Table 2 Distribution of herds classified into different welfare categories by two models using welfare indicators associated with animal-based measurements. The parameter sets were applied to 55 Swedish dairy herds involved in a study on dairy cow welfare in 2005. The gold standard consisted of 9 animal-based measurements, where herds with no welfare remarks above the 90th percentile were regarded as having good welfare, and herds with ≥ 2 welfare remarks above the 90th percentile were regarded as having poor welfare.

From: Can pre-collected register data be used to identify dairy herds with good cattle welfare?
