发酵床不同垫料配比对肉鸡生长性能及鸡舍环境的影响

Effects of Different Litter Ratio on Growth Performance of Broilers and on Environment in Chicken Coops in Deep-litter System

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。

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（P0.05）;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.
