The study was undertaken to determine biometric characterization of locally adapted Muscovy ducks in Nasarawa South Agricultural Zone. Three hundred matured Muscovy ducks were randomly selected from three randomly selected LGAs in the Nasarawa south Agricultural zone and used for the experiment. Body weight and body linear measurements as well egg qualities characteristics were determined across lafia doma and Awe Local Government Area of Nasarawa South. The data collected were analysed using one way analysis of variance (ANOVA) of the SPSS statistical package version 21. The results obtained indicated that, birds from Awe (location 3) had significantly (P<0.05) higher body weight (2.22±0.07 kg), wing length (40.74±0.73cm), tail length (18.93±0.26cm), egg weight (66.79±0.64g), albumen length (10.20±0.17mm) and albumen width (6.60±0.16mm) compared to those from locations 1 and 2 (Lafia and Doma). However, birds from Lafia (location 1) had significantly (P<0.05) higher chest circumference (14.76±0.26cm) and comb length (2.16±0.46cm) compared to birds from Doma and Awe (locations 2 and 3). Similarly, birds from locations 1 and 2 (Lafia and Doma) had significantly (P<0.05) higher shank length (5.91±0.16cm and 5.93±0.17cm, respectively) toe web (5.97±0.14cm and 5.92±0.14cm, respectively) and egg length (6.13±0.02mm and 6.07±0.02mm, respectively) compared to birds from location 3 (Awe). From the finding of this research, it was concluded that location have effect on Muscovy duck as such selection of these birds should be location based and subsequently be cross bred to utilise heterosis.
