ABSTRACT.- Context:Demand for dairy products is expected to continue driving intensification in dairy systems. Little is known about the productive and economic performance and risk of intensification strategies either within grazing systems or confinement dairy systems in Argentina.cu Objective:This study investigated four strategies to double milk production for the average grazing dairy system of Argentina (BASE), using either grazing or confinement systems. Physical and economic performance and risk associated with each alternative was explored using a modelling approach.

The objective of this study was to investigate the feeding behaviour impact due to walking in dairy cowswalking 5 km between the milking parlour and the pasture plot in a grazing system, separating the effect of walking itself from the fasting period associated to walking.
