Abstract :

Inter and intra specific variation among muscovy duck ecotypes from three agroecological zones
of Nigeria were studied The work evaluate the morphological variation of three ecotypes ( rainforest ecotypes,
humid or guinea savanna and dry savanna ecotypes) covering southern or coastal region, central and
northern part of Nigeria. Twelve morphological traits including weight were considered. Significant (p<0.05)
variation exist within and between ecotypes using population coefficient of variation (ANOVA) bill height had
the highest coefficient of variation 79.52 while body length recorded the least variation. There are marked
differences in body morphology between sexes in all the ecotypes indicating significant sexual dimorphism.
Correlation between the traits were low to high. The inter specific variations in bill structure and body
morphology are indication of adaptation to the environment and influence of ecological condition
