Figure 2.

Rectal and facial temperatures in heat-stressed wether lambs supplemented with ractopamine or zilpaterol. Data are shown for rectal temperatures measured with digital thermometers (A) and for corneal (B), ear (C), and nose (D) temperatures measured with an infrared camera at distances of 1 and 2 m. Effects of experimental group (GRP), supplement, and the interaction (G*S) were evaluated and are noted where significant (P < 0.05). a,b,cMeans with different superscripts differ (P < 0.05).
