红酒香菇多糖对肉鸡生长性能及抗病力的影响

[目的]探讨红酒香菇多糖对肉鸡生长性能及抗病力的影响。[方法]选用1日龄AA肉鸡180只,Ⅰ组从第7天开始在日粮中添加2%的红酒香菇多糖,Ⅱ组为对照组,2组鸡分别于14、28和49日龄采血测定血液中HI抗体水平并检测红酒香菇多糖对免疫器官和生长发育的影响。[结果]日粮中添加2%的红酒香菇多糖能显著提高肉鸡的生长性能和饲料转化效率。试验组在14、28和49日龄体重分别提高了10.49%、13.66%和8.35%,平均日增重提高了8.49%,料肉比下降了5.29%。日粮中添加2%的红酒香菇多糖能显著促进肉鸡的胸腺、法氏囊和脾脏等免疫器官的发育,增强免疫效果,使机体产生高而强的抗体。[结论]该研究为开发新的功能性饲料添加剂和促进肉鸡产业的发展奠定了基础。

Effect of Red Wine Lentinan on the Growth Performance and Disease Resistance of Broilers

[Objective] The aim was to discuss the effect of red wine lentinan on the growth performance and disease resistance of broilers.[Method] 180 1-day-old AA broilers were selected.2% red wine lentinan was added into diet of Ⅰgroup from the beginning of 7 d and Ⅱgroup was control.Blood sampling of 2 group broilers were taken when they were 14,28 and 49-day-old,the HI antibody level in the blood were detected and the effects of red wine lentinan on the immune organs and growth were detected.[Result] Adding 2% red wine lentinan into diet could improve the growth performance and feed conversion efficiency of broilers.The body weight of experimental group were increased 10.49%,13.66% and 8.35%,resp.when the broilers were 14,28 and 49-day-old,average daily gain was increased 8.49% and feed conversion ratio was decreased 5.29%.Adding 2% red wine lentinan into diet could promote the development of broiler immune organs such as thymus,bursa of fabricius and spleen,improve the immune effect and make the body produce high and strong antibody.[Conclusion] The research laid the foundation for the exploitation of new functional feed additive and the promotion of the development of broiler industry.
