The Key Ingredient: All-Milk Proteins

A newborn's gut is built for milk. The wrong ingredients can set infant animals back before they even get started. The right ingredients work with their biology from day one for optimal digestion, nutrient absorption and healthy growth. That’s why Calf Start milk replacers are made with 100% all-milk proteins.

Newborns Are Meant for Milk

In those first weeks, newborns' digestive systems are designed to process one thing: milk. All-milk proteins align perfectly with their natural biology, supporting optimal development during this critical growth phase.

Better Nutrient Absorption 

Plant proteins like soy contain antigens that can trigger inflammation and damage the gut's absorptive surface—which means fewer nutrients actually get through. All-milk proteins don't carry those anti-nutritional factors, so the gut stays intact and does its job.

Less Risk of Scours 

Scours is one of the top concerns for anyone raising young animals, and gut irritation from plant proteins is a common cause. Soy flour protein, for example, can trigger inflammation that damages the gut's absorptive surface. All-milk proteins don't carry those anti-nutritional factors, so the gut stays intact and able to do its job.

No Soy

Some milk replacers use soy flour as a lower-cost alternative. That savings comes at the infant animal’s expense, because soy introduces fiber that young digestive systems can't efficiently process. That’s why Calf Start products use 100% all-milk proteins.

Boosted by Fats, Prebiotics and Probiotics

The Calf Start foundation is 100% all-milk proteins, but it doesn't stop there. The formula includes coconut oil for rapid, easy-to-digest energy, plus BioPrime Technologies, a blend of prebiotics and probiotics to establish healthy gut flora. No shortcuts—just ingredients that work together.
