Resumen
Equine production in Buenos Aires (Argentina) is 512847 heads. The equine production management is an important factor for the minimization of environmental effects. This management includes the implementation of good practices. The aim of this paper is to characterize the equine production paddocks in Buenos Aires in terms of their management, and to evaluate the possible environmental impact they may generate. Sixteen paddocks have been characterized according to the sources of water supply, quantity and depth of the wells, breed, productive system, type and management of beds, type of feed, feeding practices, supplementation, other ration components and management. These are the first studies on environmental effects of equine production in Argentine.
