Neuropeptide Y (NPY) and peptide YY (PYY) were injected intracerebroventricularly (ICV) in broiler chicks. Both NPY and PYY markedly increased food intake during the first hour post-injection compared to saline (SAL) controls. Food intake doubled in chicks given 5 micrograms NPY. A response surface analysis suggested that following ICV injection of NPY, maximum food intake occurred, using a dose of 9 micrograms. In contrast, an estimated dose between one and 5 micrograms PYY resulted in maximum… CONTINUE READING
