Abstract

Levels of the immunoglobulins IgG and IgG(T) in serum in Norwegian horses of the breeds “Døle” and “Fjord” were determined by the quantitative radial immunodiffusion test.

No significant differences were apparent between the 2 Norwegian breeds. The immunoglobulin levels were approximately in the same range as previously reported for Shetland ponies.

Immunoglobulins could not be detected in the newborn foal. As early as 24 hrs. after birth the mean immunoglobulin level was within the adult range. After a drop during the first month of life, the immunoglobulins increased. IgG(T) rose more rapidly and to a higher level than IgG.

In 2 year old horses, IgG(T) was significantly higher than in adults, while IgG was significantly lower. IgG(T) seems to be a very important immunoglobulin in foals and young horses.

Sammendrag

Det ble foretatt bestemmelse av serumkonsentrasjoner av immunglobulinene IgG og IgG(T) hos voksne norske hester av rasene „dølehest“ og „fjording“ ved kvantitativ radial immundiffusjonstest. Av „dølehest“ ble det også gjort undersøkelse på hester 2 og 3 år garnie og på en gruppe føll på forskjellig alderstrinn etter fødsel.

Signifikant forskj ell mellom de to norske hesteraser kunne ikke påvises. Immunglobulinkonsentrasjonene var omtrentlig pa samme nivå som tidligere er angitt for Shetland ponnier.

Immunglobuliner kunne ikke påvises hos det nyfødte føll. Allerede 24 timer etter fødsel var middelkonsentrasjonene av immunglobuliner på høyde med det voksne dyrs. Etter et fall i løpet av første levemåned ble det en stigning i immunglobulinene. IgG(T) steg raskere og til et høyere nivå enn IgG.

Hos 2 år garnie hester var IgG(T) signifikant høyere enn hos voksne hester, mens IgG var signifikant lavere. IgG(T) synes å være et meget viktig immunglobulin hos føll og unghester.
