预防和控制动物疫病,疫苗免疫接种是有效手段之一,但是疫苗免疫接种能否取得最佳效果,不仅取决于接种时疫苗的用量、接种途径和免疫程序等外部因素,还取决于动物机体应急因素,因此,虽然对动物进行免疫接种,但不一定能产生较为理想的免疫效果。近年来,我县一些实施免疫过的动物也曾发生了传染病,给畜牧业生产造成一定的损失。根据工作实践的调查分析,引起动物免疫效果低下的因素及防制对策,归纳如下,供动物防疫工作第一线同仁们参考。
Prevention and control of animal diseases and vaccine immunization is one of the effective measures. However, the best effect of vaccine immunization depends not only on the external factors such as the amount of vaccination during vaccination, the route of vaccination and the immunization program, but also on the emergency of animal body Factors, therefore, although immunized animals, but not necessarily produce a more satisfactory immune effect. In recent years, some immunized animals in our county have also been infected with infectious diseases, causing some losses to livestock husbandry production. According to the investigation and analysis of work practices, factors that cause low immune effects in animals and their control strategies are summarized as follows, for the reference of the frontline colleagues for animal epidemic prevention.
