摘　　要：本文基于对西北地区某规模化娟姗牛场在2023年至2024年近5个月的测定数据及牛群基础资料进行了全面收集。通过运用CNDHI和Excel软件,对该牛场的乳指标、胎次、泌乳天数、305d奶量、脂蛋比、尿素氮及体细胞数等多项关键指标进行了综合分析。结果发现,该牛场在2023-2024年的乳脂率、脂蛋比、乳尿素氮和体细胞指标整体上呈下降趋势,5月份测定中头胎奶牛的比例和泌乳天数超过200天的牛只占比较高,且存在部分牛只阶段性脂蛋比和尿素氮异常的情况。This article comprehensively collects the measurement data and basic information of a large-scale Jersey cow farm in Northwest China from 2023 to 2024 over a period of nearly five months.By using CNDHI and Excel software,a detailed comprehensive analysis was conducted on various key indicators such as milk indicators,parity,lactation days,305 milk volume,fat-protein ratio,urea nitrogen,and somatic cell count for the whole year of the cow farm.Through systematic data analysis,it was found that the milk fat rate,fat-protein ratio,milk urea nitrogen,and somatic cell indicators of the cow farm generally showed a downward trend in 2023 to 2024.In the May measurement,the proportion of first-calf cows and the proportion of cows with lactation days exceeding 200 days were relatively high.Additionally,there were some cows with abnormal fat-protein ratio and urea nitrogen at certain stages.
