A.S. Series 66-17
An experiment was designed to compare the performance of sows during pregnancy when self- fed a bulky ration or limit-fed a higher energy ration. In the fall of 1964 , second litter sows were self-fed and housed together during the breeding period. After the breeding period, the sows were divided and one group was self-fed and the other group was limit- fed 5 lb. per head daily. Limit-fed sows were given their feed once daily in open troughs. Self-fed sows had access to a round metal fee der at all times. Water was fed ad libitum and pasture was available to both groups.
