Tonisity has announced the publication of the largest global meta-analysis ever conducted on pre-weaning piglet performance, providing new insight into one of the most economically critical phases in pig production.

The dataset compiled from over 100 independent trials and more than 100,000 piglets across multiple production systems worldwide offers robust, field-validated evidence on how targeted neonatal nutrition can significantly reduce mortality, improve uniformity, and increase lifetime performance.

The findings arrive at a time when European pig producers face increasing pressure to improve efficiency, reduce losses, and maximise output per sow without adding labour complexity.

What Does the 2026 Meta-Analysis Show?

Tonisity’s global dataset provides one of the most comprehensive evidence bases available on neonatal pig nutrition.

Pre-Weaning Mortality: −21%

Across 133 studies involving 259,888 piglets, supplementation with Tonisity Px resulted in a 21% reduction in pre-weaning mortality.

In practical terms, this equates to approximately:

• +22 piglets saved per 1,000 born alive

Importantly, this effect was consistent across:

• Different geographic regions
• Varying weaning ages
• A wide range of birth weights

This consistency highlights that the results are not system-dependent, but broadly reproducible.

Fall-Behind Piglets: −36%

Based on 29 studies, the proportion of piglets falling below expected weaning thresholds was reduced by 36%.

This translates into:

• +72 additional full-value pigs per 1,000 born

The implications extend beyond numbers:

• Improved litter uniformity
• Reduced management complexity
• Lower health and antibiotic pressure
• Greater predictability across batches

Weaning Weight: +300 g | Finishing Weight: +2.5 kg

In 46 studies assessing growth performance:

• Piglets were +300 g heavier at weaning (+5%)
• This early advantage translated into +2.5 kg at finishing

This illustrates a well-recognised biological principle: early-life growth sets the trajectory for lifetime performance.

Even modest improvements in the first days can compound into measurable economic gains at slaughter.

Mode of Action: Supporting the Gut Where It Matters Most

Tonisity Px is formulated as an isotonic protein solution designed specifically for neonatal piglets.

Unlike conventional electrolyte solutions, its function is nutritional rather than purely rehydrating.

Key characteristics include:

• Voluntary intake from Day 2 of life
  Piglets consume it naturally without force-feeding or additional stress
• Direct support of intestinal development
  Nutrients are delivered to enterocytes, supporting gut structure and absorptive function
• Low labour requirement
  Administration takes less than 20 seconds per litter, with no disruption to routine

The concept is simple:
the piglet drinks, and the gut responds — quickly and locally.

What Does This Mean at Farm Level?

To illustrate the potential impact, consider a 500-sow unit:

• 14 live-born piglets per litter
• 2.4 litters per sow per year
• ≈16,800 piglets born annually

Applying the meta-analysis outcomes:

While absolute figures vary by system, the direction of impact is consistent:

more piglets, more uniform batches, and heavier animals at sale.

Conclusion: Performance Gains Start in the First 48 Hours

As margins tighten across European pig production, efficiency gains are increasingly dependent on precision management, particularly in early life.

Tonisity’s 2026 meta-analysis provides a strong, data-driven foundation showing that:

• Neonatal nutrition can significantly influence survival
• Early gut support improves uniformity and growth
• Small early gains compound into measurable finishing benefits

For many producers, the first two days of life represent an underutilised opportunity to improve whole-cycle performance.
