The concentrations of IGF-1 in the breast muscle of broilers. IGF-1 (insulin-like growth factor-1) was measured by chicken-specific ELISA on 38-day-old male broilers. Each bar represents mean ± standard error (SE) of ten replicates. Means with no common letter differ significantly (P < 0.05). H = fast-growing broilers (heavy BW); M = medium-growing broilers (average BW); L = slow-growing broilers (low BW)
