We have been using first defense for 3 years now and have not lost any calves to scours.

Advantages: We give it to all the calves born on the farm within the first couple of hours.

We love our First Defense Boluses. Every calf on our farm receives one of these within the first twelve hours after birth.

Advantages: We see a higher survival rate in our calves compared to other farms.

Disadvantages: The boluses are sometimes too big for our smaller Jersey calves, but than we just open them up and pour the powder inside the bolus into our calves' colostrum.
