| 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。 |

| Abstract: | 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(P<0.05),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(P<0.05),but the test 3 group of the laying ratio was significantly lower(P<0.05) and the ratio of feed to eggs was higher(P>0.05).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. |
