Horse Winter Welfare: Managing Cold, Mud, and Restricted Grazing

Winter presents specific welfare challenges for horses, including cold stress, mud fever, restricted grazing, and increased stabling time. Proactive management is essential.

Key Facts

Horses are well-adapted to cold — they begin to feel cold below their thermoneutral zone (around 5°C for unclipped horses)
Mud fever (pastern dermatitis) is a bacterial skin infection that causes pain and lameness in wet, muddy conditions
Extended stabling during winter significantly restricts movement and social interaction
Horses without adequate roughage during cold weather cannot generate sufficient body heat from fermentation
Water sources must be checked twice daily in freezing conditions — dehydration in winter is a common welfare risk
Winter weight loss is a welfare concern in older horses, those with dental disease, and horses competing with dominant companions at feeding

Welfare Considerations

Winter welfare for horses requires proactive management rather than reactive crisis response. Cold stress, mud fever, dehydration from frozen water sources, and social isolation from extended stabling are all preventable welfare problems. Adequate hay or haylage provision is the single most important winter welfare measure — it provides warmth, satisfies foraging drive, and maintains gut motility. Rugging decisions should be based on the horse's condition and coat rather than owner preference for convenience. Regular body condition scoring during winter detects declining nutrition before it becomes critical.

What You Can Do

Provide ad libitum hay or haylage during winter to maintain body temperature and gut health
Check water sources twice daily in freezing conditions — use heated buckets or water heaters
Implement a mud fever prevention protocol: keep lower limbs dry and inspect regularly
Monitor body condition score monthly through winter — weight loss in cold weather accumulates quickly
Maximise turnout time even in winter — movement and social contact are welfare necessities
