Summary

A policy of introduction of forages in the crop rotation of the irrigated schemes has recently been suggested. Information on the nutritive value of such forages is important for any feed formulations for livestock. Using the nylon bag technique and a mathematical model, the degradability of two legume forages (Berseem and Clitoria) and two cereal forages (Abu 70 and Sorghum hybrid) is reported in this paper. At the different ruminal incubation time intervals and a range of ruminal outflow rates, the legume forages showed a higher degradability than the cereal forages in all forage components (DM, CP and CF). Berseem had the highest degradability and the sorghum hybrid had the lowest.
