Analysis of Influencing Factors and Characteristics of First-tire Production Performance of Holstein Replacement Dairy Cows
摘要
Abstract
The purpose of this study was to explore the first-born performance and its influencing factors of 18 431 Holstein cows raised in a pasture in northwest China from 2018 to 2021.Through screening and sorting,the key production performance data of 2 481 cows were finally obtained.The data were divided into training set and test set with a ratio of 9∶1,and several factors in the training set were clustered by K-means clustering analysis.The results show that the early growth and development indicators have a significant impact on the first-born performance of dairy cows,suggesting that these key indicators should be focused on in the feeding management of backup dairy cows in order to improve the first-born performance of dairy cows and thus enhance the overall breeding efficiency.关键词
