Abstract. The study demonstrated the effect of polyamine – putrescine on the hatchability of diurnal young animals when injected into fertilized chicken eggs under microclimatic stress caused by both a decrease (cold microclimatic stress) and an increase in temperature (thermal microclimatic stress) during incubation. When putrescine was administered on the 6th day of incubation under cold microclimatic stress, an increase in hatchability of young chickens was observed by 2-3% on the first day compared with the «Cold stress» group, which is characterized by a decrease in hatchability and survival of chickens. When exposed to heat stress, the hatchability of chickens increased with the introduction of putrescine during incubation by 1-4% compared with the group whose chickens were under thermal microclimatic stress. The results confirm the importance of polyamines in regulating the formation of ontogenesis and increasing the hatchability of healthy chickens. The research opens up prospects for the development of new ways to intensify poultry farming under conditions of microclimatic stress.
Keywords: polyamines, putrescine, incubation, microclimatic stress, poultry farming, hatching eggs, chickens, zootechnical parameters, exterior, hatchability, preservation.
