SALMON POISONING DISEASE: RESEARCH ON A POTENTIAL METHOD OF LETHAL CONTROL FOR COYOTES

Salmon poisoning disease (SPD) was tested as a potential method of lethal control for coyotes (Canis latrans). Fresh fish containing the agents for SPD was fed to 72 captive adult coyotes. Coho (Oncorhunchus kisutch) and steel head salmon (Salmo gairdneri) from Oregon hatcheries were the principal species of fish used. Coyotes that ate the fish developed observable signs of SPD in a mean of 8 days. The overall rate of mortality was 50%, and death occurred in a mean of 20 days from consuming fish. Coyotes that died from SPD lost a mean of 32% of their body weight during the course of the disease. Other coyotes were fed preserved fish samples or administered oral or intraperitoneal treatments of lymph node matter from coyotes that died from SPD. In light of the relatively low rate of mortality observed, feeding coyotes fish to cause death from SPD appears to be a method of questionable value for controlling numbers of adult coyotes in areas of livestock production unless fish with a highly virulent strain of the SPD agent can be obtained

New Construction Ideas for Healthier Pigs -- Flushing System

Food Discards for Swine

The intent of this fact sheet is to provide introductory information on swine production that has been tested on Pacific island farms. This publication provides information on preparation of cooked food waste for use as swine feed.Funded by the United States Department of Agriculture Cooperative State Research, Education and Extension Service Grant 99-38826-785

Biogas Digesters

The intent of this fact sheet is to provide introductory information on swine waste management methods that have been tested on Pacific island farms. Biogas digesters yield three products: biogas, liquid effluent, and a semi-solid sludge. The biogas can be used for productive purposes, such as firing an animal food cooker or heating water. The sludge retains most of the initial phosphorous and potassium.Funded by the United States Department of Agriculture Cooperative State Research, Education and Extension Service Grant 99-38826-785
