Does agricultural food provide a good alternative to a natural diet for body store deposition in geese?
Over the past decades most goose populations have become increasingly dependent on agricultural crops during wintering and migration periods. The suitability of agricultural crops to support all nutritional requirements of migratory geese for the deposition of body stores has been questioned; feedin...
