Characteristics of production, reproduction, and sperm quality in Tukong, a rumpless chicken breed from Indonesia

Information on the production and reproductive performances of local chickens is crucial for thedevelopment of genetic improvement as well as for fostering poultry industry resilience. Withlimited data available, this study aimed to analyse the production and reproduction of Tukongchickens, a variety of chicken known for its rumpless, originating from West Kalimantan,Indonesia. Two hundred five Tukong chickens, comprising 153 hens and 52 roosters, were raisedunder intensive management for the study. The collected data included egg production, repro-duction traits, and rooster sperm quality. The average body weight of the hens was1140.55 ± 260.78 g, while the roosters weighed 1434.16 ± 387.43 g. Other production traits, suchas first egg weight, number of eggs per clutch, number of clutches per year, average eggweight, and hatching weight, were lower compared to other local chicken breeds in Indonesia.The female chicken had its first egg laid at 241.64 ± 24.65 d, with a fertility rate of 75.34 ± 1.43%and a hatchability rate of 83.05 ± 1.28%. All parameters related to sperm quality in Tukongchickens fell within normal ranges. The findings of this study suggest opportunities for further-ing breeding improvements for the Tukong chicken
