Area of Science:

  • Agricultural Science
  • Animal Science
  • Biotechnology

Background:

  • Hatching rate is crucial for poultry production and is influenced by egg physical characteristics.
  • Previous research indicates a correlation between egg parameters and hatchability, but precise modeling remains a challenge.

Purpose of the Study:

  • To model the relationship between key egg physical characteristics and hatching rate using Fuzzy logic.
  • To compare the predictive performance of Fuzzy logic modeling against multiple linear regression.

Main Methods:

  • Physical parameters including egg weight, eggshell thickness, sphericity, and yolk-to-albumen ratio were analyzed.
  • Fuzzy logic modeling with trapezoidal membership functions was developed based on commercial hatchery data.
  • Multiple linear regression was employed for comparative statistical analysis.

Main Results:

  • Fuzzy logic modeling demonstrated a higher coefficient of determination and lower mean square error compared to multiple linear regression.
  • Predicted hatchability rates from the Fuzzy logic model showed strong agreement with observed hatching rates.
  • The study validated Fuzzy logic as a robust tool for predicting hatching success.

Conclusions:

  • Fuzzy logic provides a superior method for modeling and predicting poultry hatching rates based on egg physical properties.
  • This advanced modeling technique can enhance hatchery efficiency and optimize poultry production outcomes.
