Fig. 1.
Cytometric analysis of phagocytosis activity of neutrophils (A and B) and monocytes (C and D) in the peripheral blood of cows at various periods of lactation (mean ± standard error of the mean). DBD – day before drying; DBP – day before parturition; DPP – day postpartum; Experimental – cows provided with probiotic (n = 10); Control – cows without probiotic (n = 10); Phagocytic cells (%) – percentage of neutrophils and monocytes that had engulfed bacteria; MFI – mean fluorescence intensities expressing individual cellular phagocytic activity (number of bacteria per cell). Statistical significance – * p ≤ 0.05; ** p ≤ 0.01 with respect to the control; a–c – significant differences between the results for the material collected at different times in the group (P-value < 0.01)

Fig. 2.
Cytometric analysis of oxidative burst activity of neutrophils (A and B) in the peripheral blood of cows at various periods of lactation (mean ± standard error of the mean). DBD – day before drying; DBP – day before parturition; DPP – day postpartum; Experimental – cows provided with probiotic (n = 10); Control – cows without probiotic (n = 10); Phagocytic cells (%) – the percentage of phagocytic cells that produced reactive oxygen substrates (measured by the conversion of DHR123 to R123); MFI – mean fluorescence intensities expressing enzymatic activity of phagocytic cells (measured by the amount of R123 per cell). Statistical significance – * p ≤ 0.05; ** p ≤ 0.01 with respect to the control; a–c – differences between the results for the material collected at different times in the group (P-value < 0.01)
