The Influence of Flushing During Estrus on Ovulation and Embryo Survival to 30 Days Gestation

English workers have reported that doubling the feed from 4 to 8 lb. for one feeding after breeding tended to increase the number of ovulation sites and the number of pigs born. Workers at Kentucky have also found similar results when gilts were fed ad libitum for a 12-hour period following breeding. Previous work done at this station has failed to confirm these reports. The experiment reported here is a further attempt to substantiate this work under South Dakota conditions
