摘要
采用计算机模拟技术,筛选了以"单位增重饲料费用最低"与"单位增重精料消耗最少"为优化目标的肉牛优化饲料配方;提出了我国农区以氨化秸秆为粗饲料的肉牛"两阶段优化饲养体系";并将在本研究优化饲养体系下的生长育肥期肉牛饲养效益指标,与我国农区传统饲养结果进行了比较,证明该体系较传统饲养具有明显的经济效益与社会效益。
The maximum benefit formulae of beef cattle were chosen by a computer simulation method.The maximum benefits were defined as the minimum concentrate consumption per unit gain or the minimum feed cost per unit gain. Based upon the simulated results,an optimum feeding system,a two-duration maximum feeding system,was developed for beef cattle feeding in China.The comparison results of cattle benefits between the two-duration maximum sys- tern and the rural traditional feeding were also presented,indicating that the two-duration maximum system resulted in a significant benefit social and econo- mic of beef cattle feeding over the traditional feeding.
