猪乙型脑炎又称为日本乙型脑炎。流行性乙型脑炎是由日本乙型脑炎病毒感染引起的一种人畜共患病,蚊虫是该种疾病的中间传播媒介。猪乙型脑炎是国家二类动物疫病,世界卫生组织规定必须报告的动物疫病。猪场中暴发猪乙型脑炎后,不但会对猪养殖产业造成严重危害,还会严重损害人类健康。笔者主要结合实际情况就一起猪乙型脑炎的诊断和综合防治进行分析.  相似文献

The purpose of this paper is to explain what the ‘Selectadog’ programme is, to emphasize some things it is not, to show what it is for and who benefits, to detail the forms that it is in, to give some indication as to how it works and to relate some of the experiences of using ‘Selectadog’ in the United Kingdom and elsewhere since 1975. ‘Selectadog’ is a programme designed to match up the characteristics of the more popular breeds of dog to the circumstances of potential owners, as identified by means of a questionnaire. Its purpose is to give guidance to people thinking about getting a dog and above all to make them think through the points they should be considering about fitting a new dog into their lives. At best and it is quite a good best, it can give the prospective owner a number of leads and a positive starting point. It also provides a good deal of free advice and information to allow the new owner to begin a prolonged period of responsible pet animal ownership, without putting them off unnecessarily.  相似文献

Incisional abdominal hernias in three horses were repaired, using synthetic mesh with a fascial flap overlay. The repair of large ventral abdominal hernias of horses can be accomplished by using synthetic mesh that is sutured across the defect. This material can be placed subperitoneally, retroperitoneal but subfascial, retrofascial and subfascial, or retroperitoneal but subfascial with a fascial overlay. Advantages of using this material are that it can be used for repair of large hernias, it is easy to apply, it is strong and flexible, and it is less likely to be rejected, when compared with other synthetic materials.  相似文献

基于BP神经网络的饲料产品品质预测方法   总被引:1,自引:0,他引:1  
饲料加工生产过程是一个非常复杂的系统,其产品品质受原料特性和加工参数的影响,且各加工参数之间相互关联,很难用精确的数学模型来反映原料特性和加工参数与产品品质的关系。利用BP神经网络能自身从样本数据中提取相关的信息,并依据数据建立模型,可以有效准确地预测产品品质。试验结果表明,产品淀粉糊化度预测结果与真值的相关系数R在0.99以上,产品水分含量预测结果与真值的相关系数R在0.97以上,预测效果理想。因此,BP神经网络预测模型用于饲料产品加工品质预测是可行的。  相似文献

American veterinary medical education stands at a crucial point. To maintain the status quo and to meet ever-increasing societal needs within the United States and globally, it is essential that the veterinary medical profession expand its horizons and capabilities. If it does not, it will lose its current status. The profession faces a crucial shortage in the workforce it needs both to continue to perform its current functions and, more importantly, to meet its growing responsibilities. This is not a new situation, and the profession can learn from its past successes and failures. Action is necessary. The profession has the capability and expertise to meet these challenges, but it must activate these skills in order to succeed.  相似文献

Extract

It is significant that only 13 of nearly 400 delegates Who attended World Conference III on Breeding Endangered Species in Captivity listed themselves as having veterinary qualifications. For many people, a representation of just over 3 percent would seem to be par for the course when it comes to veterinary involvement with wildlife, for it is well-known that the majority of the profession have been trained to tend domestic animals and, whilst expressing a concern for wildlife, freely admit their incompetence to deal with it. Yet it is interesting to find that many of the world's leading zoo directors and curators have a veterinary background, and have been accepted by their zoologist counterparts as being at least their equals, if not their betters. Consequently, whilst veterinarians represent only a small proportion of the work force in zoos and wildlife parks, their influence is considerable.  相似文献

儒学是中国传统社会最重要的文化思想学说,它兼容并包、与时俱进,最全面地体现了中国传统文化。儒学为中国文化提供了一个巨大的载体,各式各样的思想都可以在其中找到自己的位置,它们在儒学的外衣包裹下,表达的却是自己独特的思想内核。正是凭借载体性,儒学作为“显学”,在中国思想史上占有极重要的位置。  相似文献

Although this article is not a comprehensive review of ocular biology and disease across the millions of invertebrate species, it is hoped that it highlights the surprising gene homologies that influence ocular development despite the dramatic differences in resulting ocular development and final morphology. In the same way that ocular anatomy and physiology is undergirded by similarities in the genetic foundation of the eye, it is to be expected that eye disease in invertebrates, as it is studied in more depth, will show substantial homologies with the eye disease of the vertebrates that veterinary ophthalmologists are more used to treating.  相似文献

In the preceding pages, the various components of an examination have been described. Each clinician will formulate his own method of utilizing these components. The following are suggested steps in a practical approach to the diagnosis of lameness. Evaluate the conditions under which restraint of the animal is possible (corral, free stall, stanchion barn). Assess the temperament, physical strength, and general amenability of the animal to be examined. If the animal is at liberty, its movements can be studied. If it is standing quietly observe it. If the animal is tied up and it seems feasible to examine the animal while it is walking, observe the animal and take its history while it is still tied up. Aggressive and wild animals should be observed, but little beneficial information will be gained from a regional approach to evaluating movement at this stage. Even if the seat of lameness seems to be in the proximal limb, it is mandatory in every case to examine the hooves and interdigital space at some stage during the evaluation. However, if the probability of proximal lameness is high, the clinician may proceed to make a complete evaluation, which would include studying the quality of movement before checking that the distal extremity is normal in every way. If the clinician decides to proceed with an examination of the digital region and is unable to locate a causative lesion in the extremity, he would then evaluate movement and manipulate and palpate the proximal limb. If no cause of the lameness becomes apparent, the nerve supply to the extremity would then be blocked.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献
