In general, the use of arsenic acids (arsanilic acid and 3-nitro 4 hydroxyphenylarsonic) in the diets of laying hens has been observed as a slight increased rate of egg production or improved feed efficiency. However, detrimental effects can be observed with each of the arsenic acids when fed in exceptionally high energy diets. But on average, a 3% improvement in egg production has been observed. Data obtained over the past 2 years at this laboratory with the use of several antibiotics including penicillin, oleandomycin, oxytetracycline, chlortetracycline, and streptomycin plus arsanilic acid, the nitrofurans (furazolidone and nitrofurazone) and nystatin in diets for laying and breeding hens will be reported.
