Evaluation of poultry production techniques by innate immune and development of efficient production technologies

提出了一种寻找非抗生素型促生长物质的试验方法，以通过饲喂抗生素促生长剂来模拟有意免疫相关介质的变化。即，通过在孵化后5或14天向雏鸡喂食供试品后收集小肠上部，以研究先天免疫相关因子的基因表达。此外，提出了较好的出雏后投喂时间和投喂物质，以更好地发挥肠道免疫功能。

A test method to search for non-antibiotic-type growth-promoting substances are propsed in order to mimic changes in intentional immune related mediators by feeding antibiotic growth promoters. That is, by the upper small intestine collected 5 or 14 days after the test substance fed to the chicks after hatching, to investigate the gene expression of innate immunity-related factors. In addition, we present better feeding time and substances after hatching to develop intestinal immune function well.
