【摘要】 将500只1日龄艾维茵肉鸡随机分为5组,即分别饲喂添加80、120和200g/kg大豆活性肽的日粮、添加抗生素的日粮和基础日粮。在28、49日龄取材,采用组织切片及组织化学染色方法检测肉鸡十二指肠、空肠、盲肠的绒毛长度与隐窝深度比值、杯状细胞数量,观察大豆活性肽对肉鸡肠道黏膜结构的影响,进而研究大豆活性肽对肉鸡消化能力的作用。结果表明:日粮中添加80￣120g/kg的大豆活性肽能够提高肉鸡生长初期的肠道杯状细胞数量,增加肉鸡肠道绒毛长度/隐窝深度比值。更多还原

【Abstract】 A total of 500 One-day-old broiler was randomly assigned to five groups: fed with basal diet supplemented with 80、120 and 200 g/kg soybean peptide, antibiotic、basal diet respectively. The goblet cells and the ratio of length villous to intestinal crypt (V/C) of broiler duodenum, jejunum and cecum was observed by H&E or histochemistry staining when broilers were 28 and 49 day old. Results suggested that 80~120 g/kg soybean peptide could increase the number of goblet cells and the V/C of broiler intestine.更多还原
