摘要
为研究瘤胃源益生菌菌粉（BPR）对雪山鸡生长性能、屠宰性能与激素分泌的影响,选择1日龄健康雪山鸡234只,公母各半,随机分成3组.对照组饲喂基础日粮,试验1、2组分别在基础日粮中添加0.5％、1％ BPR.结果表明,1～20日龄时,与对照组相比,试验1、2组平均日采食量极显著降低（P＜0.01）;20～42日龄时,与对照组相比,试验1组平均日采食量显著降低（P＜0.05）,平均日增重试验1、2组显著升高（P＜0.01）,饲料转化率显著降低（P＜0.01）;1～42日龄时,与对照组相比,试验1、2组平均日采食量分别降低1.63％（P＜0.01）、0.80％（P＜0.05）,平均日增重显著升高（P＜0.01）,饲料转化率显著降低（P＜0.01）;公鸡屠宰率显著提高（P＜0.01）,公母合并试验2组提高2.60％（P＜0.05）;与对照组相比,试验2组四碘甲酰原氨酸（T4）含量极显著升高（P＜0.01）,胰岛素（Ins.）含量显著升高（P＜0.05）.综上,BPR能显著改善雪山鸡血清中T4和胰岛素水平及其生长和屠宰性能.
The experiment was conducted to investigate the effects of bacteria powder separated from rumen （BPR） on growth performance,slaughter performance and hormone secretion in Xueshan chicken. A total of 234 one-day-age Xueshan chickens were randomly divided into 3 groups, in which the male and female were 50% respectively. The control group were fed with basal diets. The experimental group 1,2 were fed with basal diets supplement with 0.5%,1% BPR respectively. The results showed that compared with control group,average daily feed intake at 1 to 20 days of age was significantly decreased （P〈0.O1）for group 1 and 2;At 20 to 42 days of age,average daily feed intake of experiment group 1 decreased significantly （P〈0.05）,the average daily gain of experimental group 1 and 2 were sig- nificantly increased （P〈0.01）and the feed conversion ratio decreased significantly （P〈0.01）;At 1 to 42 days of age, compared with the control group,the average daily feed intake of group 1 and 2 decreased by 1.63% （P〈0.01）,0.80% （P〈0.05） respectively, the average daily gain of experimental group 1 and 2 increased significantly （P〈0.01） and the feed conversion ratio decreased significantly （P〈0.01）;For the slaughter rate,male of experimental group 1 and 2 increased significantly（P〈0.01）,the merger of experimental group 2 increased by 2.60% （P〈0.05）;The endogenous hormones T4 and Ins. of experimental group 2 increased by 43% （P〈0.01）,22.02%（P〈0.05）,respectively. Above all,BPR could significantly increase the hormone T4 and Ins. concentration levels,growth performence and slaughter performence of Xueshan chicken.
