Nine lambs that had been bonded to cattle were placed with 7 heifers in pastures frequented by coyotes (Canis latrans) to determine whether multi-species grazing with bonded lambs would reduce predation. Unbonded lambs were grazed alone in a nearby pasture. Bonded lambs with cattle and unbonded lambs were rotated among pastures to reduce pasture bias. None of the bonded lambs were lost to predation during the entire 163-day study (Trials 1, 2 and 3). Four of 8 unbonded lambs were lost, presumably to predators, during a 19-day period, and 9 of 15 unbonded lambs and ewes were lost to predation during a later 43-day period. Bonding sheep to cattle may be an effective method for reducing coyote depredation on sheep.
