阿魏酸酯酶的制备及在肉鸡饲料中的应用
Preparation of feruloyl esterase and application in feed of broiler
摘要
Abstract
To reduce non-starch polysaccharides anti-nutritional factor in feed and promote intake of nutrient,the solid-state fermentation technology of feruloyl esterase (FAE) and the influence on nutrient utilization rate were studied. Under optimized conditions of 2∶8 of the ratio for wheat bran and brewers’ spent grain (BSG),2∶4 of the ratio for peptone and yeast,40%of water content,10%of inoculum,6 days of incubation and 33 ℃ of incubation temperature,the activity of FAE was improved to five times compared to unoptimized conditions and the maximum activity was 29.49 U/g. The combination of FAE and Yiduoli enzyme was mixed in feed for broiler. FAE and Yiduoli enzyme could improve the utilization of dry matter,crude protein,crude ash,acidic detergent fiber,but the improvement was limited. The utilization of neutral detergent fiber increased markedly (P<0.01).关键词
