Resumo: 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. KEY-WORDS: Byproducts; hay; ruminant; nutrition.

Este trabalho foi conduzido para avaliar os efeitos da inclusão de níveis crescentes de polpa úmida de tomate (PUT), em substituição ao feno de braquiaria decumbens (Brachiaria decumbens Staf), sobre o desempenho de bovinos confinados. Foram utilizados vinte bovinos mestiços E x Z com 12 meses de idade e peso inicial de 161 kg, alojados em grupos de cinco em baias de 60 m2. Os quatro tratamentos empregados foram: A) Feno de braquiaria decumbens (FHRAQ) 100% da matéria seca proveniente da forragem (MSF); B) FBRAQ 73% + PUT 27% da MSF; C) FBRAQ 46% + 54% PUT da MSF; D) FBRAQ 19% + 81% PUT da MSF. Quatro concentrados compostos por farelo de soja, grão de milho triturado e minerais foram usados para manter as rações isocalóricas e isoprotéicas. O ganho de peso médio diário (GMD) foi avaliado em intervalos de 28 dias. Não houve efeito dos tratamentos sobre o GMD (kg/dia): A) 0,88; B) 1,07; C) 1,04 e D) 1,21. Dessa forma, foi possível substituir até 80% da MS do FBRAQ com PUT sem efeitos negativos sobre o GMD.
