Abstract
FROST (1953) reviewed and affirmed reports that chicks have a high degree of tolerance to arsenicals. Morehouse (1949 Morehouse (1954) found that 3-nitro-4-hydroxyphenylarsonic acid accelerated growth of chickens and turkeys and favorably effected the reproductive performance of New Hampshire pullets. Studies on the reproductive performance of turkey breeders (Moore et al., 1954) indicate that they are quite tolerant to high levels of arsanilic acid with respect to fertility. Other histomonostatic agents, 2-acetamido-5-nitrothiazole and 2-amino-5-nitrothiazole were studied by Price and Bottorff (1954) and were found to have no significant effects on egg production or hatchability, but significantly lower fertility was detected at some of the levels employed.Arsenic compounds have been shown to be effective in the control of histomoniasis in the turkeys by Blount (1938), Bolin and Vardiman (1941) and Morehouse and McGuire (1950). Treatment may start at an early age or it may start when the breeder hens are housed …
