Experimental design and rectal body temperature recording and blood sampling schedule for beef calves that were housed on day (d) 0, and either (i) weaned (W: n = 8), or (ii) not weaned (controls) (C: n = 8). Rectal body temperatures were recorded and blood samples were collected on d −4, 0, 1, 2, 3, and 7 relative to housing on d 0. On d 0, samples were obtained prior to housing.
