摘要
采用酶学反应方法,检测了增生性肠炎阳性猪与阴性猪的胰腺、十二指肠、空肠、回肠淀粉酶、胰蛋白酶、脂肪酶及碱性磷酸酶的活性变化。结果表明:(1)猪增生性肠炎阳性猪胰腺、十二指肠、空肠、回肠胰蛋白酶活性同比阴性猪均下降,其中空肠、回肠的同比差异显著(P<0.05);(2)阳性猪回肠碱性磷酸酶活性显著下降(P<0.05),胰腺、十二指肠、空肠碱性磷酸酶活性与阴性猪相比差异不显著(P>0.05);(3)阳性猪胰腺、十二指肠、空肠、回肠的淀粉酶和脂肪酶活性均下降,但差异不显著(P>0.05)。猪增生性肠炎病猪空肠、回肠胰蛋白酶以及回肠碱性磷酸酶活性显著降低,酶活性降低引起了增生性肠炎猪消化机能障碍。
The enzyme activities of amylase,trypsin,lipase and alkaline phosphatase in pancreas,duodenum,jejunum and ileum were detected in the swine of porcine proliferative enteritis by enzymatic reaction method.The results show as follows.（1） Compared with the negative swine,the activity of the trypsin in pancreas,duodenum,jejunum,and ileum of the positive swine all decreased,among them the difference of comparison in jejunum and ileum is significant（P0.05）;（2） Compared with the negative swine,the activities of the alkaline enzymes in ileum are significant（P0.05）,and no obvious difference in pancreas,duodenum,and jejunum（P0.05）;（3） The activities of amylase and the lipase in pancreas,duodenum,jejunum and ileum have no obvious difference between the positive and negative swines（P0.05）.These results suggest that the activity of trypsin in jejunum,ileum and alkaline enzymes in ileum decreased significantly.The decrease of enzyme activities could led to disor-der of digestion in the swine of porcine proliferative enteritis.
