Knowledge of the changes in the concentrations of biochemical parameters gives the possibility to conclude about the health status of the cows, the quality of nutrition, or reproductive performance and milk productivity. The studies aimed to assess the health status of the primiparous dairy cows at the time of prospectus new fertilization and to screen the challenges of the preceding periparturient period through the analysis of protein metabolism and iron parameters in context of their potential role as markers of the reproductive status. Despite significant variations, the studies showed that homeostatic mechanisms and adaptational processes in cows organism are rather efficient during this period. Nevertheless, it should be underlined that at the time of prospectus new pregnancy higher concentration of urea, lower concentration of creatinine and iron parameters was noted, emphasizing the dysregulation of the organism condition and pointing the possible reason of/association with prospectus difficulties in further reproductive performance. If analyzed for the particular herd, these parameters may be useful in considerations about the selection of the time for new fertilization.
