Seventy-two dairy practitioners in the state of Wisconsin participated in a telephone survey to determine the prevalence of a seasonal vesicular skin disease of dairy cows. Results of the survey indicated that there was widespread recognition of a skin disease that appears clinically similar to bovine herpes mammillitis but with the following differences: sporadic occurrence, non-infectious pattern of occurrence, almost exclusive predilection for first-calfheifers with severe udder edema, and dry gangrene and sloughing of teats.
威斯康辛州72名奶牛场从业人员参加了一项电话调查,以确定奶牛季节性水疱性皮肤病的患病率。调查结果表明,人们普遍认识到一种皮肤疾病,其临床表现与牛疱疹性乳炎相似,但有以下区别:散发发生,非传染性发生,几乎只发生于有严重乳房水肿的初产母牛,以及干性坏疽和乳头脱落。

This review summarizes research indicating that adverse metabolic conditions, particularly marked periparturient loss of body condition body condition exert acute and latent effects on fertility by negatively influencing follicle development and subsequent luteal function. It is concluded that nutritional management directed to minimizing loss of body condition will result in improved fertility.
本文综述了研究表明,不良代谢状况,特别是围产期明显的身体状况丧失,通过对卵泡发育和随后的黄体功能产生负面影响,对生育能力产生急性和潜在的影响。因此,以尽量减少身体状况损失为目标的营养管理可以提高生育能力。

Megatrends Affecting the U.S. Dairy Industry 影响美国乳制品行业的大趋势
Pub Date : 2019-08-08 DOI: 10.21423/bovine-vol1993no27p111-119
A. Novakovic
In the last few years the dairy industry, including farmers and processors, has been buffeted by volatile prices that have resulted in large part because of declining milk price supports. While this has been a very important issue of immediate concern, numerous nonprice factors have played and continue to play an equally important role in shaping the future of the American dairy industry. In this paper, I will discuss what might be called mega trends shaping milk production and consumption in the U.S.
在过去几年里,乳品行业,包括奶农和加工商,一直受到价格波动的冲击,这在很大程度上是因为牛奶价格支持的下降。虽然这是一个非常重要的直接问题,但许多非价格因素在塑造美国乳制品行业的未来方面已经并将继续发挥同样重要的作用。在本文中,我将讨论什么可能被称为大趋势塑造牛奶生产和消费在美国

Herd Health Monitoring and Records Analysis 畜群健康监测与记录分析
Pub Date : 2019-08-08 DOI: 10.21423/bovine-vol1993no27p88-101

Food animal veterinarians who wish to do more than just react to their clients' problems need to become involved in the management of the farm. To do so, they must become information managers. They must be able to extract information from farm record systems. They must also become computer literate and be comfortable with data and numbers. While there will always be a need to look at the individual animal, more and more herd problems will be investigated by examining record systems, not just animals. To do so efficiently, veterinarians must be adept at data management. In addition to information about the specific farm, veterinarians must also understand the general conditions facing agricultural industries in the area.
希望做的不仅仅是对客户的问题做出反应的食用动物兽医需要参与农场的管理。要做到这一点,他们必须成为信息管理者。他们必须能够从农场记录系统中提取信息。他们还必须精通计算机,熟悉数据和数字。虽然总是需要观察单个动物,但越来越多的群体问题将通过检查记录系统来调查,而不仅仅是动物。为了有效地做到这一点,兽医必须善于数据管理。除了有关特定农场的信息外,兽医还必须了解该地区农业产业面临的一般情况。

Blood samples were taken just before slaughter and urine urine samples were taken after slaughter from 67 healthy Italian Friesian cows aged 4-7 years. None of the cows had any clinical or haematological signs of kidney damage, but 46 had macroscopic or histological signs of kidney damage. The remaining 21 were used to calculate serum and urine reference values for urea, creatinine, proteins, N-acetyl-glucosaminidase, gamma-glutamyl transferase, lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase and alkaline phosphatase.

Ethical Marketing of Veterinary Pharmaceuticals 兽药伦理营销
Pub Date : 2019-08-08 DOI: 10.21423/bovine-vol1993no27p132-134
G. L. Upham
Marketing is the total activities by which the transfer of goods from seller to buyer is affected. Veterinarians have a wide range of feeling about marketing of veterinary pharmaceuticals as it relates to food animal practice. Some veterinarians embrace pharmaceutical sales as part of their practice and routinely dispense both legend and over-the-counter (OTC) products to their clients. Others attempt to distance themselves from any phase of the marketing process, but if a veterinarian is involved in food animal practice and authorizes the use of legend drugs, they are involved and assume the liability associated with their use. The Federal Food, Drug, and Cosmetic Act mandates this involvement by requiring legend veterinary drugs be dispensed only by or on the order of a licensed veterinarian in the course of their professional practice.
市场营销是影响商品从卖方向买方转移的全部活动。兽医对兽药的营销有广泛的感觉,因为它涉及到食用动物实践。一些兽医将药品销售作为他们工作的一部分,并经常给他们的客户分发传说和非处方(OTC)产品。其他人则试图与营销过程的任何阶段保持距离,但如果兽医参与食用动物实践并授权使用传奇药物,他们就参与其中并承担与使用相关的责任。《联邦食品、药品和化妆品法》规定,传奇兽药只能由有执照的兽医在其专业实践过程中配药或在其命令下配药。
