Studies on chick embryo sex determination and manipulation in the countries of the former USSR — a review. 2. Shifting of sex ratio
Romanov, Michael N. (Creator), Narushin, Valeriy G. (Creator), Sakhatsky, N I (Creator)
A review of some trials in the former USSR, attempting to influence the sex ratio in fowls by administering feed additives to hens, changing egg incubation temperature, treating eggs with amino acids and inducing parthenogenesis. The results of studies carried out in the countries of the former USSR on the problem of sex ratio shifting are reviewed with reference to impacts both on the parent organisms and on the embryos. The first way of shifting has been realized by using some additions to the hen rations and the second one by changing temperature, treating eggs with amino acids or orienting them in the Earth’s magnetic field during incubation. Also, the studies on manipulating poultry sex by the induced parthenogenesis are listed. [For Pt. 1 see pp. 320-321 of the Proceedings]
