Viral infections in dairy cattle represent a significant challenge to health and productivity due to their systemic metabolic cost, inflammatory burden and prolonged effects on milk production. This white paper reviews the physiological mechanisms underlying production losses during viral infections and outlines a science-aligned supportive framework.

Bluetongue virus (BTV) provides a well-documented example of viral challenge associated with measurable milk yield losses at herd level. In addition, recent peer-reviewed literature has confirmed highly pathogenic avian influenza (HPAI) H5N1 infections in dairy cattle in the United States. This reinforces the importance of preparedness for viral stressors and robust supportive strategies. This white paper reviews the physiological mechanisms underlying production losses during viral infections and outlines a science-aligned supportive framework.

Viral infections in dairy cattle represent a significant challenge to health and productivity due to their systemic metabolic cost, inflammatory burden and prolonged effects on milk production. Antiviral treatment options are limited in food-producing animals. That’s why supportive management strategies that sustain energy availability, hydration, and immune balance are essential to facilitate recovery. This white paper reviews the physiological mechanisms underlying production losses during viral infections and outlines a science-aligned supportive framework.

Reduce dry-off complications without compromising udder health or milk yield. High milk yields at dry-off and delayed teat closure increase the risk of new IMIs. New research shows that an abrupt, well-supported dry-off can improve outcomes for both cow and farmer. Key benefits shown in recent studies: • Significant lower milk production within 24 hours → less engorgement and leakage • Up to 85% fewer leaking quarters • Better metabolic stability around calving • Lower risk of new infections in the next lactation without increases in SCC or mastitis Want to learn which strategies make this possible?

New insights from university research, CRO studies and field data show that targeted support around dry-off can lead to: • Significant lower milk production within 24 hours (Utrecht University), resulting in less udder engorgement and reduced leakage • Up to 85% fewer leaking quarters, a key predictor for new IMIs • Improved metabolic stability around calving, including lower NEFA and better liver parameters • Reduced risk of new infections in the next lactation, without increases in SCC or mastitis Want to learn which strategies make this possible?
