应用线性规划技术作家畜选种选配决策

在五个遗传目标约束下,经对8头乳公牛用电子计算机优化选择实验,得出在不降低乳脂率,乳蛋白率等生产性能条件下,预期后裔产奶量改进达231～278kg。根据选配线性规划数学模型的特殊系数结构,应用“运输问题”的简便求解方法,求得畜群的最佳交配组合,结果使估测的后裔指数提高约9％。

APPLICATION OF LINEAR PROGRAMMING TECHNIQUES IN LIVESTOCK AND MATE SELECTION

The linear programming models were developed for optimum livestock and mate selection. Through a computerized selecting test for 8 dairy sires under 5 genetic goals, the milk production of the progeny, on the average, was expected to be 231-278 kg with no reduction in 8 other production Waits, such as fat and protein percentages.Ac cording to special coefficient construction of linear programming model for mate selection, the simple "transportation problem" method was used to obtain the optimum mating pairs so that the progeny index inceased about 9%.
