| 摘 要： | 育肥猪肠道疾病问题是当前规模化猪场最常见的问题之一,其病因复杂导致防控难度增加,常见发病原因分为病原性因素与非病原性因素两种。病原性因素如病毒、细菌、寄生虫等;非病原性因素如生产管理、饲料营养、应激等外部环境引起。在我国当前的养殖环境下,病原性因素引起的猪肠道疾病占据大多数,常见的导致育肥猪腹泻的疾病的病原微生物如细胞内劳森菌(引起猪回肠炎)、猪密螺旋体痢疾、大肠杆菌、沙门氏菌、寄生虫及部分病毒性疾病等的感染在我国的猪场广泛存在,这些病原微生物会导致育肥猪群发生急性或慢性消耗性腹泻,使育肥猪发生成活率降低、饲料报酬下降、生长速度减缓、僵猪和残次猪比例升高等情况,给生长育肥猪的正常生长和出栏造成了很大的危害。文章通过对育肥猪肠道疾病的发病原因、发病特点与危害以及防控等方面进行了简要的阐述,以供参考。

| Abstract: | The intestinal disease of fattening pigs is one of the most common problems in large-scale pig farms at present. The causes of these diseases are so complex that it is difficult to prevent and control, and the common factors can be divided into pathogenic factors such as viruses, bacteria, parasites, and the non-infectious factors such as production management, feed nutrition, stress and so on.In the current breeding environment of our country, the infectious factors dominate, common diseases leading to diarrhea in fattening pigs such as pig enteritis, pig dysentery, Escherichia coli, Salmonella, parasites and some viral diseases. The pathogenic miscroorganisms can lead to acute or chronic consumptive diarrhea of fattening pigs, lower survival rate, lower feed reward, slower growth rate, higher proportion of stiff pigs and residual pigs, etc. It has caused great harm to the normal growth and column of fattening pigs. This paper briefly describes the causes, characteristics, hazards and prevention and control of intestinal diseases in fattening pigs for your reference. |
