When moving eggs from storage to the incubator, the eggshell temperature needs to be raised to 37.8°C – the optimal temperature for the start of the incubation process. The time it takes to raise the temperature often depends on planning issues, such as when the eggs arrive and whether the setter is clean and available. Too often, when pressed for time, the setter is “quick started”, which warms the eggs as fast as possible, in order to prevent the chicks later hatching too late.
HatchTech Research has shown that the fast warming process negatively affects hatchability and chick quality. They found that the part of the warming process in which the temperature increases between 29°C and 37.8°C is particularly crucial. A slow warming period (between 12 and 18 hours) for this phase improves hatchability and chick quality in short- and long-stored eggs.
Dosed disinfection, better results
Traditional disinfection
Traditional disinfection
During traditional disinfection, a disinfectant container is pushed into the hatcher. The disinfectant then evaporates.
Disadvantages of traditional disinfection include:
The amount of evaporation can be reduced due to precipitating dust.
The rate at which evaporation occurs is not measured or monitored.
There is a risk that the disinfectant will completely evaporate before hatching starts (which is when disinfection is needed the most).
The concentration of disinfectant decreases just as the bacteria pressure increases.
There is an unnecessarily high concentration of disinfectant during embryo development, which can have adverse effects on animal welfare.
HatchTech Spray System
HatchTech Spray System
The HatchTech Spray System is a disinfection system that distributes disinfectant into the air in a pulsatile manner. For more information about the HatchTech Spray System contact: service@hatchtech.nl
Advantages of the HatchTech Spray System (compared to the conventional disinfection method) include:
The distribution of disinfectant is dosed.
The disinfectant is disseminated at fixed intervals, which can be adjusted as desired.
The bacterial pressure is kept at a consistently low level, which is particularly important when chicks leave their shells.
There is less disinfectant present during embryo development, which is better for animal welfare.
