中文摘要：

试验研究了益生素和抗菌肽联合应用对肉鸡生长性能、肉品质和鸡舍氨气浓度的影响。选用AA肉仔鸡1600只，随机分成4个处理，每个处理5个重复，每个重复80只鸡。4个处理分别为对照组（C）、抗生素组（T1）、微生态制剂组（T2）、微生态制剂和抗菌肽组（T3）。试验期49d，试验结束时测量肉品质。试验结果表明，益生素和抗菌肽联合应用可以提高肉鸡的日增重，降低料重比，提高屠宰率并改善肉品质，降低鸡舍中氨气浓度。

英文摘要：

To evaluate the effect of probiotics and antibacterial peptide on growth performance, quality of meat and henhouse ammonin gas of broilers, one thousand and six hundred AA broilers were randomly assigned to four groups, five repeat in each group, and 80 chickens for each repeat. Four groups were control group（C）, antibiotics group（T1）, probiotics group（T2）, antibiotics and probiotics group（T3）. Trial period was 49 days; quality of meat was analyzed at the end of the study. The results indicated that antibiotics and probiotics combined application could in- crease daily weight gain and dressing percentage, decrease feed conversion ratio and the concentration of ammonin gas in henhouse, improve quality of meat.
