Factors Influencing Fertility and Hatchability of Poultry

Abstract

Poultry production at all scales of operation is wholly dependent on the supply of day-old chicks. Two important factors that have a significant impact on the supply of day-old chicks are fertility and hatchability. Hatchability is the proportion of fertile eggs that actually hatch, whereas fertility refers to the proportion of fertile eggs that are incubated. Understanding the elements that affect the fertility and hatchability of eggs is important. Breeds, diet, age of the hens, environmental stress, egg weight, shell thickness, porosity, and form index are the most important variables that affect fertility and hatchability. The internal and exterior egg characteristics are diminished by heat stress. Heat illness has an impact on all stages of the breeder's semen production. The fertility and hatchability of eggs are impacted by various facilities, including storage crates, hatcheries, and incubators. As a result, offering the best management and developing intervention strategies for improvement can increase poultry fertility and hatchability.
