【摘要】：本试验从饲养成本降低方面开展研究,提出一种节本增效的肉牛育肥模式,供育肥场参考。另一方面依据育肥牛饲养成本,综合评价架子牛购买价格,设计育肥牛的经营决策系统,指导架子牛购进决策。本文的研究工作主要包括：1.开展了肉牛持续育肥与低精料日粮育肥方案饲喂效果的观测。通过饲养试验对两种育肥模式中不同阶段日增重的变化和养殖成本进行了统计和分析,结果表明：低精料育肥方案在整个育肥期的日增重情况呈上升趋势,持续育肥方案随着时间的推移呈下降趋势。短期育肥选用持续育肥方案利润较大；而低精料育肥方案的绝对增重较大,适合长期育肥。2.设计育肥牛经营决策系统。根据饲养试验所得育肥期综合成本,设计投入资金与产出效益计算公式,应用EXCEL应用系统,编辑育肥牛经营决策系统。通过实时采集育肥牛饲养成本和销售收入数据,预测不同地区不同阶段的养殖效益,供养殖户和牧场对未来的经营活动作出科学的判断,进而降低养殖风险,提高养殖效益。3.模拟运行育肥牛经营决策系统。
[Abstract]:In this experiment, the study was carried out from the aspect of reducing the feeding cost, and a new fattening model for beef cattle was put forward, which could be used as reference for fattening farm. On the other hand, according to the raising cost of fattening cattle, the purchase price of shelf cattle is evaluated synthetically, the management decision system of fattening cattle is designed, and the purchase decision of shelf cattle is guided. The research work of this paper mainly includes: 1. The effects of continuous fattening and low concentrate diet fattening on beef cattle were observed. The changes of daily gain and breeding cost in different stages of two kinds of fattening models were analyzed through feeding experiments. The results showed that the daily gain of low concentrate fattening schemes was on the rise during the whole fattening period. The continuous fattening program showed a downward trend with the passage of time. For short term fattening, continuous fattening scheme is more profitable, while low concentrate fattening scheme has higher absolute weight gain, which is suitable for long term fattening. 2. Design the management decision system of fattening cattle. According to the comprehensive cost of fattening period, the formula of investment and output benefit was designed, and the excel application system was used to edit the management decision system of fattening cattle. By collecting the data of raising cost and sales income of fattening cattle in real time, the benefit of breeding in different areas and different stages can be predicted, so that farmers and pastures can make scientific judgment on the future management activities, and then reduce the risk of breeding and increase the benefit of breeding. Simulation operation of fattening cattle management decision system.
