, Pantholops hodgsonii, Equus caballus, and Rattus norvegicus, respectively. The GnRH1 gene showed conserved domains. The GnRH1 protein was a secreted protein comprising 92 amino acids, with a molecular weight of 10205.6 Da and a theoretical pI of 5.67. Most of the amino acid residues were observed to be hydrophilic, indicating water solubility. The predicted secondary structures of proteins included α-helices (h; 23.08%), β-extensions (e; 10.92%), and random coils (c; 66.0%). The successful construction of prokaryotic expression vector pET32a-GnRH1 was confirmed by restriction and sequence analysis. SDS-PAGE analysis showed the successful expression of recombinant plasmid in Escherichia coli BL21 (molecular weight = 25-28 kDa). Larger quantities of protein were expressed in supernatant, indicating greater expression in soluble form. Western blot analysis confirmed the expression of the target protein. PMID:25867433

    The stromal vascular fraction (SVF) of adipose tissue in rodents and primates contains mesenchymal stem cells and immune cells. SVF cells have complex metabolic, immune and endocrine functions with biomedical impact. However, in other mammals, the amount of data on SVF stem cells is negligible and whether the SVF hosts immune cells is unknown. In this study, we show that the SVF is rich in immune cells, with a dominance of adipose tissue macrophages (ATMs) in cattle (Bos primigenius taurus), domestic goat (Capra aegagrus hircus), domestic sheep (Ovis aries), domestic cat (Felis catus) and domestic dog (Canis familiaris). ATMs of these species are granulated lysosome-rich cells with lamellipodial protrusions and express the lysosome markers acid phosphatase 5 (ACP-5) and Mac-3/Lamp-2. Using ACP-5 and Mac-3/Lamp-2 as markers, we additionally detected ATMs in other species, such as the domestic horse (Equus ferus caballus), wild boar (Sus scrofa) and red fox (Vulpes vulpes). Feline and canine ATMs also express the murine macrophage marker F4/80 antigen. In the lean condition, the alternative macrophage activation marker CD206 is expressed by feline and canine ATMs and arginase-1 by feline ATMs. Obesity is associated with interleukin-6 and interferon gamma expression and with overt tyrosine nitration in both feline and canine ATMs. This resembles the obesity-induced phenotype switch of murine and human ATMs. Thus, we show, for the first time, that the presence of ATMs is a general trait of mammals. The interaction between the adipose cells and SVF immune cells might be evolutionarily conserved among mammals. PMID:26239911

Os resultados mostraram que predominam as instalações com piso de terra batida (74,8% e descobertas (61,7% e reservatórios de água abertos (83%. Em apenas 3,4% das propriedades a água era tratada. O registro das ocorrências era realizado por apenas 26% dos produtores e 47,6% tratavam o umbigo dos recém-nascidos com iodo. No que diz respeito às carcaças, 31,8% dos proprietários davam destino adequado a elas. A higiene diária das instalações era realizada em apenas 14% das propriedades e a desinfecção em 16,9%. A vermifugação foi a prática mais difundida (88,2% e apenas 6,2% dos produtores dispunham de assistência técnica contínua. Os principais achados clínicos foram sugestivos de doenças infecciosas e parasitárias. Conclui-se que a caprinovinocultura do Sertão de Pernambuco é desenvolvida em instalações modestas, o manejo sanitário é deficiente e as tecnologias disponíveis são pouco utilizadas, impossibilitando a prevenção e controle de doenças, principalmente as de origem infecciosa e parasitária.

    Full Text Available The interaction between ivermectin-resistant and ivermectin-sensitive nematodes and the effect of this anthelmintic on the hematological status of naturally infected goats was assessed using 36 animals. Of these animals, 12 were infected by ivermectin-sensitive gastrointestinal nematodes of the superfamily Trichostrongyloidea (G1s e G1s 12 were infected by ivermectin-resistant nematodes (G2r e G2r and 12 uninfect goats (G3np. Six infected goats of each group (G1sm e G2rm received oral ivermectin al the dose of 200µg/kg, while six were used as controls (G1sc e G2rc. Blood and fecal samples were collected on the day of medication (day zero, at seven, and at 14 days thereafter. The erythrocyte count and hematocrit levels in goats infected by sensitive strains of Haemonchus was greater than that of the group infected by a resistant strain. These values are lower in comparison to those observed in uninfected goats. The increase in the number of eggs per gram of feces, regardless of the strain, is inversely related to the hematocrit level. The use of ivermectin did not significantly change the hematological parameters of goats.

    This research aims at analyzing biogas produced by anaerobic digestion of goat excrements related to energy generation, in addition to analyzing the bio-fertilizer as a byproduct of the process. Therefore, new products are generated from semi-intensive and extensive of goats, increasing its economical and environmental viability of the activity. The biogas was applied as the fuel for an Otto cycle internal combustion engine of 5.5 HP used to drive a hydraulic pump that supplied water to an area of one hectare of pasture. In addition, the spreadsheet GDER was applied to compute the kWh cost of the following electricity sources: biogas from goat excrement, diesel, electrical grid, wind and solar. It was found tat the biogas can substitute 30% of the daily energy requirements, and one can state that 1 m{sup 3} of biogas is equivalent to 740 mL of gasoline. (author)

  9. Usefulness of J-CAPRA score for high-risk prostate cancer patients treated with carbon ion radiotherapy plus androgen deprivation therapy

    International Nuclear Information System (INIS)

    A novel risk assessment method, Japan Cancer of the Prostate Risk Assessment, has been developed based on database of patients receiving primary androgen deprivation therapy. To investigate the usefulness of Japan Cancer of the Prostate Risk Assessment for non-metastatic, high-risk prostate cancer patients treated with carbon ion radio-therapy plus androgen deprivation therapy. Patients with non-metastatic, high-risk prostate cancer (T3, initial prostate specific antigen level ≥20 ng/ml, and/or Gleason score ≥8) were included. The patients were treated with carbon ion radiotherapy (the total dose from 57.6 Gy (relative biological effectiveness)/16 fractions to 66.0 Gy (relative biological effectiveness)/20 fractions), and neoadjuvant as well as adjuvant androgen deprivation therapy for at least 24 months. Four hundred and twenty-six patients were included with the median follow-up of 68.1 months. Of 426, 210 (49.3%), 270 (63.4%) and 251 (58.9%) had Gleason 8-10, prostate specific antigen ≥20 ng/ml and T3, respectively. The 10-year progression-free and cause-specific survival rates in Japan Cancer of the Prostate Risk Assessment 1-2 group (76.5 and 98.9%) were significantly better than those in Japan Cancer of the Prostate Risk Assessment 3-6 group (52.6 and 93.1%), (P < 0.001 and P=0.044, respectively). The median progression-free survivals in the Japan Cancer of the Prostate Risk Assessment 1-2 and 3-6 groups were 158.9 months and 125.9 months (95% confidence interval: 108.6-143.2 months), respectively. For non-metastatic, high-risk prostate cancer patients treated with carbon ion radiotherapy plus androgen deprivation therapy, Japan Cancer of the Prostate Risk Assessment score was useful for predicting the progression-free and cause-specific survivals.

    Since basic information on reproductive behaviour in male Alpine ibex was lacking, I provided in chapter 1, first a detailed description of the mating system and the two alternative mating tactics in this species. I investigated to which extent the adoption of these observed mating tactics in male Alpine ibex can contribute to the exceptional survival described in this species. Some males adopted a tactic termed ‘tending’ to monopolize individual, receptive females by following and defending ...

