Wolves are apex predators that typically hunt wild ungulates like deer, elk, and moose. However, wolves can and do prey on domestic goats, especially under specific circumstances in areas where wolf populations are present. This predation represents a significant concern for goat owners.
Wolves and Goats: The Predatory Relationship
Wolves are adaptable, opportunistic carnivores with a varied diet. While their primary diet consists of large, wild hoofed animals, they exploit other food sources when available. Domestic goats, often lacking natural defenses, can become susceptible targets. This predation is a consequence of opportunity and proximity to livestock, not a primary hunting preference.
Studies indicate wolves generally prefer wild prey, even when livestock is abundant. A review of 119 grey wolf dietary studies found wild prey constituted approximately 65% of their diet, while livestock accounted for about 13% of the biomass consumed. However, if wild prey populations are scarce, wolves may turn to domestic animals. This adaptability allows wolves to thrive, impacting livestock when conditions favor such interactions.
Factors Driving Wolf Predation on Goats
Several conditions increase the likelihood of wolves preying on goats. Goats pastured near active wolf habitats are at higher risk. When natural prey populations, such as deer or elk, are low, wolves may shift their focus to more readily available livestock. This dietary flexibility helps wolves survive during wild prey scarcity.
Livestock vulnerability also attracts wolf predation. Unattended goats, those in pastures with inadequate fencing, or young, sick, or injured animals become easier targets. Successful predation can lead wolves to develop a learned behavior, causing them to continue targeting domestic animals. Herd size and composition also influence susceptibility; smaller, more dispersed herds are more vulnerable.
Strategies for Protecting Goats from Wolves
Protecting goats from wolf predation involves non-lethal deterrents and management practices. Robust fencing, such as high-tensile electric fences, is effective. These fences should be at least 5-6 feet tall with closely spaced, electrified wires near the ground to deter jumping and crawling. Fladry, a line with colorful flags, can also provide a temporary visual deterrent.
Livestock guardian animals can significantly reduce predation risk. Breeds like Great Pyrenees, Anatolian Shepherds, and Akbash dogs are specifically bred to protect livestock. Donkeys and llamas also serve as guardians, as they are territorial and may aggressively confront intruders. These animals bond with the herd and act as a constant deterrent.
Herd management practices are important. Penning goats at night in secure enclosures or bringing them closer to human activity provides protection, as wolves generally avoid human presence. Properly disposing of deceased animals avoids attracting scavengers and predators. Employing lighting and noise deterrents, such as flashing lights or loud sounds, can scare wolves away. Consistent human presence through monitoring and patrolling also deters wolves.
