Field Trial Confirms the Benefits of Pidolin® PCa in Breeder Hens

As breeder hens age, maintaining egg production, shell quality, and flock vitality becomes increasingly challenging. A recent large-scale field trial in the Czech Republic (2025) demonstrates how Pidolin® PCa (calcium pidolate) helps support laying persistence, egg quality, survivability and overall profitability in late-production breeder flocks.

Real Farm Conditions, Real Results

The 49-day trial was conducted under commercial conditions, involving nearly 40.000 breeder hens:

• Control group: Isa Brown, basal diet
• Pidolin® PCa group: Bovans Brown, basal diet + 300 g/t Pidolin® PCa
• Supplementation period: weeks 64–68

All management parameters (housing, temperature, lighting, density) were identical, ensuring supplementation was the key differentiating factor.

Improved Laying Persistence and Egg Output

Despite the advanced age of the flock, hens receiving Pidolin® PCa showed a clear performance advantage:

• +1.2 points laying persistence compared to the control
• +1.5% more eggs selected for incubation
• More stable production with lower variation over time

These results indicate that Pidolin® PCa helps sustain productive performance when natural calcium utilization typically declines.

Beyond productivity, flock health also benefited from supplementation:

• −0.19 percentage points lower mortality during the supplementation period

This reduction reflects improved physiological resilience in aging breeder hens.

Why Pidolin® PCa Works?

Pidolin® PCa combines calcium with pidolic acid, a biologically active molecule that:

• Promotes active calcium transport via arginine supply
• Supports collagen synthesis via proline supply
• Contributes to improved eggshell formation and structural integrity

The trial confirms that these mechanisms translate into measurable on-farm benefits.

Strong Economic Return

Performance gains were accompanied by an excellent financial outcome:

• Net benefit: €0,23 per hen
• ROI: 9:1
• Equivalent to €232 net benefit per 1.000 hens

Even after accounting for the supplementation cost, increased chick output drove a clear return on investment.

Proven Support for Aging Breeder Flocks

Pidolin® PCa is a practical nutritional tool to help breeders stay productive, profitable, and resilient in late lay.

Jadis has launched Fulvi Plus, a new concept for calves, extensively tested in practice, with feedback indicating that calves were more robust and healthier opening up for reduction of antimicrobials. 

Supporting the calves during the Immunity gap yield in better health, growth and future milk production  

Calves are susceptible to diseases and problems due to underdeveloped immunity and stress factors during the famous immunity gap of calves. They often experience issues with protozoa, bacteria, and viruses in the first weeks of life. These issues lead to: 

• Reduced intestinal health and inflammation, 

• Diarrhea and reduced growth, 

• Lower future production capacity. 

To address these challenges and reduce the need for antibiotics, Jadis Additiva developed Fulvi Plus for optimal support during this sensitive period. 

Key Benefits and Composition Supporting Intestinal Health and Improving Growth 

Fulvi Plus is a unique blend of phytogens specially developed to support the intestinal health of young calves. 

• Key Components: The base primarily contains clean and highly soluble fulvic acids and a small amount of humic acids, originating from humus (extracted from human drinking water). Those are known to improve intestinal health and gut integrity. 

• Enrichment: It is enriched with carefully selected aromatic and plant-based active ingredients, such as Yucca Shidigera, each with a unique effect in the intestines. They have been selected for known anti-protozal effect, binding ammonia, and improved digestion. 

Trial Results Highlights 

In vitro trials were conducted in 2019, confirming the expected successful mode of action. In 2023, a first field trial showed us improvement in growth. And now after successful start of Fulvi Plus for the first users, a trial in 2025 at a large dairy farm in the Netherlands confirm again the benefits. The results showed great potential for Fulvi Plus in supporting intestinal health and improving growth performance. 

• Trial Size: 106 calves were split into a control group (58 calves) and a Fulvi Plus group (48 calves). 

• Method: The trial group received 10 ml of Fulvi Plus mixed into their morning milk daily for the first 14 days and performance was measure after 14 days 

• Result:  

• Growth in the Fulvi Plus group improved significantly by 58 grams/calf/day. 

• • The Fulvi Plus Group have shown fewer occurrences of diarrhea   

 Availability 

Fulvi Plus is available as a liquid product, allowing it to be added directly to milk preparation for the calves.

Feed particle size has a direct impact on both animal health and farm profitability. While fine grinding improves nutrient availability, it can also increase the risk of stomach ulcers and reduce gut health in pigs. Finding the right balance between nutrient utilization and gastrointestinal integrity has long been a challenge for feed producers—until now.

Developed by Vestjyllands Andel, the VA SizeMatters system introduces a new era of precision and reliability in feed production. The patented sieving technology enables continuous, automated monitoring of feed particle size directly in the production line. Instead of relying on manual sieve tests performed every few days or batches, producers now gain real-time insight into every single mix.

This innovation allows immediate adjustments whenever particles are too coarse or too fine, preventing costly variations before they reach the animals. As a result, feed consistency, gut health, and production efficiency are all significantly improved.

“Stable particle size is crucial for herd efficiency and directly impacts the producer’s bottom line,” says Brian Agerbo, Sales Manager at Vestjyllands Andel. “VA SizeMatters allows us to guarantee the quality of every batch — not just in theory, but in practice.”

Field trials confirm the benefits. Data from continuous sampling show that early alerts enable feed mills to make corrections within just a few batches, ensuring feed remains within optimal parameters. This proactive approach replaces reactive quality control with a fully integrated management tool, turning precision feeding into a measurable standard.

With its combination of automation, accuracy, and animal welfare benefits, VA SizeMatters sets a new benchmark for modern feed production. By enabling real-time control, it helps producers safeguard pig health, optimize performance, and improve profitability — all while supporting more sustainable and responsible farming practices.
