Forage value of vegetative leaf and stem biomass fractions of selected grasses indigenous to African rangelands

Context Rangeland grasses native to Africa constitute the main diet for free-ranging livestock and wild herbivores. Leaf:stem ratio is a key characteristic used assessing quality of forages. However, studies determine allocation biomass leaves stems as well chemical components nutritive value, especially in African rangelands, are rare. Aim This study was conducted establish mineral leaf stem fractions three grasses, Eragrostis superba, Enteropogon macrostachyus Cenchrus ciliaris, all indigenous rangelands. Methods Plant height, plant densities, tiller densities yields were estimated at elongation stage, before inflorescence. Chemical determined from harvested vegetative phase grass species. Dry matter, ash content, organic crude protein, neutral detergent fibre, acid lignin, calcium, phosphorus potassium contents determined. Key results displayed significantly greater height than other two Leaf varied (P < 0.05) among grasses. E. superba double that C. ciliaris. Crude protein matter net energy lactation highest biomass, Ca content. Conclusions demonstrated potential forage species ruminant animal production Implications warrants promotion pasture establishment programs its environments.
