The effect of milk production systems on the welfare of dairy cows has been studied worldwide, but studies that compare pasture-based, compost barn, and free stall systems, according to animal welfare, are more scarce. In this work, the welfare of 51 dairy herds, including 17 from each management system, was investigated through the application of the Welfare Quality protocol. Descriptive statistics and the Kruskal-Wallis non-parametric method were used to analyze variables. In the present work, the welfare of the evaluated herds was significantly better in the pasture-based system than in the confinement systems. However, the pasture-based system presented weaknesses in providing water resources. The compost barn had fewer animal welfare critical points than the free stall system, as well as it was better than the free stall in measures related to comfort and health. The free stall did not present better scores than the other systems. It is concluded that the welfare of dairy cows is affected by the rearing system, with better scores, in most measures, in the pasture-based system, followed by the compost barn and, finally, the free stall.
全世界都在研究产奶系统对奶牛福利的影响，但根据动物福利来比较牧场饲养、堆肥牛舍和自由牛栏系统的研究更为稀少。在这项研究中，通过应用“福利质量”协议，对51个奶牛群的福利状况进行了调查，其中每个管理系统各有17个牛群。采用描述性统计和Kruskal-Wallis非参数方法对变量进行分析。在本研究中，基于牧场的系统中评估牛群的福利状况明显优于圈养系统。然而，基于牧场的系统在提供水资源方面存在弱点。堆肥牛舍的动物福利关键点比自由牛栏系统少，并且在与舒适度和健康相关的指标方面也优于自由牛栏系统。自由牛栏系统的得分并不比其他系统高。得出的结论是，奶牛的福利受到饲养系统的影响，在大多数指标上，基于牧场的系统得分更高，其次是堆肥牛舍，最后是自由牛栏系统。
