ABSTRACT
Observation on carcass and carcass' cuts of F1 crossbred of Pelung x Kampung chickens influenced by dietary protein (15%, 17%, 19%, and 21% crude protein=CP) was carried out at the Research Institute for Animal Production, Ciawi Bogor. There were 360-day-old chicks of the crossbred, allocated to 9 dietary-protein treatments. The treatments were P1 (21%-17% CP), which was the ration with 21% CP given to chicks aged of 0-6 weeks, then continued with 17% CP ration up to 12 week of age; P2 was 21%-15% CP; P3 was 19%-19% CP; P4 was 19%-17% CP; P5 was 19%-15% CP; P6 was 17%-17% CP; P7 was 17%- 15% CP; P8 was 15%-19% CP and P9 was 15%-15% CP. At 6 and 12 weeks of age each two out of 10 birds per cage were randomly picked for carcass and carcass portion analysis. Results showed that carcass and wings of 6 weeks of age birds were not significantly (P>0.05) influenced by dietary protein, whilst breast and thighs & drumsticks were significantly (P<0.05)>
Key words: F1 crossbred of Pelung x Kampung chickens, dietary protein, carcass and carcass' cuts
