OvoScan™
Scientific research and field tests prove OvoScan™ is a bio-response system that significantly improves hatchability and chick quality.
Maintaining the optimum incubation temperature is extremely critical in determining both hatching and post-hatch performance.
The temperature around the embryo depends upon three parameters:
1/ the temperature of the air surrounding the egg
2/ the heat transport between the egg and its environment
3/ the time-variable heat production of the embryo
As it has indeed long been agreed that the air temperature within an incubator is no more than a rough indication of what is actually going on inside the egg, Petersime decided to attack the heat exchange between the embryo and its environment as the third bio-response to control the incubator climate.
Because of its poikilothermic nature, the ambient temperature around the avian embryo is determining its metabolic rate, and thus the heat production of the embryo.
The actual heat transfer between embryo and environment however, is depending upon more than just ambient temperature of the incubating egg: eggshell conductance differing between breeds and flock ages (porosity, surface/volume ratio), humidity of the air surrounding the egg (better heat transportation in more humid air) and air velocity are major factors influencing heat flow.
Petersime decided to automise on-line temperature measurements on the barrier between embryo and environment – the eggshell – as a measure for heat exchange and developed OvoScan™. By actively controlling this temperature the incubator allows for adequate temperature control in accordance with the actual egg mass present in the machine. In other words: within preset boundaries of ambient climate, the machine electronics measure and correctively interact in order to maintain the desired eggshell temperature level and keep the embryo’s heat exchange in balance.
OvoScan™ is unique to Petersime and is available as an option on AirStreamer™ setters with the FOCUS™ controller.
Components:
The key component of the OvoScan™ system is the infra-red shell scanner. The shell scanner uses infra-red sensing to capture the exact temperature of four adjacent hatching eggs. While standard infra-red temperature sensors can't be used to measure surface temperatures close to the enviroment temperature, Ovoscan, developed and calibrated in cooperation with the University of Louvain, measures the eggshell temperature with undisputed accuracy.
