Proven Success Stories
“I’ve received consistent reports that CONVERT™ BIG Calf Powder gives calves an extra gear of appetite and overall health. Calves come bouncing out of the hutches and want to eat to the bottom of the bucket.”
“CONVERT™ BIG Calf Powder has been a GAME CHANGER! Even during a harsh winter, with temperature swings of 60°F and lows as cold as -20°F several times, we saw healthier calves overall. Our calves living outside in hutches had zero cases of pneumonia or scours, resulting in a significant decrease in treatment costs for animals under six months old. That savings alone far outweighs the cost. All of this, on top of raising stronger, healthier calves ready to take on the stresses of weaning with ease.”
