Grey wolf (Canis lupus), golden jackal (Canis aureus), coyote (Canis latrans) and stray dog (Canis familiaris) are having increasing population trends in Europe and the United States, fuelling human-predator conflict. Predation on livestock is causing devastating losses both in terms of finance and resources to local communities. We investigated the extent to which these canine predators depend on livestock as their food source by performing a systematic literature analysis. We predicted that the wolf feeds the most livestock and selects larger domestic animals compared to jackals, coyotes and dogs. The information retrieved from 115 scientific publications included the frequency of occurrence (%O) and biomass proportion (%B) of livestock species in the predators’ diet. Our analyses revealed that wolves consumed significantly more livestock than the golden jackal and coyote. Statistical analyses indicated that in case of wolves, cattle and goats were chosen the most compared to any other species of livestock. For jackals the consumption of pig was significantly higher than equines and sheep. There was little data on coyotes and dogs, although we found higher consumption of pig compared to the cattle in case of coyotes and no differences in livestock species consumption frequencies in case of dogs. Most studies reported that domestic species in wolf diets have been observed in areas where the wild prey availability is degraded. Predator management differs among countries and is continuously influenced by a number of unique, local factors modifying the predation rates and the intensity of this human-wildlife conflict. It is a priority to identify the real mechanism and cause of the livestock predation and set adaptive steps for its elimination.
