No, all cows calving in the same pasture will not calve in 90 days or less.Herds with a calving season longer than 90 days have cows calving after the breeding season has already started. Without limiting your calving season it will be difficult, if not impossible, to test your calves before they have exposed cows in early gestation to BVD. This exposure may create new PI calves; therefore the money that you spend identifying and eliminating current PI calves may be wasted.
