This study examined the safety and productivity data analysis of a dairy farm over a 3-year period following the implementation of a Hazard Analysis and Critical Control Point (HACCP) system in 2018. The CCP was "the selection of milking cows" and the critical limit was "the withholding period has passed". No deviation from the critical limit was observed, the safety of the milk is ensured. In addition, the average daily milk yield per cow increased, while the average number of somatic cells/ml decreased. The number of cows with newly diagnosed mastitis increased, and the product excluded. These results suggest that the HACCP system had a positive effect on milk yield per cow and led to a decrease in somatic cells.
本研究考察了 2018 年实施危害分析及关键控制点（HACCP）系统后三年内一家奶牛场的安全性和生产数据分析。关键控制点（CCP）为“奶牛选择”，关键限制为“已过停乳期”。未观察到偏离关键限制，确保了牛奶的安全性。此外，每头奶牛的平均日产量增加，而每毫升体细胞的平均值下降。新诊断为乳腺炎的奶牛数量增加，并将不合格产品排除。这些结果表明 HACCP 系统对每头奶牛的产奶量有积极影响，并导致体细胞数量减少。
