蜂花粉对肉鸡消化腺发育的影响

Effect of bee pollen on the development of digestive gland of broilers

选择1日龄AA肉仔鸡144只,随机分为2组,每组72只。对照组饲喂玉米豆粕型基础日粮,试验组添加1.5%蜂花粉,试验期42d。分别于1,2,3,4,5和6周龄每组随机抽取试验鸡6只,取小肠、肝、胰腺称重并制作切片。结果:试验组肝、胰腺的平均重量和相对重量均高于对照组,部分周龄差异显著(P<0.05)或极显著(P<0.01)。试验组鸡肝细胞、肝血窦结构清晰,枯否氏细胞体积较大;胰腺的腺泡较大,亮胰岛数量多、体积大;小肠腺的长度显著或极显著大于对照组。结论:蜂花粉能促进肉鸡肝、胰腺和小肠腺的发育。

One hundred and forty-four one day-old AA broilers were randomly divided into two groups, and fed with the basic diet supplemented with 0% and 1.5% bee pollen for 6 weeks. Six chickens in each group were randomly selected for dissection at every weekend. Small intestine, liver and pancreas were obtained, weighted and made into paraffin section. Compared with the control group of the same week-age, both of the average weight of liver and pancreas in the experiment group were higher, and some exhibited significance (P< 0.05) or extreme significance (P<0.01); The structure of hepatocyte and hepatic sinusoid were clearer; The Kupffer cell volume and gland alveolus of pancreas were bigger; The bright pancreas islet was more and bigger, and the length of small intestinal gland was significantly or extremely significantly longer. The results showed that bee pollen could promote the development of liver, pancreas and small intestinal gland of broilers.
