Frequently Asked Questions

Q

How much feed does a pig eat per day?

Feed intake depends on weight and growth stage. A grower pig (50–120 lbs) eats about 4% of body weight daily. A finisher (120–280 lbs) eats about 3%. An 80 lb grower eats about 3.2 lbs per day.

  • Nursery (15–50 lbs): 5% of body weight = 1–2.5 lbs/day
  • Grower (50–120 lbs): 4% = 2–5 lbs/day
  • Finisher (120–280 lbs): 3% = 3.6–8.4 lbs/day
  • Gestating sow: 2% = 6–8 lbs/day
  • Lactating sow: up to 12–15 lbs/day

Q

What is feed conversion ratio (FCR) for pigs?

FCR measures pounds of feed needed per pound of weight gain. Nursery pigs have the best FCR at 1.5:1. Growers average 2.5:1, and finishers average 3.5:1. Lower is better and more efficient.

  • Nursery: 1.5:1 FCR (most efficient)
  • Grower: 2.5:1 FCR
  • Finisher: 3.5:1 FCR (least efficient)
  • Genetics affect FCR significantly
  • Modern breeds average 2.6:1 overall birth to market
Q

How long does it take to raise a pig to market weight?

From weaning (15 lbs at 3 weeks) to market weight (280 lbs), it takes about 5–6 months. From a 50 lb feeder pig, expect 4–4.5 months to reach 280 lbs with proper nutrition and genetics.

  • Weaning to market: 5–6 months
  • Feeder pig (50 lbs) to market: 4–4.5 months
  • Market weight: 250–300 lbs (280 typical)
  • Daily gain of 1.5–1.8 lbs in grower/finisher stage
  • Heritage breeds may take 7–9 months
Q

How much does it cost to feed a pig to market weight?

At $0.18/lb for feed, raising one pig from 50 lbs to 280 lbs costs roughly $145 in feed. Total feed needed is about 805 lbs (230 lb gain × 3.5 FCR). Feed is 60–70% of total production cost.

  • Feed cost: $0.15–0.25/lb depending on ingredients
  • Total feed per pig: ~800 lbs from 50 to 280 lbs
  • Feed cost per pig: $120–200 depending on prices
  • Feed is 60–70% of total pig production cost
  • Pasture and food scraps can reduce feed cost 20–30%
