Egg Production Lecture

Integrated Egg Production Mechanization

  • Full mechanization and automation of egg production includes:

    • Conveyor systems

    • Mechanized processes

    • Integration into an "egg train"

Chicken Egg Sizes

  • Egg sizes categorized as:

    • Peewee: 10 ounces

    • Small: 18 ounces

    • Medium: 21 ounces

    • Large: 24 ounces

    • XL (Extra Large): 27 ounces

    • Jumbo: More than 30 ounces

  • Understanding these sizes is essential for proper classification in egg production.

Factors Affecting Egg Production

  1. Breed:

    • Significant influence on egg laying capabilities.

    • Examples of laying breeds:

      • ISECs

      • COM

      • Public COM

      • Vantress

  2. Management and Feeding Practices:

    • Key determinants for optimal egg production.

  3. Mortality Rate:

    • Natural occurrence of mortality among large flocks.

    • Influencing causes include disease, predation, and environmental stress.

    • Specific mortality rates:

      • Chicks: 4%

      • Growers: 15%

      • Layers: 12%

    • Average annual mortality should fall between 20-25%.

  4. Age of Birds:

    • Egg production begins around the 20th to 21st week and lasts over a year.

    • Optimal weight for egg production is around 1.5 kilograms.

  5. Environmental Factors:

    • Proper building design according to climate can improve production.

    • Need for regulated daylight and artificial lighting to stimulate egg production.

Lighting and Egg Production

  • Egg production is stimulated by exposure to light.

    • Recommended light exposure:

      • Artificial light for 2-3 extra hours can increase egg production by 20-30%.

Feeding Strategies

  • Free-range hens versus hybrids:

    • Hybrids typically produce more meat and eggs with supplemental feeding.

  • Access to fresh, clean water is critical for optimal production.

Culling Practices

  • Culling is necessary to remove unproductive or sick birds.

    • Methods of culling:

      • Mass Culling: Entire flock removal

      • Regular checks to prevent waste and improve productivity.

Egg Production Cycle

  • Cycle stages:

    1. Chicks/Brooders: 0-2 months

    2. Growers: Lasts 3 months

    3. Layers: Start laying after 21 weeks

  • Typical production cycle lasts 17 months (or 74 weeks).

Production Planning

  • Importance of having multiple age groups for consistent production.

    • Suggested batches: 2-3 for optimal operational efficiency.

Financial Considerations

  • Profit determined by sales minus operational costs.

  • Categories of costs:

    • Fixed Costs: 5-10% of total costs

    • Variable Costs and Expenses: Depreciation, animal health care, feeding.

Fertility Testing of Eggs

  • White eggs fertility test: 3rd day; brown eggs: 5th or 6th day.

  • Importance of collecting eggs frequently to monitor fertility and prevent damage.

Molting and Egg Production

  • Chickens naturally molt, losing feathers and replenishing them over 8-12 weeks.

  • Molting can affect egg production, but nutrition can help shorten the duration.
