奶牛乳房炎是造成奶牛场经济损失最严重的疾病之一,干奶期是治疗奶牛乳房炎的关键时期,干奶期奶牛饲养管理及健康状况将直接影响下一个泌乳期的牛奶品质、产量及奶牛场的经济效益。本文综合阐述了选择性干奶治疗在欧洲、美国等全球奶业发达国家及地区奶牛场中的应用情况,并分析了影响选择性干奶期治疗的管理因素,针对干奶前、干奶期和干奶后期分析了不同阶段的管理操作要点,以期为指导奶牛场实际生产提供参考依据。
Mastitis in dairy cows is one of the most serious diseases causing economic losses on farms,and the dry milk period is a critical period for the treatment of mastitis in dairy cows. The feeding management and health status of dairy cows during the dry milk period will directly affect the milk quality and yield of the next lactation period and the economic benefits of the farm.This paper synthesized the application of selective dry milk treatment in dairy farms in Europe,the United States and other developed countries and regions of the global dairy industry,and analyzed the management factors affecting the selective dry milk treatment,and analyzed the operational points of management in different phases of the pre-drying,drying and post-drying periods,with a view to providing reference for guiding the actual production of dairy farms.
