Monitor your parasite problems by analysis of worm eggs in manure and slaughter checks. Some confinement units have minimal problems with internal parasites. Several good products are available. Recommendations for parasite control are subject to change. Check carefully to see that all products used are current and that limitations on time of use prior to slaughter is observed.
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.
