The immunoglobulin levels of Norwegian horses (Doele and Fjord breeds) were same as reported earlier for Shetland ponies (see V.B. 41, abst. 2422). Immunoglobulins could not be detected in the newborn foal. As early as 24 hours 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.
