Selection for 10 Weeks Old Body-Weight on Sentul Chicken

Abstract

Sentul chicken is native chicken breed originally from Ciamis district, West Jawa. It has been a dual purpose breed which had legally claimed (decreed by Minister of Agriculture of the Republic of Indonesia, No. 698/Kpts/PD.140/2/2013, 13th of February 2013) as one of the native breeds identi ed in Indonesian. Selection on to this breed has been done for three generations with selection criteria of male 10 weeks old body weight. Selection intensity was 25% of the highest body weight. About 500 chicks were hatched per generation per line. The birds were raised intensively under optimum ration. Results showed that there were Grey- and White-lines. The average predicted response of selection based on differential and intensity selection of the grey-line male chicken were 25.55 and 37.41 g/generation, respectively. While actual and realized responses were 43.50 and 55.33 g/generation, respectively. The average predicted response of selection based on differential and intensity selection of the white-line male were of 30.23 and 40.94 g/generation, respectively, whilst predicted responses with the actual and realized responses were 38.50 and 55.33 g/generation. This exercise showed some potential bene ts of local chicken, which could be further valuable explored.
