Effect of feathering genes on growth performance of F2 backcrosses and comparison of F1 and F2 crosses of Abor Acre broiler breeder x native chickens in humid tropical environment

This study was conducted to evaluate growth performance, brooding and rearing mortalities of F2 main reciprocal backcross progenies Abor Acre broiler breeder x native chicken crosses compare their F1 progenies. The base population used in the consisted mature (~ 48 weeks) male female chickens exotic (Abor Acre) parent stock. varieties were made up normal feather, naked neck frizzle genotypes. These birds mated stocks fashion generating crossbreds. Females these hybrids then back cock generate that evaluated present study. Data analyzed include body weight (BWT) linear parameters (LBPs), average feed intake (AFI), conversion ratio (FCR), mortalities. Comparisons between genetic groups for done by means analysis variance (ANOVA) technique. Results indicated improved performance ratios compared counterparts. individuals both superior crossbred populations. Chick mortality rates higher involving genotype other plumage types. It concluded backcrossing cocks increased profile lines resulting enhanced Crossbreeding local generated had potentials relative strains better adaptability breed. However, incubation strategies capable minimizing at embryonic, phases should be explored integrated improvement programmes use reducing genes optimal results.
