We Feed the Gut First
For Stronger, 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 nutritional support designed to support nutrient uptake and early-life development.
The result is animals that support stronger growth performance and improved early-life development.
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 aiming to support feed intake, growth and early-life performance
-
Operations seeking more reliable pre-weaning performance
Whether you manage calves, lambs or goat kids, Rum-Xm provides a practical, science-backed solution to support early-life performance from the very first milk feeding.
