摘要
某些抗生素对反刍动物的生长有促进作用 ,对其中的机理尚未阐明。可能的解释是这些抗生素选择性地杀灭某些瘤胃微生物 ,而这些微生物的代谢产物或微生物自身能够刺激消化道组织的蛋白质代谢 ,降低了蛋白质和能量的利用效率。本试验用大剂量(Floodingdose)方法测定了未处理和黄霉素处理绵羊的消化道组织和粘膜的蛋白质合成速率。结果表明 ,处理绵羊瘤胃、十二指肠、空肠、回肠、盲肠、直肠组织的蛋白质合成速率均低于未处理绵羊 ,但十二指肠、空肠、回肠粘膜的蛋白质合成速率则是试验组高于对照组 ,证实了黄霉素对消化道组织的蛋白质代谢强度有影响。
The protein FSR of gastrointestinal tissue,and mucosa of sheep treated by flavomycin and untreated were measured by flooding dose procedure in order to observe if flavomycin treatment could change the protein synthesis or not.The results indicated that FSR of the duodenal,jejunum,ileum,caecum,and colon were depressed by flavomycin treatment.FSR of the duodenal and jejunum mocosa was higher in flavomycin treated sheep than the control,while that of the ileum mucosa was lower.The results of present study suggest that flavomcin may have its growth improving effect on ruminant through influence the metabolism of tissues of the animal.
