Sixty-one Mycobacterium avium subsp. paratuberculosis isolates from cattle and deer from the Buenos Aires province, an important livestock region in Argentina, were typed by restriction fragment length polymorphisms (RFLP) analysis based on IS900. Four different RFLP patterns (designated ‘A’, ‘B’, ‘C’ and ‘E’) were identified in BstEII digests of genomic DNA. The most frequently observed type, pattern ‘A’, was found in 46 isolates (75%). The second, pattern ‘E’, included 8 isolates (13%), while the third, pattern ‘B’, included 6 isolates (10%). Pattern ‘C’ was found for only one isolate. All of the deer isolates were classified as pattern ‘A’, while cattle isolates represented all four RFLP patterns. Twenty-one isolates representing the four different BstEII-RFLP patterns were digested with PstI. Twenty isolates showed identical PstI-RFLP pattern. BstEII-RFLP patterns from Argentine cattle and deer were compared with patterns found in cattle, goat, deer, rabbit, and human isolates from Europe. The most common pattern in Argentina, pattern ‘A’, was identical to a less frequently occurring pattern R9 (C17) from Europe. The other Argentine patterns ‘B’, ‘C’ and ‘E’, were not found in the Europe. These results indicate that the distribution of M. avium subsp. paratuberculosis genotypes in the Buenos Aires province of Argentina is different from that found in Europe. 相似文献

OBJECTIVE: To determine sheep farmers' attitudes to and beliefs about ovine footrot, and to improve their knowledge about the diagnosis, control and eradication of this disease. METHOD: Eighteen workshops, involving 291 farmers, were conducted across Victoria in the spring of 1996. The workshops were designed as small-group discussions with a maximum attendance of 20 farmers to encourage active participation. All participants completed questionnaires before each workshop and 12 to 40 weeks after the last workshop. RESULTS: Before the workshops the farmers had a poor understanding of the principles of diagnosis, control and eradication of footrot. For example, only 50% knew the footrot organism survived in soil for less than 7 days, over two-thirds did not know the reason for paring sheep's feet during an eradication program, and only 31% realised cattle were a potential source of footrot infection for sheep. After the workshops, understanding about footrot was significantly improved; 87% said Dichelobacter nodosus survived in soil less than 7 days, 71% knew the reason for paring sheep's feet and 64% realised that cattle were a potential source of footrot infection. As well as improved knowledge, change of attitude among farmers is fundamentally important if virulent footrot is to be successfully controlled and eradicated. The workshops successfully initiated this process; 40% of farmers thought the workshops changed their attitudes to footrot, while 37% said they gained an increased understanding of other people's opinions about the disease. CONCLUSION: Farmers' poor understanding of ovine footrot is a constraint to the programs aimed at controlling this disease. Small group workshops may be an effective way to influence farmers' attitudes and beliefs, and could facilitate the effectiveness of regulatory disease control programs. 相似文献

This review summarises current control measures for clinical paratuberculosis (Johne’s disease; JD) in New Zealand pastoral livestock. Most New Zealand sheep, deer, beef and dairy cattle herds and flocks are infected by Mycobacterium avium ssp. paratuberculosis (Map). Dairy cattle and deer are mostly infected with bovine (Type II), and sheep and beef cattle with ovine (Type I) strains. Control in all industries is voluntary. While control in sheep and beef cattle is ad hoc, the dairy and deer industries have developed resources to assist development of farm-specific programmes.
The primary target for all livestock is reduction of the incidence rate of clinical disease rather than bacterial eradication per se. For dairy farms, a nationally instituted JD-specific programme provides guidelines for risk management, monitoring and testing clinically suspect animals. While there is no formal programme for sheep farms, for those with annual prevalences of clinical disease >2%, especially fine wool breeds, vaccination may be a cost effective control option. The deer industry proactively monitors infection by a national abattoir surveillance programme and farmers with an apparent high disease incidence are encouraged to engage with a national network of trained consultants for management and control advice. Evaluation of the biological and economic effectiveness of control in all industries remains to be undertaken. Nevertheless, opportunities exist for farmers, who perceive significant JD problems in their herds/flocks, to participate in systematic best-practice activities that are likely to reduce the number of clinical infections with Map on their farms, and therefore the overall prevalence of JD in New Zealand’s farming industries. 相似文献

