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

Abstract

The effect of an intravenous oxytocin injection at alternate 14-day periods on milk and fat production of seven Holstein-Friesian cows during a lactation has been studied. Mean daily production per cow during the injection periods was 3.6 lb. higher than during control periods when the transition day was omitted from each period. The per cent of fat in the milk was not significantly different between the experimental and control periods. © 1954, American Dairy Science Association. All rights reserved.
