Dry matter, protein, energy and fibre intake by dairy heifers grazing a Rhodes grass (, Artus, F. ; Champannet, F., 1989. It is a plant that can grow in various conditions and environments, including savannas. Dichrostachys cinerea is widespread throughout Africa and is often found in the savannas. It flowers in the autumn and winter months, producing small greenish yellow blooms. The savanna is most popular to herbivores, which can dine on the diverse grasses found there during the wet season. Its creeping habit provides good soil stabilisation and, in Australia, it is commonly used for the revegetation of mine-disturbed soils (Harwood et al., 1999). Or it can be grown as groundcover to protect the soil from erosion. Of course, where you have lots of herbivores, there must be predators. Carbon dating has found some specimens that are more than 2,000 years old. Each spikelet in the raceme is a few millimeters long and contains one or two fertile florets and up to four sterile florets. In Kenya, dairy heifers grazing Rhodes grass had an average daily gain of 581 g/day during a one year experiment with a stocking rate of 2 livestock unit/ha, but the pattern of gain ranged between 200 and 1100 g/d according to the period of the year.
