First Defense® for Scours

First Defense® is the only USDA-licensed, orally delivered scours preventive product on the market for calves with claims against E. coli K99 and coronavirus (two leading causes of scours). We are working to add a third claim (rotavirus) to our product line during 2017. First Defense® provides bovine antibodies that newborn calves need but are unable to produce on their own immediately after birth. Our milk antibody products provide Immediate ImmunityTM during the first few critical days of life when calves need this protection most.

Studies have shown that calves that scour are more susceptible to other diseases later in life and under-perform calves that do not contract scours. The direct, two-part mode-of-action of First Defense® delivers specific immunoglobulins at the gut level to immediately protect against disease, while also providing additional antibodies that are absorbed into the bloodstream. These circulating antibodies function like a natural timed-release mechanism, as they are re- secreted into the gut later to provide extended protection. A single dose of First Defense® provides a guaranteed level of protection proven to reduce mortality and morbidity from two major causes of calf scours.
