In these optimum conditions of recollection (controlled temperature, damp and brightness) a production of 1500 doses per boar and year can be got (3 million usable spermatozoon per dose), which implies an important economic interest. The module SAFE-SEMEN 2000 was introduced during SPACE 2000 in Rennes (France) and is currently commercialised in France.
Other projects finished in the ending of 2005 were the CDTI P-20030301 (2003-2005), in collaboration with UdG and UAB universities, with the title "Improvement of reproductive capacity of Pietrain boars" in which we studied the quality improvement of seminal doses from Pietrain boars through the application, on the one side, of light osmotic hits and, on the other side, filtration protocols in columns of neutral sephades. To value the effect of both methodologies, both spermatic parameters (mobility, morphology and spermatozoon serviceability, and integrity of mitochondrial clad and acrosoma) have been studied as well as the functional parameters (ORT and HRT) of seminal doses, before and after having applied osmolarity changes and filtration with sephadex columns.
It has been observed that both in the application of osmotic hits and filtration through sephadex columns, the ejaculates respond in different ways depending on spermatic quality presented before the application of protocols. In the case of osmotic hits, spermatic morphology is the only parameter which is not affected. Whereas, in the filtration through sephadex columns, all parameters go through a quality improvement, except for the results in the functional HRT test, where no significant differences between the filtered and not filtered doses are observed.
