    Abstract : The aim of this study was to determine whether libido, testicular hypertrophy and reproductive competence in boars could be evaluated by selected methods of restraint. Sexual restraint of boars of 10 mts (10R) resulted in increased testicular traits, number of mounts, ejaculation rates, total sperm count, sperm motility, live sperm and normal acrosome morphology with short reaction time of 1.5±0.3 mm. Sows artificially inseminate with sperm cells from 10R boars exhibited significant improvements than the 5R boars in terms of non-return rates (NRR), farrowing rate, total piglets born alive. The results suggests that sexual restraint of boars induces testicular hypertrophy leading to significant improvement in the fertilization competence of boars.
