Abstract

Four Fp and backcross populations derived from matings between the Nigerian fowl and a strain of the exotic, gold-link chicken, were evaluated for growth and 100-day egg production. Experimental birds were raised and housed in cages to 3*+ weeks of age. The exotic backcross (EBX) population topped the other groups ( P ^ 0 , 0 5 ) especially in growth characters and egg weight. The local back- cross (LBX) was the least in performance in all traits except feed consumption, age at first egg and egg number in which it had an advantage over the other g enotypes. Body weights at 20 weeks were 9 5 *+ . *+ 8 g , 1122.66g, 10*+5.65g and 10*+l.*+2g for the LBx, EBX, RF2 and MF2 genotypes respectively. The hen-day egg numbers and egg weight of the groups were 51.38 eggs and ^ 3.6 5 g ; *+9.20 eggs and 50.59g; 51.65 eggs and *+5.8*+g, and *+8.89 eggs and *+6.37g respectively. In view of these differences, suggestions were made towards involving the crosses in further breeding and selection for the development of new breeds well adapted to Nigerian conditions.
