Abstract

Information regarding FORAGE QUALITY and its variation in different climatic zones and at various PHENOLOGICAL STAGES can help a range manager to determine daily animal requirement which in turn is essential in an evaluation of grazing capacity. In order to determine FORAGE QUALITY, five species of vegetation namely; Agropyron tauri, Agropyron trichophorum, Bromus tomentellus, Festuca ovina and Hordeum bulbosum were collected from 18 vegetation communities of 8 CLIMATE zones and at three PHENOLOGICAL STAGES of vegetative, flowering and seed ripening. Plant samples were analysed to determine N prcentage as well as ADF. Metabolizable Eenergy was assessed as a FORAGE QUALITY factor.Variance analysis was applied to data. Results indicated that METABOLIZABLE ENERGY is significantly affected by species, phenological stage as well as climatic zone.
