To determine the usefulness of immune profile for evaluation of the immune conditions in a dairy herd, the results of the immune profile test were compared in two herd groups, one herd group with many cases of disease (diseased herd), and the other group was healthy (healthy herd). There was a 40% occurrence of peripartum disease, milk fever, displacement of abomasum and mastitis in the diseased herd. Both herds were evaluated far five milking terms. Serum total cholesterol level in the diseased herd was lower than that in the healthy herd, while on the other hand blood urea nitrogen was higher compared to the healthy herd. The number of white blood cells, neutrophils and MHC class sup+ 2 low (low fluorescence intensity ; monocyte) cells in the diseased herd increased compared to the healthy herd. The serum activity of interleukin-1 and tumor necrosis factor was higher in the diseased herd than in the healthy herd. These results suggest that there might be a disorder of immune condition in herds with sporadically occurring peripartum disease, thus immune profile is useful for evaluation of immune condition in herds.
