本文旨在研究冻干粉剂型乳酸菌对肉鸡生产性能的影响。随机选取健康的肉鸡分组进行乳酸菌喂养试验，观察其对平均日增重、料肉比、成活率的影响。饲喂冻干粉剂型乳酸菌试验组肉鸡的平均日增重可达68.67g，显著高于对照组（P<0.05）。冻干粉剂型乳酸菌对肉鸡日增重具有显著效果，可降低肉鸡的死亡率和料肉比。%The paper aimed to study the effect of lactobacillus freeze-dried powder on the performance of broilers. Healthy broilers were selected randomly, related parameters of feeding experiment in terms of average gain of weight, ratio of feed/gain and survival rate were observed. Results revealed that average gain of weight of group feeding with lactobacillus could reach 68.67 g, which was significantly higher than control group ( P<0.05). The lactobacillus freeze-dried powder exerts a significant effect on improving the average gain of weight and plays a vital role in reducing the mortality rate and feed/gain ratio of broilers.
