Abstract
Milk production is a major factor affecting the weaning weight of a calf. Researchers became interested in studying the effects of milking characteristics of the cow on the weaning weight of the calf. The interest in the relationship of milk production to calf growth has demanded that accurate estimates of milk production be obtained in the beef cow. In an effort to standardize collection methods, techniques are being studied at Nebraska to determine if the use of exogenous oxytocin will supply estimates with a small amount of variability.
The Nebraska Research Station has developed a preliminary method of collecting milk production data involving the use of oxytocin. This study was designed to provide a more critical evaluation of the preliminary estimation method being used.
The purpose of this experiment was to evaluate the effects of oxytocin on milk consumption and on total milk production. The treatments used were: A – no oxytocin; B – 40 U.S.P. units of oxytocin injected intramuscularly after the calf nursed; and C – 40 U.S.P. units oxytocin before the calf nursed.
