ABSTRACT The objective of this study was to determine the effects of brewer’s yeast hydrolysate (BYH, Saccharomyces cerevisiae) on laying hens. A total of 288 Hy-line Brown laying hens were randomly assigned to 1 of 6 treatments with 8 replications (6 birds per replication). The treatment diets were supplemented with BYH at levels of 0, 0.05, 0.10, 0.50, 1.0 or 3.0%, respectively. The supplementation of BYH diets led to a significant linear (P < 0.05) effect on egg production, egg weight and egg mass during 37–41 and 42–46 weeks. The supplementation of BYH diets also led to a significant linear increase observed in internal egg quality: albumen height (37–41 and 42–46 weeks), Haugh unit (42– 46 weeks), and yolk colour (37–41 and 42–46 weeks), and a significantly linear increase in eggshell thickness (P < 0.05) during 37–41 and 42– 46 weeks. A linear increase was observed on dry matter and nitrogen at 46 weeks of laying hens, and linear increase and linear decrease were detected for Lactobacillus and E. coli at 46 weeks of laying hens, respectively. As a result, dietary BYH had beneficial effects on egglaying performance, egg quality, nutrient digestibility, and excreta microflora in laying hens.

用含有啤酒酵母水解物的日粮喂养的蛋鸡的产蛋量、蛋质量、营养消化率和排泄物微生物群落
摘要 本研究的目的是确定啤酒酵母水解物(BYH,酿酒酵母)对蛋鸡的影响。总共 288 只 Hy-line Brown 蛋鸡被随机分配到 6 个处理中的 1 个,重复 8 次(每次重复 6 只鸡)。处理饮食分别添加了 0、0.05、0.10、0.50、1.0 或 3.0% 的 BYH。在 37-41 周和 42-46 周期间,BYH 日粮的补充对产蛋量、蛋重和蛋重产生显着的线性影响(P < 0.05)。补充 BYH 日粮还导致观察到的内部鸡蛋质量显着线性增加:蛋白高度(37-41 和 42-46 周)、哈夫单位(42-46 周)和蛋黄颜色(37-41 和 42- 46 周),并且在 37-41 周和 42-46 周期间蛋壳厚度显着线性增加(P < 0.05)。蛋鸡46周时干物质和氮呈线性增加,蛋鸡46周时乳杆菌和大肠杆菌分别呈线性增加和线性减少。因此,日粮 BYH 对蛋鸡的产蛋性能、鸡蛋质量、养分消化率和排泄物微生物群有有益影响。
