The current study was conducted to evaluate the quality of specific fractions of three Large White Yorkshire (LWY) boar semen samples. Fifteen semen samples were collected by gloved hand method as an initial 10 mL of sperm rich fraction (SRF- F1), remaining SRF (F2) and whole semen. Samples were evaluated for colour, volume, pH, sperm concentration and progressive motility. The first 10 mL of SRF of boar semen contained 25 per cent of the total ejaculate spermatozoa and was able to withstand cooling, freezing and thawing better than the spermatozoa of the bulk ejaculate. A significant difference between the fractions was observed in the volume of semen ejaculated, pH and sperm concentration across different fractions of the same ejaculate. The differences in semen fractions were attributed to the differences in the composition of seminal plasma of the initial fraction of SRF
