The study was conducted using one hundred and fifty matured domestic pigeons to measure body linear parameters as well as external and internal egg quality characteristics in other to determine phenotypic relationships and predict body weight from body linear measurements. Data were collected on body weight, shank length, breast girth, body length, wing length, tail length and beak length at maturity. Two hundred eggs were collected and analyzed for both external and internal quality characteristics. The data obtained were analyzed using the correlation and regression procedure of SPSS Statistical software. The result obtained from this study body weight correlate positively with all other body linear parameters. However, the relationships between beak length and other body parameters except body weight were negative and mostly low. The strongest relationship in this study was between body weight and shank length. The coefficient of determination was highest for shank length (0.710), followed by wing length (0.680), breast girth (0.630) while tail length had the least coefficient of determination (0.360). It was suggested that the best equation for predicting body weight from linear body measurement could be: BW = 40.9+1.96BL-0.84WL+3.98BG+0.112SL. From the findings of this study, it was concluded that shank length is the most suitable body measurement that could be used for selection of domestic pigeon due to its strongest phenotypic correlation with body weight and other body parameters.
