Vaccination is an important mainstay of biosecurity and disease prevention in livestock farming. Vaccination failures represent an economic burden for the farmer. Polyphenol supplementation, is a great source of antioxidants for animals and could help reduce oxidative damage and improve the success of vaccination. For this reason, through a field trial, we evaluated the effect of a rumen-protected grape extract supplementation around vaccination on the immune response in young ruminants.
Supplementing heifers with a dry grape extract around
The trial was conducted on 22 heifers (aged from 6 to 8 months) from the same farm. These were divided into 2 group:
· BP-O group: Rumen-protected dry grape extract supplementation, Nor-Grape® BP-O
· Control group: No supplementation
Results show that the heifers from the BP-O group tended to have a greater overall antibody response to BRSV and PI-3 V. A greater total antioxidant capacity was also observed in the supplemented group.
Thus, since supplemented animals became seropositive faster and long-term immunity appeared to be improved, this supplementation strategy could be of interest to enhance the immune response during a vaccination episode by reducing oxidative stress.
Our 100% natural rumen-protected grape exctract
Nor-Grape® BP-O is a rumen-protected grape extract standardized in polyphenols which provides soluble biological antioxidants that help compensate oxidative stress and support the animals’ immune defenses.
