Comparison of Tifton 44 and Coastal Bermudagrasses as Pastures and as Harvested Forages

University of Georgia College of Agriculture, Coastal Plain Station, Tifton 31794

Abstract

Coastal bermudagrass and Tifton 44 bermudagrass (a new hybrid submitted for release in January, 1978) were compared as pasture and as pellets made from harvested dehydrated forage. Steers grazing Tifton 44 gained .80 kg/ day compared with .67 kg/day for steers grazing Coastal bermudagrass (P<.05). When the two bermudagrass varieties were harvested and fed as dehydrated pellets, animals fed Tifton 44 gained about 19% faster (P<.05) than animals fed Coastal and required 15.9% less (P<.05) feed per unit of gain. In a replicated digestion trial, the digestibilities of dry matter, crude fiber and nitrogen-free extract were greater (P<.05) for Tifton 44. The digestibility of the ether extract fraction was 4.7% greater (P<.05) for Coastal bermudagrass. Nitrogen retention values were greater (P<.05) for steers fed Tifton 44 bermudagrass.
