Abstract

In the Dwarf three-colour breed and the Wyandotte dwarf white breed hens repeated inbreeding was performed.

The length of life, the growth, the body development, the feather growth, the laying performance and the hatchability of eggs of the offspring resulting from the inbreeding were within the standards of the breeds under study. In final generations of both breeds there was an increase in laying performance in comparison with the parent generation. In the Dwarf three-colour breed the respective figure was 21.7%/I 17.8 - 28.5/ and in Wyandotte dwarf white this was 28.6 % 120.9 - 39.2/. In both breeds there was a prolongation of the laying period which included late autumn and early spring
