Published data from controlled studies do not in all cases substantiate the prophylactic and therapeutic value of cupric sulfate at high levels (0.05 to 0.10 per cent) in feed or drinking water. Field reports have for many years favored the use of cupric sulfate as an antifungal or antimycotic agent, he added. • Copper was recognized as an essential nutrient for poultry in 1929, according to Dr. Sullivan. Poultry requirements vary from 2 to 10 p.p.m. of copper. High levels of copper in the diet of young birds will in crease body weight gain and improve feed efficiency. He pointed out, however, that these responses have been less consistent and of lower magnitude than obtained with various antibiotics.

Dr. Sullivan listed some risks or dangers associated with high levels of copper in poultry diets; 1. High levels of dietary copper reduce or cancel the antihistominal activity and perhaps the antibacterial activity of arsenic acid compounds (nitarsone, oarbarsone and arsanilic acid). 2. The “growth promoting” activity of penicillin, streptomycin, the tetracyclines and perhaps other antibiotics is reduced by the presence of 120 to 240 p.p.m. of dietary copper. 3. Feeding high levels of cupric sulfate or cupric oxide greatly increases the level of copper in poultry manure and litter. The in fluence of high copper manures on soil chemistry and productivity is not known. 4. The human health ng to my frog."
