β-羟基-β甲基丁酸系物质在制备缓解断奶仔猪免疫应激及促肌肉生长饲料中的应用
摘要：
本发明公开了一种β-羟基-β甲基丁酸系物质在制备缓解断奶仔猪免疫应激及促肌肉生长饲料中的应用。缓解断奶仔猪免疫应激及促肌肉生长饲料包括β-羟基-β甲基丁酸系物质和基础日粮，β-羟基-β甲基丁酸系物质占基础日粮质量总量的0.6％-1.2％。本发明的β-羟基-β甲基丁酸系物质可以降低断奶仔猪平均日增重和平均日采食量，提高料重比，提高了平均日增重和平均日采食量，降低了料重比，缓解了注射脂多糖导致的仔猪生产性能的下降和瘦肉率的降低。
摘要（英）：

The invention discloses application of a beta-hydroxyl-beta methyl butyrate substance to preparation of feed for alleviating immunological stress of weaned piglets and promoting growth of muscles. Thefeed for alleviating the immunological stress of the weaned piglets and promoting the growth of the muscles is prepared from the beta-hydroxyl-beta methyl butyrate substances and basic diet, whereinthe beta-hydroxyl-beta methyl butyrate substance is 0.6 to 1.2 percent of the total mass weight of the basic diet. The beta-hydroxyl-beta methyl butyrate substance disclosed by the invention has the advantages that the average daily gain and the average daily intake of the weaned piglets can be reduced, a feed-gain ratio is reduced, and lowering of the production performance of the piglets and reduction of lean meat percentage caused by injection of lipopolysaccharide can be alleviated.
