A total of 250 one-day-old Ross 308 male chicks were used to investigate the effects of Fe-methionine (Fe-met) and iron sulfate (FeSO 4 .7H 2 O) on performance, mineral concentration, meat quality, and oxidative stability of breast. The feeding experiment was performed with five dietary groups including group I (basal diet [BD] + 80 mg/kg FeSO 4 ), group II (BD + 60 mg/kg FeSO 4 + 20 mg/kg Fe-met), group III (BD + 40 mg/kg FeSO 4 + 40 mg/kg Fe-met), group IV (BD + 20 mg/kg FeSO 4 + 60 mg/kg Fe-met), and group V (BD + 80 mg/kg Fe-met). The results showed that Fe and Cu content in the breast muscle increased by dietary supplementation of organic and inorganic iron from II to V groups. Dietary groups of II, IV, and V increased L* value and b* value of breast meat. Additionally, redness of breast meat enhanced linearly and quadratically by dietary supplementation of 80 mg/kg Fe as FeSO 4 . In addition, dietary supplementation Fe from II to V groups led to a significant increase in pHu at 24-h postmortem while it was negatively correlated with L* value of breast muscle. This study demonstrates that replacing FeSO 4 with Fe-Met could improve breast meat yield of broilers.Although 80 mg of Fe-Met improved the iron content of meat, it showed detrimental effects on the lipid oxidation of breast meat.

Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.005 Å; R factor = 0.072; wR factor = 0.174; data-to-parameter ratio = 19.9.In the crystal structure of the title triazole compound, C 14 H 9 ClN 4 O 2 S, molecules are connected into centrosymmetric dimers by pairs of N-HÁ Á ÁS hydrogen bonds. In addition, there are weak C-HÁ Á ÁN hydrogen bonds stabilizing the crystal structure. The dihedral angles between the triazole ring and the two benzene rings are 73.0 (4) and 72.9 (4) .
