SEM = pooled standard error of the mean for animal type effect; BW = body weight; DM = dry matter; NDF = neutral detergent fiber; GE = gross energy; DE = digestible energy; ME = metabolizable energy.

^a,b,c,dMeans in a row without a common superscript letter differ (P < 0.05).

AT = animal type; WT = water treatment.

ANG = Angora goats; BOE = Boer goats; SPA = Spanish goats; DOR = Dorper sheep; KAT = Katahdin sheep; STC = St. Croix sheep.

Mean values by breed × water treatment are presented in Tables S1–S3.
