Introduction
The relationship between weather and your horse's digestive health is closer than many owners realise. As Scandinavian spring unfolds with its cool temperatures, cloudy skies, and intermittent rainfall, understanding how these conditions affect your horse becomes critical for maintaining optimal health and wellbeing.
02
How Weather Influences Equine Digestion
When temperatures drop or fluctuate dramatically as they often do during Scandinavian springs (ranging from 3°C to 18°C) (2,3), your horse's digestive system responds accordingly. Cold weather can significantly decrease gut motility—the wave-like muscle contractions that move food through the digestive tract. This slowdown isn't merely uncomfortable; it can create serious health concerns.
During colder periods, horses naturally conserve energy by reducing blood flow to peripheral areas, redirecting it to vital organs. While this biological response is normal, the reduced circulation to the gut can lead to slowed digestion and increased risk of impaction colic—a potentially dangerous condition where food becomes trapped within the intestines.
Perhaps the most concerning aspect of cooler, damp weather is its impact on hydration (7). Studies consistently show that horses tend to drink significantly less water when temperatures drop (8). A typical horse requires 30-45 litres of water daily (1), but consumption can drop by up to 40% during cold spells. This reduction creates a perfect storm for digestive complications:
Behavioural Changes Affecting Feeding Patterns
Cloudy conditions with limited sunlight, as forecasted across Scandinavia (2, 3), can influence feeding behaviours in subtle yet important ways. Reduced daylight hours affect horses' natural grazing rhythms, potentially causing them to consume larger amounts of feed in shorter periods rather than grazing continuously throughout the day.
This altered eating pattern can overwhelm the digestive system, particularly when combined with less movement during wet weather when turnout is limited. The result is often incomplete digestion of feed, creating excess gas and increasing the risk of colic episodes.
Spring in Scandinavia brings another challenge: rapidly changing pasture composition. As temperatures gradually warm to the forecasted 17-18°C in parts of Sweden and Denmark (4, 5), grass begins growing more vigorously, dramatically changing in both volume and nutritional profile.
This sudden shift presents several digestive challenges:
For horses with sensitive digestive systems or those prone to laminitis, these changes can be particularly problematic, requiring careful management during wet, cool springs.
03
How EquiNectar Can Help Support Equine Digestive Health
While weather conditions may present challenges to equine digestive health, appropriate nutritional support can make a tremendous difference.
Enzymatic Support for Changing Forage
EquiNectar's formulation provides a comprehensive blend of active digestive enzymes derived from malted barley that are particularly valuable during seasonal transitions. These naturally occurring enzymes include:
When temperatures fluctuate between 3°C and 18°C as forecast across Scandinavia (3, 4, 5), these enzymes provide consistent digestive support regardless of changing environmental conditions.
Microbiome Support During Weather Transitions
The hindgut microbiome—comprising trillions of beneficial bacteria—is highly sensitive to dietary changes triggered by weather patterns (6). During cooler, damper conditions when horses drink less, this delicate ecosystem can quickly become unbalanced (7).
EquiNectar helps maintain microbiome stability during these challenging periods. By promoting a healthy gut environment, it helps:
A stable microbiome translates to more consistent droppings, reduced gas production, and decreased risk of digestive upset—particularly valuable during the spring's unpredictable weather patterns.
EquiNectar's palatable syrup formulation serves another crucial purpose during cool weather: encouraging both feed and water consumption. When added to feed, its natural sweetness:
During the forecasted rainy conditions across Norway and parts of Sweden during this week and the following week, maintaining adequate hydration becomes particularly important for preventing impaction risks.
04
Practical Application During Changing Weather
For horse owners facing the challenges of Scandinavian spring weather, implementing EquiNectar into daily routines offers practical benefits:
1. During temperature fluctuations: Include EquiNectar as part of your horse's daily routine to maintain digestive efficiency regardless of thermal stress on the digestive system
2. When transitioning to spring grass: Begin supplementation before turnout changes to prepare the hindgut for processing the increased fructan and changing fibre content
3. During periods of reduced turnout: Add EquiNectar to feeds when wet conditions limit movement to help compensate for reduced natural foraging behaviours
05
Beyond Digestion: Wider Benefits During Challenging Weather
The digestive support provided by EquiNectar extends beyond basic gut function to improve overall wellbeing during challenging weather conditions. Horse owners frequently report:
These outcomes are particularly relevant during the cloudy, cool, and humid conditions forecast across Scandinavia, which can otherwise contribute to digestive stress and behavioural changes.
06
Conclusion
While we cannot control the spring weather patterns across Sweden, Denmark, and Norway, we can certainly take proactive steps to support our horses' digestive health regardless of what the forecast brings.
By understanding how the predicted temperature ranges of 3-18°C, cloudy conditions, and intermittent rainfall affect equine digestion, and by implementing supportive measures like EquiNectar, horse owners can navigate seasonal transitions with confidence.
With proper management and appropriate nutritional support, your horse can thrive despite the meteorological challenges that Scandinavian springs inevitably bring.
