摘 要:探讨不同饲养方式对藏鸡生产性能和脂肪代谢的影响,选用120只商品代健康雏鸡,按常规饲养管理规程,平均分成2组,一组笼养,另外一组放养。每个组5个重复,每个重复12只鸡。试验结果表明,饲养方式对藏鸡体重与日增重有显著影响,不论公鸡还是母鸡,笼养的体重与日增重都显著高于散养鸡(P<0.05)。笼养鸡的肌间脂肪、皮下脂肪、腹脂率、肌内脂肪含量均显著高于散养鸡(P<0.05)。The effects of different feeding methods on the production performance and fat deposition of Tibet chicken were discussed. 120 healthy commercial chicken were selected and fed according to the conventional feeding and management regulations. And the chicken were divided into two groups,one of which was raised in cage and another in freedom,with five repetitions in each group and with 12 chicken in each repetition. The results showed that the feeding methods had significant effects on the body weight and daily weight gain of Tibet chicken. The body weight and daily weight gain of both male and female Tibet chicken in cage were significantly higher than randomly-rearing chicken(P0.05) . The intermuscular fat,subcutaneous fat,the percentage of abdominal fat,the content of intramuscular fat in cage-rearing chicken were significantly higher than that of randomly-raised chicken(P0.05).
