摘要
试验旨在研究植物精油对蛋鸡生产性能、血清生化指标、免疫指标、肠道发育及肠道菌群的影响.选取430日龄金粉一号蛋鸡16万只,随机分为2组,每组5个重复,每个重复1.6万只鸡.CO组饲喂基础饲粮,EO组在基础饲粮中添加200 g/t植物精油.试验期40 d.结果显示,植物精油可以提高蛋合格率,降低料蛋比,显著提高蛋鸡血清中免疫球蛋白G和免疫球蛋白A含量(P＜0.05).植物精油降低了蛋鸡的小肠绒腺比,提高了肠道中乳酸杆菌数量,显著降低了肠道中产气荚膜梭菌数量(P＜0.05).研究表明,在饲粮中添加植物精油可以提高蛋鸡的生产性能和免疫力,促进肠道形态发育,降低有害菌数量.
Abstract
The purpose of this experiment was to study the effects of plant essential oils on the production performance,serum biochemical indexes,immune indexes,intestinal development,and intestinal flora of laying hens.A total of 160 thousand 430-day-old JF-1 laying hens were randomly divided into two groups,with five replicates in each group and 16 000 hens in each replicate.The CO group was fed with basal diet,while the EO group was fed with 200 g/t plant essential oil.The trial period was 40 days.The results showed that the qualified egg rate of laying hens was increased,the feed-to-egg ratio was decreased,and the serum IgG and IgA concentrations of laying hens were significantly increased(P＜0.05).Plant essential oil decreased the ratio of intestinal chorionic gland,increased the number of Lactobacillus in intestinal tract,and significantly decreased the number of Clostridium perfringens in intestinal tract(P＜0.05).The result shows that adding plant essential oil to the diet can improve the performance and immunity of laying hens,promote the development of intestinal morphology,and reduce the number of harmful bacteria.
