Non-Destructive Assessment of Chicken Egg Fertility

Area of Science:

• Agricultural Science
• Food Technology
• Biotechnology

Background:

• Over 1 billion hatching eggs were set in Canada in 2017, with an 82% fertility rate.
• This resulted in approximately 180 million unhatched eggs, valued at over 300 million Canadian dollars.
• Current methods like candling are inefficient, leading to substantial economic losses in the poultry industry.

Purpose of the Study:

• To review existing non-destructive technologies for early chicken egg fertility identification.
• To highlight the potential of emerging technologies for improving economic outcomes in egg production.
• To address the need for a fast, online prediction technology for non-fertile egg detection.

Main Methods:

• A comprehensive review of non-destructive techniques was conducted.
• Methods discussed include ultrasound, dielectric measurements, thermal imaging, machine vision, spectroscopy, and hyperspectral imaging.
• Hyperspectral imaging was identified as a promising emerging technology.

Main Results:

• Conventional candling is subjective, slow, and inefficient for fertility assessment.
• Various non-destructive techniques show potential for early detection of chicken egg fertility.
• Hyperspectral imaging offers significant promise as a futuristic solution.

Conclusions:

• There is a critical need for advanced, non-destructive technologies for early chicken egg fertility identification.
• Hyperspectral imaging presents a strong potential for developing robust models for this purpose.
• Implementing such technologies can mitigate economic losses and optimize resource utilization in the poultry sector.
