Abstract

Methods for estimating the in vitro fertility quality of a semen sample for use in artificial insemination have been investigated for a long time; however, for animals with high reproductive performance, these methods still have many shortcomings. Furthermore, there have been few reports on the peculiarities of swine sperm cells, especially regarding factors that influence fertility. Thus, some characteristics of sperm integrity and functionality may serve as indicators of reproductive performance in swine. The present study evaluated the morphophysiology of spermatozoa from swine with high and low in vivo farrowing rates. Animals with high fertility had higher mitochondrial functionality (p < 0.05), lower plasma membrane fluidity (p < 0.01) and higher total antioxidant capacity (p < 0.01). The last two parameters were positively correlated with in vivo fertility (r = 0.77, p = 0.0003; and r = 0.63, p = 0.0049; respectively). These findings indicate that certain parameters affect fertility and are potentially useful factors for evaluating semen and indicating the farrowing rate in swine.
