Perfil espermático de tres razas porcinas mediante tecnología microscópica en campo

Abstract

In the course of the last years, the consumption of pork meat has increased due to its high protein quality, due to this increase, the producers put more in practice the AI, therefore, the seminal evaluation of the donor pigs becomes indispensable for reproductive and productive improvement in the pig farms. The objectives of this study were: to analyse the sperm characteristics (motility, viability and morphology) of three swine breeds using the AndroScope CASA mobile computerized microscopic system, to evaluate the variability among three swine breeds in terms of sperm quality, and finally, to determine the sperm parameters of the species. According to the quality analysis, no significant statistical differences were found among the three evaluated swine breeds, however, a tendency of better semen quality was observed in the Duroc and Pietrain breeds, except for circular and local motility, since the three breeds presented higher values according to the instructions in the AndroVision instructions for the swine species. In the morphological evaluation of the three specimens, abnormalities higher than 20% were detected, which indicates that they are within the normal values for the species, being the highest percentage, whip tail, agglutination, proximal and distal cytoplasmic drop.
