The purpose is to assess average daily gain of Brahman cross with frame sizetype(M andL) anddifferentbodyweights(350 kg) and theinteractionbetween theframe sizeanda differentbodyweights.The materialsused for this research were 3052 head SteerBrahmanCrosscattle with initial body weights250 kg-380 kg. This research was using study casus. data obtained was secondary data. The obtained data was analyzed using Completely Random Design (CRD) inbalanced factorial.The result showed that frame size has significant effect (P350 group were 1.329±0.366; 1.22±0.348; and 1.13±0.357 kg. The interaction between frame size and initial body weight give significant effect on Brahman cross steer daily gain. The gain of 350kg of initial body weight group with L frame size is 1.21 kg/day and M frame size is 0.93 kg/day. Key word : Average Daily Gain, Brahman cross, Frame size, Initial Body Weight
