Youngstock housing design significantly affects calf and heifer welfare during the critical pre-weaning and growing periods, with space, social housing, and environment all influencing outcomes.
Youngstock welfare shapes lifetime outcomes. Individual housing prevents social behaviour that is natural and necessary for normal development. Group housing better meets social needs but requires higher disease management vigilance. Adequate space, excellent bedding, social housing post-weaning, and protection from extremes of temperature create welfare-positive rearing environments that also produce better lifetime productive performance.
