It is well established that promoting the balance of nutrients and plant secondary metabolites (PSM) by feeding diverse forage physiologically improves ruminant production. However, the underlying mechanism remains unclear. To investigate the physiological mechanism related to the improvement of physiological stress tolerance, ruminants were fed diverse forage.

Lactate, triglycerides, non-esterified fatty acids, glycogen, and glucose in the yolk sac membrane, and blood glucose levels were also measured. The mRNA expression and activity were detected for all enzymes.
