Central administration of galanin-like peptide (GALP) causes short-term orexigenic effects in broilers: Mediatory role of NPY1 and D1 receptors.

Studies conducted on mammalian models have indicated the role of galanin-like peptide (GALP) in appetite regulation. For the first time, the present study examines the effects of this peptide on feed consumption and behavioral changes, as well as its interaction with dopaminergic and neuropeptide Y (NPY) systems in broilers. In experiment 1, broilers were injected with GALP (0.

Central and Peripheral Effects of Lipopolysaccharide on Food Choice and Macronutrient Selection in Meat-Type Chick.

This report aimed to determine the effect of lipopolysaccharide (LPS) on food intake in broiler chicks with different rations. All birds received a starter diet until five days of age, but experimental diets were provided on days of injections. In experimental group one, chickens received an intracerebroventricular (ICV) injection of LPS (25, 50, and 100 ng) with a standard diet.
