Since meat quality is actually of great importance in Europe and open air rearing is imposed by several trademarks of quality, the authors evaluated the performance of Muscovy and common duck bred with different techniques (rearing period: whole inside a poultry house and rearing period with finisher at open air). Results showed that systems which impose the finisher period at open air determined a slightly reduction of growth speed in Muscovy ducks while determined an increase of live weight in common ducks. Open air breeding during the finisher period induced a little increase of feed consumption in both species but only in Muscovy duck conversion efficiency was slightly worsened.

Abstract
Since meat quality is actually of great importance in Europe and open air rearing is imposed by several trademarks of quality, the authors evaluated the performance of Muscovy and common duck bred with different techniques (rearing period: whole inside a poultry house and rearing period with finisher at open air). Results showed that systems which impose the finisher period at open air determined a slightly reduction of growth speed in Muscovy ducks while determined an increase of live weight in common ducks. Open air breeding during the finisher period induced a little increase of feed consumption in both species but only in Muscovy duck conversion efficiency was slightly worsened.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
