SEM = pooled standard error of the mean for the water treatment effect; tHb = total hemoglobin.
a,b,cMeans within grouping without a common superscript letter differ (P < 0.05).
ANG = Angora goats; BOE = Boer goats; SPA = Spanish goats; DOR = Dorper sheep; KAT = Katahdin sheep; STC = St. Croix sheep.
FR = fresh water; 100-BR = brackish water (BR); 100-SL = NaCl added to FR for a similar total dissolved solids (TDS) level as 100-BR; 150-BR = 100-BR plus addition of approximately 50% of 100-BR TDS; 150-SL = NaCl added to FR for a similar TDS level as 150-BR; 150-BR/SL = a similar TDS level as 150-BR and 150-SL by addition to 100-BR of a 1:1 mixture of BR minerals and NaCl.