Infections with gastrointestinal roundworms are an important cause of production losses in sheep and cattle. Worm control is a vital part of health and production management in sheep flocks and cattle herds in the UK, and good control is highly dependent on effective anthelmintics. Unfortunately, a direct and unavoidable consequence of using anthelmintics to control worm populations is selection for individuals that are resistant to the chemicals used. If left unchecked, anthelmintic resistance (AR) could prove to be one of the biggest challenges to sheep and cattle production and animal welfare within the UK. As a consequence of increasing reports of AR in sheep, a working group, "SCOPS" (sustainable control of parasites in sheep) was formed in 2003 with representatives from the UK sheep industry to promote practical guidelines for sheep farmers and their advisors. This led to the production of guidelines for 'sustainable worm control strategies for sheep' intended for veterinarians and sheep advisors, plus ongoing promotional literature aimed at farmers. Whilst there is some evidence of emerging resistance in roundworms of cattle, it appears to still be at a very low level in the UK. However the potential presence of such AR in cattle worms has been seen as a timely warning, which if ignored, could lead to a not dissimilar AR situation to that seen in sheep, and in other cattle areas around the world. Reports of AR in UK cattle nematodes have generally been limited to a small number of anecdotal reports of treatment failure with some macrocyclic lactone (ML) products, especially those formulated as pour-on preparations, and invariably involving the dose-limiting species, Cooperia oncophora. As a consequence of these observations, guidelines have been produced similar to those for sheep, for sustainable worm control strategies for cattle "COWS" (control of worms sustainably), and were launched in May 2010. Uptake and effectiveness of SCOPS recommendations are currently being monitored in collaboration with the UK animal health industry, and similar proposals are being considered for uptake of COWS guidelines following the launch this year. 相似文献

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

Zoonotic diseases such as bovine tuberculosis (TB) that infect wildlife and livestock are particularly difficult to eradicate where wild animals make extensive use of agricultural landscapes. Transmission of TB between cattle (Bos taurus) and wild elk (Cervus elaphus) in southwestern Manitoba, Canada remains poorly understood but there is a risk when comingling occurs on summer pasture. Elk use of cattle summer pastures was assessed using ecological data (187 VHF and 25 GPS collared elk monitored over four years representing 8% of the elk population). Local knowledge was documented by conducting interviews and participatory mapping exercises with 86 cattle producers (98% of those within the study area). Of the 294 cattle pastures mapped by farmers, 13% were used by radio-collared elk, 38% were reported by farmers as being used by elk, and 42% were identified as used by elk when both when all datasets were combined. Cattle pastures that had been used by elk and those that had no elk were compared using binary logistic regression based on each of the three datasets (i.e. farmer observations, radio-collared elk on pasture, and combined dataset). For all three datasets, distance to protected area and proportion of forest cover on the cattle pasture were identified as the most and second most important predictor variables, respectively. There was strong agreement among the relative probabilities of elk occurrence on each pasture derived from the resource selection function (RSF) models developed using farmer interviews and elk collaring data. The farmer interview and collar datasets were then combined to generate a final integrated RSF map summarizing the probability of elk–cattle comingling and were contrasted over each of four cattle grazing seasons (spring, early summer, late summer, and autumn). These predictive maps indicate that use of cattle pastures by elk is extensive, particularly in spring and early summer. Farmer observations indicate that elk and cattle share water sources and livestock mineral supplements on pasture. Local knowledge and conventional ecological data complement and validate one another and help us better understand the temporospatial aspects of shared space use among wildlife and livestock and more generally the risks of disease transmission in agricultural landscapes. 相似文献

To characterise the urban livestock keeping practices and constraints in Kisumu municipality, Kenya, a questionnaire survey was carried out. Thirty-four contact farmers were interviewed on general farm characteristics and production constraints. The farming activities were categorised as either livestock only (41%), or mixed crops and livestock (59%). The surveyed farmers kept mainly cattle (100%), chickens (82%) and goats (74%). Most (94%) of the farmers had kept livestock for prolonged periods mainly for income generation (97%) and domestic consumption (59%). These data show that livestock keeping was popular and could be harnessed to increase food security, although the farmers kept mainly low-producing indigenous cattle (98%) which were grazed on unutilised land. The main production constraints mentioned by farmers included diseases (100%), poor fertility (68%) and lack of feed (56%). The diseases varied with species of ruminants and included lumpy skin disease (71%), diarrhoea (65%) and helminthosis (62%). The source of advice on management and treatment of the livestock was almost equally from private and government veterinary personnel. To improve livestock productivity, it is recommended that key stakeholders address the constraints mentioned in this study and in particular that the occurrence of diseases should be investigated with a view to developing sustainable control strategies. 相似文献

In India, insurance market especially in agricultural sector is usually underdeveloped. The idea of livestock insurance emerged in India before three decades, yet, it has not operated in a significant way till date. It is well noted that livestock insurance scheme is the relevant strategy in managing different risks related to livestock farming but very little attention has been paid to address the livestock insurance needs of the dairy farmers. This study, therefore, addresses the basic question that how many people and to what extent they are willing to pay for livestock insurance and determine the main factors which influence insurance participation of dairy farmers. The data was collected from Gorakhpur district of Uttar Pradesh in India with a sample survey of 120 cattle and buffalo farmers. For eliciting willingness to pay, a contingent valuation scenario was presented to dairy animal owners in the group of five to six. A logit discrete binary regression model was used to know the factors influencing adoption of livestock insurance. The results suggest that most of the farmers were willing to participate in cattle and buffalo insurance. The amount of premium varies across different breeds of dairy animals. The low level of education of many dairy farmers have negatively influenced the decision to purchase livestock insurance. Farmers having more experience in rearing dairy animals are more likely to be willing to pay for cattle and buffalo insurance. 相似文献

