Digestarom® Dairy: Managing Heat Stress in Dairy Cows | Farmer Perspective Sweden

Heat stress is one of the biggest risks to dairy cow performance—impacting feed intake, gut health, milk yield, and milk solids.

In this farmer perspective from Rosdala Farm in southeast Sweden, dairy farmer Martin Greif shares his experience managing these challenges in a high-performing herd of approximately 1,000 cows producing over 13,500 kg ECM annually.

As temperatures rise, maintaining consistent dry matter intake (DMI) and rumination becomes critical. Martin explains how Digestarom® Dairy was introduced ahead of the summer period to help support rumen function, stabilize feed intake, and maintain production under heat stress conditions.

On this farm, the following changes were observed during the evaluation period: 

• More consistent feed intake
• Increased rumination and chewing activity
• Improvements in milk fat and protein content
• Positive effects on overall herd health and resilience
• Support for rumen function during periods of heat stress

Digestarom® Dairy is a phytogenic solution combining essential oils and plant extracts designed to support rumination, feed intake consistency, and gut integrity—helping cows maintain performance during challenging conditions.

As heat stress becomes more frequent across dairy regions, supporting cow resilience and feed efficiency is increasingly important for sustaining herd productivity.
