Abstract

ABSTRACT INVESTIGATIONS by Bell (1952) and Sikes et al. (1952) revealed that a chlorinated naphthalene was one causative agent of hyperkeratosis (X-disease) in cattle and aroused an interest in this laboratory in the possible toxicity of these compounds in poultry. Chlordane, a chlorinated hydrocarbon structurally similar to chlorinated naphthalene, was reported by Moore et al. (1954) to be quite toxic to poults when used in a mixture of equal parts of a 2% chlordane and 0.4% lindane spray to control ants and flies in a room housing poults. They found lindane to be nontoxic to poults when used alone as a spray. Aldrin, a chlorinated naphthalene derivative, when fed at levels of 12.5 and 25 p.p.m. to 76-day old Broad Breasted Bronze turkeys in a 42-day feeding experiment, caused mortalities of 15 and 100%, respectively, the latter occurring in 14 days (Anderson et al., 1952). No reports, however, on the influence . . .
