[Numerical variations in the platelets in blood taken from the jugular vein of cattle, in relation to the stage of the oestrous cycle].
The variations in the blood platelet counts were determined in cows during the oestrous cycle. The results confirmed the existence of variations and considerable fluctuations and also revealed an absolute minimal value constantly found at oestrus, and relative minima on the 7th and 14th day after oestrus. The changes in the blood platelet counts are discussed.
