Data on morphological parameters of chickens eggs from a cross breed “Cobb-500” at 60 weeks of age, found that  increasing the mass hatching eggs incubation heralded high results. The output of chicken eggs high weight (71-82 g) is higher by 0,68% compared to the control group. This demonstrates the feasibility of incubation of eggs weighing 71-82 grams provided by a durable poultry breeder. The quality of hatching eggs from hens 60 weeks old is fairly high fertility – 83,64-85,00% hatchability – 89,00-93,20% output – 75,45-77,95% on standard rates for the cross 86,5, 86,6 and 79,5% respectively. Compared with the recommendations on cross fertility it is lower in -1,5-2,86% hatchability of eggs in groups at higher 2,4-6,6% output. For young a relatively lower standard at 1,55-2,23%. It is therefore advisable to use eggs of cross bred hen’s meat after 60 weeks , but to conduct special monitoring of the herd and poultry egg incubation regimes. Thus the use for incubation of eggs weighing 61-82 grams derived from chicken parent stock for long-term use, should be supported by normative documents on the incubation of eggs, including those with a weight exceeding 70 g.

Key words: incubation, hatching quality of eggs, fertility, hatchability of eggs output young.

Influence of mass of eggs of hens of meat direction the productivity on their morphological and incubation qualities.