    The aim of this work was to evaluate the protective effect of catalase (CAT) on frozen/thawed ibex epididymal sperm recovered post mortem, and to detect any harmful effect this might have on sperm fertilisation capacity. Epididymal spermatozoa were diluted using a Tris-citric acid-glucose medium (TCG) composed of 3.8% Tris (w/v), 2.2% citric acid (w/v), 0.6% glucose (w/v), 5% glycerol (v/v), and 6% egg yolk (v/v). Sperm masses from the right epididymis were diluted with TCG medium, while those from the left were diluted with TCG medium supplemented with 200IU/mL CAT. Heterologous in vitro fertilisation (IVF) was used to assess the fertilisation capacity of this sperm. The addition of CAT to the extender did not improve frozen/thawed sperm variables. Moreover, a reduced fertilisation capacity was detected: sperm diluted with TCG provided 25.5% 2PN zygotes, while just 13.2% was recorded for that diluted with TCG-CAT (PTCG sperm than with the TCG-CAT sperm (16.7% vs. 7.6%). The use of 200IU/mL CAT as an additive cannot, therefore, be recommended for the preservation of ibex epididymal sperm. Other antioxidants should, however, be tested in both this and related wild mountain ungulates. PMID:24699464

    The gullet worm (Gongylonema pulchrum) has been recorded from a variety of mammals worldwide. In an earlier study, we demonstrated two separate transmission cycles in cattle (Bos taurus) and wild mammals in Japan based on nucleotide sequences of the ribosomal RNA gene (rDNA) and cytochrome c oxidase subunit I (cox-1) region of mitochondrial DNA of multiple isolates of different origins. Our earlier study additionally demonstrated two major cox-1 haplotypes of G. pulchrum prevalent in cattle in Japan. In the present study, we collected G. pulchrum from cattle and goats (Capra hircus) in Alashan League, Inner Mongolia, China; Gongylonema aegypti from spiny mice (Acomys dimidiatus) in the Sinai Peninsula, Egypt; and Gongylonema neoplasticum from a black rat (Rattus rattus) in Okinawa Island, Japan, to analyze their genetic relationships with G. pulchrum in Japan. The gullet worms from Alashan League had almost identical rDNA nucleotide sequences and two cox-1 haplotypes as seen in G. pulchrum from the cattle in Japan. The two rodent Gongylonema spp. had distinct rDNA nucleotide sequences compared with those of G. pulchrum; only the 18S and 5.8S rDNA sequences showed high identities at 97.2-98.7%, while the remaining sequences were less than 75% identical. The 18S, 5.8S, and 28S rDNA sequences of the two rodent Gongylonema spp. showed nucleotide identities of 99.8% (1811/1814), 100% (158/158), and 98.9% (3550/3590), respectively. The cox-1 regions showed 91.6% (338/369)-92.1% (340/369) identities, with completely identical amino acid sequences. The genetic diversities of three distinct Gongylonema spp. and their possible intraspecific genetic variation may allow us to resolve the taxonomic position of Gongylonema spp. which display few obvious morphological differences from their congeners. Consequently, the Gongylonema isolate from water buffaloes (Bubalus bubalis) in Nepal reported in our previous study is concluded to be a new species, and Gongylonema nepalensis n

    A comparative analysis of erythrocyte membrane proteins of economically important animals, goat (Capra aegagrus hircus), buffalo (Bubalus bubalis), pig (Sus scrofa), cow (Bos tauras), and human (Homo sapiens) was performed. Solubilized erythrocyte membrane proteins were separated by sodium dodecyl sulfate-polyacryamide gel electrophoresis (SDS-PAGE), visualized by staining the gels with Commassie Brilliant Blue (CBB), and identified by matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF/MS). Emerging results show that all major erythrocyte membrane proteins present in human are also seen in all the animals except for band 4.5 which could not be identified. Band 3 is seen as more intense and compact, band 4.1 appears as a doublet in all the animal erythrocyte membranes, band 4.2 exhibits a slightly higher molecular weight (Mr) in buffalo, and cow and band 4.9 has a higher Mr in all the animals relative to the human protein. In addition, there are two new bands in the goat membrane, band G1, identified as HSP 90α, and band G2 identified as HSP 70. A new band C2 identified as HSP 70 is also seen in cow membranes. Peroxiredoxin II is of lower intensity and/or higher Mr in the animals. The difference in size of the proteins possibly indicates the variations in the composition of the amino acids. The difference in intensity of the proteins among these mammalians highlights the presence of less or more number of copies of that protein per cell. This data complement the earlier observations of differences in the sialoglycoprotein profile and effect of proteases and neuraminidase on agglutination among the mammalian erythrocytes. This study provides a platform to understand the molecular architecture of the individual erythrocytes, and in turn the dependent disorders, their phylogenetic relationship and also generates a database of erythrocyte membrane proteins of mammals. The animals selected for this study are of economic importance as

    A 2-yr study investigated effects of different levels of concentrate supplementation on milk production, composition, and lactation curves in pastured dairy goats. For both years, 44 Alpine goats (Capra hircus; 55 +/- 11 kg body weight) were randomly allocated to 4 groups. Animals were supplemented with 0.66 (treatments A and B), 0.33 (treatment C), or 0 kg of concentrate (treatment D) per kg of milk over 1.5 kg/d. Mixed vegetative forages were rotationally grazed by the goats (treatments B, C, and D), except that treatment A was confined and fed alfalfa hay. Individual milk production was recorded daily, and milk samples were collected once every 2 wk for the 7-mo period (March to September) and analyzed for fat, protein, lactose, urea-N, nonesterified fatty acids, and allantoin (second year only). Milk yield and composition varied among dietary treatments, with some measures affected by year. Average daily milk yield was lowest for treatment D. The increased level of concentrate supplementation in treatment A led to 22% greater milk yield compared with treatment D. Milk production increased by 1.7 and 0.9 kg for each additional kilogram of concentrate fed per day during the first and second years, respectively. Average peak yield, time of peak yield, and persistency were lower for treatment D than for other treatments. The percentage of milk fat was lower for treatment D than for other treatments. Concentration of milk protein was greater for treatments A and B during the first year, and was higher for treatment C than for other treatments during the second year. Average milk lactose concentration was higher for treatments B and C than for other treatments. However, milk urea-N concentration in treatment A was higher than other treatments. Milk allantoin, used to estimate microbial proteins synthesis, was 20 to 25% greater for treatment A than for other treatments. Averaged across year, plasma urea-N and nonesterified fatty acids concentration were lowest for

    In animal reproduction technologies, the in vitro embryo culture system has advanced over the past few decades. However, in vitro cultured embryos still have reduced functional and physiological abilities compared with those from in vivo conditions, and many factors of oviduct and uterine environments have not yet been revealed. Here, we demonstrated the in vitro culture of domestic goat (Capra hircus) embryos using two types of culture media, modified synthetic oviductal fluid (mSOF) and a two-step chemically defined medium (DI/II). To obtain parthenogenetic goat embryos, oocytes were matured in vitro in tissue culture media-199 supplemented with 10% fetal bovine serum for 22 to 24 hours, and activated with 5 μM, Ca(2+) ionomycin for 4 minutes, followed by 1.9 mM, 6-dimethylaminopurine treatment for 4 hours. After 2 days of embryo culture in different culture media, there were no significant differences in cleavage rates (96.6% vs. 95.4% in mSOF vs. DI/II, respectively). However, the DI/II group showed improved development competence to blastocysts (64.6% vs. 82.3% in mSOF vs. DI/II, respectively) and the total cell number of blastocysts (144.3 ± 9.2 vs. 264.4 ± 15.2 in mSOF vs. DI/II, respectively) at Day 7. After the cryopreservation of early-stage blastocysts at Day 6 via the conventional slow-freezing procedure, the surviving embryos were analyzed. The re-expansion rate after freezing and thawing was significantly higher in DI/II (39.66% vs. 67.69% in mSOF vs. DI/II, respectively), but there were no statistical differences in total cell numbers (142.3 ± 12.1 vs. 172.1 ± 11.6 in mSOF vs. DI/II, respectively), apoptotic index (4.9 ± 0.8% vs. 3.8 ± 0.7 in mSOF vs. DI/II, respectively), and the gene expression levels (BAX, GLUT1, MnSOD, and OCT4) among the re-expanded blastocysts. Overall, our data reported that the defined in vitro culture media for goat embryos were established with high efficiency, which will be very useful for

Parte de las IgG anti-antígenos ES de T. solium fue conjugado con oro coloidal. La inmunocromatografía se llevó a cabo utilizando tiras de nitrocelulosa en las cuáles se fijó dos bandas con anticuerpos de captura; en la primera, las IgG anti-antígenos ES de T. solium (banda de prueba, y en la segunda las IgG anti-IgG de conejo (banda control. La técnica fue evaluada con un "pool" de tres muestras de medio de cultivo con antígenos ES de T. solium, Hymenolepis nana, Dyphillobotrium pacificum y de larvas de Anisakis simplex, así como con un "pool" de tres muestras fecales de hámsters no parasitados, de parasitados por H. nana y de siete muestras fecales de hámsters parasitados por T. Solium. Resultados: La inmunocromatografía permitió detectar antígenos de T. solium en muestras de medio de cultivo con antígenos ES específicas y en heces de hámsters parasitados por T. solium mediante la coloración de la banda de prueba, siendo negativo cuando se utilizó medios con ES de otros helmintos y sin antígenos, así como con muestras de heces de hámsters infectados por otros parásitos y de no parasitados. En todas las tiras usadas se observó coloración de la banda control. Conclusión: La técnica de inmunocromatografía es capaz de detectar antígenos de T. solium, tanto en medio de cultivo como en heces de hámsters, faltando evaluar la sensibilidad y la especificidad con muestras fecales humanas para el diagnóstico de la teniosis mediante la detección de coproantígenos.

