[Comparative effects of intravitellin injections of p, p'-DDT and of commercial DDT on the germ cells of embryonic gonads of birds].

The p, p'-DDT present in the composition of commercial DDT, is responsible for the germ deficit in the gonads of bird embryos. Administered into the vitellus or on the shell, before incubation, the pesticide exerts the same reduction of the Quail germ population. While, for the Chick, the germ decrease is less significant after injection than after immersion.
