Breeding stallions in AI programs face specific welfare considerations related to collection frequency, housing, social needs, and management of reproductive pressure.
Breeding stallions in intensive AI programs face welfare challenges related to social isolation, restricted expression of natural reproductive behaviors, and collection frequency that may exceed physiological optimum. Stallions are highly social animals with complex behavioral repertoires that individual housing prevents them from expressing. Providing fence-line social contact, appropriate exercise, environmental enrichment, and monitoring for stress indicators improves stallion welfare in AI programs. Collection frequency should be managed to maintain semen quality and avoid physiological depletion.
