    Area of Science:

    • Animal Science
    • Agricultural Engineering
    • Quantitative Biology

    Background:

    • Laying hen productivity is influenced by numerous environmental and nutritional factors.
    • Optimizing feed intake and egg output is crucial for economic viability in poultry farming.
    • Existing models may not fully integrate diverse variables or financial outcomes.

    Purpose of the Study:

    • To develop an empirical simulation model for predicting laying hen food intake and egg output.
    • To assess the financial implications of various management and environmental conditions.
    • To provide a tool for examining the effects of management changes during the laying period.

    Main Methods:

    • Quantitative literature review to establish a data foundation.
    • Development of an empirical simulation model incorporating temperature, light, nutrition, and feeding systems.
