The Relation between the Ingestion of Colostrum or Blood Serum and the Appearance of Globulin and Albumin in the Blood and Urine of the New-born Calf

The coincidence of the appearance of euglobulin and pseudo-globulin I in the blood and urine of the new-born calf following the ingestion of colostrum and the absence of these proteins when milk is fed support the inference that the proteinuria of the new-born calf is due to the ingestion of colostrum. In this passage the proteins are in part unaltered. The absorption and excretion of the proteins of blood serum have been observed. The high protein content of the feces of young calves-during the first few days-is to be ascribed, in part at least, to ingested colostrum.
