摘　　要：试验旨在研究红曲米对产蛋后期仙居鸡生产性能、蛋品质及血清脂类生化指标的影响。试验选取52周龄仙居蛋鸡270只,随机分为3组,每组3个重复,每个重复30只鸡。对照组饲喂玉米-豆粕型基础日粮,试验组分别在饲粮中添加6%、12%红曲米替代玉米和麦麸(6%红曲组、12%红曲组)。结果显示:与对照组相比,6%和12%红曲组料蛋比显著降低(P<0.05);6%和12%红曲组全蛋胆固醇含量显著降低(P<0.05);饲喂含6%、12%红曲米的日粮6周后,血清总胆固醇含量显著降低(P<0.05),高密度脂蛋白(HDL-C)显著提高(P<0.01)。综上所述,饲粮中添加6%~12%红曲米能够显著降低产蛋后期仙居鸡料蛋比,降低血清和全蛋中总胆固醇含量,提高高密度脂蛋白,在提高产蛋性能、生产低胆固醇鸡蛋中具有良好的应用价值。This experiment was conducted to investigate the effects of red yeast rice on production performance,egg quality and serum lipid biochemical indexes of Xianju chicken at the late laying period.Two hundred and forty 52-week-age Xianju chicken were randomly divided into 3 groups with 3 replicates per group and 30 hens in each replicate.Hens in the control group were fed a basal diet,corn and wheat bran in diets were substituted with 6%and 12%red yeast rice in the experiment groups,respectively(6%red yeast group and 12%red yeast group).The results showed as follows:compared with the control group,feed to eggs ratio in the 6%and 12%red yeast rice groups were significantly decreased(P<0.05),the cholesterol content of whole eggs in 6%and 12%red yeast group significantly decreased(P<0.05),respectively.After feeding Xianju chicken at the late laying period with diets contained 6%and 12%red yeast rice,the total cholesterol(TC)content in serum was significantly decreased(P<0.05),while the high density lipoprotein(HDL-C)was significantly increased(P<0.01).In conclusion,diet with 6%to 12%red yeast rice could decrease the feed to egg ratio and the TC content in both serum and egg,and increase the HDL-C in serum,which suggested to be a good application in improving egg production performance and producing low cholesterol eggs.
