Boar semen is voluminous and ejaculated as jets or fractions of pre-sperm, sperm rich (SRF) and post-sperm rich fractions. Recent studies have reported more resilient characteristics of sperm in initial portions of SRF towards cold shock and cryopreservation. The present study was conducted to assess the quality of specific fractions of SRF, namely, first 10mL of SRF (F1) and rest of SRF (F2) in Large white Yorkshire (LWY) boar semen. Ejaculates were collected using gloved-hand technique and were subjected to quality assessments of volume, pH, sperm progressive motility, concentration, plasma membrane integrity, abnormality, acrosome integrity and sperm membrane cholesterol. Upon statistical analysis, significant differences were noticed in volume, pH, sperm concentration and sperm membrane cholesterol between fractions of the ejaculate.
