ABSTRACT:
A ruminant repellent composition effective to discourage browsing of edible material, especially living vegetable matter, is the decomposition product of a lipoidal material admixed with a lipolytic enzyme. One such composition is produced by admixing fish, such as whole salmon, with a source of lipolytic enzyme, such as visceral enzyme from feeding fish, or pancreatic enzyme derived from hog or beef pancreas. The effectiveness of the mixture can be increased by admixing additional lipoidal material such as fish oil, for example, tuna oil with the fish prior to decomposition. The active portion of the decomposition product of the lipoidal material and the lipolytic enzyme can be extracted with a water immiscible, organic solvent, such as dichloromethane, to separate the water soluble phytotoxins present in the decomposition product and to concentrate the active ruminant repellent components from the decomposition product.
