Description
This study compared the yield potential and inherent nutritive value and quality of tropical corn (Zea mays L.) with temperate corn and two forage sorghums [Sorghum bicolor (L.) Moench] for use in multiple cropping systems. Tropical corn showed high dry matter yield potential (19.3 Mg ha-1) compared with a selected temperate corn (14.7 Mg ha-1) or with an intermediate (8.5 Mg ha-1) or taller growing forage-type sorghum (10.3 Mg ha-1). Neutral detergent fiber concentration (g kg-1) was lower for temperate corn (330) than for tropical (548) corn which had a concentration similar to the intermediate (497) and forage-type sorghums (543). Dry matter intake was similar among silages (1.83 kg+100 kg-1 body weight) but apparent dry matter digestion was higher (P = 0.01) for temperate corn (64.0%) vs. tropical corn (59.8%). Tropical corn had similar digestion values to intermediate sorghum silage (61.4%) but lower than forage sorghum (64.5%).
