Is animal welfare better on smaller dairy farms? Evidence from 3,085 dairy farms in Germany

Abstract

ABSTRACT: The structural change toward larger (dairy) farms is often criticized because it supposedly has a negative effect on farm animal welfare. We investigated this criticism using cross-sectional survey data from 3,085 German dairy farms. Even though our sample was a convenience sample, it closely resembled the diverse structures of dairy farming in Germany and covered a wide range of dairy farm sizes (7 to 2,900 cows per farm, mean 122). We developed an animal welfare index (AWI) in close consultation with experts along the dairy value chain (e.g., farm animal welfare scientists, farmers, dairy representatives). Regression results showed that larger farms tended to achieve a better AWI than smaller farms in our data set. However, the effect size was small. Nevertheless, in contrast to the widespread assumption in public discussion, larger dairy herds are not necessarily associated with poorer animal welfare. In all herd size classes, we found a large variation of AWI between herds. Although this study focused on the effect of herd size, it is not the only factor affecting animal welfare levels on individual farms. Other variables that we included in the regression to describe the AWI indicate that the knowledge and skills of the farm manager and the amount of time that farms can devote to animals have a positive effect on the AWI. However, as with herd size, the effect size of other explanatory variables was small in absolute terms.
