    Full Text Available The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia’s transition to a market economy and during the accession period to the European Union (EU. The non-parametric method Data Envelopment Analysis (DEA was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000–2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU’s investment support schemes in new member states.;

    Full Text Available Economic weights for milk carrier (water plus lactose, fat and protein yields, calving interval, age at first service, interval between the first service and conception of heifers and length of productive life of Estonian Holsteins were estimated under assumed milk production quota and for non-quota conditions. A bio-economic model of an integrated production system of a closed herd was used. Economic values of milk carrier yield and length of productive life differed between quota and non-quota conditions, but there were only minor differences between those marketing systems in economic values for functional traits. The standardised economic values of the most important traits varied in magnitude between18 to 81% of the economic value for milk yield. Discounting had a substantial impact on the economic value of length of productive life. When defining the breeding objective for Estonian Holstein, the interval between the first service and conception of heifers, and the length of productive life should be included in the breeding goal along with the traits with the highest economic value, milk, fat and protein yield. In the optimum breeding objective, relative weights of production vs. functional traits were 79 and 21%, respectively.;

    Financing constraints on beef cattle farm nowadays have received attention by the government through distributed various assistance programs and program loans through implementing banks. The existing financing schemes are all still conventional yet sharia-based. The purpose of this research is to formulate financing pattern for sharia beef cattle farm. A qualitative and descriptive approach is used to formulate the pattern by considering the profit-sharing practices of the beef cattle farmers. The results of this study have formulated a financing pattern that integrates government, implementing banks, beef cattle farmers group and cooperative as well as breeders as its members. This pattern of financing is very accommodating of local culture that develops in rural communities. It is expected to be an input, especially in formulating a business financing policy Sharia-based beef cattle breeding.

    This study aims to present the current data in the existing situation and potential of the cattle breeding. East Anatolia has an important place in Turkey's cattle breeding sector. Thus, Aǧrı is one of the key cities in the region and livestock breeding is a major resource of income for the population. According to Turkish Statistical Institute's data, the city of Aǧrı has the 8th place with its 321 710 head of cattle currently. In cattle gene types, with 170 583 head in local breeds it is in the first place, while it is in the 10thplace with a total of 131 195 head in crossbreeding and it stands in 63th place with 19 932 head culture race. Once again, according to the Turkish Statistical Institute's data, cattle farming brought in 382 987 750 TL as a result of 259 011 tons of the milk, 5 665 tons of meat and 8 887 skins. In 2014, Turkish Ministry of Food, Agriculture and Livestock subsidized cattle farming in the city by paying 20 551 816 TL. Therefore, it is important to determine the existing conditions of livestock sector of the city, especially cattle farming, with regard to its potential and problems. Consequently, it would be possible to develop short term, mid-term, long term goals and solutions for the problems. As a conclusion, the city has a remarkable place in the region with its cattle population, characteristics of animal production and its position in the employment. Aǧrı represents a small model in local level for Turkey's overall livestock farming.

    Full Text Available The development of cattle farming has influenced and modeled the social and economic organization of Uruguay along history and has culturally acquired several expressions, including decisive evidence in the historical organization of its territory and the conformation of its rural landscape. The historic marks of cattle farming are key to understand the logics of land use planning and the natural-culturalconstruction of the Uruguayan landscape and have exerted great influence on the country’s internal policy organization, the division of land, the organization of roads and trails, its toponymy, etc. From the modifications of flora and fauna caused by the first introduction of cattle in the country, the conformation of the rural landscape of our territory has been linked to cattle farming, especially to the economic unit represented by the “estancia ganadera” (cattle farm. Its historic evolution delineated processes for land occupancy, holding and exploitation which lasted very long periods and with the so called “modernization of cattle farming” established the way and typology of rural architecture as well as forestry treatment and equipment which defined the predominant profile of rural areas in the country. The estate systems related to the industrialization of meat, which resulted from the productive situation of the country in the 70’s are also as significant, although their territorial dimension is much less. These industrial remains (unequally preserved, recognized and restored require to be approached as cultural landscapes and demand the set up of their links with the territory and the productive chain. This approach focuses on recognizing and activating the most significant elements of this cultural heritage, integrating its management to cattle farming today and to sustainable strategies of local and regional productive development.

  9. Significance of Neospora caninum in cattle farming

    2006-01-01

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

  10. Conservation versus traditional cattle farming - the economic implications

    Directory of Open Access Journals (Sweden)

    J.W. Hearne

    2003-12-01

    Full Text Available In many areas of South Africa traditional subsistence farming practices entail overstocking of cattle. The resulting damage to the veld can be arrested only by providing the farmers with economic incentives to reduce stocking densities. In this paper cattle offtake strategies are investigated with a view to maximising revenue at lower stocking densities. This is achieved by developing a mathematical model which predicts the revenue generated by a given strategy. It is shown that although the model is nonlinear, a transformation can be made to enable optimisation by linear programming.

    Full Text Available The aim of this experiment was to identify improvement demands for farms with different levels of competitiveness in the west of Rio Grande do Sul state, Brazil. A total of 63 owners of large farms were interviewed (farms with an area greater than 900ha by applying a semi-structured questionnaire, guided by four drivers: technology (TEC, management (MAN, market relations (MR and the institutional environment (IE.It was used the Statistical Analysis System 9.2 software to perform the cluster analysis and identify farmers' characteristics. Three random clusters with different levels of competitiveness were observed: low competitiveness level (LCL, middle competitiveness level (MCL and high competitiveness level (HCL. The 29 variables (sub factors were evaluated in the cluster analysis according to level of impact on competitiveness, being classified into variables of high, medium or low impact. Stratification was carried out, ranking demands for improvements from aspects attributed by experts in relation to sub factors. The farmers with low competitiveness level (LTL had an unfavorable status for MAN, while the farmers belonging to clusters MCL and HCL have, respectively, favorable and neutral status for the same driver. The management characteristics determined the level of competitiveness of the farms surveyed

  12. Potential for transmission of infections in networks of cattle farms

    2010-09-01

    Full Text Available The aim of this analysis is to evaluate how generic properties of networks of livestock farms connected by movements of cattle impact on the potential for spread of infectious diseases. We focus on endemic diseases with long infectious periods in affected cattle, such as bovine tuberculosis. Livestock farm networks provide a rare example of large but fully specified directed contact networks, allowing investigations into how properties of such networks impact the potential for spread of infections within them. Here we quantify the latter in terms of the basic reproduction number, R0, and partition the contributions to R0 from first order moments (mean contact rates and second order moments (variances and covariances of contact rates of the farm contact matrices. We find that the second order properties make a substantial contribution to the magnitude of R0, similarly to that reported for other populations. Importantly, however, we find that the magnitude of these effects depends on exactly how the contacts between farms are defined or weighted. We note that the second order properties of a directed contact network may vary through time even with little change in the mean contact rates or in overall connectedness of the network.

    2005-01-01

    Full Text Available In the paper we presented five-year investigations of numeric and structural changes in cattle karyotype on five farms and two centers for reproduction in Serbia. There were 371 breeding animals (215 male and 156 female, out of which 267 Holstein Friesian breed (193 male and 74 female, 62 Simmental (17 male and 45 female and 42 Grey Steppe breed (5 male and 37 female. Cultivating of lymphocytes and karyotype analyses, according to the international standards for karyotypization of domestic animals, were applied. The aim of the investigation was to test genetic material on chromosome level of animals introduced into reproduction. The following changes were discovered in the karyotype: 6 animals of Holstein-Friesian breed were with chimeras 2n=60XX/XY and there was one Robertson's translocation in Simmental breed. Structural changes as breakage and a ring were discovered in two animals of Holstein-Friesian and Simmental breed raised in the area of bombing in Serbia. The animals of Grey Steppe breed had normal karyotype. There is a total of 9 animals with changes (2.42%, while 362 were with normal karyotype, total 97.57%. According to the results, it may be concluded that cytogenetical attestation of the breeding animals will have to be continued for the purpose of protecting the genofond on cattle farms.

    Fate and occurrence of fourteen androgens, four estrogens, five glucocorticoids and five progestagens were investigated in three swine farms and three dairy cattle farms with different farming scales and wastes disposal systems in China. Twenty-one, 22, and 12 of total 28 steroids were detected in feces samples with concentrations ranging from below method limit of quantitation (< LOQ for estrone) to 8100 ± 444 ng/g (progesterone), in wastewater samples with concentrations ranging from < LOQ (estrone) to 20,700 ± 1490 ng/L (androsterone), in suspended particles with concentrations ranging from < LOQ (17β-trenbolone) to 778 ± 82.1 ng/g (5α-dihydrotestosterone) in the six farms, respectively. The steroids via swine farms and human sources were mainly originated from wastewater into the receiving environments while those steroids via cattle farms were mainly from cattle feces. The total contributions of steroids to the environment in China are estimated to be 139, 65.8 and 60.7 t/year from swine, dairy cattle and human sources, respectively. - Highlights: ► 28 steroids were investigated in three swine farms and three cattle farms. ► Eight detected synthetic steroids were from exogenous usage. ► Lagoon systems were more effective in removing steroids than sedimentation tanks. ► The steroids via swine and human sources were mainly from wastewater. ► The steroids via cattle were mainly originated from feces. - The swine and cattle farms contribute higher steroids masses to the environment than the human sources.

    The objective of this study was to determine whether dairy farms with poor cow welfare could be identified using a national database for bovine identification and registration that monitors cattle deaths and movements. The welfare of dairy cattle was assessed using the Welfare Quality(®) protocol (WQ) on 24 Portuguese dairy farms and on 1930 animals. Five farms were classified as having poor welfare and the other 19 were classified as having good welfare. Fourteen million records from the national cattle database were analysed to identify potential welfare indicators for dairy farms. Fifteen potential national welfare indicators were calculated based on that database, and the link between the results on the WQ evaluation and the national cattle database was made using the identification code of each farm. Within the potential national welfare indicators, only two were significantly different between farms with good welfare and poor welfare, 'proportion of on-farm deaths' (ptree based on two variables, 'proportion of on-farm deaths' and 'calving-to-calving interval', and it was able to correctly identify 70% and 79% of the farms classified as having poor and good welfare, respectively. The national cattle database analysis could be useful in helping official veterinary services in detecting farms that have poor welfare and also in determining which welfare indicators are poor on each particular farm.

    White, Andrew J.; Kirk, Donald W.; Graydon, John W.

    2011-01-01

    The production of biogas through the anaerobic digestion of cattle manure and its subsequent use in the generation of electricity on larger farms in Ontario is currently economically attractive. This is a result of the Ontario Feed-In Tariff (FIT) program, which provides incentivized rates for the production of electricity from biogas. Although larger farms can take advantage of the higher rates for electricity, there are substantially more smaller farms for which individually designed and engineered biogas systems would be prohibitively expensive. By employing the concept of modular biogas plants, this analysis evaluates the economics of small-scale biogas utilization systems. Dairy farms with at least 33 animals and beef farms with at least 78 animals can operate economically attractive biogas systems. This analysis shows that approximately 9000 additional Ontario cattle farms would be able to take advantage of the FIT program, which would add 120 MW e of renewable energy capacity to the Ontario electrical grid.

    Tick-borne diseases (TBDs) impose a significant constraint to livestock production world widely. In this paper, we presented a case of TBD in a cattle farm in Henan, China. 35 blood samples (7 samples sent by veterinarian, 28 samples gathered by our colleagues) were collected from ill, surviving and asymptomatic cattle and microscopic observation and PCR assays were conducted to characterize the pathogens. Genus Ixodes feeding on these cattle were collected and identified. Theileria annulata-like and Anaplasma marginale-like pathogens were observed in the blood smears stained with Giemsa staining under microscope. Furthermore, 5 out of 7 cattle blood samples were found to be positive for T. annulata by PCR. In the 28 blood specimens, three were positive for T. annulata, while A. marginale DNA was detected in nine blood DNA samples. Besides, 56 ticks feeding on cattle were collected from this farm and were all identified as Rhipisephalus microplus, meanwhile, 10 of them were found to be positive for A. marginale. In addition, phylogenetic analysis of the msp4 gene sequences of A. marginale obtained in this study showed that the isolate from cattle (KX840009) fell in the same clade with that of R. microplus (KX904527), sharing 100% similarity. To the best of our knowledge, this is the first confirmed report of outbreak of theileriosis/anaplasmosis in cattle farms in Henan, China. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available Indonesian archipelago consists of five main islands and more than seventeen thousand of small islands. These small islands are very effective as natural barrier to the spread of contagious animal diseases. This situation is very advantageous to develop many programs such as beef cattle farming to support beef self sufficient program in 2010. However, there are some constraints in developing of these small islands, namely human resources, natural resources, infrastructure, mean of communications and transportations and lack of intra sector integrated coordination. In taking the advantageous of developing small islands as a screening base and quarantine area, animal production technologies and veterinary science are much needed. The development can be done in integration with transmigration development program so that the beef cattle development could become source of income and job opportunity for the transmigran and local inhabitant as well. Beef cattle farming scheme are recommended by doing cow-calf operation or fattening. Political support from government and legislative are needed in establishment of infrastructure in the area chosen as beef cattle farming location. Besides, it need facilitations in land procurement for beef cattle farming, legal aspect, supports of law enforcement, simple regulation in land used and zone management planning, regulation in controlling beef importation, and credit with minimum interest rate.

  7. Reducing the environmental impact of methane emissions from dairy farms by anaerobic digestion of cattle waste.

    2011-08-01

    Four dairy cattle farms considered representative of Northern Spain milk production were studied. Cattle waste was characterised and energy consumption in the farms was inventoried. Methane emissions due to slurry/manure management and fuel consumption on the farms were calculated. The possibility of applying anaerobic digestion to the slurry to minimise emissions and of using the biogas produced to replace fossil fuels on the farm was considered. Methane emissions due to slurry management (storage and use as fertiliser) ranged from 34 to 66kg CH(4)cow(-1)year(-1) for dairy cows and from 13 to 25kg CH(4)cow(-1)year(-1) for suckler calves. Cattle on these farms are housed for most of the year, and the contribution from emissions from manure dropped in pastures is insignificant due to the very low methane conversion factors. If anaerobic digestion were implemented on the farms, the potential GHG emissions savings per livestock unit would range from 978 to 1776kg CO(2)eq year(-1), with the main savings due to avoided methane emissions during slurry management. The methane produced would be sufficient to supply digester heating needs (35-55% of the total methane produced) and on-farm fuel energy requirements. Copyright © 2011 Elsevier Ltd.

    Full Text Available Electric production from renewable resources, such as solar photovoltaic (PV, is playing an increasingly essential role in the agricultural industry because of the progressive increase in the energy price from fossil fuels and the simultaneous decrease in the income deriving from farming activities. A central issue in the sustainable diffusion of PV technologies is represented by the actual energy efficiency of a PV system. For these reasons, a performance analysis has been carried out in order to assess the potentials offered by different PV plants within a defined geographical context with the aim of investigating the impact of each component has on the PV generator global efficiency and defining the main technical parameters that allow to maximise the annual specific electric energy yield of an architectonically integrated plant, installed in a dairy house, compared to a ground-mounted plant. The annual performances of three grid connected PV plants installed in the same dairy cattle farm have been analysed: two are architectonically integrated plants - i.e., a rooftop unidirectional and a multi-field systems (both 99 kWp - and the other is a ground-mounted plant (480 kWp. Furthermore, the electrical performances, estimated by the photovoltaic geographical information system (PVGIS, developed by the EU Joint Research Centre, and by an analytical estimation procedure (AEP, developed on the basis of a meteo-climatic database related to the records of the nearest weather station and integrated by the components’ technical specifications, have been compared with the actual yields. The best annual performance has been given by the ground-mounted PV system, with an actual increase of 26% and in the range of 6÷12% according to different estimations, compared to the integrated systems, which were globally less efficient (average total loss of 26÷27% compared to 24% of the ground-mounted system.

    Full Text Available This study was conducted to determine the concentration and frequency distribution of certain airborne micro-organisms on cattle farms and their potential health hazards to farm workers. The samples (60 air samples and 240 hand and nasal swabs from cattle farm workers were collected from ten cattle farms (five dairy barns and five beef sheds located in the Sharkia Governorate of Egypt. Air samples were collected for microbiological examination in liquid media using an all-glass impinger whereas those for fungal examination were placed on agar plates using slit air samplers (aeroscopes. The results showed that the overall means of total culturable bacterial and fungal counts were lower in the air of dairy cattle barns than in beef cattle sheds. Identification of the isolated bacteria revealed the recovery of the following species (from dairy cattle barns versus beef cattle sheds: Staphylococcus epidermidis (26.7% vs 36.7%, S. saprophyticus (20% vs 33.3%, S. aureus (10% vs 16.7%, Enterococcus faecalis (23.3% vs 26.7%, Enterobacter agglomerans (23.3 vs 13.3%, Escherichia coli, (16.7% vs 26.7%, Klebsiella oxytoca, (10% vs 16.7%, K. pneumoniae (3.3% vs 0%, Proteus rettegri (6.7% vs 13.3%, P. mirabilis (10% vs 10%, P. vulgaris (3.3% vs 6.7%, Pseudomonas species (6.7% vs 16.7%, respectively.

    A study monitoring cystic echinococcosis (CE) in adult dairy cattle from intensive livestock farms located in the municipality of Arborea (Sardinia, Italy) was carried out between 2012 and 2015. A retrospective study of veterinary reporting forms of post-mortem inspections in 10 different Italian slaughterhouses was also performed. In addition, data on viability and molecular characterisation of hydatid cysts removed from parasitised organs in cattle was carried out. A geographical information system (GIS) with data layers of the study area and the geo-referenced points of 160 cattle farms was constructed. CE was found in 21.9% (35/160) of the surveyed farms. The retrospective study revealed that 0.05% (13/23,656) of adult slaughtered animals (over one year of age) from Arborea had tested positive to CE. The results stratified per year showed the following CE prevalences: 0.09% (5/5673) in 2012; 0.02% (1/5682) in 2013; 0.08% (5/6261) in 2014; and 0.03% (2/6040) in 2015 (χ2 with 3 degrees of freedom=3.81; P=0.282). The E. granulosus sensu stricto (formerly called G1 or sheep strain) was detected in all cysts subjected to molecular analysis. The GIS analysis showed that CE is fairly resilient in the Arborea territory where most of cattle farms are located, while a small cluster of cases was found located in the southeastern part of Arborea, close to districts where sheep farms are situated. The present survey reports the presence of CE in Sardinian dairy cattle intensive farms and suggests that the parasitic pressure of CE in the island continues to be very strong.

  14. Linking bovine tuberculosis on cattle farms to white-tailed deer and environmental variables using Bayesian hierarchical analysis.

    W David Walter

    Full Text Available Bovine tuberculosis is a bacterial disease caused by Mycobacterium bovis in livestock and wildlife with hosts that include Eurasian badgers (Meles meles, brushtail possum (Trichosurus vulpecula, and white-tailed deer (Odocoileus virginianus. Risk-assessment efforts in Michigan have been initiated on farms to minimize interactions of cattle with wildlife hosts but research on M. bovis on cattle farms has not investigated the spatial context of disease epidemiology. To incorporate spatially explicit data, initial likelihood of infection probabilities for cattle farms tested for M. bovis, prevalence of M. bovis in white-tailed deer, deer density, and environmental variables for each farm were modeled in a Bayesian hierarchical framework. We used geo-referenced locations of 762 cattle farms that have been tested for M. bovis, white-tailed deer prevalence, and several environmental variables that may lead to long-term survival and viability of M. bovis on farms and surrounding habitats (i.e., soil type, habitat type. Bayesian hierarchical analyses identified deer prevalence and proportion of sandy soil within our sampling grid as the most supported model. Analysis of cattle farms tested for M. bovis identified that for every 1% increase in sandy soil resulted in an increase in odds of infection by 4%. Our analysis revealed that the influence of prevalence of M. bovis in white-tailed deer was still a concern even after considerable efforts to prevent cattle interactions with white-tailed deer through on-farm mitigation and reduction in the deer population. Cattle farms test positive for M. bovis annually in our study area suggesting that the potential for an environmental source either on farms or in the surrounding landscape may contributing to new or re-infections with M. bovis. Our research provides an initial assessment of potential environmental factors that could be incorporated into additional modeling efforts as more knowledge of deer herd

    Concentrations of cadmium, lead, iron, zinc, copper, chromium, nickel, aluminium and arsenium were analysed in blood serum of cattle from organic (n=20) and conventional (n=21) farms. The elements were determined by inductively coupled plasma atomic emission spectrometry using an Optima 2000 DV instrument (Perkin Elmer Inc.). Animals from the organic farm were characterised by significantly lower (Panimals from the conventional farm. The concentration of Cd was similar in animals from both organic and conventional farms. The concentration of toxic elements in cattle from organic and conventional farms studied was very low. The trace essential elements were generally within the adequate ranges except Zn and Cu, which were deficient. In organically reared animals, also serum Fe content was below the critical level for diagnosing iron deficiency. Pb was significantly correlated with Cd, Zn, Fe, Cu and Ni. A significant positive correlation between the concentration of Cd and Zn, Cu and Ni concentrations was only observed in cows from the organic farm. The present results suggest that organically raised animals are less exposed to harmful environmental influences such as the environmental pollution with heavy metals. On the other hand, these animals are at a greater risk of mineral deficiency compared to animals kept on conventional farms.

    Full Text Available A survey of the management of mixed farming of cattle and antelope and use of anthelmintics was conducted on eleven farms between August and December 1999 by a self-administered questionnaire. Seventeen antelope species ranging from grey duikers (Sylvicapra grimmia to eland (Taurotragus oryx occurred on the farms. Impala (Aepyceros melampus was the most abundant antelope on the farms. Seventy-five per cent of the antelope species on the farms were grazers and mixed feeders and shared grazing with cattle. Most farmers (n =8 did not consider the stocking density for cattle and antelope as an important management factor. Fifty-four per cent of the farmers (n = 6 routinely dewormed both cattle and antelopes. Albendazole and fenbendazole were the most commonly used drugs for deworming cattle (72.7 % and antelope species (54.5 %. The deworming of antelope was carried out during the dry season, using albendazole-, fenbendazole-and rafoxanide-medicated supplementary feed blocks. Doramectin injections were given to antelopes on two farms. Cattle were dewormed preventively and according to the general body condition of the animal. Few farmers (n = 4 followed the recommended deworming programme for cattle in Zimbabwe and only one farmer followed a specified dosing programme for game. However, results from the survey on the deworming of game indicate that farmers perceived helminth infections in antelope to be important.

    This paper reported on a study that was conducted in 2003 to 2005 at beef and diary cattle farms in Canada, where cattle manure was anaerobically digested for biogas production. The biogas was used for electrical and thermal energy cogeneration. Manure from about 7500 beef cattle at a feedlot was digested at a thermophilic temperature of 55 degrees C in two 1800 m{sup 3} above-ground digesters with a hydraulic retention time (HRT) of 14 days. The biogas had an average 58 per cent methane content and was combusted in a General Electric Jenbacher 999 kW cogeneration system. At the second farm, manure from about 165 lactating cows, 110 heifers and 40 calves was digested at a mesophilic temperature of 40 degrees C in a 500 m{sup 3} below-ground digester with a HRT of 28 days. The unique feature of this digester was that it was retrofitted in a pre-existing larger slurry storage tank. The biogas had an average 65 per cent methane content and was combusted in a 75 kW Perkins dual fuel diesel engine connected to a 65 kW Schnell generator. In 2007, when fats, oils and grease (FOG) from restaurant waste residue was added to the manure, biogas production increased by about 300 per cent and electrical energy generation increased by 180 per cent. Both systems have operated year-round from December to February at average ambient temperatures that ranged from -9 to -12 degrees Celsius. This paper addressed the long-term sustainability options for animal farm operations in terms of biogas production for electricity and thermal energy cogeneration.

    Full Text Available An integrated farming system is one of the alternatives for climatic change mitigation. This paper reports the application of corn-cattle based integrated farming system in Agrotechno Park Center of Palembang, and discusses its impact on CO2 fixation and the reduction of methane emissions. The study was based on the data of the first 6 yr from 2003 until 2009. The CO2 fixed in the soil and plants was determined based on the content of organic C which was multiplied by the index of 3.67. The methane gas produced by Balinese cattle and its dung was observed and modified into feed rations. The results showed that soil organic C increased from 40.80 tons C/ha in the 1st yr to 66.40 tons C/ha in the 6th yr. In addition, there was organic C fixation equivalent to 93.95 tons of CO2e. Corn biomass increased from 6.67 tons/ha to 18.66 tons/ha, equivalent to an increase in the fixation of atmospheric CO2e as much as 19.80 tons CO2e/ha. The supplementation of 60%-80% grass fodder with concentrate lowered the concentration of methane gas in cattle breathing by 28.7%, from 617 ppm to 440 ppm, while the methane emissions from cattle manure decreased by 31%, from 1367 mL/head/d to 943 mL/head/d. Installing a bio digester that generates biogas served to accommodate methane gas emissions from cattle dung and used it for bioenergy. Composting reduced the formation of methane gas from cattle manure through a regular process of turning over that gives aeration and forms aerobic condition in the heap of cattle dung. Recycling produces a variety of organic products that store carbon for a longer period of time and slowed the conversion of organic C into CO2. This study showed that the diverse activities of an integrated crop-cattle farming could be an alternative solution to climatic change mitigation.

    2010-01-01

    Full Text Available This study aimed to develop an assessment scheme for the evaluation at farm level of beef cattle welfare in the intensive rearing system that is capable of both identifying weak points in animal welfare and grading farms to such extent. The basic principle of the method was the avoidance of animal handling and the prolonged observation of cattle using animal-based and resource provision measures grouped in four classes of parameters: 1 Housing systems and facilities; 2 Health and cleanliness; 3 Animal behaviour and reactivity; 4 Quality of management and stockmanship. Each parameter was graded giving the highest scores to the best option for animal welfare, and the threshold value for distinguishing good from poor welfare conditions was set primarily on the results of scientific reports and investigations. An overall Welfare Index was calculated summing the scores of the 4 classes of parameters to formulate a general judgement of the farm and to allow comparison among them. The protocol was applied to 102 Italian intensive beef cattle farms rearing more than 300 young bulls/year. Regarding housing and facilities, the study showed that space allowance and space at the manger were the most frequent critical points. Within the “poor welfare” farms, more than 80% provided less than 3.5 m2/head to bulls weighing more than 500 kg, and none adopted a feeding frontage of at least 60 cm/head. Negatively judged farms compared to those ranked in the good welfare area for health and cleanliness showed a higher incidence of emergency slaughter (score 1.7: >1% vs score 3: 0.5-1%, P<0.05 and lameness (score 1.9: 1.5-3% vs score 3.3: <1.5%, P<0.05. Animal behaviour and reactivity parameters showed that in the “poor welfare” farms, bulls had a quicker flight reaction to the presence of both farmer and observer (P<0.01 likely due to a negative human-animal interaction. The quality of stockmanship was the category in which the highest number of farms

The objectives of our study were to review the present state of knowledge on M. bovis excretion, transmission, and survival in the environment and the interactions of wildlife and cattle with the intention of determining if the current recommendations by MDARD on farm practices are adequate and to identify additional changes to farm practices that may help to mitigate the risk of transmission. This review will provide agencies with a comprehensive summary of the scientific literature on mitigation of disease transmission between wildlife and cattle and to identify lacunae in published research.

    virus [inter quantile range (IQR)] of all the cattle farms during spring, summer, and autumn for 17 years period were 16 [13-17], 15 [13-16] and 40 [38-42] days respectively, when using microclimatic temperatures. These estimated EIP values were much shorter compared to EIP estimated using DMI...... temperatures for the same periods of spring (29 [27-30]), summer (21 [19-24]), and autumn (56 [55-58]) days respectively. For the summer period, we observed a large area where farms with shorter EIP for Schmallenberg virus were grouped together, comprising southern Funen and associated islands, Lolland....... The objective of this study was to quantify the variation of EIP of Schmallenberg virus among Danish cattle farms and identify possible spatial patterns of the EIPs. Methods: We quantified 21 different land cover classes within a 500 meter radius of all cattle farms in Denmark (N=22092) using CORINE land cover...

    Bovine tuberculosis is a bacterial disease caused by Mycobacterium bovis in livestock and wildlife with hosts that include Eurasian badgers (Meles meles), brushtail possum (Trichosurus vulpecula), and white-tailed deer (Odocoileus virginianus). Risk-assessment efforts in Michigan have been initiated on farms to minimize interactions of cattle with wildlife hosts but research onM. bovis on cattle farms has not investigated the spatial context of disease epidemiology. To incorporate spatially explicit data, initial likelihood of infection probabilities for cattle farms tested for M. bovis, prevalence of M. bovis in white-tailed deer, deer density, and environmental variables for each farm were modeled in a Bayesian hierarchical framework. We used geo-referenced locations of 762 cattle farms that have been tested for M. bovis, white-tailed deer prevalence, and several environmental variables that may lead to long-term survival and viability of M. bovis on farms and surrounding habitats (i.e., soil type, habitat type). Bayesian hierarchical analyses identified deer prevalence and proportion of sandy soil within our sampling grid as the most supported model. Analysis of cattle farms tested for M. bovisidentified that for every 1% increase in sandy soil resulted in an increase in odds of infection by 4%. Our analysis revealed that the influence of prevalence of M. bovis in white-tailed deer was still a concern even after considerable efforts to prevent cattle interactions with white-tailed deer through on-farm mitigation and reduction in the deer population. Cattle farms test positive for M. bovis annually in our study area suggesting that the potential for an environmental source either on farms or in the surrounding landscape may contributing to new or re-infections with M. bovis. Our research provides an initial assessment of potential environmental factors that could be incorporated into additional modeling efforts as more knowledge of deer herd

    Little is published on risk factors associated with bovine brucellosis in Pacific island communities. The 2009 re-emergence of bovine brucellosis in Fiji enabled us to do an interview-based questionnaire survey of 81 farms in the Wainivesi locality of the Tailevu province on the main island of Fiji to investigate what risk factors could have played a role in the re-emergence of the disease. The survey was conducted on 68 farms that had no positive cases of bovine brucellosis and on 13 farms in the same area where cattle had returned a positive result to the Brucella Rose Bengal test. Descriptive statistical methods were used to describe the demographic data while univariate analysis and multivariate logistic regression were used to evaluate the association between the selected risk factors and the presence of brucellosis on the farms at the time of the outbreak. The demographics of Fijian dairy farms are presented in the article and the biosecurity implications of those farming systems are discussed. Two risk factors were strongly associated with farms having brucellosis, and these were history of reactor cattle to brucellosis and or bovine tuberculosis on the farm (OR = 29, P ≤ 0.01) and farms that practised sharing of water sources for cattle within and with outside farms (OR = 39, P ≤ 0.01). Possible reasons why these were risk factors are also discussed. The potential risks for human health was also high as the use of personal protective equipment was low (15%). A high proportion of farmers (62%) could not recognise brucellosis thus contributing to the low frequency of disease reports (44%) made. The article also highlights other important risk factors which could be attributed to farming practices in the region and which could contribute to public health risks and the re-emergence of diseases.

    The objectives of the present study were to isolate Beauveria bassiana strains from cattle farms soils, to analyze the phylogenetic relationships among the isolated fungi strains, and to determine the acaricidal effect of B. bassiana isolates on Rhipicephalus microplus engorged ticks, resistant or susceptible to chemical acaricides. Six strains of Beauveria bassiana were obtained and isolated from cattle farms soils by Galleria bait method in Mexican tropics and the acaricidal effect was assessed against 2 populations of R. microplus ("Media Joya" resistant strain or "CLAR" susceptible strain to chemical acaricides) using the adult immersion test. The BbV03 strain produced an 86.7% and a 60% of mortality on resistant and susceptible ticks on day 20, respectively; whereas the mortality scored with the BbV04 strain was 66.7% and 53.5% on resistant and susceptible ticks at the same day, respectively. The BbV03 and BbV04 strains reduced egg-laying on both R. microplus populations. There were not statistical differences in the acaricidal effect of B. bassiana strains, between the R. microplus susceptible or resistant populations (P > 0.05). The BbV03 strain was the most virulent against R. microplus with a LC50 of 2 x 107 and a LC99 of 7 x 108 conidia/ml. We found that the 6 B. bassiana isolated were clustered into the same clade with other previously reported B. bassiana strains (from GenBank); however, they were separated into 3 different sub-clades. This study shows that some B. bassiana strains might be a promising coadjuvant alternative for biological tick control, including those that are resistant to chemical acaricides. Beauveria bassiana is present in the pastures of tropic cattle farms and there are genetic variations between members of the bassiana specie that are living in this ecosystem. This last showed that B. bassiana might play an important roll in the natural control of R. microplus at paddocks of cattle farms.

    The aim of this study is to evaluate different aspects regarding culled cattle and to suggest operating procedures for their correct management. Information collected in Piedmont region allowed for an assessment of the number of cattle put down on the farm, a quantification of slaughters performed in urgency and emergency (SUS/SES) and a headcount of those which died during farming. The survey highlighted the limited use of euthanasia or putting down compared to the number of cases of SUS/SES which were approximately ten times higher. If cattle displays severe health problems, such as a multifactorial disease like downer cow, the farmer has to decide rapidly the treatment to avoid cattle distress. A checklist has been developed and a flow chart has been revised to assist farmers and vets to quicken the decision-taking process and to manage the cattle in a more efficient manner. During this study a number of different problems have been stressed out. Particularly, the shortcomings in the training of operators commissioned to manage the animals, the inadequacy of structures used for the sheltering and slaughter of bovines on the farm, and differences in the operating procedures for culled cattle across the territory. From the obtained results, we can conclude that it is necessary to adopt a transversal approach, so that the information regarding these animals (welfare, health status, drug treatments and destination) will be uniform and adequate during all the steps of production, to ensure animal welfare and food safety.

    2015-07-01

    The aim of this study was evaluate the relationship between the intensity of milk production for a wide range of Portuguese commercial cattle farms and NH3 and greenhouse gas (GHG) emissions from manure management and enteric fermentation. A survey was carried out at 1471 commercial dairy cattle farms (Holstein-Friesian) and the NH3, N2O and CH4 emissions at each stage of manure management were estimated as well as CH4 losses from enteric fermentation. Gaseous emissions were estimated by a mass flow approach and following the recommendations of IPCC guidelines. The manure management and enteric fermentation in a typical Portuguese cattle farm contributes with 7.5±0.15 g N/L milk produced as NH3 and 1.2±0.22 kg CO2 equivalent per litre of milk as GHG. Increasing milk production will significantly reduce NH3 and GHG emissions per litre of milk produced. It can be concluded that a win-win strategy for reducing NH3 and GHG emissions from dairy cattle farms will be the increase of milk production on these farms. This goal can be achieved by implementing animal breeding programs and improving feed efficiency in order to increase productivity. (Author)

    Full Text Available Even though biogas technology has been introduced in Indonesia since 1990’s and having the potential, the rate of biogas adoption in Indonesia runs slowly. It is important to understand factors encouraging or discouraging potential adopters to build biogas plant. The development of livestock sector especially cattle farming in Indonesia can be seen as the opportunity to increase the rate of biogas adoption. This study investigated the factors affecting households of cattle farmer to adopt or not to adopt biogas technology. A cross-sectional research survey was carried out by using structured questionnaires as the primary tool to collect data from both biogas adopters and non biogas adopters in Pati regency, Indonesia. Socioeconomic characteristic of potential biogas adopters plays an important role to ensure the adoption of biogas technology sustainable. Socioeconomic characteristic regarding having high social status determines individual to adopt biogas relatively earlier than other members of a social system. Having high income and education enables traditional farmers to finance biogas plant by their own money or access aid from the government or other agencies. Among other attributes of innovation, relative advantage of installing biogas plant is the most determinant attribute to speed the rate of biogas adoption. Having biogas plant was perceived as better option and generated more benefits compared to previous technology or method.

    Full Text Available Formulation of exclusively organic diets that meet maintenance and production requirements of dairy cattle is a major limitation to production of premium organic products of animal origin. This study was therefore carried out to assess the use and availability of feed resources and the coping strategies used by farmers to overcome dry season feed shortages on 64 smallholder certified organic pineapple farms. Data was collected using semi-structured questionnaires and two focus group discussions. Majority of households were headed by males (62.9% while average age of respondents was 42.5 years. Farmers allocated more land (P<0.05 to organic pineapple production compared to livestock. Beside dairy cattle, farmers also kept chickens, goats and pigs. Tethering was the commonest cattle management system. Fifty three percent of respondents reported using both natural pastures and crop residues as major dairy cattle feed resources while only 19% reported using elephant grass. Banana peels (25.1% and sweet potato vines (24.7% were the most important crop residues fed to cattle. Farmers reported high cost of concentrates and scarcity of feeds as their biggest challenges in dairy cattle production. Of the respondents, 51.4% conserved feed for their cattle as fodder banks. As a coping strategy to feed shortages, majority (42.9% of farmer scavenged for feed resources from both organic certified and nonorganic neighbouring farms which is contrary to organic livestock farming standards. It was, therefore, concluded that management of livestock feeding in the study area fell short of the requirements for organic livestock feeding standards. Research to develop strategies that can use alternative on-farm feed resources through ensiling organic pineapple wastes during the dry season is recommended as a long term strategy to address feed challenges for organic livestock farmers.

