“…Higher concentrations of α 1acid glycoprotein, haptoglobin and ceruloplasmin were found also by Sheldon et al (2001) in cows with uterine bacterial contamination. However, according to Kurpińska et al (2014), the changes in the concentrations of some serum proteins during the periparturient period should not be considered as a result of pathological processes. Regassa and Noakes (1999) concluded also that the physiological processes taking place around the time of parturition, especially increase in myometrial activity, involution of the uterus, as well as degeneration and regeneration of the endometrium, may also be responsible for higher concentrations of acute phase proteins in blood serum of cows after calving.…”

“…Cows undergo serious metabolic and physiological changes during these periods (Tanaka et al 2011). These changes are connected with the growth and development of the foetus, preparation of the mammary gland for lactation, regeneration of the reproductive system after parturition, as well as preparation for new fertilization and pregnancy (Kurpińska et al 2014). Moreover, these physiological changes may induce stress and affect the metabolic processes (Tanritanir et al 2009;Van Dorland et al 2009).…”

This study was aimed at the evaluation of changes in the concentrations of serum protein fractions in 10 clinically healthy dairy cows in the period from 1 week before to 6 weeks after calving. Serum was analysed for total protein concentrations, and the relative and absolute values of protein fractionsalbumin, alpha 1-(α 1), alpha 2-(α 2), beta 1-(β 1), beta 2-(β 2), and gamma-(γ) globulins. The concentrations of total proteins increased significantly from week 1 before parturition till the end of the sixth week of lactation (P < .001). In the concentrations of albumin, a slight decrease was observed 1 week after parturition, with a further decrease till the end of the study. The concentrations of α 1-and α 2-globulins increased significantly during the early stages of postpartal period (P < .01 and P < .001). The concentrations of β 2-globulins showed an increasing trend after calving (P < .001). The concentrations of γ-globulins increased 3 and 6 weeks after calving (P < .001). These results showed dynamic changes in the serum protein electrophoretic pattern during peripartum period which reflect the physiological response of the organism to the variation of metabolic and immune functions occurring from gestational non-lactating to a non-gestational lactating state in periparturient dairy cows.

“…Hormonal changes during periparturient period are abrupt. Optimal concentration of hormones is crucial for maintaining health of mother, fetus and calf, course of parturition without complications, initiation of lactation and preparation of mother's organism for new pregnancy [Kornmatitsuk et al 2003, Kindahl et al 2002, 2004Skrzypczak et al 2005, Herosimczyk et al 2013, Kurpińska et al 2014, 2016Wankhade et al 2017, Mikuła et al 2018, Kurpińska et al 2019, Lucy 2019. The most important hormones involved in the regulation of pregnancy are: progesterone, estrogens, androgens, placental lactogen, relaxin, PAGs (pregnancy-associated glycoproteins).…”

In the last month of pregnancy and the first weeks of lactation, intensive adaptations processes, both morphological and functional, take place in the cow's body. An organism adapts through changes in the intensity of metabolic processes and the activity of its regulatory mechanisms. Maintaining the homeostasis of an organism in prepartum and postpartum periods is the key condition in health maintaining of the mother and the foetus/calf. This paper presents studies on changes in the levels of progesterone, estrogens, androgens, placental lactogen, relaxin, pregnancy glycoproteins, prostaglandin F2α, cortisol, oxytocin, prolactin, GnRH, LH, FSH, thyroid hormones, insulin and growth hormone, significantly associated with the growth and development of the foetus, preparation of the mammary glands for lactation, and, after parturition, with reproductive system regeneration and preparation for new fertilization and pregnancy.

“…Analysis of blood plasma with the aid of proteomic tools enables a comprehensive description of animal health status and indicates potential health problems, making them available for therapeutic solutions. Proteomic studies in cows during the periparturient period are sparse in context of their high potential and may provide valuable information for veterinary practice (Kupczyński and Chudoba-Drozdowska, 2002;Kindahl et al, 2004;Lippolis and Reinhardt, 2008;Chen et al, 2014;Kurpińska et al, 2014;Ożgo et al, 2015).…”

details of feeding shown in Table 1). Blood, the material for analysis, was drawn from the external jugular vein and collected using sterile needles and tubes with anticoagulant (EDTA K 3). Collection of samples was performed at the following points: 30, 14, and 7 days before parturition and 1, 7, 14, 30, and 60 days after calving. Blood was collected each time from the same animals, and groups were formed according to the sampling date; thus, each experimental group consisted of 10 animals. The total number of samples was 80. Blood samples were centrifuged (3000 rpm, 4 ºC), and the resulting plasma samples were stored at-80 °C until analysis. The local ethics committee for experiments on animals in Szczecin approved the design of the experiment (resolution no.
