| 摘 要： | 在蛋鸡日粮中添加不同水平的复合益生素,研究其对蛋鸡生产性能及肠道微生物菌群的影响。将900只海兰褐蛋鸡随机分成对照组、试验1组和试验2组3个处理,每个处理3个重复,在日粮中分别添加0,3%,5%的复合益生素。试验结果表明,试验1组和试验2组比对照组平均蛋质量分别提高0.53,0.91 g,且差异显著(P<0.05);产蛋率分别提高1.72%和1.89%,差异显著(P<0.05);破(软)蛋率分别降低13.79%和17.24%;料蛋比分别降低0.03和0.05;乳酸菌浓度分别提高了6.26%和6.52%;大肠杆菌浓度分别降低了4.79%和6.18%,但差异不显著(P>0.05)。

| Abstract: | This experiment was conducted to evaluate the effects of combined probiotics supplementation on production performance and intestinal flora of laying hens.Nine hundred Hailan brown laying hens were random assigned to 3 dietary treatments with 3 replicates.These laying hens received the same basal diet supplemented with 0,3%,5% combined probiotics-supplementation,respectively.Results showed as follows: the treatments with 3% and 5% combined probiotics-supplementation significantly increased average egg weight by 0.53,0.91g(P<0.05),while significantly increased laying rate by 1.72% and 1.89%(P<0.05),respectively;the treatments with 3% and 5% combined probiotics-supplementation decreased the percentages of broken and soft-shell eggs by 13.79% and 17.24%,decreased feed-egg ration by 0.03 and 0.05,increased lactic acid bacteria counts by 6.26% and 6.52%,and decreased colon bacillus counts by 4.79% and 6.18%,respectively.In conclusion,these data indicated that combined probiotics-supplementation could enhance production performance and improve intestinal flora of laying hens. |
