The Effect on Milk and Fat Production of Injections of Oxytocin at Alternate 14-day Periods during Lactation

Abstract
Seven Holstein-Friesian cows were studied during one lactation. Mean daily production per cow during the injn. periods was 3.6 lb. higher than during control periods when the transition day was omitted from each period. The percentage of fat in the milk was not significantly different between the exptl. and control periods. Oxytocin as admn. in this study appeared to have no effect on reproduction.
