Fuzzy modeling to predict chicken egg hatchability in commercial hatchery

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.
