Effects of Compound Chinese Herbal Medicine on Production Performance and Intestinal Structure of Weaned Piglets

研究了复方中草药添加剂对断奶仔猪生产性能和肠道形态结构的影响,结果表明:试验ⅡⅢ和Ⅳ组均能一定程度提高断奶仔猪的日平均采食量,促进仔猪的生长速度,且试验Ⅳ组效果最好;试验Ⅱ,Ⅲ和Ⅳ组的各肠段绒毛长与隐窝深度与对照组差异均极显著(P<0.01),且试验Ⅳ组的十二指肠、回肠和试验Ⅲ组的空肠绒毛高度显著高于试验Ⅱ(P<0.05);对于绒毛高度与隐窝深度的比值而言,试验Ⅱ,Ⅲ和Ⅳ组均比对照组增大,其中试验Ⅱ组的空肠和试验Ⅲ组的十二指肠、回肠差异达到显著水平(P<0.05)。

The effects of compound Chinese herbal medicine additive on the production performance and intestinal structure of weaned piglets were studied.The results showed that the test group IV had the best effect,and the test group II,III and IV could enhance the daily feed intake to a certain extent,and promote the growth speed of piglets.The intestinal villus length and intestinal recess depth of piglets in test group II,III and IV were significantly different from those of CK（P0.01）,The villus height of duodenum and ileum in group IV,as well as the villus height of jejunum in group III were significantly bigger than those of group II（P0.05）.As compared with CK,the ratio of the villus height to recess depth of piglets in test groups was increased,and there were significant differences in jejunum between group II and CK,and in duodenum and ileum between group III and CK（P 0.05）.
