The Impro company has a long-standing association with specific dairy herd(s) that are managed for the purpose of providing milk product to Impro for processing their whey ingredient. This enables them to ensure that nutrition, animal husbandry and veterinary care is controlled to produce high quality milk. These cows are subjected to various environmental challenges; e.g., vaccinations, for the purpose of producing specific immune factors to help support the immune system in dealing with specific environmental challenges of the cow or calf. Quality control is enhanced by strict adherence to processing, handling and traceability protocols.
