We report serum IGF-I, non-esterified fatty acids [NEFA], beta hydroxybutyrate [BHB] and glucose concentrations in dairy cows with endometritis puerperalis and cystic ovarian disease. We trialed 87 lactating Holstein cows with 1 to 7 parities at 9th month pregnancy. Controls were cows without disease. Blood was taken 2 weeks before, and 2, 4 and 6 weeks after calving. Cows were palpated 2, 4 and 6 weeks after calving, examined for discharges and intra-vaginally. In pregnant cows, ultrasonography of uterus, ovaries, corpus luteum and cysts were done. In cows with endometritis, after partus we observed 67-78% declines in serum IGF, 28% fatty acid and 32-43%% in glucose (P < 0.05) with calving delayed 22 days and ovulation 6 days. In cows with cysts IGF was ~14% lower and BHB ~17% higher (P < 0.05). Partus was associated with declines of 59 to 78% in serum IGF and glucose 46% (P < 0.05). Results suggest that higher IGF-I before partus may inhibit formation of ovarian cysts and endometritis after partus in dairy cattle.
