5种饼粕类非常规饲料营养价值及其牦牛体外瘤胃发酵特性研究
Study on Nutritional Value of Five Types of Unconventional Feed Cake Meals and Their in Vitro Rumen Fermentation Characteristics in Yaks
摘要
Abstract
This experiment was conducted to com-prehensively evaluate the nutritional and feeding value of five unconventional cake and meal feed ingredients(rapeseed cake,corn germ meal,cottonseed meal,peanut cake and apple pomace)by conventional nutrient composition analysis,protein fraction evalua-tion based on the Cornell Net Carbohydrate and Protein System(CNCPS)and in vitro fermentation technol-ogy,so as to provide theoretical basis for their application in yak raising.The results showed that there were significant differences in conventional nutrient contents among the five cake and meal raw materials(P<0.05).Peanut cake had the highest crude protein(CP)content(50.46%),while rapeseed cake had the high-est ether extract(EE)content(16.39%).Cottonseed meal possessed the highest true protein(TP)content(42.62%),and the non-protein nitrogen(NPN)content of peanut cake was significantly higher than that of other cake and meal materials(P<0.05).In conclusion,peanut cake and cottonseed meal had superior CP and TP contents with high comprehensive nutritional value,while apple pomace presented higher gas pro-duction and energy value.关键词
