试验旨在探究菌酶复合物对饲喂小麦型饲粮蛋鸡生产性能、蛋品质、蛋成分和养分表观代谢率的影响。试验选用360只京红蛋鸡，随机分为3组，每组10个重复，每个重复12只蛋鸡。对照组饲喂玉米-豆粕型饲粮，小麦组利用10％小麦替换对照组饲粮中同等比例玉米，菌酶复合物组在小麦组饲粮的基础上添加0。02％的菌酶复合物。预试期3d，正式试验期28d。结果显示，对照组、小麦组和菌酶复合物组蛋鸡的生产性能、蛋品质和蛋成分无显著差异(P＞0。05)。随着试验时间增加，小麦组的蛋黄叶黄素含量逐渐降低。第22、25、28 d，小麦组的蛋黄叶黄素含量显著低于对照组(P＜0。05)，菌酶复合物组的蛋黄叶黄素含量显著高于小麦组(P＜0。05)。小麦组蛋鸡的干物质、粗蛋白、钙和磷的表观代谢率低于对照组(P＞0。05)，而菌酶复合物组蛋鸡对粗蛋白和磷的表观代谢率显著高于对照组和小麦组(P＜0。05)。研究表明，使用10％小麦替代玉米不会影响蛋品质和蛋成分，但会降低蛋黄颜色和叶黄素含量，菌酶复合物能够增加小麦组的蛋黄叶黄素含量，改善蛋黄颜色，提高蛋鸡养分表观代谢率。
Effects of bacterial-enzyme complex on production performance,egg quality,egg composition,and nutrient apparent metabolic rate in laying hens fed with wheat diet
The experiment was to investigate the effects of bacterial-enzyme complex on the production performance,egg quality,egg composition,and nutrient apparent metabolic rate in wheat-based laying hens.A total of 360 Jinghong laying hens were randomly divided into three groups with 10 replicates in each group and 12 laying hens in each replicate.The control group was fed with corn-soybean meal diet.The wheat group used 10％wheat to replace the same proportion of corn in the control group diet.The bacterial-enzyme complex group was supplemented with 0.02％bacterial-enzyme complex on the basis of wheat group diet.The pre-test period was three days,and the formal test period was 28 days.The results showed that there was no significant difference in production performance,egg quality,and egg composition among the control group,wheat group,and bacterial-enzyme complex group(P＞0.05).The lutein content of egg yolk in wheat group decreased gradually with the increase of experiment time.On the 22nd,25th,and 28th day,the lutein content of egg yolk in wheat group was significantly lower than that in control group(P＜0.05),and the lutein content of egg yolk in bacterial-enzyme complex group was significantly higher than that in wheat group(P＜0.05).The apparent metabolic rates of dry matter,crude protein,calcium,and phosphorus in wheat group were lower than those in control group(P＞0.05),while the apparent metabolic rates of crude protein and phosphorus in bacterial-enzyme complex group laying hens were significantly higher than those in the control group and wheat group(P＜0.05).The study indicates that using 10％wheat instead of corn can not affect egg quality and egg composition,but can reduce yolk color and lutein content.Bacterial-enzyme complex can increase yolk lutein content of wheat group,improve yolk color and improve nutrient apparent metabolic rate of laying hens.
