Abstract: | Six-hundred-and-seven-day-old chicks were generated from Nigerian local chickens consisting of three genotypes (Normal-feathered;
Frizzled-feathered; Naked neck) and an exotic broiler breeder (Anak Titan) to evaluate growth performance for possible meat-type
chicken development. Growth parameters measured were body weight, breast girth and keel length on weekly basis for 20 weeks.
Effects of sire, dam and chick genotypes were significant (P < 0.001) on growth traits. At week 20, chickens sired by the Anak Titan weighed 1,614.82 g followed by Normal-feathered local
chickens with body weight of 1,211.32 g. Progenies of Anak Titan and Naked neck dams weighed 1,761.96 and 1,292.80 g at week
20, respectively. Among purebreds, Anak Titan weighed 35.05 g at day-old and had heaviest body weight of 2,360.29 g at 20 weeks
compared to the three local strains. The average body weights for the crossbred, Normal-feathered×Anak Titan at day-old and
week 20 were 36.39 and 1,577.63 g, respectively. This was followed by Anak Titan×Naked neck with 33.32 g at day-old and 1,514.14 g
at week 20. Sex had significant effect (P < 0.05) at weeks 16 and 20 with the males having higher mean values than their female counterparts. This study revealed that
crosses involving Anak Titan sire×Naked neck dam had highest growth performance, and there was no strain differences among
the growth performance of purebred Nigerian local chickens. |
