Absolute (a) and relative breast muscle weight (b) of three groups of broilers. The relative breast muscle weight is the ratio of absolute breast muscle weight to BW. Each bar represents mean ± standard error (SE) of thirty, 38-day-old male broilers per group. 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)
