摘　　要：通过建立数学模型来分析生猪养殖场的经营管理,根据市场情况通过决定留种数量、配种时间、存栏规模等优化经营策略以提高盈利水平.收集大量的数据,利用拟合曲线的方法得到三次方程,应用Mathematica8.0求得:问题一:当生猪养殖成本及生猪价格保持不变,且不出售猪苗,小猪全部转为种猪与肉猪,要达到或超过盈亏平衡点,每头母猪每年平均产仔量要达到9头.建立线性方程求得:问题二:该养殖场养殖规模达到饱和时,小猪选为种猪的比例为0.03,母猪的存栏数约为996头.利用蛛网模型的差分方程方法得出:问题三:猪场的最佳经营策略,不仅使自己减少了因价格波动而带来的损失,而且大大消除了市场的不稳定性.through the establishment of mathematical model to analyze the management of pig farms, by determining seed number,breeding time, herds scale optimization strategies to improve the profit level according to the market situation.Collect a lot of data, using the method of curve fitting to obtain three equations, obtained with the help of Mathematica8.0：Question one： when the pig breeding cost and hog prices remain unchanged, and not sell the piglet, pig all turned to pig and pork, to reach or exceed the balance point of profit and loss, the average amount of litter per sow per year to reach the head.The establishment of the linear equation：Question two： the farm scale reaches saturation, the pig pig ratio was selected as the number of herds, about 996 head.That the use of the cobweb model differential equation method：Question three： Pig＇s best business strategy, not only make their own reduced due to price fluctuations caused the loss, but also greatly eliminates the instability of the market.
