Effect of Reserpine on Rate of Mortality and Growth of Duck Embryos

ADAMS et al. 1 , who injected varying doses of reserpine into the yolks of eggs of White Plymouth Rock hens during the first week of incubation, reported that in the embryos treated the mortality rate increased with increasing dosage, and that the average body-weight of the surviving embryos was lower than that of the controls. On the other hand, van Limborgh et al. 2 were unable to demonstrate a similar influence on the mortality rate in one-day Khaki Campbell duck embryos. Uchida 3 observed a rise of the mortality-rate with increasing dosage but no significant changes in the body-weight in eighteen-day-old White Leghorn egg embryos.
