Free Amino Acids in Ram Seminal Plasma1

J. D. Smith and E. F. Graham

University of Minnesota,2 St. Paul 55101

Abstract

The concentrations of free amino acids in ram seminal plasma were determined. Small increases in the concentration of four amino acids were found to occur when the fresh semen was incubated at 37C for 3 hours. The changes were considered to be consistent with a slow rate of proteolysis in the incubated semen. The pattern of amino acids in ram plasma was found to differ from and be more variable than that in bull plasma. The results of regression analyses of amino acid concentrations against sperm concentrations were suggested as possible indicators of differences among amino acids in their sites of origin in the reproductive tract. Some differences in amino acid concentrations were also found among rams.
