Outline of Final Research Achievements

In animals, attenuation of excessive physiological stress response could be effective to prevent some diseases. The present study aimed at the establishment of nutritional science in the developmental stage to attenuate the excessive stress response. For the early step, we investigated low-molecular-weight metabolite levels in plasma and tissues in the developmental stage. It was found that some metabolite levels were influenced by the developmental stage in rats and chickens. Furthermore, we confirmed that some stressors affect some metabolite levels of plasma in rats and chickens. In addition, we investigated effects of administration of alpha-aminobutyrate, whose levels were influenced by the developmental stage, on growth and metabolite levels in plasma and tissues in rats and chickens.
