Worldwide, heat stress is a billion dollar problem. Institute for Global Change Adaptation Science (ICAS) at Ibaraki Univ. reported that the Agriculture in Kyushu is already severely affected
by climate change. ICAS suggested that if no action is taken now, the economic cost of climate change to Japan could be as high as ¥17 trillion annually by the end of the century. Therefore, it is very urgent to develop adaption of living organisms under changing climate. Global warming inducing high ambient temperature is a resultant of climate change. Poultry birds are very sensitive to heat stress [Chowdhury et al., 2012, 2014]. Recently, I confirmed that L-citrulline (L-Cit) clearly reduced body temperature in heat exposed chicks. Another research of mine, supported by Kiekai Research Grant, revealed that L-alanine showed declining body temperature, but not as strong as L-Cit. Therefore, I am interested to conduct further research using L-Cit to confirm its usefulness for better adaptability in chickens under high temperature. Originality: Function of L-Cit and its metabolites to control heat stress has not yet been reported. Thus, I think a novel nutrient(s) will be discovered with its potential function to overcome heat stress..

I wish to investigate the functional mechanism of some heat-stress bio-markers to determine their significance during heat-stress. Our recently identified heat-stress bio-markers are some brain neuropeptides and free amino acids in the brain and plasma. The goals of this project are a) to uncover whether the increased brain neuropeptides and altered free amino acids have some functional significance to adapt heat-stress, and b) find how supplementation of amino acids be helpful for better adaptation of organisms under warming environment..

Supplementation of food-law permitted amino acids to overcome heat-stress in chickens
2014.04～2015.03, 代表者：Vishwajit S. Chowdhury, Faculty of Arts and Science, Kyushu University, Kiekai Research Grant
Background: Heat-stress in summer is becoming a great threat on animals and humans in many tropical/subtropical countries including Japan. In general, heat-stress increases body temperature [1], decreases food intake [1, 2], live weight gain [3], and food efficiency in chickens. Therefore, it is very important to think how to over-come the adverse effect of heat-stress. Amino acids are widely used as anti-stress agents with regard to psychological and physiological stress [4]. I recently clarified that two nonessential amino acids (D-aspartate (D-Asp) and L-alanine (L-Ala)) elicited remarkable effects on body temperature in chicks. Interestingly D-Asp declined body temperature, although L-Ala increased it (Figure 1). There several reports of using essential amino acids to overcome heat-stress in chickens [5]. However, to the best of my knowledge, there is no report available of using D/DL-amino acids in this regard.
Purposes: (1) To test Japan food law (Law No.35 of 1953) permitted DL amino acids (DL-alanine, DL-tryptophan and DL-methionine) and few other D-/L-amino acids to overcome heat-stress in chickens; (2) how the D-/DL-amino acids influence the biochemical, cellular and molecular parameters related to thermoregulation and food intake.
