Abstract :

Yield and the quality of the rangeland depend on the botanical composition. The purpose of this study isto investigate the nutrient content of the plants available in a native rangeland on the family basis withrespect to the nutritional requirements of the livestock grazing on that rangeland. The results of thestudy showed that the legumes found on the rangeland were rich in crude protein (CP) content whileother species belonging the other families were sufficient with the exception of grasses, which wasinsufficient. With respect to the quality factor, it was found that legumes and other families were “firstclass” in terms of their acid detergent fiber content with the exception of grasses, which was classifiedas “second class”. Moreover, it was found that legumes and other families were “first class” in terms oftheir neutral detergent fiber content with the exception of grasses, which was classified as “4th grade”.The relative feed value of the species belonging to legumes, grasses and other families were found as145.6, 90.4 and 125.9, respectively. Legumes and species belonging to other families were foundsufficient while grass species were found insufficient in terms of their ability to meet the metabolicenergy (ME) requirements of the livestock grazing on the rangeland. There are marked differencesbetween plant families found in rangelands in terms of their abilities to meet nutrient requirements ofanimals. As a result, the presence of legumes and the other families in adequate amounts is vital formeeting the CP, digestible dry matter and ME requirements of animals.
