We Feed the Gut First
For Healthier, Heavier Calves, lambs and goat kids
Tonisity Rum-Xm is a highly palatable supplement developed by leading veterinarians to be easily incorporated into any feeding routine.
Mixed directly into fresh milk or milk replacer, it delivers targeted support to the gut at a cellular level, helping young ruminants absorb nutrients more efficiently.
The result is stronger, healthier animals that grow faster, perform better and reach their lifetime potential sooner.
Poor intestinal development costs more than you think.
When young ruminants struggle to absorb nutrients efficiently, the effects ripple through their future performance:
slower growth
delayed weaning
weaker immunity
lifetime productivity
Across any production system, every extra day to reach target weight means higher costs, more labour and lost potential.
That’s why Rum-Xm is ideal for:
-
Farmers looking to raise healthier, stronger youngstock
-
Veterinarians aiming to improve outcomes in early-life nutrition
-
Units dealing with scour issues, digestive stress or poor weight gain
-
Operations seeking more reliable pre-weaning performance
Whether you manage calves, lambs or goat kids, Rum-Xm provides a practical, science-backed solution to improve results from the very first milk feeding.
