Table 3 Final body weight (FBW), liver weight, heart weight, glutathione peroxidase activity (GPX, U/ml), total antioxidant status (TAS, mmol/l), mg selenium/kg leg muscle, thiobarbituric acid reactive substances (TBA) mg/kg leg muscle and front face fluorescence spectrometry (FFF) and thigh muscle fatty acid composition (g/100 g fatty acid) for broilers fed diets based on wheat with different fat source; rapeseed oil (RO) or rapeseed oil plus linseed oil (LO), and with different selenium concentration: 0.50 mg Se/kg or 0.84 mg Se/kg diet.

From: Effect of dietary selenium and omega-3 fatty acids on muscle composition and quality in broilers
