肉牛疾病防制的措施

疾病问题是阻碍肉牛业发展的重要问题。肉牛在养殖生产的过程中,比较容易患传染病、寄生虫病、产科和内科等疾病。如果牛群饲养员对牛舍内部和牛群的活动空间卫生管理不到位,牛群最容易患上腐蹄病和产科疾病。众所周知,传统牛群的饲养是为了农业发展,将牛群应用到田地等役用之中,现在的牛群饲养则是为了人类饮食,摄取丰富的营养。在这种牛群饲养新形势下,牛群大规模的圈养,使得牛群在生长中容易产生一些少见的疾病,如侵袭性疾病和营养性疾病。而现在对牛群饲养方式的不规范性和不确定性,导致牛群管理上混乱,牛群交流频繁,疫病扩散快。

规模化养猪场疾病防制探讨

随着改革开放和经济的发展,传统的养猪模式已向规模化密集型转变,饲养数量和规模越来越大。嘉定区的养猪业经过近十多年的发展,规模化、密集型饲养已成为主要的养殖方式。据统计,全区千头猪场有50多个,5000头以上的猪场有20多个,万头以上的猪场有6个,全区年上市商品猪45万头左右,其中规模猪场占60％左右。从疾病防制方面来说,由于大多规模场实行高密度饲养,其劳动生产率较高,在管理方面造成饲养员和兽医技术人员对猪的群体观察多,个体观察少,因而对疾病的尽早发现、尽早治疗带来了难度。抓好规模猪场的疾病防制是关系到养猪生…

Respiratory diseases of beef cattle under intensified systems

Extract

Under intensified management systems, the more common diseases of beef cattle include pasteurellosis or shipping fever, infectious bovine rhinotracheitis (IBR), enzootic or virus pneumonia, and bovine diphtheria. Other respiratory diseases that might be prevalent in the beef management systems of New Zealand include lungworm, atypical interstitial pneumonia, and allergic rhinitis. These will be discussed only in terms of differential diagnosis. No further mention will be made of the exotic diseases contagious bovine pleuropneumonia and haemorrhagic septicaemia or to the respiratory form of bovine tuberculosis which is uncommon in both Canada and New Zealand.

Dwarfism in beef cattle: Diagnosis and control

Abstract

Extract

In a previous publication dealing with the active immunity of mice to Salmonella typhimurium, it was shown that, by varying the interval of time between vaccination and challenge, two phases of increased resistance were observed (Jonas, 1967a Jonas, W. E. 1967a. Studies on the immunological aspects of salmonellosis of mice. Active immunity. N.Z. vet. J., 15: 27–30. [Taylor &; Francis Online] , [Google Scholar]). Phase I resistance occurred from 3 to 11 days after vaccination and phase II from 15 to 21 days.

The reported use of drugs to prevent diseases in beef cattle in Tennessee

The National Animal Health Monitoring System (NAHMS) (Round 2) for Tennessee collected baseline data on the preventive (as opposed to therapeutic) use of drugs from 60 beef cow-calf herds selected by a random, stratified, two-stage sampling plan. Counties were selected randomly with replacement for three herd-size strata, and herds were selected within countries by an area-frame method. Data were collected during monthly interviews for 1 year (1987–1988).

Tennessee beef cattle were medicated with 31 drugs to prevent diseases. The drugs most frequently used were anthelmintics and insecticides. The diseases against which preventive drugs were most frequently used were external parasites, intestinal parasites, ‘pink eye’ (keratoconjunctivitis), anaplasmosis, and respiratory infections. Ivermectin was the most frequently used anthelmintic and the most frequently used drug. Levamisole, fenbendazole, and thiabendazole were also frequently used anthelmintics. The most frequently used insecticides were the organophosphates (including fenthion, dichlorvos, and stirofos). Antimicrobials seldom were used, suggesting that prophylactic antimicrobial use in Tennessee beef cattle may not be a major public-health concern.
