Abstract

World per capita consumption of fresh dairy products is projected to increase by 1.0% p.a. and production is projected to grow at 1.6% p.a. over the coming decade (2020–2029). To meet up this additional demand, raising high producing dairy cows with proper nutrition and environment is obvious in the modern dairy industry. However, the high-yielding dairy cows are more susceptible to nutritional and environmental stresses than the lower milk-producing cows. This review discusses how exposure to nutritional and environmental stresses can cause abnormalities in mammary epithelial cells (MEC), the site of milk synthesis. In addition, the intracellular mechanisms related to milk yield are described. Recent accumulated data suggested that the unfolded protein response (UPR)-induced increase in endoplasmic reticulum biogenesis and MEC loss as the mechanism for the increase and decrease in milk yield, respectively. Therefore, an understanding of the role of ER biogenesis in enhancing secretory activities and MEC death to reduce milk yield in the context of UPR at early lactation, will be helpful for the final setup of an average lactation persistency and the producers to overcome the economic loss due to heat stress in the dairy industry.