  4. E. coli O157 on Scottish cattle farms: Evidence of local spread and persistence using repeat cross-sectional data

    Science.gov (United States)

    2014-01-01

    Background Escherichia coli (E. coli) O157 is a virulent zoonotic strain of enterohaemorrhagic E. coli. In Scotland (1998-2008) the annual reported rate of human infection is 4.4 per 100,000 population which is consistently higher than other regions of the UK and abroad. Cattle are the primary reservoir. Thus understanding infection dynamics in cattle is paramount to reducing human infections. A large database was created for farms sampled in two cross-sectional surveys carried out in Scotland (1998 - 2004). A statistical model was generated to identify risk factors for the presence of E. coli O157 on farms. Specific hypotheses were tested regarding the presence of E. coli O157 on local farms and the farms previous status. Pulsed-field gel electrophoresis (PFGE) profiles were further examined to ascertain whether local spread or persistence of strains could be inferred. Results The presence of an E. coli O157 positive local farm (average distance: 5.96km) in the Highlands, North East and South West, farm size and the number of cattle moved onto the farm 8 weeks prior to sampling were significant risk factors for the presence of E. coli O157 on farms. Previous status of a farm was not a significant predictor of current status (p = 0.398). Farms within the same sampling cluster were significantly more likely to be the same PFGE type (p Scottish E. coli O157 paves the way for future research into the mechanisms of transmission which should help with the design of control measures to reduce E. coli O157 from livestock-related sources.

    Q fever is a zoonotic disease caused by Coxiella burnetii, a bacterial agent for which ruminants are the main reservoir. An extensive cross-sectional study to determine the seroprevalence of and associated risk factors for Q fever was performed in dairy and mixed (dairy-beef) cattle herds in Ecuador. A total of 2668 serum samples from 386 herds were analyzed using an ELISA. In addition, a questionnaire with 57 variables related to management, feeding, facilities, biosecurity and animal health was completed for every cattle farm. A Generalized Estimating Equations model was used to determine the factors associated with C. burnetii seropositivity. The true prevalence of C. burnetii seropositivity in dairy and mixed cattle from Ecuador reached 12.6% (CI95%: 11.3-13.9%). The herd prevalence was 46.9% (181/386) (CI95%: 41.9-51.9%), and the within herd prevalence ranged between 8% and 100% (mean: 25.0%; Q1: 12.5%, Q2: 25.0%, Q3: 37.5%). Four factors were included in the GEE model for C. burnetii seropositivity: age of the cattle (OR: 1.01; CI95%: 1.006-1.014), feeding of calves with milk replacers (OR: 1.94; CI95%: 1.1-3.3), bovine respiratory syncytial virus seropositivity (OR: 1.54; CI95%: 1.1-2.3), and disinfection of the umbilical cord (OR: 0.60; CI95%: 0.4-0.9).

  8. Animal movement network analysis as a tool to map farms serving as contamination source in cattle cysticercosis

    Directory of Open Access Journals (Sweden)

    Samuel C. Aragão

    Full Text Available ABSTRACT: Bovine cysticercosis is a problem distributed worldwide that result in economic losses mainly due to the condemnation of infected carcasses. One of the difficulties in applying control measures is the identification of the source of infection, especially because cattle are typically acquired from multiple farms. Here, we tested the utility of an animal movement network constructed with data from a farm that acquires cattle from several other different farms to map the major contributors of cysticercosis propagation. Additionally, based on the results of the network analysis, we deployed a sanitary management and drug treatment scheme to decrease cysticercosis’ occurrence in the farm. Six farms that had commercial trades were identified by the animal movement network and characterized as the main contributors to the occurrence of cysticercosis in the studied farm. The identification of farms with a putative risk of Taenia saginata infection using the animal movement network along with the proper sanitary management and drug treatment resulted in a gradual decrease in cysticercosis prevalence, from 25% in 2010 to 3.7% in 2011 and 1.8% in 2012. These results suggest that the animal movement network can contribute towards controlling bovine cysticercosis, thus minimizing economic losses and preventing human taeniasis.

    During composting, the composition of microbial communities is subject to constant change owing to interactions with fluctuating physicochemical parameters. This study explored the changes in bacterial and fungal communities during cattle farm waste composting and aimed to identify and prioritize the contributing physicochemical factors. Microbial community compositions were determined by high-throughput sequencing. While the predominant phyla in the bacterial and fungal communities were largely consistent during the composting, differences in relative abundances were observed. Bacterial and fungal community diversity and relative abundance varied significantly, and inversely, over time. Relationships between physicochemical factors and microbial community compositions were evaluated by redundancy analysis. The variation in bacterial community composition was significantly related to water-soluble organic carbon (WSOC), and pile temperature and moisture (p composts. © 2017 The Authors.

    Full Text Available In order to get a reliable estimate of brucellosis prevalence in Eritrean dairy cattle, a cross-sectional study was carried out in 2009. The survey considered the sub-population of dairy cattle reared in modern small- and medium-sized farms. Samples were screened with the Rose Bengal test (RBT and positive cases were confirmed with the complement fixation test (CFT. A total of 2.77%(417/15 049; Credibility Interval CI: 2.52% – 3.05% of the animals tested in this study were positive for antibodies to Brucellaspecies, with a variable and generally low distribution of positive animals at regional level. The highest seroprevalence was found in the Maekel region (5.15%; CI: 4.58% – 5.80%, followed by the Debub (1.99%; CI: 1.59% – 2.50% and Gash-Barka (1.71%; CI: 1.34% – 2.20% regions. Seroprevalence at sub-regional levels was also generally low, except for two sub-regions of Debub and the sub-region Haicota from the Gash-Barka region. Seroprevalence was high and more uniformly distributed in the Maekel region, namely in the Asmara, Berik and Serejeka sub-regions. Considering the overall low brucellosis prevalence in the country, as identified by the present study, a brucellosis eradication programme for dairy farms using a test-and-slaughter policy would be possible. However, to encourage the voluntary participation of farmers to the programme and to raise their awareness of the risks related to the disease for animals and humans, an extensive public awareness campaign should be carefully considered, as well as strict and mandatory dairy movement control.

Livestock diseases (29% of the respondents), high cost of drugs (18.21%), weak veterinary extension (15.18%), inadequate grazing (13.60%), inadequate water (13.54%), and livestock thefts (10.44%) were the major livestock health and production constraints identified. The number of diseases reported varied (Pdomestic chicken, donkeys, and guinea fowls, respectively. Seven (19.4%) of the 36 diseases including rabies and foot and mouth disease were those listed by the OIE. Thirty-four percent of the respondents rated bovine dermatophilosis as the most important livestock disease. Respondents rated, in descending order, other diseases including tick borne diseases (21%); a previously unreported disease, "Magwiriri" or "Ganda renzou" in vernacular (14%); mastitis (11%); parafilariosis (11%); and blackleg (9%). Cattle skin samples from "Magwiriri" cases had Besnoitia besnoiti parasites. Overall, this study revealed factors and diseases that limit livestock production in Zimbabwe and are of global concern; in addition, the study showed that the skin diseases, bovine dermatophilosis and besnoitiosis, have recently emerged and appear to be spreading, likely a consequence of ectoparasite control demise in smallholder farming areas of Zimbabwe over the last 15 years.

    Full Text Available To satisfy Indian consumers’ rising demand for milk products, Indian breeders will have to boost their production rapidly, especially through improved feeding practices. Many experts point out that currently used crop by-products will not be sufficient to meet increasing feed requirements from cow and buffalo herds and that it will be necessary to turn to grains such as wheat and maize. But other experts think that grain will not be enough and that the increasing animal consumption of grain will affect human consumption, unless India decides on massive grain imports, putting pressure on the world grain market. The present survey carried out in two districts of Haryana showed that grain was not an essential feed for cattle and buffaloes, and that improving cotton and mustard by-products, and green fodder had great potential. A second finding was that wealthier farmers tended to underuse the genetic potential of milk cows and buffaloes. Moreover, biotechnical management of the herd, in particular the feeding system, was closely related to the socioeconomic management of the family farming system; family strategies aimed at ensuring sufficient milk production for the family in larger farms and to provide a regular income in smaller ones. This paper also stressed out the need to design, implement, and monitor development programs that integrate sociocultural and, especially, gender issues, to facilitate technological innovation with respect to forage storage.

    In many developing countries, milk production varies greatly according to farm size, cattle breed, and milking practices. However, production systems often are dominated by smallholder farms. Therefore, relatively small volumes of milk are delivered daily from numerous farms to intermediate cooperatives which supply industrial units. This paper argues that in such two-stage dairy chains, milk quality could be improved by focusing on farming practices rather than on the testing of individual deliveries. Indeed, it is difficult to analyze their quality due to technical, economic, and logistic limitations. The objective of this study is to link on-farm practices with milk chemical quality parameters (fat and protein) and hygienic quality criteria (Aerobic Plate Count, APC and Coliforms). Cattle management practices were monitored monthly over one year on 23 farms located on an irrigation scheme in Morocco. 276 milk samples were analyzed. The monthly variability of milk quality parameters was then characterized. Results show that average cow milk chemical parameters vary within a normal range. They remain primarily linked to the genetic type of cows, the lactation stage, and the conversion of feed concentrates' net energy into milk. Overall milk hygienic quality was poor (APC and Coliforms counts were 100 fold international norms), due essentially to a lack of hygiene and inadequate milking conditions (hands, udder, and teat washing, type of bucket used, dirtiness of cows...). It is suggested that a close monitoring of herd management practices may allow the indirect control of milk quality parameters, thereby avoiding costly analyses of numerous smallholder milk deliveries.

    Proper cattle-handling techniques (stockmanship) are important to ensure calm animals and a safe work environment for dairy workers on farm. The objectives of this study were to (1) assess Minnesota dairy herd owners' attitudes toward stockmanship, its perceived importance for cow comfort and worker health, and the establishment of calm cattle movement; and (2) identify current resources and methods of stockmanship training on Minnesota dairy farms. A stratified-random sample of Minnesota dairy farmers were contacted via mail to participate in a 28-question survey. One hundred eight bovine dairy producers participated. Most commonly, respondents learned their cattle handling skills from family members (42.6%) and 29.9% of producers had participated in previous stockmanship training. Producers thought that the skill of the human handler was the most important factor in establishing good cattle flow. Cattle-handling techniques was the third most common topic for new-employee orientation after training in milking parlor protocols and milking parlor disinfection. Time limitations and language barrier were considered serious challenges for worker training. Work-related injuries were responsible for lost work days in the previous year in 13.3% of dairy herds and 73.3% of those injuries occurred while working with cattle. Producers perceived that cattle-related injuries were predominantly the handler's fault: either because of not paying enough attention to the animal or due to poor cattle handling skills. Facility design was considered the least important for the occurrence of worker injuries. Although no causal inference can be made, herds that had workers who had previously participated in stockmanship training had a 810 ± 378 kg (mean ± standard error of the mean) higher rolling herd average than those that did not, even after adjusting for herd size and bulk tank somatic cell count. However, 50% of respondents were not interested in attending future stockmanship

    The prevalence of bovine fasciolosis in Denmark is increasing but appropriate guidelines for control are currently lacking. In order to help develop a control strategy for liver fluke, a risk factor study of farm management factors was conducted and the utility of bulk tank milk (BTM ELISA) as a tool for diagnosis in Danish dairy cattle farms was assessed. This case-control study aimed to identify farm-level risk factors for fasciolosis in Danish dairy farms (> 50 animals slaughtered in 2013) using two diagnostic methods: recordings of liver condemnation at slaughter, and farm-level Fasciola hepatica antibody levels in BTM. A case farm was defined as having a minimum of 3 incidents of liver condemnation due to liver fluke at slaughter (in any age group) during 2013, and control farms were located within 10 km of at least one case farm and had no history of liver condemnation due to liver fluke during 2011-2013. The selected farmers were interviewed over telephone about grazing and control practices, and BTM from these farms was collected and analysed by ELISA in 2014. The final complete dataset consisting of 131 case and 63 control farms was analysed using logistic regression. Heifers grazing on wet pastures, dry cows grazing on wet pastures, herd size, breed and concurrent beef cattle production were identified as risk factors associated with being classified as a case farm. With the categorised BTM ELISA result as the response variable, heifers grazing on wet pastures, dry cows grazing on wet pastures, and purchase of cows were identified as risk factors. Within the case and control groups, 74.8 and 12.7% of farms were positive for fasciolosis on BTM ELISA, respectively. The differences are likely to be related to the detection limit of the farm-level prevalence by the BTM ELISA test, time span between slaughter data and BTM, and the relatively low sensitivity of liver inspection at slaughter. Control of bovine fasciolosis in Denmark should target heifers and

    Full Text Available A study was carried out on the Opkara (Benin cattle farm on 64 cattle of four different breeds (16 individuals per breed from June to December 2016. During this study, three tick species were found in different numbers, Amblyomma variegatum (732, Rhipicephalus microplus (8079, and Hyalomma spp. (208, with parasitic intensity of 11.90, 126.23, and 3.25, respectively. The interracial comparison of the tick infestation between the cattle showed a significant difference (P<0.001. However, Girolando was more infested than all the cattle breeds. Infestation of A. variegatum, R. microplus, and Hyalomma spp. on the Girolando was, respectively, 19.43 ± 2.71, 171.25 ± 23.50, and 7.12 ± 0.63, but the Borgou were less infested. Borgou breed females were more infested by A. variegatum (4.41 ± 1.14 than females Girolando (4.20 ± 0.90. The Crossbred and Azawak females were less infested (P<0.01. The mean of A. variegatum on Borgou, Azawak, Crossbred, and Girolando calves was 1.29 ± 0.35, 0.66 ± 0.26, 1.37 ± 0.37, and 2.25 ± 0.48 (P<0.01, respectively. The results of this study can be exploited to include genetic and nongenetic approaches to tick control.

    Full Text Available The study was aimed to explore the role of cooperativism in dairy cattle farming in Getasan village,Semarang Regency, Central Java Province. Spearman Rank Correlation test was used to determine therelationship between cooperativism and the performance of dairy cattle farming. Based on the results ofthe Spearman Rank correlation test, feeds and feeding practices were significantly correlated withsharing of knowledge and information and sharing of resources. However, no significant relationshipwas found between participation in decision making and feeds and feeding practices. Meanwhile, therewere significant relationships amog sharing of knowledge and information, sharing of resources, andparticipation in decision making and milk production in Getasan Village. The dairy health asperformance indicator of dairy cattle farming, sharing of knowledge and information was the onlysignificant factor. Sharing of resources and participation in decision making had no significantrelationship with dairy health. As regards marketing, the test showed that sharing of knowledge andinformation, sharing of resources, and participation in decision making were significantly relatedfactors. This study indicated that cooperativism may provide opportunities for farmers to accessservices, information and resources that will allow them to improve their capacities in these areas. Thisstudy also proposed some recommendations that the cooperatives should promote activities encouraginggreater cooperation and mutual understanding among the members. Skills trainings and education forempowerment should be conducted to encourage participation in decision making.

  2. Reproductive Disorders and Leptospirosis: A Case Study in a Mixed-Species Farm (Cattle and Swine

    Full Text Available Animal leptospirosis, exempt in rodents, manifests as peculiar biology where the animal can function, simultaneously or not, as a susceptible host or reservoir. In the first case, clinical symptoms are likely. In the second case, infection is subclinical and manifestations are mild or absent. Mild clinical symptoms encompass reproductive failure in production animals for host-adapted Leptospira sp. serovars. This work presents a study on Leptospira sp. infection in a mixed-species (bovine and swine farm with documented reproductive disorders in the cattle unit. A long calving interval (above 450 days was the hallmark observed in cows. Some cows (2/26 tested presented a high titre of antibodies against Leptospira sp. serogroup Sejroe, but the overall within-herd prevalence was low (11.5% and 7.7% for cut-off titres of 1:30 and 1:100, respectively. The in-herd prevalence of leptospirosis in the sow unit (determined for 113/140 animals was high when using a lowered cut-off threshold (32.7% vs. 1.8% for cut-off titre of 1:30 and 1:100, respectively. In this unit, the most prevalent serogroup was Autumnalis. The final diagnostic confirmation of Leptospira sp. maintenance within the farm was obtained through detection by PCR of Leptospira sp. DNA in an aborted swine litter. Despite the fact that a common causative infective agent was diagnosed in both species, the direct link between the two animal units was not found. Factors such as drinking from the same water source and the use of manure prepared with the swine slurry might raise suspicion of a possible cross-contamination between the two units. In conclusion, this work suggests that leptospirosis be included in the differential diagnosis of reproductive disorders and spontaneous abortions in production animals and provides data that justify the use of a lowered threshold cut-off for herd diagnosis.

    Full Text Available Aim: This study was carried out to investigate the genetic analysis of reproductive performance of Frieswal cattle at Military Farm, Ambala. Materials and Methods: A total number of 3005 lactation records of 1147 Frieswal cows over a period of 15 years extending from 1993 to 2007 were used to study at Military Dairy Farm, Ambala. The study period was divided into 5 period of 3 years each. The average performances of reproduction traits, effect of genetic and non-genetic factors were analyzed, and estimation of genetic and phenotypic parameters of reproduction traits was undertaken. Results: The age at first calving (AFC differed significantly across the periods of calving. The AFC was lowest during the third period (1999-2001 and longest in the first period (1993-95. The effect of season and period of calving, lactation order and regression of AFC on dry period, calving interval and service period was highly significant. The effect of sire was non-significant. The heritability estimates were low for almost all the traits under study. The service period had a high genetic correlation with dry period and calving interval. The dry period also found to have a low genetic correlation with calving interval in Frieswal cows. Service period had a high phenotypic correlation with dry period and very high with a calving interval. The phenotypic correlation between the dry period and calving interval was recognized high. Conclusions: Low heritability estimate for the reproduction traits indicates that there is a very little additive genetic variance in these traits, and individual selection will not be helpful for improving them. Improvement may be brought through better feeding and management of cows by reducing the environmental variability.

  4. What is the benefit of organically-reared dairy cattle? Societal perception towards conventional and organic dairy farming

    Full Text Available During the last years, current systems in agriculture and food production have been topic in public discussions. Especially modern animal husbandry seems not to match consumers’ or societal needs any longer. This paper concentrates on the society’s perspective regarding dairy farming in general and diverting perceptions and expectations with respect to dairy cattle either reared organically or reared conventionally. It aims to give orientation to farmers as well as policymakers about the societal point of view of dairy farming.Six focus groups were carried out in three German cities to capture the scope of opinions and expectations among the population. Three of those groups consisted of participants buying mainly organic food while the other three comprised citizens buying mainly conventional food.With respect to society’s perception of today’s dairy farming results showed that participants put emphasis on the following topics: the space for each cow was considered as insufficient and not species-appropriate, assumed application of medications as too high, and in particular the prophylactic use of antibiotics as problematic.Asked about perceived differences between organic versus conventional farming it became obvious that organic in contrast to the conventional farming was perceived as more species-appropriate. More or less, all previously criticized aspects seem to be regarded as irrelevant in organic farming. Some participants showed a very romantic view of organic dairy farming. The most critical point was an assumed high rate of rogue traders among organic farmers.

    Biogas is a promising renewable fuel, which can be produced from a variety of organic raw materials and used for various energetic purposes, such as heat, combined heat and power or as a vehicle fuel. Biogas systems implementation are, therefore, subjected to several support measures but also to several constraints, related with policy measures on energy, waste treatment and agriculture. In this work, different policies and policy instruments, as well as other factors, which influence a potential expansion of Portuguese biogas systems are identified and evaluated. The result of this analysis shows that the use of the cattle manure for biogas production is still far from its potential. The main reason is the reduced dimension of the Portuguese farms, which makes biogas production unfeasible. Various options are suggested to increase or improve biogas production such as co-digestion, centralized plants and modular plants. Horizontal digesters are the most suitable for the typical Portuguese plant size and have the advantage of being also suitable for co-digestion due to the very good mixing conditions. Mesophilic anaerobic digestion due to a more robustness, stability and lower energy consumption should be the choice. The recent increase in the feed-in tariffs for the electricity production based on anaerobic digestion biogas is seen as a political push to this sector. (author)

    Full Text Available The aim of the study was to determine the presence of antibodies against Neospora caninum and its DNA in blood samples from bovine females from the northern region of the state of Veracruz, Mexico. A cross-sectional epidemiological study was carried out in 13 municipalities, with a sample size of 821 animals. Blood and serum samples were analyzed through ELISA and PCR, respectively. Overall prevalence was 20.8 %; the highest specific prevalences were obtained in breeding cows (27.4 %, crossbred cows (20.9 %, second-calving cows (23.2 %, three year-old cows (20.6 % and cows with abortion history (20 %. The risk factors associated with seropositivity were dairy cattle (OR = 1.9; IC95 %: 1.1-3.4 and dog presence in the farms (OR = 5.3; IC95 %: 1.3-22.3. The presence of N. caninum DNA was demonstrated in 4 out of 12 blood samples tested, which evidenced the existence of active infection. In conclusion, there were risk factors associated with bovine neosporosis, which proved the existence of active infection by N. caninum in cows from the state of Veracruz, Mexico.

    Agriculture is one of the largest anthropogenic sources of greenhouse gases (GHGs), with dairy and beef production accounting for nearly two-thirds of emissions. Several recent papers suggest that dung beetles may affect fluxes of GHGs from cattle farming. Here, we put these previous findings into context. Using Finland as an example, we assessed GHG emissions at three scales: the dung pat, pasture ecosystem, and whole lifecycle of milk or beef production. At the first two levels, dung beetles reduced GHG emissions by up to 7% and 12% respectively, mainly through large reductions in methane (CH4) emissions. However, at the lifecycle level, dung beetles accounted for only a 0.05-0.13% reduction of overall GHG emissions. This mismatch derives from the fact that in intensive production systems, only a limited fraction of all cow pats end up on pastures, offering limited scope for dung beetle mitigation of GHG fluxes. In contrast, we suggest that the effects of dung beetles may be accentuated in tropical countries, where more manure is left on pastures, and dung beetles remove and aerate dung faster, and that this is thus a key area for future research. These considerations give a new perspective on previous results, [corrected] and suggest that studies of biotic effects on GHG emissions from dung pats on a global scale are a priority for current research.

    1999-01-01

    The present study was designed to identify problems that lower the productivity of imported dairy cattle in Morocco. For this purpose, a comprehensive survey was carried out on 8 small-holder farms over a period of two years. Analysis of the data collected indicated that in most of the herds reproductive performance was adequate (calving intervals ranging from 338 ± 11 to 420 ± 31 and services to conception ranging from 1.14 ± 0.13 to 1.91 ± 0.3), but the animals had difficulty in meeting the nutrient requirements for milk production. Although some farmers provided supplements to their animals they were either expensive or not available at the required time. One possible way of alleviating the problem was the introduction of a fish by-product into the dairy cattle ration. Two experiments were conducted, one at the Institute experimental farm and the other at a private farm selected for the survey. In both experiments, fish silage blocks were incorporated into the ration of dairy cattle in replacement of an equal amount of the most commonly used supplements. The introduction of fish silage blocks in the ration did not affect their intake or body condition. In addition, the yield and quality of the milk were maintained. This substitution allowed the farmer to utilize by-products from the fish industry which are readily available and less costly than most conventional supplementary feeds. It is concluded, that the proposed utilization of fish silage blocks will reduce the production costs and improve the economic efficiency of the small-holder farms. (author)

    Paratuberculosis is an economically important disease of dairy cattle caused by Mycobacterium avium subsp. paratuberculosis (Map). The role of nonruminant, nondomestic animals in the epidemiology of paratuberculosis in cattle is unclear. To examine nonruminant, nondomestic animals for the presence of Map, 25 feral cats, nine mice (species unknown), eight rabbits (Sylvilagus floridanus), six raccoons (Procyon lotor), and three opossums (Didelphis virginiana) were collected from a mid-western dairy with known Map-infected cattle. Mycobacterium avium subsp. paratuberculosis was isolated from the mesenteric lymph node from seven of 25 (28%) feral cats. Ileum was culture-positive for three of these seven cats, and an isolation of Map was also made from the ileum of one of nine (11%) mice. Tissue samples from other species were negative as determined by Map culture; microscopic lesions consistent with paratuberculosis were not seen in any animal. Restriction fragment polymorphism analysis of isolates from cats and dairy cattle suggest interspecies transmission. The means by which interspecies transmission occurred may be through ingestion of Map-contaminated feces or waste milk or through ingestion of Map-infected prey. Shedding of Map from infected cats was not evaluated. The epidemiologic role of Map-infected feral cats on dairy farms requires further investigation.

    A study of the traditional cattle production systems in the Western Highlands of Cameroon was carried out between August 1994 and September 1997. Fifty two cows selected from 14 farms in 4 locations were monitored monthly. Data were collected on calf and dam weight, dam's body condition, milk offtake and forage quality. Reproductive performance was monitored by measuring progesterone levels in milk sampled weekly. Crude protein content of grazed pastures rose from 12.5% in July to 14.5% in October and declined steadily to reach 4.5% in February. With such a decline in forage quality during the dry season, cows are unable to obtain their nutrient needs, thus productivity was low. Body condition score declined from medium (5.6) at calving to upper low (4.5) 4 months after the initiation of milk offtake. Body weight of cows decreased by nearly 14% during the same period. The interval between calving to first progesterone rise, calving to conception, and inter-calving intervals were 172 ± 116, 185 ± 106 and 448 ± 86 days, respectively. Milk offtake averaged 1.29 ± 0.44 kg/cow/day for a lactation length of 10.5 months. A significant effect of season was detected in milk offtake (P <0.001), body condition score (P <0.05), body weight of cows (P <0.05), intervals from calving to first progesterone rise (P <0.05), calving to conception (P <0.05) and inter-calving interval (P <0.01). Supplementary feeding during the dry season and early lactation to cover the nutrient requirements of the cows in the traditional production system of Western Highlands of Cameroon is recommended and forms the purpose of the second part of this study which is now underway.

    Full Text Available The concentration of some chemical components was characterized, in soils of an agro- ecosystem of a cattle farm with different reliefs, one located in the plains and another in a hilly area. The statistical descriptive variables were calculated for organic matter, pH, P2O5, K2O, Cu, Zn, Fe and Mn; by means of a t- Student test for independent samples, the variables were compared among the rainy and dry seasons. In the agro-ecosystem of the plains the 24.5, 75.4, 20.7, 41.5, 33.9 and 56.6 % of the samples were below the critical limit for organic matter, P2O5, K2O, Cu, Mn and Zn, respectively. In the hilly region the concentrations of the organic matter and the mentioned chemical elements were deficient in a 25, 80, 42.5, 7.5 and 25 %, and 2.5 % in the samples of Fe. They were significant levels of Cu for the rainy season, while in the Mn was significant in the dry season for the agro-ecosystem of the plains, while in the hilly region there were small significant values in the Cu, Fe and Mn in the dry season, on the contrary of the P2O5 that showed small values during the rainy season. It concludes that independent in the agro-ecosystems that there were deficiencies in a percent of the soil samples, equally significant variation existed in the levels of the minerals in conjunction with the season.

    The objective of this study was to validate four key farmer performance indicators (KFPI), identified in a previous study, as indicators of on-farm cattle welfare incidents in Ireland, through comparison of the distribution of these KPFIs in the national herd (n=109,925) and in case herds (n=18), where welfare incidents were previously studied. The KFPIs identified were late registrations, and exits from the herd by on-farm burial, by moves to knackeries and by moves to 'herd unknown'. Data were extracted from two Department of Agriculture, Food and the Marine databases for the national herd and the case herds. All four KFPIs differed significantly between the case herds and the national herd, and one further KFPI was identified, namely moves to factories. The data for these KFPIs are routinely stored on national databases, which were established in order to comply with Regulation (EC) 1760/2000. Based on the results obtained in this study, it may be possible in the future to use routine data capture to improve strategy towards on-farm animal welfare. At this point, however, based on calculated specificities and sensitivities, none of these five KFPIs, at the cut-offs investigated and using several combinations, are able to distinguish herds with and without on-farm animal welfare problems at an accuracy suitable for routine national use in Ireland.

    Two studies were conducted in the peri-urban area of Dakar to collect baseline information on feeding, milk production, reproduction, body weight and body condition (Phase I), and to examine the influence of supplementation with local by-products on productive and reproductive parameters of indigenous cattle in traditional smallholder farms (Phase II). Baseline data collected from smallholder farms between 1994 and 1996 indicated delayed first calving, long calving intervals, decreasing body condition score (BCS) and body weight and low milk yields as major problems associated with cattle productivity in the region. Fertility was related to forage availability; animals showed high fertility after the rainy season and low fertility during the dry season. Supplementation during the critical period of the dry season using agro-industrial by-products (brewer's grains, molasses, groundnut cake, oyster shell and salt) had beneficial effects on productivity. Supplementation reduced loss in body weight and body condition, maintained milk yield and growth rate of the calves during the dry season and reduced length of 'days open' and the calving interval.

    European starlings (Sturnus vulgaris) have been implicated in the dispersal of zoonotic enteric pathogens. However, their role in disseminating antimicrobial-resistant organisms through their home range has not been clearly established. The aim of this study was to determine whether starling night roosts served as foci for spreading organisms with reduced susceptibility to antimicrobials among dairy cattle farms. Bovine faecal pats were collected from 150 dairy farms in Ohio. Each farm was visited twice (in summer and fall) between 2007 and 2009. A total of 1490 samples (10 samples/farm over two visits) were tested for Escherichia coli with reduced susceptibility to cefotaxime and ciprofloxacin. Using a spatial scan statistic, focal scans were conducted to determine whether clusters of farms with a high prevalence of organisms with reduced susceptibility to cefotaxime and ciprofloxacin surrounded starling night roosts. Faecal pats 13.42% and 13.56% of samples carried Escherichia coli with reduced susceptibility to cefotaxime and ciprofloxacin, respectively. Statistically significant (P Escherichia coli showing reduced susceptibility to cefotaxime and ciprofloxacin were identified around these night roosts. This finding suggests that the risk of carriage of organisms with reduced susceptibility to antimicrobials in cattle closer to starling night roosts was higher compared to cattle located on farms further from these sites. Starlings might have an important role in spreading antimicrobial-resistant E. coli to livestock environments, thus posing a threat to animal and public health. © 2016 Blackwell Verlag GmbH.

    The competent veterinary authorities imposed trade restrictions on affected farms. All persons who had been in contact with affected animals were advised to increase biosecurity measures (e.g. using farm-owned or disposable protective clothing. In some farms, affected animals were vaccinated against BVD to reduce clinical signs as an “emergency measure”. These measures stopped the further spread of the disease.

    Red deer can be infected with some gastrointestinal nematodes (GIN) of cattle but it is unknown to what extent. An indoor study was conducted to determine the establishment rate of cattle GIN in young deer. Five young calves and 5 young red deer were used. They were effectively treated with anthelmintics when housed and then infected 2 weeks later. After four weeks they were killed for total worm counts. Establishment rates were assessed comparing worm counts to the infective dose which were identified morphologically, and to the relative establishment rate of different species. The establishment rates (%) in cattle and deer respectively were H. contortus (8.0, 18.7, p=0.18), Ostertagia ostertagi (30.8, 0.7, p98%) of Trichostrongylus spp. were Trichostrongylus axei in both hosts and there were no differences between hosts for this species (p=0.11). In cattle >98% of Cooperia were Cooperia oncophora and the mean burden was much higher than in deer (pcattle (pcattle-origin GIN can establish in red deer. In particular, the establishment of H. contortus and T. axei could allow sufficient burdens to build up to be clinically significant.

    Full Text Available The purpose of this paper is to provide insights of the profile of the dairy farms of Central Macedonia (Greece, in terms of their milking practices. The analysis is based on data from a random sample of 123 dairy farms, obtained by means of a survey. The employment of the Categorical Principal Component Analysis on the 14 variables initially used to describe milking practices and of the Two-Step Cluster Analysis led to the grouping of the 123 farms to three clusters. Farms of the first cluster, named “Innovative”, use state-of-the-art equipment, automatic systems and innovative milking techniques (31.1% of the sample farms. “Peasant” farms (11.4% are mainly extensive, using mainly bucket plants. The third and most abundant group, the “Modernizing” farms (54.5% are use equipment of reasonable standards and some of them are on the process of renewing it. The results of a Multinomial Logit model verify that “Innovative” farms are large and achieve high yields, while the “Modernizing” ones are smaller, producing milk of lower quality and they are owned by relatively older dairy farmers. An interesting profile is depicted for “Peasant” farms, as they achieve satisfactory economic performance, combined with adequate milk quality. The analytical framework included the reduction of analysis variables to a smaller group of “dimensions”, using the Categorical Principal Component Analysis (CatPCA, based on which farms were clustered to alternative profiles, by employing a Two-Step Cluster (TSC Analysis. Differences in elements of milk quality and in the social profile of farms and farmers were examined among alternative profiles through the estimation of Multinomial Logit Models.

    Although prototypes of automatic lameness detection systems for dairy cattle exist, information about their economic value is lacking. In this paper, a conceptual and operational framework for simulating the farm-specific economic value of automatic lameness detection systems was developed and tested on 4 system types: walkover pressure plates, walkover pressure mats, camera systems, and accelerometers. The conceptual framework maps essential factors that determine economic value (e.g., lameness prevalence, incidence and duration, lameness costs, detection performance, and their relationships). The operational simulation model links treatment costs and avoided losses with detection results and farm-specific information, such as herd size and lameness status. Results show that detection performance, herd size, discount rate, and system lifespan have a large influence on economic value. In addition, lameness prevalence influences the economic value, stressing the importance of an adequate prior estimation of the on-farm prevalence. The simulations provide first estimates for the upper limits for purchase prices of automatic detection systems. The framework allowed for identification of knowledge gaps obstructing more accurate economic value estimation. These include insights in cost reductions due to early detection and treatment, and links between specific lameness causes and their related losses. Because this model provides insight in the trade-offs between automatic detection systems' performance and investment price, it is a valuable tool to guide future research and developments.

    Full Text Available The paper analyses Estonian tax structure changes during the last decade and critically assesses the current situation. The country’s tax mix is rather unique among EU countries – it has one of the highest proportions of consumption taxes in total taxes and the lowest level of capital and profit taxes. Such an unbalanced tax structure creates risks for public finances, limits revenue collection and distorts the business environment.

    Identifying and ranking cattle herds with a higher risk of being or becoming infected on known risk factors can help target farm biosecurity, surveillance schemes and reduce spread through animal trading. This paper describes a quantitative approach to develop risk scores, based on the probability of infection in a herd with bovine tuberculosis (bTB), to be used in a risk-based trading (RBT) scheme in England and Wales. To produce a practical scoring system the risk factors included need to be simple and quick to understand, sufficiently informative and derived from centralised national databases to enable verification and assess compliance. A logistic regression identified herd history of bTB, local bTB prevalence, herd size and movements of animals onto farms in batches from high risk areas as being significantly associated with the probability of bTB infection on farm. Risk factors were assigned points using the estimated odds ratios to weight them. The farm risk score was defined as the sum of these individual points yielding a range from 1 to 5 and was calculated for each cattle farm that was trading animals in England and Wales at the start of a year. Within 12 months, of those farms tested, 30.3% of score 5 farms had a breakdown (sensitivity). Of farms scoring 1-4 only 5.4% incurred a breakdown (1-specificity). The use of this risk scoring system within RBT has the potential to reduce infected cattle movements; however, there are cost implications in ensuring that the information underpinning any system is accurate and up to date.

  10. Prevalence of latent and active tuberculosis among dairy farm workers exposed to cattle infected by Mycobacterium bovis.

    Directory of Open Access Journals (Sweden)

    Pedro Torres-Gonzalez

    Full Text Available BACKGROUND: Human tuberculosis caused by M. bovis is a zoonosis presently considered sporadic in developed countries, but remains a poorly studied problem in low and middle resource countries. The disease in humans is mainly attributed to unpasteurized dairy products consumption. However, transmission due to exposure of humans to infected animals has been also recognized. The prevalence of tuberculosis infection and associated risk factors have been insufficiently characterized among dairy farm workers (DFW exposed in settings with poor control of bovine tuberculosis. METHODOLOGY/PRINCIPAL FINDINGS: Tuberculin skin test (TST and Interferon-gamma release assay (IGRA were administered to 311 dairy farm and abattoir workers and their household contacts linked to a dairy production and livestock facility in Mexico. Sputa of individuals with respiratory symptoms and samples from routine cattle necropsies were cultured for M. bovis and resulting spoligotypes were compared. The overall prevalence of latent tuberculosis infection (LTBI was 76.2% (95% CI, 71.4-80.9% by TST and 58.5% (95% CI, 53.0-64.0% by IGRA. Occupational exposure was associated to TST (OR 2.72; 95% CI, 1.31-5.64 and IGRA (OR 2.38; 95% CI, 1.31-4.30 adjusting for relevant variables. Two subjects were diagnosed with pulmonary tuberculosis, both caused by M. bovis. In one case, the spoligotype was identical to a strain isolated from bovines. CONCLUSIONS: We documented a high prevalence of latent and pulmonary TB among workers exposed to cattle infected with M. bovis, and increased risk among those occupationally exposed in non-ventilated spaces. Interspecies transmission is frequent and represents an occupational hazard in this setting.

