INTERRELATIONOF EMBRYONAL DEVELOPMENT OF CHICKENS WITH STORAGE TERMSOF INCUBATION EGGS

Abstract

The article presents the results of studies on the relationship between the embryonic development of chickens and the shelf life of hatching eggs. In the studies, the authors noted that with an increase in the shelf life of the hatching eggs, a decrease in the hatchability of day-old chickens is observed. If the interval between the demolition and the beginning of the incubation was 5 days,
the hatchability showed good results of 87.2%, 9 days - 6% lower than at the 5th day; if the interval between the demolition and the beginning of the incubation was long - 18 days, then the hatchability decreased 20.2% compared with 5 days storage. Also, with prolonged storage, an increase in incubation waste was noted, so at 18 days storage - 33%, which is 15% more than at 5 days egg storage. Thus, in order to reduce the loss of death of embryos, increase hatchability, obtain healthy young animals, and improve the embryonic development of chickens, it is proposed to store hatching eggs for a period of not more than 5 days.
