摘　　要：本文旨在研究不同益生菌制剂对黄羽肉鸡生长性能、屠宰性能和肉品质的影响。试验选用1日龄黄羽肉鸡180只,随机分成3组,每组3个重复,每重复20只,对照组饲喂基础日粮,试验组在基础日粮中分别添加0.1%益生菌、0.1%加酶益生菌,试验周期为17周。结果表明:在基础日粮中添加不同益生菌制剂均能显著提高黄羽肉鸡的生产性能,不仅提高日增重和料重比(P<0.05),而且屠宰率、全净膛率、半全净膛率、胸肌率和肌肉的p H值有显著提高(P<0.05),同时降低黄羽肉鸡腹脂率(P<0.05),但组间肌肉剪切力、失水率、干物质、肌间脂肪和蛋白质差异均不显著(P>0.05)。由此可见,益生菌制剂能显著提高黄羽肉鸡的生产性能,对屠宰率、全净膛率、胸肌率、腹脂率以及肉品质中的p H值均有显著影响。To study the effects of different probiotic-preparation on growth performance,slaughter performance and meat quality of yell0w-feathered broiler, 180 healthy one-day-age yellow-feathered broilers were chosen and randomly divided into three groups, each group had three repeats, and each repeat had 20 chickens. Control group were fed with basal diet, while tested groups were fed with basal diet supplemented with 0.1% probiotic and enzymatic probiotie, respectively. The test lasted for 17 weeks. The results showed that compared with the control group,adding probiotic and enzymatic probiotic could raise average daily gain and the rate of feed to gain, respectively （P〈0.05）,and the dressing percentage,the eviscerated yield rate,the semi-eviscerated yield,breast rate and the meat pH（P〈0.05）,but decrease abdominal fat percentage （P〈0.05）, while there were no significant difference between tests groups. There were no significant difference among groups in muscle shear force, water loss rate, dry matter, intermuscular fat and protein. The resuhs indicated that adding different probiotic-preparation could significantly improve growth performance,slaughter performance and meat quality of yellow-feathered broiler.
