Viability of Spermatozoa in Goat's Liquid Semen after Adding Sweet Orange Essential Oil to The Andromed Extender

Aims: To find out the percentage of live spermatozoa after diluting the goat's liquid semen using an andromed extender plus sweet orange essential oil. Study Design: Randomized Block Design. Place and Duration of Study: Sample: Galang, Deli Serdang Regency, Indonesia, between December 2022 and January 2023. Methodology: The research procedure starts with the preparation of semen extender, collection of fresh semen, dilution of semen and equilibration. This  research obtained  conducted  using  a  Randomized  Block  Design  consisting  of  5  treatment  levels  and  five replications. Semen storage using 3 Bucks, which has done for three days. As a treatment is the addition of sweet orange essential oil as much as (P0) 0%, (P1) 0.25%, (P2) 0.5%, (P3) 0.75% and (P4) 1% on the andromed extender. The observed variable was percentage viability spermatozoa evaluated before equilibration and after equilibration. Results: The results showed that the addition of sweet orange essential oil had a not significant effect (P <0.01) to viability of spermatozoa. The results of adding sweet orange essential oil to the extender (after equilibration) were 80% (P0), 80% (P1), 80% (P2), 80% (P3) and 81% (P4). Conclusion: Adding sweet orange essential oil to andromed had no effect on the viability of goat spermatozoa in liquid semen.
