What do you mean by Hatchability and Livability percentages? Explain how it will be useful in evaluating the performance of a hatchery.

Hatchability and livability percentages are key performance indicators used in evaluating the performance of a hatchery in the poultry industry.

Hatchability Percentage: Hatchability refers to the percentage of fertile eggs that successfully hatch into healthy chicks. It is calculated by dividing the number of chicks hatched by the total number of fertile eggs set in the incubator, multiplied by 100. A high hatchability percentage indicates effective incubation practices, optimal environmental conditions, and good egg quality.

Livability Percentage: Livability, also known as chick survival rate, refers to the percentage of hatched chicks that survive and thrive after hatching. It is calculated by dividing the number of surviving chicks at a certain age (usually 7 or 14 days) by the total number of chicks hatched, multiplied by 100. A high livability percentage indicates effective brooding, adequate nutrition, and proper management practices post-hatch.

Evaluating hatchability and livability percentages is crucial for assessing the overall performance and efficiency of a hatchery. High hatchability percentages indicate the hatchery's ability to maintain optimal conditions during incubation, handle eggs carefully, and ensure proper ventilation, humidity, and turning. High livability percentages reflect the hatchery's success in providing optimal conditions for chick growth, including appropriate temperature, nutrition, sanitation, and disease management.

By monitoring hatchability and livability percentages over time, hatchery managers can identify areas for improvement, implement corrective measures, and optimize hatchery operations to enhance productivity, profitability, and customer satisfaction. Additionally, these metrics provide valuable feedback to breeders, farmers, and suppliers regarding the quality and viability of chicks produced by the hatchery.