  11. Farm to abattoir conditions, animal factors and their subsequent effects on cattle behavioural responses and beef quality — A review

    Directory of Open Access Journals (Sweden)

    Yonela Zifikile Njisane

    2017-06-01

    Full Text Available The current review seeks to highlight the concerns that have been raised on pre-slaughter stress, contributing factors and its consequent effects on cattle behavioural responses and the quality of beef; inter-linking the activities involved from birth to slaughter. Such information is crucial in light of the consumer concerns on overall animal welfare, quality of meat and food security. Slaughter animals are exposed to different conditions during production and transportation to abattoirs on a daily basis. However; the majority of studies that have been done previously singled out different environments in the meat production chain, while conclusions have been made that the welfare of slaughter animals and the quality of meat harvested from them is dependent on the whole chain. Behaviour is a critical component used to evaluate the animals’ wellbeing and it has been reported to have an effect on product quality. Apart from the influence of on-farm, transportation and abattoir conditions, the genetic background of the animal also affects how it perceives and responds to certain encounters. Stress activates the animals’ hypothalamic-pituitary-adrenal activity, triggering release of various stress hormones such as catecholamines and cortisol, thus glycogen depletion prior slaughter, elevated ultimate pH and poor muscle-meat conversion. Pre-slaughter stress sometimes results to cattle attaining bruises, resulting to the affected parts of the carcass being trimmed and condemned for human consumption, downgrading of the carcass and thus profit losses.

    Microclimatic temperatures provide better estimates of vector-borne disease transmission parameters than standard meteorological temperatures, as the microclimate represent the actual temperatures to which the vectors are exposed. The objectives of this study were to quantify farm-level geographic variations and temporal patterns in the extrinsic incubation period (EIP) of Schmallenberg virus transmitted by Culicoides in Denmark through generation of microclimatic temperatures surrounding all Danish cattle farms. We calculated the hourly microclimatic temperatures at potential vector-resting sites within a 500 m radius of 22,004 Danish cattle farms for the months April to November from 2000 to 2016. We then modeled the daily EIP of Schmallenberg virus at each farm, assuming vectors choose resting sites either randomly or based on temperatures (warmest or coolest available) every hour. The results of the model output are presented as 17-year averages. The difference between the warmest and coolest microhabitats at the same farm was on average 3.7 °C (5th and 95th percentiles: 1.0 °C to 7.8 °C). The mean EIP of Schmallenberg virus (5th and 95th percentiles) for all cattle farms during spring, summer, and autumn was: 23 (18-33), 14 (12-18) and 51 (48-55) days, respectively, assuming Culicoides select resting sites randomly. These estimated EIP values were considerably shorter than those estimated using standard meteorological temperatures obtained from a numerical weather prediction model for the same periods: 43 (39-52), 21 (17-24) and 57 (55-58) days, respectively. When assuming that vectors actively select the coolest resting sites at a farm, the EIP was 2.3 (range: 1.1 to 4.1) times longer compared to that of the warmest sites at the same farm. We estimated a wide range of EIP in different microclimatic habitats surrounding Danish cattle farms, stressing the importance of identifying the specific resting sites of vectors when modeling vector-borne disease

    The main objective of this study was to characterize spatial patterns of white-tailed deer (Odocoileus virginianus) movement related to bovine tuberculosis (bTB) transmission risk to cattle in north-western Minnesota. Twenty-one adult deer (16 females and 5 males) were captured during winter (January-March) 2011 in areas adjacent to where an outbreak (2005-2009) of bTB occurred in deer and cattle. Deer were fitted with GPS collars programmed to collect deer location information every 90 min over a 15-month period. The exact locations of cattle, cattle feeding areas, and stored forage that were available to collared deer were assessed seasonally. In total, 47% (n = 9) of collared deer survived to the end of the study. Causes of mortality included wolves (n = 6), hunters (n = 1) and unknown (n = 2); additionally, 2 deer were censored due to collar malfunctions. Our results indicated that 5 deer (25%) had home ranges that included 6 cattle farms (20%). Most (77%) of the deer visits occurred in areas where cattle were present, with most visits (60%) from 00:00 to 06:00. March to May revealed the most farm visitations by deer (37%). This study provided baseline information regarding cattle-deer interactions critical to transmission of bTB in this region and suggested that risk mitigation practices should be implemented to separate wildlife and domestic livestock when feasible. © 2016 Blackwell Verlag GmbH.

    The paper reports on the reproductive performance of smallholder dairy cross-bred cattle in Malaysia, as monitored by milk progesterone radioimmunoassay and rectal palpation. Infertility was identified as the major problem faced by the smallholder farmers. The results show that there is a strong and significant association between suckling and delayed post-partum ovarian activity. The longer calving intervals in smallholder dairy herds compared with those in institutional herds are due to inactive ovaries rather than failure to detect oestrus. The use of a progesterone releasing intravaginal device (PRID) for treatment of anoestrus resulted in 93% of cows cycling, with a conception rate of 46% to insemination at the induced oestrus. Cows that suckled their calves had significantly longer calving intervals. The mean body score for cattle on smallholder herds was 3.8 -+ 1.1, and fertile cows had significantly higher scores than infertile cows. There was strong evidence to suggest that increased body scores corresponded to shorter intervals between calving and resumption of sexual activity, calving and conception, and successive calvings.

    Microclimatic temperatures provide better estimates of vector-borne disease transmission parameters than standard meteorological temperatures, as the microclimate represent the actual temperatures to which the vectors are exposed. The objectives of this study were to quantify farm-level geographic......-resting sites within a 500 m radius of 22,004 Danish cattle farms for the months April to November from 2000 to 2016. We then modeled the daily EIP of Schmallenberg virus at each farm, assuming vectors choose resting sites either randomly or based on temperatures (warmest or coolest available) every hour....... The results of the model output are presented as 17-year averages. Results: The difference between the warmest and coolest microhabitats at the same farm was on average 3.7 °C (5th and 95th percentiles: 1.0 °C to 7.8 °C). The mean EIP of Schmallenberg virus (5th and 95th percentiles) for all cattle farms...

    Estonia is situated on the eastern coast of the Baltic Sea. This is a region with intensive cyclonic activity and therefore with a relatively high mean wind speed. Atmospheric circulation and its seasonal variation determine the general character of the Estonian wind regime over the Atlantic Ocean and Eurasia. However, the Baltic sea itself is a very important factor affecting wind climate, it has an especially strong influence on the wind regime in costal areas. The mean energy density (W/m 2 ) is a wind energy characteristic that is proportional to the third power of wind speed and describes energy available in a flow of air through a unit area. The mean energy density is a characteristic which has practical importance in regional assessment of snowdrift, storm damage and wind energy

    Identifying dairy cattle experiencing heat stress and adopting appropriate mitigation strategies can improve welfare and profitability. However, little is known about how cattle use heat abatement resources (shade, sprayed water) on drylot dairies. It is also unclear how often we need to observe animals to measure high heat load, or the relevance of specific aspects of this response, particularly in terms of panting. Our objectives were to describe and determine sampling intervals to measure cattle use of heat abatement resources, respiration rate (RR) and panting characteristics (drooling, open mouth, protruding tongue), and to evaluate the relationship between the latter 2. High-producing cows were chosen from 4 drylots (8 cows/dairy, n=32) and observed for at least 5.9h (1000 to 1800h, excluding milking) when air temperature, humidity, and the combined index averaged 33°C, 30%, and 79, respectively. Use of heat abatement resources was recorded continuously; RR and the presence and absence of each panting characteristic were recorded every 5min. From the observed values, estimates using the specified sub-sampling intervals were calculated for heat abatement resource use (1, 5, 10, 15, 20, 30, 60, 90, and 120min), and for RR and panting (10, 15, 20, 30, 60, 90, and 120min). Estimates and observed values were compared using linear regression. Sampling intervals were considered accurate if they met 3 criteria: R 2 ≥0.9, intercept=0, and slope=1. The relationship between RR and each panting characteristic was analyzed using mixed models. Cows used shade (at corral or over feed bunk) and feed bunk area (where water was sprayed) for about 90 and 50% of the observed time, respectively, and used areas with no cooling for 2min at a time, on average. Cows exhibited drooling (34±4% of observations) more often than open mouth and protruding tongue (11±3 and 8±3% of observations, respectively). Respiration rate varied depending on the presence of panting (with vs

    The problem of selenium and seleniferous soils and its effects on animal and human population are quite well known in Colombia since Colonial times. Its doesn't happen the same with Mo and molibdenosis, an element and disease which effects are so serious or worst than those of Se, which in this investigation we assume caused by the same cretaceous sediments (Villeta Group) which traditionally has been recognized only responsible of the formation of seleniferous soils and toxic vegetation. To prove the foregoing hypothesis and as a contribution to the knowledge of the origin and effects of Mo problem in Colombia, the soil and grasses of two cattle farms of Puerto Salgar (Cundinamarca, Colombia): La Gloria and Candilejas, both located in the border of two streams recognized as carriers of seleniferous sediments coming from Villeta Formation were analyzed. The water and sediments of three recognized seleniferous streams of the area were also analyzed. In all samples Se and Mo total content were determined. As a general conclusion Se and Mo content in soils and grasses in both cattle farms could induce variable degree of intoxication on animal and human population. In La Gloria's farm Se content in soil was 11 ppm in sites close to the river's border (0-60 mt) and decrease to 2.17 ppm in farthermost sites (268 mt). In Candilejas's farm Se decreases from 5.6 ppm in closer sites to the river's border (0-130 mt) to 2.63 ppm in farther sites (296 mt). In La Gloria's farm Mo decreases from an average of 3.40 to 4.55 ppm in the closer sites, to 1 ppm in those farther. In Candilejas's farm Mo decreases from 4.64 ppm in sites near the river's border to 0.15 ppm in farther sites. In both farms Se content in Angleton grass (Dichantum aristatum) samples was 0.8 ppm, Mo instead fluctuates around 9 ppm in those samples taken next to the river's border and decreases to an average of 3 ppm in samples taken farther from border. Average content of Se and Mo in all three stream

    Full Text Available The study aims to evaluate the Domestic Resources Cost (DRC of beef cattle raised either on grazing, or a tethering system of small-scale beef cattle farming. The study was done using a survey method. A total of 120 respondents were selected purposively to consist of 60 farmers applying the grazing system and another 60 farmers applying the tethering system. The parameters measured were socio-economic characteristic, Domestic Resources Cost Ratio (DRCR and Private Cost Ratio (PCR. Data were analyzed by applying a method of Policy Analysis Matrix (PAM. The result of the study indicated that 87% of those farmers involved in the grazing system and 85% of those involved in tethered beef cattle production, were within the productive age range. In the grazing system, the cattle farmers upstream of Benain-Noelmina watershed area gain the private and social profit levels which is IDR 406,284,-/AU/year and IDR 688,388,-/AU/year, respectively. Further, in the tethering system, the average of private and social profit gain is IDR 855,222,-/AU/year and IDR 1,385,712,-/AU/year, respectively. The small-scale beef cattle farming upstream of Benain-Noelmina watershed has competitive and comparative advantages, indicated by the value of PCR and DRCR which are less than 1. The PCR value was 0.41 in the grazing system and 0.71 on the tethering system; hence, the DRCR of the grazing system was 0.29 and 0.60 of the tethering system.

    Composting technologies and control systems have reached an advanced stage of development, but these are too complex and expensive for most agricultural practitioners for treating livestock slurries. The development of simple, but robust and cost-effective techniques for composting animal slurries is therefore required to realise the potential benefits of waste sanitation and soil improvement associated with composted livestock manures. Cattle slurry solid fraction (SF) was collected at the rates of 4m(3)h(-1) and 1m(3)h(-1) and composted in tall (1.7 m) and short (1.2m) static piles, to evaluate the physicochemical characteristics and nutrient dynamics of SF during composting without addition of bulking agent materials, and without turning or water addition. Highest maximum temperatures (62-64 °C) were measured in tall piles compared to short piles (52 °C). However, maximum rates of organic matter (OM) destruction were observed at mesophilic temperature ranges in short piles, compared to tall piles, whereas thermophilic temperatures in tall piles maximised sanitation and enhanced moisture reduction. Final OM losses were within the range of 520-660 g kg(-1) dry solids and the net loss of OM significantly (Pcomposting period. An advanced degree of stabilization of the SF was indicated by low final pile temperatures and C/N ratio, low concentrations of NH(4)(+) and increased concentrations of NO(3)(-) in SF composts. The results indicated that minimum intervention composting of SF in static piles over 168 days can produce agronomically effective organic soil amendments containing significant amounts of OM (772-856 g kg(-1)) and plant nutrients. The implications of a minimal intervention management approach to composting SF on compost pathogen reduction are discussed and possible measures to improve sanitation are suggested.

    Our objective was to evaluate how the proportion of high-producing lactating cows sampled on each farm and the selection method affect prevalence estimates for animal-based measures. We assessed the entire high-producing pen (days in milk size calculations from the Welfare Quality Protocol; and (4) selecting the first, middle, or final third of cows exiting the milking parlor. Estimates were compared with true values using regression analysis and were considered accurate if they met 3 criteria: the coefficient of determination was ≥0.9 and the slope and intercept did not differ significantly from 1 and 0, respectively. All estimates met the slope and intercept criteria, whereas the coefficient of determination increased when more cows were sampled. All estimates were accurate for neck alterations, ocular discharge (22.2 ± 27.4%), and carpal joint hair loss (14.1 ± 17.4%). Selecting a third of the milking order or using the Welfare Quality sample size calculations failed to accurately estimate all measures simultaneously. However, all estimates were accurate when selecting at least 2 of every 3 cows locked at the feed bunk. Using restraint position at the feed bunk did not differ systematically from computer-selecting the same proportion of cows randomly, and the former may be a simpler approach for welfare assessments.

    Mycobacterium avium ssp. paratuberculosis (MAP), the causative agent of Johne's disease, is present on most dairy farms in Alberta, causing economic losses and presenting a potential public health concern. The objective of this cross-sectional study was to identify risk factors for Alberta dairy herds being MAP-positive based on environmental samples (ES). Risk assessments were conducted and ES were collected on 354 Alberta dairy farms (62% of eligible producers) voluntarily participating in the Alberta Johne's Disease Initiative. In univariate logistic regression, risk factors addressing animal and pen hygiene, as well as the use of feeding equipment to remove manure and manure application on pastures, were all associated with the number of positive ES. Furthermore, based on factor analysis, risk factors were clustered and could be summarized as 4 independent factors: (1) animal, pen, and feeder contamination; (2) shared equipment and pasture contamination; (3) calf diet; and (4) cattle purchase. Using these factor scores as independent variables in multivariate logistic regression models, a 1-unit increase in animal, pen, and feeder contamination resulted in 1.31 times higher odds of having at least 1 positive ES. Furthermore, a 1-unit increase in cattle purchase also resulted in 1.31 times the odds of having at least 1 positive ES. Finally, a 100-cow increase in herd size resulted in an odds ratio of 2.1 for having at least 1 positive ES. In conclusion, cleanliness of animals, pens, and feeders, as well as cattle purchase practices, affected risk of herd infection with MAP. Therefore, improvements in those management practices should be the focus of effective tools to control MAP on dairy farms. Copyright © 2016 American Dairy Science Association.

    Energy policy, environmental protection and economy form a triangle of tightly linked sectors, and any solution of some energy problem can be solved only in the light of all the above mentioned factors. There are several energy master plans for Estonia, the first of them dating back to the years of the Soviet Union and ending the list with the plan to cover the years up to 2000. By now the basic principles of the Estonian energy policy have been prepared and Estonian Energy Concept is being worked out. The main goal of Estonian energy policy is ensure an effective and environmentally benign energy supply for the country. It means safety in energy supply, effective production and supply together with sufficient environmental protection. Energy Council in the role of an advisory voluntary organization for inspection of the energy system and finding measures to improve its efficiency is established with parliament members included. The Estonian Energy Research Institute and the Oil--Shale Research Institute serve as a scientific advisory board for the government in energy policy. It's important to emphasise that privatisation is no panacea, solving all the problems, and therefore we are facing hard to move in the right direction, satisfying all the consumers of energy

    Full Text Available The article describes logistics survey in Estonia carried out in 2007 as a part of the LogOnBaltic project. The level of logistics in Estonian manufacturing, trading and logistics companies is explored through logistics costs, performance indicators, outsourcing, ICT use and logistics self-estimation of the companies responded. Responses from 186 Estonian companies were gathered through a web-based survey (38% of manufacturing, 38% of trading and 24% of logistics sector. Logistics costs as the percentage of turnover make in average 13.8% in manufacturing and 13.3% in trading. Transportation and inventory carrying cost form around 70% of overall logistics costs. Considering the logistics indicators surveyed, Estonian companies show up with relatively low perfect order fulfillment rates, short customer order fulfillment cycles and effective management of cash flows. The most widely outsourced logistics function is international transportation followed by domestic transportation, freight forwarding and reverse logistics. By 2010, the outsourcing of IT systems in logistics followed by inventory management, warehousing and product customization is expected to increase more substantially. The awareness of logistics importance is still low among Estonian companies. Only 27–44% of those agree that logistics has a considerable impact on profitability, competitive advantage, top management or customer service level.

    The aim of this study was to determine sero-prevalence of bovine and porcine cysticercosis in cattle and pigs in rural farming communities in Free State and Gauteng Provinces, Republic of South Africa. Blood samples were collected for a period of twelve months from live cattle (n=1315; 1159) and pigs (n=436; 240) and the serum extracted and stored before analysis by a monoclonal antibody based (HP10) antigen detection ELISA. Results revealed a generally high sero-prevalence and wide distribution throughout the two provinces with Free State having a higher sero-prevalence in both cattle and pigs (23% and 34%) than Gauteng province (15% and 14%). Consumption of infected meat that is either not inspected/missed at meat inspection; poor livestock management practices and limited sanitation in rural communities might have contributed to the occurrence of Taenia spp. infections in the two provinces. It is therefore, recommended that cysticercosis status of animals be established before slaughter. This would assist in ensuring that infected animals are not slaughtered for human consumption or zoonosis preventive measures are taken. Furthermore, public awareness programs on life cycles of T. saginata, T. solium and T. hydatigena and the use of more sensitive diagnostic tools are recommended as part of effective control strategies against taeniid infections.

    Full Text Available People’s awareness on the living environment nowadays is not yet comes up to the dairy-farmer community. In fact, the dairy-farm subsector contributes load pollution in the form of waste. The waste that is produced by a dairy-farm can be in the form of solid waste and liquid waste. There is still no cultivation effort toward the wastes in a traditional dairy-farmyet, thus most of the wastes are disposed to the closest river, so that in the surrounding dairy farm area is frequently found pollution toward the water quality. The aim of this study is to identify the effect of environment pollution that is caused by local dairy farm in Gunungpati Sub-district, especially toward the river water and residents’ well. The result of this study in Nangkasawit Village before and after the dairy farm was build was still under the quality standard for the third rate water quality. In Plalangan Village, the water quality was also under the quality standard, except for COD concentration. In the Sumurejo Village there was an upturn tendency on the observation value, but the water quality was under the quality standard, except for Fe concentration. Based on the Biodiversity Index before and after the dairy farm was established in Nangkasawit, Plalangan, and Sumurejo were 2.22, 1.49, 2.11, 1.90, 1.78, and 1.88, respectively. It means that Nangkasawit showed no pollution before the dairy farm was established, while there was a medium pollution after the dairy farm establishment.  In Plalangan, the water was clear, but it was light polluted after the dairy farm was established. In Sumurejo, before and after the dairy farm establishment the water was light category pollution.

    Prehistoric and early historic human cultures are known to be closely connected to and dependent on their natural environments. We test the hypothesis that climate change influenced the means of subsistence of ancient tribes and favored agricultural or cattle herding economic strategies. Our study area is the Khakass–Minusinsk Hollow, located in the foothills of the Sayan Mountains, south-central Siberia, which was, for a few millennia, a buffer zone for human migrations across the Great Eurasian Steppe. Three different methods (the Montane BioClimatic Model, MontBCliM; the biomization method; and the actualizm method) are employed to reconstruct vegetation taken from the fossil pollen of sediment cores in two mountain lakes at eleven time slices related to successive human cultures back to the mid-Holocene. MontBCliM model is used inversely to convert site paleo-vegetation into site paleo-climates. Climate-based regression models are developed and applied to reconstructed climates to evaluate possible pasture and grain crops for these time slices. Pollen-based reconstructions of the climate fluctuations uncovered several dry periods with steppe and forest-steppe and wetter periods with forests since 6000 BP. Grasslands increased by an order of magnitude during the dry periods and provided extensive open space suitable for pastoralism; however, both grain and pasture yields decreased during these dry periods. During wetter climates, both grain and pasture yields increased twofold and supported more fixed human settlements centered around farming and cattle herding. Thus, the dry periods favored pastoralist rather than farming activities. Conversely, tribes that practiced agriculture had some advantage in the wet periods. (papers)

    Mycobacterium avium subsp. paratuberculosis (MAP) is an etiological agent of Johne's disease in ruminant including cattle, sheep and goats. This disease is considered an economically important disease in cattle. Animals with paratuberculosis shed viable MAP, particularly in their milk and feces. MAP may be involved in the development of Crohn's disease in humans through the consumption of contaminated milk and dairy products. Common methods of pasteurization are not enough to kill all MAP present in the milk and the bacterium has been isolated from raw milk, pasteurized milk and cheese samples. The purpose of this study was to evaluate two different methods for detecting MAP in milk and milk products. We analyzed the commonly used methods such as culture and molecular biology for identification of MAP. For this study, 50 milk samples from cows with suspected Johne's disease located in two dairy farms and 10 commercially available pasteurized milk and cheese samples from the market in Karaj city, Iran were selected. Following Ziehl-Neelsen staining of milk samples, direct microscopic detection of MAP was performed. All milk samples were centrifuged, and the concentrated samples were decontaminated using hexadecyl pyridinium chloride. The decontaminated milk suspensions were washed three times by centrifuging, and the collected filtrates were cultivated on Herrold's egg yolk medium enriched by Mycobactin J. Finally, identification and confirmation of isolates to MAP was performed using IS900-nested polymerase chain reaction (PCR). According to the obtained results by culture and PCR methods, none of the pasteurized milk and cheese samples showed the presence of MAP. However, 10% of the tested raw milk samples collected from suspected cattle showed the presence of MAP by both culture and PCR methods. Culture and PCR methods are reliable for identification of MAP from milk samples. Copyright © 2016.

    Identifying sources of Mycobacterium bovis transmission would be essential for establishing effective control programs of bovine tuberculosis (TB), a major zoonosis threatening human health worldwide. As an effort to determine the extent of M. bovis transmission among dairy and beef cattle and deer populations, a mycobacterial interspersed repetitive units (MIRU)-variable-number tandem repeats (VNTR) typing method was employed for analysis of 131 M. bovis isolates from 59 Holstein dairy cattle, 39 Korean beef cattle, and 33 deer. Of 31 MIRU-VNTR markers, 15 showed allelic diversity. The most discriminatory locus for M. bovis isolates was VNTR 3336 (h=0.59) followed by QUB 26, MIRU 31, VNTR 2401, and VNTR 3171 which showed high discriminatory power (h=0.43). The combined VNTR loci had an allelic diversity of 0.83. On the basis of the VNTR profiles of 30 VNTR loci, 24 genotypes were identified, and two genotypes were highly prevalent among all M. bovis isolates (33.6% and 19.1%, respectively), thus indicating that more than 50% of the isolates shared common molecular characteristics. Six additional genotypes were common in 2 of the 3 animal species, suggesting a wide interspecies transmission of M. bovis. This study thus demonstrates that MIRU-VNTR typing is useful in differentiation of M. bovis isolates and that M. bovis transmission occurs frequently among farmed animal species, highlighting the importance of bovine TB control programs in different animal species which are often raised in the same villages.

    Biochar has positive effects on nitrogen conservation during anaerobic digestion, but its impacts on antibiotic resistance genes (ARGs) are unclear. Therefore, the effect of biochar (0, 5, 20, and 50 g/L) on the environmental risk of ARGs during cattle manure wastewater anaerobic digestion were investigated. The results showed that 5 g/L biochar reduced the relative abundances (RAs) of 5/13 ARGs while 20 g/L biochar significantly reduced the total RAs of ARGs in the digestion products, where the RA of ISCR1 was 0.89 log lower than the control. Biochar mainly affected the distribution of ARGs by influencing the RAs of Firmicutes and Proteobacteria, and the influence of 20 g/L biochar was greater than that of 5 g/L. Mobile genetic elements also influenced the ARG profiles, especially intI2 and ISCR1. The addition of 20 g/L biochar to cattle farm wastewater anaerobic digestion systems could reduce the environmental risk of ARGs. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available The perception of risks due to climate change by farmers and the measures they take to address those risks are of paramount importance in policy-making if the implementations of targeted adaptation and mitigation strategies are to be economically and environmentally sustainable. This study focused on Tunisian dairy farmers’ perceptions of the risks and the actions taken to cope with changes attributable to climate change. Using a bottom-up approach, 566 surveys were carried out randomly among dairy farmers throughout Tunisia. A total of 70 diagnostic variables relating to farm characteristics, resources, management, performances and profit, in addition to climate change risk perception and adaptation strategies, were identified and analyzed. Using multivariate statistical analysis, four dairy farming groups were identified. The largest proportions of farmers belonged to the two above-ground dairy systems: without utilized agricultural areas; and with non-dairy utilized agricultural areas (Clusters 1 and 2. A minority of farmers belonged to medium-sized and large farms that specialized in milk production (Clusters 3 and 4 and has access to sufficient land, water and capital resources. In all the clusters, almost all the farmers perceived that the greatest impact of climate change would be on cow performance and forage production. The attitudes of the farmers towards adaptation to climate change are associated with farm typology. They focused mainly on increasing water capacity for livestock and crop production and improving livestock and housing conditions. The knowledge obtained from this study could be helpful for decision-makers and stakeholders in efforts to develop policies for farm management practices that address climate change and can be adapted to the country’s diverse farming systems.

    The objective was to conduct a survey of current fresh cow management practices that have an effect on health and diseases postpartum considering different herd sizes of commercial dairy farms. A mail survey regarding aspects of the fresh cow program including general management issues, calving, diseases, and veterinary service was conducted utilizing a convenience sample. A total of 429 survey forms were returned (12.0% response rate) and could be used for final analysis. Only 21.6% of the farms had a designated fresh cow pen. Almost every farm executed some type of fresh cow examination. Only 18.5% of farm managers documented the observations. Most of the dairy managers used more or less subjective criteria such as general appearance (97.0%) and appetite (69.7%). Only a minority of the responding dairy managers monitored their fresh cows using objective (fever 33.6%) or semiquantitative measures (subclinical ketosis 2.8%; body condition score 36.4%). On most farms, the veterinarian visited the herd only if needed (72.6%). Most cases of retained fetal membranes were treated by manual removal (72.3%) and antibiotic pills (89.5%). Several challenges and opportunities were identified to improve cow management practices.

    Our objectives were to establish a methodology for surveillance of ciprofloxacin-resistant Enterobacteriaceae and gentamicin-resistant Enterobacteriaceae (CPRE and GNRE, respectively) in cattle and to study the prevalence and risk factors for carriage of these bacteria in a national survey. This was a point prevalence study conducted from July to October 2013 in Israel. Stool samples were collected from 1,226 cows in 123 sections of 40 farms of all production types. The number of CPRE- and GNRE-positive cows was highest in quarantine stations and fattening farms and was lowest in pasture farms (p 25 months) and highest in calves (<4 months) (p < 0.001). In bivariate analysis, other variables that were significant risk factors for CPRE and GNRE carriage included fewer troughs, crowding, lack of manure cleaning, and recent arrival of new calves. Antimicrobial prophylaxis was given almost exclusively to calves and was associated with a higher prevalence of carriers (p < 0.001). Compared to the use of nonselective media (MacConkey agar alone), the use of selective media (MacConkey agar with 10 μg/ml of ciprofloxacin or 5 μg/ml of gentamicin) increased the sensitivity of screening for CPRE and GNRE by 6.6- and 13.5-fold, respectively. CPRE and GNRE were identified in 609 (49.7%) and 840 (68.5%) samples, respectively. This study provides novel data regarding both the epidemiology of CPRE and GNRE carriage in livestock and the microbiological methodology for their surveillance.

    Full Text Available Intensification of milk production occurs even in areas traditionally characterized by low-intensive farming systems like mountain areas, leading to environmental concern. The aim of this study was to analyze management and feeding systems in a sample of 31 dairy farms in a mountain area of Lombardy (Valtellina and their effects on milk production and environmental sustainability. In 2006 daily milk sold was 17.5±5.6 kg/cow on average and daily DMI was 19.4±1.3 kg/cow, with a high forages content (65.8±9.2% DM. Rations were quite energetically balanced (+0.09±17.6 MJ/d of ME. Rations higher in starch and lower in NDF resulted in higher milk yields but significantly compromised farm self-sufficiency (which was 62.9±16.8% DM on average. Average Metabolizable Protein balance was negative (-280±203 g/d of MP, mainly due to the low CP content of diets (13.5±1.5% DM. When CP content increased, N manure and N excreted in urine increased (P<0.05 and P<0.01 respectively, probably due to insufficient energy intake which is partly caused by the scarce quality of forages. An improvement in forages quality could increase ME and MP contents of diets without compromising farm self-sufficiency.

    This study evaluated effects of farming practice scenarios aiming to reduce greenhouse gas (GHG) emissions and subsequent alternative land use on environmental impacts of a beef cattle production system using the life cycle assessment approach. The baseline scenario includes a standard cow-calf herd with finishing heifers based on grazing, and a standard bull-fattening herd using a diet mainly based on maize silage, corresponding to current farm characteristics and management by beef farmers in France. Alternative scenarios were developed with changes in farming practices. Some scenarios modified grassland management (S1: decreasing mineral N fertiliser on permanent grassland; S2: decreasing grass losses during grazing) or herd management (S3: underfeeding of heifers in winter; S4: fattening female calves instead of being reared at a moderate growth rate; S5: increasing longevity of cows from 7 to 9 years; S6: advancing first calving age from 3 to 2 years). Other scenarios replaced protein sources (S7: partially replacing a protein supplement by lucerne hay for the cow-calf herd; S8: replacing soya bean meal with rapeseed meal for the fattening herd) or increased n-3 fatty acid content using extruded linseed (S9). The combination of compatible scenarios S1, S2, S5, S6 and S8 was also studied (S10). The impacts, such as climate change (CC, not including CO2 emissions/sequestration of land use and land-use change, LULUC), CC/LULUC (including CO2 emissions of LULUC), cumulative energy demand, eutrophication (EP), acidification and land occupation (LO) were expressed per kg of carcass mass and per ha of land occupied. Compared with the baseline, the most promising practice to reduce impacts per kg carcass mass was S10 (all reduced by 13% to 28%), followed by S6 (by 8% to 10%). For other scenarios, impact reduction did not exceed 5%, except for EP (up to 11%) and LO (up to 10%). Effects of changes in farming practices (the scenarios) on environmental impacts varied

    Several multiple-media culture systems have become commercially available for on-farm identification of mastitis-associated pathogens. However, the accuracy of these systems has not been thoroughly and independently validated against microbiological evaluations performed by referral laboratories. Therefore, the purpose of the present study was to evaluate the performance of commercially available culture plates (Accumast, Minnesota Easy System, SSGN and SSGNC Quad plates) to identify pathogens associated with clinical mastitis in dairy cows. Milk samples from the affected quarter with clinical mastitis were aerobically cultured with the on-farm culture systems and by two additional reference laboratories. Agreeing results from both standard laboratories were denoted as the reference standard (RS). Accuracy (Ac), sensitivity (Se), specificity (Sp), positive and negative predictive values (PPV and NPV, respectively) and Cohen's kappa coefficient (k) of on-farm plates were determined based on the RS culture of 211 milk samples. All four plate-systems correctly identified ≥ 84.9% of milk samples with no bacterial growth. Accumast had greater values for all overall predictive factors (Ac, Se, Sp, PPV and NPV) and a substantial agreement (k = 0.79) with RS. The inter-rater agreements of Minnesota, SSGN, and SSGNC with RS were moderate (0.45 ≤ k ≤ 0.55). The effectiveness to categorize bacterial colonies at the genus and species was numerically different amongst the commercial plates. Our findings suggest that Accumast was the most accurate on-farm culture system for identification of mastitis-associated pathogens of the four systems included in the analysis.

The purpose of this study was to formulate stakeholders relation in the future program. The stakeholders involved in this program were PT KPC, local breeders, Sekolah Tinggi Ilmu Pertanian (STIPER; Agriculture Academy of East Kutai, and the local government of East Kutai. The stakeholders analysis was based on the variables of the importance and influence from every analyzed stakeholder. The analysis model used here was the model introduced by Reed et al. (2009. According to the result of the stakeholders analysis, PT KPC was in the key-player quadrant, which score is 25 in both of the interest and the influencial level, while the three others, such as, local breeders, STIPER of East Kutai, and the East Kutai Government were in the subject quadrant. Their score were 24 and 7 for Local breeders, 21 and 9 for STIPER of East Kutai, and 16 and 13 for The East Kutai Government. It means, they had high interest but low influence to the program. The conclusion of this analysis shows that PT KPC is still dominating in the PESAT program management, whereas the three other stakeholders are acting merely as program users that have low involvement in the program management.

    Full Text Available Despite the importance of human taeniasis/bovine cysticercosis for public and animal health and the economy, its actual epidemiological status in Brazil is not well-studied. We sought to assess the epidemiological profile of this zoonosis in the rural area of Viçosa County, Minas Gerais, Brazil. The prevalence of bovine cysticercosis was 0.42%, whereas no case of human taeniasis was diagnosed. Factors favoring the persistence of zoonosis were identified. These included the supply of untreated water to animals, animals raised for slaughter without sanitary supervision, poor mechanization of raising techniques, and the use of untreated water for human consumption. Bovine meat for human consumption acquired in the city or from the farm itself was characterized as a risk factor for bovine cysticercosis (Odds Ratio (OR =16.77; p<0.05. Nevertheless, the families on the investigated farms did apply several appropriate measures to control this disease, such as the virtual lack of open sewers and the consumption of well-cooked meat. The presence of bovine cysticercosis cases, and the factors favoring its persistence, point to the need for constant epidemiological and sanitary surveillance in this county.

    The objective of this study was to compare calving traits, BCS, milk production, fertility, and survival of Holstein-Friesian (HF) and Norwegian Red (NR) dairy cattle in moderate-concentrate input systems. The experiment was conducted on 19 commercial Northern Ireland dairy farms, and involved 221 HF cows and 221 NR cows. Cows completed 5 lactations during the experiment, unless they died or were culled or sold. Norwegian Red cows had a lower calving difficulty score than HF cows when calving for the first and second time, but not for the third and fourth time. At first calving, the incidence of stillbirths for NR cows was 4%, compared with 13% for HF cows, whereas no difference existed between breeds in the proportion of calves born alive when calving for the second time. When calving for the first time, NR cows had a poorer milking temperament than HF cows, whereas milking temperament was unaffected by breed following the second calving. Holstein-Friesian cows had a higher full-lactation milk yield than NR cows, whereas NR cows produced milk with a higher milk fat and protein content. Full-lactation fat + protein yield was unaffected by genotype. Norwegian Red cows had a lower somatic cell score than HF cows during all lactations. Although NR cattle had a higher BCS than the HF cows during lactations 1 and 2, no evidence existed that the 2 genotypes either lost or gained body condition at different rates. Conception rates to first artificial insemination were higher with the NR cows during lactations 1 to 4 (57.8 vs. 40.9%, respectively), with 28.5% of HF cows and 11.8% of NR cows culled as infertile before lactation 6. A greater percentage of NR cows calved for a sixth time compared with HF cows (27.2 vs. 16.3%, respectively). In general, NR cows outperformed HF cows in traits that have been historically included in the NR breeding program. Copyright © 2014 American Dairy Science Association. Published by Elsevier Inc.

