摘要
在玉米-大豆浓缩蛋白型低寡糖基础日粮中分别添加0,0.50%,1.00%或2.00%的水苏糖制剂,研究不同添加量水苏糖对肉仔鸡消化器官发育及肠黏膜形态的影响。选用192只1日龄AA肉公鸡,随机分成4个处理组,每个处理设6个笼(重复),每笼8只鸡。结果表明:水苏糖的添加可不同程度地增加肉仔鸡消化器官的绝对重量,对盲肠和结直肠的作用效果尤为明显。添加0.50%水苏糖制剂对肉仔鸡的肠黏膜形态产生有利的影响,十二指肠、空肠和回肠的绒毛高度以0.50%水苏糖制剂添加组为最大;空肠和回肠的隐窝深度以0.50%水苏糖制剂添加组为最小;空肠和回肠的V/C值以0.50%水苏糖制剂添加组为最大。
An experiment was conducted to investigate the effects of gradient dietary stachyose on the development of digestive organ and the intestinal morphology in broilers.A total of 192 1 day-old male Arbor Acre broilers were randomly allotted into 4 treatments of 6 cages which contained 8 birds and were fed one of the 4 diets with stachyose preparation（STP） added to an oligosaccharide-low basal diet of corn-SPC at the dosage of 0,0.50%,1.00% and 2.00%,respectively.The results indicated that supplemental STP increased absolute and relative weight of digestive organs in broilers to various extents,especially for the caecum and the colon-rectum,and the inclusion of 0.50% STP had a positive effect on the mucosal morphology with maximum villus height in duodenum,jejunum and ileum,minimum crypt depth in jejunum and ileum and maximum V/C values in jejunum and ileum.
