INITIATION OF SELECTION IN SENTUL NATIVE CHICKEN: TEN WEEKS GROWTH RATE

Sentul chicken is one of native chicken breeds in Indonesia, which is originally raised by villagers in Ciamis district, West Jawa Province. Sentul chicken has specific grey plumage and medium fighting cock posture. The initiation of study on improving productivity of indigenous chicken in Indonesia, especially for growth rate has been carried out using 54 roosters and 164 hens of Sentul chicken (P 0). First selection (G0) was conducted using selection criteria of the highest 10 weeks bodyweight of male chicken, so it resulted in 16 G0 roosters and 64 G0 hens were mated artificially. Ten roosters and 20 hens randomly selected to be used as control population (C0). The fertile eggs of G0 and C0 were incubated in IRIAP facilities. The offspring (SF1 and CF1) were raised in colony cages placed inside the brooder building provided with heating lamps. Feed and drinking water were provided ad libitum. Results showed that the 10 weeks old male and female SF1 reached 1154 ± 170 g/bird and 953 ± 175 g/bird, respectively. Whilst the male and female CF1 were 1054 ± 141 g/bird and 936 ± 150 g/bird respectively. Ten weeks food consumption of SF1 was 2602 ± 383 g/bird with feed conversion ratio (FCR) of 2.565 ± 0.364. The 10 weeks food consumption of CF1 was 2649 ± 434 g/bird with FCR of 2.767 ± 0.410. The results showed that there was an increase in bodyweight of the offspring both selected and control population. Carcass and carcass cuts are also discussed.
