A balanced swine ration, not a bucket of scraps
Durocs are fast-growing, heavily muscled red pigs, and they build that growth on a complete swine feed balanced for protein, energy and minerals at each stage — not on whatever the kitchen produced. The daily amount depends entirely on the pig in front of you. Growing pigs on a self-feeder eat freely, working from a couple of pounds a day as youngsters up to six or seven pounds as they approach finishing weight. Feed should be fresh in the hopper, flowing freely rather than bridged or mouldy in the corners, and matched to the stage: starter and grower feeds are not interchangeable with a sow ration.
Breeding animals eat to a number
Adult Durocs left to eat freely get fat, and overfat sows farrow poorly, so breeding stock eats to measure. A gestating sow typically does well on about four pounds of sow feed a day, adjusted by her condition — ribs felt under a smooth covering, spine not sharp, not buried. Once she farrows, the ration climbs steeply: a nursing sow with a big litter may need ten pounds or more a day, built up over the first week and split into at least two feeds so she can finish it. Boars stay leaner on a modest measured ration with exercise, since a heavy boar is harder on himself and on the sows he serves.
Water decides whether feed gets eaten
No part of the Duroc ration works without water. Pigs drink throughout the day, nursing sows most of all, and a blocked nipple drinker or an empty trough will cut feed intake within hours and milk yield soon after. Check every drinker physically each morning — look, then press it and watch it flow. In freezing weather that check matters twice a day. Feed and water points should be far enough apart that the pen floor between them stays workable, and feeders need adjusting as pigs grow so feed is available without being rooted out and wasted into the bedding.
Extras, pasture and what to leave out
Durocs enjoy rooting pasture and will take vegetables, windfall fruit and garden surplus happily, but treats should ride on top of the balanced ration in small amounts, not replace a share of it. Avoid feeding mouldy grain, rancid scraps or anything salty and processed; a pig's enthusiasm is no guide to safety. If pigs have outdoor runs, rotate or rest ground where possible, since rooted, bare pens turn feed into mud waste in wet weather and make intake impossible to judge. Weigh or tape growing pigs regularly — a Duroc's daily gain is the clearest verdict on whether the current ration and feeder setting are right.
Appetite warnings in a fast-growing breed
A pig off its feed is a pig to look at the same day: check water first, then temperature of the pen, then the animal itself. Take scouring that spreads pen to pen, coughing groups that stop coming to the feeder, a sow that refuses feed after farrowing, or any pig that cannot rise to eat straight to a veterinarian. Sudden feed refusal across a whole pen can also mean a spoiled batch, so hold the feed and smell and inspect it before offering more. Because sow, boar and grower pens all eat differently, KinsLe Care Teams let you set each pen's feeding as its own assigned duty, marked done at the time it actually happened.
