Abstract

Sumbawa pony in Malaysia originated from an island in Indonesia and are a crossbreed of Arabian horse and Sandalwood pony. This particular breed is internationally acknowledged because of its strong resistance to diseases and its inheritance of the Arabian horse's gait and posture. Unfortunately, no cytogenetic study has been done on this breed and their breed lines. There is no documentation that mention Sumbawa pony as a hybrid or a crossbreed species. Karyotype analysis was used to distinguish the identification of Sumbawa pony and to compare it with the karyotype of a standard horse in terms of the number of chromosomes by using Peripheral Blood Mononuclear Cell Culture technique. Karyotype is a conventional cytogenetic method that can be very useful in evaluating the species identification and also detecting any inheritance of genetic diseases. In this study, blood samples were taken from sixteen male Sumbawa ponies and were brought into the laboratory to undergo karyotyping process. Six male ponies showed 64 total chromosomes which indicate the similarity between the numbers of chromosomes of a standard horse. Among 32 pairs of chromosomes, 13 pairs are a mixture of metacentric and submetacentric autosomes, while the remaining 18 pairs are acrocentric autosomes. Thus, Sumbawa pony has shown 64 chromosomes which is similar to the standard horse thus can be classified as a breed of domestic horse (Equus ferus caballus).
