Hatching quality chicks - 1

Hatching quality chicks Embryos have different needs during the various phases of the incubation period. Pas Reform understands those needs and has designed incubators to the highest standards to provide optimal incubation conditions that maximise hatchability and chick uniformity. Incubators from Pas Reform promote the best chick quality, maximising growth and minimising feed conversion rates, which are essential for the profitability of poultry production.

Embryology Good hatchability is no accident. During incubation the embryo passes through three critical stages of development before it is able to hatch successfully. Each phase requires specific conditions for optimum incubation and at all times the eggs benefit from a uniform distribution of temperature, humidity and respiratory gases. Knowledge of the needs of the growing embryo Evaluation of chick quality Optimal chick quality and hatchability Detailed research on the interaction between embryo and incubator climate During phase 1 the embryo follows a sequence of complex morphological,...

Corridor The corridor in Pas Reform setters serves several important functions (see photo 5). First, it assists in the uniform flow of air around the eggs. Second, in combination with the small door in a Pas Reform setter, it allows inspection of the cabinet and systematic analysis of embryo temperature, without disturbing the internal climate of the setter. Third, it may also be used for temporary storage of setter trolleys when other incubators are being cleaned, undergoing maintenance, or when there is a peak in egg supply.

Temperature maintenance Cell metabolism generates heat as a waste product and so as the embryos grow they produce more and more heat. After the mid-point of incubation eggs begin to produce excess heat. Although some metabolic heat is lost through the evaporation of water vapour from the egg and the transfer of heat to the air in the incubator, a cooling system is needed to remove the excess heat. This ensures adequate cooling of the egg to achieve an optimal incubation temperature for the embryo. 13 PID (Proportional Integral Derivative) control Incubator ventilation As the embryos grow...

Temperature maintenance Hatching is an active process during which the embryo generates even more metabolic heat. To prevent heat stress during this time, controlling the air temperature is particularly critical. 16 Pas Reform hatchers are equipped with water-cooling pipes incorporated in the aluminium wall panels (see photo 14). This results in a massive increase in the surface area for cooling, which helps to maintain uniform temperature distribution. Easy to clean hatcher Pas Reform hatchers achieve optimal air distribution and ventilation capacity by using ventilation openings in the...
