The factor that seems to influence yolk utilization most is temperature. If the temperature is off, the development of the embryo is not optimal, and consequently the transition from yolk to embryo is not optimal, and more yolk is left over.
The question about maximum utilization of the yolk is actually a question if the birds needs a minimum amount of yolk as residual yolk for the first days ...

The best day of in-ovo injection actually depends on the development of the embryo.
If the embryo is too small, you inject into the allantois, which means the vaccin is not effective.
If the embryo is too big, you have a risk of injecting it in the breast, neck or head. That gives good vaccination, but of course bears a bigger risk for the embryo.
As the temperature profile determines ...

During incubation, the content of an egg is transformed into a living, day old chick. This miracle of life is the result of a very delicate process, that requires a high level of understanding and control for optimum results. Everybody in the (incubation) industry knows how sensitive these processes are and how subtle the changes in settings and conditions are that make the difference between good ...

The development of the embryo is determined by the temperature inside the shell, the embryo temperature. This temperature will dictate the development, but with that also the hatchability and the quality of the day-old chick.
It is often assumed that this temperature is fully dependent on the temperature of the air. Although air temperature has a large influence on it, it is not the only factor a ...
