Fertilized hens' eggs were externally treated with 2,4-dichlorophenoxyacetic (2,4-D) butyl ester (2.4 mg/egg) before starting incubation. The specific activity of 2',3'-cyclic nucleotide 3'-phosphohydrolase (CNPase) was diminished in the whole brain of animals born from treated eggs, as compared with controls.