    Full Text Available The article examines the cultural situation following postmodernism in the first decade of the 21st century. To characterise this situation, the umbrella term “post-postmodernism” is used, as well as “neomodernism”, “altermodern”, “metamodernism”, “hypermodernity”, “performatism”, “critical realism” etc. All these approaches are, in a wider sense, united by their aim of opposing postmodernist cynicism and irony, and bringing back truth, simplicity and clarity. It has also been found that literature has returned or is returning to realism, and various cultural phenomena are emerging, which have been designated by the concept “new sincerity”.In descriptions of the current cultural situation, this trend seeking truth and simplicity is supported by approaches which emphasise the significance of technological developments during the last decade. A prominent figure here is Alan Kirby, who launched the term “digimodernism”, mainly linked with the adaptation and spread of Web 2.0 at the beginning of the 21st century: the blogosphere, Wikipedia, Twitter and Facebook.The article seeks answers to the question of whether we can talk about digimodernism in Estonian literature in the 2000s. In the 1990s Estonian writers were quite reluctant to undertake computer-technological experiments, and there are only a few examples of Estonian digital literature, whereas a change occurred in the 2000s. Many Estonian writers have had and still have their own blogs and surprisingly many have joined Facebook. The term “twitterature” is also familiar to Estonian writers. The article tackles the dominant topics in the blogs of Estonian writers and analyses their possible collective creative work on Facebook. A question is raised as to whether it is possible that the fragmentary narrative structure of blogs and Facebook has influenced mainstream literature.The article concludes that one essential change in Estonian literature in the

    A study was carried out in the Mzuzu milk shed area in Northern Malawi, to identify major constraints to dairy cattle production systems prevailing in the area (Phase I) and develop a sustainable feed supplementation intervention (Phase II) based on tree legume leaves of Sesbania sesban for increasing milk production. Phase I of the study revealed that the major constraint to increasing productivity was poor nutrition related to the fluctuating supply of quality and quantity of feed. Body weights of cows averaged 301 ± 81.3 kg and ranged from 189 to 550 kg whereas the body condition score (BCS, on 1-9 scale) averaged 5.73 ± 1.35 and ranged from 2.00 to 9.00. Average milk production was 6.1 ± 5 kg/d and ranged from 1.5 to 19.0 kg/d. Post-partum reproductive status varied considerably. Cows consumed 10.6 ± 6.2 kg/day of roughage and 2.96 ± 1.45 kg/day of concentrates. The quality of the feeds was moderate. Roughages contained 1.56 ± 0.12% N while concentrates contained 1.88 ± 0.04% N. Poor reproductive management and prevalence of internal parasites were also identified as constraints. The intervention (Phase II) based on supplementation with tree legume leaves of Sesbania sesban significantly (P <0.05) improved the performance of dairy cows. Cows supplemented with tree legume leaves showed significantly higher body weights (368 ± 65.5 vs 348.7 ± 59.2 kg) and BCS (6.3 ± 0.9 vs 5.3 ± 1) compared to their counterparts receiving a supplement according to the present management practice. Daily milk yields of cows on the experimental diet averaged 8.6 ± 3.2 kg whereas those on control diet averaged 5.4 ± 1.7 kg. Significant differences in milk yields between the two groups of cows could have been due to higher dry matter intake from the supplementary diet. Cows on experimental diet consumed 3.5 ± 1.2 kg of supplementary feed as compared to 2.2 ± 0.7 kg by cows on the control diet. (author)

  6. Summary of the co-ordinated research project on development of feed supplementation strategies for improving the productivity of dairy cattle on smallholder farms in Africa

    Livestock are an important and integral part of most farming systems in Africa. Recent nutritional research has demonstrated the possibility of substantial increases in the productivity of milk-producing animals fed poor quality roughages through small alterations to the feed base. In some cases, improvements have been demonstrated at the farm level: milk yield has increased, body condition of the animals has improved and age at puberty and the interval between calvings have been reduced. These advances have been brought about by the addition of critical nutrients to the diet, e.g. nitrogen or minerals for the rumen micro-organisms or rumen non-degradable protein or all of these. The introduction of improved feeding practices such as strategic supplementation using locally available feed resources (e.g. tree legume leaves, brewers waste, fish waste, multinutrient blocks, etc.) will not only enhance milk production but will also introduce a sustainable fanning practice that will ensure a continuous supply of milk and milk products to local populations. To introduce effective supplementation there is a need to identify the nutrient or combination of nutrients that are the limiting factors for achieving optimum rumen fermentative digestion of the basal diet or the efficiency of utilization of the major products of digestion. In many of the dairying systems operating in Africa this is far from easy, mainly because of the difficulties encountered in effectively measuring feed intake and selection and the efficiency with which the nutrients absorbed are used for productive purposes. In order to circumvent these difficulties it may be possible to measure biochemical indicators in the cows themselves that provide an assessment of nutrient status. The specific objectives of the co-ordinated research project (CRP) were to: - btain baseline information on production and reproductive parameters using a comprehensive survey, progesterone radioimmunoassay and clinical

    Full Text Available Introduction:Escherichia coli is a common bacterium in the intestinal microflora of warm-blooded animals. They are routinely shed into the environment through feces and can contaminate water and soil, and, consequently fruits and vegetables .Enterohemorrhagic E. coli strains are recently emerged group of food-borne pathogens that are a significant public health threat. This group causes bloody diarrhea and hemolytic uremic syndrome (HUS, and the disease is prevalent in developed countries. The purpose of this study was to isolate and identify the E.coli O157: H7 and other verotoxigenic ones and major virulence genes (rfbE, eaeA, stx1, stx2 in fecal swab samples by PCR in Shahrekord area. Materials and methods: In Spring and Summer 2015, 400 cow fecal swab samples were collected from farms in Shahrekord area. Bacteriological and biochemical examinations were done for detection of E.coli. PCR assay was done for identification of O157:H7 serotype and other verotoxigenic E. coli using rfbE, eae, stx1 and stx2 genes. Results: E. coli O157:H7 was not detected in any strains tested. But PCR showed that out of 384 E.coli strain, 104(27/08% isolates carried stx1 gene, 36(9/37% carried stx2 gene and 16 (4.16% carried both stx1 and stx2 genes. Intimin (eaeA gene was detected in 280(72/91% of the isolates. Among verotoxigenic strain antibiotic resistance to Tetracycline 87/1%, Ampiciline 51/62%, Cefotaxime 48/38%, Gentamycin 25/81%,, Ciprofeloxacin 3/22% and Sulfamethoxazol 3/22% were observed. Discussion and conclusion: According to the results, although the serotype O157: H7 did not isolate from the feces of cattle but other verotoxigenic strains that showed high resistance  to antibiotic were isolated so it is a risk for human health.

    This study investigated 247 Escherichia coli isolates collected from four cattle farms to characterize aminoglycoside-modifying enzyme (AME) genes, their plasmid replicons and transferability. Out of 247 isolates a high number of isolates (total 202; 81.78%) were found to be resistant to various antibiotics by disc diffusion. Of the 247 strains, 139 (56.3%) were resistant to streptomycin, and other antibiotic resistances followed as tetracycline (12.15%), ampicillin (7%), chloramphenicol (5.7%) and trimethoprim-sulfamethoxazole (0.8%). Among 247 isolates B1 was the predominant phylogenetic group identified comprising 151 isolates (61.1%), followed by groups A (27.9%), D (7%) and B2 (4%). Out of 139 isolates investigated for AME, 130 (93.5%) isolates carried at least one AME gene. aph3″-1a and aph3″-1b (46%) were the principal genes detected, followed by aac3-IVa (34.5%). ant2″-1a was the least detected gene (2.2%). Nine (6.5%) strains carried no AME genes. Twelve (63.2%) among 19 isolates transferred an AME gene to a recipient and aph3΄-1a was the dominant transferred gene. Transferability mainly occurred via the IncFIB replicon type (52.6%). Pulsed-field gel electrophoresis typing demonstrated a higher degree of diversity with 14 distinct cluster types. This result suggests that commensal microflora from food-producing animals has a tremendous ability to harbor and transfer AME genes, and poses a potential risk by dissemination of resistance to humans through the food chain. © FEMS 2017.

    Full Text Available Purpose – The study is a contribution to the validation of the 15 items and 5 subscales Transformational Leadership Scale (TLS proposed by Rafferty and Griffin (2004. Design/methodology/approach – The sample includes participants from different levels of the Estonian Defence Forces (EDF military hierarchy (N=2570. The structure of the TLS was examined by using exploratory and confirmatory factor analyses. Additionally ANOVA was used to compare the results between different subsamples. Findings – TLS showed satisfactory reliability. Confirmatory factor analyses found TLS as valid five dimensions instrument to measure transformational leadership in the Estonian military context. Different management levels showed different emphases among the dimensions of transformational leadership. Research and practical limitations/implications – TLS will be an important tool to use in transformational leadership research in the Estonian military context and beyond. Additionally, the current research contributes to the development of alternative measurement tools besides the most commonly used MLQ. The limitation of the work will be the rather homogenous sample from the Estonian military, however it will open the door for the subsequent research using different samplings. Originality/value – The current research found TLS to be a reliable and valid instrument, very short and therefore easy to administrate, having the possibility to use it with five dimensional and as one general transformational instrument as well.

    The Organization of Estonian energetic economy is aimed at cutting the usage of oil, gas and coal and increasing the local resources firewood, oil-shale and peat for fuel. The resources of low-valued firewood-brushwood, fallen deadwood etc. are available during the following 10-15 years, but in the future the cultivation of energy forest (willow) plantations will be actual. During the last 20 years the Swedish scientists have been extensively studying the willow forest selection, cultivation and use in energetics and waste water purification systems. A Swedish-Estonian energy forest research project was started in 1993 between the Swedish Agricultural University on one hand and Toravere Observatory, Institute of Zoology and Botany, Estonian Academy of Sciences and Estonian Potato Processing Association on the other hand. In spring 5 willow plantations were established with the help of Swedish colleagues and obtained from Sweden 36000 willow cuttings. The aim of the project: a) To study experimentally and by means of mathematical modelling the biogeophysical aspects of growth and productivity of willow plantations in Sweden and Estonian climatological conditions. b) To study the possibility of using the willow plantations in waste waters purification. c) To study the economical efficiency of energy forest as an energy resource under the economic and environmental conditions of Estonia. d) To study the economic efficiency of willow plantations as a raw material for the basket industry in Estonia. e) To select the most productive and least vulnerable willow clones for practical application in energy plantations. During 1993 in all five plantations detailed analysis of soil properties has been carried out. In the plantation at Toravere Observatory phytometrical measurements were carried out - the growth of plant biomass leaf and stem area, vertical distribution of dry matter content, biomass and phyto area separately for leaves and stems has been performed.

    Flue gas emissions from pulverized oil shale fired boilers of Estonian and Baltic power plants have been studied. The concentrations of NO x , CO, C x H y , HCI, Hf and polycyclic aromatic hydrocarbons in flue gases have been found to be relatively low and acceptable according to German emission limits, for instance. Desulphurization degree of flue gases by SO 2 absorption with ash has been found to vary defending on boiler type and operation conditions. In spite of significant sulphur capture (average values for different boilers in the range between 68 and 77 % of the initial sulphur content of the fuel), SO 2 concentrations in flue gases remain still very high (up to 2600 mg/m 3 , 10% O 2 ). Very high concentrations of particles, especially at Estonian Power Plant (up o 6250 mg/m 3 , 10 % 0 2 ) have been detected. Heavy metal emissions were too high by the reason of particle control insufficiency as well. Yearly emission estimates of this study support the former Estonian ones within the range of 10-15 %.

    The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture through co-ordinated research projects (CRP) supports studies aimed at improving livestock productivity in developing countries through the application of nuclear and related techniques. These studies have focused on animal nutrition, animal reproduction and more recently on animal nutrition/reproduction interactions with emphasis on smallholder farming systems. The primary aim of this CRP was to identify approaches for improving the productivity of dairy cattle maintained on smallholder farms in peri-urban areas. Central to the approach was to first obtain baseline information on productivity and reproductive efficiency and thereby identify nutritional and management constraints. Subsequently, corrective measures were developed and tested, keeping in mind the need for maximising the efficiency of current production systems and sustaining the nutrient supply through practical and economically feasible feed supplementation strategies developed using locally available feed resources. In addition the project envisaged contributing to enhancing the level of expertise within the national animal production research institutes in the region, to encourage close contact and interaction between scientists and institutions in Africa and to promote scientific information exchange on a regional basis. Through the project substantial progress was made in understanding the relationship between nutrient supply and productive and reproductive functions in dairy cattle on smallholder farming systems. Most of the participating countries were able to develop and test cost-effective feed supplementation strategies which improved both milk production and/or reproductive efficiency.

    Calf disease may result in great economic losses. To implement prevention strategies it is important to gain information on management and to point out risk factors. The objective of this internet based survey was to describe calf management practices on registered dairy breeding farms in Austria and to estimate differences in calf disease incidences depending on farm structure and management practices. A total of 1287 questionnaires were finally analysed (response rate 12.2 %). Herd characteristics and regional distribution of farms indicated that this survey gives a good overview on calf management practices on registered dairy farms in Austria. The median number of cows per farm was 20 (interquartile range 13-30). Significant differences regarding farm characteristics and calf management between small and large farms (≤20 vs >20 cows) were present. Only 2.8 % of farmers tested first colostrum quality by use of a hydrometer. Storing frozen colostrum was more prevalent on large farms (80.8 vs 64.2 %). On 85.1 % of the farms, whole milk, including waste milk, was fed to the calves. Milk replacer and waste milk were more often used on large farms. In accordance with similar studies from other countries, calf diarrhoea was indicated as the most prevalent disease. Multivariable logistic regression analysis revealed that herd size was associated with calf diarrhoea and calf respiratory tract disease, with higher risk of disease on large farms. Furthermore, feeding waste milk to the calves was associated with increasing calf diarrhoea incidence on farm. In the final model with calf respiratory tract disease as outcome, respondents from organic farms reported less often a respiratory tract disease incidence of over 10 % compared with conventional farms [odds ratio (OR) 0.40, 95 % confidence interval (CI) 0.21-0.75] and farmers that housed calves individually or in groups after birth significantly reported more often to have an incidence of respiratory tract

    Poor livestock health conditions are associated with geochemical Pb anomalies on a farm approximately 40km east of Pretoria, South Africa. A generic risk assessment of drinking water for Bonsmara cattle obtained from three separate subterranean water sources on the farm, revealed the presence of several potentially hazardous constituents suspected for the development of adverse health effects in the herd. The two main symptoms of the herd, namely, severe haemorrhagic diarrhoea in calves and reproductive failure in cows, have been investigated. A selenium-induced copper deficiency was proposed as the main cause to the calf diarrhoea, due to complexing between high concentrations of Se, Mo, Hg and Pb in drinking water. It was also anticipated that such Cu deficiencies would lead to low systemic Se inducing hypothyroidism in the cows due to inadequate iodine activation required for thyroid hormone formation and consequently adversely affect reproduction. The anomalous Pb in borehole drinking water on the southem part of the farm, suggests a clear genetic link with the underlying geochemical Pb anomalies detected by means of an ongoing regional geochemical survey.

    Due to global warming and environment pollution because of widespread use of fossil fuels there are already tendencies to stabilize and decrease the consumption of these energy resources and take into use more renewable energy resources. Estonian Biofuels Association (EBA) is a non-profit association, which was founded on 8. of May 1998 in Tallinn. The EBA is an independent and voluntary alliance of its members. Fields of activity of the EBA are by biofuels research, developing and evaluation to engage environmental, biofuels and energy saving. EBA members are: energy consultants, scientists, as well as fuel suppliers, DH-companies, technology suppliers, energy service companies etc. The members of EBA are involved in different projects in Estonia, where biomass are produced and used for heating, where wood, waste, peat, rape oil and biogas resources are examined and put into use, and also projects which deal with energy saving and environment friendly equipment production for using biofuels. During our short experience we have noticed that people in Estonia have become more aware of biomass and their use, so the development of environment friendly and sustainable energetics will continue in Estonia. Available biofuels in Estonia could compete with fossil fuels if burnt rationally with high technology equipment. EBA members are convinced that biomass have perspective and that they could play an important role in improving Estonian economic and environmental situation. Modem biomass combustion devices are taken into use more the faster general wealth increases and EBA can raise people's awareness of bio fuel subject through special, courses and media. We want Estonian energy policy to develop towards widespread use of renewable energy resources, which would save energy and environment improve nation's foreign trade balance and create jobs mainly in rural areas

    Stream geomorphic characteristics were monitored along a 0.8-mile reach of the Fever River in the Driftless Area of southwestern Wisconsin from 2004 to 2011 where cattle grazed in paddocks along the riverbank at the University of Wisconsin-Platteville’s Pioneer Farm. The study reach encompassed seven paddocks that covered a total of 30 acres on both sides of the river. Monitoring data included channel crosssection surveys, eroding bank measurements and photograph points, erosion-pin measurements, longitudinal profile surveys, measurements of the volume of soft sediment in the channel, and repeated time-lapse photographs. Characteristics were summarized into subreaches by use of a geographic information system. From 2004 to 2007, baseline monitoring was done to identify geomorphic conditions prior to evaluating the effects of management alternatives for riparian grazing. Subsequent to the full-scale baseline monitoring, additional data were collected from 2007 to 2011. Samples of eroding bank and in-channel soft sediment were collected and analyzed for dry bulk density in 2008 for use in a sediment budget. One of the pastures was excluded from cattle grazing in the fall of 2007; in 2009 channel cross sections, longitudinal profiles, erosion-pin measurements, photographs, and a soft sediment survey were again collected along the full 0.8-mile reach for a comparison to baseline monitoring data. Channel cross sections were surveyed a final time in 2011. Lessons learned from bank monitoring with erosion pins were most numerous and included the need for consistent tracking of each pin and whether there was deposition or erosion, timing of measurements and bank conditions during measurements (frozen, postflood), and awareness of pins loosening in place. Repeated freezing and thawing of banks and consequential mass wasting and jointing enhance fluvial erosion. Monitoring equipment in the paddocks was kept flush to the ground or located high on posts to avoid injuring the

    Wild birds that forage around livestock facilities have been implicated as vectors of antimicrobial resistant organisms. Although antimicrobial resistant bacteria have been isolated from European starlings (Sturnus vulgaris), their role in the dissemination of antimicrobial resistant elements in livestock facilities needs further investigation. To determine whether on-farm starling density and other factors were associated with the presence of cefotaxime and ciprofloxacin resistant E. coli among dairy cows in Ohio, bovine fecal pats from 150 farms were tested for the presence of cefotaxime and ciprofloxacin resistant E. coli. Each farm was visited twice (during the summer and fall of 2007-2009). Multi-level logistic regression models with a random intercept to account for fecal pats collected within a specific visit to a farm were used to assess the associations. The percentage of samples with cefotaxime and ciprofloxacin resistant E. coli was 13.4% and 13.6%, respectively. The percentage of farms having at least one sample testing positive for cefotaxime and ciprofloxacin resistant E. coli was 56.7% and 48.7%, respectively. The odds of detecting cefotaxime and ciprofloxacin resistant E. coli in the samples was significantly higher in 2007 compared to 2008 and 2009, in fall compared to summer, and from farms closer than 60km to starling night roost sites compared to the farms further than 60km. The presence of starlings during the day had a negative association with the likelihood of detecting cefotaxime resistant E. coli. Presence of calves also had a negative association with the likelihood of detecting both cefotaxime and ciprofloxacin resistant E. coli. European starlings might play a role in the dissemination of antimicrobial resistant agents in livestock facilities related to their daily population movements rather than the specific density of birds on farm during the day.

    Full Text Available The goal of this project in Estonia was to determine what languages are spoken by students from the 2nd to the 5th year of basic school at their homes in Tallinn, the capital of Estonia. At the same time, this problem was also studied in other segregated regions of Estonia: Kohtla-Järve and Maardu. According to the database of the population census from the year 2000 (Estonian Statistics Executive Office's census 2000, there are representatives of 142 ethnic groups living in Estonia, speaking a total of 109 native languages. At the same time, the database doesn’t state which languages are spoken at homes. The material presented in this article belongs to the research topic “Home Language of Basic School Students in Tallinn” from years 2007–2008, specifically financed and ordered by the Estonian Ministry of Education and Research (grant No. ETF 7065 in the framework of an international study called “Multilingual Project”. It was determined what language is dominating in everyday use, what are the factors for choosing the language for communication, what are the preferred languages and language skills. This study reflects the actual trends of the language situation in these cities.

    In the end of the Soviet period in the 1980s, a long-term energy programme for Estonia was worked out. The energy system was planned to be based on nuclear power and the share of domestic alternative sources of energy was low. The situation has greatly changed after the re-establishment of the Estonian independence, and now wood and peat fuels play an important role in the energy system. Energy consumption in Estonia decreased during the period 1970-1993, but this process has less influenced the consumption of domestic renewable fuels - peat and wood. It means that the share of these fuels has grown. The investment on substitution of imported fossil fuels and on conversion of boiler plants from fossil fuels to domestic fuels has reached the level of USD 100 million. The perspectives of the wood energy depend mainly on two factors; the resources and the price of wood energy compared with other fuels. The situation in wood market influences both the possible quantities and the price. It is typical that the quickly growing cost of labour power in Estonia is greatly affecting the price of energy wood. Though the price level of fuel peat and wood chips is lower than the world market price today, the conditions for using biofuels could be more favourable, if higher environmental fees were introduced. In conjunction with increasing utilisation of biofuels it is important to evaluate possible emissions or removal of greenhouse gases from Estonian forests 3 refs.

    1999-01-01

    An on-farm survey was carried out to evaluate the nutritive value of the locally grown forages, the status of minerals in soils, forages and blood serum of cows and calves fed or grazed on these forages. The survey involves 55 smallholder farms practising zero- and grazing semi zero grazing dairy production systems in Bahati and Naivasha Divisions of Nakuru District. The samples of forage and crop residues and other feeds available at the farm level were analysed for dry matter (DM), crude protein (CP), acid detergent fibre (ADF), neutral detergent fibre (NDF), total lash and minerals-Ca, P, Mg, Na and Cu. Soil samples were analysed for pH, organic matter, Ca, P, Mg, Na and Cu. Samples of blood serum collected from the cows and calves utilising these forages were analysed for macro-elements-Ca, P, Mg, Na and trace elements such as Cu. Growth and production performance of the animals on these farms was studied. The results indicated a wide variation in the concentration of minerals in soils on different farms. Available feeds in these farms consisted of pasture, Napier grass and crop residues such as maize stovers. Pasture grasses and other established forages were deficient in protein ( - 1s), Na (316-339 ppm) and Cu (65- 120ppm) indicating the importance of mineral supplementation. The effect of age of the animal was significant for Cu (P 12.5%) and low milk production (< 10 kg per day) and low fertility suggesting the importance of protein, energy and mineral supplementation on the smallholder dairy farms of Bahati and Naivasha, possibly with concentrates and legumes which are rich in protein energy and minerals

    The major approaches of dairy cattle processing companies in the energy conservation are the milk extraction and milk cooling. The energy consumption can be significantly reduced by means of energy efficient plants such as frequency controlled vacuum pumps, preliminary cooling and heat recovery. Not only the consumption of electricity but also the consumption of water, the functional reality as well as the process quality should be considered. In the case of a new investment or replacement investment in energy saving plants, all influencing factors such as the present technology, the development of the company as well as the actual or planned energy supply of the company are to be considered.

    The Andean Páramos are high mountain ecosystems whose soils are essential for the management of South American water resources, but research on anthropic impacts to these soils is currently minimal and insufficient. The objective of this study was to evaluate the impacts of potato (Solanum tuberosum) cultivation and livestock on the physicochemical parameters and enzymatic activities that determine the soil quality of the Neotropical high Andean Páramo ecosystem in the Nevados National Natural Park (Nevados NNP) in Colombia. It was hypothesised that sites with potato crops and livestock farming would exhibit significant changes in soil physicochemical parameters and enzymatic activities compared with Páramo sites that have been conserved without agriculture. Samples were collected from soils under potato cultivation, livestock and Páramo (subject to the lowest degree of human intervention possible), on three farms in the El Bosque District at three different altitudes (Buenos Aires, El Edén and La Secreta) during two seasons (dry and rainy). The results showed that none of the physical parameters under study presented statistically significant differences due to the type of use (livestock, potato crop or Páramo), season of sampling (dry or rainy season) or altitude (different farms). The chemical parameters that statistically significantly differed due to land use were organic carbon, cation exchange capacity, calcium, potassium, and ammonium and those that showed statistically significant differences associated with the sampling timing were organic carbon, nitrogen, cation exchange capacity, total carbon, C/N and nitrate. Additionally, there were differences in organic carbon due to the altitude of the farms. With respect to enzymatic activities, those of β-glucosidase, phosphodiesterase and urease significantly decreased in soils under potato cultivation and livestock relative to those of Páramo, but those of acid phosphatase and protease increased

    Cattle feeders appear irrational when they place cattle on feed when projected profit is negative. Long futures positions appear to offer superior returns to cattle feeding investment. Cattle feeder behavior suggests that they believe a downward bias in live cattle futures persists and that cattle feeders use different expectations than the live cattle futures market price when making placement decisions. This study examines feeder cattle placement determinants, comparing performance of expec...

    The objective was to compare the relationships between luteal activity and fertility, and relate these parameters to metabolic indices and body condition changes in multiparous Estonian Holstein cows on two commercial dairy farms under different management and levels of production and nutrition (higher, H, n=54 (71 lactations) and lower, L, n=39 (39 lactations)). For statistical analysis cows were categorized according to their milk progesterone (P4) profiles as follows: normal ovarian function; delayed start of cyclicity (DC) (interval from calving to first luteal response (P45 ng/ml up to and more than 50 d respectively, followed by regular cyclicity); cessation of luteal activity (prolonged interluteal interval, P4bodies, non-esterified fatty acids, total cholesterol) and aspartate aminotransferase, body condition scores (BCS) and fertility parameters between the two farms, and also fertility parameters between the farms within P4 categories. Differences in milk fat/protein ratio, ketone body levels and BCS indicated a deeper negative energy balance (NEB) during the first month after calving on farm L. On both farms nearly 50% of the recently calved dairy cows suffered from ovarian dysfunction during the post-partum period. Delayed start of cyclicity was the most prevalent abnormal P4 profile, 25% and 28% on farms H and L, respectively. Prolonged luteal activity accounted for one-third of atypical ovarian patterns on farm H, and cessation of luteal activity on farm L. On farm L, DC cows had lower BCS values from day 10 to day 90 after calving compared with normal cows (Pcows lost more BCS (1.2 units) during the 40 d after calving than normal resumption cows (0.75 units; P<0.05). On farm H with moderate NEB the delayed start of ovulation post partum did not impair subsequent reproductive performance.

    Full Text Available Since its independence in 1991 Estonia has successfully overpassed the challenges of the transition period being in the present of one the most technologically developed nations of Europe. The present research is intended to evaluate the relationship between Estonian pro-market regulation, entrepreneurship and innovation. In order to reach relevant conclusions in this regard there have been used both qualitative and quantitative methods of analysis. In such a way, it could be comprehensively reviewed the process of Estonian economic development from a relatively underdeveloped USSR republic to an advanced innovation driven economy. The results show that pro-market governmental regulation has favourably influenced Estonian entrepreneurship, while it fostered country’s innovation capacities. It has been concluded that the economic “miracle” of Estonia has been at a great extent determined by proper government regulation oriented towards economic liberalisation.

    Full Text Available The study was focussed on the relationships between ethnic self-esteem and various indicators of intergroup attitudes in a representative sample of adult population of Estonia (N=1142. Attitudinal variables that discriminated most between persons with high and low ethnic self-esteem were identified. Among Estonians ethnic self-esteem was related to positive ingroup bias, readiness for outgroup contact, perceived threat from the outgroup, attitudes to non-Estonian minority, and attitudes toward minority integration. Among non-Estonians ethnic self-esteem was related to readiness for outgroup contact, ethnic sterotypes, and various attitudes towards minority integration. An attempt was made to reconstruct the system of intergroup attidues of prototypical persons with high and low ethnic selfesteem and to describe psychological implications of high and low ethnic self-esteem for members of majority and minority groups. Various theoretical models (social identity theory, integrated threat theory, social dominane theory were used for interpretation of the results.

    The Southern cattle tick, Rhipicephalus microplus is a hematophagous ectoparasite of great veterinary and economic importance. Along with its adaptability, reproductive success and vectoring capacity, R. microplus has been reported to develop resistance to the major chemical classes of acaricides currently in use. In South Africa, the Mnisi community in the Mpumalanga region offers a unique opportunity to study the adaptive potential of R. microplus. The aims of this study therefore included characterising acaricide resistance and determining the level and pattern of genetic diversity for R. microplus in this region from one primary population consisting of 12 communal dip-stations. The level of acaricide resistance was evaluated using single nucleotide polymorphisms (SNPs) in genes that contribute to acaricide insensitivity. Additionally, the ribosomal internal transcribed spacer 2 (ITS2) gene fragments of collected individuals were sequenced and a haplotype network was constructed. A high prevalence of alleles attributed to resistance against formamidines (amitraz) in the octopamine/tyramine (OCT/Tyr) receptor (frequency of 0.55) and pyrethroids in the carboxylesterase (frequency of 0.81) genes were observed. Overall, the sampled tick population was homozygous resistant to pyrethroid-based acaricides in the voltage-gated sodium channel (VGS) gene. A total of 11 haplotypes were identified in the Mnisi R. microplus population from ITS2 analysis with no clear population structure. From these allele frequencies it appears that formamidine resistance in the Mnisi community is on the rise, as the R. microplus populations is acquiring or generating these resistance alleles. Apart from rearing multi-resistant ticks to commonly used acaricides in this community these ticks may pose future problems to its surrounding areas. Copyright © 2016 Elsevier GmbH.

    The US regulations for production of organic milk include a strict prohibition against the use of antimicrobials and other synthetic substances. The effect of these regulations on dairy animal health has not been previously reported. The objective of this study was to characterize disease detection and identify risk factors for selected diseases on organic (ORG) and similarly sized conventional (CON) farms. Dairy herds (n=292) were enrolled across 3 states (New York, Oregon, Wisconsin) with CON herds matched to ORG herds based on location and herd size. During a single herd visit, information was collected about herd management practices and animal disease occurring in the previous 60 d, and paperwork was left for recording disease occurrences during 60 d after the visit. For analysis, CON herds were further divided into grazing and nongrazing. Poisson regression models were used to assess risk factors for rate of farmer-identified and recorded cases of clinical mastitis, ketosis, and pneumonia. An increased rate of farmer-identified and recorded cases of clinical mastitis was associated with use of CON management, use of forestripping, presence of contagious pathogens in the bulk tank culture, proactive detection of mastitis in postpartum cows, and stall barn housing. An increased rate of farmer-identified and recorded cases of ketosis was associated with having a more sensitive definition of ketosis, using stall barn housing, and feeding a greater amount of concentrates. An increased rate of farmer-identified and recorded cases of pneumonia was associated with a lack of grazing, small or medium herd size, and Jersey as the predominant breed. Overall, disease definitions and perceptions were similar among grazing systems and were associated with the rate of farmer-identified and recorded cases of disease.

    Full Text Available Abstract Background Objectives of the study were to document the impact of some management factors on the occurrence of clinical mastitis in primiparous dairy cows and to identify common udder pathogens of clinical mastitis in freshly calved heifers and multiparous cows on the day of calving. Methods A one-year study was conducted during 2004 and 2005 in 11 selected Estonian dairy herds. Data consisted of 68 heifers with clinical mastitis and 995 heifers without clinical mastitis on the day of calving. Multivariable logistic regression with a random herd effect was used to investigate any association between housing system or the time interval from movement of heifers to the calving facility and day of calving on occurrence of clinical mastitis. Milk samples for bacteriological analysis were collected from affected heifers and multiparous cows on the day of calving Results Clinical mastitis occurrence in the study population of freshly calved heifers equalled 6.1 %. Housing system was not a significant risk factor for clinical mastitis of freshly calved heifers. Moving heifers to the cowbarn less than two weeks before calving in tiestall farms increased risk (OR = 5.9 p = 0.001 for clinical mastitis at parturition. The most frequently isolated udder pathogens among heifers were Escherichia coli (22.1%, Streptococcus uberis (19.1% and coagulase-negative staphylococci (8.8%. In comparison, the main pathogen in multiparous cows with clinical mastitis at parturition was Staphylococcus aureus (11.2%. Conclusion Moving heifers to the calving facilities too late in tiestall farms increased risk for clinical mastitis at parturition. The isolated udder pathogens did not differ significantly in tiestall farms compared to freestall farms in heifers, but differences were found between heifers and multiparous cows at parturition.

    This report is the result of a survey on 564 cows subjected to artificial insemination (AI) from March 1995 to March 1996 in 4 districts around Ho Chi Minh City. Four inseminators filled in questionnaires relating to farms, semen batches, cows and inseminations done. Milk samples were collected and analysed for progesterone by radioimmunoassay (RIA). All raw data were stored and analysed by the computer program AIDA (Artificial Insemination Database Application). Conception rate at first service (FSCR) was 61.7% and overall conception rate (OCR) was 68.4%. The intervals from calving to first service (CSI) and calving to conception (CCI) were 108 days 119 days respectively. Cows with lower percentage of Holstein-Friesian (HF) blood had shorter CSI and CCI than those with higher percentage of HF blood. Other factors which influenced OCR, CSI and CCI were parity, high milk yield (>20 L/cow/day), inappropriate heat signs, slight degree of uterine tone, feeding without green grass, too early or too late intervals from heat signs to AI, time of AI and difficulty in passage of AI pipette. Progesterone measurement in 796 sets of milk samples indicated that AI in 546 cows (68.6%) resulted in conception and they were subsequently diagnosed pregnant, while 24 animals (3%) conceived but underwent late embryo mortality. In 146 cows (18.3%) AI was done in the follicular phase but conception did not occur. There were 73 cows (9.1%) where progesterone values were intermediate (1-3 nmol/L). Ninety-four Holstein crossbred cows (F1 and F2) were assigned into three groups by different metabolisable energy (ME) ratios between demand and supply in order to determine effect of nutritive value of rations on reproduction. The cows in ME-balanced group were also divided into two sub-groups by different quantity of green grass in the ration to evaluate influence of the latter on fertility. Results showed that only cows fed with balanced rations in ME achieved good fertility (calving to first

    Full Text Available This research aimed to study the relationships between livestock systems, landscape maintenance and farming styles in the Belluno Province, a mountainous area of the Eastern Italian Alps. A total of 65 farms were sampled on the basis of livestock category farmed and herd size. Farms were visited to collect information on technical and productive aspects, on landscape features of land managed, which was identified by aerial photographs and digitised in a GIS environment, and on the farmers’ background, attitudes and approach to farming. Six different livestock systems were identified: intensive beef cattle (2 farms; extensive beef cattle (12 farms; large sheep/goat farms (9 farms; small sheep/goat farms (6 farms; intensive dairy cattle (14 farms and extensive dairy cattle (22 farms. The intensive systems had larger herds, modern structures and equipment, and were strongly production oriented, whereas the extensive systems had smaller herds and productivity, with often traditional or obsolete structures and equipment, but showed a tendency to diversify production by means of on-farm cheese making and/or mixed farming of different livestock categories. The ability to maintain meadows and pastures was greater for the extensive systems, especially in steep areas, while the annual nitrogen output, estimated as kg N/ha, was lower. Data on the farmers’ background and attitudes were analysed with a non-hierarchical cluster procedure that clustered the farmers into 4 farming styles widely different in motivations to farming, innovative capability, and ability to diversify income sources and ensure farm economic viability. The farming styles were distributed across all livestock systems, indicating the lack of a linkage between the assignment of a farm to a livestock system and the way the farm is managed. This study demonstrates that in mountain areas variability of livestock systems may be high, and that they differ not only in production practices

    Two experiments were conducted on a commercial dairy farm to describe the effects of a reduction in Korral Kool (KK; Korral Kool Inc., Mesa, AZ) system operating time on core body temperature (CBT) of primiparous and multiparous cows. In the first experiment, KK systems were operated for 18, 21, or 24 h/d while CBT of 63 multiparous Holstein dairy cows was monitored. All treatments started at 0600 h, and KK systems were turned off at 0000 h and 0300 h for the 18-h and 21-h treatments, respectively. Animals were housed in 9 pens and assigned randomly to treatment sequences in a 3 × 3 Latin square design. In the second experiment, 21 multiparous and 21 primiparous cows were housed in 6 pens and assigned randomly to treatment sequences (KK operated for 21 or 24 h/d) in a switchback design. All treatments started at 0600 h, and KK systems were turned off at 0300 h for the 21-h treatments. In experiment 1, cows in the 24-h treatment had a lower mean CBT than cows in the 18- and 21-h treatments (38.97, 39.08, and 39.03±0.04°C, respectively). The significant treatment by time interaction showed that the greatest treatment effects occurred at 0600 h; treatment means at this time were 39.43, 39.37, and 38.88±0.18°C for 18-, 21-, and 24-h treatments, respectively. These results demonstrate that a reduction in KK system running time of ≥3 h/d will increase CBT. In experiment 2, a significant parity by treatment interaction was found. Multiparous cows on the 24-h treatment had lower mean CBT than cows on the 21-h treatment (39.23 and 39.45±0.17°C, respectively), but treatment had no effect on mean CBT of primiparous cows (39.50 and 39.63±0.20°C for 21- and 24-h treatments, respectively). A significant treatment by time interaction was observed, with the greatest treatment effects occurring at 0500 h; treatment means at this time were 39.57, 39.23, 39.89, and 39.04±0.24°C for 21-h primiparous, 24-h primiparous, 21-h multiparous, and 24-h multiparous cows

    The most comprehensive epidemiological project ever performed in Estonia - The Estonian Study of Chernobyl Cleanup Workers - was the joint effort of researchers from Estonia, Finland and USA. Until September 1999, the results of this study were published in English only. To familiarize the readership of 'Eesti Arst' with the major study findings, the abridged versions of four original papers from 'Radiation Research' are presented in the current issue of the journal. For the Estonian epidemiologists, the work under this project that consists of eight sub projects was a real challenge. In the course of the study, skills were developed in writing a study protocol, preparing a questionnaire, progress reporting, documenting the structure of databases, record linkage, and problem solving. It was an exciting experience to work with top scientists like William Bigbee, John Boice, Timo Hakulinen, Ronald Jensen and Gayle Littlefield. (author)

    Full Text Available The article reports the results of the study on the critical success factors and related information needs in Estonian industry conducted in 1999. Data were collected by interviews with 27 managers and engineers from 16 manufacturing companies in various industries. Most of the critical success factors taken up were related to marketing, information management, quality management, product development and technological innovations. The information needs of managers and engineers were related to competitors, customers, markets, technology, regulations, etc. Some identified CSFs expressed also priorities for development by Estonian economic authorities: to support the implementation of new technologies and introduction of quality management methods. The finding that information management was perceived as a very critical area supports the result of the recent Finnish study on CSFs.

