Abstract

We investigated whether phenotype affects vocal and behavioural responses of newly-weaned beef calves during handling situations, and whether vocal response differs between two types of handling situation. The phenotypic characteristic chosen was hair colour. Steers were classified into four groups, completely black animals (designated "Type 1A", N=121), black animals with white markings ("Type 1B", N=35), completely white animals ("Type 2A", N=114) and white-faced animals with some degree of tan or light brown body colouration ("Type 2B", N=37). In trial 1, vocalizations of all 307 steers were individually recorded for 1 minute, while each was restrained for ear-tagging, ear-implantation of a growth promotant, rectal temperature measurement, vaccination and placement of electrodes for subsequent heart rate measurement. The proportion of calves vocalizing was 36.2
