The influence of probiotic administration on the phagocytic and oxidative burst activity of neutrophils and monocytes in the peripheral blood of dairy cows during different lactation periods

Abstract

The objective of this bovine peripheral blood study was a comparative assessment of the phagocytic activity of neutrophils and monocytes and of the intracellular killing capacity of neutrophils from cows given no probiotic and from cows which were administered a probiotic consisting of Saccharomyces cerevisiae, Lactobacillus acidophilus, Lactobacillus plantarum and Rhodopseudomonas palustris. These activity types were compared during different lactation periods.
