This study was carried out to evaluate the effects of replacing corn silage with ensiled tomato pomace on dry matter intake and apparent digestibility of diets. Eight close up dry Holstein cows were used in 2 ×2 Latin square design. The animals were fed control (0% tomato pomace silage) and experimental (10% corn silage replaced by tomato pomace silage) diets. The result showed that dry matter intake in experimental group was 9.77±0.44 kg/d, which was significantly higher than in control group (p<0.05). Dry matter digestibility in experimental and control group was 73.9% and 70.2%, respectively, but there was no difference between two groups (p>0.05). The substitution of tomato pomace silage in diet was associated with an increase of dry matter intake, dietary supplement of ensiled tomato pomace without any adverse effect on their health performance.
