Used as an aid in the prevention of neonatal beef and dairy calf scours caused by K99+ E. coli and Coronavirus.
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.
