Intake and digestibility of leaves, Acacia macracantha (Am) and A. tamarindifolia (At), in rations mixed with ammoniated rice straw (R) and maize hominy (C), was evaluated for growing goats. 8 goats (20.5 kg liveweight) were used in the experiment. A complete randomized experimental design with a factorial (2×2) arrangement was conducted. The factors were: 1. Am and At; 2. Two different inclusion levels: low (18.75%) (L) and high (37.5%) (H). The intake of Am was higher (803 g DM/day) compared with At (638 g DM/day). Intake at different inclusion levels did not differ between species (H=685 and L=765 g/goat/day, P=0.247). The digestibility of the two Acacia species differed: DM, Am=80.02 and At=74.62%; NDF, Am=80.33 and At= 74.79%; hemicellulose, Am=94.35 and At= 88.50%. It was concluded that intake and digestibility of Am was higher than of At.
