Relative Effectiveness Of Various Breeds Of Livestock Guarding Dogs For Reducing Predation On Domestic Sheep In Colorado, William F. Andelt, Stuart N. Hopper
Relative Effectiveness Of Various Breeds Of Livestock Guarding Dogs For Reducing Predation On Domestic Sheep In Colorado, William F. Andelt, Stuart N. Hopper
Great Plains Wildlife Damage Control Workshop Proceedings
We surveyed 59 livestock producers that used multiple breeds of livestock guarding dogs to determine their ratings of the relative effectiveness of guarding dogs for deterring predation on domestic sheep in Colorado during 1995. Significantly (P < 0.05) more producers rated Akbash dogs as more effective than Great Pyrenees for deterring predation by coyotes (Canis latrans), black bears (Ursus americanus), mountain lions (Felis concolor), domestic dogs, and all predators combined. Significantly more producers also rated Akbash dogs as more effective than Komondors for deterring predation by coyotes and all predators combined. Great Pyrenees and Komondors were rated as similar in effectiveness for deterring predation. Significantly more producers rated Akbash dogs as more aggressive, …
Sheep Predation By Coyotes: A Behavioral Analysis, Ray T. Sterner
Sheep Predation By Coyotes: A Behavioral Analysis, Ray T. Sterner
Great Plains Wildlife Damage Control Workshop Proceedings
This paper presents (1) a brief overview of several concepts important to predator-prey behaviors of coyotes, (2) results of an enclosure study of sheep-attack, -immobilization, and -ingestion responses involving 12 male coyotes (Canis latrans) that were paired with sheep after observing various sheep- predation events by conspecifics, and (3) an analysis of sheep predation based upon operant learning principles. Contrasts between comparative psychological and ethological approaches to the study of animal behavior are described. Results of the enclosure study (0.127-ha) showed that following matched-length trials of observing predation, non-predation, and lone sheep, 3, 2, and 1 coyote(s), respectively, …
Livestock Protection Collar Use In California, Robert M. Timm, Gary D. Simmons, John R. Hays
Livestock Protection Collar Use In California, Robert M. Timm, Gary D. Simmons, John R. Hays
Great Plains Wildlife Damage Control Workshop Proceedings
Use of the Livestock Protection Collar (LP Collar) containing sodium fluoroacetate began on a research basis in October 1995 at the UC Hopland Research and Extension Center. Registration for use in California only by certified ADC specialists was granted in early 1996, and operational use in three north coast counties began in early 1997. Preparation for beginning operational use dealt with concerns regarding user certification, hazardous waste disposal, and public relations. We report on the success to date of using LP Collars to remove sheep-killing coyotes. Incidents in which non-target predators including mountain lions have attacked LP-Collared sheep are also …
