【摘要】：为了研究酵素菌发酵蛋白饲料对蛋鸡生产性能、蛋营养成分的影响,试验选择健康、产蛋正常、体重相近的海兰褐蛋鸡576只,随机分为对照组和试验组,每组6个重复,每个重复48只鸡。对照组饲喂玉米-豆粕型产蛋鸡饲料,试验组饲喂玉米-酵素菌发酵蛋白饲料,自由饮水。结果表明:酵素菌发酵蛋白饲料有提高蛋鸡产蛋性能的趋势,但效果不显著(P0.05);酵素菌发酵蛋白饲料可显著提高鸡蛋蛋白质含量(P0.05),降低蛋黄胆固醇含量(P0.05),对蛋脂肪含量及蛋黄中饱和脂肪酸、单一不饱和脂肪酸、多不饱和脂肪酸含量均无显著影响(P0.05)。说明酵素菌发酵蛋白饲料有提高蛋鸡产蛋性能和改善鸡蛋营养品质的作用。
[Abstract]:In order to study the effect of fermenting protein feed by enzyme bacteria on the performance and nutritional composition of egg, 576 Hailan brown laying hens with healthy, normal egg laying and similar body weight were selected and randomly divided into control group and experimental group with 6 replicates in each group. Each repeats 48 chickens. The control group was fed with corn-soybean meal-type laying hens and the experimental group was fed with corn-yeast fermented protein feed and free drinking water. The results showed that the fermenting protein feed of enzyme bacteria had the tendency to improve the laying performance of laying hens, but the effect was not significant (P0.05). The content of egg protein and cholesterol of egg yolk were significantly increased (P0.05) and the content of egg fat and saturated fatty acid in egg yolk were decreased (P0.05). The content of polyunsaturated fatty acids was not significantly affected (P0.05). The results showed that the fermented protein feed by enzyme bacteria could improve laying performance and nutritional quality of laying hens.
