Abstract

The experiment was carried out to study the effect of increasing levels of tomato pomace (TP), substituting hay, on performance of feedlot calves. Twenty crossbred calves with 161 kg of initial body weight allocated in pens in groups of five were used. The four treatments empregated were: A) Brachiaria decumbens hay (BRAD) 100% of rougaghe dry matter (DM); B) BRAD 73% + TP 27%; C) BRAD 46% + TP 54% and D) BRAD 19% + TP 81%. Four concentrates, composed by soybean meal, corn grain cracked and minerals, were used to maintain isocaloric and isoproteic diets. The average daily gain (ADG) was measured in 28 days intervals. The ADG (kg/day) was not affected by treatments (P>0.05): A) 0.88; B) 1.07; C) 1.04 and D) 1.21. It was possible to substitute up to 80% of hay DM with TP without negative effects on ADG.
