This study was conducted to investigate the relationship of body weight to external body measurements such as body length, thoracic girth, abdominal girth, tibiotarsal, tarsometatarsal, wing length, and height from ground to the top of the back in adult, fighting cocks and to formulate possible equations to determine body weight. A total of 500 apparently healthy adult fighting cocks with age grouped into <12 mos and > 12 mos of different blood lines were used in this study. Results of correlation analysis showed a weak linear relationship between body weight and external body measurements. Simple regression analysis to identify a formula with a single best determinant of weight was not achieved. Multiple regression equations revealed that the combination of body length, abdominal girth, tibiotarsal length, and height were found to be the best predictor of weight among the parameters studied. However, a very low R2 value at 29% hinders its application on actual practice. Thus, further studies are recommended to identify the unaccounted factors that would give the best estimation of weight.
