Abstract: An experiment was carried out during 86 days to evaluate the influence of yeast culture (Yea-Sacc1026) addition on live weight gain (LWG) of cattle on a diet of grass, poultry litter and wheat middlings. A completely randomized design was used to compare two treatments. with or without 10 g/day of yeast culture sprayed over the concentrate. Sixteen Brahman x Holstein yearlings, eight females and eight males, with an initial weight of 279 kg, which grazed on paddocks of Cynodon lemfuensis   were stalled during 3 h/day and offered 4 kg/day concentrate with equal amounts of poultry litter and wheat middlings. The animals were balanced between treatments according lo sex and weight. A multifactorial analysis of variance was carried out, with treatment and sex as sources of variation. On treatments with and without yeast culture, concentrate intakes were 2.82 and 2.79 kg DM/day (P>0.05) and LWGs were 0.78 and 0.59 kg/day (P=0.018). At present prices, the use of yeast resulted in a profit increase per animal of Bs. 10,845 during the trial. LWG was higher than results obtained in similar trials, possibly as a result of the relationship between yeast mechanisms of action and diet characteristics, and in these conditions its use is economically justified.
