PROSTAGLANDIN F2α SUPPLEMENTED SEMEN IMPROVES LANDRACE BOARS SPERM MOTILITY
Keywords:
PG F2α, semen, boar, sperm motilityAbstract
This study investigated whether the sperm motility from Landrace boars improves
when PGF2α (Dinolytic®; 5 mg PGF2α /ml) was added to diluted semen. Boars from
one large production unit, were manually collected; semen was either enriched with
PGF2α (group 1, n=38), either untreated (group 2, n=32). Total volume of semen
collected, percent of motility and number of obtained doses were recorded. The
highest sperm volume collected from the two groups is corresponding to ejaculates
from Landrace boars with PGF2α supplemented semen (267.6 m)l. Regarding
motility, the sperm collected from Landrace boars with PGF2α supplemented semen
was higher from the one collected from Landrace boars with untreated semen
(81.37%) and very significant differences were statistically determined. The
ejaculates with highest number of obtained doses is corresponding to the ones
collected from boars with PGF2α supplemented semen (25.21). Only boars from the
first group (with PGF2α supplemented semen) showed motility over 70% and even
100%. The untreated semen showed motility values around 65-70%.
