Good nutrition is important for lactating sows. A 15 percent protein high-energy ration containing adequate vitamins and minerals is recommended. Reduce intake of sows immediately prior to farrowing, or add bulk with one part bran or ground oats to two parts lactation ration to reduce problems with constipation at farrowing. After farrowing, gradually increase the ration so that the sow is on full feed by seven to ten days after farrowing if she has had at least eight pigs in the litter. Feed a high-energy diet during lactation to support milk production.
Heavy milk producing sows have difficulty eating enough feed to maintain their condition.
More frequent feeding, pelleting and adding fat are techniques to increase energy intake. Summary Have sows and facilities prepared for farrowing. Be present at farrowing, if possible. Keep pigs warm and dry. Prevent anemia with iron shots.
