Aims: To ddetermined the effect of the addition of sweet orange essential oil for tris yolk extender to percentage viability spermatozoa in Boer Buck frozen semen.

Study Design: Randomized Block Design.

Place and Duration of Study: Sample: Laboratory Reproduction of Loka Penelitian Kambing Potong Sei Putih Indonesia, between January and March 2019.

Methodology: The research procedure starts with the preparation of semen extender, collection of fresh semen, dilution of semen, equilibration, freezing of semen, and thawing.

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 tris yolk extender. The observed variable was percentage viability spermatozoa evaluated before freezing and after freezing (Post-Thawing).

Results: The results showed that the addition of sweet orange essential oil had a very significant effect (P <0.01). The results of adding sweet orange essential oil to the extender (Post-Thawing) were 44.8% (P0), 49% (P1), 51.8% (P2), 55.2% (P3) and 59% (P4).
