摘要
为探究青贮饲用高粱对肉牛生长性能及血液指标的影响,综合考虑各种青贮饲用高粱的营养搭配是否满足肉牛营养需要,以期推动中国现代肉牛经济发展。以安格斯3代阉牛为试验牛,以BJ0603青贮饲料作为基础饲粮,每个日粮处理组挑选3头牛进行屠宰分割,测定生长性能及血液指标。结果表明:青贮饲用高粱饲喂育肥肉牛,通过对肉牛血液指标的检测,发现对其肝脏功能、脂类的代谢及电解质水平等均没有不利影响。50%青贮高粱和50%青贮玉米混合青贮饲喂效果较好,不仅能增加肉牛机体对能量的利用率且对肉牛肾脏功能无不利影响。
In order to explore the effects of silage sorghum on beef cattle growth performance,digestion and blood index,the nutritional combination of various silage sorghum was considered comprehensively to meet the nutritional needs of beef cattle,in order to promote the development of modern beef cattle economy in China.In this study,three simmental steers were used as experimental cattle,and BJ0603 silage was used as basic diet.Three cattle were selected from each diet treatment group for slaughtering and segmenting.Growth performance,digestion and blood indexes were measured.The results showed that silage sorghum had no significant effect on liver function,lipid metabolism and electrolyte level of fattening beef cattle.Mixed silage of 50%silage sorghum and 50%silage maize could significantly increase the content of urea nitrogen in blood.It could not only increase the energy utilization rate of beef cattle,but also had no adverse effect on the kidney function of beef cattle.
