A.S. Series 72-32
Previous work at the South Dakota station reported in A.S. Series 71-33 has shown that pigs fed 250 parts per million (ppm) copper in the diet have an increased rate of gain with the greatest response occurring during the early growth period. Livercopper stores are elevated by feeding 250 ppm of copper. The experiment reported herein was designed to study the effectiveness of various levels of dietary copper as well as to determine the carry-over effect of copper treatments administered only during an initial 8-week treatment period. The antibiotic tylosin was included as one treatment to aid in evaluating the copper effect.
