Genetics of behaviour in cattle

Abstract

Behavioural genetics is an important area of research, because the behavioural repertoire of domestic animals is so rich and complex, with striking similarities and differences between species and all of its effects on animal welfare and productivity. This review is directed on the genetics of behaviour, we explain how behavioural genetics can be used in breeding programmes and to learn more about the genetic variation in these traits. It includes examples from dairy cattle as well as beef cattle and illustrates the need for comparative studies. We provide an overview of studies on cattle that emphasises an inter-individual variability and a relative intra-individual consistency in fear responsiveness and discuss problems that may hinder the genetic evaluation and the application of temperament traits for genetic selection.
