Summary The effects of seminal plasma ( SP ), derived from autologous, homologous and heterologous species (stallion, boar and dog) on chilled Asian elephant sperm quality, were determined. Semen was collected from eight males and samples with ≥30% motile spermatozoa were used in the study. Semen was diluted with Tris–glucose–egg yolk extender, supplemented with different SP types and preserved at 4°C for 48 hr. Experiment 1 ( n = 31), showed that the presence of SP (autologous) helped to preserve sperm quality in terms of sperm motility and acrosome integrity ( p < .05). Homologous SP did not result in better sperm quality than autologous SP . Heterologous SP from stallion provided higher sperm motility and velocities compared to autologous SP ( p < .05). Experiment 2 ( n = 14) determined the effect of different SP from four stallions. All stallion SP gave higher ( p < .05) results for motile spermatozoa and sperm velocities than autologous SP . In conclusion, the presence of SP helps preserve Asian elephant sperm quality and stallion SP supports the motility of Asian elephant spermatozoa during cold storage.
