Nor-Feed Unveils Groundbreaking Study on Dairy Cows' Performance Enhancement

Nor-Feed’s Nor‑Grape® BP‑O Enhances Antioxidant Defenses and Heat Resilience in Dairy Cows. A study published last week in the Journal of Dairy Science confirms that Nor‑Grape® BP‑O, a rumen‑protected grape extract enriched with grape polyphenols, significantly improves antioxidant status and heat tolerance in dairy cows.

Key Findings from the Study:

• Core Performance Benefit: Cows receiving Nor‑Grape® BP‑O showed enhanced milk production under heat stress conditions without compromising milk quality, compared to those in the control group.

• Heat Stress Mitigation: Supplemented cows exhibited reduced rectal temperature (RT) and lower heart rate (HB), indicating less internal heat generation and improved heat dissipation.

• Antioxidant Gains Confirmed: In separate trials (ONIRIS, Nantes Veterinary School), supplementation with Nor‑Grape® BP‑O raised serum antioxidant activity by 44% in heifers compared to controls.

This product is a wax-encapsulated grape extract designed to resist degradation during rumen fermentation, thereby preserving the integrity and efficacy of its active polyphenols—flavonoids, anthocyanins, and proanthocyanidins.

These results demonstrate that rumen-protected grape polyphenols can play a meaningful role in:

• Supporting oxidative balance

• Enhancing heat stress resilience

• Supporting production stability in challenging climates
