The authors evaluated the performance of Muscovy duck (MD) and Common duck (CD) drakes reared under different techniques. A total of 356 birds (178 MD) and 178 CD) were used for the trial. All birds were reared from the first day of life to 28 days inside a windowless poultry house then one half MD and CD were transferred to open air pens (similarly to the France rearing system which assigns the Label Rouge). Results showed that the system which imposed the open air rearing system did not determine a reduction of growth speed in MD and in CD. Open air rearing system induced an increase of feed consumption in both species without significant differences in feed conversion.

Abstract
The authors evaluated the performance of Muscovy duck (MD) and Common duck (CD) drakes reared under different techniques. A total of 356 birds (178 MD) and 178 CD) were used for the trial. All birds were reared from the first day of life to 28 days inside a windowless poultry house then one half MD and CD were transferred to open air pens (similarly to the France rearing system which assigns the Label Rouge). Results showed that the system which imposed the open air rearing system did not determine a reduction of growth speed in MD and in CD. Open air rearing system induced an increase of feed consumption in both species without significant differences in feed conversion.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
