Figure 4: Effect of cerulenin treatment on plasma leptin levels (A) and cumulative food intake (B) in broiler chickens: Two homogenous weightmatched groups of 2-wk-old broiler chickens (n = 4) were intravenously treated with cerulenin (15 mg/kg at 0, 4, and 24h) or RPMI medium as a control. Cumulative food intake was monitored after 28h and plasma leptin levels were measured by RIA as described in materials and methods. Data are presented as mean ± SEM and * different from the control, P<0.05.
