Towards a more humane poultry farming: The transformative role of in ovo sexing.

The poultry sector, one of the largest food industries in the world, has long faced an ethical challenge: the culling of millions of newly hatched male chicks, as they are not profitable for meat or egg production. However, innovation and science have joined forces to change this reality through the in ovo sexing technique. This technique allows for determining the sex of a bird embryo within the egg, before it hatches.

Why is in ovo sexing important?

In ovo sexing has the potential to eradicate the controversial practice of culling, that is, the mass slaughter of male chicks. With this technique, eggs containing male embryos can be identified and redirected for other uses before they hatch, eliminating the need to cull live chicks.

In ovo sexing techniques:

Raman Spectroscopy:

Principle: A laser is directed at the egg, and the scattering of the reflected light is analyzed to determine the chemical composition inside the egg.

Advantages: It is a non-invasive technique and can be quite accurate.

Challenges: It can be expensive and requires proper calibration to ensure accuracy.

Infrared Spectroscopy:

Principle: Infrared light is used to analyze differences in egg absorption based on their composition, which helps determine the sex of the embryo.

Advantages: Similar to Raman spectroscopy, it is non-invasive.

Challenges: Like Raman, it requires specialized equipment and calibration.

Molecular Markers:

Principle: Small samples of the egg are analyzed for genetic markers indicating the sex of the embryo.

Advantages: Highly accurate.

Challenges: It is invasive and may require more time compared to other techniques.

Hormonal Differences:

Principle: Differences in the concentration of specific hormones between male and female embryos are sought.

Advantages: It may be less invasive than molecular markers.

Challenges: Accuracy can be affected by external factors and embryo development.

Magnetic Resonance Imaging (MRI):

Principle: MRI is used to visualize the inside of the egg and determine embryo characteristics.

Advantages: Non-invasive, provides a clear image of the embryo, and shows potential to be adapted to broader systems in the poultry industry.

Challenges: Traditionally, MRI has been a costly technique, raising questions about its practicality for mass use. However, innovation in tools like Genus Focus suggests there may be ways to overcome these obstacles in the industry.

In ovo sexing represents a monumental step towards more ethical and sustainable poultry farming. As these techniques are refined and become more accessible, the poultry industry is likely to experience a significant transformation in its practices, favoring not only animal welfare but also the efficiency and sustainability of production. With ongoing research and development, the future of in ovo sexing promises to be bright and revolutionary for the sector.”
