Body weights are presented in Figure 1a, b, and c for early middle and late xperimental ages, respectively. A significant increase in BW was observed in birds reared under GL as early as 3 d of age as compared to all other treatment groups (Figure 1a). This trend continued through 5 and 7 d of age, compared to birds reared under RL or WL. At these ages, no significant difference in BW was found between birds treated with GL and BL.
By 9 d of age, GL chicks were heavier than all other
