| Summary: | One of the efforts to improve quality of local chicken as a source of meat is with increase the
growth of local chickens were crossbreed between Pelung chicken with broiler chicken.
Pelung chicken cross the parent stock broiler chicken showed that the F1 hybrid has a good
weight, but the character fenotip isn not uniform. Therefore carried out cross-breeding
(backcross) between the parent F1 with Pelung chicken both males and females, but the
character of the phenotype of the chicken (BC1) is also not uniform yet. Therefore, in this
study was conducted by mating BC1 with BC1 to produce a local chicken with a stable
phenotype and genotype (BC2). After eggs of BC2 hatching, chicken weight measurements
was performed every week. Then color of his fur, the overall height, weight, tibia, thighs,
wings, back, neck and beak were observed at the end of weeks 7. The results showed that the
qualitative character of the chicken phenotype, which is the feathers produce color dark
brown and light brown. The beak all colors are yellow, while the legs are all black color
grayish. All forms was single comb and red. Based on survey results revealed that the BC2
chicken weight of 563.83 ± 109.527. These results suggest the chicken body weight lower
than parents of BC2 (BC1), which has a weight of 811.625 ± 116.627 in weeks 7. Based on
these results, it could be concluded that BC2 chicken weight lower than BC1 sires, but the
characters have a uniform phenotype.
