The influence of the age of the parent herds and the duration of incubation egg storage on the development of embryos and the quality of the daily broiler

Abstract

he article says that the development of domestic industrial poultry farming at this stage involves the introduction of advanced technologies at different stages of the production cycle, starting from the incubation egg to the production of a full-fledged viable day-old chicken. The article presents data on changes in the quality indicators of incubation eggs after excessive, long-term storage before the incubation process, analyzes the causes of embryo death at different stages of development, determines the quality of a day-old chicken, its safety up to 10 days of age and the state of the immune system before the cycle of routine vaccinations of the broiler herd. As a result of the analysis of embryonic development, it was found that long-term storage of eggs, especially from young flocks and herds ending their productive period, negatively affects the growth and development of embryos, which leads to increased embryo waste during incubation, prolonged withdrawal of young and negative
