一种富含红曲色素微生物发酵饲料在蛋鸡养殖中的应用

Application of microbial fermentation feed rich in Monascus pigment for laying hens

选取健康32周龄海兰褐蛋鸡288只,随机分成3组,试验组分别添加0.5%和1.0%的富含红曲色素微生物发酵饲料,考察其对蛋鸡生产性能及蛋品质的影响。结果表明:添加0.5%富含红曲色素的微生物发酵饲料试验组与对照组相比,产蛋率提高了5.82%,破蛋率和料蛋比分别降低了12.36%和3.57%;而在蛋品质上,与对照组相比,平均蛋重和平均蛋黄质量分别提高了3.57%和1.38%,蛋黄中的胆固醇含量降低了5.17%;同时能显著加深蛋黄的红色度和黄色度。

288 healthy 32-week-old Hyline laying hens were randomly allocatted into three groups. Except for the control group, two other groups were fed 0.5% and 1.0% microbial fermentation feed rich in Monascus pigments, respectively. The production performance and egg quality were tested. Results showed that： compared with the control group, the laying rate of experimental group with addition of 0.5% Monascus pigments significantly increased by 5.82%, and broken egg rate and feed to egg ratio decreased by 12.36 % and 3.57%, respectively; average egg weight and average egg yolk weight were increased by 3.57% and 1.38%, respectively;the cholesterol in eggs yolk was decreased by 5.17 %;the red degree and yellow degree of egg yolk were significantly enhanced.
