Recent Research on Mechanisms of Feeding Regulation in Chicks

Takaoki Saneyasu. J Poult Sci. .

Abstract

Food intake affects poultry productivity. A complete understanding of these regulatory mechanisms provides new strategies to improve productivity. Food intake is regulated by complex mechanisms involving many factors, including the central nervous system, gastrointestinal tract, hormones, and nutrients. Although several studies have been conducted to elucidate regulatory mechanisms in chickens, the mechanisms remain unclear. To update the current knowledge on feeding regulation in chickens, this review focuses on recent findings that have not been summarized in previous reviews, including spexins, adipokines, neurosecretory proteins GL and GM, and central intracellular signaling factors.

Keywords: chicken; food intake; hypothalamus; medulla oblongata.

Representative successful and unsuccessful intracerebroventricular injections in chick brain. Saline solution containing 0.1% Evans blue was injected using the method of Davis et al. (1979)[70]. Successful injection (the brain on the left) was verified by observing the presence of Evans blue in the lateral ventricle. In the brain on the right, no Evans blue was observed in the lateral ventricle, indicating that the injection had failed.
