Optimising calcium and phytase levels to enhance eggshell quality

  • Publication
  • Organisation The University of Sydney
  • Researchers Dr Mehdi Toghyani

This project focuses on improving eggshell quality and laying performance in Australian layer hens by fine tuning calcium and phytase nutrition during the pullet and late-lay phases. It will combine controlled research trials with largescale commercial validation to generate practical, industry relevant data.The outcomes are expected to support bird welfare, reduce feed costs, and extend the productive lifespan of hens.

Results will be translated into clear nutritional guidelines for commercial use, enabling layer nutritionists to implement more sustainable and cost-effective feeding strategies without altering routine management practices. The project is industry-driven and designed for seamless adoption across diverse production systems.
