Untersuchungen zur Ermittlung toxischer Wirkungen von Derivaten der 2,4-Dichlor- und 2,4,5-Trichlorphenoxyessigsäure (2,4-D und 2,4,5-T) auf Bruteier von Fasanen,Wachteln und Hühnern

Studies on the susceptibility of eggs of gallinaceous birds to 2,4,5-T and 2,4-D. First reportStudies were performed on a total of 3,693 eggs from Japanese quails, 1,080 eggs from pheasants and 500 hen's eggs to investigate the possible effect of 2,4-D or a mixture of 2,4-D and 2,4,5-T on the hatching rate, body weight and malformations of offsprings.Non-incubated and preincubated (3 days) eggs were sprayed with up to 10 times the amount of herbicides normaley used. The eggs serving as controls were treated with tap water.As compared with the controls, the herbicides did not affect hatching rate, body weight or the number of malformations.
