摘要： The dynamic state of nutrient contents of Vetiver grass was studied. Grass samples were collected and analyzed in different seasons, types of soil condition, growth stages and mowing times. The results showed that nutrient contents of Vetiver grass were correlated highly to seasons, growth stage and types of soil condition. Vetiver grass passing through winter showed lower nutritive value than those growing in other seasons. Vetiver grass growing in sand showed lower nutritive value than those growing in soil. Nutrient contents reached the highest level in the tillering stage and then decreased in the jointing stage. Vetiver grass that grew in pig farm wastes showed higher contents of crude protein, carotene and lutein, relatively lower contents of ash, Ca, Fe, Cu Mn and Zn, and contained acceptable levels of heavy metal (Pb, As and Cd), which indicated Vetiver grass which grew in pig farm waste was still a promising feed resource for ruminants.