    Full Text Available The diet of high-yield dairy cows process a very complex and acute problem. Much new knowledge in the area of production and preparation of feedstuffs, diet technology, and the interactions that occur between the components of the nutritive feed ration are required in order to resolve this problem. It is necessary constantly to coordinate feed norms with genetic potential which is ever changing and advanced. The observed problems must be resolved using multidisciplinary methods so that a diet can yield good health, and that health contribute to better reproduction and possibilities for more successful breeding and improved performance in cattle farming. In certain countries, thanks to their geographic position and climatic conditions which allow rainfall throughout the year, a natural green diet can be applied, which provides large numbers of green mass components, and with additives which can be supplemented relatively easily. This type of diet is not possible in our farms. It is very important to know which feedstuff components are laking for certain categories of cattle. The used ration must be constant and administered to animals of certain age or production characteristics in order to improve production results at cattle farms. A great problem occurs when diet is reduced due to dried grass and the resulting stress in animals. A 50% diet reduction in young cattle often results in the occurrence of respiratory diseases. Following 10-14 days of treatment, the disease disappears in young animals, but the energy deficit leads to the weakening (depression of the immune system. Even a so-called high-energy diet often causes respiratory diseases. A diet deficient in proteins also affects cows after lactation, as opposed to a normative diet, and a reduced protein diet disturbs the microbial activity in the rumen and the synthesis of compounds which are important for both the cow and the calf, making room for the incidence of metabolic diseases, most

    2011-01-01

    Full Text Available In April 2007, the Estonian Government moved a memorial commemorating the Soviet liberation of the country from the Nazis to a less prominent and visible location in Tallinn. This decision triggered rioting among Russian-speaking minorities and cyber terrorism targeting Estonia's critical economic and political infrastructure. Drawing upon the Estonian cyber attacks, this article argues that globalization and the Internet have enabled transnational groups—such as the Russian diaspora—to avenge their grievances by threatening the sovereignty of nation-states in cyberspace. Sophisticated and virtually untraceable political "hacktivists" may now possess the ability to disrupt or destroy government operations, banking transactions, city power grids, and even military weapon systems. Fortunately, western countries banded together to effectively combat the Estonian cyber attacks and minimize their effects. However, this article concludes that in the age of globalization, interdependence, and digital interconnectedness, nation-states must engage in increased cooperative cyber-defense activities to counter and prevent devastating Internet attacks and their implications.

    2010-12-01

    Full Text Available The article examines the exiled Estonian politicians in the European Movement in the early Cold War period. The ultimate goal of exiled Estonians was to restore their state’s independence. In order to promote this, Estonian leaders sought connections with Western leaders. The European Movement was the only organisation involving actors from both the East and the West, and this corresponded to the Estonian discourse on Europe as a whole. Therefore, the European Movement was appreciated, although its limited opportunities for decisive actions were also recognised. East and West European interest in the European Movement declined as West European integration rapidly intensified through the European Coal and Steel Community (ECSC and particularly after the January 1952 Eastern European Conference in London. By 1957, disappointment in the inability of European unification to help regain Estonian independence became evident.

    A survey of cattle dip facilities and current practices employed was done. Coumaphos and ethion were the commonly used acaricides in the four respondent stock farms. The behavior of coumaphos in a simulated model cattle dip was monitored using radiotracer techniques. Degradation was rapid, resulting in the formation of potasan metabolite and bound residues in the sediment. A rapid field method for the detection of organophosphate pesticides was used in monitoring the degradation of coumaphos in a cattle dip. The sensitivity of the method is comparable to the conventional HPLC method employed. This rapid field method can easily be used by cattle ranch owners to monitor coumaphos content of the vat facility so that recharging could be made in order to prevent the onset of resistance development in cattle tick.

    Directory of Open Access Journals (Sweden)

    Mägi, Vahur

    2013-03-01

    Full Text Available Casual mention of teaching technology subjects in Estonian schools dates back several centuries. Navigation and construction were amongthe earliest professional skills that were taught. As both of them required mathematical thinking skills, teaching the subjects was usually accompanied by explaining the principles of mathematics. The first technology book in Estonian was published about two centuries ago and it dealed with geodesy. The earliest Estonian glossaries of technological terminology were published in the fields of physics and chemistry. The rise of Estonian as a language of higher education and science in the country came about in the 1920s and 1930s. Faculty members of the Tallinn School of Technology then published the first textbooks composed in the Estonian language for students of technology. The Estonian Society for Technology and the Estonian Association of Engineers became seriously involved in linguistic activities. Together with the Vocational Teachers’ Assembly of Tartu they published an illustrated technology glossary for machinery and tools terms. It was followed by a glossary of construction and building terms, compiled under the lead of the University of Technology. In addition, journals of technology introducedinnovations in the lexicon of technology to the general public. The postwar period in the development of the lexicon of technical terms was of little significance at first. A surge in language creativity could be detected in the 1960s, when terminology became a target of constantly growing attention to the development of technology lexicon. Series of technology glossaries were published. This tendency has continued to this day.

    Full Text Available Bovine transhumance is characterized by the seasonal movement of livestock between winter and summer pastures. The system is well-known for Mediterranean countries, including Greece, where its role is multifunctional, because of its complex interactions with the environments and local societies. Unlike the dairy farming sector in Greece, whose salient features are the emergence of large-sized farms which are heavily dependent on fixed capital endowments and the provision of feedstuff, the transhumant system is much more flexible, by taking advantage of excessive family labor and by reducing feeding costs through grazing. The total number of transhumant farms in Greece has diminished during the last decades this farming system remains an essential activity in less favored areas of the country; the bovine cattle transhumant system, in particular, provides an efficient alternative to the capital-intensive dairy farming system. The purpose of this study is to provide a presentation of the current condition of the transhumant bovine cattle farming system in Greece. Through a survey of all relevant public services, data concerning the number of transhumant farms and animals as well as their movements in 2011 are presented. The survey reveals that the larger amount of transhumant farms is present in the lowlands of Thessaly and of East Macedonia-Thrace and move towards the mountainous rangelands of less favored areas, particularly those of West Macedonia. The mean transhumant bovine farm size does not exceed 100 animals, as nearly 76.1%, of the total rear less than 100 cattle. Thessaly is the region which accommodates the major part of transhumant farming in Greece; this is also the case for transhumant cattle, as 51.4% of all transhumant farms in the country have their winter domiciles in Thessaly.

    Pärna, K; Rahu, K; Rahu, M

    2005-05-01

    This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

  2. Acquisition of noun derivation in Estonian and Russian L1

    Reili Argus

    2018-04-01

    Full Text Available Acquisition of derivation is not a well-studied area in first language research and a comparative approach to the acquisition of derivation in different languages doesn’t exist. There is no information on how a child acquires derivation in a language with a rich and regular system of derivational patterns, or in a language where derivation is productive, but the system of derivational patterns is opaque. According to general ideas of complexity in a language, the child should start to use simplex stems first and, only after that, complex ones, that is, complexity should increase in the course of acquisition. Our paper is intended to address these issues, based on longitudinal child data from typologically different languages, Estonian and Russian. The results revealed significant differences in the acquisition of noun derivation in the two languages under observation. The system of noun derivation is acquired at a faster pace in Russian, while Estonian children have far fewer noun derivatives in their speech and they use different derivation suffixes with less regularity. Even so, the so-called building block model may be applied for both languages only partially.

    The lack of nationwide public databases on poisoning in cattle makes it difficult to investigate this issue. Hence, we conducted an epidemiological study using the data on cattle poisoning provided by an insurance company (2000-2005), to determine the mortality rate due to poisoning in cattle in Spain and to assess the influence of the following variables: type of farming, age, sex, time of year, year and region. We observed a mortality rate of 23.25 per 100,000 animals in Spain with a higher rate in beef than dairy cattle (32.14 vs. 4.51 per 100,000 animals). There were also differences in the mortality rate between breeding cattle and future breeders, affecting dairy and beef cattle in a different way. In dairy cattle, we found differences between the years analysed. In beef cattle, the time of year with highest risk of poisoning was the last quarter (19.45 per 100,000 animals), while the lowest mortality rate was observed in the first quarter (1.33 per 100,000). There were pronounced differences between regions in beef cattle, differences being non-significant in dairy cattle. Lastly, in beef cattle, no differences were found between sexes. In summary, the mortality rate due to poisoning in cattle in Spain is low, and the risk of poisoning is determined by the farming system, animals’ stage of development, time of year and region.

    When forming prices, Estonian peat companies' decisions should be based on marginal cost analysis. Unfortunately most Estonian companies sell peat to intermediaries and cannot influence its price. Estonian peat producers have to choose between either selling peat directly or selling through a central marketing organization. Both systems have their pros and cons. Direct selling gives more freedom to individual producers but is more risky. Central marketing makes cost saving possible and is more effective and stable, but may alienate producers from clients and markets. Whichever marketing system Estonian peat companies choose, the most important elements in their marketing strategy should be: careful market analysis, personal sales, attending trade shows, catalogues, quality service and offering transportation services.

    Full Text Available O objetivo do trabalho foi analisar os métodos de controle do carrapato Boophilus microplus realizados em três fazendas representativas dos sistemas de produção de leite da Microrregião Fisiográfica Fluminense do Grande Rio, Rio de Janeiro, levando-se em consideração o manejo das fazendas, o grau de sangue Bos taurus e Bos indicus dos rebanhos, os fatores climáticos e a prevalência estacional do carrapato. Para efeito de avaliação, foi utilizada a contagem periódica de fêmeas ingurgitadas medindo entre 4,5 e 8mm, no antímero direito de 20% das vacas em lactação de cada fazenda, durante um ano. A diferença no manejo das pastagens, a composição genética dos rebanhos e as condições climáticas influenciaram a prevalência estacional de B. microplus. A maior lotação animal por hectare, o elevado "stand" vegetativo das pastagens e o maior grau de sangue B. taurus contribuíram para as maiores infestações de carrapatos nas fazendas. O controle de B. microplus realizado pelos proprietários teve importância secundária em relação as outras atitudes de manejo dos rebanhos. Ficou evidenciado o uso excessivo e ineficiente de produtos químicos para o controle de B. microplus nas fazendas. Para implantação de medidas de controle estratégico do B. Microplus, fazem-se necessários esforços para a transferência e adoção dos resultados de pesquisas disponíveis aos produtores rurais.The objective of the study was to analyse the control methods of the cattle tick, Boophilus microplus.

    The cultural isolation and identification of leptospires from three water samples of farm wells were described. All three strains isolated belong to the apathogenic species L. biflexa. The cattle stock of these farms (A, B, C) had reacted serologically to serovars hardjo and grippotyphosa. The strain isolated from farm A is a new serovar called krefeldi and belongs to serogroup Doberdo. The strain isolated from farm B belongs to serovar montefiascone of serogroup Botanica and the strain from farm C to serovar bessemans of serogroup Bessemans. It is remarkable that serovar krefeldi with all the sera of farm A (titre up to 1:40) and only with part of the sera of farm B reacted.

    Cattle feeders appear irrational when they place cattle on feed when projected profits are negative. Long futures positions appear to offer superior returns to cattle feeding investment. Cattle feeder behavior suggests that they believe a downward bias in live cattle futures persists and that cattle feeders use different information than the live cattle futures market price when making placement decisions. This paper examines feeder cattle placement determinants and compares performance of ex...

    Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

    Full Text Available The purpose of this study is to investigate pathological changes in brain tissues of Frisien Holstein dairy cattle affected by organophosphate (OP. The study was directed to anticipate spongiform encephalopathy. Samples consisted of animal feeds, sera and brain tissues were collected from Lembang, West Java. Animal feeds (fodders and commercial feed were collected directly from the dairy farms around Lembang. Sera (31 samples were from dairy cattle owned by the local farmers and brain tissues were from the local animal slaughter house. Pesticide residues were analysed following a standard procedure using gas chromatography (GC. There was an interaction between pesticide residues in animal feeds, residue level of pesticides in sera and brain tissues to cause encephalopathy in dairy cattle. Pesticide contamination in animal feeds was regarded as the source of encephalopathy in dairy cattle. The total average of OP residues (16.8 ppb were lower than organochlorines/OC (18.7 ppb in fodder, showing that pesticides were originated from the contaminated soils. On the other hand, the total average of OP residues in commercial feeds (12.0 ppb, sera (85.6 ppb and brain tissues (22.7 ppb were higher than OC (1.8; 16.7; and 5.1 ppb. The OP appears more frequently used for dairy farm activity as insecticides. Histopathological examination for brain tissues of dairy cattle showed that most cattle were diagnosed as encephalopathy with microscopic changes of vacuolation, neuronal necrosis, chromatolysis of neurons and nucleolysis of neurons. The encephalopathy was confirmed in rats intoxicated with chlorpyrifos methyl as severe brain damage with spongiform-like lesions.

    The effects of management on the productivity of Bunaji cattle were investigated on 6 farms using 38 post-partum cows and 8 heifers. General information obtained on management of the farms indicated differences in managements practices between farms. The screening of the animals in the various farms for blood and endo-parasites showed that some of the farms had problems of helminthiasis and fascioliasis. Uterine involution was complete within 25 days of calving in all post-partum cows. Intervals from calving to ovulation and conception were different between farms. The conception rates for all farms over a period of 730 days ranged from 60 to 100%. A higher percentage of heifers on farm A reached puberty at an earlier age than those in farm B. It was concluded that management affects reproductive performance and thus productivity of Bunaji cattle, with nutrition and disease being the major contributing factors. (author). 10 refs, 7 tabs

    Full Text Available The Province of East Nusa Tenggara (NTT had been one of the major beef cattle suppliers under traditional management system in Indonesia. The beef cattle farming that based on grazing native pasture and the introduction of shrub legumes (Leucaena leucocephala may contribute to around 15 – 50% of the farmers’ household income. In the last few years, supply of beef cattle tended to decline due to the decrease in cattle population in NTT. Some basic improvements in management and feeding toward increasing beef cattle productivities had been carried out in Nusa Tenggara, such as a baseline survey on Cattle Health and Productivity Survey (CHAPS conducted in 1990 – 1992. The objective of the program was to identify the existing beef cattle productivity and health condition throughout Nusa Tenggara. A collaborative research with the Ministry of Research and Technology (Integrated Prime Research had also been carried out and the result showed that early weaning in Bali calves that can be practised as early as 3 – 6 months to prevent calves losses during the dry season. A program of the Assessment on Beef Cattle Base Farming Activities had also been conducted to improve fattening and breeding practices through the improvement in beef cattle management and feeding systems. At the latest development, fattening scheme has been introduced under a partnership approach involving private sectors and cooperatives. This needs to be facilitated by the government to accelerate the program such as access to capital and intensive extension services to build farmers awareness toward profit oriented beef cattle farming. Optimalization of the available potential resources and technology in NTT, will be an opportunity to enhance beef cattle production and gains back the reputation as one of the major producing beef cattle in the past. This will also support the national livestock program nowadays, called Beef Cattle Self Sufficiency Program 2014.

    Full Text Available The article examines how folk calendar holidays are represented in Estonian fairy tales. It introduces some views presented in folklore studies about the concept of time in fairy tales and finds parallels with them in the Estonian context. The analysis relies on the digital corpus of Estonian fairy tales (5400 variants, created from the texts found in the Estonian Folklore Archives by the Fairy Tale Project of the Department of Estonian and Comparative Folklore, University of Tartu. Folk calendar holidays occur in Estonian fairy tales relatively seldom; most often these are holidays that occupy a significant place in the Estonian folk calendar (Christmas, St. John’s Day, Easter, St. George’s Day. Calendar holidays are notably mentioned more often in tale types which remain on the borderline between the fairy tale and the legend or the fairy tale and the religious tale. In Estonian fairy tales, calendar holidays are used on three levels of meaning: (1 the holiday is organically associated with the tale type; it has an essential role in the plot of the tale; (2 to a certain extent, the holiday could be replaced by another holiday having an analogous meaning; (3 the holiday forms an unimportant or occasional addition to the tale.

  9. On the System of Place Name Signs in Estonian Sign Language

    Directory of Open Access Journals (Sweden)

    Liina Paales

    2011-05-01

    Full Text Available A place name sign is a linguistic-cultural marker that includes both memory and landscape. The author regards toponymic signs in Estonian Sign Language as representations of images held by the Estonian Deaf community: they reflect the geographical place, the period, the relationships of the Deaf community with hearing community, and the common and distinguishing features of the two cultures perceived by community's members. Name signs represent an element of signlore, which includes various types of creative linguistic play. There are stories hidden behind the place name signs that reveal the etymological origin of place name signs and reflect the community's memory. The purpose of this article is twofold. Firstly, it aims to introduce Estonian place name signs as Deaf signlore forms, analyse their structure and specify the main formation methods. Secondly, it interprets place-denoting signs in the light of understanding the foundations of Estonian Sign Language, Estonian Deaf education and education history, the traditions of local Deaf communities, and also of the cultural and local traditions of the dominant hearing communities. Both perspectives - linguistic and folkloristic - are represented in the current article.

    Understanding the practices of traditional cattle farmers in developing countries is an important factor in the development of appropriate, pro-poor disease control policies, and in formulating regional-specific production incentives that can improve productivity. This paper describes the production, husbandry practices, economics, and constraints of traditional cattle farming in Zambia. A cross-sectional study design was used to obtain data from traditional cattle farmers (n = 699) using a structured questionnaire. Data analyses were carried out using SPSS and STATA statistical packages. The results revealed that the majority [65% (95% CI: 59.3-71.1)] of farmers practised a transhumant cattle herding system under communal grazing. In these transhumant herding systems, animal husbandry and management systems were found to be of poor quality, in terms of supplementary feeding, vaccination coverage, deworming, uptake of veterinary services, usage of artificial insemination, and dip tanks all being low or absent. East Coast Fever was the most common disease, affecting 60% (95% CI: 56.4-63.7) of farmers. Cattle sales were low, as farmers only sold a median of two cattle per household per year. Crop farming was found to be the main source of farm income (47%) in agro-pastoralist communities, followed by cattle farming (28%) and other sources (25%). The median cost of production in the surveyed provinces was reported at US$316, while that of revenue from cattle and cattle products sales was estimated at US$885 per herd per year. This translates to an estimated gross margin of US$569, representing 64.3% of revenue.There is considerable diversity in disease distribution, animal husbandry practices, economics, and challenges in traditional cattle production in different locations of Zambia. Therefore, to improve the productivity of the traditional cattle sub-sector, policy makers and stakeholders in the beef value chain must develop fit-for-purpose policies and

    Bovine tuberculosis caused by Mycobacterium bovis is a serious and economically important disease of cattle. Badgers have been implicated in the transmission and maintenance of the disease in the UK since the 1970s. Recent studies have provided substantial evidence of widespread and frequent visits by badgers to farm buildings during which there is the potential for close direct contact with cattle and contamination of cattle feed. Here we evaluated the effectiveness of simple exclusion measures in improving farm biosecurity and preventing badger visits to farm buildings. In the first phase of the study, 32 farms were surveyed using motion-triggered infrared cameras on potential entrances to farm buildings to determine the background level of badger visits experienced by each farm. In the second phase, they were divided into four treatment groups; "Control", "Feed Storage", "Cattle Housing" and "Both", whereby no exclusion measures were installed, exclusion measures were installed on feed storage areas only, cattle housing only or both feed storage and cattle housing, respectively. Badger exclusion measures included sheet metal gates, adjustable metal panels for gates, sheet metal fencing, feed bins and electric fencing. Cameras were deployed for at least 365 nights in each phase on each farm. Badger visits to farm buildings occurred on 19 of the 32 farms in phase one. In phase two, the simple exclusion measures were 100% effective in preventing badger entry into farm buildings, as long as they were appropriately deployed. Furthermore, the installation of exclusion measures also reduced the level of badger visits to the rest of the farmyard. The findings of the present study clearly demonstrate how relatively simple practical measures can substantially reduce the likelihood of badger visits to buildings and reduce some of the potential for contact and disease transmission between badgers and cattle.

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m 3 , in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m 3 . In 1% of the dwellings the radon concentration exceeded 400 Bq/m 3 . The highest radon concentration found in the study was 1040 Bq/m 3 . Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m 3 , and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m 3 . The mean value for all Estonia dwellings is calculated to be 60 Bq/m 3 . Using

    Parasitic nematodes are one of the most important causes of production losses in most cattle-producing countries of the world. The aim of the present study is to make a through estimate of helminth and protozoan infection prevalence in dairy cattle around Taiwan. Coprological techniques, including direct fecal smear, simple flotation, and simple sedimentation, were used to detect gastrointestinal helminths and protozoan in dairy cattle. A total of 1259 rectal fecal samples were collected from Holstein dairy cattle at 94 farms in 13 counties in Taiwan. The overall prevalence of gastrointestinal parasitic infection was 86.9%. The infection rates of protozoa, nematodes, trematodes, and cestodes were 81.3%, 7.9%, 1.6%, and 0.6%, respectively. Among all parasites, Buxtonella sulcata (61.7%) was the most predominant one, followed with Cryptosporidium spp. (32.6%) and Eimeria spp. (11.8%). There were significant differences in the prevalence of protozoa and nematodes between different age groups and distributional area groups. The present study demonstrated that gastrointestinal parasitic infections occur frequently in dairy cattle around Taiwan, especially protozoan infections. The results indicated that a superior management system and regular anthelmintic treatment should be used for the control of parasitic infections in dairy cattle farms. Copyright © 2012.

    Accurate information on the geographic distribution of domestic animal populations helps biosecurity authorities to efficiently prepare for and rapidly eradicate exotic diseases, such as Foot and Mouth Disease (FMD). Developing and maintaining sufficiently high-quality data resources is expensive and time consuming. Statistical modelling of population density and distribution has only begun to be applied to farm animal populations, although it is commonly used in wildlife ecology. We developed zero-inflated Poisson regression models in a Bayesian framework using environmental and socioeconomic variables to predict the counts of livestock units (LSUs) and of cattle on spatially referenced farm polygons in a commercially available New Zealand farm database, Agribase. Farm-level counts of cattle and of LSUs varied considerably by region, because of the heterogeneous farming landscape in New Zealand. The amount of high quality pasture per farm was significantly associated with the presence of both cattle and LSUs. Internal model validation (predictive performance) showed that the models were able to predict the count of the animal population on groups of farms that were located in randomly selected 3km zones with a high level of accuracy. Predicting cattle or LSU counts on individual farms was less accurate. Predicted counts were statistically significantly more variable for farms that were contract grazing dry stock, such as replacement dairy heifers and dairy cattle not currently producing milk, compared with other farm types. This analysis presents a way to predict numbers of LSUs and cattle for farms using environmental and socio-economic data. The technique has the potential to be extrapolated to predicting other pastoral based livestock species. Copyright © 2017 Elsevier B.V. All rights reserved.

    2013-12-01

    Full Text Available The article analyses tale type The Woman as Wolf, which is one of the most popular folk tales in the Estonian Folklore Archives and is represented there both in the form of a fairy tale and in the form of a legend. The vast majority of the versions of The Woman as Wolf were written down in the first part of the 20th century within Estonia and where recorded from Estonians. The article introduces the content of the tale, the origin of the first records from the early 19th century, and the dissemination area of the tale, which remains outside Western Europe: apart from the Estonian versions there are Sami, Karelian, Vepsian, Livonian, Latvian, Lithuanian, Russian, Ukrainian and Belarusian versions. While in almost all the Estonian versions the main protagonist is transformed into a wolf, in most of the versions written down in other areas and ethnic groups, another animal or bird replaces the wolf. The author is of the opinion that the Finnic area is central to the distribution of the folk tale The Woman as Wolf. The animal the woman is transformed into in the plot would not have been a wolf in earlier times. The article provides an explanation why the wolf is predominant in Estonian written sources. For that purpose the ways in which the wolf and werewolf were perceived in earlier Estonian folk belief are introduced. At the end of the article interpretation of the folk tale is provided. The author states that the plot and some of the motifs found in this folk tale reflect the difficulties women had in submitting to the norms and values of patriarchal order within their society.

    Full Text Available The article concerns itself with the figure of the teacher in Estonian society. We do not concentrate on the educational system as a whole, but on one specific and crucial element in this apparatus - the teacher. We begin by offering a brief historical overview of the conditions of pedagogues in the 20th century before moving on to describe the adoption of neo-liberal free market policies since the 1990s and the effects these policies had and still have on education. Our main concern is to understand the teacher as an actor in power relations; to achieve this understanding we have selected as our examples 1 surveillance techniques in school environment that have direct relations to the state and the market; and 2 the 2012 educational workers' strike that made it quite clear that the teachers have been fixed to a position of wage workers. The overall and more abstract aim of the paper is to think about the social role of the teacher in Estonia.

    Full Text Available A theoretical model was developed to model the fate of two common pharmaceutical residues: diclofenac and ibuprofen in eight Estonian seaside cities that discharge their wastewaters directly into the Baltic Sea. The consumption rates of the active ingredients of diclofenac and ibuprofen from 2006-2014 were analysed. A decrease of 19.9% for diclofenac consumption and an increase of 14.1% for ibuprofen were found. The fate of diclofenac and ibuprofen were modelled by considering the human metabolism removal rate for pharmaceuticals, the removal rate of diclofenac and ibuprofen in activated sludge wastewater treatment plants (WWTP and annual flow rates. An average decrease from 1 to 0.8 µg/l (decrease of 20% for diclofenac and an increase from 11.4 to 13.4 µg/l (increase of 14.9% for ibuprofen for the concentration in the effluents of the WWTP were modelled. The model gives us a good overview about the theoretical concentrations of pharmaceutical residues in the environment and is helpful for evaluating environmental impacts.

  10. History of experimental psychology from an Estonian perspective.

    2007-11-01

    A short review of the development of experimental psychology from an Estonian perspective is presented. The first rector after the reopening of the University of Dorpat (Tartu) in 1802, Georg Friedrich Parrot (1767-1852) was interested in optical phenomena which he attempted to explain by introducing the concept of unconscious inferences, anticipating a similar theory proposed by Herman von Helmholtz 20 years later. One of the next rectors, Alfred Wilhelm Volkmann (1800-1878) was regarded by Edwin Boring as one of the founding fathers of the experimental psychology. Georg Wilhelm Struve (1793-1864) played an essential part in solving the problem of personal equations. Arthur Joachim von Oettingen (1836-1920) developed a theory of music harmony, which stimulated his student Wilhelm Friedrich Ostwald (1853-1932) to study colour harmony. Emil Kraepelin (1856-1926), the founder of modern psychiatry, is by far the most important experimental psychologist who has worked in Estonia. His successor Wladimir von Tchisch (1855-1922), another student of Wilhelm Wundt, continued Kraepelin's work in experimental psychology. The lives of Wolfgang Köhler (1887-1967), who was born in Reval (Tallinn), and Oswald Külpe (1862-1915), who graduated from the University of Dorpat, extended the link between the history of experimental psychology and Estonia. Karl Gustav Girgensohn (1875-1925), the founder of the Dorpat School of the psychology of religion, stretched the use of experimental methods to the study of religious experience.

    The disaster that happened at the Chernobyl nuclear power station in 1986 caused a sharp rise in radioactive pollution over an extensive area in the region of the Baltic Sea. To estimate the distribution and the concentration of Cs-137 and Sr-90 in Estonian ecosystems, samples of mushrooms, mosses, lichens and the upper horizons of soil were gathered from 63 test sites during 1991. We were particularly interested in the amounts of radionuclides in mushrooms because these are used as food by people. Dangerously high radionuclide concentrations were found in mushrooms gathered in North-East Estonia. Heightened concentrations were registered here and there all over the territory of Estonia, especially in mushrooms gathered in Central and South-Western Estonia. The Cs-137 content in mushrooms depends on its content in other components of the ecosystems, first and foremost on the concentrations of radiocaesium in mosses and litter, which, therefore, can be used as indicators in prognostication the radioactive pollution of mushrooms in a certain region. As Cs-137 migrates between various ecosystem components, it is necessary to check the radioactivity of the forest products used for food for still a number of years to come. The Sr-90 level was low in all the ecosystem components examined. (author). 3 figs., 10 refs

    Full Text Available With increasing concern about environmental burdens originating from livestock production, the importance of farming system evaluation has never been greater. In order to form a basis for trade-off analysis of pasture-based cattle production systems, liveweight data from 90 Charolais × Hereford-Friesian calves were collected at a high temporal resolution at the North Wyke Farm Platform (NWFP in Devon, UK. These data were then applied to the Intergovernmental Panel on Climate Change (IPCC modelling framework to estimate on-farm methane emissions under three different pasture management strategies, completing a foreground dataset required to calculate emissions intensity of individual beef cattle.

    The aim of the experiment was to determine the effects of supplementation of di-calcium-phosphate in the form of blocks in late pregnancy (2 months before calving), on production and reproduction parameters of dairy cattle in smallholder farms. The experiment covered 63 animals in 20 smallholder farms, divided into control and supplemented groups. Results showed that mineral supplementation had a significant effect on calf weight, milk fat content and reproduction parameters. Calves born to cattle supplemented with di-calcium-phosphate were heavier by 1.67 kg than those in the control group. Similarly, the average milk fat content in the supplemented group was 5.6 g/L (P 0.05). (author)

    2017-01-01

    The objective of this case-control study was to identify farm-level risk factors associated with bovine tuberculosis (bTB) in dairy cows in northern Thailand. Spatial analysis was performed to identify geographical clustering of case-farms located in Chiang Mai and Chiang Rai provinces in northern Thailand. To identify management factors affecting bTB status, a matched case-control study was conducted with 20 case-farms and 38 control-farms. Case-farms were dairy farms with at least single intradermal tuberculin test- (SIT-) reactor(s) in the farms during 2011 to 2015. Control-farms were dairy farms with no SIT-reactors in the same period and located within 5 km from case-farms. Questionnaires were administered for data collection with questions based on epidemiological plausibility and characteristics of the local livestock industry. Data were analyzed using multiple logistic regressions. A significant geographic cluster was identified only in Chiang Mai province (p < 0.05). The risk factor associated with presence of SIT-reactors in dairy herds located in this region was purchasing dairy cows from dealers (OR = 5.85, 95% CI = 1.66–20.58, and p = 0.006). From this study, it was concluded that geographic clustering was identified for dairy farms with SIT-reactors in these provinces, and the cattle movements through cattle dealers increased the risks for SIT-reactor farm status.

    2016-01-01

    Full Text Available The Busha is an indigenous breed of cattle in many Balkan countries. It has been bred for centuries. It belongs to primitive shorthorn cattle (Bos brachyceros europaeus. These cattle used to be the dominant and most important breed in almost all Balkan countries until the 1950s and 1960s, but today in lowland areas where intensive farming is practiced they have already been replaced by more productive and specialized breeds of cattle. In Macedonia this breed has officially been classified as a triple purpose breed (raised for meat, milk and draft but considering its low production capabilities it is more similar to some primitive draft breeds. This breed is part of the National Biodiversity Program for the conservation of indigenous breeds of animals in the Republic of Macedonia. Economic, cultural and scientific reasons underlie the need to protect the biological diversity of autochthonous breeds of cattle such as the Busha. The aim of the research was to establish a gene bank for different strains of adult Busha cattle in the Republic of Macedonia. To this end, 998 samples of blood, 1100 hair coat samples and 958 doses of semen were collected from adult Busha cattle. Also, a phenotypic characterization was done on adult Busha cattle for their major productive and morphological traits. During the last few years, there have been certain negative trends in the population size of Busha cattle in accordance with the decline of the rural population in the hills and uplands and young people's disinterest in rearing indigenous breeds of cattle such as the Busha.

The empirical part of the article compares the financing principles of Estonian municipalities with other EU countries. Finally, the proportions of different own sources of revenues in the budgets of Estonian local governments are examined and suggestions are made for changing the current system

  5. Arrested larval development in cattle nematodes.

    Armour, J; Duncan, M

    1987-06-01

    Most economically important cattle nematodes are able to arrest their larval development within the host - entering a period of dormancy or hypobiosis. Arrested larvae have a low death rate, and large numbers can accumulate in infected cattle during the grazing season. Because of this, outbreaks of disease caused by such nematodes can occur at times when recent infection with the parasites could not have occurred, for example during winter in temperature northern climates when cattle are normally housed. The capacity to arrest is a heritable trait. It is seen as an adaptation by the parasite to avoid further development to its free-living stages during times when the climate is unsuitable for free-living survival. But levels of arrestment can vary markedly in different regions, in different cattle, and under different management regimes. Climatic factors, previous conditioning, host immune status, and farm management all seem to affect arrestment levels. In this article, James Armour and Mary Duncan review the biological basis of the phenomenon, and discuss the apparently conflicting views on how it is controlled.

In total, seven pteromalid species were recovered: Spalangia cameroni Perkins, S. nigripes Curtis, S. subpunctata Förster, Muscidifurax raptorGirault & Sanders, Pachycrepoideus vindemiae (Rondani), Urolepis rufipes(Ashmead) and Nasonia vitripennis (Walker), an ichneumonid Phygadeuon fumator......Gravenhorst, a diapriid Trichopria sp., and a staphylinid Aleocharasp. This is the first time that U. rufipes has been recorded in Europe. Spalangia cameroni and M. raptor were the most frequently recorded species in all regions of the country, and accounted for the main parasitism of Musca domesticaand Stomoxys...... calcitrans puparia. The overall rate of parasitism per farm was low: 12.9% of the total number of fly puparia collected. Direct ordination, used to assess the habitat distribution of the parasitoids, showed that Muscidifurax raptor mainly seeks fly puparia in outdoor manure heaps and especially in manure...

    Beef cattle farm is an economic activity that its correlation relatively high with ecology condition, ever more its activity be dominated by smallholder with farm scale of 1—3 head beef cattle, so the capital of feeder cattle are component production costs relatively large. By doing so, lose one head of cattle means losing some of the capital that had been invested in its farm. This condition has implications for the behavior of farmers in managing its farm. The farmers in the decision-making act reluctant to risk so there is a bit of a program or package of new technologies to improve the performance of farm rejected. Therefore, this study analyzed the preferences of farmers against risks, and find out the socio-economic conditions that be the deciding factor on farmer preference for risk.The method used was a survey with multistage random sampling. The numbers of samples in this study were 150 people from three different areas, namely: District of Bandung, Subang, and Pangandaran (South Ciamis). Data analysis model used in relation to this research problem was the model’s utility function and Component Factor Analysis (CFA). The results showed that the overall breeders had a reluctant attitude to risk (risk averter). This is indicated by the value of x3, namely -63,692.693 < 0; and socio-economic factors that determine the preference of farmers against risk are age, education, and experience for farm management; while the business scale factor, number of dependents, and ownership determine the size of the gross margin.

    The article presents an overview of a research conducted in the Estonian Inst. of Economics and the Estonian Energy Research Inst. with the objectives to: analyse the dynamics of the main Estonian energy use indicators over the last 8-10 years with the background of general macroeconomics developments; compare these indicators with the respective energy indicators in the European Union Member States and Candidate Countries; evaluate Estonia's potential to catch up by the energy use efficiency (GDP energy intensity) of the average level of EU countries, modelling our possible development scenarios of GDP and TPES. The research results indicates several positive development tendencies (e.g. reduction of TPES and CO 2 emissions with the background of economic growth) in the Estonian energy sector, as well as convergence with the EU countries in terms of GDP energy intensity. Unfortunately, the model analysis results demonstrate that it takes a lot of time for Estonia to reach the current EU level - even under the most favourable GDP and TPES development conditions, 25-30 years. The primary reason is the very low level of our GDP per capita compared to the EU countries. (author)

    Full Text Available The article deals with the development in Russian-Estonian relations during the crises of 2007 and 2014, taking into consideration the balance between political and economic factors in the decision-making by Estonian government. A number of special aspects, trends and problems in trade and investment ties are detected. The aim of the study is to uncover key motivation behind the actions of both Russia and Estonia, to identify the drivers for economic and political development in the region, and to work out recommendations to adjust them. The questions put forward by the authors of this article could not be more topical at the time, when Russian economic situation is obviously getting worse and capital flight (to the neighboring EU Member States is likely to increase. The method of the study is comparative analysis of the impact on economic ties made by Russian-Estonian crisis of 2007 and the current international tension around Ukraine. The regional fossil fuel market and the possibilities of Gazprom involvement in its development are also analyzed. It is concluded that political motives are still important for Estonian decisionmaking, though they are balanced out by measures of business support (despite some of these measures being taken by the EU bodies. The role of political factor for the Russian side is increasing. It is acknowledged that there is a growing number of missed economic opportunities in the Russian Northwest.

    2011-01-01

    The concept of organisational culture (also referred to later as OC) is one of the approaches in modern organisational analysis exploring the values, attitudes and beliefs behind human behaviour in the workplace. OC as a social phenomenon is considered to be important for the sustainability of every organisation. In the service sector, OC may affect the nature and quality of the services provided. The aim of this paper is twofold: on the one hand, to highlight the patterns of OC in a hospital; and, on the other hand, to outline relationships between OC and patient satisfaction. The study was conducted in Tartu University Hospital, one of the most influential health care organisations in Estonia. This paper has original value by presenting an insight into organisational culture in the Estonian health care sector, and the findings of the study will expand knowledge of OC in the health care sector in general. The OC instrument applied in a quantitative cross-sectional study was earlier developed according to the Competing Values Framework (CVF). Data from 456 medical and non-medical professionals were analysed using non-parametric tests of descriptive statistics. A factor analysis was performed to assess the instrument's compatibility for analysing the OC pattern in the health care sector. The dominant culture type in all the groups investigated was the Internal Processes type, mainly followed by the Rational Goal type, while different cultural patterns were observed in professional groups. The factor analysis yielded a three-subscale solution. Clinics with high patient satisfaction did not score more than clinics with low patient satisfaction in terms of the Human Relations type. In future studies a random sample design and a multidisciplinary approach to OC research should be followed in order to further explore OC patterns in hospitals and their consequences for different aspects of hospital performance.

