AB  - The objective of the present study was to estimate metabolic status in Holstein dairy
cows during different stages of lactation, on the basis changes of blood
concentrations of selected biochemical markers. Blood samples were collected from
100 Holstein dairy cows and blood serum parameters were evaluated. The cows
were allocated to four groups according to the production period, including Group 1 –
cows in early lactation (n=18), Group 2 – cows in full lactation (n=26), Group 3 –
cows in mid lactation (n=25), and Group 4 – cows in late lactation (n=31). Statistically
significant differences (P < 0.01) were found between the experimental groups of
cows in blood NEFA, BHB, TP, TG, TChol, urea, globulin, levels, and enzyme
activities of AST, ALT, ALP, GGT and LDH. The intensity of lipomobilisation (NEFA
or BHB concentrations) correlated positively (P < 0.05) with the markers of cell
damage or liver function impairment (tBIL.,serum AST, ALT, LDH and GGT
activities), but negatively (P < 0.05) with the circulating concentrations of compounds
synthesised in liver (glucose, TG and urea). All these biochemical metabolites may
be used as important biochemical markers in the determination of the metabolic
status in high-yielding dairy cows.

AB  - The reproductive efficiency of the cows was monitored after two resynchronization protocols: Ovsynch (OVS) and Double Ovsynch (DOS). The research initially included 70 HF cows who entered the first synchronization protocol - Presynch. Cows that did not conceive after the first synchronization were divided into two groups and introduced to two resynchronization protocols. In the first group of cows (n=35), the DOS protocol began with the application of GnRH on day 22 after the Presynch TAI (Timed Artificial Insemination), and seven days later pregnancy check-up was done and PGF2α was applied only to non-pregnant cows (n=23), which remained in the study. In the second group of cows, the OVS protocol started on day 32 after Presynch TAI only in non-pregnant animals (n=20). Progesterone (P4) concentration was determined at the time of application of GnRH1, PGF2α and GnRH2 in both groups of cows, and then 30 days after Resynch TAI, ultrasound pregnancy diagnosis was done. A higher percentage of pregnant cows were recorded in the OVS group compared to the DOS group (45% and 35%, respectively). The concentration of P4 in the serum of cows in the DOS group during the first measurement (GnRH1) was significantly higher than the value in cows that did not conceive (p<0.05), while in the third measurement (GnRH2) the average concentration of P4 in conceiving cows was significantly lower (p<0.001) compared to cows that did not coincive. The open days period was significantly longer in pregnant cows that were resynchronized using the DOS protocol compared to cows from the OVS protocol. In conclusion, the OVS protocol of estrus resynchronization in dairy cows proved to be more successful than the DOS protocol. However, considering the advantages the OVS, it is needed to determine which day of the sexual cycle is the best to start resynchronization.

AB  - Peripartal period in dairy cows includes 3 weeks ante partum and 3
weeks post partum (transition period). The transition period represents the
most challenging phase in the life of dairy cows, because the body occurring
metabolic, endocrine, immune and reproductive changes that affect the
animal health and production efficiency. During the transition period (the
late gestation and early lactation) in response to metabolic stress, in dairy
cows can develop numerous pathophysiological mechanisms (inflammation,
insulin resistance and metabolic adaptation). Numerous mechanisms are
activated in the organism of dairy cows, the main role of which is
maintenance of homeostatic and homeostatic functions of all tissues, organs
and organ systems. In regulation of these processes, heat stress proteins
HSP70 play a key role.
