The laboratory examination of semen quality parameters is an indirect way of assessing male fertility. The objective of this research was to study the semen quality parameters of Large White Yorkshire (LWY) boar ejaculates, which had the minimum sperm progressive motility necessary for being selected for further processing. The pigs were maintained at the Centre for pig production and research, Mannuthy, Kerala. A total of 24 ejaculates were collected from seven boars using gloved hand technique. The collected semen was examined for volume, colour, pH, sperm concentration, progressive motility, viability, abnormality, acrosome integrity and functional membrane integrity. Gel free volume differed significantly between boars. | Fresh semen characteristics of large white yorkshire boar semen selected for liquid semen preservation