    The Center for Studies and Projects - Naper Solar is an NGO, which works for the dissemination of use of alternative energies resources in the semi-arid Brazilian Northeast in collaboration with the Federal University of Pernambuco. It has implemented caprine raising systems in the back lands of Pajeu in the State of Pernambuco making use of electrified fences energized by solar energy.This project was executed in a joint effort with the City Halls of Afogados da Ingazeira e Sao Jose do Egito and the NGOs Diaconia and the Northeast Woman House and has benefited 20 families of farmers from 9 rural communities. It is funded by a Technical Cooperation Program established between the National Fund for the Environment - Ministry for the Environment and the Netherlands Government. The implemented system, in opposition to the traditional extensive production system, allow for a more animal sanitary control - minimizing the risks of contamination; a more controlled and balanced feeding system - taking into account the weight gaining factor together with pasture management, leading the a guarantee of food supply for the animals. Other advantages of this system include the reduction of fence cost and less deforesting. Electrical fences used in the contention of caprine are built with only 4 straight wires, fixed with isolators on wood posts spaced 10 m from each other, while the conventional fences use 9 barbed-wire lines fixed with clamps on posts spaced 1 m from each other. Therefore, the use of electrical fences instead of the conventional one represent a cost reduction, which can go as high as 40 % of the total cost. Besides that the electrical fences have low maintenance cost, easier and faster installation and relocation. The fenced areas vary from 0.5 ha to 4 ha for the raising of 5 to 50 animals. In the electrification of a fence one needs one photovoltaic module, one electrifier, a battery, isolators (passage and corner), electric ground rods and a thunderbolt deviator kit. In this work the component of an solar electric fence are described together with its main benefits and installation and maintenance costs. (author)

I modelli sono stati formulati mediante Analisi di Funzione Discriminante (Magnusson, 1983; Massolo & Meriggi, 1995 e Analisi di Regressione Logistica (Norusis, 1994. Per lo stambecco i dati sono stati suddivisi in due sets, di cui uno utilizzato per la formulazione del modello e l?altro per la sua validazione. Mediante un test del chi-quadrato sono state confrontate le percentuali di casi classificati nei due sets. Per le altre specie i modelli formulati sono stati applicati al territorio del parco e la validità dei modelli è stata valutata dalla percentuale di casi originali riclassificati correttamente. Per i bovidi il modello a maggior capacità predittiva è stato quello discriminante (classificazioni corrette: 73.0% per stambecco e 82.8% per camoscio. La non significatività del test Χ² (P=0.470 indica che non esistono differenze significative tra la distribuzione reale dello stambecco e quella ottenuta dal modello. L'81.1% del territorio del Parco è idoneo al camoscio alpino e l'area vocata include il 93.6% del territorio realmente occupato dalla specie. Per il capriolo il modello logistico è stato quello a maggior capacità predittiva (88.1% dei casi originali classificati correttamente, individuando il 50.7% del territorio realmente occupato dalla specie. Anche per il cervo quello logistico è preferibile per la maggiore percentuale di casi totali classificati correttamente (AFD: 74.9%; ARL: 76.0%.

    The objective was to characterize the stress response and the seminal parameters obtained with electroejaculation (EE) or transrectal ultrasound-guided massage of the accessory sex glands (TUMASG) in two captive but nondomestic ruminants, the mouflons and the Iberian ibex under general anesthesia. In mouflons, the physiological responses (heart and respiratory rate, rectal temperature, cortisol, creatine kinase, potassium and glucose concentrations) changed similarly with both procedures. The TUMASG procedure was faster than EE in mouflons (21.7 ± 1.4 vs. 12.4 ± 1.2 minutes, P Electroejaculation provided better results in some sperm parameters (mouflons: sperm score: 3.4 ± 0.3 vs. 2.6 ± 0.2 [P < 0.01]; total number of sperm ejaculated: 982.4 ± 299 vs. 710.0 ± 542.2 [P < 0.05]; ibexes: sperm with progressive motility: 47.7 ± 6.2 vs. 20.5 ± 8.3 [P < 0.05]). The transrectal ultrasound-guided massage of the accessory sex glands appears to be an alternative technique to collect sperm from wild ruminants, reducing the need for electrical stimuli and thus decreasing the undesired responses of EE in the more sensitive species. On the other hand, better fresh sperm may be collected with EE. However, TUMASG provides practical advantages in animal welfare, firstly in these wild species more sensible to stress management and capture myopathy. PMID:26174035

    A fragment spanning over exon 2 and intron 2 of major histocompatibility complex B-LB Ⅱ genes was amplified using PCR,cloned and sequenced in 13 individuals from eight Chinese indigenous chicken breeds and one introduced breed. Another 41 sequences of MHC class Ⅱβ from ten vertebrate species were cited from the NCBI GenBank. Thirteen new B-LB Ⅱ alleles were found in the chicken breeds sampled. Alignment of the exon 2 sequences revealed 91.1-97.8% similarity to each other within the chickens sampled, and the chickens shared 84.1-87.0% homology to Phasianus colchicus, 78.5-81.5% similarity to Coturnixjaponica. The sequences in poultry showed 62.6-68.1% identity to HLA-DRBl, 50-61.5% similarity to DQB (HLA-, SLA- and H2-BB), 53.7-60% to HLA-DPB and 53.3-57.8% similarity to HLA-DOB. The frequency of nonsynonymous substitutions of nucleotide was higher than that of synonymous substitutions, and the frequencies of nonsynonymous and synonymous substitutions in poultry B-LB Ⅱ genes were lower than those observed in mammalian DRB1 and DQB1 genes. The deduced amino acid sequences of MHC class Ⅱβ1 domain exhibited extreme difference in conversed region and variable region patterns among the various species, but the two conserved cysteines forming disulfide-bond were shown consistent in poultry with that in mammalian species; and the carbohydrate attachment site was found more conserved in chicken, Homo sapiens, Bos taurus, Ovis aries and Capra hircus than in Sus scrofa and rodent animals. Compared with exon 2 of DQB1 genes of Homo sapiens, ruminant species and Sus scrofa, the differentia that the deletion of six nucleotides at position195 to 200 of exon 2 of DQB1 genes, and insertion of three nucleotides at position 247 to 249 of the exon 2 existed in rodent species were found, which led to the absence of three AA residues at position 65, 66,and 67 within β1 domain of DQB1 chain, and the insertion of one AA residue at position 85.

    According to the highly conservative region of Ets-l gene sequences from bovine (Bos taunts),human (Homo sapiens) and mouse (Mus musculus) in GenBank.the specific primers were designed to clone the cDNA region of Ets-l gene in mammary gland of Xinong Saanen dairy goats using RT-PCR and RACE (rapid amplification cDNA ends) methods,the sequence analyses of nucleotide sequence,and the deduced amino acid sequence of Ets-l gene were conducted. The results showed that the full length of Ets-l gene was 2 263 bp(GenBank accession No.HQ589338), containing 331 bp of 5'UTR,606 bp of 3"UTR,and 1 326 bp of coding sequences (CDS),which encoded a protein of 441 amino acid residues. The nucleotide sequence alignment indicated that the similarities of coding region of goat Ets-l were 98 %,94 %,92 % and 90 %;the similarities of 5 'UTR were 98 %, 85 %, 82 % and 71 %; the similarities of 31JTR were 96 %, 83 %, 81 % and 77 %, compared to those of bovine,porcine,human and rat,respectively. The AA sequence alignment indicated that the protein sequence of goat Ets-l shared high similarities (more than 95 % )with bovine,porcine,human and rat .respectively. The protein molecular weight was 50 340.8 D and the isoelectric point was 5.08. The protein of Ets-l had a helix-turn-helix structure. No transmembrane structure was speculated and no signal peptide was found in the entire sequence. Thus, it can be concluded that the full length cDNA of goat Ets-l gene has been successively cloned.%根据GenBank已收录的牛(Bos taurus)、人(Homo sapiens)和小鼠(Mus musculus)等物种Ets-1基因序列的同源保守区域,设计特异性引物,采用RT-PCR和RACE技术,分离并克隆了西农萨能奶山羊(Capra hircus)Ets-1基因的cDNA序列.该序列全长2263bp(GenBank登录号HQ589338),包括5UTR331 bp,CDS 1 326bp和3'UTR 606 bp,编码441个氨基酸组成的蛋白质.核苷酸序列分析发现,山羊编码序列与牛、猪、人、小鼠等的相应序列同源性分别为98%、94

Um método foi otimizado para preparação do caseinato de sódio em poucos minutos para análise eletroforética. Uréia-PAGE foi o método mais apropriado para identificação desse tipo de fraude, em decorrência da presença da caseína alfas1 com migração mais rápida no leite bovino. A presença da alfas1-caseína bovina foi detectada a partir da adição de 2,5% de leite de vaca utilizando uréia-PAGE. O limite de detecção, a repetibilidade, o tempo para execução indicaram que esse método pode ser aplicado como rotina no controle de qualidade do leite de cabra recebido pelas indústrias de processamento.Polyacrylamide gel electrophoresis (PAGE in presence of urea (urea-PAGE or sodium dodecyl sulfate (SDS-PAGE was evaluated to detect the presence of cow milk added to goat milk. A method was optimized to prepare sodium caseinate from milk in few minutes. After that, the sodium caseinate was analyzed by PAGE. The urea-PAGE was the most appropriated method to identify adulteration as caprine and bovine alphas1-caseins displayed different migration rates. When cow milk was added to goat milk at different proportions, the presence of bovine alphas1-casein was detected in the mixture by urea-PAGE for a minimal proportion of 2.5% of cow milk added to goat milk. The good sensitivity, the repeatability and the short time for execution indicate that the described method will be able to be routinely applied for the quality control of goat milk in dairy industry.

