Background and Objective: The component of the oxygen storage and regulation system is Haemoglobin in all living organisms including pigs. This study was carried out to characterize the genetic pool of the indigenous Nigerian Duroc pigs using Hb polymorphism as well as the association of the Hb variants with body weight (BW) and some biochemical traits. Materials and Methods: Blood samples were collected from a total of ninety-six mature pigs of both sexes were randomly sampled in Imo State, Nigeria The cellulosic acetic electrophoresis and specific staining procedures were used to indicate the band patterns of the Hb of which two co-dominant alleles causing the occurrence of two genotypes AA and AB were found among the pig. Results: The results obtained showed that the frequencies of A and B alleles were 0.85 and 0.15 and the corresponding genotype frequencies of AA and AB alleles in the pig population were 0.70 and 0.30 respectively. Therefore, the observed and expected genotype number was not significant at p>0.05, thus supporting the Hardy-Weinberg population. The expected heterozygosity (He) was 0.25 which is the measure of gene diversity while the Shannon diversity index (H) recorded 0.44 indicating non-assortment mating. Hb variants did not have significant effects at p>0.05 on the body weight and other measured parameters of the pigs. Conclusion: The male pigs were significantly high in all the parameters measured except for breast circumference where there was no variation between male and female Duroc pigs. However, further study should be on the use of neutral markers (Microsatellites) and Single Nucleotide Polymorphism (SNPs) to enhance national conservation and structured production of Duroc pig in Nigeria.
