奶牛乳房炎是奶牛常见的三大疾病之一，其制约着奶牛养殖业发展，并且常年造成巨大的经济损失。直接在奶牛上进行实验研究的成本较高、操作不便及无法进行标准化管理，这在一定程度上影响了对奶牛乳房炎的研究及防治。近年来，国内外学者开始选用小鼠建立乳腺炎疾病模型，该模型具有费用低、耗时少、效率高及性价比高等优点，解决了使用奶牛成本高及无法进行标准化管理等问题。本文对小鼠乳腺炎模型的构建、中草药对小鼠乳腺炎的作用机制及防治等进行综述，为开发中草药防治奶牛乳腺炎的研究提供一定的理论基础。 相似文献

我国应用中草药防治牛病的历史悠久,积累了很多宝贵经验,其中古代有著名的<神农本草经>、<牛经大全>、<牛经备要医方>等兽医古籍,医牛方共205个,据张克家主编<中兽医方剂大全>(1994)记载的医牛方就有684个.从奶牛常见病来看,主要是乳腺疾病、产科疾病、肢蹄病三大病;还有消化系统疾病和营养代谢病.而中草药对这些疾病的预防和治疗有明显的作用;且易投药、成本低、无抗药性及残留,是奶牛保健和无公害牛奶生产的必备良药.通过奶牛疾病防治中兽药系列化产品的开发研制,在大理、昆明地区奶牛饲养户中进行试验,反复组方筛选,形成具有云南民族中医药特色的"土兽药".现将有关研制验方加以整理总结,供广大奶牛养殖户参考使用. 相似文献

热应激对奶牛的危害不仅仅是产奶性能的降低,更严重危害着奶牛的生殖与繁殖机能。在热应激作用下,奶牛发情不明显、受胎率下降、产科疾病发病率升高。据笔者近3年对山东济南周边各中小型奶牛场和散养户在7~9月份奶牛发病情况调查发现,产科疾病发病率占暑期奶牛疾病的40％左右。可以说,热应激已经成为高热季节奶牛繁殖的拦路虎,如何做好热应激期间奶牛产科疾病的预防对于发展奶牛生产具有重要意义。针对热应激对奶牛繁殖性能的严重危害,我们总结了生产中一些改善和提高奶牛繁殖性能、防治产科疾病的具体措施,以便与广大奶牛养殖者共同交流： 相似文献

Survey responses from 75 randomly selected dairy producers on Prince Edward Island were summarized to obtain a demographic picture of the dairy industry in this province and to determine information management practices and demands for the future. The results indicate a preparedness for dairy production in the future. 相似文献

OBJECTIVE: To give an account of the views held by Australian veterinarians who work with horses on the future of their professional field. METHOD: Questionnaires were mailed to 866 veterinarians who had been identified as working with horses, and 87% were completed and returned. Data were entered onto an Excel spreadsheet, and analysed using the SAS System for Windows. RESULTS: Their future prospects were believed to be very good or excellent by >60% of equine veterinarians but by only 30% of mixed practitioners seeing < 10% horses. The main factors believed likely to affect these prospects were the strength of the equine industries and the economic climate affecting horse owners, followed by the encroachment of cities into areas used for horses, competition from other veterinarians including specialist centres and from non-veterinary operators, and their ability to recruit and retain veterinarians with interest, experience and skill with horses. Urban encroachment, competition and recruitment were especially important for those seeing few horses. Concerns were also expressed about the competence and ethical behaviour of other veterinarians, the physical demands and dangers of horse work, the costs of providing equine veterinary services and of being paid for them, the regulatory restrictions imposed by governments and statutory bodies, the potential effects of litigation, and insurance issues. For many veterinarians in mixed practice these factors have reduced and are likely to reduce further the number of horses seen, to the extent that they have scant optimism about the future of horse work in their practices. CONCLUSION: Economic and local factors will result in an increasing proportion of equine veterinary work being done in specialised equine centres, and the future of horse work in many mixed practices is, at best, precarious. A key factor influencing future prospects will be the availability of competent veterinarians committed to working with horses. 相似文献

A retrospective cohort study of Irish cattle herds investigated whether the severity of a herd’s bovine tuberculosis (BTB) breakdown was a predictor of the hazard of a future BTB breakdown in that herd. Data on 10,926 herds not having had BTB in 1995 (the “non-exposed” group) were obtained using a 10% random sample from all herds without BTB in 1995. Data on 6757 herds that had a new BTB breakdown in 1995 (the “exposed” group) were obtained and categorized into five increasing exposure-severity classes based on the total number of standard reactors (to the single intra-dermal comparative cervical tuberculin test) detected during the breakdown. Exposed herds were deemed to be free of BTB after they passed a 6-month check test; non-exposed herds were deemed free as of the date of the first negative herd-test in 1995.
In the 5 years after 1995, 18% of the non-exposed herds had a BTB breakdown, whereas 31% of the exposed herds had a subsequent breakdown. Relative to the hazard for non-exposed herds, the hazard for the first future singleton standard reactor breakdown, was 1.6-times higher for exposed herds with only 1 standard reactor in 1995, and 1.8-times higher for those exposed herds with 4–8 standard reactors during the 1995 episode. When the outcome for future breakdowns was 2 or more standard reactors, the hazard ratios ranged from 1.6 for exposed herds with only 1 standard reactor in 1995 up to 2.9 in exposed herds with 8 or more standard reactors during the 1995 episode. The latter hazard ratio varied over time, decreasing to 1.7 after 3 years of risk. The hazard of a future BTB breakdown increased directly with number of cattle in the herd, a positive history of previous BTB in the herd, and the local herd prevalence of BTB. The presence of confirmed BTB lesions in reactor cattle was not predictive of the future breakdown hazard when the effects of other factors were controlled. 相似文献

Extract Following the completion of the first phase of the Brucellosis Eradication Scheme in August 1977. when all eligible cattle were finally brought under test, a major review of the scheme and projections for future progress were published in the Veterinary Journal. At that time Dr Adlam wrote of the likelihood of changes as the scheme moved from the initial phase towards final eradication. A further five years have now passed and although the scheme has been constantly adapted to changing circumstances it is again timely to review progress. consider future trends and reassess current strategies. 相似文献
