How Canadian farmers are extending the grazing season-A research success story

摘要：

In the Aspen Parkland of western Canada,feeding and managing the beef cow through the winter accounts for 60-65％ of the total cost of production in a cow‐calf operation ( McCartney et al 2004).Generally,200 winter feeding days ( late October to mid May) are required in the Aspen Parkland of western Canada..A series of research and extension activities were developed to evaluate the economics and sustainability of alternative year round grazing systems as a means of lowering the costs of beef production in western Canada.
