Point down setting

Gentle egg handling, unique point down setting and accurate grading for hatchery automation.

The importance

Point down setting matters. The incidence of eggs set upside-down is largely dictated by human error and not by the shape of the eggs. To increase the hatchability it is important to set the points of the eggs down with a high accuracy.

In practice

The Prinzen egg setting machines are world renowned for their unsurpassed points down setting of 99.7%. An accurate point down setting of hatching eggs onto setter tray improves hatchability. Watch the video to see how it works in practice.

In-ovo vaccination

Especially when in-ovo vaccination is applied, additional improvements can be made by not losing potential chicks through killing of a wrongly positioned embryo.

Egg placing

When eggs are placed with the air cell down and the small end up, the embryo still turns. When the head is positioned in the small end of the egg - away from the air cell - it may die because the initiation of normal lung breathing is hampered or even blocked.

In normal development, from day 14, the embryo turns its position to the air cell. In this position, from day 18, the embryo can penetrate the inner cell membrane to gain access to the air in the air cell - after which breathing starts.
