How high incubation temperature affects embryonic broilers

In a recent study, researchers shed light on the effect of high incubation temperature from embryonic day 12 to day of hatch on the expression and abundance of tight junction proteins, junctional adhesion molecules and heat shock proteins in the yolk sac tissue and small intestine of embryonic broilers. During the transition from incubation to hatch, chicks shift from obtaining nutrients from the yolk sac to the intestine. The yolk sac tissue and small intestine serve as biological barriers b