    Full Text Available A Artrite Encefalite Caprina (AEC e a Linfadenite Caseosa (LC possuem alta incidência e transmissibilidade em pequenos ruminantes. Como ambas possuem tropismo por monócitos-macrófagos e afetam mecanismos da resposta inata do hospedeiro, acredita-se que a AEC predispõe o animal a infecções por Corynebacteruim pseudotuberculosis, agente etiológico da LC. Para confirmar esta hipótese, avaliou-se a fagocitose de células da série monócito-macrófago de cabras naturalmente infectadas pelo vírus da AEC (VAEC. Para tanto, foram utilizadas 30 cabras da raça Saanen, alocadas em dois grupos distintos, com 15 animais cada, conforme a sororreatividade de anticorpos séricos antivírus da AEC. Células mononucleares de sangue periférico foram isoladas por gradiente de densidade e plaqueadas para isolamento de células da série monócito-macrófago. Posteriormente, o ensaio de fagocitose de C. pseudotuberculosis foi realizado, após incubação por duas horas a 37ºC a 5% de CO2, e a visualização da fagocitose foi identificada por microscopia óptica. O presente estudo não encontrou diferença na porcentagem de monócito-macrófagos que realizaram fagocitose entre os diferentes grupos (P = 0,41. Todavia, a análise quantitativa de bactérias fagocitadas, demonstrou maior capacidade fagocítica pelos macrófagos-monócitos do grupo sororreagente ao vírus da AEC. Correlação entre monócitos fagocitando e macrófagos que fagocitaram mais de 12 bactérias foi observado neste grupo (r = 0,488; P = 0,006, não sendo o mesmo encontrado no grupo de animais sorroreagentes negativos. Os dados demonstram aumento na intensidade da fagocitose de macrófagos de animais infectados com o vírus da AEC.Caprine arthritis encephalitis (CAE and caseous lymphadenitis (CL have high incidence and transmissibility in small ruminants. Since both virus have tropism for macrophages and monocytes and affect the innate immune response, it is believed that CAE can predispose the animal to infection by Corynebacteruim pseudotuberculosis, the etiological agent of CL. To confirm this hypothesis, we evaluated phagocytosis from the monocyte-macrophage cells from 30 Saanen goats. Goats were uniformly divided in two groups according to results of agar gel immunodiffusion test for CAE virus (CAEV. Peripheral blood mononuclear cells were isolated by density gradient centrifugation and the monocyte-macrophage cells were isolated from the mononuclear cells by their adhesion properties in plaques. Afterwards, phagocytosis of C. psudotuberculosis was performed for two hours at 37ºC, 5% of CO2, and assessed by microscopic visualization. There was no difference in the percentage of monocyte-macrophage cells that phagocytozed C. bovis between groups (P=0.41. However, when phagocytosis rates were classified according to the number of C. pseudotuberculosis phagocyted, the percentage of monocyte-macrophage cells that internalized more than 12 bacteria were higher in serologically CAEV positive animals compared to the serologically negative ones (P<0.001. Furthermore, a positive and significant correlation (r = 0.488; P = 0.006 between the percentage of monocyte-macrophage cells that internalized more than 12 bacteria and the percentage of monocyte that were carrying out phagocytosis was also encountered in serologically CAEV positive goats, however the same were not observed in serologically negative ones. These results demonstrated an alteration in the intensity of C. pseudotuberculosis phagocytosis by monocytes-macrophages from goats infected by CAEV. Thus, these results indicated that goats infected with CAEV may be more susceptible to CL.

    Full Text Available In articles, already published, we have proved that the strain V. B. of Brazilian virus, goes through the placenta (Macacus rhesus (1 and the apparently normal gastro-intestinal tube (1934-1937 (Canis familiaris (2. Today we present the idea that the Brazilian virus can reach the milk of an animal even when the latter has only the unapparent disease. In former articles (**, we have shown that the goat (Capra hircus can be an excellent reservoir of Brazilian virus, having the strain V. B. in its blood and presenting a Weil Felix reaction high and in “group”, with the disease unapparent. When the goats are bred in the laboratory, and even in some foci of the disease, they give a negative Weil Felix, being zero for all the nine strains of Proteus. In the interior of Brazil, in many localities, goats substitute cows, in supplying milk for children and adults, and in some districts goat’s milk is considered superior to cow’s milk, possessing marvellous qualities for men, women an children. Having proved, now, that goat’s milk can contain the virus even when the animal presents nothing clinically, and having also shown that this virus goes through the digestive tube apparently sound, it is easy to understand how infants-in-arms, that is, only a few months old, living in strictly domestic surroundings, can contract the disease; we have many such cases on record. Protocol of the experiments: Goat nº 2, white, January 1948. This animal had been inoculated with the V. B. strain of the Brazilian virus in June 1947, via intra-peritoneal, presenting nothing then, not even a feverish reaction. On that occasion it was not possible to isolate the virus of the blood, although the Weil Felix reaction was positive, high and in “group”.

    PURPOSE To explore whether disparities in outcomes exist between African-American (AA) and Caucasian (CS) men with low-grade prostate cancer (PCa) and similar Cancer of the Prostate Risk Assessment post-Surgery (CAPRA-S) features following prostatectomy (RP) METHODS The overall cohort consisted of 1,265 men (234 AA, and 1,031 CS) who met National comprehensive cancer network (NCCN) criteria for low-intermediate risk PCa and underwent RP between 1990 and 2012. We first evaluated whether clinical factors were associated with adverse pathologic outcomes and freedom from biochemical failure (FFbF) using the entire cohort. Next, we studied a subset of 705 men (112 AA, and 593 CS) who had pathologic Gleason score ≤6 (low-grade disease). Using this cohort, we determined whether race impacted FFbF in men with prostatectomy-proven low-grade disease and similar CAPRA-S score. RESULTS With a median follow up time of 27 months, the overall 7-year FFbF rate was 86% vs. 79% in CS and AA men, respectively (p=0.035). There was no significant difference in ≥1 adverse pathologic features between CS vs. AA men (27% vs. 31%; P =0.35) or CAPRA-S score (p=0.28). In the subset analysis of patients with low-grade disease, AA race was associated with worse FFbF outcomes (p=0.002). Furthermore, AA race was a significant predictor of FFbF in men with low-grade disease (HR 2.01, 95%CI 1.08–3.72; p=0.029). CONCLUSIONS AA race is a predictor of worse FFbF outcomes in men with low-grade disease after RP. These results suggest that a subset of AA men with low-grade disease may benefit from more aggressive treatment. PMID:25304288

    We consider a body moving in a perfect gas, described by the mean-field approximation and interacting elastically with the body, we study the friction exerted by the gas on the body fixed at constant velocities. The time evolution of the body in this setting was studied in Caprino et al. [Math. Phys. 264, 167-189 (2006)], Caprino et al. [Math. Models Methods Appl. Sci. 17, 1369-1403 (2007)], and Cavallaro [Rend. Mat. Appl. 27, 123-145 (2007)] for object with simple shape; the first study where a simple kind of concavity was considered was in Sisti and Ricciuti [SIAM J. Math. Anal. 46, 3759-3611 (2014)], showing new features in the dynamic but not in the friction term. The case of more general shape of the body was left out for further difficulties, and we believe indeed that there are actually non-trivial issues to be faced for these more general cases. To show this and in the spirit of getting a more realistic perspective in the study of friction problems, in this paper, we focused our attention on the friction term itself, studying its behavior on a body with a more general kind of concavity and fixed at constant velocities. We derive the expression of the friction term for constant velocities, we show how it is time dependent, and we give its exact estimate in time. Finally, we use this result to show the absence of a constant velocity in the actual dynamic of such a body.

