Variations in growth performance traits and economic analysis of two Nigerian indigenous chicken strains and their crossbred

Abstract

This study was undertaken to compare growth performance and economics of production of two Nigerian indigenous chicken strains andtheircrossbred.The parent lines of theNigerian indigenous chicken population used consisted of two strains, the normal feather (NF)and the naked neck(NN),obtained from pure bred strains of Nigerian indigenous chickens maintained at the Directorate of University farm, Federal University of Agriculture, Abeokuta, Nigeria. Three genetic groups comprising a combination of NF male X NN female (GG1), NN male X NN female (GG2) and NN male X NF female (GG3) were used for the study. The results revealed that though chicks from GG2 were heavier (P<0.05) than others at hatch, those from GG3 had higher specific growth rate (4.36 and 5.59% greater than values obtained for GG1 and GG2 respectively) which translated to heavier body weight (1116.55g) at 12 weeks of age. Quantity of feed consumed was similar (P>0.05) among the three groups. Birds from GG3 were however, able to utilize feed consumed by 11.21 and 12.93% more efficiently than GG1 and GG2 respectively. Feed cost per kg weight gain was least for GG3 ( 520) with gross margin of 132.35 and 133.43 above GG1 and GG2 respectively. GG3 had the best profitability index and return on investment. Crossbreeding naked neck and normal feather showed superiority in growth and economic returns and is therefore recommended in breeding/production programmes targeted at expanding Nigerian indigenous chicken production.
