AB  - Twenty Hampshire lambs (31 +/- 4 kg BW) in individual metabolism cages were used in 
      a 10-treatment by 2-period ( = 4) trial to evaluate the interaction between 
      protein supplementation and sulfate water on intake and metabolic responses when 
      lambs were fed low-quality grass hay (; 6.4% CP, 79.5% NDF). The treatment 
      structure was a 2 x 5 factorial: 2 water qualities (WQ; low-sulfate [LS] and 
      high-sulfate [HS]; 442 and 8,358 mg/kg total dissolved solids, respectively) and 
      5 soybean meal levels (SBM; 0%, 0.25%, 0.50%, 0.75%, and 1.00% BW/d). After 15 d 
      of adaptation, periods consisted of 5 d for determination of forage and water 
      intake, nitrogen balance, and digestion measurements (d 16 to 20) and 1 d for 
      blood sampling and determination of ruminal hydrogen sulfide (HS) concentration 
      (d 21). Supplemental SBM x WQ interactions were significant for forage OM intake 
      ( = 0.04) and total OM intake ( = 0.04), whereas a tendency was observed for 
      total tract digestible OM intake ( = 0.07). Intake values of LS lambs were higher 
      than those of HS lambs ( < 0.05) in only the first and second levels of SBM. 
      Water intake increased linearly ( < 0.01) with SBM level but was not affected by 
      WQ ( = 0.39). Water quality and SBM supplementation affected total tract OM 
      digestibility (TTOMD; < 0.01); LS lambs had lower TTOMD than HS lambs ( < 0.01). 
      Plasma urea N increased linearly in response to SBM ( < 0.01) but was not 
      affected by WQ ( = 0.11). Nitrogen balance was not affected by SBM x WQ 
      interaction ( > 0.12), except for N utilization (N retained/N intake ratio; < 
      0.01). Regardless of WQ, N intake ( > 0.01), N urine ( > 0.01), and N balance 
      increased linearly ( > 0.01) with SBM level. Water quality adversely affected N 
      intake and N balance, although at the highest level of SBM no differences in N 
      balance were observed between LS and HS lambs ( = 0.85). No changes due to WQ 
      were observed for either urea reabsorbed by kidneys ( = 0.63) or glomerular 
      filtration rate ( = 0.30), but renal function was affected by SBM level ( < 
      0.01). There was a supplemental SBM x WQ interaction for ruminal HS concentration 
      ( < 0.01) due mainly to a greater concentration from 0.25% BW SBM in HS than in 
      LS lambs. In conclusion, these results confirmed the existence of an interaction 
      between sulfate water and supplemental protein, which alters intake and metabolic 
      responses when lambs are fed low-quality grass hay.
