摘　　要：为研究不同枯草芽孢杆菌产品对科宝肉鸡生长性能的效果,试验选用1日龄科宝肉仔鸡204羽,随机分成3个处理组,4个重复,每个重复17羽,分别饲喂基础日粮(对照组)、基础日粮+枯草芽孢杆菌A、基础日粮+枯草芽孢杆菌B。试验组肉鸡日粮中芽孢数为600万个·g^(-1)。试验过程中分别于肉鸡1、14、28和42日龄时全群称重,并全程记录每重复肉鸡鸡群每天采食情况、死淘鸡只数及重量。试验结果表明,添加枯草芽孢杆菌能提高肉鸡日增重,降低料肉比。其中基础日粮+芽孢杆菌B组肉鸡的应用效果最好、最稳定,体重和日增重都比对照组显著提高(P<0.05),提高2.64%,料肉比在前两周较对照组显著降低,最终肉鸡养殖收益可提高0.37元·只^(-1),收益率相对于对照组提高了8.31%。This trial mainly studied the effect of Bacillus subtilis preparation on the growth performance of KEBAO broilers.Different Bacillus subtilis preparation was collected at the market,to study different effect on the growth performance of broilers.Two hundred and four one-day-old broiler chicken of KEBAO was selected in the trial,and they were divided into three groups,each group with four duplicates,and every duplicate with seventeen chickens.The control group was fed with basic diets.The trial group was fed with basic diets supplemented with Bacillus subtilis preparation of Kangdien,the trial two group was fed with basic diets supplemented with Bacillus subtilis preparation of Keruo.In the two trial groups,the number of Bacillus subtilis is six million per gram.During the trial,all the broiler chicken were weighed on the first day,14-th day,28-th day and 42-th day respectively and every duplicate's daily diets,numbers and weight of death and eliminated chicken werere corded.The trial results showed that Bacillus subtilis added in the trial group could improve the daily weight gain,lower the feed conversion rate.In the trial,the broiler chicken which adds Bacillus subtilis of Keruo had the best and the most stable effect.The body weight and daily weight gain of the Keruo group was 2.64%higher than the control group(P<0.05).The Feed conversion rate was significantly lower than the control group in the first two weeks(P<0.05).The Breeding efficiency of every broiler chicken can im prove 0.37 yuan.The Yield of Keruo group was higher than the control group about8.31%.
