The Effect of Supplementation with Fresh Browse of Ziziphus mauritiana or Combretum aculeatum on Feed Intake, Nitrogen Utilization and Growth of Grazing Range Sheep

摘要: The influence of 0, 60 or 120 min access to a grove either Ziziphus mauritiana (Ziziphus) Combretum aculeatum (Combretum) on forage intake and the digestibility, growth excretion nutrients was determined using 40 Oudah rams grazing for 7 h/day poor-quality dry season pasture in Sahel. effects browse species browsing duration (0, 30, min) ruminal ammonia content were also evaluated 8 mature fistulated rams. increased both total digestible organic matter intakes per (kg live weight)0.75 without decreasing herbage intake, whereas reduced by 6.3% 4.2%, respectively. digestibility diet decreased (p < 0.05) with groves. Despite provision more nitrogen (N) than control diet, NH3-N 24 h after commenced. weight gain sheep may indicate deleterious compounds Ziziphus. appears have potential increase production low-input crop/livestock systems.
