Abstract

In our region, high temperature indices
in poultry houses in the summer often cause heat
stress in the poultry, which leads to a decrease in feed
intake, growth rate, bird livability and egg quality.
Effects of heat stress can be mitigated by “training” of
embryos to the effects of high temperatures during
incubation. In connection with this, the goal of the
work was to determine the effect of the developed
regime of temperature stimulation of chick embryos
on the results of incubation, weight and the livability
of chickens. It has been established that the use of

temperature stimulation regime (developed at State
Research Poultry Station) during the embryogenesis,
positively influences the hatchability of eggs. So,
egg hatchability in the experimental group was
2.7% (P≤0.01) higher, than in the control group. The
tendency to a positive effect from the application
of the temperature stimulation of the birds during
embryogenesis on their livability and weight

when grown during the hot season of the year was
detected.
