Title: Some effects of high dietary levels of various salts of copper in broiler chickens

Abstract

Day old female broiler chicks were housed in floor pens and fed a commercial broiler diet supplemented with graded levels (up to 720 ppM copper) of copper acetate, chloride, oxide or sulfate. At four and six weeks of age, broilers receiving the basal diet (containing 16 ppM Cu) and each high Cu supplemented treatment group were weighed and placed in individual metabolism cages. At six weeks of age, some of the birds continued to receive the same diets they had received previously and others were changed from the high Cu diets to the basal diet. All birds were individually weighed and sacrificed at eight weeks of age. Samples of liver, breast muscle, kidney, blood and excreta were analyzed for Cu by atomic absorption spectrophotometry. Samples of crop, duodenum, ileum, liver and pancreas were taken from all birds for histological observations. Parameters considered in these studies included histopathological observations, mortality, rates of growth, changes of the Cu content of various tissues and excreta (urine and feces). Calculations on the extents and rates of Cu depletion from birds receiving various sources of Cu were derived from these data. Data obtained in these trials indicate that except for copper oxide, growth was inverselymore » proportional and tissue Cu residues were directly proportional to increasing levels of dietary Cu. Histological changes of the selected portions of the gastrointestinal tract as well as mortality were not affected. All affected parameters were statistically significant (P less than or equal to .05) at the high level of Cu supplementation. 9 references, 6 tables.« less
