摘要
圈养条件下,将16头供试牛随机分成两组,每组8头,试验期为30天。在试验期内,其结果为:试验组牛日增重较对照组提高,差异极显著(p<0.01)。从经济效益分析,试验组牛头日增重2.067Kg,对照组头日增重1.558Kg,纯收入试验组高出对照组3.692元/头·天。试验表明,按规定量加入“糖萜素”于精料中,可使牛增重加快,提高饲料利用率,降低增重成本,从而提高经济效益。
Under the condition of enclose, 16 cow divided into two groups stochastically, each of group is 8 heads, the experimental time is 30 days. In this time of experiment, the result is: perday increase in the test group is improved than antigroup, the discrepancy is significantly(p〈0.01 ). Analyse from economic-benefic, the test group's per-day increase is 2.067Kg, and the anti-group is 1.558Kg, the corresponding net income is 3.692 yuan higher .The test indicated that, add Sacchaficterpenin in feed ,can improve the weight of cow, increase the feed utilize efficiency, reduce cost of weighting, increase economic-benefic accordingly.
