BVD Vaccinations Improve Reproductive Performance

11 November 2014

A 45 per cent decrease in abortion and significantly lower rates of fetal infection were reported in cattle vaccinated for bovine viral diarrhea virus.

A recent meta-analysis by researchers at Auburn University explored the impact of bovine viral diarrhea virus (BVDV) vaccination on reproductive performance, finding that fetal infection dropped by nearly 85 per cent in calves from vaccinated dams. 

The results were published in the October 1 online issue of Theriogenology. Additionally, pregnancy rate is increased by approximately 5 per cent in field trials of BVDV-vaccinated animals.

In addition, the researchers conclude that the decision to vaccinate is the most important consideration when a decrease in BVDV associated reproductive disease is desired.

They noted that vaccination, in combination with a sound biosecurity program, can greatly limit the negative reproductive impact of BVDV infection.
