This study aimed to evaluate the effect of fish oil addition to semen extender on the quality of boar spermatozoa during 24-hour storage at 15°C. Fresh semen was collected from a healthy adult boar with initial motility ≥70% and diluted using a glukosa–sitrat–EDTA extender supplemented with 0 g (P0), 0.15 g (P1), 0.30 g (P2), and 0.45 g (P3) of fish oil per 1.000 mL. The experiment was arranged in a completely randomized design (CRD) with four treatments and four replications. Parameters observed included motility, viability, abnormality, and semen pH after 24-hour storage. Analysis of variance showed that fish oil addition had a highly significant effect (P<0.01) on sperm viability, but no significant effects (P>0.05) on motility, abnormality, or pH. The highest viability was found in P1 (93.25%) and the lowest in P3 (82.00%). Motility and abnormality improved at low doses but declined at higher concentrations. The pH values remained stable (6.7–7.2) across all treatments. In conclusion, adding a low dose of fish oil (0.15 g/1.000 mL) effectively maintained spermatozoa quality without altering extender chemistry, suggesting its potential as a natural additive for semen extender formulations in tropical artificial insemination programs.