    As energy demand and prices continue to grow, oil shale might help mitigate the energy crisis—it can widely be found all over the world but so far has not been widely used. Estonia is unique in the world for producing a large majority of energy out of oil shale and has been set as an example in numerous papers covering oil shale deposits, technology etc. This paper is the first to analyse oil shale energy related workforce and provides scenario forecasts of the labour demand for the Estonian energy sector in 2010–2020. The contribution of the paper is twofold. First, the paper provides a valuable insight into oil shale energy related workforce, enabling to take into consideration the educational needs in countries where oil shale industry might be set up. Second, methodology-wise, the paper relates labour demand and supply to different scenarios of energy production capacities. The results illustrate problems related to aging of the workforce in energy production. If the existing trends continue in educational attainment in Estonia, there will be a serious shortage of high-skilled engineering and manufacturing specialists. Our method provides a simple yet reliable enough way to check for such problems early enough. - Highlights: ► This paper analyses oil shale energy related workforce and provides scenario forecasts. ► This is the first study to investigate the workforce related to oil shale energy production. ► The main workforce-related problem in the sector is ageing of the workforce. ► Workers immigrating to the sector during the Soviet times are at the retirement age. ► There will be a serious shortage of engineers for energy sector in the near future.

    2017-09-01

    Full Text Available This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association, but also professional values, the whole occupational ideology and the conditions of the existence of journalism as a profession in Estonia.

    Full Text Available This article begins by examining points of intersection between two professional theatres, ”Estonia” and ”Vanemuine” (both established in 1906, their young directors – Karl Menning, Paul Pinna, Theodor Altermann, and Karl Jungholz, and the literary movement Young Estonia. Subsequently, we will consider Young Estonia’s theatrical ideals and the influence of these ideas on later Estonian theatrical life. Since not much information has survived regarding direct personal contacts between ”movers and shakers” in the theatre world and Young Estonians, the main focus here shall be on indirect creative connections and influences. One such context is education: like the Young Estonians, theatre activists of the younger generation aspired to place themselves on the larger map of European culture. Thus, their artistic beliefs and goals shall be examined in relation to those of Young Estonians’ quest for modern culture. Pinna, Altermann, Menning, Jungholz, and others went on study tours to Germany and France, where they were energized and inspired by innovative German and Russian theatres, by naturalistic staging, and by psychological realism, both in acting and in performance style. Among their models were A. Antoine’s Théâtre- Libre in Paris, K. Stanislavski’s Art Theatre in Moscow, O. Brahm’s Lessing-Theater, and M. Reinhardt’s Deutsches Theater in Berlin. These models were likewise known to the Young Estonians, but if theatre activists oriented themselves more fundamentally to German naturalist and realist dramatic art, Young Estonians were more taken with ”theatrical theatre” with its symbolist and impressionist influences. The Young Estonians attended performances at both theatres, ”Vanemuine” and ”Estonia”, and wrote numerous theatre reviews. Yet in the Young Estonia albums (yearbooks and in the magazine Young Estonia, theatre topics have a relatively modest representation. Young Estonians did not have direct

    Wei Zhao

    Full Text Available Cattle are the main reservoir host of C. andersoni, which shows a predominance in yearlings and adults of cattle. To understand the subtypes of C. andersoni and the population genetic structure in Heilongjiang Province, fecal specimens were collected from 420 dairy cattle and 405 beef cattle at the age of 12-14 months in eight cattle farms in five areas within this province and were screened for the presence of Cryptosporidium oocysts by microscopy after Sheather's sugar flotation technique. The average prevalence of Cryptosporidium spp. was 19.15% (158/825 and all the Cryptosporidium isolates were identified as C. andersoni by the SSU rRNA gene nested PCR-RFLP using SspI, VspI and MboII restriction enzymes. A total of 50 C. andersoni isolates were randomly selected and sequenced to confirm the RFLP results before they were subtyped by multilocus sequence typing (MLST at the four microsatellite/minisatellite loci (MS1, MS2, MS3 and MS16. Four, one, two and one haplotypes were obtained at the four loci, respectively. The MLST subtype A4,A4,A4,A1 showed an absolute predominance and a wide distribution among the six MLST subtypes obtained in the investigated areas. Linkage disequilibrium analysis showed the presence of a clonal population genetic structure of C. andersoni in cattle, suggesting the absence of recombination among lineages. The finding of a clonal population genetic structure indicated that the prevalence of C. andersoni in cattle in Heilongjiang Province is not attributed to the introduction of cattle. Thus, prevention and control strategies should be focused on making stricter measures to avoid the occurrence of cross-transmission and re-infection between cattle individuals. These molecular data will also be helpful to explore the source attribution of infection/contamination of C. andersoni and to elucidate its transmission dynamics in Heilongjiang Province, even in China.

    1931-01-01

    Estonian oil shale is one of the oldest and richest oil shales in the world. The deposits occur in the Middle-Ordovician strata having a total thickness of 2.2 meters. The ultimate composition of the kerogen varied within the following limits: carbon 76.5 to 76.7 percent, hydrogen 9.1 to 9.2 percent, nitrogen 0.2 to 0.4 percent, sulfur 1.6 to 2.2 percent, chlorine 0.5 to 0.7 percent, and oxygen (by difference) 11.2 to 12.2 percent. The composition of kukersite kerogen corresponds nearly to the empirical formula (C/sub 8/H/sub 11/O)n. One of the most significant differences between kukersite, coal, and lignite is the amount of alkali-soluble substances present. Kukersite has almost no humic acids. Samples of kukersite were brominated and chlorinated. The halogenated shales showed a solubility in absolute alcohol of 26 percent compared to only 0.31 percent for untreated shale. Enriched shale (4.5 percent ash) did not react with chlorine as much as did raw shale. Apparently the mineral matter acted catalytically during chlorination. The amount of soluble extract obtained by solvent treatment of kukersite ranged from 0.22 percent with chloroform to 2.20 percent with tetrachloroethane. Heat was the most effective agent for the depolymerization of kukersite kerogen. The percentage loss of weight due to drying in air was much less than in the presence of carbon dioxide. The results indicated that on drying in air, the powdered shale loses water and a volatile substance, probably the oxides of carbon, up to 80/sup 0/C. Carbon dioxide was also found to be present in the gases eliminated at the temperature of initial decomposition. Pulverized shale, heated for 6 hours at 220/sup 0/C, lost 2.6 percent of its weight; its solubility in carbon disulfide was 2.11 percent. Kukersite kerogen was formed from compounds that were resistent to bacteriological decomposition, such as waxes and resins, plus decomposition products of proteins, cellulose, and putrefaction products of

    2006-10-01

    This paper presents the results of the distribution of trace elements in Estonian mires. Sixty four mires, representative of the different landscape units, were analyzed for the content of 16 trace elements (Cr, Mn, Ni, Cu, Zn, and Pb using AAS; Cd by GF-AAS; Hg by the cold vapour method; and V, Co, As, Sr, Mo, Th, and U by XRF) as well as other peat characteristics (peat type, degree of humification, pH and ash content). The results of the research show that concentrations of trace elements in peat are generally low: V 3.8 ± 0.6, Cr 3.1 ± 0.2, Mn 35.1 ± 2.7, Co 0.50 ± 0.05, Ni 3.7 ± 0.2, Cu 4.4 ± 0.3, Zn 10.0 ± 0.7, As 2.4 ± 0.3, Sr 21.9 ± 0.9, Mo 1.2 ± 0.2, Cd 0.12 ± 0.01, Hg 0.05 ± 0.01, Pb 3.3 ± 0.2, Th 0.47 ± 0.05, U 1.3 ± 0.2 μg g - 1 and S 0.25 ± 0.02%. Statistical analyses on these large database showed that Co has the highest positive correlations with many elements and ash content. As, Ni, Mo, ash content and pH are also significantly correlated. The lowest abundance of most trace elements was recorded in mires fed only by precipitation (ombrotrophic), and the highest in mires fed by groundwater and springs (minerotrophic), which are situated in the flood plains of river valleys. Concentrations usually differ between the superficial, middle and bottom peat layers, but the significance decreases depending on the type of mire in the following order: transitional mires - raised bogs - fens. Differences among mire types are highest for the superficial but not significant for the basal peat layers. The use of peat with high concentrations of trace elements in agriculture, horticulture, as fuel, for water purification etc., may pose a risk for humans: via the food chain, through inhalation, drinking water etc.

    Animal traction constitutes the most important source of power for agricultural work in smallholder farming in Zimbabwe. Two studies, a survey and a short term on-farm trial were conducted to evaluate the use of donkeys as draught animals. The survey covered 59 households in 2 smallholder farming areas. For the on-farm trial, 12 donkeys and 12 cattle were spanned separately in teams of 4 animals to plough 40 m x 70 m plots of medium textured soil. The survey findings highlighted the drought tolerance of donkeys compared to cattle. Mortality rates of donkeys were lower. Results of the draught performance trial indicated that donkeys ploughed less area per day (P draught force between the 2 species. The work rate per hour for ploughing with donkeys was 65% of that of cattle. It was concluded that donkeys play a critical role in providing draught power for smallholder farmers but that their potential is not fully utilised.

    It is general knowledge that management influences results in cattle production to the highest extent, and that the culling of cows is a very good indicator of the success of farm management. A comparison of results of culling for first calving cows on farms with various levels of production in 2011 established differences both for the number of culled animals and the reasons for culling. On farms with higher levels of production, the share of first calving...

    Full Text Available Bovine neosporosis caused by the apicomplexan protozoan parasite N. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. The aim of this study was to determine the seroprevalence of N. caninum infection in industrial dairy cattle of Hamedan province (west of Iran by ELISA method. Blood samples were collected from 492 cattle in 41 farms. Antibodies to N. caninum were found in 63(12.80% sera. A Significant difference was observed between seropositive cattle and dog presence in farm, dog contact with herd, abortion history and herd population. No significant differences were found between seropositive cattle and age as well as breed. This study is the first report of N. caninum infection in dairy cattle farms in Hamedan province. As per our knowledge, Neospora is an important factor in abortion of cattle in this region. Therefore, comprehensive studies for control strategies and improving management of dairy farms is necessary.

    Full Text Available While pathogenic types of Escherichia coli are well characterized, relatively little is known about the commensal E. coli flora. In the current study, antimicrobial resistance in commensal E. coli and distribution of ERIC-PCR genotypes among isolates of such bacteria from cattle and cattle attendants on cattle farms in Tanzania were investigated. Seventeen E. coli genomes representing different ERIC-PCR types of commensal E. coli were sequenced in order to determine their possible importance as a reservoir for both antimicrobial resistance genes and virulence factors. Both human and cattle isolates were highly resistant to tetracycline (40.8% and 33.1%, sulphamethazole-trimethoprim (49.0% and 8.8% and ampicillin (44.9% and 21.3%. However, higher proportion of resistant E. coli and higher frequency of resistance to more than two antimicrobials was found in isolates from cattle attendants than isolates from cattle. Sixteen out of 66 ERIC-PCR genotypes were shared between the two hosts, and among these ones, seven types contained isolates from cattle and cattle attendants from the same farm, suggesting transfer of strains between hosts. Genome-wide analysis showed that the majority of the sequenced cattle isolates were assigned to phylogroups B1, while human isolates represented phylogroups A, C, D and E. In general, in silico resistome and virulence factor identification did not reveal differences between hosts or phylogroups, except for lpfA and iss found to be cattle and B1 phylogroup specific. The most frequent plasmids replicon genes found in strains from both hosts were of IncF type, which are commonly associated with carriage of antimicrobial and virulence genes. Commensal E. coli from cattle and attendants were found to share same genotypes and to carry antimicrobial resistance and virulence genes associated with both intra and extraintestinal E. coli pathotypes.

    A survey was conducted to better understand the contribution of farm productivity to rural household income and identify differences in production systems, feeding practices and development constraints to smallholder beef cattle producers in the four agro-ecological zones (AEZs) of Cambodia. A semi-structured questionnaire was used to interview 360 households in the four AEZs: I, the Great Lake Floodplain; II, the Mekong Floodplain; III, the Coastal and IV, the Plateau/Mountainous. In addition, samples of common nutritional resources used for cattle feed were collected for nutrient composition analysis, plus cattle were scored for body condition. Rice farming and cattle production were the most common sources of income in all AEZs. The average cattle herd size was 3.7 (SD = 2.4), but the majority of households raised 1-3 animals. The most common cattle management system was grazing with supplementation, mainly with rice straw and 'cut-and-carry' natural grasses fed during the wet season in all AEZs. The body condition score of all cattle types was 3.2 (SD = 0.8), except for cows in lactation that were 1.8. Major constraints to cattle production in AEZs I, II and III were lack of quality feed resources, capital for cattle production and concerns on breed quality, whereas in AEZ IV, diseases were identified as the main constraint. This survey confirms the importance of cattle to smallholders in the four AEZs. Interventions including farmer education to improve husbandry skills, increase the utilisation of forages and crop residues and address disease issues are necessary to enhance cattle production and rural livelihoods in Cambodia.

    Full Text Available The objective of this paper is to report a smart dairy farming in Ontario, Canada, which is a case study for future of food production, and ways that advancements related to the Internet of Things (IoT. It is impacting upon agricultural practice in the form of smart farming. Smart farming is the practice of intelligent agricultural management based upon technological data gathering farm practice for the purpose of increased levels of quality, production, and environmental protection. This paper will illustrate one example whereby partnerships among the academic world, government agencies and local food producing communities in Canada are adapting innovative thinking and smart technologies to address the need to implement the more effective agricultural practice. Food from Thought is a Canadian research project, based upon high-tech information systems to produce enough food for a growing human population while sustaining the Earth’s ecosystems. The paper will outline how one dairy farmer in Ontario has been able to apply smart farming technologies to increase milk production while maintaining the health of his cattle and preserving the environment. The review of applications of smart farming in Ontario such as digital tracking for a cow, genomic testing, digitally signaled birth, sensor driven crop management and data driven dairy production also details in this article.

    Based on a survey data collected from 150 farming households in Dano district of western Showa of Ethiopia, this paper analyzes determinants of smallholders' choice for market oriented indigenous Horo cattle production and tries to suggest policy alternatives for sustainable use of animal genetic resource in the study area. Descriptive statistics and binary logistic model were employed to analyze the data. Eight explanatory variables including age of the household head, size of the grazing land, total size of cultivated land, farmer's experience in indigenous cattle production, farmer's attitude towards productivity of local breed, off-farm income, fattening practice, and availability of information and training of the head of the household regarding conservation, management and sustainable use indigenous cattle were found to be statistically significant variables to explain farmers' choice for market oriented indigenous cattle production activities. Besides, possible policy implications were made in order to improve conservation, management and sustainable use of market oriented indigenous cattle genetic resources.

Group B received strategic treatment (ivermectin 3.15% at the beginning and at the end of the rainy period. Eggs per gram of feces (EPG counts and genus of larvae from fecal cultures were determined on a monthly basis from April 2002 to December 2003. There was no significant reduction (p > 0.05 in EPG counts in any group after anthelminthic treatment, and the larvae in fecal cultures observed were Cooperia, Haemonchus, Oesophagostomum and a few Trichostrongylus. Cooperia was the most prevalent genus in the first four months of the experiment and Haemonchus in the following months. In 2003, tracer calves were introduced onto the pastures monthly and they showed high nematode burden many times throughout the year, and Cooperia punctata and Haemonchus contortus were the main species identified. The results suggest that there is anthelminthic resistance in this farm, mainly to macrocyclic lactones, and the development of immunity by crossbred animals was vital to reduce nematode burden.Oitenta e quatro bezerras meio sangue Gir × holandês (F1 com seis meses de idade, naturalmente infectadas por helmintos gastrintestinais e mantidas em pastejo rotacionado receberam diferentes tratamentos anti-helmínticos.

    A cross-sectional study was conducted to determine the presence of brucellosis in cattle, goats and humans in farms from south-western Uganda and identify risk factors associated with brucellosis in these three host groups. Data and serum samples were collected from 768 cattle, 315 goats and 236 humans, with 635 samples of bovine milk, from 70 farms in two different study areas in south-western Uganda. Sera from livestock were tested with the Rose Bengal Plate test, using B. abortus and B. melitensis antigens, and human sera were tested with a commercial IgG/IgM lateral flow assay. Milk samples were tested using the OIE-approved milk ring test. Screening tests for brucellosis were positive in 14% of cattle serum, 29% of bovine milk, 17% of goat serum and 11% of human serum samples. There were significant differences in the test prevalence of brucellosis by study site, with levels higher in the study area near Lake Mburo National Park than in the study area near Queen Elizabeth National Park. Multivariable regression models identified risk factors associated with increasing test positivity at the individual and farm levels for cattle, goats and humans. Positive associations were seen between increasing seropositivity of brucellosis in goats, cattle and humans. Results of multivariable analyses suggest that improvements in farm biosecurity and hygiene may reduce the risk of brucellosis on the farm and suggest a role for ticks in bovine brucellosis. Although cattle are the focus of brucellosis control in Uganda, the significant associations between seropositivity in humans and seropositivity in goats suggest that brucellosis in goats may be an important contributor to the epidemiology of the disease on the farm. © 2015 Blackwell Verlag GmbH.

    Full Text Available This paper focuses on the meanings assigned to Tatar language among the Tatar diaspora in Estonia. According to interviews with Estonian Tatars as well as descriptions of field material from Tatarstan, language is an important aspect of Tatar ethnic identity. This paper will track common discourses about the Tatar language and the way it is connected to Tatar ethnic identity. Issues concerning Tatar language are used to demonstrate various ways of enacting Tatarness in Estonia. It is shown that Estonian Tatars worry about the vitality and purity of Tatar language, but for some, marginalization of dialects is also an issue. People categorized with the same identity labels by self and others can experience and enact their Tatarness in a variety of different ways.

    This case study of the Estonian Genome Project (EGP) analyses the Estonian policy decision to construct a national human gene bank. Drawing upon qualitative data from newspaper articles and public policy documents, it focuses on how proponents use discourse to link the EGP to the broader political goal of securing Estonia's position within the Western/European scientific and cultural space. This dominant narrative is then situated within the analytical notion of the "brand state", which raises potentially negative political consequences for this type of market-driven genomic research. Considered against the increasing number of countries engaging in gene bank and/or gene database projects, this analysis of Estonia elucidates issues that cross national boundaries, while also illuminating factors specific to this small, post-Soviet state as it enters the global biocybernetic economy.

Layoffs have increased the number of unemployed; some of those who have lost employment opt for social assistance benefits, but some others decide to become entrepreneurs. Many enterprising people in Estonia have set up a family enterprise, mainly in the sphere of services, agriculture and tourism. The Estonian entrepreneurship policy supports enterprising people and approves of entrepreneurship as a promoter of national economic development. One of the most positive qualities of family enterprises is their short decision-making chain, which ensures rapid implementation of the strategy.

    Fasciolosis caused by Fasciola hepatica is responsible for major production losses in cattle farms. The objectives of this study were to assess the effect of farm management practices on liver fluke prevalence on Irish dairy farms and to document the current control measures against parasitic diseases. In total, 369 dairy farms throughout Ireland were sampled from October to December 2013, each providing a single bulk tank milk (BTM) sample for liver fluke antibody-detection ELISA testing and completing a questionnaire on their farm management. The analysis of samples showed that cows on 78% (n=288) of dairy farms had been exposed to liver fluke. There was a difference (P0.05) between positive and negative farms in (a) the grazing of dry cows together with replacement cows, (b) whether or not grazed grassland was mowed for conservation, (c) the type of drinking water provision system, (d) spreading of cattle manure on grassland or (e) for grazing season length (GSL; mean=262.5 days). Also, there were differences (Pmanagement practices between Irish farms with dairy herds exposed or not exposed to liver fluke and stressed the need of fine-scale mapping of the disease patterns even at farm level to increase the accuracy of risk models. Also, comprehensive advice and professional support services to farmers on appropriate farm management practices are very important for an effective anthelmintic control strategy.

    The work was aimed at determining the number and morphology of nucleoli in the prophase of the first meiotic division in domestic cattle males. The use of AgNO₃ staining, commonly applied in cytogenetics for the identification of nucleolar organiser regions, made it possible to identify nucleoli in first-order spermatocytes. One nucleolus was identified in each analysed cell. Considerable morphological differentiation of the nucleoli during the prophase of the first meiotic division, particularly in leptotene, unobserved in other farm animal species, was noticed. Dark-hued grain-like structures were found within the disintegrating nucleoli, corresponding approximately or exactly to the number of the nucleolar organiser regions in the domestic cattle karyotype. Dark areas were identified in the selected prometaphase chromosomes. Their number corresponded with the number of active NORs defined in the domestic cattle karyotype.

  17. Is Estonian oil shale beneficial in the future?

    Reinsalu, Enno

    1998-01-01

    Oil shale mining production reached its maximum level of 31.35·10 6 tonnes per year in 1980. After the eighties there was a steady decline in mining. The first scientific prognoses of the inescapable decrease in oil shale mining were published in 1988. According to this, the Estonian oil shale industry would vanish in the third decade of the next century. From the beginning of the nineties, the consumption and export of electricity have dropped in Estonia. The minimum level of oil shale mining was 13.5·10 6 tonnes per year. This occurred in 1994/1995. Some increase in consumption of electric power and oil shale began at the end of 1995. Oil shale processing began to increase gradually in 1993. Oil shale is the most important fuel in Estonia today. In 1997, oil shale provided 76% of Estonia's primary energy supply and accounted for 57% of its economic value. Oil shale is the cheapest fuel in Estonia. Nowadays, oil shale provides an essential part of the fuel supply in Estonia because it is considerably cheaper than other fuels. Oil shale costs EEK 12.16 per G J. At the same time, coal costs EEK 23.41 per G J and peat costs EEK 14.80 per G J (year 1997). There are three important customers of oil shale: the electric power company Eesti Energia, the oil processing company Kiviter and the factory Kunda Nordic Cement. In 1995, the power company utilised 81% of the oil shale mass and 77% of its heating value. The state energy policy inhibits increases in the oil shale price even though the mining infrastructure is decaying. Government price policies subside oil shale processing. The energy of oil shale processing is 1.9 times cheaper than the heating value of raw oil shale for power stations. It could be considered as a state subsidisation of oil and cement export at the expense of electricity. The subsidy assigned to oil processing was of EEK 124·10 6 and to the cement industry of EEK 8.4·10 6 in year 1997 (based on heating value). State regulation of prices and

    Full Text Available Dairy cattle reared in western Kenya are exposed to medium to high levels of trypanosomosis risk. The social background, farm characteristics and dairy cattle productivity of 90 and 30 randomly selected farmers from medium- and high-risk trypanosomosis areas, respectively, were compared. All the 120 farmers were visited between July and August 2002. Data analysis was performed using descriptive statistics and analysis of variance. The results showed that increased trypanosomosis risk represented by an increase in disease prevalence in cattle of 1% to 20 % decreased the density of dairy cattle by 53 % and increased the calving interval from 14 to 25 months. The increased risk was also associated with a significant increase in cattle mortalities and in a lactation period of 257 to 300 days. It was concluded that removal of the trypanosomosis constraint on dairy production would lead to expansion of dairying since the domestic demand for dairy products is expected to increase.

    The huge changes in agricultural activities, which may be amplified by the forthcoming Common Agriculture Policy reform, call the future of crop-livestock systems into question and hence the impact of these changes on landscapes and biodiversity. We analyzed relationships between agriculture, landscape and biodiversity in south-western France. The study area covered about 4,000 ha and included four villages. We conducted a survey of 56 farms. Multivariate analysis (multiple factor analysis and cluster analysis) were used to analyze relationships between 25 variables and to build a typology. The type of farming (beef and/or dairy cattle, cash crops), size (area and workforce) and cultivation practices, among others, were revealed as differentiating factors of farms. Six farming types were identified (1) hillside mixed crop-livestock farms, (2) large corporate farms, (3) extensive cattle farms, (4) large intensive farms on the valley sides, (5) small multiple-job holdings, and (6) hobby farms. The diversity of farming systems revealed the variable impact of the main drivers of change affecting agricultural development, particularly the enlargement and modernization of farms along with the demography of agricultural holdings.

    We present data from an observational cohort study on human immunodeficiency virus (HIV) prevention and control measures in prisons in Estonia to assess the potential for HIV transmission in this setting. HIV testing and retesting data from the Estonian prison health department were used to estimate HIV prevalence and incidence in prison. Since 2002, voluntary HIV counselling and testing has routinely been offered to all prisoners and has been part of the new prisoners health check. At the end of 2012, there were 3,289 prisoners in Estonia, including 170 women: 28.5% were drug users and 15.6% were infected with HIV. Of the HIV-positive inmates, 8.3% were newly diagnosed on prison entry. In 2012, 4,387 HIV tests (including retests) were performed in Estonian prisons. Among 1,756 initially HIV-negative prisoners who were in prison for more than one year and therefore tested for HIV twice within 12 months (at entry and annual testing), one new HIV infection was detected, an incidence of 0.067 per 100 person-years (95% confidence interval (CI): 0.025–5.572). This analysis indicates low risk of HIV transmission in Estonian prisons. Implementation of HIV management interventions could impact positively on the health of prisoners and the communities to which they return.

    Despite diagnostic and therapeutic advancements, the burden of cancer is still increasing worldwide. Toxicity of current chemotherapeutics to normal cells and their resistance to tumor cells highlights the urgent need for new drugs with minimal adverse side effects. The use of natural anticancer agents has entered into the area of cancer research and increased efforts are being made to isolate bioactive products from medicinal plants. To lead the search for plants with potential cytotoxic activity, ethnopharmacological knowledge can give a great contribution. Therefore, the attention of this review is devoted to the natural remedies traditionally used for the cancer treatment by Estonian people over a period of almost 150 years. Two massive databases, the first one stored in the Estonian Folklore Archives and the second one in the electronic database HERBA ( http://herba.folklore.ee/ ), containing altogether more than 30 000 ethnomedicinal texts were systematically reviewed to compile data about the Estonian folk traditional experiences on natural anticancer remedies. As a result, 44 different plants with potential anticancer properties were elicited, 5 of which [Angelica sylvestris L. (Apiaceae), Anthemis tinctoria L. (Asteraceae), Pinus sylvestris L. (Pinaceae), Sorbus aucuparia L. (Rosaceae), and Prunus padus L. (Rosaceae)] have not been previously described with respect to their tumoricidal activities in the scientific literature, suggesting thus the potential herbal materials for further investigations of natural anticancer compounds.

    To compare smoking behaviour, attitudes and opinions towards smoking and smoking cessation among Estonian and Finnish physicians. A cross-sectional postal survey using a self-administered questionnaire was carried out among 2,480 Estonian and 2,075 Finnish physicians. Daily smoking prevalence was higher among Estonian physicians than among their Finnish counterparts in both male (18.6% and 6.7%) and female (6.6% and 3.6%). Compared to Estonia, physicians in Finland more often agreed that smoking is very harmful to their health, that trying to convince people to stop smoking is their responsibility and that smoking prevention should be part of the normal and special training of health professionals. In both countries, non-smoking physicians held more unfavourable attitudes towards smoking than those who were smoking. Physicians' own smoking patterns and quitting behaviour are important because physicians serve as models for their patients and play a key role in the reinforcement of smoke-free health facilities. These results remain a challenge to medical educators, especially in Estonia. Estonia needs to improve medical education in terms of motivating physicians to ask about the smoking patterns of their patients and of training medical students and resident physicians to counsel their patients to stop smoking.

    The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

    Full Text Available The 2006 FAO report concerning the environmental impact of the livestock sector has generated scientific debate, especially considering the context of global warming and the need to provide animal products to a growing world population. However, this sector differs widely in terms of environmental context, production targets, degree of intensification and cultural role. The traditional breeding systems in the Alps were largely based on the use of meadows and pastures and produced not only milk and meat but also other fundamental positive externalities and ecosystem services, such as conservation of genetic resources, water flow regulation, pollination, climate regulation, landscape maintenance, recreation and ecotourism and cultural heritage. In recent decades, the mountain livestock, mainly represented by dairy cattle, has been affected by a dramatic reduction of farms, a strong increase of animals per farm, an increase in indoor production systems, more extensive use of specialised non-indigenous cattle breeds and the increasing use of extra-farm concentrates instead of meadows and pastures for fodder. This paper firstly describes the livestock sector in the Italian Alps and analyses the most important factors affecting their sustainability. Secondly, it discusses the need to assess the ecosystem services offered by forage- based livestock systems in mountains with particular attention to greenhouse gas emission and its mitigation by carbon sequestration. In conclusion, comparison between the different elements of the environmental sustainability of mountain livestock systems must be based on a comprehensive overview of the relationships among animal husbandry, environment and socio-economic context.

    Full Text Available Background and Aim: The Ogaden cattle is one among the tropical cattle breeds (Bos indicus widely distributed in eastern and south eastern part of Ethiopia. The breed has been evolved in arid and semi arid agro-ecological setup, but later on distributed and adapted to the wide agro-ecological zones. Because of its multi-purpose role, the Ogaden cattle have been used for milk, beef, and income generation. Information on the inherent genetic diversity is important in the design of breeding improvement programmes, making rational decisions on sustainable utilization and conservation of Animal Genetic Resources. Limited information is available about genetic variation of Ogaden breed at molecular level. The present investigation was aimed to study the biochemical polymorphism at the Hemoglobin (Hb locus. Materials and Methods: Blood samples collected from 105 Ogaden cattle maintained at Haramaya beef farm by jugular vein puncture were subjected to agarose gel electrophoresis [pH range 8.4-8.5] to study the polymorphic activities of haemoglobin. Results: Three types of phenotypes were detected i.e. a slow moving (AA band, fast moving (BB band and a combination of slow + fast moving bands (AB. The frequency of the fast moving band was less [13 (12.3%] than the slow moving band [57 (54.2%]. Both slow & fast moving phenotype was observed in 35 (33.3% animals. The gene frequency of HBA allele was 0.709 and that of HBB allele 0.291. Conclusion: The distribution of phenotypes was in agreement with codominant single gene inheritance. The Chi-square (χ2 test revealed that the population is under Hardy-Weinberg equilibrium.

  13. Greenhouse Gas Emissions From Cattle

    Directory of Open Access Journals (Sweden)

    Podkówka Zbigniew

    2015-03-01

    Full Text Available Cattle produce greenhouse gases (GHG which lead to changes in the chemical composition of the atmosphere. These gases which cause greenhouse effect include: methane (CH4, nitrous oxide (N2O, nitrogen oxides (NOx, sulphur dioxide (SO2, ammonia (NH3, dust particles and non-methane volatile organic compounds, commonly described as other than methane hydrocarbons. Fermentation processes taking place in the digestive tract produce ‘digestive gases’, distinguished from gases which are emitted during the decomposition of manure. Among these digestive gases methane and non-methane volatile organic compounds are of particular relevance importance. The amount of gases produced by cows can be reduced by choosing to rear animals with an improved genetically based performance. A dairy cow with higher production efficiency, producing milk with higher protein content and at the same time reduced fat content emits less GHG into the environment. Increasing the ratio of feed mixtures in a feed ration also reduces GHG emissions, especially of methane. By selection of dairy cows with higher production efficiency and appropriate nutrition, the farm's expected milk production target can be achieved while at the same time, the size of the herd is reduced, leading to a reduction of GHG emissions.

    Social capital plays an important role in the development of poultry farms in South Sulawesi. Poultry farms consisted of laying hen and broiler farms. Most of laying hen farms were located in Sidrap Regency, while broiler farms were located in Maros regency. The aim of this research was to know social capital on beef cattle farms in South Sulawesi. Population of this research was 120 farmers which consisted of 6o were laying hen farmers and 60 were broiler farmers. Variable of social capital was mutual trust, reciprocity, shared norms and linkage. The data were collected from observation and depth interview by using questionnaire. There were 10 questions. The answer was scored by using Likert scale ranging from 1 refer to strongly agree; 2 refer to agree; 3 refer to not sure; 4 refer to disagree and 5 refer to strongly disagree. The data were analyzed descriptively using frequency distribution. The research revealed that mutual trust and shared norms members of the group in broiler farms have higher level than that on laying hen farms, on the other hand, linkage or net working members of the group among laying hen farmers has higher level than that on broiler farms.

    Full Text Available Classification of specialized farms applying multivariate statistical methods The paper is aimed at application of advanced multivariate statistical methods when classifying cattle breeding farming enterprises by their economic size. Advantage of the model is its ability to use a few selected indicators compared to the complex methodology of current classification model that requires knowledge of detailed structure of the herd turnover and structure of cultivated crops. Output of the paper is intended to be applied within farm structure research focused on future development of Czech agriculture. As data source, the farming enterprises database for 2014 has been used, from the FADN CZ system. The predictive model proposed exploits knowledge of actual size classes of the farms tested. Outcomes of the linear discriminatory analysis multifactor classification method have supported the chance of filing farming enterprises in the group of Small farms (98 % filed correctly, and the Large and Very Large enterprises (100 % filed correctly. The Medium Size farms have been correctly filed at 58.11 % only. Partial shortages of the process presented have been found when discriminating Medium and Small farms.

    Full Text Available Three case studies involving Leptospira interrogans serovar pomona outbreaks within mixed farming systems in South Africa are described. On 2 farms, pigs constituted the main enterprise with cattle and sheep of secondary importance. On each of these 2 farms, abortion due to L. pomona in sows was confirmed by culture, and antibody titres to pomona were detected in cattle, sheep, horses and dogs. On the 3rd farm, a piggery was ofsecondary importance to cattle farming. Abortion and death in cows occurred on this farmand serology showed titres to various serovars, including pomona. L. pomona was also isolated from bovine urine, an aborted bovine foetus and kidneys from slaughtered pigs. This particular case study was regarded as clinically atypical in that adult Jersey cattle died of acute leptospirosis in a semiarid region of South Africa. In all 3 case studies, the poor management of pig effluent and of the drinking water and its sources played a pivotal role in the transmission of the disease. Inadequate vaccination of animals against Leptospira and poor record-keeping within the secondary farming enterprises were also contributing factors to the spread of leptospirosis.

    Full Text Available The welfare state of cattle in dairy farms in Macedonia has never been assessed previously. The objective of this study was to perform screening analysis of dairy cows welfare and to test the practical implementation of the Welfare Quality® Assessment protocol for cattle in dairy farms in Macedonia. In ten small scale and large scale tie stall farms 23 measures were recorded related to 9 welfare criteria of 4 welfare principles (WP described in the Welfare Quality® Assessment protocol for dairy cows. The mean percentage of very lean cows was 40.5±9.1%. All assessed farms were not providing access to pasture and an outdoor loafing area. Regarding cleanliness, the presence of dirty udder, upper leg/flank and lower leg was 65.2±9.0%, 85.5±8.0% and 86.5±5.8%, respectively. The overall prevalence of lameness was 5.6±5.0%, and for mild and severe alterations it was 30.8±5.8% and 54.1±4.6%, respectively. The ocular and vulvar discharge, diarrhea, dystocia, percentage of downer cows and mortality rate exceeded the warning and alarm threshold. The avoidance – distance test classified 70.4±6.8% as animals that can be touched or approached closer than 50cm, with overall score of 42.9±3.5. This screening reveals that the most welfare concerns are found in the WP Good Feeding and Good Housing. The on-farm welfare assessment using the full protocol on a representative sample of farms in the country is highly recommended for emphasizing the key points for improving the animal welfare in Macedonian dairy farms.

  1. Dynamical patterns of cattle trade movements.

    Directory of Open Access Journals (Sweden)

    Paolo Bajardi

    Full Text Available Despite their importance for the spread of zoonotic diseases, our understanding of the dynamical aspects characterizing the movements of farmed animal populations remains limited as these systems are traditionally studied as static objects and through simplified approximations. By leveraging on the network science approach, here we are able for the first time to fully analyze the longitudinal dataset of Italian cattle movements that reports the mobility of individual animals among farms on a daily basis. The complexity and inter-relations between topology, function and dynamical nature of the system are characterized at different spatial and time resolutions, in order to uncover patterns and vulnerabilities fundamental for the definition of targeted prevention and control measures for zoonotic diseases. Results show how the stationarity of statistical distributions coexists with a strong and non-trivial evolutionary dynamics at the node and link levels, on all timescales. Traditional static views of the displacement network hide important patterns of structural changes affecting nodes' centrality and farms' spreading potential, thus limiting the efficiency of interventions based on partial longitudinal information. By fully taking into account the longitudinal dimension, we propose a novel definition of dynamical motifs that is able to uncover the presence of a temporal arrow describing the evolution of the system and the causality patterns of its displacements, shedding light on mechanisms that may play a crucial role in the definition of preventive actions.

  2. Risk factors for Toxoplasma gondii infection in sheep and cattle from Fernando de Noronha Island, Brazil

    Directory of Open Access Journals (Sweden)

    Fernando Jorge Rodrigues Magalhães

    Full Text Available Abstract Toxoplasmosis is a zoonotic disease of global distribution that affects all warm-blooded animals. The purpose of this investigation was to determine the prevalence of T. gondii infection and identify the risk factors associated with its occurrence in domestic ruminants raised on the island of Fernando de Noronha, Brazil, and to confirm that cattle and sheep raised in Fernando de Noronha Island present statistically different T. gondii prevalence rates. Serum samples were collected from sheep (n=240 and cattle (n=140 for the detection of antibodies by indirect immunofluorescence. Samples were collected from all the animals on all the farms. Risk factors were analyzed by univariate analysis and logistic regression. The prevalence rate of positive sheep was 85.0% while that of cattle was 10.7%. A multivariate analysis revealed that the site of contact of sheep with felines was a risk factor. For cattle, the risk factors identified in this study were: extensive farming system, water source, more than three cats per farm, and the presence of rats in feed storage locations. The findings revealed a significant difference in the prevalence rates in sheep and cattle raised in this insular environment.

