We have investigated the possible linkage between serum and uterine fluid immunoglobulin G (IgG) levels and the hormonal status of the cow. In cycling cows there was a significant (P < 0.01) drop in average (of 4 consecutive days) serum IgG levels, from 36.4±6.7 mg ml-1 during the luteal phase of the estrous cycle to 28.3±5.3 mg ml-1 during and around estrus. In prepartum cows, there was a significant drop (P < 0.01) from an average of 37.6±3.7 mg ml-1 from 5 consecutive days, i.e. 11-7 before parturition, to 28.0±5.5 mg ml-1 on the day of parturition. Total IgG in the uterine fluid ranged from 30 to 115 mg in one horn and from 24 mg ml-1 to 70 mg ml-1 in the other horn during the luteal phase, but was essentially undetectable at estrus. The drop in serum and uterine IgG occurred concomitantly with the drop in peripheral serum progesterone, from 2-3 ng ml-1 at the luteal phase, and 11-7 days before calving to less than 0.5 ng ml-1 around estrus and calving. Data suggest a possible linkage between steroid hormone and IgG levels. © 1995.
