Results of several experiments have indicated the possible effectiveness of temporary calf separations from the cow, both in bringing cows into estrus early and in some cases improving conception rate. It has been demonstrated that frequency of lactation affects the reproductive ability of the cow and it is thought these temporary separations might be involved in this manner. The technique is a part of one of the currently used research methods in estrus synchronization and appears to be useful in conjunction with the hormone treatment. This study was undertaken to determine if calf separation technique would be useful when synchronization was not being attempted.
