Relation between postpartum calf‐licking behavior and agonistic behavior against handlers by primiparous beef cows

Abstract

AbstractMaternal protective behavior in cattle husbandry settings is typically manifested as agonistic behavior against farm staff handling the calves. Investigating factors related to agonistic behavior of cows is important. Agonistic behaviors of 30 primiparous cows against farm staff handling their calves during the immediate postpartum period were observed using continuous recording. Relations between this agonistic behavior and calf‐licking behavior were also analyzed for 2 h postpartum. Agonistic behavior was exhibited by 11 cows: 10 first displayed it during the first hour postpartum, whereas one displayed it during the second hour postpartum. Cows showing agonistic behavior spent a significantly longer time engaged in licking behavior during the first 2 h postpartum than the cows not showing agonistic behavior (p < 0.05). Although cows exhibiting agonistic behavior were likely to exhibit more calf‐licking behavior, particularly during the first hour postpartum, than those not exhibiting agonistic behavior (p = 0.08), no difference was found in the proportion of time used for calf‐licking during the second hour postpartum (p = 0.61). Results suggest an association between agonistic behavior against humans and greater calf‐licking behavior in primiparous cows immediately postpartum.
