摘要:
目的 研究饲粮中添加红曲酒糟对蛋鸡生产性能、蛋品质的影响,为红曲酒糟在蛋鸡饲粮中的应用提供参考。 方法 选取38周龄海兰褐蛋鸡192只,随机分为4组,每组6个重复,每个重复8只。对照组饲喂基础饲粮,试验Ⅰ组、试验Ⅱ组、试验Ⅲ组分别用4%、8%、12%红曲酒糟等量替代基础饲粮中的豆粕(去皮豆粕),预试期14 d,正试期42 d。 结果 结果表明:1)红曲酒糟干物质中粗蛋白质含量为46.18%、淀粉含量为10.46%、粗脂肪含量为8.75%、蛋白质消化率为52.47%,同时氨基酸含量丰富(尤其是含硫氨基酸达2.43%)。2)饲粮中添加4%~12%红曲酒糟对蛋鸡生产性能无显著影响(P>0.05),可一定程度上提高蛋鸡采食量(尤其是热应激环境下)(P>0.05)。3)蛋鸡饲粮中添加4%~12%红曲酒糟对蛋型指数、蛋壳强度、蛋壳厚度等指标无显著影响(P>0.05),添加8%~12%红曲酒糟28 d后,可显著提高蛋黄色泽(P<0.05)。 结论 红曲酒糟是一种优质蛋白饲料,在蛋鸡饲粮中替代豆粕使用,对蛋鸡生产性能无显著影响,可提高蛋黄色泽,一定程度上改善蛋品质。 Abstract:Objective This experiment was conducted to study the effects of feeding Hongqu glutinous rice wine grains (HGG) diet on the performance and egg quality of laying hens. Method A total of 192 38-week-old Hy-Line Brown laying hens were randomly divided into 4 groups with 6 replicates per group and 8 laying hens per replicate. The basal diet of experimental groups I-III were replaced (equivalent substitution) the soybean meal (dehulled soybean meal) with 4%, 8%, and 12% HGG, respectively, and the control group was fed basal diet. After 14 days pre-test period, enter the formal feeding experiment period which lasted for 42 days. Result The results showed as follows: 1) There was 46.18% crude protein, 10.46% starch, 8.75% ether extract, 52.47% protein digestibility, and rich in amino acids (especially 2.43% sulfur-containing amino acids) in HGG based on dry matter. 2) The dietary 4%~12% HGG had no significant effect on the production performance of laying hens (P>0.05), while increased the feed intake of the layers to a certain extent (especially under the heat stress environment) (P>0.05). The dietary 4%~12% HGG had no significant effect on the egg shape index, eggshell strength and eggshell thickness (P>0.05), while the egg yolk color was significantly increased after feeding 8%~12% HGG dietary for 28 days (P<0.05). Conclusion It can be concluded that HGG is a kind of high quality protein feed, which could replace soybean meal in the diet of laying hens. It had no significant effect on performance of laying hens, but could improve the yolk color and egg quality to a certain extent. -
