Effects of Varying Levels of Dietary DL-Methionine Supplementation on Breast Meat Quality of Male and Female Broilers

This study evaluated the effects of feeding varying levels dietary DL-methionine (MET) supplementation on breast meat (BM) quality broilers different sex. The 1-day-old, sexed chicks (Ross 708, 1552) were randomly allocated into four groups (each with 4 replicates) and raised diets supplemented 0, 0.5, 1, or 2 g MET/kg feed to a common weight (2.72 kg). Color, pH, drip loss (DL), water-holding capacity, moisture uptake, cooking yield (CY), texture, total antioxidant capacity (TAC), lipid oxidation (LO) determined using BM samples harvested 24 h postmortem. male had higher redness, TAC, firmness, toughness but lower yellowness (p < 0.01) than female BM. In both sexes, birds fed 0.5 g/kg MET DL those 1 MET. For storage up 3 days, suppressed LO in cooked suppression increased as increased. CY for 0.01; 79.04 78.60%, respectively) 0 (66.18 68.03%, respectively). These results suggest that at can improve oxidative stability, muscle functionality, CY.
