A Stronger Defense is a Better Offense

Bovine Respiratory Disease costs the beef industry $1 Billion every year! 

BRD is an upper and lower respiratory disease that includes common respiratory illnesses like shipping fever and pneumonia.  During weaning, calves are hit with a plethora of stressors including: processing, environment, diet changes and transportation.  These stressors affect calves’ immune systems and lowers their ability to fight back against diseases.  Therefore, Purina introduced a new product: RX3 Immune Support Technology!  The 3 R’s Recognize, Respond and Return to health, gives the calves the boost they need, and “Sets calves up for a healthy Start."

RX3 helps calves aid in fighting against respiratory challenges, using a precise combination of prebiotics, probiotics and plant extracts.   Its non-medicated, therefore, a VFD is not required, although it will still be available with medicated products based on the producer’s preferences.  RX3 will be available in all starting programs including Accuration, Precon, and the Stress Care lines.  Research shows that calves fed RX3 have less average daily gain variation and within a 30-day period gained on average 6 pounds more then the control group. 

The way it works: RX3 primes the calves immune system to support overall calf health, which in turn reduces cots and sets calves up for a healthy start. It allows calves to Recognize disease sooner, using an immune system that is primed and can recognize pathogens.  Calves are then able to Respond by using a healthy immune system to eliminate pathogens and Return to health with faster recovery and healthier looking calves.
