Abstract: The objective of this manuscript was to evaluate the effect of ambient temperature on the uterus flushing out during the embryo transfer process. The study was carried out on dairy farms and was performed from January 7 to November 19, 2010. The milking cow donors flushed out during hot weather were compared with donors that were flushed out during cold weather. It focused on the number of embryos obtained and the ambient temperature. The number of embryos obtained was recorded during the embryo transfer process. The three groups of milking cows were measured during high ambient temperature, medium ambient temperature and low ambient temperature while they were in heat. The experiment was performed on the Holstein breed of dairy cow. The experiment focused on the viable embryos present in the flushed liquid. The number of embryos obtained while the cows were in heat fluctuated with the difference in ambient temperatures, being the lowest during high ambient temperature. The number of embryos was high during medium ambient temperature and during low ambient temperature. Low ambient temperature had no significant effect on the number of embryos. Because high ambient temperature has a significant negative effect on the number of embryos obtained, it seems necessary to protect milking cows that are in heat against high ambient temperatures.
