摘要
本文建立了包括肥猪价格、饲料价格、饲料能量水平、肥育期日增重、料肉比以及其它支出在内的生长肥育猪适宰体重估计模型。并对估计模型进行校正分析和实用性简化。
Dealing with the price of pig (a) and feed (b), energy level (E,MJ),daily gain (G), feed/gain (R) and other investment (d), a profit functionmodel on the optimum slaughtering weight (W), is established as W=[x+(a-bR)G-d/0.544E]~3 based on biological and mathematical principles. xin the profit function model equals W_1^(1.75)-W_0^(1.75)/1.75(W_1-W_0), where W_1 andW_0 stand for the finishing and beginning weights, respectively. Finally, asimplified model is figured out for practical usage.
