Efficiency Optimization Strategies in Modern Dairy Farms, columnId=1319995134121455784, journalTitle=China Dairy, columnName=DAIRY CATTLE REPRODUCTIVE HEALTH MANAGEMENT, runingTitle=null, highlight=null, articleAbstract=A large-scale dairy farm in China suffered an annual profit loss of up to 8 million RMB due to neglect of key reproductive indicators.This case highlights that reproductive efficiency has become a decisive factor affecting the economic benefits and sustainable development of dairy farms under intensive farming systems.This study focused on reproductive data from large-scale farms,systematically analyzing the calculation methods,influencing factors,and improvement strategies for key indicators such as 21-day pregnancy rate,breeding rate,conception rate,and 150-day non-pregnancy rate.Using real production data, practical application approaches are illustrated,and comprehensive improvement plans are proposed,including calibration of management software parameters,enhancing timeliness of estrus detection and pregnancy diagnosis,and optimizing synchronization protocols.The results showed that through in-depth interpretation and precise application of reproductive data,farms can fully grasp the reproductive status of the herd,significantly improve expansion efficiency,accelerate genetic progress,and optimize production benefits.Efficient management of reproductive data serves as a critical foundation for achieving refined operations and maximizing economic benefits in large-scale dairy farms., authors=FU Chang, LI

天妊娠率、参配率、受胎率及150 天未孕率等关键指标的计算方法、影响因素与提升策略,结合真实生产数据阐述其实际应用路径,并提出包括管理软件参数校准、发情揭发与孕检时效强化、同期流程优化等在内的综合改进方案。研究结果表明,通过对繁殖数据的深入解读与精准应用,牧场能够全面把握牛群繁殖状况,显著提升扩繁效率、加速遗传进展并优化生产效益。繁殖数据的高效管理是规模化牧场实现精细化运营和经济效益最大化的重要基石。, authors=付畅,