    Full Text Available Changes in the microbial flora of “Caprino dei Nebrodi”, a raw goat’s milk cheese produced in Sicily, were studied during ripening. From 2 batches of cheese, 4 samples were taken at day 0, 2, 15, and 30 of ripening. Also, samples of curd and milk used in the manufacturing process were analyzed. By the end of the ripening process (day 30, high log10 cfu/g were found for Lactobacilli (7.20, Lattococci (7.10, and Enterococci (7.00, whereas counts of Enterobacteriaceae (3.91, Escherichia coli (3.30, and Staphylococcus (3.89 were found to be lower. The study provides useful information on the microbiological properties of “Caprino dei Nebrodi” cheese, and the results obtained suggest that in order to increase the quality of this artisanal product, it is necessary to improve the sanitary conditions of milking and cheese-making. The study was intended as a preliminary step towards the isolation and identification of bacterial species found in this type of goat’s cheese.

  8. Incidence of Old World screw-worm fly, Chrysomya bezziana in Iraq

    International Nuclear Information System (INIS)

    The Old World screw-worm fly (OWSWF), Chrysomya bezziana Villenuve, is a member of the insect family Calliphoridae and is an obligate parasite of warm-blooded animals in the tropics and sub-tropics (Norris and Murray 1964). Flies lay their eggs on the edge of wounds or body orifices; the resulting larvae invade the host tissues and produce lesions and infertility if the genitals become infested (Humphrey et al. 1980). Recorded hosts include cattle (Bos indicus), sheep (Ovis aries), goats (Caprus hircus), dogs (Canis familiaris), cats (Felis domesticus) and man (Homo sapiens) (Patton 1920, 1922, Stoddar and Peck 1962, Norris and Murray 1964). This investigation describes the incidence of myiasis caused by C. bezziana in Iraq from September 1996 to March 1998

    Full Text Available Descreve-se a ocorrência de carcinoma de células escamosas (CCE bem diferenciado em caprinos de duas propriedades no Estado do Pará. Foram observadas a prevalência, a correlação com a pigmentação da região perineal e as características macro e microscópica das lesões. As lesões consistiram em tumores no períneo, com grau de desenvolvimento, diâmetro e forma variados. Em uma propriedade no município de Viseu, dos 347 caprinos, 20 apresentaram CCE (5,8%. A neoplasia só foi observada em animais com a região perineal despigmentada. Em outra propriedade, no município de Garrafão do Norte, descreve-se a ocorrência de três casos em um rebanho de 400 caprinos (0,75%. A elevada ocorrência deste tumor deve-se, provavelmente, à despigmentação do períneo e à cauda curta e elevada das cabras, que expõe a região perineal à alta incidência de radiação ultravioleta naquela região.Squamous cell carcinoma in goats of two farms in the State of Pará is described. Prevalence, correlation with the pigmentation of the perineal area and macro and microscopic characteristics of the lesions were studied. The tumors on the perineum were of varied development degrees, diameters and forms. On one farm, in the county of Viseu, from a total of 347 goats, 20 presented the neoplasia (5.8%. On the second farm, in the county of Garrafão do Norte, three cases of squamous cell carcinoma in a herd of 400 goats (0.75% were observed. The tumor was only observed in animals in which the perineal area was despigmented. The high incidence of this tumor appears to be due to lack of pigmentation at the períneo and the high and short tail of the goats, that exposes the area to intense ultraviolet radiation in the tropics.

    Full Text Available Grupos de caprinos mestiços castrados e inteiros foram abatidos com idades de 175, 220, 265 e 310 dias. Os efeitos da castração e idade de abate nas qualidades físico-químicas, sensoriais e aromáticos da carne caprina foi pesquisado. O efeito castração foi observado apenas para o conteúdo de cálcio, no entanto a idade de abate apresentou um efeito significativo nos teores de umidade, proteína, cálcio, ferro e pH. Os fatores idade de abate e castração não apresentaram efeito significativo nos percentuais de fosfolipídeos porém, a idade de abate afetou os percentuais de colesterol. Caprinos castrados apresentaram maior percentual de ácidos graxos insaturados e, conseqüentemente, maior relação PUFA/SFA. Os ácidos graxos foram afetados significativamente pela castração. Não foram observadas variações nos percentuais dos ácidos graxos saturados e insaturados da carne caprina de animais abatidos com diferentes idades. O fator idade de abate apresentou maior efeito nos atributos sensoriais analisados do que o fator castração. Nos extratos da carne caprina foram identificados um total de cento e oito voláteis, sendo estes: 41 hidrocarbonetos alifáticos, 12 hidrocarbonetos alicíclicos, 19 aldeídos, 9 compostos benzênicos, 9 álcoois, 7 cetonas, 4 compostos sulfurados, 2 terpenoídes, 2 ésteres e 3 outros compostos. Os extratos da carne de caprinos castrados continham maior número de compostos voláteis do que os extratos de animais inteiros. O fator idade de abate foi o parâmetro que mais afetou as características físico-químicas e sensoriais da carne caprina. O fator castração afetou diretamente a produção de voláteis.

    Full Text Available Formagelle di capra is a raw goat cheese produced from whole chilled goat milk; traditional technology involving unpasteurised milk and indigenous lactic starter cultures is employed for its production in Italy. The purpose of this study was to assess the behaviour of Escherichia coli O157:H7 during the manufacturing and ripening of this raw goat milk cheese. Raw milk was experimentally inoculated with E. coli O157:H7 in a laboratory scale plant and the count was monitored during production and 30 days of ripening required for this cheese. Results showed that E. coli O157:H7 count increased to more than 1.5 Log cfu g–1 during cheese production and remained constant until the end of ripening. The evidence that E. coli O157:H7 is able to survive during the manufacturing and ripening process suggests that the 30-day ripening period alone is insufficient to eliminate levels of viable E. coli O157:H7 in Formaggelle di capra cheese and that the presence of low numbers of E. coli O157:H7 in milk destined for the production of raw goat milk cheeses could represent a potential source of infection for humans and a threat for consumers.

    To identify potential migraine therapeutics, extracts of eighteen plants were screened to detect plant constituents affecting ADP induced platelet aggregation and [14C]5-hydroxytryptamine (5-HT) release. Extracts of the seven plants exhibiting significant inhibition of platelet function were reanalysed in the presence of polyvinyl pyrrolidone (PVP) to remove polyphenolic tannins that precipitate proteins. Two of these extracts no longer exhibited inhibition of platelet activity after removal of tannins. However, extracts of Crataegus monogyna, Ipomoea pes-caprae, Eremophila freelingii, Eremophila longifolia, and Asteromyrtus symphyocarpa still potently inhibited ADP induced human platelet [14C]5-HT release in vitro, with levels ranging from 62 to 95% inhibition. I. pes-caprae, and C. monogyna also caused significant inhibition of ADP induced platelet aggregation. All of these plants have been previously used as traditional headache treatments, except for C. monogyna which is used primarily for protective effects on the cardiovascular system. Further studies elucidating the compounds that are responsible for these anti-platelet effects are needed to determine their exact mechanism of action. PMID:10664475

Os dados foram obtidos da Gaasa e Alimentos LTDA, uma empresa que participa do Programa de Melhoramento Genético de Caprinos e Ovinos (GENECOC da Embrapa Caprinos. Inicialmente, 3.573 registros foram analisados por meio do procedimento MIXED do pacote estatístico SAS (1999. As análises foram realizadas considerando os efeitos da diferença genética aditiva entre as raças, de dominância e de recombinação. O peso ao nascer foi influenciado pelos efeitos genéticos aditivos, enquanto o peso ao desmame e o ganho de peso pré-desmame foram influenciados por efeitos genéticos não-aditivos. A estimativa de herdabilidade direta para o peso ao nascer foi moderada, o que indica a existência de variabilidade genética passível de ser explorada por meio da seleção individual. Do mesmo modo, as estimativas de herdabilidade das características idade ao primeiro parto e peso total das crias ao nascer indicaram a existência de variabilidade genética para obter ganhos genéticos por meio da seleção. Os genes das raças Poll Dorset e Dorper tiveram papel importante para melhor desempenho ponderal, portanto, essas raças podem ser indicadas como paternas no cruzamento terminal.

