  Kokok Balenggek chicken is one of the rare indigenous chickens in Indonesia. They are unique as they produce a melodious song like crow. They have syllabic diversity, as each portion of the call can be composed with different pitches and vocalizations. The identification and characterizations of local adorn chicken is very important for animal conservation. A research was conducted in west Sumatera to identify the genetic variability of the external genetic characteristic of Kokok Balenggek chicken. This research was conducted in a limited area of Solok district West Sumatera, Indonesia. About 203 (111 males and 92 females) Kokok Balenggek chicken were observed. The varieties are based on base colour of feather, colour of the plumage, flick feather, pattern of feather, shank colour and comb types. The method were used to analyze the rate of purity and native gene, the frequency of autosomal and sex-linked of the genes, feather pattern, rate of introgression from the exotic breed of Rhode Island Red, White Leghorn and of Barred Plymouth Rock. The research showed that the highest controlling genes characteristic external of kokok Balenggek chicken are coloured (ii), wild type pattern (e+), plain feather (ss) golden flick feather (ss), yellow shank coloured (Id_) and single comb (pp). A constitution on external genetic characteristic of Kokok Balenggek is ii e+_bbssId_pp. while The purity gene of Kokok Balenggek chicken has only 45.30%. Its genetic introgression is affected by the exotic breed from Europa and America with genetic introgression value of 0.5470. According to the rate of heterozygosity value of kokok Balenggek chicken varied within 29.41%. In conclusion, the Kokok Balenggek chickens show heterogeneity in the external genetic. To complete a set of their characterization further studies are needed on their quantitative traits and the molecular composition.

  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.
