Post-partum leucocytic activity and its relationship to caesarian section and retained placenta

The activity of the leucocytes of 30 cows during 10 days after parturition is described. A comparison is made between the activity of leucocytes of 10 cows after normal parturition, 10 cows after caesarian section and 10 cows with retained placenta. When compared with normal parturition, caesarian section does not have a negative influence on the activity of the leucocytes during the puerperal period, during which time however the activity of leucocytes of cows with retained placenta is strongly decreased.
