摘 要
奶牛营养代谢病是现代集约化养殖中常见的疾病类型，其发病与饲料配方不合理、饲养管理不当及机体代谢紊乱密切相关。本研究旨在深入探讨奶牛营养代谢病的发病机理，并提出科学有效的防控策略。通过整合国内外相关文献资料，结合实验室检测数据和田间试验结果，系统分析了酮病、低血钙症、酸中毒等典型代谢病的发生机制及其对奶牛生产性能和健康的影响。研究表明，能量负平衡、矿物质失衡以及瘤胃微生态失调是导致这些疾病的关键因素。在此基础上，本研究创新性地提出了基于精准营养调控的综合防控方案，包括优化日粮结构、动态调整饲喂策略以及应用功能性添加剂等措施。试验结果表明，实施该防控方案后，奶牛代谢病的发病率显著降低，产奶量和乳品质得到有效提升。此外，本研究还开发了一套适用于规模化牧场的营养代谢监测体系，能够实时评估奶牛健康状况并预警潜在风险，为牧场精细化管理提供了重要技术支持。

Abstract
Dairy cow nutritional me tabolic diseases are common ailments in modern intensive farming, closely associated with irrational feed formulations, improper feeding management, and me tabolic disorders within the animal. This study aims to explore the pathogenesis of these me tabolic diseases in dairy cows and propose scientifically effective prevention and control strategies. By integrating domestic and international literature, along with laboratory test data and field trial results, a systematic analysis was conducted on the mechanisms of typical me tabolic diseases such as ketosis, hypocalcemia, and acidosis, as well as their impacts on the production performance and health of dairy cows. The research reveals that negative energy balance, mineral imbalance, and rumen microbiota dysbiosis are critical factors contributing to these diseases. Based on these findings, an innovative comprehensive prevention and control scheme grounded in precision nutrition regulation was proposed, encompassing measures such as optimizing dietary structure, dynamically adjusting feeding strategies, and utilizing functional additives. Experimental results indicate that the implementation of this scheme significantly reduced the incidence of me tabolic diseases in dairy cows while effectively enhancing milk yield and milk quality. Furthermore, this study developed a nutritional me tabolic monitoring system tailored for large-scale farms, capable of real-time assessment of dairy cow health and early warning of potential risks, providing crucial technical support for refined farm management.