    Full Text Available A mastite é a inflamação da glândula mamária que acomete raças de aptidão leiteira como também aquelas voltadas para produção de carne. Esta enfermidade ocasiona sérias alterações na produção de leite e na sua qualidade, redução no ganho de peso e mortalidade de cordeiros. O presente estudo teve por objetivo conhecer os principais agentes causadores de mastite em ovinos e caprinos, bem como a sua susceptibilidade aos agentes antimicrobianos, além de avaliar o grau de concordância entre testes diagnósticos. Foram visitadas 25 propriedades durante a realização do experimento, sendo criatórios de caprinos, ovinos e rebanhos mistos, nos estados de Pernambuco e Bahia. Coletou-se leite de 439 caprinos e 76 ovinos. Foi realizada lactocultura, o California Mastitis Test (CMT e o teste de sensibilidade aos antimicrobianos. Além disso, determinou-se o grau de concordância entre os testes diagnósticos empregados. Foi constatada uma maior freqüência de Staphylococcus spp. nos casos de mastite em caprinos e ovinos, sendo observado ainda, isolados de Streptococcus spp., Corynebacterium spp. e bacilos gram negativos (BGN. Os isolados apresentaram alta sensibilidade aos antimicrobianos testados, sendo o menor percentual de sensibilidade observado para o ácido nalidíxico. Em relação ao diagnóstico da mastite caprina, a análise comparativa entre o exame microbiológico e o CMT demonstrou um grau de concordância igual a K=0,17, enquanto que para a espécie ovina, este valor foi de K=0,22. A utilização do CMT para o diagnóstico da mastite subclínica em cabras e ovelhas deverá ser associado à técnica da lactocultura.Mastitis is an inflammation of mammary gland, that are important in milking breed as well in meat ones.

Objetivou-se conhecer o atual manejo sanitário empregado e os problemas sanitários existentes na opinião do criador do Ceará. O trabalho foi realizado nas várias regiões criadoras de caprinos de raças leiteiras, nativas ou sem raça definida. Foram selecionadas 127 propriedades onde se aplicou um questionário. A percentagem média de mortalidade de animais foi de 22,8% e 4,6% em jovens e adultos, respectivamente. Os sinais clínicos relatados, por ordem, foram: anemia e edema de barbela (81,9% dos criatórios, diarréia (78,7%, aborto (75,6%, pododermatite (67,7%, linfadenite (66,9%, ectoparasitoses (63,8%, mamite (51,2%, pneumonia (44,9%, lesões vesiculares de pele (35,4%, ceratoconjuntivite (29,1%, problemas de ordem nervosa (26,8%, malformação fetal (15%, criptorquidismo (11%, prolapso de vagina/útero (11% e artrite (8,7%. Pode-se concluir que o manejo sanitário dos caprinos desses criatórios é precário, independente do tipo de exploração ou regime de criação, a mortalidade de animais, principalmente de jovens, é considerada alta. Mesmo em criatórios com exploração leiteira não existe uma preocupação rigorosa com higiene e qualidade do leite.

    Full Text Available Toxoplasmosis is one of the more prevalent parasitic infections in human beings and animals, and its transmission has been usually attributed to the ingestion of undercooked or raw meat from infected livestock, the rate of infection of those animals has great importance for the study of this protozoosis. In farm animals such as swines, sheeps and goats, the infection for the T. gondii is common and can bring reproductive problems. Infected animals possess amount of cysts of the parasite in organs and muscles and these are not detected during the inspection of the meat in the slaughterhouse. This revision emphasizes aspects of toxoplasmosis in swines, sheeps and goats, cattles, horses and chickens aiming to clarify the potential of each species as source of transmission of the parasite, mainly in Brazil.A toxoplasmose é uma das infecções parasitárias mais prevalentes no homem e nos animais, e a sua transmissão tem sido usualmente atribuída à ingestão de carnes cruas ou mal cozidas, de animais de produção infectados, sendo a taxa de infecção destes animais de grande importância para o estudo desta protozoose. Em animais de produção tais como suínos, bovinos, ovinos e caprinos a infecção pelo T. gondii é comum e pode levar a problemas reprodutivos. Animais infectados possuem grande quantidade de cistos do parasita em variados órgãos e músculos e estes não são detectados durante a inspeção da carne nos abatedouros. Esta revisão enfatiza aspectos da protozoose em suínos, caprinos e ovinos, bovinos, eqüinos e aves visando esclarecer o potencial de cada espécie como fonte de infecção do parasita, principalmente no Brasil.

No presente estudo os ovinos e bovinos também foram sensíveis à intoxicação pelas folhas de M. princeps. A menor dose que causou a morte dos ovinos foi 10g/kg e dos bovinos foi 20g/kg. A sintomatologia nas duas espécies foi pouco específica; a evolução da intoxicação experimental nos ovinos variou de 6h4min a 99h e nos bovinos foi de 4h46min a 75h30min. Nos achados de necropsia destacaram-se derrames cavitários e edemas, especialmente no tecido perirrenal (presente em 4 de 6 dos ovinos e em 2 de 3 bovinos. Muito características foram as alterações renais, sob forma de necrose coagulativa dos túbulos uriníferos no córtex renal (encontrada em 8 dos 9 bovinos, exceto em um, no qual a evolução da intoxicação foi muito breve, e em todos os 6 ovinos. Em 5 dos 6 ovinos foi constatada, adicionalmente, lesão hepática sob forma de uma tumefação difusa de todos os hepatócitos, alteração que não foi verificada nos bovinos.

O delineamento experimental empregado foi blocos casualizados, em esquema fatorial 4 x 5, compreendendo quatro fontes de matéria orgânica (esterco de galinha, esterco bovino, esterco caprino e húmus de minhoca e cinco doses, sendo 0; 5; 10; 15 e 20 t/ha de esterco de galinha; e, 0; 10; 20; 30 e 40 t/ha de esterco bovino, caprino e húmus de minhoca, em quatro repetições. Utilizaram-se parcelas com 20 plantas, espaçadas de 1,00 x 0,50 m. Os resultados indicaram que o comprimento de vagens aumentou linearmente com as doses de estercos de galinha, de bovino e de caprino. O peso médio de vagens foi influenciado apenas pelo esterco de galinha. O húmus de minhoca não exerceu efeito sobre a característica e a produtividade de vagens. O esterco de galinha na dose de 13,0 t/ha proporcionou rendimento máximo de vagens (26,3 t/ha, o esterco bovino na dose de 24,0 t/ha produziu 30,3 t/ha e o esterco caprino, na dose de 16,6 t/ha, produziu 23,0 t/ha. A análise econômica indicou a dose de 11 t/ha de esterco de galinha e de 23,0 t/ha de esterco bovino, como as mais viáveis economicamente para adubação orgânica no feijão-vagem, resultando num rendimento estimado de 11,3 e 21,2 t/ha de vagens e uma receita prevista de 8.000 e 21.000 kg/ha de vagens, respectivamente. Para o esterco caprino, 20 t/ha apresentou saldo um pouco superior à sua ausência, enquanto 10 t/ha de húmus de minhoca revelou saldo de R$ 2.336,00/ha, porém, inferior à sua ausência.

    More than two decades ago, Fritjof Capra commended - and indeed advocated – a paradigm shift in health science and care. In his book The Turning Point (1982 he talks of a major shift from the preoccupation with micro-organisms to a careful study of the ‘host organism and its environment’, of ‘significant attempts to develop a unified approach to the mind/body system’ in Western medicine, of  ‘a new holistic paradigm’ (as opposed to ‘the old biomedical paradigm’ regarding the problem of health and healing, of ‘a holistic and humanistic approach to primary care’, and of ‘a holistic therapy’ as opposed to ‘the traditional biochemical practice of associating a physical disease with a specific physical cause’. Our concern in this article is with the paradigm shift advocated by Capra in this book and the progress that has since been made.

    Opsomming

    Meer as twee dekades gelede het Fritjof Capra ‘n pleidooi gelewer vir ‘n paradigmaskuif vanaf die bio- mediese model na ‘n meer holistiese, ekosistemiese model van gesondheid en genesing. Die vraag wat in hierdie artikel aan die orde kom is of praktisyns in die veld van die gesondheidswetenskappe sedertdien daarin geslaag het om die oorgang na die aanbevole paradigma te maak. ‘n Oorsig van die literatuur sedert 1982 toon dat die skuif nog nie regtig gemaak is nie. ‘n Ander literatuuroorsig toon voorts dat die terme ‘gesondheid’, ‘well-being’ en ‘wellness’ as uitruilbaar beskou word en dat hulle betekenisse meermale afhang van die gebruikskonteks. Op grond van hulle bespreking van die antropologiese ekosistemiese benadering tot gesondheid en genesing stel die outeurs voor dat die terme ‘gesondheid’ en ‘wellness’ as korrelatiewe gebruik word, en dat die term ‘well-being’ gebruik word vir al die domeine van menslike lewe en bestaan wat kan bydra tot gesondheid, oftewel ‘wellness’.

