摘要
研究复合微生态制剂对蛋鸡生产性能及鸡蛋品质的影响。结果表明:0.10%复合微生态制剂组蛋鸡平均产蛋率提高了4.79%(P<0.05),料蛋比降低了4.72%(P<0.05);鸡蛋的蛋壳厚度、蛋壳强度和哈氏单位,以0.10%复合微生态制剂组为最好,较对照组分别提高了4.88%、3.53%和3.32%,且差异均显著(P<0.05);但其他试验组较对照组间差异均不显著(P>0.05)。复合微生态制剂添加量以0.10%水平为佳。
The effect of compound microecological preparation on production performance of layers and egg quality was stud- ied. The results showed that： the average egg production of adding 0.10% compound microecological preparation group were increased by 4.79% （P〈0.05）, feed conversion ratio decreased by 4. 72% （P〈0.05） ; the egg shell thickness, shell strength and Haugh unit of adding 0.10% compound microecological preparation group were the best, compared to the control group, were increased by 4.88%, 3. 53% and 3.32% ,respectively, and the differences were significant （P〈0.05）; but the differ- ences of the other test groups with the control group were not significant （P〉0.05）. Adding 0.10% compound microecologi- cal preparation was good.
