Короткий опис(реферат):
Egg crosses are hens whose main purpose is to lay eggs. Breeders have done a lot of work,
which has resulted in highly productive species capable of laying up to 320-330 eggs in the first
year of life.
It has been scientifically proven that cross females are more hardy, better adapted and have
higher productivity. However, such efficiency is observed only in the first generation.
The right choice of laying hen crosses is a guarantee of high productivity.
