Condition and forage: the two foundations
Winter health in cattle is mostly decided before the cold arrives. Cows going into winter carrying good condition, on feet that have been checked and with any lame animals treated, cope with months that undo a herd that starts thin. Forage is the engine of the whole season: cattle generate their warmth digesting fibre, so a plentiful supply of decent hay or haylage, offered so every animal in the group can eat at once, matters more than any supplement. Watch the quieter, lower-ranking cows at the feeder — they are the ones who lose condition invisibly behind the dominant animals — and split groups or add feeding space if the same faces are always waiting. Sorting the herd into groups by need before the weather turns, rather than mid-winter when handling is miserable, makes every later job easier.
Water, shelter and the lie of the land
Cold alone rarely troubles cattle; wet combined with wind strips condition fast. A hedge, woodland edge or simple field shelter that breaks the prevailing wind, plus a dry lying area, will do more for a wintering herd than most interventions. Water needs a daily plan: troughs freeze, and cattle that cannot drink properly will not eat properly either, so ice-breaking or an insulated supply has to happen every single day, however grim the morning. Mud is the season's slow tax — gateways, trough surrounds and feeding areas churn into a soup that cakes legs, leaves calves standing cold and spreads foot problems — so move feeders, lay hardcore or matting at pinch points, and rest the worst ground rather than letting the whole herd stand in it day after day.
If the herd comes indoors
Housed cattle swap mud for air as their main risk: a shed should feel fresh, with air moving above the animals but no draught at lying height, and enough dry bedding that knees come up clean when a cow rises. Crowding is the quiet multiplier of every housed problem, from coughs spreading through the group to bullying at the feed barrier, so stock to the shyest animal's comfort rather than the shed's theoretical capacity. Scraping passages, refreshing bedding and checking water bowls become daily fixtures indoors, and a shed that is hard to keep clean is telling you it is overstocked. Whether the herd winters out or in, the principles repeat: dry lying, moving air, and feed and water every animal can reach.
Watching the herd: the daily once-over
Winter checks are about catching drift before it becomes decline. Walk the group slowly enough to see each animal rise, walk and come to feed: a cow standing apart, hanging back from the bale, coughing repeatedly, scouring or dropping condition while her herdmates hold theirs is telling you something early. Feet deserve particular attention in wet months — lameness that starts as a cow slightly short on one leg worsens quickly in mud — and any animal off her feed entirely, breathing hard, or down and unable to rise is a vet call the same day, not a wait-and-see. Keep notes as you go: condition by group, treatments given, bales opened, problems spotted. Those winter records earn their keep at spring turnout and at every vet visit in between, and KinsLe's Pet Passport keeps each cow's checks, condition notes and vet history together in one packet you can hand to the farm vet on the yard.