Meat inspection records in an abattoir located in Shiraz, a city in southwest Iran and the capital of Fars province, during a 5-year period from 20 March 1999 to 19 March 2004 were used to determine the prevalence of hydatidosis in sheep, cattle, and goats in the region. A total of 844,039 animals (cattle 131,716; sheep 577,090; goats 135,233) slaughtered in the 5-year period and overall 34,856 (4.1%) livers and 123,402 (14.62%) lungs were condemned. Hydatidosis was responsible for 28.7 and 15.4% of total livers and lungs condemnations, respectively. The overall trend for all livestock and in both organs was a significant downward one. The annual prevalence of liver condemnations due to hydatidosis was decreased from 2.1, 1.8, and 1.0% in 1999-2000 to 0.62, 0.33, and 0.20% in 2003-2004 for cattle, sheep, and goats, respectively. The corresponding features for lung condemnation due to hydatidosis were relatively higher than liver, declining from 3.0, 4.6, and 4.4% in 1999-2000 to 1.3, 1.5, and 0.56% in 2003-2004, for cattle, sheep, and goats, respectively. Greater awareness among farmers, destruction of organs containing hydatid cysts, prevention of access of dogs to raw offals and implementation of national rabies control program could be responsible factors. Data showed significant seasonal pattern for hydatidosis in all species. Liver condemnations due to hydatidosis were higher in the spring and summer for sheep, whereas lung condemnations were higher in summer for both sheep and goats. Liver and lung condemnations in cattle were higher in winter. This could be attributed to various factors such as sources of slaughtered animals, changes in management practice and ecological factors. The overall trend was relatively the same when annual condemnations were adjusted for the effect of seasonal variation. The present survey provides baseline data for the future monitoring of this potentially important parasitic disease in the region. 相似文献

Trypanosomosis is an important disease affecting humans as well as animals. It remains a big constraint to livestock productions in tropical areas. The objective of this study was to assess the importance of trypanosomosis among cattle diseases in Burkina Faso, mainly in tsetse-challenged areas, and to capture information on how farmers apply available methods for controlling the disease. A survey has been carried out in 29 villages of Burkina Faso in three regions (north, southwest, and west regions). One hundred and thirty-four cattle breeders were interviewed individually with a questionnaire. The results indicate that among the 16 diseases mentioned by cattle breeders, trypanosomosis is the most important one in tsetse-challenged areas. Overall, 76.12 % of the breeders mentioned it as the most important disease, while 54.55 % of the farmers in the southwest region and 70.91 % of the farmers in the west region ranked it as a priority disease. Chemoprophylaxis/chemotherapy is widely used as a control method. Isometamidium chloride and diminazene aceturate were used by 53.49 and 46.52 % of the responders, respectively. Among farmers, 85.55 % ranked diminazene aceturate as the less efficient while 14.45 % ranked isometamidium chloride as the most efficient trypanocid. Trypanocidal drug quality and drug resistance were raised as a major concern by 30.77 and 50 % of the respondents, respectively. According to them, zebu cattle are more susceptible to trypanosomosis than taurine Baoule cattle and their crosses with zebu, emphasizing that crossing susceptible breeds with trypanotolerant ones, could be used as part of an integrated control strategy. 相似文献

Leptospirosis is an endemic disease in Latin America, caused by pathogenic bacteria of the genus Leptospira. It is considered one of the main causes responsible for the negative economic impact on global livestock by causing reproductive problems. The research aimed to determine the prevalence of leptospirosis in cattle, sheep, and goats at consorted rearing in the micro-region of Teresina, Piauí state, northeastern Brazil, as well as to identify prevalent serovars and risk factors associated with seroprevalence. Serum samples were analyzed in 336 sheep, 292 goats, and 253 cattle using microscopic agglutination test (MAT). Overall, 378 samples were positive to MAT, with seroprevalence of 42.9%. The prevalences in cattle, sheep, and goats were 50.5, 40.5, and 34.6%, respectively. All herds presented at least one seropositive animal; the Hardjo/Wolffi serovar association was the most common in cattle and Icterohaemorrhagiae in goats and sheep. Beef production (OR?=?4.9), cattle herd over 35 animals (OR?=?4.0), feeding on pasture (OR?=?6.4), weir and/or stream as water source (OR?=?2.1), and no veterinary services (OR?=?2.9) were risk factors for cattle infection. For sheep, intensive management system (OR?=?5.3), suspended slatted facilities (OR?=?2.2), more than 20 sheep in reproductive age (OR?=?1.9), and absence of deworming (OR?=?3.5) were the risk factors, while for goats, the identified risk factors were sheep herd over 52 animals (OR?=?1.9) and no veterinary services (OR?=?1.8). We conclude that the infection was spreading in consorted herds in this region. Thus, it would be interesting and important to conduct educative activities to farmers on the economic impacts of this disease and the need of preventive and control strategies mainly focused on sanitary measures and animal handling. 相似文献
