Suitability of semen stress tests for predicting fertilizing capacity of boar ejaculates

Cold- and heat-resistance were dependent factors and sperm motility but neither semen stress test can be used as a sole test for predicting the fertilizing capacity of boar ejaculates.

The first PIC408 tested with the Fertiboar innovative technology arrive to the Riufred GTC

The choice of the GTC of Riufred, with the largest census in Europe, is determined by PIC's commitment to large populations of boars with a high genetic index.

PIC increases its boar semen supply chain with the expansion of Riufred GTC, the largest boar stud in Europe

The expansion will have a new building that will have capacity for 264 additional boars.

Semen doses characteristics: volume, concentration, and preservation

We continue with the series of articles in which swine reproduction and artificial insemination specialist, Javier Gil, gives us key points about proper management to improve fertility and prolificacy. In this article we will detail important aspects about semen doses and their storage.

Improvement of the motility of boar sperm after cryopreservation

When using thawing extender at pH 8, there was enhanced post-thawing sperm motility and preservation of motility as storage time advanced.

Impact of sperm concentration on sperm morphology

Ejaculates with a high sperm concentration contain a large number of sperm, but have a smaller volume than ejaculates with a lower sperm concentration.

Effect of boar seminal dose type: cervical compared with post-cervical insemination

Post-cervical artificial insemination doses took less time than cervical doses to reach the desired temperature, but sperm quality was similar for CAI- and PCAI-doses during storage.

60% of 333 users believe that semen doses rotation is useful, but is it really?

Some routines are widely used on the daily work of pig farms and we can even think that there is some good logic behind them, but have they been scientifically tested?

Post-thaw boar sperm motility is affected by prolonged storage of sperm in liquid nitrogen

The fact that the major phenotypic characteristic of boar spermatozoa, motility, is constrained by time of cryostorage should be considered when building cryobanks of pig semen.
