The primary purpose of egg production in the poultry industry is to produce eggs for human consumption. Eggs are a valuable source of protein, vitamins, and minerals, and are a staple food in many cultures.

Chickens are the primary type of poultry used for egg production. They are known for their high egg-laying capacity and relatively short production cycle.

The average egg-laying cycle of a hen is approximately 24-26 weeks. During this period, a hen can lay up to 300 eggs.

Egg production in hens is influenced by a combination of factors, including breed and genetics, nutrition and diet, housing and management, and health and disease.

The White Leghorn breed of chicken is renowned for its high egg-laying capacity. They are known to lay up to 300 eggs per year.

The optimal temperature range for egg production in hens is between 20-25°C (68-77°F). Temperatures outside this range can negatively impact egg production.

Light plays a crucial role in egg production. Artificial lighting is used in poultry houses to stimulate egg production and maintain a consistent laying cycle.

The ideal protein level in the diet of laying hens is between 18-20%. This level ensures optimal egg production and egg quality.

Calcium is a crucial nutrient for laying hens as it is essential for eggshell formation. A diet deficient in calcium can lead to thin or weak eggshells.

Beak trimming is a common practice in egg production to prevent cannibalism among hens. It involves trimming the sharp tips of the beaks to reduce the risk of injury and feather pecking.

Infectious bronchitis is the most prevalent disease that affects egg production in hens. It is a highly contagious respiratory disease that can cause a significant drop in egg production.

The recommended vaccination schedule for egg-laying hens includes vaccination against Marek's disease, Newcastle disease, and infectious bronchitis. These diseases can have a significant impact on egg production and overall flock health.

The average lifespan of a laying hen in commercial egg production is typically between 12-18 months. After this period, their egg production declines, and they are usually replaced with younger hens.

Culling is the term used to describe the process of discarding older hens from the laying flock. This is done to maintain optimal egg production and flock health.

The quality of an egg is determined by a combination of factors, including eggshell thickness, yolk color, albumen height, and overall cleanliness.
