摘　　要：该试验旨在研究鲤(Cyprinus carpio)的饲料中添加不同水平的地衣芽孢杆菌(Bacillus licheniformis)对其生长性能的影响,确定鲤养殖中最适地衣芽孢杆菌添加水平。试验选择480尾体重相近的鲤随机分成4个处理组,每组4个重复,每个重复30尾。各组鲤依次投喂含有0%、0.1%、0.2%和0.4%地衣芽孢杆菌的饲料。驯养2周,进行60 d的正式试验。试验结束测定各组鲤的生长性能。结果显示,与对照组比较,试验组投喂含0.2%和0.4%地衣芽孢杆菌的饲料,可以显著提高其试验末重、增重率,显著降低了饲料系数(P<0.05);投喂含有0.1%、0.2%和0.4%地衣芽孢杆菌的饲料,可以显著提高特定生长率(P<0.05);投喂含有0.2%地衣芽孢杆菌的饲料可以显著提高蛋白质效率(P<0.05)。研究结果表明,在鲤的养殖中添加适量的地衣芽孢杆菌可以明显改善其生长性能,且地衣芽孢杆菌的最适添加量为0.2%。This experiment was designed to study the effects of adding different levels of Bacillus licheniformis to the feed of carp(Cyprinus carpio)on its growth performance,and to determine the optimal level of Bacillus licheniformis addition in carp culture.In the experiment,480 carp with similar body weight were randomly divided into 4 treatment groups,with 4 replicates in each group and 30 carp in each replicate.The carp in each group were sequentially fed diets containing 0%,0.1%,0.2%and 0.4%Bacillus licheniformis.A 60 d formal trial was conducted after 2 weeks of domestication.At the end of the trial the growth performance of the carp in each group was determined.The results showed that,compared with the control group,the experimental group fed diets containing 0.2%and 0.4%Bacillus licheniformis could significantly increase their end-of-trial weight,weight gain rate,and significantly reduce the feed coefficient(P<0.05);feeding diets containing 0.1%,0.2%,and 0.4%Bacillus licheniformis could significantly increase the specific growth rate(P<0.05);feeding feeds containing 0.2%Bacillus licheniformis could significantly increase the specific growth rate(P<0.05);and feeding diets containing 0.2%Bacillus licheniformis could significantly increase the specific growth rate(P<0.05).Bacillus licheniformis significantly(P<0.05)increased protein efficiency.The results of the study indicated that the addition of appropriate amount of Bacillus licheniformis in the culture of carp can significantly improve its growth performance,and the optimal amount of Bacillus licheniformis is 0.2%.
