  • Dr Ates’s research focuses on pasture and grazing management for improved animal production and product quality. His current research interest includes (1) Novel pasture and grazing systems, 2) Animal-pasture interactions, in particular intake, diet preference and behavior of grazing ruminants, 3) Evaluation of tannin-containing legumes for livestock grazing, 4) Management of self-reseeding annual legumes in permanent pastures and 5) Dual purpose and cover crop grazing.