  3. Occurrence of ESBL-Producing Escherichia coli in Livestock and Farm Workers in Mecklenburg-Western Pomerania, Germany.

    Carmen Dahms

    Full Text Available In recent years, extended-spectrum β-lactamases (ESBL producing bacteria have been found in livestock, mainly as asymptomatic colonizers. The zoonotic risk for people working in close contact to animal husbandry has still not been completely assessed. Therefore, we investigated the prevalence of ESBL-producing Escherichia spp. in livestock animals and workers to determine the potential risk for an animal-human cross-transmission.In Mecklenburg-Western Pomerania, northeast Germany, inguinal swabs of 73 individuals with livestock contact from 23 different farms were tested for ESBL-producing Escherichia spp. Two pooled fecal samples per farm of animal origin from 34 different farms (17 pig farms, 11 cattle farms, 6 poultry farms as well as cloacal swabs of 10 randomly selected broilers or turkeys were taken at each poultry farm. For identification, selective chromogenic agar was used after an enrichment step. Phenotypically ESBL-producing isolates (n = 99 were tested for CTX-M, OXA, SHV and TEM using PCR, and isolates were further characterized using multilocus sequence typing (MLST. In total, 61 diverse isolates from different sources and/or different MLST/PCR results were acquired. Five farm workers (three from cattle farms and two from pig farms harbored ESBL-producing E. coli. All human isolates harbored the CTX-M β-lactamase; TEM and OXA β-lactamases were additionally detected in two, resp. one, isolates. ESBL-producing Escherichia spp. were found in fecal samples at pig (15/17, cattle (6/11 and poultry farms (3/6. In total, 70.6% (24/36 of the tested farms were ESBL positive. Furthermore, 9 out of 60 cloacal swabs turned out to be ESBL positive. All isolated ESBL-producing bacteria from animal sources were E. coli, except for one E. hermanii isolate. CTX-M was the most prevalent β-lactamase at cattle and pig farms, while SHV predominated in poultry. One human isolate shared an identical MLST sequence type (ST 3891 and CTX-M allele to the

  6. Evidence of Cryptococcosis in cattle in Zaria Kaduna state, Nigeria

    Directory of Open Access Journals (Sweden)

    Emmanuella N. Akange

    2013-04-01

    Full Text Available Aim: Cryptococcosis is azoonotic infection caused by fungal of the Cryptococcus neoformans complex comprising of C. neoformans and C. gattii.The disease affects humans and animals worldwide causing morbidity and mortality. This work was carried out to determine the occurrence of cryptococcal antigens and factors associated with presence of antigens in cattle in Zaria, Nigeria. Materials and Methods: Three hundred and ninety (390 serum samples from cattle of various ages were collected from 11 farms in Zaria, Nigeria. The samples were analysed using alatex agglutination test and lateral flow assay kit which detectsthe polysaccharide capsular antigens of Cryptococcus species. Results:Out of the 390 samples tested 28 (7.17% were found to be positive using the latex agglutination test while only of these 22 (5.64% were positive using the lateral flow assay. There was a strong correlation (r=0.939, p=0.0002 between the results of the latex agglutination test and the lateral flow assay. There was no statistically significant difference (p>0.005 in positivity for cryptococcal antigens between sex, age and sex, though, there was a statistically significant difference (p<0.05 in positivity between management systems i.e. semi-intensive and intensive farming systems. Conclusions: The epidemiological value of this report lies in its demonstration that the risk of cattle and humans infection with cryptococcosis exist in farms in Zaria. The presence of this pathogen among these cattle poses an economic threat to the livestock industry due to the mastitis it causes. It also poses a significant public health threat because of its zoonotic nature and the increasing population of immunocompromised individuals. Large scale studies to determine specific risk factors and the role of the environment and experimental studies to determine what governs the transition from nasal colonisation to infection are recommended.

    The objective of this study was to evaluate management characteristics on organic and similarly sized conventional dairy farms located in New York, Wisconsin, and Oregon. Data from 192 organic farms (ORG), 64 conventional nongrazing farms (CON-NG), and 36 conventional grazing farms (CON-GR) were collected during farm visits and were size-matched and analyzed. The average lactation number of animals on ORG and CON-GR farms was 2.6 lactations, which was greater than that on CON-NG farms (2.3 lactations). A greater percentage of first-lactation heifers were found on conventional farms than on ORG farms. Facilities used by adult animals, including housing and milking facilities, did not differ among the grazing systems. Cattle on conventional farms were fed approximately twice as much grain as cattle on ORG farms and had greater milk production. Little difference was found for the average reported somatic cell count and standard plate count, suggesting that milk quality is not dependent on grazing system. Milking procedures were similar across all 3 grazing systems, indicating that an industry standard now exists for milking and that milk quality problems will need to be addressed with other management problems in mind. Although some disease prevention measures were commonly utilized on ORG farms, such as keeping a closed herd and having a written record of treatments administered to the animals, the use of outside support and vaccinations were found to be less prevalent on organic farms than on conventional farms.

    Soil organic carbon (SOC) determines ecosystem functions, influencing soil fertility, soil physical, chemical and biological properties and crop productivity. Therefore the spatial pattern of SOC stocks and its appropriate management is important at various scales. Due to climate change and the contribution of carbon store in the soils, the national estimates of soil carbon stocks should be determined. Estonian soils have been well studied and mapped at a scale 1:10,000. Previous studies have estimated SOC stocks based on combinations of large groups of Estonian soils and the mean values of the soil profile database, but were not embedded into the geo-referenced databases. These studies have estimated SOC stocks of Estonian arable soils 122.3 Tg. Despite of available soil maps and databases, this information is still very poorly used for spatial soil modelling. The aim of current study is to assess and model spatial pattern of SOC stocks of arable soils on a pilot area Tartu County (area 3089 sq km). Estonian digital soil map and soil monitoring databases are providing a good opportunity to assess SOC stocks at various scales. The qualitative nature of the initial data from a soil map prohibits any straightforward use in modelling. Thus we have used several databases to construct models and linkages between soil properties that can be integrated into soil map. First step was to reorganize the soil map database (44,046 mapping units) so it can be used as an input to modelling. Arable areas were distinguished by a field layer of Agricultural Registers and Information Board, which provides precise information of current land use as it is the basis of paying CAP subsidies. The estimates of SOC content were found by using the arable land evaluation database of Tartu from the Estonian Land Board (comprising 950 sq km and 31,226 fields), where each soil type was assessed separately and average SOC content grouped by texture was derived. SOC content of epipedon varies in

    Full Text Available Fertiliser use in small-holder peri-urban crop-livestock farms in Uganda was investigated by conducting a socio-economic survey of 40 farms in the central districts of Wakiso and Kampala where cattle manure is commonly applied to address the issue of declining crop yields. The major benefits obtained from cattle manure application were increased yields and low cost, while negative effects were poor hygienic conditions and bad odour. The challenges associated with the use of cattle manure included its weight and bulkiness, lack of labour, insufficient quantities, high transportation and application costs, lack of storage facilities to maintain quality attributes of manure and the incidence of chaffer grubs and worms; a nuisance during application which affected crop growth. The survey indicated that of the farmers using cattle manure, only 5% also supplemented with inorganic fertilisers. Other animal manures applied included poultry, pig, goat and rabbit where available. The nutrient content of cattle manure was generally low, as a result of livestock diet and storage. There was little education available to farmers as to optimum strategies and rates of fertiliser (including both inorganic and organic fertilisers to improve crop yield and this needed addressing to improve food security and economic development in Uganda.

    Bovine vaccinia (BV) is a zoonosis caused by Vaccinia virus (VACV) that mainly affects lactating cows and dairy farm milkers. The epidemiological role(s) of other cattle categories such as dry cows, bulls, and heifers in BV remains unclear. This study was performed to investigate VACV in affected dairy cattle herds and perifocal farms during an outbreak in Brazil. Crusts from lesions of cows' teats were collected from all farms with BV outbreaks. Milk, feces, blood, and serum were collected from symptomatic and asymptomatic lactating cows. Blood and serum were also sampled from other cattle categories (calves, heifers, dry cows, and bulls). The samples were tested for VACV by PCR, and to confirm VACV viability, VACV-positive samples were inoculated in BSC-40 cells and stained using immunoperoxidase. Neutralizing antibodies were investigated using plaque reduction neutralization test. Viral DNA was detected in milk, blood, and feces samples of symptomatic and asymptomatic dairy cows and in blood samples from other cattle categories on farms with and without confirmed BV outbreak. In affected farms, viable virus was identified in feces and milk samples from lactating cows and in blood samples from asymptomatic dry cows. Viable VACV was also identified in feces from lactating cows and one bull's blood sample from perifocal farms. Neutralizing antibodies were detected in 81.6% of the herds affected by BV and in 53.8% of the herds on perifocal farms. The presented data indicate a potential source of viral dissemination, which contributes to the persistence and spread of VACV in the environment. Copyright © 2017 Elsevier Ltd. All rights reserved.

  18. Conservation and Improvement Strategy for Fogera Cattle: A Lesson for Ethiopia Ingenious Cattle Breed Resource

    Full Text Available The paper is initiated to design appropriate conservation strategies and breeding scheme for Fogera cattle breed that will be used as a guide for other Ethiopian indigenous cattle breed. Two types of data, on-farm and on-station, were used; the on-farm data was collected from three districts, namely, Fogera, Dera, and Bahir Dar Zuria; those are expected as the home of the breed. A total of 150 farmers, which are knowledgeable and having at least one cattle of Fogera phenotype in their herd, were purposively selected and interviewed. Additionally, farmer’s focus group discussion (FGD was conducted to capture the historical background, population, and distribution of the breed. SPSS (version 16 and index method was used to analyze the quantitative and scoring data’s, respectively. A meeting at national and regional level was also conducted to evaluate the existing conservation strategy and to identify the major stakeholders for the strategy. The main reasons to conserve Fogera breed are due to presence of interrelated constraints, presence of unique traits of the breed, better attitude of farmers, and decreasing population trend of the breed. Community-based in situ conservation strategy, to ensure the participation of the community, was designed for the breed. With the conservation strategy, related activities like feed development, animal health interventions, market linkage, and development of cooperatives will be implemented to improve the working environment. The stakeholders that are identified as an actor in the strategy should realize their honest participation for the sustainability of conservation and improvement of the breed.

    Smoking surveys among physicians have proved useful in highlighting the importance of physicians as healthy life style exemplars and role models in tobacco control and smoking cessation. The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014. Three cross-sectional postal surveys using a self-administered questionnaire were carried out among all practising physicians in Estonia. The number of physicians participating in this study was 3786 in 1982, 2735 in 2002, and 2902 in 2014. Data analysis involved calculating the age-standardized prevalences of smoking, prevalences of smoking by age group and mean age of smoking initiation. A non-parametric test for trend was used to assess significant changes in smoking over time. Age-standardized prevalence of current smoking among men was 39.7% in 1982, 20.9% in 2002, and 14.3% in 2014 and among women 12.2%, 8.0%, and 5.2%, respectively (p smoking among men and women was in age groups under 35 (from 55.2% to 16.7% and from 16.7% to 2.8%, respectively) and 35-44 (from 47.1% to 8.3% and from 19.5% to 5.1%, respectively) (p smoking initiation decreased from 20.4 to 19.3 among men and from 24.5 to 20.4 among women over the study period. In 1982-2014, smoking prevalence among Estonian physicians declined substantially. This may influence the willingness of society to recognize the health consequences of smoking which could give a support to the decline of the smoking epidemic in the country. Differences between smoking among male and female physicians persisted over the study period, but mean age of smoking initiation decreased. A further decline in smoking among Estonian physicians should be encouraged by special efforts targeted at physicians.

    Full Text Available The article investigates lexical collocations encountered in English as a Foreign Language (EFL instruction in Estonian upper secondary schools. This is achieved through a statistical analysis of collocations featuring in three coursebooks where the collocations found are analysed in terms of their type, frequency and usefulness index by studying them through an online language corpus (Collins Wordbanks Online. The coursebooks are systematically compared and contrasted relying upon the data gathered. The results of the study reveal that the frequency and range of lexical collocations in a language corpus have not been regarded as an essential criterion for their selection and practice by any of the coursebook authors under discussion.

    In 1985-1988, 2287 farm animals (cattle, camels, sheep, goats, horses, donkeys, dogs and rabbits) suspected of carrying parasitic mites were examined at 58 farms throughout Libya. Mites were identified on 1303 of these animals. The commonest parasites on cattle were Psoroptes and Chorioptes, on camels and sheep were Sarcoptes and Psoroptes, and on goats were Sarcoptes and Demodex. Infested horses carrier Psoroptes or Chorioptes, and one donkey carried Sarcoptes. Otodectes was common on dogs, but Sarcoptes was rare and no Demodex were seen. Rabbits often had psoroptic ear mange or sarcoptic body mange. Dermanyssus gallinae and Ornithonyssus bursa were seen on chickens, but no mites were found on pigeons, ducks or turkeys.

    Full Text Available Background: Leptospirosis is an emerging zoonosis and its occurrence has been reported to be rising globally. The environment plays an important role in the survival of Leptospira and determines the risk of infection. Those who were exposed to and had contact with contaminated environment through their occupational, recreational and other activities can be infected with the organism. Objective: To determine the seroprevalence of leptospirosis among cattle farmers, prevalence of pathogenic Leptospira, and the workplace environmental risk factors for leptospirosis among cattle farmers in northeastern Malaysia. Methods: A cross-sectional study involving 120 cattle farmers was conducted. The participants answered an interviewer-guided questionnaire that consisted of sociodemographic and workplace environment characteristics questionnaire, before having their blood sample taken for microscopic agglutination test (MAT. Seropositivity was determined using a cut-off titer of ≥1:100. 248 environmental samples were also collected from the cattle farms for polymerase chain reaction (PCR. Results: The overall seroprevalence of leptospiral antibodies was 72.5% (95% CI 63.5% to 80.1% and the prevalence of pathogenic Leptospira in the cattle farms environment was 12.1% (95% CI 8.4% to 17.0%. The independent factors associated with seropositivity of leptospirosis among cattle farmers were positive pathogenic Leptospira in the environment (Adj OR 5.90, 95% CI 1.34 to 26.01 and presence of garbage dumping in the farm (Adj OR 2.40, 95% CI 1.02 to 5.65. Conclusion: Preventing leptospirosis incidence among cattle farmers necessitates changes in work environment. Identifying modifiable factors may also contribute to the reduction of infection.

    Escherichia coli O157 are zoonotic bacteria for which cattle are an important reservoir. Prevalence estimates for E. coli O157 in British cattle for human consumption are over 10 years old. A new baseline is needed to inform current human health risk. The British E. coli O157 in Cattle Study (BECS) ran between September 2014 and November 2015 on 270 farms across Scotland and England & Wales. This is the first study to be conducted contemporaneously across Great Britain, thus enabling comparison between Scotland and England & Wales. Herd-level prevalence estimates for E. coli O157 did not differ significantly for Scotland (0·236, 95% CI 0·166-0·325) and England & Wales (0·213, 95% CI 0·156-0·283) (P = 0·65). The majority of isolates were verocytotoxin positive. A higher proportion of samples from Scotland were in the super-shedder category, though there was no difference between the surveys in the likelihood of a positive farm having at least one super-shedder sample. E. coli O157 continues to be common in British beef cattle, reaffirming public health policy that contact with cattle and their environments is a potential infection source.

    Infections with Babesia bovis, Babesia bigemina, Theileria species and Anaplasma marginale are endemic in Kenya yet there is a lack of adequate information on their genotypes. This study established the genetic diversities of the above tick-borne hemoparasites infecting cattle in Kenya. Nested PCR and sequencing were used to determine the prevalence and genetic diversity of the above parasites in 192 cattle blood samples collected from Ngong and Machakos farms. B. bovis spherical body protein 4, B. bigemina rhoptry-associated protein 1a, A. marginale major surface protein 5, Theileria spp. 18S rRNA, T. parva p104 and T. orientalis major piroplasm surface protein were used as the marker genes. B. bovis, B. bigemina, T. parva, T. velifera, T. taurotragi, T. mutans and A. marginale were prevalent in both farms, whereas T. ovis, Theileria sp. (buffalo) and T. orientalis were found only in Ngong farm. Co-infections were observed in more than 50 % of positive samples in both farms. Babesia parasites and A. marginale sequences were highly conserved while T. parva and T. orientalis were polymorphic. Cattle-derived T. parva was detected in Machakos farm. However, cattle and buffalo-derived Theileria were detected in Ngong farm suggesting interactions between cattle and wild buffaloes. Generally, the pathogens detected in Kenya were genetically related to the other African isolates but different from the isolates in other continents. The current findings reaffirm the endemicity and co-infection of cattle with tick-borne hemoparasites, and the role of wildlife in pathogens transmission and population genetics in Kenya.

    Full Text Available Abstract Background Infection with Coxiella burnetii, the cause of Q-fever, has never been detected in Norwegian animals. Recognising the increasing prevalence of the infection in neighbouring countries, the aim of the study was to perform a survey of Norwegian farmed ruminants for the prevalence of C. burnetii infection. Results Milk and blood samples from more than 3450 Norwegian dairy cattle herds, 55 beef cattle herds, 348 dairy goat herds and 118 sheep flocks were serologically examined for antibodies against C. burnetii. All samples were negative for antibodies against C. burnetii. The estimated prevalences of infected herds were 0 (95% confidence interval: 0% - 0.12%, 0 (0% - 12%, 0 (0% - 1.2% and 0 (0% - 10% for dairy cattle herds, beef cattle herds, goat herds and sheep flocks, respectively. Conclusions The study indicates that the prevalence of C. burnetii infection in farmed Norwegian ruminants is low, and it cannot be excluded that Norway is free of the infection. It would be beneficial if Norway was able to maintain the current situation. Therefore, preventive measures should be continued.

    Cattle farming can promote diarrheal disease transmission through waste, effluents or cattle fecal matter. The study aims to characterize the diarrheagenic Escherichia coli (DEC) isolated from cattle feces, manure in the composting process and slurry, collected from four cattle markets in Ouagadougou. A total of 585 samples (340 cattle feces, 200 slurries and 45 manures in the composting process) were collected from the four cattle markets between May 2015 and May 2016. A multiplex Polymerase Chain Reaction (PCR), namely 16-plex PCR, was used to screen simultaneously the virulence genes specific for shiga toxin-producing E. coli (STEC), enteropathogenic E. coli (EPEC), enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC) and enteroaggregative E. coli (EAEC). DEC was detected in 10.76% of samples. ETEC was the most prevalent (9.91%). STEC and EAEC have been observed with the same rate (0.51%). ETEC were detected in 12.64% of cattle feces, in 6.66% of manure in the composting process and in 5% of slurry. STEC were detected in 0.58% of cattle feces and in 2.22% of manure in the composting process. EAEC was detected only in 1% of slurry and in 2.22% of manure in the composting process. ETEC strains were identified based on estIa gene and/or estIb gene and/or elt gene amplification. Of the 58 ETEC, 10.34% contained astA , 17.24% contained elt , 3.44% contained estIa and 79.31% contained estIb . The two positive EAEC strains contained only the aggR gene, and the third was positive only for the pic gene. The results show that effluent from cattle markets could contribute to the spreading of DEC in the environment in Burkina Faso.

    2012-05-01

    Domestic animals, including ruminants, can synthesize vitamin C (VC) in their liver; as such, the dietary requirement for VC has not been confirmed in these animals. The adequacy of VC has been evaluated by quantifying VC levels in plasma, but the reported values in bovine plasma have been widely variable. Plasma VC concentration is decreased by heat stress, hepatic lesions, fattening, and infectious diseases such as mastitis in cattle. Therefore, VC supplementation is potentially beneficial for cattle with low plasma VC concentration. This review discusses the methods for determination of plasma VC concentration in cattle, VC nutrition, and the efficacy of VC supplementation in calves, dairy cattle, and beef cattle. Additionally I propose a reference range for plasma VC concentration in Japanese Black cattle.

Texts dealing with prison camps could appear in print only outside the Soviet Union; the way Estonians saw these historical events and hellish experiences were depicted mostly in exile novels. Most notable are the novels by Arved Viirlaid (b. 1922, e.g., Kes tappis Eerik Hormi? (Who Killed Eerik Horm? (1974, Surnud ei loe (The Dead do not Read (1975, Vaim ja ahelad (Mind and Chains (1961. Estonian prison camp novels can be seen as “the literature of testimony”, to use the term by Leona Toker. Dramatic historical events are written down to record the events and to show the inhumane nature of Soviet society. These records of the dramatic past follow certain patterns and create certain self- and hetero-images. A prison camp is a closed territory within a closed territory; prison camps can be seen as small models of Soviet society. Prison camp novels give a detailed view of the environment of the prison camp, its inhabitants and activities. Two central aspects are labour and food; the life of the prisoner whirls around these. The most important thing is to survive, which often leads to moral decline, e.g., stealing, cheating. However, there are lines Estonians do not cross, e.g., cannibalism or homosexual relationships with superiors. Estonians are always depicted as political prisoners (not common criminals and heterosexuals, while Russians are portrayed mainly as criminals and often also as homosexuals. Another important component of the image of the Estonians is their enterprising spirit and ability to manage even under very difficult conditions. Therefore, several oppositions can be identified, e

    To study the long-term mental health consequences of the 1986 Chernobyl nuclear accident among cleanup workers from Estonia. In 2010, 614 Estonian Chernobyl cleanup workers and 706 geographically and age-matched population-based controls completed a mail survey that included self-rated health, the Posttraumatic Stress Disorder Checklist (PCL), alcohol symptoms (AUDIT), and scales measuring depressive, anxiety, agoraphobia, fatigue, insomnia, and somatization symptoms. Respondents were dichotomized into high (top quartile) and low symptom groups on each measure. Logistic regression analysis detected significant differences between cleanup workers and controls on all measures even after adjustment for ethnicity, education, marital status, and employment status. The strongest difference was found for somatization, with cleanup workers being three times more likely than controls to score in the top quartile (OR = 3.28, 95% CI 2.39-4.52), whereas for alcohol problems the difference was half as large (OR = 1.52, 95% CI 1.16-1.99). Among cleanup workers, arrival at Chernobyl in 1986 (vs. later) was associated with sleep problems, somatization, and symptoms of agoraphobia. The toll of cleanup work was evident 24 years after the Chernobyl accident among Estonian cleanup workers indicating the need for focused mental health interventions.

    One purpose of this project was the establishment of a radon monitoring programme inside the state environmental monitoring programme. Another purpose was to investigate regions, expected to have high radon levels indoors. A new method for the long-term measurement of indoor radon was established and the staff for these measurements was trained. The results of the measurement can be used by Estonian decision-makers to work out rules and standards. There is no legislative act in the field of radiation in Estonian at this time. To summarize the results of the measurements we can say that indoor radon concentrations vary by region. The radon investigations must be continued to identify the risk areas and types of housing construction. The results of the state radon monitoring are provided to the municipalities, who advice the owners of planned new houses to select the right construction for the house. A new project will follow with an investigation of radon in randomly selected dwellings, training and equipment for radon measurement in soil, and general advice with regard to radon, as well as assistance in preparing information about radon. 7 refs, 5 figs

    Lameness in dairy cattle remains a significant welfare concern for the UK dairy industry. Farms were recruited into a 3-yr study evaluating novel intervention approaches designed to encourage farmers to implement husbandry changes targeted toward reducing lameness. All farms completing the study were visited at least annually and received either monitoring only (MO, n=72) or monitoring and additional support (MS, n = 117) from the research team. The additional support included traditional technical advice on farm-specific solutions, facilitation techniques to encourage farmer participation, and application of social marketing principles to promote implementation of change. Lameness prevalence was lower in the MO (27.0 ± 1.94 SEM) and MS (21.4 ± 1.28) farms at the final visit compared with the same MO (38.9 ± 2.06) and MS (33.3 ± 1.76) farms on the initial visit. After accounting for initial lameness, intervention group status, and year of visit within a multilevel model, we observed an interaction between year and provision of support, with the reduction in lameness over time being greater in the MS group compared with the MO group. Farms in the MS group made a greater number of changes to their husbandry practices over the duration of the project (8.2 ± 0.39) compared with those farms in the MO group (6.5 ± 0.54). Because the lameness prevalence was lower in the MS group than the MO group at the start of the study, the contribution of the additional support was difficult to define. Lameness can be reduced on UK dairy farms although further work is needed to identify the optimum approaches. Copyright © 2012 American Dairy Science Association. Published by Elsevier Inc.

    Full Text Available Beef consumption has significantly increased in the last fifty years as a response to the increase in population size, whereas the sustainability of production systems has begun to be questioned. Because the residues left in the animal feed additives used in conventional food production constitute major health problems in consumers. Therefore, an interest in organic farming methods based on natural grazing and feed production without the use of chemicals is increasing. One of the most important examples of organic beef production in Turkey is the project carried out in the villages of Ayvacık district in Çanakkale. This region has an ecological structure which does not allow an extensive production of culture cattle. The most important advantages of the Turkish grey cattle living in the pastures in the region covered with bushes are that they have less needs of shelter, they do not need supplementary feeding throughout the year and labor costs for their production for beef are low. Breeders in this region maintained a market price for their products by shifting to organic system and thus allowed the sustainable production of the Turkish grey cattle. In this study, Ayvacık Organic Beef Production Project which sets an example for the sustainability of Turkish grey cattle production by featuring its surplus values was evaluated.

    Full Text Available This article aims to give an overview of literary instruction in schools of the russification era at the beginning of the 20th century in Estonia; this was likewise the curriculum of literary study offered to the generation of educated youth which included the Young Estonians. Based on official documents, archival materials, and memoirs, and through analyses of anthologies, literary histories, and teaching methods in use at the time, we attempt to reconstruct the outlines of literary reading and requirements for students in various types of schools. When, as a result of school reform, Russian became the language of instruction; lessons in Russian became central in the curriculum, alongside the word of God; selections from Russian literature were read in the original language. In the lower grades, teaching was by the so-called ”natural method”, intended to guarantee swift achievement of fluency in ”living Russian language”; this was later replaced by systematic textual analysis, which distinguished between belles lettres and other types of texts. However, the study of literature was always subordinated to the goals of language instruction. In institutions of secondary education, study of Russian literature was separate from language instruction. Indeed, Russian literature was the only literature systematically studied in high schools (though one must keep in mind that not all schools completely followed the official program. Private schools were especially noticeable for their greater freedom, though all of them had to take general curriculum directives into account. Reading of literary texts connected with other languages thus had to remain almost purely illustrative. In view of the above, in the upper grades of elementary school and high school, students obtained a thorough introduction to the Russian classics. According to the official school curriculum, Russian literary history ended with Nikolai Gogol. Attempts were made to ignore

    Full Text Available This paper analyses representations of the ‘core Soviet era’ (1945-1985 in Estonian post-Soviet history textbooks (1989-2016. Attitudes towards the Soviet system have been a rich resource for identity building, and hence a powerful political tool across the whole of the post-Soviet block. Based on an analysis of sections about the Soviet era in Estonia in 21 textbooks, the paper takes a look at how textbooks reflect broader processes of social meaning making, identity building and othering after a profound social and political turn. In 1989 and during the early 1990s, perspectives and narratives in Estonian history textbooks were closely related to social memory and national politics, enacting a specific social representation of the Soviet era that dominated the Estonian-speaking public space during the 1990s. The Soviet era, Russia and local Russians became the main Others for Estonia and Estonians. Over time, public discourse has diversified. The national curriculum and textbooks, however, still maintain the canon that formed in 1990s and thus reflect earlier sentiments. Apart from the increasing salience of Soviet-era daily life in more recent textbooks, the thematic choices and emphases have changed little since the 1990s. Therefore, even if the style of writing has ‘cooled down’, issues of identity preservation, resistance and accommodation, together with a saliently negative representation of wrongdoings by the Soviet system, still prevail. On the one hand, this testifies to the resilience of an established tradition in the textbook genre in general. On the other hand, it reflects the dominance of an ethnocentric tradition in Estonian history textbook writing. The paper discusses the implications of these findings for interethnic relations in Estonia.

    Full Text Available Poverty alleviation and environmental preservation are very important issues to many governments. Alley farming is beneficial to the environment because it conserves soil and sustains yields over time. Specifically, alley farming reduces soil erosion, which is a major problem in Thailand. Alley farming was conducted on a farmer’s field at Khaokwan Thong, a village in Uthaithani Province, Northern Thailand. We did a two-by-two factorial with and without alley farming, and with and without fertilizer. From this study, we observed that the two species used, Leucaena leucocephala and Acacia auriculiformis, grow well in Thailand, and that alley farming is suitable for Thailand. Few Thai farmers have heard about alley farming. However, it is nevertheless useful to know that there is potential for alley farming in Thailand using the two species. These plants, based upon the diameter and height measurements provided, grew well.

  6. Summer Farms in Switzerland: Profitability and Public Financial Support

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Summer farms are seasonal enterprises in high-elevation mountain regions, established for and highly specialized in grazing ruminants. This article synthesizes studies by the Swiss AlpFUTUR research program on the profitability of and public financial support for summer farms. It highlights current challenges of Swiss pastoralism and makes recommendations for future reforms. Profitability hinges on the size of the summer farms as well as on their ability to create value added. Particularly for smaller summer farms, key value-added strategies appear to be innovative cheese production and effective direct marketing. Public financial support is substantial, and the underlying agri-environmental scheme is relatively sophisticated. Eligibility for public support is based on both action-oriented and results-oriented criteria. Direct payments consider not only the number of livestock but also the duration of their presence on the summer pastures. For each summer farm, a stocking target is defined based on the pasture's carrying capacity. However, this target does not take into account the wide variation in forage needs between different meat and milk production systems. During the last decade, there has been a decline in the number of cattle sent to summer farms. Understocking is widespread, and the abandonment of marginal pastures has increased, resulting in scrub encroachment. The remaining cattle tend to be concentrated on more productive surfaces to reduce management costs; this causes overgrazing. More attention should therefore be given to the accurate enforcement of agri-environmental standards and to regional-level agreement on which surfaces should be abandoned. Supporting traditional pastoral practices remains an explicit objective of Swiss agricultural policy. Recently introduced agri-environmental payment schemes promoting biodiversity conservation can complement the summer farm subsidies. However, implementation costs are likely to

    Livestock production is a major sector of the Ugandan economy. Ugandan ruminant livestock (principally cattle and goats) are susceptible to hemoparasites that can cause serious clinical disease and production losses. Kibale National Park, in western Uganda, is a protected forest ecosystem surrounded by small-scale farms where cattle and goats are raised. We conducted a cross-sectional study of cattle and goats in this area and diagnosed hemoparasite infections by microscopy. We collected data on animal characteristics and management practices to assess risk factors associated with infection. We studied 186 cattle and 317 goats from 20 villages, including 16 villages directly adjacent to Kibale and 4 villages ≥3 km from the park boundary. Hemoparasites detected in cattle and goats were of the genera Theileria, Anaplasma, and Trypanosoma with a prevalence of 15.1%, 1.6%, and 4.3% respectively in cattle, and 10%, 6.0%, and 0.0%, respectively in goats. Trypanosomes infected approximately 8% of cattle in villages bordering Kibale but were never detected in cattle in "control" villages ≥3 km from the park. Trypanosomes were approximately 7 times more likely to infect animals in households that did not provide veterinary care to their animals than in households that provided routine veterinary care. Within cattle, Theileria infections were approximately 7 times more likely to occur in cross-bred cattle than in indigenous pure breeds. Anaplasma infections were approximately 3.5 times more likely to occur in cattle than in goats (no goats were diagnosed with Trypanosoma infection). These data suggest that proximity to the park, provision of veterinary care, and breed are significant risk factors for hemoparasites in this population of ruminants, and that, in general, cattle are more susceptible than goats.

    This study aimed to analyze the financial impact of foot-and-mouth disease (FMD) outbreaks in cattle at the farm-level and the benefit-cost ratio (BCR) of biannual vaccination strategy to prevent and eradicate FMD for cattle in South Vietnam. Production data were collected from 49 small-scale dairy farms, 15 large-scale dairy farms, and 249 beef farms of Long An and Tay Ninh province using a questionaire. Financial data of FMD impacts were collected using participatory tools in 37 villages of Long An province. The net present value, i.e., the difference between the benefits (additional revenue and saved costs) and costs (additional costs and revenue foregone), of FMD vaccination in large-scale dairy farms was 2.8 times higher than in small-scale dairy farms and 20 times higher than in beef farms. The BCR of FMD vaccination over 1 year in large-scale dairy farms, small-scale dairy farms, and beef farms were 11.6 [95% confidence interval (95% CI) 6.42-16.45], 9.93 (95% CI 3.45-16.47), and 3.02 (95% CI 0.76-7.19), respectively. The sensitivity analysis showed that varying the vaccination cost had more effect on the BCR of cattle vaccination than varying the market price. This benefit-cost analysis of biannual vaccination strategy showed that investment in FMD prevention can be financially profitable, and therefore sustainable, for dairy farmers. For beef cattle, it is less certain that vaccination is profitable. Additional benefit-cost analysis study of vaccination strategies at the national-level would be required to evaluate and adapt the national strategy to achieve eradication of this disease in Vietnam.

    The present study aimed to compare mitochondrial diversity among Balkan Neolithic/Chalcolithic cattle and present day Shorthorn Rhodopean cattle (Busha) to throw a new insight into European cattle domestication. The results showed that both ancient- and present-day samples belonged to the macrohaplogroup T. From the 28 sequences (8 ancient and 20 modern), the T1 and T2 haplogroup represent about 3.6% (1/28; 1/28). The T3 haplogroup was with the highest frequency - 57% (16/28). Based on the SNPs on 16057A and 16133C, the new T6 haplogroup was proposed. This haplogroup represents 75% from the ancient and 20% from the present day Bulgarian brachicerous cattle population. The survey in GenBank data base did not find a similar motif, except for the recent Serbian Busha cattle. Overall, these results showed that: (i) The newly named T6 haplogroup is Balkan specific; (ii) The T6 haplogroup survives in present day Bulgarian rhodopean cattle; (iii) The Balkan brachicerous cattle is the oldest European cattle breed.

We use survey data from a sample of 356 farmers based on multistage random sampling. Factor analysis is employed to classify scores of risk and management strategies, and multiple...... utilization were perceived as the most important strategies for managing risks. Livestock disease and labor shortage were perceived as less of a risk by farmers who adopted the practice of zero grazing compared to other farmers, pointing to the potential of this practice for risk reduction. We find strong...... evidence that farmers engage in multiple risk management practices in order to reduce losses from cattle morbidity and mortality. The results suggest that government strategies that aim at reducing farmers’ risk need to be tailored to specific farm and farmer characteristics. Findings from this study have...

    Despite the importance of the cattle industry in Malaysia, there are very few studies of the diversity and public health significance of bovine cryptosporidiosis in this country. In the present study, we used a PCR-based approach to detect and genetically characterize Cryptosporidium DNA in faecal samples from a cohort of 215 asymptomatic cattle (of different ages) from six farms from five states of Peninsular Malaysia. Cattle on four of the six farms were test-positive for Cryptosporidium, with an overall prevalence of 3.2%. Cryptosporidium bovis and Cryptosporidium ryanae were detected in two (0.9%) and five (2.3%) samples tested; this low prevalence likely relates to the age of the cattle tested, as most (73%) of the samples tested originated from cattle that were ≥2 years of age. Future studies should investigate the zoonotic potential of Cryptosporidium in pre-weaned and weaned calves in rural communities of Malaysia. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The world's population will reach 10.4 billion in 2067, with 81% residing in Africa or Asia. Arable land available for food production will decrease to 0.15 ha per person. Temperature will increase in tropical and temperate zones, especially in the Northern Hemisphere, and this will push growing seasons and dairy farming away from arid areas and into more northern latitudes. Dairy consumption will increase because it provides essential nutrients more efficiently than many other agricultural systems. Dairy farming will become modernized in developing countries and milk production per cow will increase, doubling in countries with advanced dairying systems. Profitability of dairy farms will be the key to their sustainability. Genetic improvements will include emphasis on the coding genome and associated noncoding epigenome of cattle, and on microbiomes of dairy cattle and farmsteads. Farm sizes will increase and there will be greater lateral integration of housing and management of dairy cattle of different ages and production stages. Integrated sensors, robotics, and automation will replace much of the manual labor on farms. Managing the epigenome and microbiome will become part of routine herd management. Innovations in dairy facilities will improve the health of cows and permit expression of natural behaviors. Herds will be viewed as superorganisms, and studies of herds as observational units will lead to improvements in productivity, health, and well-being of dairy cattle, and improve the agroecology and sustainability of dairy farms. Dairy farmers in 2067 will meet the world's needs for essential nutrients by adopting technologies and practices that provide improved cow health and longevity, profitable dairy farms, and sustainable agriculture.

