Abstract

The byproduct of tomato processing was collected at the Etii Industry of Araçatuba, State of São Paulo, Brazil, and it has mainly seeds and skin. The tomato pomace presents the following composition (dry matter basis): DM 25.8%; CP 21.3%; CF 43.9%; EE 14.3%; MM 3.4%, NFE 17.1% and GE 5.23 kcal/g. This trial to evaluate the potencial of tomato pomace as cattle feed was conducted at Estação Experimental de Zootecnia de Andradina, State of São Paulo, Brazil. The experimental design was the latin square, with 4 Nelore steers, 36 months old and average weight of 319 kg. The rations were constituted of guinea grass hay (Panicum maximum, Jacq.) and 0%, 25%, 50% and 75% of tomato pomace (dry matter basis). There was no difference m dry matter intake. The digestibility coefficient of the DM and CF decreased linearly with the increase of tomato pomace in the ration. It was observed a quadratic effect (P < 0.05) m the digestibility coefficient of the CP with the addition of pomace. It was observed also a linear decrease in the TDN percentage (P < 0.05), with the increase in the percentage of pomace. The values of DP, TDN e DE for the pomace, estimated through the regressions equations were, respectively, 11.0%, 46.5% and 1.74 kcal/g.
