When to Use the Calf Program


A chart shows four calf supplements and their recommended use from birth through post-weaning, with color bars indicating timing and purpose: Start Strong, Stand Strong, Fight Strong Pellet, and Rapid Strike.

RESEARCH PROVEN


Ralco has conducted 17 research trials involving over 1,100 calves using this Ralco Calf Program.

Each study measured real-world performance over 56 days, tracking weight gain, starter intake and treatment costs.

The results showed:

  • Calves gained 15.5% more weight
  • They consumed 12% more starter feed
  • And reduced medical costs by $19 per calf through fewer treatments

Two bar charts compare control and Ralco Calf Program groups. Ralco group shows higher starter feed consumption (84 lbs) and body weight gain (78 lbs), with 12% and 15.5% improvement, respectively. " per calf advantage" at top.

TECHNOLOGY DESIGNED FOR GROWTH


The Ralco Calf Program provides complete care as calves grow

In the first 30 days, milk is a calf’s primary nutrient source. But as they grow, its total nutritional contribution declines, and starter intake must increase to meet their needs. 

Stand Strong for Dairy Calves supports immunity and vigor during the critical early stage. 

Fight Strong Pellet maintains health as starter intake rises, easing the weaning transition. 

The black line represents the combined intake of Ralco technologies over the first 9 weeks of life, showing how the program ramps up during the most stressful time in a calf’s life – weaning.

Together, they form a seamless bridge from milk to starter, helping calves stay eating and growing strong through stress.

Line graph titled "Ralco Calf Program Technology Intake" shows technology intake per unit body weight over 12 weeks for three groups: Stand Strong (green dotted), Fight Strong (yellow dashed), and their combination (black solid).
