First Defense Tri-Shield
First Defense Tri-Shield is a colostrum-derived boost for newborn calves that aids in the reduction of scours caused by K99 E. coli and bovine coronavirus, while also reducing severity and duration of scours caused by bovine rotavirus. First Defense for calves gives newborn animals specific immunoglobulins at the gut level to deliver immediate protection against disease. Additional antibodies are absorbed into the bloodstream.
For best results, First Defense Tri-Shield gel should be administered to calves orally, within 12 hours after birth. Do not delay colostrum. Oral gel.
