A Synthetic Pabulum vs. Yolk-Citrate Buffer as a Diluter of Bull Semen

Abstract
In a trial involving 1284 field inseminations, fertility was 15% higher with semen of 19 bulls diluted with egg-yolk citrate than with other portions of the same semen diluted with a synthetic pabulum made up in accordance with the formula published by Phillips and Spitzer in 1946. The real difference between the 2 diluters may be considered as lying within the range 7-23%.
