Effect of Sperm Losses in Semen Collection Equipment on Estimated Sperm Output by Bulls

Department of Animal Husbandry, Cornell University, Ithaca, New York

ABSTRACT

Microscopic examination of the fluid adhering inside the rubber lining and cone of the artificial vagina following semen collection reveals the presence of many sperm. If this loss is substantial it would appreciably reduce the sperm available from sires used in artificial to insure that semen is deposited as close to the collection tube as possible. In experiments designed to predict testicular sperm production in comparison with actual sperm output, the losses in the collection equipment should be measured and added to sperm numbers obtained in the collection tube to more accurately reflect actual sperm output.