    Full Text Available Arquivos de fichas clínicas de ruminantes ou amostras para diagnósticos recebidos pelo Hospital Veterinário da Universidade de Campina Grande, em Patos, Paraíba, de janeiro 2000 a agosto 2007, foram revisados para avaliar alguns aspectos epidemiológicos de doenças parasitárias de ruminantes na região semi-árida da Paraíba e estados vizinhos. A região apresenta precipitações médias anuais de aproximadamente 800mm, com chuvas irregulares concentradas em um período de 3-4 meses e uma temperatura média anual de 26°C. No período, 163 (5,31% de 3.064 ruminantes foram afetados por alguma doença parasitária clinica. A doença parasitária mais frequente em caprinos e ovinos foi a helmitose gastrointestinal, principalmente a hemonchose, e caprinos foram mais afetados (6,24% dos casos diagnosticados do que os ovinos (4,7% dos casos diagnosticados. A maior freqüência da doença nos caprinos pode estar associada à maior susceptibilidade destes ou devido a erros no tratamento, como a utilização da mesma dose para as duas espécies, o que para a maioria dos anti-antihelmínticos é insuficiente para caprinos. Bovinos tiveram uma baixa freqüência de helmintoses gastrintestinais (1 de 1.113 casos. Esta baixa freqüência deveu-se, provavelmente, ao sistema de criação no semi-árido, com baixa taxa de lotação, até um animal adulto por hectare a cada 13-16 hectare, e a permanência de bezerros (suscetíveis com as mães (resistentes por períodos de até um ano antes da desmama. A ocorrência de eimeriose em caprinos e ovinos foi de 0,76% dos casos, envolvendo apenas os animais jovens. Em bovinos a principal doença foi à tristeza parasitária com 14 surtos. Os surtos de tristeza ocorreram principalmente no final do período chuvoso em áreas de desequilíbrio enzoótico incluindo as montanhas e planaltos da região da Borborema, áreas irrigadas, e áreas das bacias do Rio do Peixe e Rio Piranhas.

    Full Text Available Para determinar a ocorrência de diferentes intoxicações por plantas na região do Seridó Ocidental e Oriental do Rio Grande do Norte foram entrevistadas 82 pessoas, entre produtores e técnicos em 17 municípios. De acordo com esse inquérito as duas intoxicações mais importantes são as por Ipomoea asarifolia, que causa sinais nervosos em ovinos, caprinos e bovinos, e por Aspidosperma pyrifolium que, segundo os entrevistados, causaria abortos em caprinos, ovinos e bovinos. O efeito abortivo desta última planta foi comprovado em caprinos, mas não em bovinos e ovinos. Alguns entrevistados mencionaram, também, a intoxicação por A. pyrifolium como causa de sinais nervosos em bovinos e eqüídeos, o que ainda não foi comprovado. Intoxicações por plantas cianogênicas, incluindo Manihot spp, Anadenanthera colubrina var. cebil (=Piptadenia macrocarpa, Sorghum bicolor e Sorghum halepense são importantes na região. São importantes, também, as intoxicações por Prosopis juliflora em bovinos e, com menor freqüência, em caprinos, por Crotalaria retusa em eqüinos, ovinos e bovinos e por Mascagnia rigida em bovinos. As intoxicações por Brachiaria decumbens e Enterolobium contortisiliquum ocorrem esporadicamente. Outras intoxicações menos importantes são as causadas por Indigofera suffruticosa, Ipomoea carnea e Ricinus communis. Diversos produtores descreveram a intoxicação por Marsdenia sp afetando ovinos e bovinos, além de um surto em suínos que foram alimentados com as raízes da planta. Foi demonstrado que tanto as raízes da planta quanto as folhas são tóxicas para ruminantes, causando sinais nervosos, mas sem lesões histológicas. Outra intoxicação relatada pelos produtores e comprovada experimentalmente foi a causada por Tephrosia cinerea em ovinos, que causa um quadro clínico de ascite, com lesões de fibrose hepática.

    Full Text Available An efficient burning of the plutonium produced during light water reactor (LWR operation has the potential to significantly improve the sustainability indices of LWR operations. The work offers a comparison of the efficiency of Pu burning in different reactor configurations—a molten salt fast reactor, a LWR with mixed oxide (MOX fuel, and a sodium cooled fast reactor. The calculations are performed using the HELIOS 2 code. All results are evaluated against the plutonium burning efficiency determined in the Consommation Accrue de Plutonium dans les Réacteurs à Neutrons RApides (CAPRA project. The results are discussed with special view on the increased sustainability of LWR use in the case of successful avoidance of an accumulation of Pu which otherwise would have to be forwarded to a final disposal. A strategic discussion is given about the unavoidable plutonium production, the possibility to burn the plutonium to avoid a burden for the future generations which would have to be controlled.

    Science.gov (United States)

    Sissom, Matthew

    The field of physics has always fascinated me, but I never possessed the mathematical skills necessary to extend that interest past the point of curiosity. This thesis was set up to explore how I and other writers, specifically Walt Whitman, use(d) the skills we do have to ask and attempt to answer the same cosmic questions normally reserved for scientists overseeing particle collider experiments. In Tao of Physics, Fritjof Capra attempted to blend the principles of Eastern philosophy with the movements associated with modern physics. In doing so, he offers up a few insights into the human desire to "divide the world into separate objects and events" (117), which I believe, when it comes to fiction, greatly influences the audience's interpretive framework. Capra suggests, "To believe that our abstract concepts of separate `things' and `vents' are realities of nature is an illusion" (117). Humans use this division to cope with our everyday environment, yet it is not a fundamental feature of reality but, rather, an abstraction devised by our discriminating and categorizing intellect. It is a coping mechanism, as Capra refers to it, that pins writers in a corner, encouraging them to forms and styles set by their predecessors to better satisfy the "discriminating and categorizing intellect" of their audience. Writers often struggle to achieve a balance between accurately presenting the human condition that, like Capra's description of subatomic particles as "intrinsically restless" (117), changes based on myriad variables and properly structuring their writing to fit a predetermined model. Whitman, a fan of popular science, drew from the scientific world, using his understanding of the interpretive framework, to better craft his poems' metaphors. In "Song of Myself," Whitman suggests that the celebration of one's own existence cannot be separated from the celebration of the universe, "For every atom belonging to me as good belongs to you" (1-3). Whitman's writing

  2. Development of plutonium: Fast Neutrons Reactors option

    International Nuclear Information System (INIS)

    Phenix reactor is shortly described with combustible assembly with some operational data. 'CAPRA'(Plutonium Enhance Consumption in Fast Reactors) is an R and D program for the development of an optimized combustible for fast reactors for burning more plutonium. Three ways are tested: a 45% Pu concentration in an oxide fuel keeping actual fabrication and reprocessing options giving a 80 kg/TWh Pu consumption, a fuel without U238 but with a W or a Mo matrix with problems of reprocessing and core reactivity giving a 110 kg/TWh Pu consumption, and a nitride fuel with an up to 65% Pu concentration giving a 90 to 100 kg/TWh Pu consumption.

    In the 27th issue of the Weekly Bulletin (28th June 2004) we have reported, under the heading "Lord Shiva Statue Unveiled", that "Carl Sagan drew the metaphor between the cosmic dance of the Nataraj and the modern study of the ‘cosmic dance' of subatomic particles." In fact, as was kindly pointed out to us by his editors, it was Fritjof Capra,  who in his well-known book "The Tao of Physics" (1975), drew this metaphor, and not Carl Sagan. We have apologized for this unintentional misappropriation and we have also modified the relevant part of the text as shown on the explanatory plaque adjacent to the statue.

    The acute phase proteins (APP) are a group of serum proteins that change their concentration in animals following external or internal challenges, such as infection, inflammation or stress. The concentrations of four APPs, including serum amyloid A (SAA), haptoglobin (Hp), alpha(1)-acid glycoprotein (AGP) and ceruloplasmin (Cp) were determined in serum collected from healthy Alpine ibexes (Capra ibex) and ibexes with Sarcoptes scabiei mange. Primary structures of all four APPs were determined by cDNA sequencing. The concentrations of all four APPs were higher in serum of animals with clinical signs of sarcoptic mange when compared to healthy animals. Two of the APPs, including SAA and AGP, acted as major APPs, since their serum concentrations were increased more than 10-folds when compared to healthy animals (Psarcoptic mange in free ranging animals.

    Full Text Available PHYGROW, a hydrologic-based forage simulation model, was parameterized to represent a typical South Texas ranch engaged in the production of cattle and meat goats with an indigenous population of white-tailed deer. Forage production and associated stocking rates for two cattle:goat ratios were simulated with POPMIX for 20 years. Two ten-year weather scenarios, one representing normal conditions (30% drought years and one representing dryer weather conditions (50% drought years were analyzed. Management decision rules (ASPC were developed for the region to produce estimates of annual animal production and operating costs for the enterprises on each of the four scenarios. These performance and cost data were then used as input into FLIPSIM, a firm level income and policy simulator, along with relevant product and input price data for the region. Integration of modeled results produced useful information showing the socioeconomic consequences for a typical South Texas firm impacted by alternative climatic conditions and management strategies.Um modelo de simulação de produção de forragem (PHYGROW, foi parametrizado para representar uma fazenda típica no Sul do Texas envolvida com a produção de bovinos, caprinos e de animais silvestres (cervo.

