摘  要：
将240只1日龄罗斯(ROSS 308)肉鸡分为4个组:处理组1(对照组)饲用基础日粮+金霉素,处理组2饲用基础日粮+枯草芽胞杆菌,处理组3饲用基础日粮+丝兰提取物,处理组4饲用基础日粮+丝兰提取物和枯草芽胞杆菌,以研究丝兰提取物和枯草芽胞杆菌对肉鸡生长性能的影响,试验期42 d。结果:平均日增重和料重比指标,处理组4肉鸡显著优于处理组1(P<0.05),而处理组2和3之间无显著差异(P>0.05)。肉鸡21日龄时,处理组4肉鸡血清白蛋白浓度显著大于处理组1;处理组4血清尿酸浓度显著小于处理组1。42日龄时,处理组2和4肉鸡的血清白蛋白浓度显著大于处理组1。本试验证明丝兰提取物与枯草芽胞杆菌均能提高肉鸡对饲料蛋白的代谢利用率,且具有协同改善肉鸡生长性能的效果。

摘  要：
New born broilers(ROSS 308) of 240 were assigned four groups to study the effect of yucca extracts and Bacillus subtilis feed additive on growth performance and blood chemistry in broilers.The broiler feed additives of Group 1 to 4 were aureomycin,Bacillus subtilis,yucca extracts,and the combination of Bacillus subtilis and yucca extracts.In the experimental period of 42 days,the average daily gain and feed efficiency(ratio of feed intake to body weight gain) of Group 4 broilers were superior to Group 1(P<0.05),and those of Group 2 and 3 broilers were no differences(P>0.05).At age of 21 d,the serum albumin concentration of Group 4 was higher than that of Group 1,and the serum uric acid concentration of Group 4 was lower than that of Group 1.At age of 42 d,the serum albumin concentrations of Group 2 and 4 were higher than that of Group 1.These findings proved that yucca extracts and Bacillus subtilis had the synergism of improving broiler growth performance by enhancing the feed protein metabolic utilization.
