PROSTAGLANDIN F2α SUPPLEMENTED SEMEN IMPROVES LANDRACE BOARS SPERM MOTILITY

This study investigated whether the sperm motility from Landrace boars improveswhen PGF2α (Dinolytic ; 5 mg PGF2α /ml) was added to diluted semen. Boars fromone large production unit, were manually collected; semen was either enriched withPGF2α (group 1, n=38), either untreated (group 2, n=32). Total volume of semencollected, percent of motility and number of obtained doses were recorded. Thehighest sperm volume collected from the two groups is corresponding to ejaculatesfrom Landrace boars with PGF2α supplemented semen (267.6 m)l. Regardingmotility, the sperm collected from Landrace boars with PGF2α supplemented semenwas higher from the one collected from Landrace boars with untreated semen(81.37%) and very significant differences were statistically determined. Theejaculates with highest number of obtained doses is corresponding to the onescollected from boars with PGF2α supplemented semen (25.21). Only boars from thefirst group (with PGF2α supplemented semen) showed motility over 70% and even100%. The untreated semen showed motility values around 65-70%.
