蛋鸡的摄食行为特点与产蛋的关系及其机理

Development of Food Intake Data Acquisition System (FIDAS) and application of this system to the observation on the feed intake of young hens. The data, which acquired by FIDAS included the feed intake, the time of feed intake and the number of meal. Study the effect of environmental factors on the feed intake and egg laying performance hens. Study the role of physiological regulators (isoflavonoids, GABA and F89) in control of feed intake and laying performance in hens and the endocrine and molecular mechanisms involved.

研究正常条件下蛋鸡摄食和产蛋行为模式，从整体、神经内分泌、分子水平上探索其机理。研究环境（包括高温、营养水平、光照和饲养方式）对采食、产蛋行为的影响以及阿片摄食系统、生长轴和生殖轴在激素分泌、受体和基因水平的变化机理，为最佳环境的选择提供依据。项目探索促进食欲和提高产蛋的新方法，不但促进学科发展，而且有应用前景。
