چکیده

All of ten calves which were permitted to take colostrum after birth survived. Eight out of twelve calves which did not get colostrum died and one was killed moribund. One calf, killed on the 27th day, harbored miscellaneous bacteria in its organs. The kidneys were sclerotic and one joint diseased. Of the remaining two calves, one had transitory joint troubles, the other rhinitis. One was sold and the other killed when 2 months old. In the latter the organs were normal and sterile.

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 prote...

The transfer of immunity to the new-born calf from colostrum.

Some years ago, Theobald Smith and his associates (1) showed that passive immunity acquired by the new-born calf from colostrum is of prime importance in protection against infectious disease. At about the same time, Orcutt and Howe (2) observed that, after the ingestion of colostrum, agglutinins appear in the calf serum associated with a globulin which is precipitable at low concentrations of ...

Effect of colostrum intake on diarrhoea incidence in new-born calves.

In a survey which lasted one year and included data of 73 dairy cows with their calves, colostrum immunoglobulin G (IgG) of 22 primiparous cows and serum IgG of their calves were lower than the corresponding IgG levels of 51 multiparous cows and their calves. Serum IgG concentration was not correlated with diarrhoea incidence. Although there were no seasonal differences in the IgG concentration...

Correlation between neonatal calf diarrhea and the level of maternally derived antibodies

Passively acquired antibodies through colostrum will protect calves against etiological agents of neonatal calf diarrhea. Among them enteric diseases due to strains of Enterotoxigenic Escherichia coli (ETEC) are the most commonly occurring form of colibacillosis in newborn calves. Specific antibodies against whole ETEC cells and total immunoglobulin G in dam serum, colostrum and calf serum were...

STUDIES ON PROTEINS FROM BOVINE COLOSTRUM III. THE HOMOLOGOUS AND HETEROLOGOUS TRANSFER OF INGESTED PROTEIN TO THE BLOOD STREAM OF THE YOUNG ANIMAL* BY R. G. HANSENt

It has been adequately demonstrated that the new-born calf and kid acquire antibody proteins from ingested colostrum (1). These immune proteins appear in the blood stream of the young animal in a form immunologically indistinguishable from that in the colostrum (1). This apparent passage of intact protein through the gastrointestinal tract of the calf and kid is characteristic of the first few ...
