Narongsak Chaiyabutr is Professor Emeritus of Veterinary Physiology, Chulalongkorn University, Thailand. He obtained his DVM from the same university, and an MS in Physiology from Mahidol University, Thailand. He completed postgraduate training in Animal Physiology and Biochemistry under an FAO fellowship at the Royal Veterinary and Agricultural University, Denmark. He was awarded a Ph.D. with his research study at the Hannah Research Institute, Glasgow University, Scotland, UK. His current research is centered on the study of the control mechanism of mammary function during exposure to high ambient temperature in both dairy goats and crossbred dairy cattle in the tropics, relating the utilization of glucose for the synthesis of milk components in the mammary gland.

Milk Protein - New Research Approaches discusses the biology and synthesis of milk protein at both the cellular and molecular levels. It also presents related information on animal nutrition and management, including animal breeding. It is a useful resource for students, researchers, and professionals in veterinary, dairy, food, and animal science, among others.

Effects of High Ambient Temperature on Milk Protein Synthesis in Dairy Cows and Goats: Insights from the Molecular Mechanism Studies

By Sumpun Thammacharoen, Nungnuch Saipin, Thiet Nguyen and Narongsak Chaiyabutr

Milk protein is well accepted for nutritional value compared with other sources of protein. Detailed understanding of the natural factors that can determine milk protein subcomponent (i.e., casein) not only fulfill the knowledge of protein synthesis but also provide the potential idea to improve milk quality. The variation in milk protein content from dairy cows and goats fed in tropical areas may determine the added value of milk from this region. Under prolonged high ambient temperature (HTa), dairy cows and goats are at the stage of heat stress. This physiological condition produces a negative effect on dairy cows and goats, i.e., food intake and milk yield. However, the higher milk protein content during summer is demonstrated in dairy goats in our condition. Likewise, an increase in heat shock protein 70 (Hsp70) gene expression from mammary epithelium cells isolated from either in vivo (summer and winter periods) and in vitro conditions suggests the direct effect of HTa on mammary gland and perhaps on milk protein synthesis. The intracellular effect of Hsp70 on milk protein synthesis has been proposed in regard to the endoplasmic reticulum and Golgi apparatus protein transportation and with the subcomponent of casein micelle. The present information reveals the molecular mechanism of HTa on milk protein synthesis.
