摘要：

通过养殖试验，比较了发酵床不同垫料配比对肉鸡生长性能及鸡舍环境的影响。按照总重量相同原则，试验共设5个处理，分别为：常规垫料(CK)、70%常规垫料+30%玉米秸秆(30% S)、40%常规垫料+60%玉米秸秆(60% S)、10%常规垫料+90%玉米秸秆(90% S)、20%常规垫料+60%玉米秸秆+20%沸石(60% S+20% Z)。结果表明：（1）试验期间各试验组平均日增重、平均日耗料、料肉比均差异不显著(P＞0.05)；但处理30% S料肉比最低、死淘数最少；（2）各处理垫料含水率和氨浓度随肉鸡的生长逐渐升高，其中30% S处理含水率比CK降低了12.91%，平均氨浓度比CK降低了7.96%。综合判断，本试验条件下常规垫料和玉米秸秆按30% S混合作垫料饲养肉鸡最为适宜。

Abstract:

A pile experiment was carried out on broilers feed farm, to research on the effects of different litter ratio on growth performance of broilers and on environment in chicken coops in Deep-litter System. For the same total mass of each treatment, 5 treatments were carried out: traditional litter (CK), 70% traditional litter+30% corn straw (30% S), 40% traditional litter+60% corn straw (60% S), 10% traditional litter+90% corn straw (90% S), 20% traditional litter+60% corn straw+20% zeolite (60% S+20% Z). The results showed that: (1) there were no significant differences in average daily gain (ADG), average daily feed intake (ADFI), feed to gain ratio (F/G) among all treatments (P>0.05); but 30% S had lower feed to gain ratio (F/G) and death number than other treatments; (2) the moisture content and the concentration of NH3 rose gradually during the broilers growth. The moisture content of 30% S lower 12.91% than CK, the average concentration of NH3 lower 7.96% than CK.
