Operation (2.5 years) of a Swedish deepbedded feeder pig production system, including nine farrowings are summarized. The system is designed to minimize pig stress and use no subtherapeutic antibiotics in the feed. Breeding and gestation occurred in a hoop building with cornstalk bedding. Conception rates and litter size were excellent. Farrowing occurred in a deepbedded remodeled building. Sows selected bedded farrowing cubicles. Pre-wean pig mortality, mostly crushing, was high (28%), occurring primarily in the first 3 days. At 2 weeks of age, the cubicles were removed and group lactation occurred. Group lactation worked well with an average pig weaning weight of 23 lb at 36 days of age. At weaning (36 days) sows were removed, and the pigs remained in the farrowing/lactation room for 24 days. Nursery phase pig growth in the deep-bedded nursery was excellent resulting in 55 lb pigs at 60 days of age and 1.22 lb/day average daily weight gain. Overall pig health was excellent with no major clinical diseases confirmed.
