AB  - OBJECTIVE: This study was conducted to evaluate the effects of concentrate level 
      and chromium-methionine (Cr-Met) supplementation on the growth performance, 
      carcass characteristics, meat quality, and fatty acid composition of Tan lambs. 
      METHODS: Sixty male Tan lambs (21+/-1.23 kg body weight) fed a finishing diet 
      (concentrate-to-forage ratio: 35:65 [LC group] or 55:45 [HC group]) with daily 
      Cr-Met supplementation (0, 0.75, or 1.50 g) were used in a completely randomized 
      design with a 2x3 factorial arrangement of treatments. RESULTS: Lambs from the HC 
      group had higher average daily gain, dry matter (DM) digestibility, dressing 
      percentages, leg proportions, intramuscular fat (IMF) contents, and saturated 
      fatty acid levels, but lower feed conversion ratios, globulin (GLB) and total 
      protein (TP) concentrations, shear force, and monounsaturated fatty acid (MUFA) 
      levels (all p<0.05). Cr-Met supplementation increased the DM digestibility, GLB 
      and TP concentrations, rack and loin percentages, and cooking loss, but decreased 
      the IMF contents and leg proportions (all p<0.05). Cr-Met supplementation at 0.75 
      g/d increased the conjugated linoleic acid (CLA) content in both the HC and LC 
      groups (p<0.01). Significant interactions between the concentrate level and 
      Cr-Met dosage were observed for MUFA (p<0.01) and polyunsaturated fatty acid 
      (PUFA) (p<0.01) levels. Meat from the lambs fed an unsupplemented LC diet 
      presented the highest PUFA and MUFA levels (p<0.01). However, the MUFA and PUFA 
      levels decreased significantly with increasing Cr-Met supplementation levels in 
      the LC group (p<0.01), whereas the opposite trend was seen in the HC group. 
      CONCLUSION: The HC diet improved the growth performance of Tan lambs, increased 
      their profitability by increasing leg and rack joint proportions, and improved 
      meat quality by promoting an IMF content that was more visibly acceptable to 
      consumers. Cr-Met supplementation at 0.75 g/d in a HC diet was the best choice 
      and may be economically beneficial.
