Hatchability is important not only for planning and producing saleable day-old chicks but also for the quality of chicks and their growth and development throughout their lifecycle. The ability of a fertilized egg to develop into a viable chick depends on many factors. Temperature, humidity, airflow, biosecurity, and time are important components for ideal hatching. Another factor that plays a role in hatchability success is optimum nutrition, it is vital to overall health and should be safeguarded to ensure hatchability rates.
The nutritional status of parent stock is imperative for optimal growth and development of offspring. Nutrients are transferred from hen to egg, therefore optimum intake is critical. Inadequate levels of nutrients can cause a decrease in hatchability (Wilson 1997). The requirements of the chick can be met by adequately supplementing the hen to ensure proper levels of macro and micronutrients are deposited into the yolk (the chicks food source).
Vitamins and minerals interact in numerous ways, meaning the proper balance of nutrients are important but also complicated. For example, vitamin A, vitamin D, copper, zinc and magnesium interact closely. if one of these micronutrients is unbalanced it could impact the absorption and utilization of another. Supplementing birds with suitable micronutrient levels will have an impact on their performance, growth, development, health, and hatchability.
