摘要
以概略养分分析法测定了花生壳、麦秸和花生壳—麦秸型日粮中粗蛋白质、粗纤维、钙和磷的含量;以5 头育肥公牛进行日粮消化率测定试验;并用16 头成年秦川公牛和夏洛来×南阳牛F1 公牛,以花生壳—麦秸型日粮育肥饲养60 d- 结果表明花生壳和麦秸中CP含量低,Ca,P不平衡;以花生壳、麦秸为主要粗饲料配合棉饼等原料所组成的日粮,能够满足肉牛对于CP,Ca 和P的需要,DM,CP和CF的消化率分别为44-60 % ,61-88 % 和30-41% - 以此日粮育肥秦川牛和夏杂牛,平均日增重分别为1-244 kg 和1-605 kg。
For the purpose of evaluating the typical ration based on peanut shell and wheat straw,analysrs was conducted on the nutrients of the roughages and ration,determination was conducted on the digestion coefficient of ration with 5 male beef cattle for 7 days,a feeding trial was carried out using 16 adult bull with the typical ration.The results showed that the ration mainly composed of peanut shell,wheat straw and cotton seed cake could provide sufficient nutrition for beef cattle because of high protein level and reasonable Ca,P proportion;the digestion rate of DM,CP and CF were 44.60%,61.88% and 30.41% respectively.With this ration for beef cattle fattening,the daily gain of Qinchuan bull and Charolais×Nanyang F 1 bull could reach 1.244 kg and 1.605 kg respectively in the two month fattening period,which irndicates that this ration can be used as the typical ration for beef catthe in the countryside.
