Document Summary

At market weight, gilts are either selected to breed or go to market. Those selected for breeding are removed from ad libitum feeder and fed 6-7 lbs of feed per day. This will keep them in good gaining condition but wont allow them to get fat. If thin at breeding, they may be flushed by full-feeding for 1 to 2 weeks prior to breeding. Nutrient requirements of the pregnant sow are low, particularly during the first 2/3 of gestation. The majority of fetal development occurs during the last month of gestation. Sows should be fed at a level to accommodate growth of fetuses and placenta. Gilts should be fed to gain more of their own body weight as they have not reached mature size. Will gain about 60 pounds of their own body weight. Targeted pregnancy weight gain should be 75 to 85 lb for sows and 100 to.
