A.S. Series 74-30
The requirements of the lactating sow for dietary energy are dependent on the level of body reserves at farrowing time and the amount and composition of milk produced. It has been reported that voluntary feed consumption and weight change during lactation are influenced by level of feeding and weight gain during gestation. Recent research has indicated that energy utilization during the reproductive cycle is more efficient with a feeding system allowing only moderate gains in gestation and an increased feeding level during lactation. the data reported herein is a summary of five trials, two of which were reported previously (A.S. Series 71-44 and 73-50). The studies were conducted to investigate the effects of restricting daily feed intake of the lactating sow to 1 lb. per pig nursing comparted to ad libitum feeding during a 21-day lactation period.
