Serum samples, collected monthly from January through December 1988 from 10 cows, their calves, and 10 yearling heifers, were used to determine total and Ostertagia-specific IgE levels. In addition, serum pepsinogen concentration, fecal egg counts, and body weights were measured. The following observations were made. (1) Total and Ostertagia-specific IgE levels followed similar seasonal patterns, being generally highest in the spring. (2) Breed and/or sire effects on total IgE levels were observed, with cattle from Angus-cross lines having higher levels than cattle of the other breeds tested. (3) Based on fecal egg counts, adult populations of Ostertagia ostertagi paralleled circulating IgE levels in the calves.
