摘要
将15头草原红牛平均分成3组,1、2、3组依次饲喂青黄贮玉米秸型日粮、玉米秸饲料块型日粮和玉米酒糟型日粮,进行268d的饲养试验,然后屠宰。1、2、3组试验牛的日增重依次为1022g、1140g和1186g;屠宰率依次是57.44%、58.73%和58.31%;净肉率依次是48.35%、50.06%和49.45%。各种饲料和活牛价格按时价计算,经济效益最好的日粮是玉米酒糟型,其次是玉米秸饲料块型,青黄贮玉米秸型效益较差。
A feeding experiment for268days was conducted with15China Red Cattle,which were divided randomly into three groups,fed three diets incorporated with processed corn stalk which were corn stalk silage(1 st group),corn stalk cake(2 nd group)and distillery refuse plus shredded dry corn stalk(3 rd group),respectively.Then,A subsequent slaughter experiment were carried out when finishing the feeding experiment.The results showed that daily weight gain was1022g,1140g,1186g,dressing percentage was57.44%,58.73%,58.31%,net meat rate was48.35%,50.06%,and49.45%,respectively.Among the above three groups,Economic effect of the3 rd group was highest,the2 nd was higher and the1 st was lowest,calculating according to the current price of all feeds and live weight.
