Main facilities for lactating cows (A), type of maternity (B), and calf housing (C) , analyzed across different dairy production systems (LOW = 12.0 L/cow per day (7.4–14.5); INT = 18.0 L/cow per day (14.6–22.5); and UPP = 26.7 L/cow per day (22.6–32.0).

本研究针对不同奶牛生产系统，对泌乳奶牛的主要饲养设施（A）、分娩舍类型（B）及犊牛饲养栏（C）开展分析。各组对应产奶水平如下：LOW组：每头奶牛每日产奶12.0升（范围7.4–14.5升）；INT组：每头奶牛每日产奶18.0升（范围14.6–22.5升）；UPP组：每头奶牛每日产奶26.7升（范围22.6–32.0升）。
