里氏木霉对酒糟饲料的营养价值影响评价

Effects of Trichoderma reesei Additive on the Nutritional Value of Feed Produced by Distillers Grains

为充分利用酒糟资源,通过固态发酵将其制成营养价值较高的发酵饲料。从粗蛋白、粗脂肪、灰分、总糖、粗纤维、氨基酸组成等方面考察了不同添加量里氏木霉(3%、5%、8%)对酒糟固态发酵前后营养价值的影响。结果表明,添加5%的里氏木霉进行固态发酵后,酒糟饲料营养价值较高。

Distillers grains is the by-product in liquor-making and could be used to produce feed through solid-state fermentation. In this study, the effects of adding different levels of Trichoderma reesei on the nutritional value of feed produced by distillers grains were investigated by comparing crude protein, crude fat, total sugar, crude fiber, and amino acid compositions before and after fermen- tation. The results suggested that, the addition of 5 % Trichoderma reesei could achieve the highest nutritional value after solid-state fermentation.
