Influence of Housing System on Selected Quality Characteristics of Duck Meat. Chapter 2. Muscovy duck. The objective of this study was to determine the effect of housing system on the selected quality characteristic of breast muscles of Muscovy (MR71) ducks. The ducks were divided into four experimental groups according to their sex and housing system: intensive system (IS) and outdoor system (OS). Analysis was performed for a total of 48 breast muscle (12 in each experimental group: 2 x gender; 2 x rearing system). For test samples of meat there were determined: chemical composition, physicochemical properties and the sensory attributes of the breast muscles.There was no effect of housing system on the proximate composition of breast muscles of both MR71 ducks. Rearing system of ducks MR71 had significant (P<0.05) effect on cooking loss. The principal component analysis (PCA) showed, that meat of MR71 ducks from free range system is better perceived by the consumers than the meat of MR71 ducks from the intensive system, mainly for its greater tenderness and flavor.
