Abstract

Feed intake is one of the crucial factors that affect the growth performance of broilers. Generally, a small proportion of the nutrients are used to maintain basic life metabolism, and the most of the nutrients are used to guarantee the better production performance of broilers. Hypothalamus is an important part of the central nervous system, which regulates the feed intake of animals. Hypothalamus can be integrated peripheral environment and all kinds of signals, which makes the body to generate appropriate responses for achieving adaptation, and ultimately affects the feed intake of the poultry. Thermal environment factors are critical factors that influence chicken feeding behaviors in the process of production and the growth performance. In this paper, thermal environment factors and their influences on broiler feed intake behavior, hypothalamus integrating feed intake signals and regulation mechanisms, and thermal signal molecules were reviewed to give a theoretical basis for thermal environment control in broiler production.
