Three loose housing systems for lactating cows (compost bedded pack, CBP; conventional bedded pack, BP; and freestalls, FS) were assessed on one farm in terms of cow behavior and welfare. An on-farm welfare assessment based on the Welfare Quality protocols was used four times every three months on 757 cows. Video recordings taken twice over four days were used to assess behavior patterns at resting areas. Cows in CBP and BP were dirtier than those in FS ( < 0.0001). Fewer integument alterations were recorded for CBP and BP than FS ( < 0.001). Cows in BP were quicker to lie down and stand up compared to those in CBP or FS ( < 0.001). Percentages of cows needing more attempts before rising were higher for FS ( < 0.01). However, a higher frequency of kneeling was observed in CBP ( = 0.033). A lower percentage of cows lying in the resting area was recorded for FS (56%) than CBP or BP (97 or 84%, respectively, < 0.05). Overall, in this study, cows kept in bedded pack barns were dirtier but had fewer integument alterations and spent more time lying down in the resting area than cows housed in freestalls.
在一个农场对三种用于泌乳奶牛的散栏饲养系统（堆肥垫料栏，CBP；传统垫料栏，BP；以及自由牛舍，FS）进行了奶牛行为和福利方面的评估。基于福利质量协议的农场福利评估每三个月对757头奶牛进行四次。在四天内进行两次视频记录，用于评估休息区域的行为模式。CBP和BP栏中的奶牛比FS栏中的奶牛更脏（<0.0001）。记录到CBP和BP栏中奶牛的体表改变比FS栏中的少（<0.001）。与CBP或FS栏中的奶牛相比，BP栏中的奶牛躺下和站起更快（<0.001）。FS栏中奶牛起身前需要更多尝试的百分比更高（<0.01）。然而，在CBP栏中观察到跪卧的频率更高（=0.033）。记录到FS栏中躺在休息区域的奶牛百分比（56%）低于CBP或BP栏（分别为97%或84%，<0.05）。总体而言，在本研究中，与自由牛舍中的奶牛相比，饲养在垫料栏牛舍中的奶牛更脏，但体表改变更少，且在休息区域躺卧的时间更多。
