Abstract:

Boar semen is ejaculated as three uneven fractions. Recent studies have reported that the spermatozoa in initial portion of sperm rich fraction (SRF) of the ejaculates are more resistant to cold shock and survive cryopreservation better than the spermatozoa in the rest of the ejaculate. The present work was carried out to assess the quality of Large white Yorkshire (LWY) boar semen fractions reared at Kerala. Semen collected with gloved-hand technique as fractions of 10 mL each (initial 10 mL of SRF - F1; rest of SRF – F2) were subjected to quality assessments of colour, volume, pH, sperm concentration and sperm progressive motility. Upon statistical analysis, significant difference was noticed in volume of semen ejaculate between boars and in pH and sperm concentration between fractions of the ejaculate.
