Abstract


Colostrum from immunised cow, after skimming and coagulating with calf rennet, proved to be a potent source of blood typing reagent in bovines. The level of antibodies in the milk serum appared to be three times more than the blood serum obtained on the same day. This approach serves as an easy and reliable source of high titred blood typing reagent in bulk quantities.
