All animals were treated with an Ovuplant subcutaneous implant on 10 January. Five coyotes (*) were artificially inseminated on 22 January (Coyote B; 30% progressively motile sperm, low dose), 25 January (Coyotes B, E, and I; 80% progressively motile sperm, adequate dose), and 26 January (Coyotes D and J; 10% progressively motile sperm). Two coyotes (<$>\raster(70%)="rg1"<$>) were confirmed pregnant with 6–8 fetuses, each.
