Teat number is an important trait in pig production since each piglet need access to its own teat, due to a complex nursing behavior between the piglets and the sow. The number of teats can vary, but fourteen is most common in the Swedish Yorkshire breed. The main aim of this paper is to understand causes of variation in number of teats. We do also investigate if a linear mixed model with residuals modeled by a generalized linear mixed model, a case of a so called double hierarchical… Expand
