Body composition of Angus and Nellore bulls. The lines represent the allometric equations of the quantity of compound present in the empty body as a function of the EBW. a) Dashed line represents overall protein equation and long dashed line represents overall ash equation; b) solid line represents Angus fat equation; dotted line represents Nellore fat equation; Circles are for protein, triangles are for fat and squares are for ash. Filled symbols are for Angus and nonfilled symbols are for Nellore.

a) Relationship between metabolizable energy intake (MEI) and logarithm of heat production (HP; Lofgreen and Garret, 1968). Angus equation is log HP=− xMEI and Nelore equation is log HP=− xMEI (P<0.001; RMSE=0.019). b) Relationship between MEI and HP (Ferrell and Jenkins, 1998). Angus equation is HP=0.417xexp(0.695xMEI) (P<0.001; RMSE=0.0309) and Nellore equation is HP =0.334xexp(0.883xMEI) (P<0.001; RMSE=0.0471). Solid lines and circles are data from Angus and dashed line and triangles are data from Nellore. HP and MEI are in MJ/kg EBW0.75·d−1.
