摘要

A 180 d feeding trial was conducted to evaluate the effect of different feeding modes on liver of Gushi chicken.The chickens from 1-day-old were fed in the warm house for 30 d,and then divided into four groups by different feeding modes(O-noant,outdoor without antibiotics;O-ant,outdoor with antibiotics;D-noant,indoor without antibiotics;D-ant,indoor with antibiotics),respectively,to evaluate the effect on liver.The results showed that different feeding modes significantly influenced the growth,liver weight,subcutaneous fat thickness,liver fat and liver free amino acid contents.The outdoor feeding without antibiotic reflected remarkably(P﹤0.05)low liver weight and fat content with normal morphology.While,other groups showed different levels of fat metabolism disorder in the liver.Based on chicken liver healthy,the outdoor feeding without antibiotic was the optimal feeding mode for Gushi chicken.
