The effect of early handling of foals on their reaction to handling, humans and novelty, and the foal-mare relationship

Abstract The natural behaviour of horses in response to danger is to take flight, and consequently human handlers can be injured. Reducing the flight response and general reactivity of horses is therefore likely to reduce the incidence of injuries to handlers. In this experiment we investigated the effect of handling foals in the first 2 days after birth on their subsequent response to handling, humans and novelty, and the foal–mare relationship. Standardbred foals were assigned to one of two groups, handled (H) ( N  = 22, 12 colts, 10 fillies) and control (C) ( N  = 22, 11 colts, 11 fillies). Handling took place 3 times/day on days 1 and 2 after birth for 10 min/session. Individual foals were gently restrained and stroked all over their body using bare hands and then a plastic bag and each leg was lifted once. C foals received no handling. C and H foals did not differ in their reaction to freeze branding at a mean age of 14 days. The approach and leave behaviour of mare–foal pairs were observed at pasture during week 5 to evaluate their relationship. Mares of H foals were less active in keeping the pair together than mares of C foals (GLM: F 1,33  = 6.81; P Z  = 2.44, N  = 22, P Z  = −1.98, N  = 22, P Z  = −1.80, N  = 22, P  = 0.07). Handling of foals in the first 2 days after birth appeared to affect the foal–mare relationship and alter their perception of humans at a later age but did not alter their response to novelty or to handling. The effects of early handling of foals on the foal–mare relationship require further investigation.
