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.
| Stage | Weight Range | Feed %/BW | Daily Gain |
|---|---|---|---|
| Nursery | 15–50 lbs | 5% | 0.7 lbs |
| Grower | 50–120 lbs | 4% | 1.5 lbs |
| Finisher | 120–280 lbs | 3% | 1.8 lbs |
| Sow | 300–400 lbs | 2% | Maintenance |
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.
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.
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.
