High-level copper feeding of swine and poultry and the ecology

OSTI ID:5824442
Copper at levels up to 250 ppm in the diet have been fed to swine and poultry as a means of increasing growth rate. Dietary copper is concentrated two- to threefold in animal wastes and may result in localized increases in soil and water copper concentrations. When discharged into bodies of water or onto the land, copper from animal waste may adversely affect growth of aquatic organisms or crops, or may increase their copper contents. Sheep are the most sensitive of the animal species to copper toxicity. Copper content of plants can exceed the levels reported to cause toxicity in sheep, but the absence of adequate dietary molybdenum appears to be a prerequisite to the production of copper toxicity with copper levels occurring naturally. 25 references, 2 tables.
