摘要： 为对比玉米秸秆不同方法处理对肉牛日粮营养物质表观消化和生产经济效益的影响。本试验选用杂交肉牛16头，随机分为4个处理组，即干玉米秸秆组、干秸秆青贮组、微生物处理组、氨化处理组。饲养试验和消化代谢试验的结果表明，肉牛饲喂不同处理秸秆日粮的营养物质表观消化率没有明显的差异（p<0.05），有机物表观消化率为53.3%~61.8%，秸秆处理可明显提高可消化有机物的进食量（DOM）和肉牛养殖经济效益，以秸秆氨化处理的经济效益较高。

Abstract: Sixteen crossbred feedlot beef were selected to investigate the nutrient digestible and economical efficiency effects of three differently processed corn stalk and dry corn stalk. The animal randomly divided in to four groups including dry stalks silage, microbial fermented, ammonianized stalks and dry stalks( control group ), The digestible experiment result showed that voluntary intake of digestible organ matter was higher(p<0.05) in animals consuming treatment stalk. The nutrient digestibility of total tract were no significant (p>0.05) difference among the processed corn stalk and dry corn stalk. The growth trials beefs fed treated corn stalk diets gained faster and tended to be more efficient than those fed the dry corn stalk diets. However, the fattening result of ammonianized stalks improved beef performance and had a good economic return.
