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 maximize hatchability and chick uniformity. Incubators from Pas Reform promote the best chick quatility, maximizing growth and minimizing feed conversion rates, which are essential for the profitability of poultry production.

Good hatchability is no accident. Nature has created a heat-dependent process that draws on maternal body temperature and the production of metabolic heat to produce healthy, first-class chicks. Nature has the answers, and our aim in the commercial hatchery must be to mimic these natural conditions as closely as possible, to produce very large numbers of healthy, first-class chicks that meet the ever-growing demands of commercial poultry markets around the world.

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 uniform distribution of temperature, ventilation and humidity.

During phase 1 the embryo follows a sequence of complex morphological, physiological and biochemical changes that take it from a single cell immediately after fertilization to an almost fully formed bird.

Phase 2 takes place in the second half of the incubation period. By the middle of incubation the embyo has about 95 percent of its bodily organs and so only needs to increase in size in readiness for hatching.

The first 2 phases occur in the setter, but the third and final phase occurs in the hatcher. During phase 3 the embryo undergoes a series of events that enable it to survive outside the protective environment of the shell.
