Tukong: a rumpless indigenous chicken breed from West Kalimantan, Indonesia

SUMMARY Tukong is the rumpless indigenous chicken breed of Indonesia. Its features must be described as the basis for their preservation and improvement. The current understanding of the Tukong, including its origin, exterior traits, and production indicators, is presented in this review. As a result, the chicken feather colour varies from greenish-black, reddish-black, bluish-black, brown, and white, with a red pea-shaped comb. The Tukong is a dual-purpose breed categorised as a small-sized bird with a body weight of 1.65 ± 0.82 kg (rooster) and 1.42 ± 0.55 kg (a hen). This breed has the potential to be developed as a meat-producing chicken, which is supported by its high dressing percentage (79.50%). However, the Tukong has low reproduction properties (egg production = 8–14 eggs/6 month period, fertility = 73.51%, hatchability = 81.42–84.26%). The development of the Tukong chicken needs to be increased in order to maintain its sustainability and take advantage of its superiority to other pilot candidates for the formation of new breeds.
