Fetal Protection Matters
Reproductive Diseases Can Be Costly
The reproductive forms of the following viral diseases can pose a threat to profitability:
Bovine viral diarrhea (BVD)
- Caused by bovine viral diarrhea virus Types 1 and 2
- Can lead to abortion, fetal death/resorption and/or congenital malformation of the fetus
- Fetal infection can result in the birth of weak or BVD persistently infected (PI) calves1
- BVD PI cattle can serve as a long-term source of infection for the herd
Infectious bovine rhinotracheitis (IBR)
- Caused by bovine herpesvirus 1 (BoHV-1) which is commonly referred to as IBR virus
- Can lead to sporadic abortions and abortion storms1
- The virus can hide in the body and be reactivated when cattle are stressed or injured
- Viral shedding can lead to infection of other cattle
Set Cattle Up For A Lifetime of Success
An effective reproductive vaccine program, coupled with good nutrition, can help heifers conceive earlier and potentially extend the length of their productive lives. In fact, research shows that heifers that conceive in the first 21-day breeding period demonstrate increased longevity.4
