Background: In 1980s, the first gaur x cattle hybrid (Selembu) was born in Malaysia. However the production and domestication of the animal faces many obstacles. The aim of this literature is to report the potential concept for introduction and production of Selembu through hybridization program in Malaysia. Data generated from this study will be useful to strengthen the concept for the production of Selembu for the benefit of the beef industry as well as conserving the genetics of the gaurs in the wild. Methods: Fresh semen was collected from three wild matured Malayan gaur bulls by TM-EEJ technique. The collected semen were evaluate for volume, motility, viability and concentration before undergo cryopreservation. Data on semen collection, analysis and cryopreservation were used as criteria for semen selection during AI into the cow. The conception rate was recorded in each inseminated group. Selembu calves were raised and evaluated their growth performance in farm environment. Results: As a result, we managed to collect and cryopreserve the semen from all three wild gaur bulls. The cryopreserved semen was thawed and insert into cows by AI technique. 13 out of 21 cows in the farm received the gaur semen successful pregnant with Selembu fetus. Conclusion: An improvement in farm management, animal husbandry, breeding program and conservation of wild gaur would benefit the production of Selembu in the future.
