温热环境因子影响肉鸡采食的调控机制
Research Progress of Regulatory Mechanism of Thermal Environment Factors on Feed Intake in Broilers
摘要
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.关键词
