【摘要】：为了研究复合菌微生态制剂对产蛋后期蛋鸡生产性能和蛋品质的影响,试验选择62周龄体况良好、产蛋率接近的健康海兰褐蛋鸡10 000只,随机分为2组,每组5个重复,每个重复1 000只。对照组饲喂基础日粮,试验组饲喂基础日粮+0.05%复合菌微生态制剂(500 g/t)。预试期1周,正试期4周。结果表明:复合菌微生态制剂对62周龄蛋鸡采食量无显著影响(P0.05),能提高蛋鸡产蛋率,延缓产蛋后期产蛋率的下降趋势,试验组平均产蛋率较对照组显著提高(P0.05);提高蛋鸡蛋重,降低不合格蛋率,提高蛋壳强度,但差异均不显著(P0.05),对蛋壳厚度和蛋黄颜色无显著影响(P0.05),显著增加蛋白高度和哈氏单位(P0.05)。说明添加0.05%复合菌微生态制剂可以提高蛋鸡生产性能,改善蛋品质。
[Abstract]:In order to study the effect of microecological preparation of compound bacteria on the performance and quality of laying hens in late laying stage, 10 000 healthy Hailan brown laying hens with good body condition and similar laying rate were selected and randomly divided into 2 groups with 5 replicates in each group. 1, 000 per repetition. The control group was fed basic diet, and the experimental group was fed with 0.05% compound microorganism microecological preparation (500g / t). The pretest period was 1 week and the positive test period was 4 weeks. The results showed that the microecological compound bacteria had no significant effect on the feed intake of 62-week-old laying hens (P0.05), but could increase the laying rate and delay the declining trend of laying rate in the later laying period. The average egg laying rate in the experimental group was significantly higher than that in the control group (P0.05), and the egg weight was increased. But the difference was not significant (P0.05), but had no significant effect on egg shell thickness and yolk color (P0.05), and significantly increased protein height and Hardy unit (P0.05). The results showed that adding 0.05% compound microorganism microecological agent could improve the performance and egg quality of laying hens.