A escassez de publicações contendo informações específicas sobre o leite de cabra motivou a realização deste artigo. Para a realização da revisão bibliográfica foi feita uma busca de artigos científicos nas bases de dados da SpringLink, Nature, Scientific Electronic Library Online, principalmente, acessados através do portal de periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior por intermédio do Sistema Integrado de Gestão Acadêmica da UFJF. As principais palavras-chave utilizadas como descritor do assunto foram "leite de cabra" em português, em inglês "goat milk" e em espanhol "leche de cabra". O leite de cabra tem um importante papel como fonte de cálcio, de gordura de elevada digestibilidade, de proteína de alto valor biológico e hipoalergenicidade. Comparando o leite caprino com o leite bovino em relação aos aspectos composicionais, observou-se que os leites das duas espécies são distintos. Informações específicas sobre o leite de cabra facilitam o seu processamento e desenvolvimento de novos produtos a partir deste. As propriedades nutricionais e funcionais do leite de cabra justificam sua singularidade e demonstram que o leite caprino e seus produtos representam um nicho promissor para diversificar e inovar a indústria láctea. As propriedades sensoriais relativas ao sabor e odor do leite de cabra representam dificuldades para a sua aceitação, sendo necessárias pesquisas para melhorar estas características.

    A Peste des Petits Ruminants virus (PPRV) was isolated from an outbreak that occurred in sheep and goats in Nanakpur village of Mathura District in Uttar Pradesh (India). Based on hemagglutination of chicken red blood cells (rbcs), cytopathic effect similar to that caused by the Morbilliviruses in Vero cells, and amplification and sequence analysis of the viral nucleoprotein (N) gene, the identity of the virus was confirmed as PPRV and named PPRV/C. hircus-tc/India/2012/Nanakpur1 (in short PPRV/Nkp1/2012). However, based on its poor neutralization with monoclonal antibodies, escape detection by commercial ELISA, and unsuccessful amplification of the hemagglutinin (H) and the fusion (F) genes by several pairs of published PCR primers it was concluded that the PPRV/Nkp1/2012 may not be closely related to lineage type IV PPR viruses believed to be present in the Indian subcontinent. A plaque assay for titration of the PPRV was developed for the first time. The virus was plaque purified and its growth characteristics were studied in the African green monkey kidney (Vero) cells and baby hamster kidney (BHK-21) cells. In a one-step growth curve analysis it was concluded that the duration of the PPRV life cycle is 6-8h, an uncharacterized part of PPRV replication. These findings provide information for devising control strategies against PPR in India by choosing a homologous candidate vaccine prototype. PMID:23500799

    Full Text Available RESUMEN: El análisis de los restos faunísticos del castro astur de La Campa Torres ha permitido aproximarnos a las estrategias paleoeconómicas de uno de los asentamientos asturianos fortificados más importantes de la Edad del Hierro. El vacuno supone el principal recurso ganadero de la ocupación prerromana complementada, marginalmente, con el ganado lanar, caprino y porcino. La escasa frecuencia de los restos de caballo y perro constatan un patrón habitual en la mayoría de los yacimientos protohistóricos, aunque el despiece exhaustivo de algunos canes no descarta el consumo de estos carnívoros. La actividad cinegética resulta ser testimonial como complemento a la dieta, representada tan sólo por el ciervo.ABSTRACT: The study of the faunal remains of Campa Torres has allowed to approximate us to the paleoeconomical patterns of one of the most important fortified Iron Age hillforts in Asturias. The cattle supposes the main stock during the prerroman occupation, complemented marginally with the sheep, goat and pig. The low frequency of the horse and dog bones states a habitual pattern as in most of the prehistoric sites, although the exhaustive disarticulation marks of dogs do not discard the consume of these carnivores. The hunting activities are evidenced only by some testimonial remains of red dear.

    The efficacy of in-feed fenbendazole at a dose rate of 7.5 mg/kg bodyweight for three consecutive days was assessed in five Arabian oryx (Oryx leucoryx), six scimitar-horned oryx (Oryx dammah), 14 slender-horned gazelles (Gazella leptoceros), eight Soay sheep (Ovis aries aries soay), 13 alpine ibex (Capra ibex ibex), six red deer (Cervus elaphus hippelaphus) and 11 Nelson's elk (Cervus elaphus nelsoni) kept in five herds in a zoo. The efficacy was assessed by means of repeated faecal egg count reduction (fecr) tests and in vitro egg hatch assays. Fenbendazole was highly effective against nematodes in five of the seven species, consistently reducing egg shedding by more than 90 per cent. In the egg hatch assays of the five herds, 50 per cent inhibition of hatching (ld50) was observed at a concentration of thiabendazole below 0.1 microg/ml. In the Arabian oryx and alpine ibex the efficacy of fenbendazole was less than 90 per cent, and the ld50 in the egg hatch assays was between 0.1 and 0.2 microg/ml thiabendazole. PMID:16272545

    A total of 250 patients with diagnosed bronchial asthma (BA) were examined by microbiological methods. Among them--188 children and 62 adults. In 87 patients the microflora of nasal mucosa was studied, in 40--of pharynx only and in 123 patients--both the nasal and the pharynx. For comparative analysis earlier data obtained in 69 patients with persistent allergic rhinitis (PAR) were used. The cultures isolated from the nasal mucosa of BA patients were shown to number 18 genera and 42 species, while among those isolated from pharynx mucosa 20 genera and 40 species. Monocultures were isolated from the nasal mucosa only in 23% of the examined patients and from the pharynx mucosa--only in 1.42%. Associations with different numbers of components were isolated from nasal and pharynx mucosa (2 to 6, 2 to 8 respectively). Staphylococcus aureus was regarded as the main species of nasal biocenosis in BA and PAR, as well as pharynx biocenosis in BA. Besides, in BA other Staphylococcus species (schleiferi, caprae, capitis, hominis, etc.), reversely related to the main species, could be isolated from both mucous membranes. Similarities and differences in microflora of biocenoses in both nosological forms, confirming links between PAR and BA, are considered. PMID:15881942

    Full Text Available Background: Despite their frequency as contaminants, coagulase-negative Staphylococci (CONS have become important nosocomial pathogens, accounting for 9% of all nosocomial infections. These infections are difficult to treat because of the risk factors and the multiple drug resistance nature of these organisms. Materials and Methods: One hundred and two consecutive CONS were isolated from various clinical samples like blood, pus, urine, urine catheter tip and gastric lavage. Most of the blood samples were from patients with risk factors (immunocompromised or on medical devices. After confirming the isolates as CONS, species-level identification was performed by simple, non-expensive conventional methods and antibiotic sensitivity testing was also carried out. Results: Of 102 CONS isolates, 100 isolates could be identified to the species level. Among the 100 isolates, epidermidis was the most common species isolated, seen in 32%, followed by S. hemolyticus (18%, S. lugdunensis (12%, S. hominis (10%, S. saprophyticus (8%, S. capitis (6%, S. caprae (4%, S. xylosus (4%, S. cohni and S. warneri (3% each. In the present study, 56% of the isolates were methicillin-resistant CONS. Most of the isolates showed resistance to ampicillin and amoxyclav (89% each, followed by ceftriaxone (52%, cotrimoxazole (46%, cefotaxime (32%, gentamicin (25%, amikacin (21%. Conclusion: The increased pathogenic potential and multiple-drug resistance demonstrates the need to adopt simple, reliable and non-expensive methods for identifying and determining the antibiotic sensitivity of CONS.

    Numerous species of Sarcocystis have been reported from wild ruminants, but none has been named from the Rocky Mountain goat (Oreamnos americanus). Mature sarcocysts were found in frozen muscle samples of three of seven mountain goats from Alaska, USA. Two morphological types of sarcocysts were found; one had Sarcocystis cornagliai-like sarcocysts, previously named from the Alpine ibex (Capra ibex) from Europe. Two other goats were infected with a new species, Sarcocystis oreamni. Sarcocystis oreamni sarcocysts were microscopic with 2 μm-thick sarcocyst wall. By transmission electron microscopy, the sarcocyst wall had 1.7 μm-thick with unusual molar tooth-like villar protrusions (vp), type 29. The vp had an electron dense core and two disc-shaped plaques at the tip with fine microtubules. Bradyzoites were 8.6-9.1 μm long. Single nucleotide polymorphism (SNP) identified in 18S rRNA, and 28S rRNA loci of rDNA regions that suggested S. oreamni molecularly apart from related species. The phylogenetic analysis based on 18S rRNA and 28S rRNA sequences suggested S. oreamni is related with Sarcocystis species that employ members of the Canidae family as their definitive host.
