摘要: 本文用益生素饲喂肉鸡,八周龄屠宰后,取小肠粘膜上皮细胞、肝细胞作透射式电镜观察,发现试验组鸡细胞粗面内质网网腔扩大,数量增多,并紧围于线粒体四周。滑面内质网、高尔基复合体数量增多,核仁数增加。小肠粘膜上皮细胞微绒毛长度增长。肝细胞大量核糖体聚集,糖原增加,大量肝细胞微绒毛伸入血窦。研究表明上述细胞蛋白质、脂肪合成功能增强,肠粘膜上皮细胞吸收功能增强,肉鸡生长性能改进。

Abstract: A probiotics get from Sichuan Angricultrual University was fed to the broilers. The broilers were killed at the age of 8 weeks. The epithelial cells of small intestinal mucosa and hepatic cells were sampled for transmission electron microscope observation. Compared with the controls, it was found that the cavaties of rough endoplasmic reticula were enlarged, the number of which was increased, and encircled mitochondrons closely. The quantities of smooth endoplasmic reticula and the Golgi bodies were increased. The microvilli on the epithelial cells of small intestinal mucosa were longer. Much microvilli of the epitheliel cells of small intestinal mucosa inserted into hepatic sirusoids, and much vibosomes gathered there. It was concluded from above that the improvement of broiler performances owing the the probiotics were probably related to that the probiotics accelerated the synthetic metabolism of protein and fat in cells, and improved the absorption of small intestinal mucosa.
