Summary Breed distribution of precipitin reactants (of types A and B) was encountered in: Brahma and Columbian Plymouth Rock ‐ high strength and frequencies; White Cornish, Dark Cornish, Minorca, Barred Plymouth Rock, New Hampshire, Rhode Island Red, Catalana and Cubalaya ‐ low to medium strength and frequencies; Australorp, White Leghorn, Polish, Sexline ‐ no reactions. Cocks exhibited only type A reactants. Both A and B substances were detected in egg yolks. Type A substances were encountered in sera of newly hatched chicks. Their decay was slow ‐ the mean persistence time being about 15 days. Only two young chicks among 160 tested exhibited the reactants of type B. Hormonal treatments of White Leghorn and Rhode Island Red cocks with testosterone propionate, progesterone, oestradiol benzoate or oestradiol benzoate along with progesterone failed to induce the synthesis of precipitin reactants.
