A trial was conducted to evaluate forage production and quality of fíve comercial com hybrids (Zea mays) and three sorghum hybrids (Sorghum bicolor). The experimental design was randomized blocks with three replicates. The five com hybrids were: Pioneer 3072 (P 3072), Agroceres 211 (AG 211), Cargill 525 (C 525), Pioneer 3232 (P 3232) and Agroceres 213 (AG 213) and the three sorghum hybrids were: Agroceres 2004 E, 2002 and 2005 E (AG 2004 E, AG 2002 and AG 2005 E, respectively). Plant population was about 50.000 and 160,000 plants/ha for com and sorghum, respectively. The crops were havested at a height of 15cm of soil surface, at grain powdering stage. After the harvested, the forage were ensiled in glass recipients, wich were conserved in a higher silum. The dry matter production of the P 3072 was higher than AG 213 and the three sorghum hybrids. Although all mean value results were adequate for silage conservation and quality, there was only significant difference for pH. The digestibility estimatives show a good quality potential for all hybrids, especially P 3072 and P 3232.
