摘　　要：为了解大栏微生物发酵床养猪对育肥猪抗病力的影响,将60日龄左右体重相近的"杜×长×大"商品猪2 000头随机等分为试验组和对照组。试验组采用大栏发酵床饲养方式,对照组采用常规水泥地板饲养方式进行育肥,其他饲养管理条件一致,试验期120d。试验结束时,试验组和对照组各随机抽取6头猪空腹采集血样检测。检测结果发现,试验组的血清碱性磷酸酶活性比对照组提高0.86%(P>0.05),丙氨酸转移酶活性降低33.8%(P<0.01),血清尿素氮含量降低39.8%(P<0.01),总胆固醇含量增加9.4%(P<0.05),总胆红素增加36.4%(P>0.05),血糖降低41.4%(P<0.01);IgA(g·L-1)含量增加34.05%(P<0.01),IgG(g·L-1)含量提高21.6%(P<0.01),IgM(g·L-1)含量提高17.3%(P<0.05);猪瘟抗体效价比对照组增加37%(P<0.05)。结果表明大栏微生物发酵床饲养方式,可以改善猪体内的糖、蛋白质和脂肪的代谢,降低猪的应激,提高猪的免疫力,增强抗病能力。'Duroc× Landrace×Yorkshire'commodity pigs around the age of 60 days were raised in the cement floor pigsty(control group)and microbial fermentation bed pigsty(experimental group),respectively,to feed for 120 d.At the end of the experiment,the experimental group and the control group were collected from 6pig blood tests.The results showed that,serum alkaline phosphatase activity in experimental group increased by 0.86%than that of control group(P>0.05),decreased 33.8% enzyme activities of alanine transfer(P<0.01),serum urea nitrogen content decreased by39.8%(P<0.01),the total cholesterol content increased by 9.4%(P<0.05),total bilirubin increased 36.4%(P>0.05),blood glucose reduced by 41.4%(P<0.01);IgA(g·L-1)were increased by 34.05%(P<0.01),IgG(g·L-1)was increased by 21.6%(P<0.01),IgM(g·L-1)increased by 17.3%(P<0.05);swine fever antibody titer than that of the control group increased more than 37%(P<0.05).The results showed that the large scale microbialfermentation bed feeding mode,can improve the pigs of sugar,protein and fat metabolism,reduce the porcine stress,improve the immunity of pigs,enhance the capacity of resistance.
