Tonisity Px at Weaning | Improve Piglet Feed Intake, Gut Health & Growth

Tonisity Px is a highly palatable, isotonic protein solution supplying essential nutrients to the piglet gut from day 2 of life.
It is formulated to nourish enterocytes directly  the intestinal cells responsible for nutrient absorption.

Unlike simple electrolytes, Tonisity Px does more than hydrate.
It is a patented micro-enteral nutrition technology that prepares the gut to function more efficiently during the most sensitive stages of early life.

Why Use Tonisity Px at Weaning?

Weaning is one of the most critical phases in a piglet’s life.
Reduced intake, intestinal damage and growth check frequently occur within the first 24–72 hours, setting pigs back for the entire nursery and finishing period.

The Tonisity Px Weaning Protocol was designed to proactively manage this transition before damage occurs, protecting intake, gut integrity and growth when it matters most.

The Tonisity Px Protocols

Different Tonisity Px protocols serve different objectives and farm realities. Three options are recommended depending on the challenge faced:

• Early life (Day 2-8 – Tonisity Px 3% liquid):
  Designed primarily to support piglet survival and reduce mortality, particularly in challenging systems. 
• At creep feed introduction (Day ~10–12 or at creep feed introduction; Tonisity Px 3% liquid + feed):
  Designed to stimulate early feed exploration and intake before weaning. 
• Peri-weaning (3 days pre- and 3 days post-weaning; Tonisity Px 3% solution on feed):
  The key driver of feed intake and growth performance through the weaning transition.

How Tonisity Px Works at Weaning

At weaning, Tonisity Px acts by

Protecting Gut Integrity: Feeding the enterocytes directly to prevent the villus shortening and “leaky gut” associated with undernutrition.

Stimulating Feed Intake: Bridging the “hunger gap” to ensure piglets approach and consume solid feed sooner post-weaning.

Sustaining Growth: Reducing the severity of the post-weaning growth check to ensure more piglets meet their performance targets.

The Tonisity Px Weaning Protocol

Simple. Practical. Repeatable.

Designed for farms with limited labour or high staff turnover, the Tonisity Px weaning programme is easy to implement, consistent and effective, from small farms to large integrated systems.

How to Prepare Tonisity Px (One Simple Rule)

👉 Always prepare it the same way:

✅ 1 full pink scoop (15 g) per 500 ml of water (enough for 1 litter for 1 day)
OR

✅ 2 full white scoops (310 g total) per 10 litres of water (enough for 20 litters for 1 day)

Mixing and Administration Tips

Add water first, then Tonisity Px powder

Mix until fully dissolved

Use immediately after preparation

Pour liquid on top of feed peri-weaning

Prepare fresh daily

💡 The mixture appears white/milky — this is normal and highly palatable for piglets.

Before Weaning (3 Days) — D-3 | D-2 | D-1

What to do:

Prepare Tonisity Px

Offer 500 ml per litter

Pour directly on top of creep feed

After Weaning (3 Days) — D+1 | D+2 | D+3

What to do:

Prepare Tonisity Px

Offer up to 100 ml per piglet, always on feed

The Post-Weaning Protocol – Specific Instructions 

*These recommendations are assuming Tonisity Px can only be given strictly post-weaning. For best results, discuss pre-weaning protocols with your Tonisity Technical Representative

Feed intake 30–40% higher in the three days pre-weaning

86% vs 77% of piglets achieved positive ADG in the first week post-weaning

Study 24-010-P-P (Spain – 200 pigs)

4.2× higher feed intake in the first two hours post-weaning

Study 16-002-P-R (Spain – 150 pigs)

Feed intake 2.1× higher (+192 g/pig) in the first five days post-weaning

2.6× more piglets achieved positive ADG in the first week

Study 25-064-P-P

89% of Tonisity Px piglets achieved positive ADG in week one vs 75% in controls

Study 18-126-P-P

+200 g extra weaning weight and +300 g extra nursery weight (2 weeks post-weaning)

65% less E. coli after 1 week in nursery

+34% taller villi after 1 week in nursery

Long-Term Performance and Nursery Mortality

Study 23-031-P-P (Belgium – 481 pigs)

+1.92 kg (+8%) higher weight at end of nursery (p < 0.001)

35% reduction in nursery mortality

Protocols for “Fall-Behind” Piglets

Field observations

Study 23-001-P-P (Vietnam – 20 pigs)

Mortality reduced from 5% to 0%

+17% increase in average weight (+1,070 g)

Visible health improvements within three days (shinier hair, less diarrhoea)

Study 22-069-P-P (Vietnam – 200 pigs)

+3.8% improvement in weight at 3 weeks in nursery

15.7% better FCR (1.44 vs 1.71 control)

Visual improvements: brighter eyes, shinier skin, increased agility

In Summary

Using Tonisity Px at weaning delivers:

✔ Earlier intake
✔ Better gut integrity
✔ Reduced growth check
✔ Lower mortality
✔ Stronger return on investment

Support the gut before stress, not after damage
