BIO-PREDICTION OF LIVE BODY WEIGHT USING MORPHOMETRIC TRAITS IN YORUBA ECOTYPE MALE CHICKENS
Abstract
The accurate prediction of live body weight using morphometric measurements has become an essential tool in poultry breeding, management, and production, especially in indigenous chicken populations where resources for advanced weighing facilities are limited. A total of
250 sexually mature male Yoruba ecotype chickens were used for the study. The data collected on body weight and linear body measurements regression analysis to predict the live body weight and Pearson correlation to determine the phenotypic correlation among the traits. Results revealed significant (p>0.05) correlations between body weight and several morphometric measurements; Wing length (0.686), Wing spine (0.866) and breast girth (0.938). The least correlation co-efficient (-0.260) is between shank length and wing spine. The study shows that when single variables were included shank length gives the actual bodyweight and when two variables were used wing length and wing spine gives actual bodyweight. This implies that live bodyweight of Yoruba ecotype can be predicted by both simple and multiple regression
