In an average egg shell temperature between days 5 and 10, Line represents an incubator temperature program resulting Incubator set point (lines) in a commercial incubator. Shell temperature (dotted lines: n=30 eggs) and the Summary of the relationship between average egg In figureġ, a typical incubation program for a broiler embryo isįigure 1. To prevent overheating the air surrounding the eggs mustīe cooled such that heat is removed from the eggs. The embryo grows, metabolic heat production increases and Temperature must be higher than the egg temperature. The temperature of the air at the level of the eggs, whichĭetermines the temperature of the egg and embryo.Īt the start of incubation the embryo produces little heatĪnd eggs must be warmed. Temperature set point at which the incubator operates and In the incubator we must differentiate between the Shows an increase towards the end of incubation. The natural pattern of the embryo and eggshell temperature Phases requires specific incubator conditions.Īs the embryo grows, its metabolic rate increases and this isĪccompanied by increased heat production. Occur in the later phases of development. The growth and the maturation of the organs Typically, differentiation of organs occurs in the first days of

Roughly be divided into three different phases: Marleen Boerjan, Embryologist, Pas Reform - The most critical factor in commercial incubation is the temperature that the developing embryo experiences.Įmbryonic development is a continuous process that can Why Incubator Temperature Differs From Egg Shell Temperature - By Dr.
