Abstract Eld’s deer, a conserved wildlife species of Thailand, is facing inbreeding depression, particularly in the captive Siamese Eld’s deer (SED) subspecies. In this study, we constructed genomes of a male SED and a male Burmese Eld’s deer (BED), and used genome-wide single nucleotide polymorphisms to evaluate the genetic purity and the inbreeding status of 35 SED and 49 BED with limited pedigree information. The results show that these subspecies diverged approximately 1.26 million years ago. All SED were found to be purebred. A low proportion of admixed SED genetic material was observed in some BED individuals. Six potential breeders from male SED with no genetic relation to any female SED and three purebred male BED with no relation to more than 10 purebred female BED were identified. This study provides valuable insights about Eld’s deer populations and appropriate breeder selection in efforts to repopulate this endangered species while avoiding inbreeding.
