摘要
根据某养猪场2009年与2014年实际养殖情况,主要分析和解决了关于生猪养殖经营管理的3个问题,即运用不等式解决种猪与肉猪的比例关系问题,进而得到盈亏平衡时,母猪的平均产仔量;运用一、二胎饱和思想,建立数学模型,求得选种率与母猪的存栏量;通过得到的数据,由价格随时间的变化曲线图,得到经营策略,并运用MATLAB软件,求得母猪的存栏数与肉猪的存栏数曲线图。
According to actual breeding of a pig farm in 2009 and 2014,three problems about pig breeding management were analyzed and solved.Inequation was used to calculate the proportion of breeding pigs and pork pigs ,and could get the sow litter size,according to the first and the second off-spring quantity reach saturation ,mathematical modeling was built to calculate the seed selection ratio and sow breeding stock, operating strategy were got based the data and the price time graph, sow breeding stock and pork pig breeding stock graph were obtained by using MATLAB.
