In order to increase the genetic potential of the boars, a single seminal dose per sow oestrus has been applied, for which the performance achieved with 3 different models in semen processing (refrigeration, cryopreservation and encapsulation) has been studied. In the inseminated sows, the fertility rate and the embryo viability was evaluated at 24 days of gestation. A notable improvement was found in the percentage of embryonic vesicles with respect to the ovulation of the inseminated sows with encapsulated semen (85.43%), with respect to the refrigerated group (79.40%) and the cryopreserved group (77.78%). Semen encapsulation is shown as a technique that can offer better productive performances than the methodologies usually used.
