Abstract

The karyotypic studies on chickens (2n= 78), duck (2n= 80), dove (2n= 76) and quail (2n= 78) demonstrated species-specific differences in total length (TL), relative length (RL), centrometric index (CI) and arm ratio (AR) values. The estimated genomic sizes (in µm) in these birds were 97.13, 89.1, 94.9 and 39.04, respectively. The information could be helpful for species identification and detecting genetic diseases. Moreover, impacts of the findings on production performance, management practices, haemato-biochemical and serological parameters, coupled with those on karyotypes in relation to the incidences of AI and other diseases in poultry farms of the Northern regions of Bangladesh have been discussed.   

Key words: Karyotype, poultry, chromosome
