In order to evaluate tomato pomace as an alternative source of nutrient for growing meat rabbits, with purpose of reducing feed costs, it was carried out a research to determine the effects of increasing levels of tomato pomace in their diet. The experimental treatments consisted of including four different levels of tomato pomace (0%, 10%, 20% and 30% of a normal diet). Sixty four young female and male rabbits were randomly allotted in groups of 16 (8 males and 8 females) for each treatment, being located 2 in each cage. Live weight changes and daily intake were measured. Average daily intake was significantly affected by diets with 30% of tomato pomace, decreasing 21% in relation to the control group. A tendency to larger daily gains was observed at 10% level of substitution, and at higher levels, they were significantly affected. From these results it is possible to conclude that is feasible to include no more than 20% of tomato pomace in rabbit diets. Higher levels produce a negative effect in daily gains and intake, specially on males. Similar effects are not observed in females
