Characterization of Local Chickens in Akwa Ibom State Using Hatch Weights

Abstract

This study was conducted to determine hatch weights of male and female local chickens in Akwa Ibom State; to evaluate the effects of hatch batch on hatch weights and also characterize local chickens in Akwa Ibom state using hatch weights. A total of 84 local chickens (60 pullets and 24 cocks) used for the experiment were purchased from Uyo, Nsit Atai, Eket and Ikot Ekpene Local Government Areas. Chickens from all localities were assembled on deep litter to generate a broad-based population for random mating. Mating ratio of males and females was maintained at 1:5 to ensure fertilization of eggs. From inception, chickens were fed growers mash (15% CP). Feed was changed to layer’s mash (16.5% CP) when 5% egg production was attained. At 4 months egg production, collection of egg for incubation commenced. Data were collected on hatch weights of male and females chicks. Means and ranges were computed for hatch batches and sexes. Significant means were separated using Duncan’s Multiple Range Test. Mean hatch weights ranged between 22.33±0.75 and 27.03±0.82. Mean hatch weight of 25.99±0.61 for males was significantly higher (P<0.05) than 24.53±0.66 for females. Hatch weights of local chickens in Akwa Ibom State are low. Hatch batches had no effects on hatch weights. Variations observed in hatch weights constitute a valuable genetic resource for breeding programmes and in designing proper conservation strategies.
