我国奶牛生产性能测定技术研究进展OA北大核心CSTPCD

The Dairy Herd Improvement technology,through comprehensive recording and measurement of milk production,milk composition,and other production data,is used to monitor changes in milk performance,mastitis health,nutrient balance,and issues related to reproductive performance.This assists in enhancing the level of dairy farming,unlocking production potential,and increasing economic benefits.The dairy cow performance testing technology in our country has become increasingly advanced,but there are still issues such as non-standard sampling methods,insufficient intelligent equipment,and inadequate utilization of DHI reports.This article discusses the current application of the Dairy Herd Improvement technology and the main problems covering this issue in China,giving advice from the aspects of optimizing sampling methods,applying intelligent technology,developing new indicators and implementing genetic evaluation systems,so as to provide references for fully understanding of the technology and improving the production performance of dairy cows.
