During 90 days 243 finishing feedlot animals from two genetic groups, were weighed every 28 days in a randomized experimental procedure in a 2 x 3 factorial arrangement, with two breeds - Nelore (Nel) and Canchim (Can) - and three treatments: water (A), cane stillage + magnesium oxide (V) and cane stillage + magnesium oxide + sodium bicarbonate (V + B). The diet for all treatments was composed of 70% of corn silage and 30% of chopped sugar cane ad libitum plus 1 kg of ground corn and 1,5 kg of soluble yeast per animal. Results showed higher weight gain (P < 0,01) of the Can group relation to those of Nel, having respectively 1,35 and 1,22 kg/head/day. Both Can and Nel groups showed higher weight gain (P <.01) when fed with V + B, with 1,44 and 1,32 kg/head/day respectively when comparing to the other diets: Can (A) = 1,30; Can (V) = 1,31; Nel (A) = 1,16 and Nel (V) = 1,20 kg/head/day. The diet using V + B has also showed a tendency (.05 <P <.10) of better food conversion thus showing positive effect of cane stillage when associated to the neutralizing compounds of the ruminal pH.
