Abstract

In this experiment, producing layers were exposed to 4 weeks of cyclic heat to better understand the effects of heat stress on the gene expression in the cecal tonsil (CT). CT is the immune tissue located at the junction between the ileum and the ceca within the digestive tract. CT has been suggested to have a role in the regulation of the cecal content, which may have an impact on nutrient absorption. Knowledge of specific changes in gene expression at the CT highlights potential mechanisms that the tissue utilizes to alleviate the effect from heat stress.
