Comparación de métodos basados en los requerimientos nutricionales y disponibilidad de biomasa para estimar la capacidad de carga para venado cola blanca

Due to the importance of the estimation of carrying capacity (K animals/ha) in white tailed deer, the objectives of this study were: 1) To compare the estimation of K with five methods, three of them based on nutrient availability (dry matter (DM), digestible energy (DE) and nitrogen (N)), one based...
