Abstract
Identifying and studying local chicken genetic resources in Indonesia is critical for conservation, and improving chicken breeding initiatives. The objective of this study was to determine the morphometric characteristics of Tukong chicken offspring in West Kalimantan related to finding the genetic variation and its relationship among chickens that was spreading in Indonesia. This study used 203 chickens (73 males and 130 females) of six chicken breeds: Nunukan, Tukong, and Kampung from Kalimantan, Merawang from Bangka Belitung, and two populations from Java: Tukong_like and Kampung_like. All chickens were included in the observation and measurement. The morphological data were tabulated and analyzed with descriptive statistics. The morphometric data were used for one-way analysis of variance to test the effect of breeds on body measurement in chickens. In total populations, the majority of chickens have red comb color (95%), colored feathers (92%), and read earlobe color (87%) whereas around 50% of the chicken did have a yellow shank color (49%), yellow beak color (50%), orange eye color (42%) and a single comb type (50%). The population effect on BW and morphometric traits significantly differed (p<0.05) in both male and female chickens. In both sex groups, the Tukong had the lowest BW (male = 1.59+-0.23 kg, female = 1.29+-0.21 kg), whereas the Kampung from Java had the highest BW (male = 2.66+-0,44 kg, female = 2.08+-0.30 kg). All female groups are smaller than the male groups in all six chicken populations, except for BcL (in Nunukan chicken) and BeL (in Merawang chicken). The male Tukong had the lowest results in all measurements except in BrL. Meanwhile, female Tukong only had the lowest point of the five traits (BrC, BcL, WL, BeL, and BW). Tukong chickens have lower morphometric measurements than the other five local chickens. There is a mixed value between Kampung from Java chickens and Tukong from Java chickens, indicating that there is interbreeding betwe
