摘要
目的:研究有机硒对动物胸腺和腔上囊的平均重量、器官指数和组织结构发育的影响。方法:取1日龄闽中麻鸡396羽,随机分为4组,对照组(A组)饲喂基础日粮,试验组(B、C、D组)分别在基础日粮中添加中药富硒酵母2、34、g/kg,试验期49 d。每周末各组随机取鸡6羽,称重后处死取胸腺和腔上囊,称重,Bouin液固定,制作石蜡切片,显微观察,摄影。结果:B、C、D组的胸腺和腔上囊平均质量和器官指数均高于A组,部分差异显著(P<0.05)或极显著(P<0.01)。D组鸡胸腺小叶增大,皮质增厚,胸腺小体减少;C组腔上囊皱襞发达,腔上囊小结体积较大,皮质较厚,退化迟缓。结论:在动物基础日粮中添加中药富硒酵母能够促进动物胸腺和腔上囊的发育。添加0.201 mg/kg有机硒对腔上囊发育有明显的促进作用;添加0.268 mg/kg的有机硒对胸腺的发育有促进作用,延缓胸腺的退化。
Objective: To study the effect of se-enriched yeast cultured in Chinese medicine(SEYCCM) supplemented in diet on weight average,organ index and tissue structure growth of the thymus and the cloacal bursa in animal.Methods: A total of 396 one-day-old Min Zhong-ma chickens were divided randomly into four groups,the control group(group A) was fed with corn-soybean basal diet,and experiment groups(group B,C,D) were feed on the basal diet supplemented with(g/kg) 2,3,4 of SEYCCM for 49 days.The 6 chickens were ta...
