摘　　要：为探索以辽宁省养殖户现有条件为基础,以黄贮玉米秸秆为主的低营养水平,长周期的饲养模式生产中高等级牛肉的可行性及配套技术,开展了西门塔尔公牛与辽育白牛母牛杂交后代牛的育肥和屠宰试验。结果表明,采用低营养水平饲养西门塔尔公牛与辽育白牛母牛杂交后代公犊牛(阉割),可能造成生长性能下降,育肥期延长,产肉性能下降等负面结果。但对肉品质无明显影响,采用低营养水平、长周期的饲养模式,同样可生产中高等级牛肉。To exploit feasibility and supporting technology of using existing conditions of farmers in our province, producting high-grade beef by mode of low nutrition and long period, a fattening and slaughtering test of hybrid offspring of Simmental bull and Liaoyu white cow were executed. The results shown that the hybrid offspring be bred by mode of low nutrition, may cause decrease of growth performance, elongation of fattening period, decrease of meat production. But the mode of low nutrition doesn＇t influence to meat quality significantly, thus producting high-grade beef by mode of low nutrition and long period is feasible.
