Agronomic importance clover Improvement of pasture quality Ryegrass 10-20%crude protein Legumes 15-25%CP It is for this reason that legumes are important food stuffs for both humans and animals (about 60%crude protein). Ryegrass is okay for metabolic maintenance(维持代谢)but protein conc. too low for efficiently fattening animals ■RAGE (育肥家畜)· Copyright reseved by Long College of animal science,Northwest Agriculture Forestry University 西北农林科技大学动物科技学院草业科学系 __________________________________________________________________ College of animal science, Northwest Agriculture & Forestry University  西北农林科技大学动物科技学院草业科学系 Copyright reseved by Long Mingxiu Agronomic importance ­ clover • Improvement of pasture quality –  Ryegrass 10 – 20% crude protein  –  Legumes 15 – 25% CP • It is for this reason that legumes are  important food stuffs for both humans and animals (about 60% crude protein). • Ryegrass is okay for metabolic  maintenance(维持代谢) but protein conc.  too low for efficiently fattening animals  （育肥家畜）
