Abstract
The current study was designed to evaluate the growth factors and cytokines as insulin like growth factors binding proteins (IGFBP 1-4), Interferon Tau (IFNT) and Interleukins 6 and 13 (IL-6, -13) concentrations which associated with early embryonic deaths (EED) and fetal death (FD) in dairy cattle. A total number of ninety (n=90), non-pregnant crossbreed dairy cows, 40-days postpartum were included in this study. Cows were examined using ultrasonographic examination to ensure absence of any uterine affections. Five cows were excluded due to uterine affections during examination. Estrus synchronization using GnRH, PGF2α and GnRH (GPG) regimen were applied however, another 10 cows were excluded due to showing an estrus signs after the first GnRH injection. The timed artificial insemination (AI) were applied to other cows blindly at the 10th Day of the protocol. Rectal ultrasonographic examination were applied at beginning of the synchronization, then at the 9th day of the protocol (at the second injection of GnRH). For pregnancy diagnosis, ultrasonographic examination were performed at the 20, 25, 30, 40, 50, 60, 70, 80 and 90th day after AI in all cows. Blood sampling were collected at days 0, 7, 9, 11 during synchronization then at each ultrasonographic examination post insemination. Our results revealed that thirty cows (n=30) showed endometrial thickness and some fluctuation on uterine lumen at day 20 post insemination, however only 26 cows were confirmed as pregnant but other 4 cows showed an estrus.
