Kommisrud E Paulenz H Sehested E Grevle IS Influence of boar and semen parameters on motility and acrosome integrity in liquid boar semen stored for five days. Acta vet. scand. 2002 43 49-55. - Ninety ejaculates from a total of 76 AI boars were extended in Beltsville Thawing Solution BTS . Boar identity breed weight of the ejaculate and sperm concentration were registered. Motility and acrosome integrity were assessed after storage at 16-18 C for 6 30 54 78 and 102 h. Storage time had a significant influence on both motility p and acrosome integrity p . The Least Square Means for percentage of motility showed a small decline from after 6 h of storage to at 102 h. Motility at 78 and 102 h was significantly different from motility at 6 h p . The percentage of sperm cells with normal acrosomes declined throughout the experiment. The Least Square Means for 6 30 54 78 and 102 h of storage were and respectively. The decrease in acrosome integrity from one storage time to the next was highly significant throughout the trial p . There was a significant influence of boar p and sperm concentration p on motility while acrosome integrity was affected only by boar p . Breed of the boars and weight of the ejaculate did not influence the dependent variables. longtime storage sperm concentration. Introduction In Norway artificial insemination AI in pigs is performed with liquid semen extended in Beltsville Thawing Solution BTS Aalbers et al. 1983 . Extended semen is distributed to the whole country from one .
