Approximately 10 years ago we had a minor flair-up of scours in our herd… The following year we administered First Defense to every newborn. Scours became basically non-existent.
Carrousel Farms, Beef Farm
We began using First Defense during the 2013 calving season when we were treating what seemed like half of our calves for scours. Since using First Defense, we have treated only four calves for scours out of our 600 head herd. First Defense really works!

First Defense is like an insurance policy that pays for itself in spades. Say you cut your death loss from, conservatively, 8 to 2 percent… That fuels the growth of the whole dairy.
Southfield Dairy, Dairy Farm
First Defense works, because we’ve seen the outcome of its absence. Two different times, we chose to cut back and stop giving it and both times the calves got sick. We’ve learned our lesson. My advice: get your calves on it, and stick with it.
