Hay harvested at a later stage of maturity has a low protein content and a high fibre content, particularly in the stems, and it should be supplemented when fed to ruminants with nutritional requirements higher than those necessary for maintenance. These imposing trees are most commonly found in the hot and dry savannas of sub-Saharan Africa. Department of Primary Industries and Fisheries of Queensland, Land Protection (Invasive Plants and Animals), Biosecurity Queensland. The supplement increased total feed intake, doubled the growth rate, and improved the feed conversion ratio and the lean+fat:bone ratio (Mtenga et al., 1990). And one of the plants that helps give it that distinctive appearance is Rhodes grass. Grassl., 42: 112-119, Jones, R. J., 1981.
