Abstract: Negative energy balance (NEB) after calving leads to unique metabolic changes in cows and it provides important information on the period when nutrient output prevails over nutrient intake associated with a number of physiological changes in the organism suitable for detection using biochemical blood analyses. The aim of this paper is to summarise current knowledge of the changes in blood parameters during the period of NEB in relation to non-esterified fatty acids, ketone bodies, and immunologic and stress indicators. The impact of these changes on bovine reproduction and health is also discussed in the sequel. The period of NEB is still a very pertinent area of research as it provides a new insight into connections between physiological systems, to wit, ​​immunology, manifestation of various stress indicators, including oxidative stress, and heat shock proteins inter alia. Understanding the physiological changes during NEB is crucial for successful management of the transition period and subsequent overall good animal health and productivity.
