Pidolin PCa: Study on the effect of Pidolin PCa on eggs quality at the end of the laying cycle in long-career laying hens

In 2025, Dietaxion led a trial in a laying hens farm in Tunisia to demonstrate the benefits of using Pidolin PCa in the context of long-term production (over 87 weeks of age).
Our objective? Demonstrate the interest of supplementing with Pidolin PCa at the end of the laying period, especially in the context of longer career times.

The egg production sector aims to extend the productive lifespan of hens to boost farm profitability and reduce the agricultural sector’s carbon footprint. However, this goal faces an obstacle: eggshell quality and laying rate decrease as flocks age.

In this trial led by Dietaxion and a partner, hens were supplemented with 300 grams of Pidolin PCa per ton of feed starting at week 87 of age. The parameters studied are eggshell resistance, the rate of downgraded eggs, and egg candling.

Pidolin PCa at the end of laying rate to maintain a profitable laying rate

The results of the first trial confirm the effectiveness of Pidolin PCa in maintaining the laying rate. The analysis of the number of eggs produced during the two weeks before supplementation showed that the hens initially had a laying rate below the genetic standard. Incorporating Pidolin PCa into the feed significantly improved this parameter. Dietaxion nutritional solution optimized the laying rate, exceeding the expected reference values and demonstrating the product’s ability to increase profitability at the end of the production cycle.

While improving or maintaining egg-laying rates is a major challenge, this should not be achieved at the expense of shell quality. The trial results show that, while maintaining a laying rate above genetic standards, shell strength is increased by 26% (measured in Newtons on a sample of 30 eggs). Additionally, the proportion of opaque eggs (an indicator of optimal quality) has increased by 63 points.

In conclusion, Pidolin PCa supplementation enabled farmers to increase their sales of category A and downgraded eggs at the end of the batch, despite the restrictive context associated with the advanced age of the laying hens. The supplementation became profitable from the fourth week of use, and the gains increased with continued use. Therefore, it is important to initiate the treatment as soon as a drop in the laying rate or an excessive increase in downgraded eggs is observed.
