Abstract: Forage biomass is generally the most important resource for animal production in grass ecosystems
that is rapidly being depleted due to heavy grazing over vast areas of rangelands. So a comprehensive study
was conducted to determine the comparative nutrient value of available forage resources during various
seasons and the ability of these resources to meet the animal feeding requirements for optimum livestock
production. In the following study, ten native and exotic grass species were evaluated to find out the different
nutritional characteristics viz. moisture, ash, protein and crude fiber on percent basis in the field area of
department of Forestry, Range Management & Wildlife, UAF. Mean maximum moisture (%) was gained by P.
purpureum (79.42%) while minimum moisture percentage recorded in F. arundinacea (20.86%), Maximum and
minimum ash (%) was gained by C. ciliarus (10.62) and L. codensatus (4.39%) respectively. High crude protein
(%) was recorded in B. pertursa (9.70%) and low was reported in L. codensatus (3.05%). Mean maximum and
minimum crude fiber (%) was gained by B. pertursa (29.83) and C. gayana (0.56). Results show that B. pertursa
can be a useful adition for the maintenanace and enhancing the livestock productivity because it has high crude
protein and fiber percentage (%).

land management in non-agricultural marginal areas, hence, dependence on livestock is relatively high,
whereas, on rangeland livestock grazing signifies the most particularly for rural subsistence [5]. To match the
suitable land use [1]. Rangelands support 30 million herds maintenance requirements of livestock, there is a need of

often favored crops over livestock production, resulting present feed resources provide 40% CP and 75% TDN to

production potentials. Good pastures are being converted under nourishment, low productivity and predisposes the
into cropland leaving increasingly poorer lands for livestock to parasitism, epidemics and breeding problems.
