摘要
本文以湖南省4家规模化奶牛养殖场2023年的DHI数据为基础,从生产性能、乳房健康、繁殖、日粮等几个方面对全省奶牛产业生产现状进行了分析。结果发现,湖南省牛场普遍存在产奶水平较低、部分牛场乳房炎感染情况严重、牛群繁殖效率较低、牛群胎次分布和日粮结构不合理等问题,严重影响牛群生产水平及牛场经济效益。针对上述问题,本文提出了建议与对策。
Based on the DHI data of 4 large-scale dairy cattle farms in the province in 2023,this paper analyzes the production status of dairy cattle industry in the province from several aspects such as health,breeding,and diet.The results found that cattle farms in our province generally have problems such as low milk production levels,serious mastitis infection in some cattle farms,low reproductive efficiency of cattle herds,unreasonable distribution of cattle herds and dietary structure,which seriously affects cattle herds.Production level and economic benefits of cattle farms,and suggestions and countermeasures were put forward for the above issues.
