Figure 1. Porcine growth characteristics during 1–27 days of treatment with a beta-adrenergic agonist (grey bars; BA) or recombinant growth hormone (black bars; GH), compared to a control cohort (white bars; C).

Changes in carcass weight (A), Semitendinosus (ST) muscle weight (B), Vastus Lateralis (VLAT) muscle weight (C) and liver weight (D) were measured. Average daily feed intake (E) and back fat depth (F) were measured following 27 days of treatment with beta-adrenergic agonist (BA) or growth hormone (GH) compared to a control cohort. Data is mean ± SEM. *Indicates a significant treatment effect with p < 0.005 (unless otherwise stated). ^#Indicates a significant treatment x time interaction with p < 0.01 (unless otherwise stated).
