TI  - Effects of Graded Levels of Chromium Methionine on Performance, Carcass Traits, 
      Meat Quality, Fatty Acid Profiles of Fat, Tissue Chromium Concentrations, and 
      Antioxidant Status in Growing-Finishing Pigs.

AB  - A 97-day feeding trial was conducted to investigate the effects of dietary 
      chromium methionine (CrMet) on performance, carcass traits, meat quality, fatty 
      acid profiles of fat, tissue chromium concentrations, and antioxidant status in 
      growing-finishing pigs. A total of 180 crossbred pigs with a mean initial body 
      weight (BW) 30.18 +/- 0.28 kg were allotted to 5 treatments with 6 replicates per 
      treatment and 6 pigs per pen in a randomized complete block design based on BW 
      and sex. Treatments were added with 0 (control), 100, 200, 400, and 800 mug/kg 
      chromium as CrMet. Blood samples were obtained from the anterior vena cava on 
      days 97. Carcass characteristics, pork quality, and tissue chromium concentration 
      data were collected from one pig per pen. The results indicated that supplemental 
      CrMet did not significantly affect growth performance, carcass traits, or meat 
      amino acid profiles. Chromium at 100, 400, and 800 mug/kg decreased drip loss but 
      increased shear force (P < 0.05). Pigs fed 100 or 400 mug/kg had a higher 24-h pH 
      than the control (P < 0.05). While meat color, muscle moisture, crude protein, or 
      crude fat were not affected by CrMet. Supplemental 800 mug/kg chromium reduced 
      C18:0 levels in belly fat (P < 0.05), and chromium supplementation increased 
      cis-9, trans 11-conjugated linoleic acid levels linearly (P < 0.05). Dietary 
      CrMet supplementation increased serum, kidney, and muscle chromium contents 
      (P < 0.05) but did not affect liver chromium contents. Besides, tissue chromium 
      concentrations were increased linearly with increased chromium dosage (P < 0.05). 
      Chromium at 400 mug/kg increased serum glutathione peroxidase activities 
      (P < 0.05), and chromium at 800 mug/kg decreased serum total antioxidant capacity 
      levels (P < 0.05). Nevertheless, liver and kidney antioxidant status were not 
      significantly affected by CrMet. These results indicated that dietary 
      supplementation CrMet did not significantly influence growth and carcass traits, 
      but improved meat quality at the expense of tenderness. Therefore, the long-term 
      exposure to 800 mug/kg chromium affected fatty acid compositions and reduced serum 
      antioxidant capacity.
