Factors affecting temperament in Zebu and Friesian-Zebu crossbred cattle

Abstract

The influence of breed, sex, season, age, body weight and body condition on temperament in progeny from purebred and crossbred dairy cows was investigated. All variables, except age, had significant (P<0.05) effects on temperament. Progeny of crossbred dams had lower temperament scores than those of purebred Bunaji dams. Male animals had higher temperament and so were animals with better body condition. Temperament was lowest in the hot, dry season. Phenotypic correlations between measurements and temperament were positive and significant (P<0.05), with vigour of movement having the highest correlation with the overall temperament score. Liveweight was negatively correlated with temperament, while there was a positive correlation between temperament and body condition. Regression equations for predicting overall temperament using vigour of movement are presented.
