Abstract:
The purpose of this study was to predict 20 weeks body weight and adult body weight of ‘Nageswari’ duck of Assam from body measurements viz., shank length, body circumference and keel length by developing different linear and multiple regression equations. A total of 128 ducks comprising 22 male and 106 female reared traditionally were used for the study. Highest R² values of 97.89 and 98.59 percent were observed in the equation incorporating all the three body measurements to predict 20 week and adult body weight respectively. Thus, multiple regression equations that included a combination of these three linear body measurements are more suitable for predicting body weight of Nageswari duck populations.