    Schmallenberg virus (SBV) is a recently identified member of the genus Orthobunyavirus of the family Bunyaviridae. It is an arbovirus transmitted by different members of Culicoides spp of biting midges. The virus is more recognized for its effect on reproductive disorders in ruminants characterised by abortion, stillbirth and birth of congenitally defective newborns with hydranencephaly-arthrogryposis syndrome. The current study was undertaken with the objectives of exploring the presence of SBV exposure and identification of factors affecting its distribution among dairy cattle in Ethiopia. A cross-sectional study was conducted on 1379 dairy cattle sampled from 149 dairy herds in central, southern and western Ethiopia during September 2011 to May 2012. Serum samples were examined using competitive enzyme linked immunosorbent assay (cELISA). Data on hypothesised risk factors were collected from farm records where available and semi-structured questionnaire-based interview. The apparent seroprevalence of exposure to SBV was 56.6% (95% confidence interval (CI): 53.9-59.3). True prevalence adjusted for sensitivity and specificity of the cELISA kit used was 58.3% (95% CI 55.7-60.9). Among the sampled herds, 82.6% (95% CI: 75.5-88.3) had at least one seropositive animal. Seropositive cattle were found in all of the 15 conurbations studied. Adult dairy cows [odds ratio (OR)=1.6] were more commonly affected than young heifers. Dairy cattle kept in commercial (OR=1.6) and breeding farms (OR=3.5) and Midland agroecology (OR=2.5) showed statistically significant seroconversion than cattle kept under small-holder dairy farms and Highland agroecology respectively (p<0.05). Reproductive disorders including abortion, retention of the fetal membranes, and metritis were associated with serostatus of SBV. In conclusion, the seroprevalence of SBV is high and widely distributed in the studied parts of Ethiopia. This being the first study of its kind on SBV in Ethiopia, further

    2007-05-01

    Full Text Available This paper presents the importance of the crop structure as a tool to maximize efficiency in the conceiving of the green forage supply scheme in a dairy farm. Several apects are necessary to consider for proper green forage utilization by the cattle, as follows: climatic conditions, proper field operations for each crop, optimal harvest date, and farm technical and economical resources. With a high degree of succulence, green forage and derived products (silage, haylage, present addvantages as compared to hay, having superior indices of nutritive value and palatability. A green forage supply scheme was applied on an area of 188 ha taking into account dairy cattle biological traits. Crop structure was as follows: forage maize, Sudan grass, Italian ryegrass, new lucern and old lucerne, and orchardgrass. Insuring the required superior green forage for the dairy cattle according to forage rations, represents one of the main techniques to maximize milk production and to minimize milk production cost.

    Full Text Available The study focused on the prevalence of Staphylococcus aureus and resistant strains in livestock. In this study, 114 different samples from three cattle farms (84 from two farms of dairy cows and 30 from one farm of suckler cows, 132 samples from one sheep farm, 120 samples from one goat farm, and 82 samples from three pig farms were examined. Strains identified as Staphylococcus aureus were further analysed by the polymerase chain reaction method for detection of the mecA gene and for confirmation of the sequence type 398. Positive incidence of Staphylococcus aureus was confirmed in farms of suckler cows, sheep, goats and pigs. The incidence of methicilin-resistant Staphylococcus aureus was confirmed at a goat farm, with all strains belonging to the sequence type 398. Repetitive element palindromic-polymerase chain reaction analysis was performed to compare the relatedness of selected human and animal S. aureus strains at the goat and sheep farms. The obtained data from repetitive element-polymerase chain reaction analysis showed significant clonal similarity among the tested isolates and indicated the possibility of mutual transmission between animals or animal and human and possible transfer in the food chain.

    Full Text Available The governmental initiative called the Compatriots Programme, which supports language tuition in Estonian schools and societies abroad, reveals an increased interest in developing intergenerational language transmission in the growing Estonian diaspora. This transnational language political activity signals a new era in language policy, where nation states are increasingly decentralized by migration. The evaluation of the program furthermore reveals that organizing such schools requires a willingness to take language political agency, typically conducted by well-educated and well-integrated resourceful transnational multilingual parents. The present article outlines the results of an ethnographic study of the process of establishing the Estonian School in Copenhagen. This step has demanded a change in the mindset still prevailing in Estonia that language political activities, such as planning language acquisition, are solely the responsibility of the state. Since the prevailing language ideology in Denmark is not favorable towards multilingualism in migrant languages, intergenerational language transmission furthermore presupposes a feeling of ownership of the language and high language self-esteem.

    Full Text Available Weed seeds may maintain their viability when passing through the digestive tract of cattle and can be therefore dispersed by animal movement or the application of manure. Whether different cattle types of the same species can cause differential weed seed fate is largely unknown to us particularly under non-grazed systems similar to Holstein-Friesian dairy farming. We investigated the effect on the seed survival of four weed species in the digestive tracts of four groups of Holstein cattle: lactating cows, feedlot male calves, dry cows and growing heifers. The weed species used were Cuscuta campestris, Polygonum aviculare, Rumex crispus and Sorghum halepense. Cattle excretion was sampled for recovery and viability of seeds at four 24 hourly intervals after seed intake. The highest seed recovery occurred two days after seed intake in all cattle groups. Averaged over weed species, dry and lactating cows had the lowest and highest seed recovery of 36.4% and 74.4% respectively. No significant differences were observed in seed recovery of the four weed species when their seeds were fed to dry cows. Based on a power model fitted to seed viability data, the estimated time to 50% viability loss after seed intake, over all cattle groups ranged from 65 h (R. crispus to 76 h (P. aviculare. Recovered seeds from the dung of feedlot male calves showed the highest mortality among cattle groups. Significant correlation was found between seed viability and ruminal pH (r = 0.86; P<0.05. This study shows that management programs aiming to minimize weed infestation caused by livestock should account for the variation amongst cattle groups in seed persistence. Our findings can be used as a guideline for evaluating the potential risk of the spread of weeds via the application of cattle manure.

    2012-09-01

    Full Text Available Resource allocation is a point of concern in small to large farms and is generally argued that small farmers in developing countries are “poor but efficient”, trying to allocate the limited resources to unlimited desires efficiently in the given production system in the light of their life-long experiences. The issue of market orientation in cattle fattening is basically challenged with the risks and uncertainties in the production and the market. Data were collected from 112 purposively selected fattening operator farmers from 3 districts and 6 peasant associations to see the risks. The data were analyzed through both descriptive and econometric statistical tools using STATA. Only about 13% of the respondents have participated in the farm business with own capital and the vast majority borrowed from Amhara Credit and Saving Association (ACSI through their cooperatives. It is found that production risks are limited while economic and market related risks play vital role in the farm operation. Duration of stay of the cattle, land holding of the household, distance to the development agent’s office and age of the household head increase the risk averse nature of the household and limit their participation in export market. In the other hand, frequency of fattening enhances the risk taking character of the households and their participation in the export of cattle. It is vital to enhance the institutional support from the public to enhance the gain from the fattening activity and market orientation of farming.

  12. Practical applications of trace minerals for dairy cattle.

    Overton, T R; Yasui, T

    2014-02-01

    Trace minerals have critical roles in the key interrelated systems of immune function, oxidative metabolism, and energy metabolism in ruminants. To date, the primary trace elements of interest in diets for dairy cattle have included Zn, Cu, Mn, and Se although data also support potentially important roles of Cr, Co, and Fe in diets. Trace minerals such as Zn, Cu, Mn, and Se are essential with classically defined roles as components of key antioxidant enzymes and proteins. Available evidence indicates that these trace minerals can modulate aspects of oxidative metabolism and immune function in dairy cattle, particularly during the transition period and early lactation. Chromium has been shown to influence both immune function and energy metabolism of cattle; dairy cows fed Cr during the transition period and early lactation have evidence of improved immune function, increased milk production, and decreased cytological endometritis. Factors that complicate trace mineral nutrition at the farm level include the existence of a large number of antagonisms affecting bioavailability of individual trace minerals and uncertainty in terms of requirements under all physiological and management conditions; therefore, determining the optimum level and source of trace minerals under each specific situation continues to be a challenge. Typical factorial approaches to determine requirements for dairy cattle do not account for nuances in biological function observed with supplementation with various forms and amounts of trace minerals. Trace mineral nutrition modulates production, health, and reproduction in cattle although both formal meta-analysis and informal survey of the literature reveal substantial heterogeneity of response in these outcome variables. The industry has largely moved away from oxide-based programs toward sulfate-based programs; however, some evidence favors shifting supplementation strategies further toward more bioavailable forms of inorganic and organic trace

  13. Estimating Phosphorus Loss at the Whole-Farm Scale with User-Friendly Models

    Phosphorus (P) loss from agricultural fields and delivery to surface waters persists as a water quality impairment issue. For dairy farms, P can be lost from cropland, pastures, barnyards, and open-air cattle lots; and all these sources must be evaluated to determine which ones are a priority for P loss remediation. We used interview surveys to document land use, cattle herd characteristics, and manure management for four grazing-based dairy farms in Wisconsin, USA. We then used the APLE and Snap-Plus models to estimate annual P loss from all areas on these farms and determine their relative contribution to whole-farm P loss. At the whole-farm level, average annual P loss (kg ha-1) from grazing-based dairy farms was low (0.6 to 1.8 kg ha-1), generally because a significant portion of land was in permanently vegetated pastures or hay and had low erosion. However, there were areas on the farms that represented sources of significant P loss. For cropland, the greatest P loss was from areas with exposed soil, typically for corn production, and especially on steeper sloping land. The farm areas with the greatest P loss had concentrated animal housing, including barnyards, and over-wintering and young-stock lots. These areas can represent from about 5% to almost 30% of total farm P loss, depending on lot management and P loss from other land uses. Our project builds on research to show that producer surveys can provide reliable management information to assess whole-farm P loss. It also shows that we can use models like RUSLE2, Snap-Plus, and APLE to rapidly, reliably, and quantitatively estimate P loss in runoff from all areas on a dairy farm and identify areas in greatest need of alternative management to reduce P loss.

  14. Whole-word frequency and inflectional paradigm size facilitate Estonian case-inflected noun processing.

    Estonian is a morphologically rich Finno-Ugric language with nominal paradigms that have at least 28 different inflected forms but sometimes more than 40. For languages with rich inflection, it has been argued that whole-word frequency, as a diagnostic of whole-word representations, should not be predictive for lexical processing. We report a lexical decision experiment, showing that response latencies decrease both with frequency of the inflected form and its inflectional paradigm size. Inflectional paradigm size was also predictive of semantic categorization, indicating it is a semantic effect, similar to the morphological family size effect. These findings fit well with the evidence for frequency effects of word n-grams in languages with little inflectional morphology, such as English. Apparently, the amount of information on word use in the mental lexicon is substantially larger than was previously thought. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available The laser-induced breakdown spectroscopy (LIBS combined with multivariate regression analysis of measured data were utilised for determination of the heating value and the chemical composition of pellets made from Estonian oil shale samples with different heating values. The study is the first where the oil shale heating value is determined on the basis of LIBS spectra. The method for selecting the optimal number of spectral lines for ordinary multivariate least squares regression model is presented. The correlation coefficient between the heating value predicted by the regression model, and that measured by calorimetric bomb, was R2=0.98. The standard deviation of prediction was 0.24 MJ/kg. Concentrations of oil shale components predicted by the regression model were compared with those measured by ordinary methods.

    Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

    Full Text Available The article investigates the selection and sequencing of the idioms encountered in two locally-produced and international coursebook series currently employed in Estonian basic schools. It is hypothesized that there exists a positive correlation between idioms’ difficulty and coursebooks’ language proficiency level. The hypothesis is tested through a statistical analysis of the idioms found which are categorized in terms of their analysability into three categories where category 1 includes analysable semi-literal idioms, category 2 comprises analysable semi-transparent idioms, and category 3 encompasses non-analysable opaque idioms, and then analysed through an online language corpus (British National Corpus. The results of the study reveal that the coursebook authors under discussion have disregarded idioms’ frequency as a criterion for selection or sequencing, whereas the factor utilized to some extent is the degree of analysability.

    Sõukand, Renata; Kalle, Raivo

    2011-05-17

    The aim of this paper is to compare the changes in the utilization of species from various hemeroby categories (indicating the degree of sensitivity of the plant to human impact) using historical data concerning the years 1888-1994. The authors digitised 8808 handwritten reports, reflecting local ethnopharmacological knowledge from 8 selected collections from the Estonian Folklore Archives of the Estonian Literary Museum. They were semi-quantitatively analyzed according to the sensitivity to human impact of 540 taxa that could possibly be related to the plant vernacular names given in the reports. Although in different periods of time the number of ethnopharmacologically used plants has changed, the proportion of plants utilized from each group has remained relatively same, consisting on average of: 23% anthropophytes, 42% apophytes, 32% hemeradiaphores and 3% hemerophobes. Comparison of the application of the most used plants revealed considerable changes of plant utilization, in which the varied use of the most popular anthropophytes increased and the applied scope of the most popular hemeradiaphores and hemerophobes decreased almost by twofold in one century. Case studies on seven taxa are presented, of them, use of Allium sativum L., Aesculus hippocastanum L. and Mentha xpiperita L. increased, whereas the use of Hordeum L., Orchidaceae, Paris quadrifolia L. and Briza media L. decreased greatly. This research contributes to the better understanding of the cognitive and human ecological concepts underlying the use of medicinal plants in Estonia. Strong increase in the ethnomedical utilization of plants depending on human influence, and a decrease in the use of taxa that do not prefer human activities indicates that, despite some of the population still have access to natural resources and diverse knowledge of the medical use of plants, the majority relies on a very narrow selection and a rather restricted herbal landscape.

    To determine the prevalence and diversity of Leptospira serogroups circulating in wildlife on farms in Ontario, we tested samples from 51 raccoons (Procyon lotor), seven skunks (Mephitis mephitis), four rats (Rattus norvegicus), and three opossums (Didelphis virginiana) that were trapped on 27 livestock (swine [Sus scrofa], cattle [Bos taurus]) farms in 2010. Seventeen of 51 raccoons (33%; 95% confidence interval [CI], 21-48%) sampled were positive for at least one Leptospira serogroup using the microscopic agglutination test. None of the other 14 animals had detectable Leptospira antibodies. On swine farms, 13 of 30 raccoons (43%; 95% CI, 27-61%) were antibody positive, and on cattle farms, four of 21 raccoons (19%; 95% CI, 8-40%) were positive. Leptospira antibody prevalence in raccoons did not differ between swine and cattle farms. Raccoons were positive to serovars representative of serogroups Grippotyphosa, Australis, Icterohaemorrhagiae, and Pomona and were negative to serovars of serogroups Autumnalis, Canicola, and Sejroe. The prevalence of Leptospira antibodies in raccoons in this study is similar to what has been reported previously; however, the diversity of serogroups was higher in this study than what has been reported in raccoons from an urban area of Ontario, Canada. Understanding the prevalence and distribution of Leptospira serogroups in wildlife in Ontario, Canada, is important for the development and maintenance of appropriate disease management strategies in humans, livestock, and companion animals.

    2008-06-01

    Neospora caninum is widely recognized as one of the most important abortifacients in cattle and causes substantial financial losses to bovine livestock production. This study aimed to calculate the losses caused by N. caninum on Swiss dairy farms and to evaluate the efficacy and profitability of the control strategies culling, not breeding replacements and chemotherapy of calves on farm level. Three different farm sizes with high, medium and low herd prevalences were defined. Epidemiological and financial models were used to simulate the effect of control strategies on the prevalence over time and to perform a cost-benefit analysis. The median annual losses on farm level ranged between CHF 3094.- (= Euro 1875; 60 dairy cattle, high prevalence) and CHF 134.- (= Euro 81; 15 dairy cattle, low prevalence). Culling of animals that had any abortion or a N. caninum abortion, or not breeding replacements from such animals, respectively, were neither effective nor profitable. Only the strategy "not breeding replacements from N. caninum seropositive cows" on farms with a high prevalence was financially attractive. The strategy "chemotherapy of calves" should be re-evaluated as soon as new data regarding the efficacy of treatment and a corresponding protocol have been scientifically validated.

    Full Text Available In the rural municipality of Paipa, Boyaca many families rely on cattle breeding to obtain from this activity, suficient income and resources to meet their basic needs, however little is known about the true role of this species in the nourishment safety of rural families in the municipality of Paipa in Boyacá, for that reason, this study aimed to analyze the importance of general breeding cattle in the nourishment safety of thirty peasant families in the municipality of Paipa, Boyacá and get to know the social and cultural roles that are generated by this livestock activity. The obtained result was that the cale are raised as a second choice in the pursuit of economic resources, after the birds. In cattle production an average of  five animals per farm are raised, the widely used breeds are the Normando, Holstein and crosses between them; milk production dominates with an average yield of 150 liters/week per family; income and costs production depend on the number of cattle raised, the gained income is used to purchase food for home, but savings are not encouraged; the consumption of dairy products is very low and beef cattle is not consumed within the household; animals management is in charge of all family members (both genders. In general, cattle farming make interesting economic contributions to the countryside families, but these revenues are used to purchase food of high nutritional value, also a2ecting the nourishment safety of the studied families.

    Osteogenesis imperfecta (OI) is a rare bone disorder. In 90% of cases, OI is caused by mutations in the COL1A1/2 genes, which code procollagen α1 and α2 chains. The main aim of the current research was to identify the mutational spectrum of COL1A1/2 genes in Estonian patients. The small population size of Estonia provides a unique chance to explore the collagen I mutational profile of 100% of OI families in the country. We performed mutational analysis of peripheral blood gDNA of 30 unrelated Estonian OI patients using Sanger sequencing of COL1A1 and COL1A2 genes, including all intron-exon junctions and 5'UTR and 3'UTR regions, to identify causative OI mutations. We identified COL1A1/2 mutations in 86.67% of patients (26/30). 76.92% of discovered mutations were located in the COL1A1 (n = 20) and 23.08% in the COL1A2 (n = 6) gene. Half of the COL1A1/2 mutations appeared to be novel. The percentage of quantitative COL1A1/2 mutations was 69.23%. Glycine substitution with serine was the most prevalent among missense mutations. All qualitative mutations were situated in the chain domain of pro-α1/2 chains. Our study shows that among the Estonian OI population, the range of collagen I mutations is quite high, which agrees with other described OI cohorts of Northern Europe. The Estonian OI cohort differs due to the high number of quantitative variants and simple missense variants, which are mostly Gly to Ser substitutions and do not extend the chain domain of COL1A1/2 products.

    and the volume of cattle imported from endemic regions. Conclusions Although the most likely source of bTB infections in Scotland was cattle previously imported from endemic regions, we found indirect evidence of transmission within Scottish cattle farms and cannot rule out the possibility of low level transmission between farms. Further investigation is needed to determine whether targeting herds with unconfirmed reactors and a history of importing cattle from high risk regions would benefit control efforts. PMID:24206865

    Full Text Available The purpose of the study was to explore differences between dairy cattle farmers in Bulgaria, according to certain factors. Information about the social characteristics of the farmers (educational level, gender, and age, and about the farm characteristics (number of cows in the main herd, average milk yield, and the rate of return on investment was collected. Sixty percent of the farmers were up to 50 years of age. Fifty percent of the farmers had had a secondary education and the rest had gained a university degree. The study found that only one of the 20 farmers was a woman. It was found that the group of farmers with a university degree had lower average age than the group of farmers with secondary school. There was no significant difference in the rate of return between the two groups of farms in terms of the effectiveness of the farm. The difference in the number of cows in the main herd was not significant too. The research identified a need for additional training for farmers in order to reduce their dependence on hired workers. It was found that farmers attend basic courses in the field of agriculture and livestock breeding in order to fill the gap between the existing levels of knowledge of farmers and the necessary skills for the effective management of dairy farms.

  11. How to Improve the Supportive Role of Estonian Innovation System toward Launching New Products by High Technology Companies?

    Full Text Available The purpose of the study is to evaluate how supportive is Estonian national innovation system toward the launching of new innovative products by high technology firms. The article intends to combine two broad areas of research – national innovation system approach and the different models of the new product launching. Based on the literature review and in-depth analysis of three case studies of Estonian high-tech company’s major barriers as well success factors of highly innovative product launches were identified. The barriers of the new product launching were linked with the systemic failures of the national innovation system. The most relevant failures of Estonian national innovation system inhibiting the new product development are capability and networking failures. The sources of innovation of high-technology firms are too narrow, linkages with domestic firms and higher education institutions as well with foreign firms are poorly developed. High-tech firms have also serious capacity problems due to the extremely weak support mechanism by national innovation system on the seed funding stage of product development and prototype building stage as well. Paper argues that resources needed for the innovation should not be looked too narrowly following linear innovation model approach. Instead interactive approach is needed, which combines capability building, network development, interactive learning with direct investments into fundamental research.

  12. Combating radiocesium contamination in farm animals

    1988-01-01

    Considerable amounts of radioactive fallout from the Chernobyl accident swept central parts of Norway, where especially native mountain areas but also some agricultural land were heavily contaminated. Parts of the heavily polluted areas are important in Norwegian animal production, being grazed by reindeer all year, and by sheep, goats and cattle in the summer. Cs-137 and Cs-134 appeared in feeds shortly after the accident and the levels increased throughout the summer. In this paper some of the results obtained in experiments with contaminated animals in Norway are reviewed. Experiments in connection with the use of uncontaminated feeds for decontamination of farm animals, the transfer of radioactivity to milk, and the use of cesiumbinders to reduce cesium contamination are described

  13. Tuberculosis in cattle: the results of the four-area project

    2005-11-01

    Full Text Available The four-area project was undertaken to further assess the impact of badger removal on the control of tuberculosis in cattle herds in Ireland. It was conducted between 1997 and 2002 in matched removal and reference areas in four counties, namely Cork, Donegal, Kilkenny and Monaghan, representing a wide range of Irish farming environments. In the removal areas, a proactive programme of badger removal was conducted, on two or three occasions each year, whereas in the reference areas, badger removal was entirely reactive following severe outbreaks of tuberculosis amongst cattle. A detailed statistical analysis of this study has already been presented by Griffin et al. 13; this paper presents further, mainly descriptive, findings from the study. In total, 2,360 badgers were captured in the removal areas of which 450 (19.5% were considered positive for tuberculosis and 258 badgers were captured in the reference areas, with 57 (26.1% positive for tuberculosis. The annual incidence of confirmed herd restrictions was lower in the removal area compared to the reference area in every year of the study period in each of the four counties. These empirical findings were consistent with the hazard ratios found by Griffin et al. 13. Further, the effect of proactive badger removal on cattle tuberculosis in the four-area project and in the earlier east-Offaly project, as measured using the number of reactors per 1,000 cattle tested, were very similar, providing compelling evidence of the role of badgers in the epidemiology of tuberculosis in Irish cattle herds. The validity of the four-area project was discussed in detail. Efforts to minimise badger-to-cattle transmission in Ireland must be undertaken in association with the current comprehensive control programme, which has effectively minimised opportunities for cattle-to-cattle transmission.

    2012-06-01

    Full Text Available The article discusses three Estonian translations of Daniel Defoe’s Robinson Crusoe into Estonian with the focus on the completeness of the translated texts and the characterisation given to these in paratextual information. While there are several translations and versions of the tex t available in E stonian that have either used a mediating language or do not proceed directly from Defoe’s novel, three editions explicitly list Defoe’s English-language Robinson Crusoe as their source text. These are Rudolf Sirge’s translation from 1950 and two editions translated by Valter Rummel that appeared in 1984 (reprinted in 2001 and 2007, respectively. The article sets out to discover the main differences between the three editions and the possible reasons that may have triggered their publication in Estonia at those particular times. In order to approach the issues, a general framework derived from descriptive translation studies is employed with an emphasis on Gideon Toury’s chrestomatic treatment of translation norms. Thus an attempt is made to detect the preliminary translational norms regarding translation policy, particularly the choice of texts to be translated, as well as the matricial norms that concern the fullness of the translated text and are part of operational norms manifested in the translator’s decisions which, in two of the cases at hand, may also have been decisions made by the editor or the censor. Rudolf Sirge’s translation appeared at a time when Estonia had fairly recently been incorporated into the Soviet Union and there was a lack of children’s literature ideologically appreciated by the regime. This may account for the packaging of the book as a work with a strong didactic bent, while its primary audience was taken to be children and young adults for whom the protagonist served as an example of a hard-working and tenacious hero to be emulated by young Soviets. The target text has been considerably shortened as

  15. Modelling the smart farm

    Full Text Available Smart farming envisages the harnessing of Information and Communication Technologies as an enabler of more efficient, productive, and profitable farming enterprises. Such technologies do not suffice on their own; rather they must be judiciously combined to deliver meaningful information in near real-time. Decision-support tools incorporating models of disparate farming activities, either on their own or in combination with other models, offer one popular approach; exemplars include GPFARM, APSIM, GRAZPLAN amongst many others. Such models tend to be generic in nature and their adoption by individual farmers is minimal. Smart technologies offer an opportunity to remedy this situation; farm-specific models that can reflect near real-time events become tractable using such technologies. Research on the development, and application of farm-specific models is at a very early stage. This paper thus presents an overview of models within the farming enterprise; it then reviews the state-of the art in smart technologies that promise to enable a new generation of enterprise-specific models that will underpin future smart farming enterprises.

    Full Text Available Abstract Background Vitamin A is essential for normal growth, development, reproduction, cell proliferation, cell differentiation, immune function and vision. Hypovitaminosis A can lead to a series of pathological damage in animals. This report describes the case of hypovitaminosis A associated with secondary complications in calves. Case presentation From February to March in 2011, 2-and 3-month old beef calves presented with decreased eyesight, apparent blindness and persistent diarrhea occurred in a cattle farm of Hubei province, China. Based on history inspection and clinical observation, we made a tentative diagnosis of hypovitaminosis A. The disease was confirmed as a congenital vitamin A deficiency by determination of the concentrations of vitamin A in serum and feed samples. Furthermore, pathological and microbiological examination showed that the disease was associated with pathogenic Escherichia coli (E. coli infection and mucosal barriers damage in intestines. The corresponding treatments were taken immediately, and the disease was finally under control for a month. Conclusions To our knowledge, this is the first report of hypovitaminosis A coupled to secondary infection of E. coli in beef cattle, advancing our knowledge of how vitamin A affects infection and immunity in animals. This study could also be contributed to scientific diagnosis and treatments of complex hypovitaminosis A in cattle.

    Full Text Available Season, rainfall, day of rain, temperature, humidity, year and farm are fixed effects, which have been reported to influence milk yield. Those factors are often linked together to contribute to the variation of milk production. This research is addressed to study the fixed effect factors, including lactation curve, which should be considered for genetic evaluation of milk yield based on test day records of dairy cattle. The data were taken from four different farms, which were PT. Taurus Dairy Farm, BPPT Cikole, Bandang Dairy Farm, and BBPTU Baturraden. In total of 16806 test day records were evaluated, consisting of 9,302 at first and 7,504 at second lactation, respectively. The results indicated that fixed effects were very specific and the influences had different patterns for each farm. Consequently, in a genetic evaluation, these factors such as lactation, temperature, year, day of rain, and humidity need to be evaluated first. Ali-Schaeffer curve represented the most appropriate curve to use in the genetic evaluation of dairy cattle in Indonesia.

The spatial analysis suggested significant clustering of positive and negative herds. Presence of streams, wetlands and pastures...... on farms showed a significant association with the presence of infection in cattle herds. Buying animals from positive herds was a risk factor on conventional farms. Additionally, risk of being infected with Fasciola hepatica was higher in non-dairy herds of medium size (>= 30 and ... to dairy and large (>= 100) cattle herds. The observed spatial pattern could be reproduced by predictions of the risk factor model.

    The current review focuses on characterization and conservation efforts vital for the development of breeding programmes for indigenous beef cattle genetic resources in Southern Africa. Indigenous African cattle breeds were identified and characterized using information from refereed journals, conference papers and research reports. Results of this current review reviewed that smallholder beef cattle production in Southern Africa is extensive and dominated by indigenous beef cattle strains adaptable to the local environment. The breeds include Nguni, Mashona, Tuli, Malawi Zebu, Bovino de Tete, Angoni, Landim, Barotse, Twsana and Ankole. These breeds have important functions ranging from provision of food and income to socio-economic, cultural and ecological roles. They also have adaptive traits ranging from drought tolerant, resistance to ticks and tick borne diseases, heat tolerance and resistance to trypanosomosis. Stakeholders in the conservation of beef cattle were also identified and they included farmers, national government, research institutes and universities as well as breeding companies and societies in Southern Africa. Research efforts made to evaluate threats and opportunities of indigenous beef cattle production systems, assess the contribution of indigenous cattle to household food security and income, genetically and phenotypically characterize and conserve indigenous breeds, and develop breeding programs for smallholder beef production are highlighted. Although smallholder beef cattle production in the smallholder farming systems contributes substantially to household food security and income, their productivity is hindered by several constraints that include high prevalence of diseases and parasites, limited feed availability and poor marketing. The majority of the African cattle populations remain largely uncharacterized although most of the indigenous cattle breeds have been identified.

    Full Text Available In this paper, we compare the use and functions of definite and indefinite article-like determiners in Estonian and Finnish. Our main aim is to explore whether the factors that explain the choice of particular determiner forms are similar in Estonian and Finnish. We use a picture-sequence based elicitation experiment to collect spoken narratives from adult native speakers of Estonian and Finnish, and apply non-parametric tree and forest models to analyze the data. Our findings indicate that number of mention and animacy are important predictor variables in both languages, but their exact effect is divergent. We also find that in Finnish, case of the determiner NP proves to be an important factor, while in Estonian, syntactic role of the NP explains some aspects of determiner form choice. Nevertheless, the overall usage frequency of determiners is modest in the Estonian and Finnish data, and the process of grammaticalizing articles is only in initial stages in both languages. *** Artikliga, artiklita?

    The dual-purpose bovine system represents 98.4% of the bovine livestock of Veracruz, the main cattle-producing state of Mexico. This system supplies calves to meat companies, a sector in which Veracruz has been the national leader in the last decade. The objective of the present study was to analyze the effect of the altitudinal zonation of farms on livestock technology and productivity in a microbasin of the Gulf of Mexico where small farms predominate. Structured interviews were applied to producers located in three altitudinal zones (at average altitudes of 50, 140, and 450 m, respectively, for lower, middle, and upper zones). Sample size was 135 farms having similar land surface (within a range of 15-22 ha). The results indicated multiple differences among farms located in the three zones. Farms in the middle and lower zones presented higher productive indicators than those in the upper zone. Differences in herd structure and management resulted in important differences in productivity, income, and profits in milk and calf production. We concluded from this study that altitudinal zonation in Veracruz had a clear effect on the differentiation of small farms, which are representative of dual-purpose cattle. The upper zone performs cattle activity under conditions with greater disadvantages in the analyzed region.

    Schmallenberg virus (SBV) emerged during summer 2011. SBV induced an unspecific syndrome in cattle and congenital signs (abortions, stillbirths and malformations) in domestic ruminants. To study the impact of SBV in Belgium, a phone survey was conducted upon September 2012. Hereto two groups of cattle farmers (A and B) and two groups of sheep farmers (C and D) were randomly selected. Farms from groups A (n = 53) and C (n = 42) received SBV-positive result at RT-PCR in the Belgian National Reference Laboratory (NRL). Farms from groups B (n = 29) and D (n = 44) never sent suspected samples to NRL for SBV analysis but were however presumed seropositive for SBV after the survey. Questionnaires related to reproduction parameters and clinical signs observed in newborn and adult animals were designed and addressed to farmers. As calculated on a basis of farmers' observations, 4% of calves in group A and 0.5% in group B were reported aborted, stillborn or deformed due to SBV in 2011-2012. The impact as observed by sheep farmers was substantially higher with 19% of lambs in group C and 11% in group D that were reported aborted, stillborn or deformed due to SBV in 2011-2012. Interestingly, abortions or stillbirths were not clear consequences of SBV outbreak in cattle farms, and the birth of a deformed animal was an essential condition to suspect SBV presence in cattle and sheep farms. This study contributes to a better knowledge of the impact of the SBV epidemic. The results suggest that SBV impacted Belgian herds mostly by the birth of deformed calves, stillborn lambs and deformed lambs. This work also demonstrates that the birth of a deformed calf or lamb was a trigger for the farmer to suspect the presence of SBV and send samples to NRL for further analyses. © 2015 Blackwell Verlag GmbH.

  10. Risk Factors for Whole Carcass Condemnations in the Swiss Slaughter Cattle Population

    2015-01-01

    We used meat-inspection data collected over a period of three years in Switzerland to evaluate slaughterhouse-level, farm-level and animal-level factors that may be associated with whole carcass condemnation (WCC) in cattle after slaughter. The objective of this study was to identify WCC risk factors so they can be communicated to, and managed by, the slaughter industry and veterinary services. During meat inspection, there were three main important predictors of the risk of WCC; the slaughtered animal's sex, age, and the size of the slaughterhouse it was processed in. WCC for injuries and significant weight loss (visible welfare indicators) were almost exclusive to smaller slaughterhouses. Cattle exhibiting clinical syndromes that were not externally visible (e.g. pneumonia lesions) and that are associated with fattening of cattle, end up in larger slaughterhouses. For this reason, it is important for animal health surveillance to collect data from both types of slaughterhouses. Other important risk factors for WCC were on-farm mortality rate and the number of cattle on the farm of origin. This study highlights the fact that the many risk factors for WCC are as complex as the production system itself, with risk factors interacting with one another in ways which are sometimes difficult to interpret biologically. Risk-based surveillance aimed at farms with reoccurring health problems (e.g. a history of above average condemnation rates) may be more appropriate than the selection, of higher-risk animals arriving at slaughter. In Switzerland, the introduction of a benchmarking system that would provide feedback to the farmer with information on condemnation reasons, and his/her performance compared to the national/regional average could be a first step towards improving herd-management and financial returns for producers.

In Switzerland, the introduction of a benchmarking system that would provide feedback to the farmer with information on condemnation reasons, and his/her performance compared to the national/regional average could be a first step towards improving herd-management and financial returns for producers.

    To evaluate the presence of gastrointestinal parasites on cattle in Indonesia because the prevalence of parasites varies between countries depending on the terrain surrounding livestock farms and investigations in Indonesia have never been performed. Fecal samples from cattle at 35 farms in 7 districts in West Java, Indonesia, has been examined using the floatation or sedimentation methods, and a immunofluorescence assay and experimentally inoculation to mice for Cryptosporidium or Giardia.spp. 153 of 394 examined cattle (38.8%) were infected with gastrointestinal parasites. The prevalence of Eimeria spp., Nematoda spp. (including Oesophagustomum and Bunostomum-like), Fasciola gigantica and Paramphistomum spp. was 22.4%, 11.2%, 12.5% and 3.8%, respectively. Cryptosporidium andersoni (C. andersoni) was also found in two samples. One isolate of this parasite was confirmed to be transmitted to mice, in contrast to the isolates from other countries. although this survey is preliminary, the results shows that the infection of gastrointestinal parasites in Indonesia was not high, but these infected cattle could be as a potential source leading to economic losses in livestock production.

    Full Text Available This study was aimed : (i to know the subsystem implementation and agribusiness planning inbeef cattle fattening; (ii to count the profit of beef cattle farming; (iii to analyze the effect ofagribusiness subsystem implementation and agribusiness planning to beef cattle fattening profit. Thisstudy was carried out using survey method and the elementary units were feedlot farmers. The samplewas determined by Purposive Quota Sampling Method on 112 respondents spread across five regencies,namely Blora, Rembang, Grobogan, Wonogiri, and Boyolali. Data were collected from primary andsecondary sources. The data analysis used quantitative descriptive and inferential statistics method,which include scoring, financial, and multiple linear regression analysis. The results showed that : (i theimplementation of agribusiness subsystem (including preproduction subsystem, marketing, andagribusiness support services and agribusiness planning were not so good category, while the cattlefarming subsystem was moderate category; (ii the average of farming scale in each feedlot farmer was2.95 head of cattle with the profit rate was IDR 1,044,719 per fattening period during 6.68 months(equivalent to IDR 156,395 per month; (iii agribusiness subsystem and agribusiness planning hadsignificant impact on feedlot farmer profit simultaneously, but preproduction subsystem and theagribusiness support services subsystem partially had a significant impact on feedlot farmer profit.

    Mycobacterium tuberculosis is the main causative agent of tuberculosis (TB) in human and Mycobacterium bovis commonly causes tuberculosis in animals. Transmission of tuberculosis caused by both pathogens can occur from human to animals and vice versa. In the current study, M. tuberculosis, as confirmed by polymerase chain reaction (PCR) using primers targeting 3 regions of difference (RD4, RD9 and RD12) on the genomes, was isolated from cattle originating from two epidemiologically unrelated farms in the Eastern Cape (E.C) Province of South Africa. Although the isolates were genotyped with variable number of tandem repeat (VNTR) typing, no detailed epidemiological investigation was carried out on the respective farms to unequivocally confirm or link humans as sources of TB transmission to cattle, a move that would have embraced the 'One Health' concept. In addition, strain comparison with human M. tuberculosis in the database from the E.C Province and other provinces in the country did not reveal any match. This is the first report of cases of M. tuberculosis infection in cattle in South Africa. The VNTR profiles of the M. tuberculosis strains identified in the current study will form the basis for creating M. tuberculosis VNTR database for animals including cattle for future epidemiological studies. Our findings however, call for urgent reinforcement of collaborative efforts between the veterinary and the public health services of the country.

    Full Text Available Cattle breeding is a very important part of agricultural production in Bosnia and Herzegovina (B&H, and milk production has a vital place in cattle breeding production. From an economic point of view, milk production is interesting as it is a daily production which presupposes faster marketing, which accelerates capital movement in agriculture, which in turn enhances liquidity. This research uses analyses of the existing state in milk production. The collected data are processed and cost calculation has been designed which enables the analysis of economic indicators of 4 dairy farm production models in B&H. Based on the collected data on features and values of dairy farm production models in B&H an analysis of expert evaluation was conducted as input data for DEXi method. The aim of this paper is to ascertain the basic indicators of business success of 4 dairy farm production models in B&H. Production-ecological, economic and socio-political features of the mentioned dairy farm models were analyzed. Based on the used criteria a rate of dairy farm production models using DEXi method was conducted. The results of the research in this paper using DEXi method show that the best model for dairy farm is model number four, which includes 45 milk cows.
