Abstract :
The object of this study was to evaluate the independent effect different concentration of beta-hydroxybutyrate (2.4 & 4.8 mmol/ml) and estradiol (20&400 pg/ml) on the functions phagocytosis and Nitroblue tetrazolium reduction test or respiratory burst of isolated ovine neutrophils in vitro. Isolated neutrophils of sheep were incubated for one hour in room temperature with the previously treatments. The study consisted of 7 treatments in 5 replicates and both phagocytosis and NBT tests of tests were performed in every treatment. The Results of this study indicated that 2.4 & 4.8 mmol/ml concentrations of beta-hydroxybutyrate and estrodiol concentrations of 20 & 400 pg/ml significantly (p<0.01) reduced the percentage of phagocytosis and NBT reduction test of sheep neutrophils and this could be the reason for the suppression of the immune system in peripartureint sheep.
