摘 要
随着全球畜牧业的快速发展，肉羊舍饲养殖模式因其高效、可控的特点逐渐成为主流。然而，饲料配方的科学性直接影响养殖效益和羊肉品质。本研究旨在优化舍饲肉羊饲料配方，以提高生产效率并降低环境负担。通过收集国内外相关数据，结合本地资源特点，采用线性规划模型与营养平衡分析方法，构建了适用于不同生长阶段肉羊的饲料配方体系。结果表明，优化后的配方显著提高了日增重（平均提升15%），同时降低了饲料转化比（约减少8%）。此外，该配方有效减少了氮磷排放，展现了良好的生态效益。本研究创新性地将地方特色饲料资源纳入配方设计，并通过多目标优化实现了经济效益与环境可持续性的平衡，为舍饲肉羊产业的健康发展提供了重要参考。

OPTIMIZATION OF FEED FORMULATION FOR MEAT SHEEP UNDER CONFINED FEEDING SYSTEMS
ABSTRACT
With the rapid development of global animal husbandry, the indoor feeding model for meat sheep has gradually become mainstream due to its high efficiency and controllability. However, the scientific nature of feed formulations directly affects breeding efficiency and mutton quality. This study aims to optimize feed formulations for indoor-raised meat sheep to enhance production efficiency while reducing environmental burdens. By collecting relevant data from domestic and international sources and integrating local resource characteristics, a feed formulation system suitable for different growth stages of meat sheep was constructed using linear programming models and nutritional balance analysis methods. The results indicate that the optimized formulation significantly increased daily weight gain (an average improvement of 15%) and simultaneously reduced the feed conversion ratio (approximately an 8% decrease). Moreover, this formulation effectively decreased nitrogen and phosphorus emissions, demonstrating favorable ecological benefits. This study innovatively incorporates regional feed resources into the formulation design and achieves a balance between economic benefits and environmental sustainability through multi-ob jective optimization, providing significant reference for the healthy development of the indoor feeding industry for meat sheep.
