Our proprietary PathWhey technology gently removes the non-immune components of colostrum — such as fat and casein — and concentrates only the nutrient-dense whey fraction to deliver high levels of immune components. This gives calves colostrum with higher quantities of IgG and growth factors that support healthy immune and inflammatory responses.
With its high IgG content and unmatched solubility, studies have shown that Premolac has a 98%+ successful passive transfer of immunity rate when used as a replacer.
When used as a supplement to maternal colostrum, Premolac significantly increases IgG absorption efficiency and immune status in newborn calves.
Premolac is also a highly effective daily health supplement, with studies showing a 70% reduction in mortality rates when incorporated into milk or milk replacer.
Born with essentially no immune system, calves rely exclusively on colostrum to provide protection during the first few weeks of life. Consumption of high-quality colostrum provides passive immunity while the calf’s immune system develops. Failure to provide passive immunity can result in increased calf sickness and death.
