【摘要】：为研究微生态制剂对绿壳蛋鸡生产性能和蛋品质的影响,试验选取180只350日龄健康东乡黑羽绿壳蛋鸡,随机分为3个组,每组6个重复,每个重复10只。其中对照组(A组)饲喂基础日粮,试验组(B、C组)分别在基础日粮中添加0.2%、0.5%微生物制剂。预饲期7 d,正试期21 d。结果显示:1试验第2周,试验组产蛋率较对照组分别提高了13.21%、18.87%(P0.05);第3周,试验组较对照组产蛋率分别提高了15.09%、20.75%(P0.05),平均蛋重分别提高了6.71%、8.33%(P0.05),料蛋比分别降低了8.33%、13.51%(P0.05)。2试验第21天,试验组鸡蛋的蛋黄颜色达到了9.5级,显著高于对照组(P0.05)。微生态制剂对其他常规蛋品质无显著影响(P0.05)。表明,蛋鸡饲粮中添加微生态制剂可显著提高东乡黑羽绿壳蛋鸡生产性能和鸡蛋的蛋黄色泽,对其他常规蛋品质无负面影响。
[Abstract]:In order to study the effect of microecological preparation on the performance and egg quality of green shell laying hens, 180 healthy Dongxiang black feathered green hens aged 350 days were randomly divided into 3 groups, 6 replicates in each group and 10 in each replica. The control group (group A) was fed with basal diet, and the experimental group (group B) was fed with 0.22% microorganism preparation. The prefeeding period was 7 days and the trial period was 21 days. The results showed that in the second week of the experiment, the laying rate of the test group was increased by 13.21% (P 0.05) than that of the control group, and in the third week, the laying rate of the test group was increased by 15.09% (P0.05), the average egg weight was increased by 6.71% and 8.33% (P0.05), and the ratio of feed to egg was decreased by 8.33% (P 0.05) on the 21st day of the experiment, and the average egg weight was increased by 6.71% (P0.05), the average egg weight was increased by 6.71% (P0.05), and the ratio of feed to egg was decreased by 8.33% (P0.05) in the third week. The egg yolk color of the test group reached 9.5 grade, which was significantly higher than that of the control group (P0.05). There was no significant effect of microecological preparation on other conventional egg quality (P0.05). The results showed that the production performance and egg yolk color of Dongxiang black feather green shell laying hens could be significantly improved by adding microecological agents to the diet of laying hens without any negative effect on other conventional egg quality.
