Use taste-aversion to reduce predation of livestock by mammals to deter human-wildlife conflict Terrestrial Mammal Conservation

A replicated, controlled, before-and-after study (year not stated) on captive animals in the USA (Gustavson et al. 1974) found that after conditioned taste-aversion treatment, coyotes Canis latrans did not catch and eat live lambs or rabbits. After one or two meals of lamb or rabbit meat containing lithium chloride (which causes gastrointestinal discomfort), six coyotes did not attack either lambs or rabbits. Three coyotes were held in individual pens. Over a 13-day period, coyotes alternated between being let into an enclosure with a live lamb or rabbit or with lamb meat containing lithium chloride. A similar experimental procedure was carried out with three different coyotes, which received rabbit meat containing lithium chloride.
