Benefits of Cel-Max™

  • 11 lb gain advantage at 78 days
  • 12% less feed required per pound of gain
  • $0.08 lower cost per LB of gain


The results suggest that feeding 1 g/day of Cel-Max™ in the milk replacer for the first 56 days can promote increased calf performance. A statistically significant increase in feed efficiency, as well as average daily gain, were observed in the calves fed Cel-Max™ until weaning. Overall feeding calves Cel-Max™ resulted in lower cost per pound of gain.
