Effect of intracerebroventricular injection of PCPA (1.5 μg) followed by N/OFQ (16 nmol) on food intake in chickens: Saline 0.9 % NaCl, PCPA parachlorophenylalanine, N/OFQ nociceptin/orphanin FQ. Data are presented as mean ± SEM. There are significant differences between groups with different codes in a column in each time (superscript letters a, b, c; p < 0.05)
