We examined the replacement of soy isolated protein by a solid fraction coming from brewery liquid waste, in the preparation of soy protein and brewer's yeast mixtures (50:50) to feed growing chickens. The replacement of 20 percent soy protein by brewery waste protein to the diet, showed no significant differences in the growth and food intake of the chickens, when compared with soy protein fed chickens. Protein Efficiency Ratio (PER) and Net Protein Ratio (NPR) values of the diets were also very similar and the concentration of plasma and liver lipids remained approximately the same. Higher levels of brewery waste reduced the performance of chickens although total lipids, cholesterol and triacylglycerols in plasma, as well as total lipids and cholesterol in liver were not affected. The data reported here indicated that brewery waste can be used as a complementary protein source in broiler chicken diets.
我们研究了在制备大豆蛋白和啤酒酵母混合物（50:50）以喂养生长中的鸡时，用来自啤酒厂废液的固体成分替代大豆分离蛋白的情况。与喂食大豆蛋白的鸡相比，用啤酒厂废蛋白替代日粮中20%的大豆蛋白，鸡的生长和采食量没有显著差异。日粮的蛋白质效率比（PER）和净蛋白比（NPR）值也非常相似，血浆和肝脏脂质浓度基本保持不变。更高水平的啤酒厂废料会降低鸡的生长性能，尽管血浆中的总脂质、胆固醇和三酰甘油以及肝脏中的总脂质和胆固醇不受影响。此处报告的数据表明，啤酒厂废料可作为肉鸡日粮中的补充蛋白质来源。
