Abstract
SUMMARY Total serum immunoglobulin (ZST test), IgG, IgM and IgA levels were determined in 57 Holstein-Friesian suckled calves at five days of age and the relation observed between these and the subsequent occurrence of clinical diarrhoea in the first two months of life. A significant positive correlation was observed between total immunoglobulins, IgM and IgA levels and the health of the animals. Calves which remained healthy had significantly higher levels of IgM than those which developed diarrhoea. A positive correlation was found between the ZST test and the immunoglobulins G, M and A in the sera of neonatal calves. The importance of IgM in preventing neonatal diarrhoea is discussed.
