Synchronization schedule, heat detection and treatment regimes for heifers used in the study. Heifers were injected with Estrumate® 11 days apart and observed for heats after the second injection. All heifers were observed in standing heat within the same twelve hour period then observed for one cycle length of 18–20 days. Twelve days after non-induced estrus, heifers were injected a third time and observed for heats. At 6 pm, fourteen days following standing heat treatment began. Heifers received four uterine infusions 12 hr apart of either saline control, IFN-τ, estrogen or ICI 182,780. At 2 pm on day 16 of the estrous cycle, heifers were slaughtered and tissues were collected for analysis.
