奶牛隐性乳房炎与胎次、年龄关系的探讨

奶牛隐性乳房炎是一种复杂的导致奶牛业经济损失最严重的疾病,是奶牛养殖过程中的常见病之一,其发病率高。为了摸清南通红梅乳业牧场隐性乳房炎的发病情况,笔者用北京亚临床乳房炎快速诊断液做试验,从胎次、年龄等两个方面分别调查了隐性乳房炎的头阳性率、乳区阳性率,并进行卡方分析,得出奶牛隐性乳房炎的发病率同胎次、年龄等因素之间存在着密切的关系,随着胎次和年龄的增加隐性乳房炎的发病率呈上升趋势。     

Examination of the bovine nervous system

Neurologic evaluation of cattle requires a complete history, a basic physical examination, and knowledge of the more common diseases affecting the nervous system of dairy and beef cattle. It is not time-consuming to perform a complete neurologic examination. With interest on the part of the practitioner and reasonable and careful observation, the experience can be rewarding and challenging, leading to accurate diagnoses, prognoses, and good patient care and herd health management.

Special observations related to a common paramphistome induced hepatic biliary infestation in cattle, a serious malignant head catarrh outbreak in which possible cattle to cow aerosol transmission occurred. Trismus observed in some cattle with malignant head catarrh was associated with arteriolitis and ganglioneuritis of the V cranial nerve. Parasitic, bacterial, viral toxic and neoplastic diseases are recorded in the various species. The occurrence of fatal chronic fluorosis in laboratory guinea pigs and cerebral nematodiasis in a Thoroughbred racehorse are documented.

     

Teat laceration repair in cattle.

Teat injuries are common in dairy cattle, and, compared with other frequently occurring diseases, these injuries often result in premature culling of affected cows. Teat injuries can be divided into two categories (external or internal injuries). All the different types of injuries/diseases, diagnostic approaches, and therapies have been described in a previous chapter. This chapter focuses only on teat lacerations (external injury).     

Surgery of the bovine large intestine

Cecal dilatation and volvulus are common entities in dairy cattle, whereas cecal torsion is not often encountered. These diseases have been related to excessive volatile fatty acid production. Obstruction of the remainder of the large colon may be simple or strangulating in nature. These obstructions are relatively rare. Clinical signs, surgical management, and surgical complications of diseases of the cecum and large intestine are discussed.     

Livestock farmers' perception and epidemiology of bovine trypanosomosis in Kwale District, Kenya

We did cross-sectional surveys in Kwale District, Kenya to determine the epidemiology of bovine trypanosomosis and livestock owners' perceptions of the disease. The surveys involved relative importance of trypanosomosis, examination of the current disease constraints, current control practices and drug-use patterns. Informal meetings were held with farmers and cattle census undertaken. Tsetse-fly densities and trypanosomosis prevalences in cattle were determined. A total of 132 farmers were interviewed. Trypanosomosis, anaplasmosis, East Coast fever, foot-and-mouth diseases were reported to be the major constraints to livestock production. Trypanosomosis was the most important compared to other diseases. Chemotherapy was the most widely used method of controlling the disease. Farmer-based tsetse-control technologies were poorly adopted. Respondents were quite knowledgeable on the symptoms, causes and treatment of trypanosomosis. Glossina austeni, G. brevipalpis and G. pallidipes were found in the area; the latter was the most common (0.2-738 flies/trap). Trypanosoma congolense and T. vivax were found in cattle with the former more prevalent. Infection prevalences in cattle varied between 0 and 25% (median: 22%).
