| 摘 要： | 试验旨在研究日粮中添加合生元对蛋鸡生产性能、蛋品质及经济效益的影响。选用1080只265日龄的正大褐蛋鸡,随机分为6个处理组,每个处理组6个重复,每个重复30只。试验1组为对照组,饲喂玉米—豆粕型基础日粮,试验2~6组在基础日粮中分别添加0.05%、0.1%、0.2%、0.5%和1%合生元,试验期为60 d。结果表明,与对照组相比,试验3、4和5组料蛋比分别降低了6.96(P<0.05)、7.33%(P<0.05)和8.06%(P<0.05),产蛋率分别提高4.05%(P<0.05)、3.54%(P<0.05)和6.17%(P<0.05);试验5组的蛋壳厚度、蛋壳色泽、蛋壳强度和哈氏单位分别提高了5.85%(P<0.05)、6.50%(P<0.05)、15.49%(P<0.05)和2.52%(P<0.05)。因此,0.5%合生元在改善蛋鸡生产性能和蛋品质方面具有显著的效果。

| Abstract: | The objective of this study was to investigate the effects of synbiotics on production performance, egg quality and economic benefits in laying hens. One thousand and eighty Zhengdahe laying hens at 265 days of age were selected, and divided into six groups, and six replicates per group and 30 hens per group. The test 1 group was the control group, was fed a corn-soybean meal diet, and the test 2 to 6 groups were fed with the basal diet supplemented with 0.05%, 0.1%, 0.2%, 0.5%, and 1% of synbiotics. The experiment lasted for 60 days. The results showed that the test 3 to 5 groups of ratio of feed to egg were lower 6.96 (P<0.05), 7.33% (P<0.05) and 8.06% (P<0.05) compared with the control group, respectively, egg production rate were higher 4.05% (P<0.05), 3.54% (P<0.05) and 6.17% (P<0.05). The test 5 group of shell thickness, eggshell color, eggshell strength and Haugh unit were higher 5.85% (P<0.05),6.50% (P<0.05),15.49% (P<0.05) and 2.52% (P<0.05).Therefore, the supplementation of 0.5% synbiotics could improve production performance and egg quality for laying hens, and had significant effect. |
