Hematology, blood chemistry and selenium values of captive pronghorn antelope, white-tailed deer and American bison.

Pronghorn were observed to have a significantly higher whole blood selenium concentration than either the white-tailed deer or bison. Pronghorn colloid values were significantly less than those of the bison, and approached statistical significance for the white-tailed deer. Differential white blood cell counts for the white-tailed deer were markedly different from those of the pronghorn and bison. The American bison had significantly higher cortisol values and lower T3 values than either the white-tailed deer or pronghorn.
