Growth dynamics of fourwing saltbush as affected by different grazing management systems.

Abstract

Changes in liveweight of sedentary and migratory herds of cattle in south Kordofan Province, Sudan, were determined monthly. Feces of these animals were analyzed for N and ADF during the same period. Both the sedentary and the migratory herds gained liveweights during periods August to September and November to February and lost liveweight during October and from March to July. Changes in liveweights were more highly related to fecal ADF concentrations (r = -0.60, P & 0.002) than to fecal N concentrations (r = -0.085, P & 0.305).
