Popis:	This study evaluated the effects of housing system (cage versus pen), sex and line cross (EMY1 and EMY2) on meat quality in meat-type chickens. Chickens (n = 640) from each line cross (males: females = 1:1) were housed in batteries from d 1 to 28. Then, half of them were transferred to indoor floor pens, and the others were raised in single cages. Meat quality traits of breast fillets were measured at 91 d of age. Percent lipid and histidine were higher, whereas % total protein and myofibre density (MDS) were lower in caged than penned chickens. Cross EMY1 had higher MDS, but lower lipid % and myofibre diameters (MDM) than EMY2 (p
