英文文献摘要：
This study compares and contrasts the profitability of different dairy management practices through precision livestock farming. Feed analysis and crop yields were simulated. The proposed alternative feeding program demonstrated less manure and nutrient excretions. When mathematical programming model was employed, uniform rate application manifested the highest selected economic values.

本研究比较和对比了通过精细化畜牧业不同的乳品管理实践的盈利能力。模拟饲料分析和作物产量。提出的替代喂养方案表明粪便和营养物质的排泄较少。当采用数学规划模型时，均匀率应用表现出最高的选择经济价值。
