柠檬酸对三黄土鸡早期生产性能的影响

用海大香特1号三黄土鸡雏鸡进行饲养试验，对添加0．3％、0．5％、0．7％柠檬酸饲养的试验组和不添加柠檬酸饲养的对照组进行体增重、采食量、料肉比等生产性能的比较，试验结果表明：添加0．3％柠檬酸试验组的三黄土鸡早期体增重，显著高于对照组，同时也高于添加0．5％、0．7％柠檬酸的试验组；添加0．3％柠檬酸试验组的料重比、成活率也优于其他试验组。

The Effect of Citric Acid on the Performance of Three Yellow Chicken

Three yellow chicken from poultry breeding centre of ZJOU were selected to do feeding experiment.During the experiment,the chickens were fed with the basal diets added to 4 levels of citric acid (0%,0.3%,0.5%, 0.7%).Comparison on daily gain,feed consumption,feed to gain ratio and survival rate of 4 levels were studied in this paper.The result shows that daily gain can be significantly increased in the test group with 0.3% citric acid.There is no significant difference between others.The feed to gain ratio and survival rate are higher in the test group with 0.3% citric acid than other groups.
