Determination of Nutritional Values of Some Rangeland Plants Species Grazed by Camels, Through Chemical Method and Nylon Bags Technique in Gadarif and North Kordofan States, Sudan

Abstract

This study has been carried to assess nutritional potential of some rangeland plants species (herbs, forbs, shrubs and trees) are grazed by camels in Gadarif and North Kordofan States, Sudan. The rangeland samples were chemically and biologically analyzed to evaluate their nutritional potential for camels through proximate analysis and in situ method. The study carried depended on randomized complete design with three fistulated camels in three replications and the data obtained were analyzed using descriptive statistics. The results obtained revealed that, the rangeland plants species varied in nutritional content and characteristics of degradation. The content of crude protein )CP) was highest in Corchorus trilocularis (Mulukhia) (12.0%), however, the Grewia tenax (Gudaim) showed least value (6.7%). Boscia senegalensis (Mukheit) showed highest CP potential degradability , while the least was shown in Guiera senegalensis (Gubeish). The results revealed that, the effective degradability differed in plants species and decreased with increasing rates of outflow from the rumen. It is concluded that camels have significant feeds rumen degradation, therefore, we recommended to the use of information obtained to adopt modern ruminants nutrition systems in camels nutrition for efficient feeding and production.
