Evaluation of Reproductive Performance and Egg quality Traits in Progenies of Dominant Black Strain Crossed with Fulani Ecotype Chicken

Abstract

This study was undertaken to contribute to the genetic improvement of the indigenous chicken by direct andreciprocal crossing with an exotic egg type strain Dominant Black (DB). Results indicated significant (P<0.05)effect of genotype on fertility and hatchability of eggs. Percentage fertility across the genotypes was, 73.00,76.24, 59.88 and 54.12%, while hatchability was 73.90, 78.30, 70.45 and 70.10%, for DBxDB, DBxFE, FExDBand FExFE, respectively. There was no significant (P>0.05) difference in hatch weight of the chicks. The crossbred (DBxFE and FExDB) had higher egg weight (51.45g and 51.35g vs. 47.19), total egg number for 100 days(51 and 53 vs. 40) and hen day production (50.87 and 52.47 vs. 46.05) than the pure bred Fulani Ecotype.FExDB had significantly higher body weight at first egg (1408g) than DBxFE (1388g). Mortality wassignificantly (P<0.05) higher in DBxDB than other genotypes during the laying period. Significant and nonsignificant differences existed in internal and external egg quality traits across the genotypes.
