A Review Of Oxytocin Use For Sows And Gilts (2005), S K. Linneen, J M. Benz, Joel M. Derouchey, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz Jan 2005

A Review Of Oxytocin Use For Sows And Gilts (2005), S K. Linneen, J M. Benz, Joel M. Derouchey, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Oxytocin is frequently used to decrease farrowing time and birth interval as an aid to prevent stillbirths, but recent research has shown that oxytocin use can increase the number of pigs stillborn when used too early in the birth process. The research indicated that the reason for increased stillbirths was an increased number of ruptured umbilical cords, leading to compromise of the pigs' oxygen supply during the birth process. Oxytocin usage should be limited to older-parity sows and the last half of the birth order.; Swine Day, 2005, Kansas State University, Manhattan, KS, 2005
