  A survey was carried out in "Kinantan Bagombak" Breeding Farm (KBBF) in Solok City-Indonesia to estimate inbreeding rate on Kokok balenggek chicken (KBC). Estimation of inbreeding rate in a small and limited population of local chickens is very important to prevent inbreeding depression. KBC is a poultry genetic resource known as song fowl from West Sumatera Province, Indonesia. This research was aimed to calculate flock composition, effective population size (Ne) and inbreeding rate (ΔF) in KBC under ex-situ population. Census was the main research method. The results showed that total number of KBC at KBBF was 528 heads. Chicken flock composition of KBC was chick (31.63%), chicken grower (27.65%) and adult chicken (40.72%). Number of breeding males (Nm) was 54 heads and females (Nf) was 161 heads. Male and female ratio (Nm/Nf) was 1:3 (33.54%). Effective population size (Ne) was 162 heads. The rate of inbreeding (ΔF) calculated for the indigenous KBC flock considering the existing flock size and management practice was 0.0031 (0.31%) indicating that the population is not at the risk of extinction. It is concluded that inbreeding depression in KBC population at KBBF was not occurred.

  Kokok Balenggek chicken is a poultry genetic resource from West Sumatera Province, Indonesia, well-known as song fowl for Minang Kabau tribes. This study was conducted in “Agutalok” Captive Breeding Farm in Solok Regency, West Sumatera Indonesia to characterize local chickens based on qualitative traits. This research was aimed to collect basic data of qualitative marker on Kokok Balenggek song fowl. Twenty one adult male of Kokok Balenggek chickens were sampled for this study. Traits studied were number of crow, feather morphology, plumage colour, skin colour, shank colour, comb type, comb colour, earlobes and wattles. The results showed that the number of crows was ranging 5-11 crows. The qualitative traits on Kokok Balenggek chicken were Taduang (4.76%), Jalak (9.52%), Kinantan (9.52%), Kinangkeh (9.52%), Sipatuang rimbo (4.76%), Kuriak padi masak (4.76%), Biriang kalek (23.81 %), Biriang pucek (14.29%), Biriang kuniang (19.05%). Overall, normal feather cover was the main plumage characteristics of Kokok Balenggek chicken populations in the study area. Yellow shanks were dominantly most frequent, followed by black shanks. All chickens studied had earlobes and had wattles. Further studies involving morphometric, production and molecular analyses are important for exhaustive characterization.

  Indonesia has four breeds of long crower chicken, well-known as Kokok Balenggek, Pelung, Bekisar and Gaga chicken. The four breeds of those Indonesian local chicken have melodious crows and frequently send to chicken singing contest by fanciers. Kokok Balenggek chicken is a singing fowl from Solok Regency, West Sumatera Province and adopted as a symbol of Solok Regency. Pelung chicken is a local chicken from Cianjur Regency, West Java Province, which has unique, high pitch and long crower. Bekisar chicken is a local chicken from Madura Island, East Java Province. Gaga chicken is a local chicken from South Sulawesi Province. The four chicken breeds have been decided by Indonesian Ministry of Agriculture in 2011 as Indonesian poultry genetic resources. This article aims to compare the phenotypic traits of long crower between the four local chickens in Indonesia.

  The present study was aimed to calculate flock composition, effective population size and inbreeding rate of Kokok balenggek chicken (KBC) under in-situ conservation area in tigo lurah district, Solok Regency, West Sumatera Province, Indonesia. A semi-structured questionnaire was administered to 55 selected households engaged in KBC farming in the study area. The results showed that total number of KBC at in-situ conservation area was 938 heads. Chicken flock composition of KBC was chick (50.31%), chicken grower (26.03%) and adult chicken (23.66%). A low male: female ratio (Nm/Nf) of 1:1.7 was observed in the KBC breed. Number of effective population size (Ne) was 206 heads. The rate of inbreeding (ΔF) calculated for the indigenous KBC flock considering the existing flock size and management practice was 0.0024 (0.24%) indicating that the KBC breed was not at the risk of extinction. It is concluded that inbreeding rate in KBC population in tigo lurah district at in-situ conservation area is not found.
