ABSTRACT: This study evaluated the relationship between serum
L-carnitine level and sperm parameters in young boars. Serum L-carnitine and
semen characteristics were determined for 61 young Duroc boars between the ages
of 590 and 630 days. Multiple linear regression analysis was performed to
predict total and progressive motility and the total number of spermatozoa
based on serum total L-carnitine and free L-carnitine levels. Total number of
spermatozoa was not associated with basal serum L-carnitine levels. A
regression equation was found in which both total L-carnitine levels and free
L-carnitine levels were significant predictors of total and progressive
motility (P 0.05). These results
suggest that serum L-carnitine level is an important selection parameter for
stock boars.
