Plasma hormone and substrate concentrations in control and pST-treated pigs at the beginning of the insulin clamp

	Saline	pST
PUN, mg/dl	12.2 ± 0.5	8.0 ± 0.4§
IGF-1, ng/ml	126.6 ± 29.2	290.1 ± 32.6§
pST, ng/ml	4.6 ± 2.8	119.6 ± 49.1§

Values are means ± SE; n = 11–13/treatment group. PUN, plasma urea nitrogen; IGF-I, insulin-like growth factor I; pST, porcine somatotropin.

^§P < 0.001 vs. saline-treated pigs. Significance determined by t-test analysis.
