摘　　要：本试验旨在研究多菌种复合微生态制剂对蛋种鸡生产性能的影响。选用384只15周龄的海兰褐蛋种鸡,随机分成4组,每组4个重复,每个重复24只鸡。对照组饲喂基础日粮,试验1、2、3组在基础日粮中分别添加50、100、200 g/t的复合微生态制剂。结果表明,试验3组的平均蛋重显著高于对照组(P<0.05),但开产日龄比对照组晚;在27～30周龄时试验2组显著提高了产蛋率并降低了料蛋比(P<0.05),而试验3组的产蛋率显著降低(P<0.05),料蛋比升高(P>0.05);试验组的繁殖性能指标与对照组差异不显著。因此,饲料中添加复合微生态制剂可以提高蛋种鸡产蛋前期的生产性能,本试验中复合微生态制剂的适宜添加量为100 g/t。This study was designed to investigate the effects of supplementation of composite probiotics on production performance of layer breeders.A flocks of 384,15-week-age Hy-line brown parents were randomly divided into four groups,each group was assigned 4 replications and 24 layers per replication.Control group was fed basal diet,test 1,2,3 groups were added 50,100,200 g/t of composite probioticsin in the basal diet.The results showed that the test 3 group of average eggs weight was significantly higher than the control group（P0.05）,but open day age later than the control group.In 27 to 30-week-age,the test 2 group greatly improved the laying ratio and reduced the ratio of feed to eggs（P0.05）,but the test 3 group of the laying ratio was significantly lower（P0.05） and the ratio of feed to eggs was higher（P0.05）.The reproductive performance index had no significant difference in each group.Therefore,feed composite probiotics could improve the chicken egg early production performance,the amount of 100 g/t of composite probiotics was appropriate for the experiment.
