In the town of Tumbaco-Pichincha, a supplementation system using yeast and “Roughage Mate” “3 Nitro-20” was evaluated in calves Holstein-Friesian, weighing, in average, 90 kg 3 to 6 months old. The objective of this study was to evaluate the effect of food additives and yeast on growth and body condition of the animals. We used a completely randomized design with four observations and one experimental unit consisting on a calf. The variables evaluated were: weight gain, body condition, increased and wither height. The results indicate that the best treatment was that of additive March 20 Nitro, with which calves reached a weight gain of 0.80 kg / calf / day, an increase of girthplace 0.24 cm / calf / day and wither height of 11 cm / calf / day; while the best body condition score was 2.75.
