Genetic diversity of poultry chicken types reared in Ogun state using albumin polymorphism

Abstract

The study was carried out to examine the genetic diversity in different chicken types reared in Ogun State using Albumin. A total of 80 birds which include: 25 broilers, 25 layers and 30 indigenous chickens from Abeokuta North, Ado odo Otta, Sagamu and Ijebu Imushin were purposely sampled. 5mL blood samples were drawn per individual from the wing vein via 2mL hypodermal needle into anticoagulant treated (heparinized) vials. Albumin polymorphism was investigated using cellulose acetate paper electrophoresis. Based on the estimate allele frequencies the population was characterized by their genetic distance (D) among the populations. The estimates of heterozygosity were 0.28, 0.40, and 0.55 for layers, broilers and indigenous chicken populations. Two alleles were reported for each of the population (A and B in Albumin). The closest genetic distance relationship was found between the indigenous and layers chicken populations (D=0.0038), while population from broilers and indigenous were more genetically distance (D=0.8948). The relationships among the chicken population were consolidated by the dendrogram that emanated from their genetic distance. The result obtain will be useful as an initial guide in defining objectives for future investigations of genetic integrity and developing conservation strategies for chicken species.
