Effect of age on the seminal plasma and spermatozoa lead concentrations of bulls.
Blood, seminal plasma and spermatozoa lead concentrations were determined in Holstein (29 animals), Brown Swiss (14 animals) and Charoleux (11 animals) bulls aged 1-8 y. Blood concentrations were (mean +/- SD) 21.47 +/- 5.85, 18.71 +/- 6.60 and 23.27 +/- 6.75 ng Pb/ml respectively/each breed. Seminal plasma concentrations were 17.15 +/- 10.37, 13.62 +/- 10.10 and 14.03 +/- 11.31 ng Pb/ml, respectively. Spermatozoa concentrations averaged 74.93 +/- 48.10, 76.60 +/- 33.95 and 63.39 +/- 25.83 ng Pb/10(9) cells respectively. Age appeared to influence seminal plasma and spermatozoa lead levels, gradually decreasing in concentrations as the animals advanced in age.
