A pig in winter is an animal wearing almost nothing. Apart from a few hardy, hairy breeds, pigs have sparse coats and rely on shelter, bedding and body fat rather than insulation they grow themselves. Young pigs and lean growers feel cold first; even mature sows burn noticeable amounts of feed simply holding their temperature on a frosty night. Healthy winter pigs therefore come down to three things working together: somewhere dry and still to sleep, enough food to fuel warmth, and someone actually looking at them properly twice a day.
A shelter pigs can burrow into
Give pigs an arc or sty with the entrance turned away from the prevailing wind and no gaps at pig height funnelling a draught across the sleeping area. Bed it deeply with straw — genuinely deep, so a pig can disappear into it with only ears and snout showing. Burrowed into dry straw, pigs create a warm microclimate together and huddle contentedly; on thin, damp bedding they pile restlessly, chill, and become vulnerable to coughs and scouring. Top the straw up little and often rather than letting it compact into a cold mat, and clear out the wettest patches near the entrance where traffic churns them. Position outdoor arcs on your driest ground and move them before the gateway turns into a wallow of mud.
Feeding for warmth, not just growth
Cold pigs eat more, and that is correct behaviour rather than greed: fermentation and body condition are their central heating. Increase rations as hard weather sets in, especially for outdoor pigs, youngsters and nursing sows, and make changes gradually over several days. Keep feeding areas as dry as you can manage — feed scattered on frozen or muddy ground is wasted and fouled — and use troughs or a clean hard standing where possible. Watch body condition by eye and hand: pigs should carry a smooth covering over the ribs without looking either tucked-up and hollow or over-fat and sluggish. A pig that leaves feed in winter is a pig telling you something, whether that is cold, bullying at the trough or the start of illness.
Water, ice and frozen ground
Pigs will not break ice for themselves and cannot go without water because their feed is dry. Check drinkers and troughs at every visit in freezing weather, break ice properly rather than leaving a skin to refreeze thicker, and clear frozen pipes or buckets as part of the morning round. Frozen, rutted ground is hard on feet and legs, so watch for pigs mincing across icy ruts, favouring a leg, or developing cracked, sore skin around the feet. Mud itself is less of a problem to a pig than cold wet bedding, but gateways and feeding spots that never dry deserve hardcore, slabs or a move to fresher ground before they become injury traps.
The checks that catch trouble early
Look for the pattern of the group, not just individuals. Healthy winter pigs emerge keenly at feeding time, eat with noise and appetite, then settle back into the straw. Shivering that does not stop after feeding, pigs huddled in a tight pile all day, coughing that spreads through the group, scouring, or one animal standing apart and off its food all deserve attention the same day. Run your hands over backs and ribs when you can — condition slips quietly under a dirty, winter coat — and keep a note of who looked off and when, so a second look tomorrow is a comparison rather than a guess.
Sharing the winter workload
Winter pig keeping is a twice-daily commitment in the dark weeks, and it runs best when it does not rest on one person's memory. Those morning and evening rounds — ice broken, straw topped up, appetites checked, troughs filled — can be assigned to whoever is on duty through KinsLe's Care Teams, with each completed job timestamped so the next person knows exactly what has already been done.
