Have you considered the impact winter has on your horse's diet?
As the seasons change, so do the nutritional and physiological needs of horses, with winter significantly impacting hydration and therefore tendon elasticity, fascia health and more. It is important to understand how to adapt care routines to support musculoskeletal health and keep your horses performing at the top level.
🌾 Winter Diet Transitions: From Moisture-Rich Grass to Dry Forage
During warmer months, horses graze on fresh pasture, which contains up to 80% moisture. In winter, this is replaced by hay or haylage, which typically contains only 10–20% moisture. This reduction in water intake from forage alone can lead to systemic dehydration if not properly managed. Alongside this, cold weather often discourages horses from drinking enough. Icy troughs and reduced thirst response mean horses may consume less than required, increasing the risk of impaction colic and compromising cellular hydration.
🧬 Fascia and Tendon Health
Fascia is a connective tissue network that surrounds muscles, organs, and joints. It’s composed largely of water and collagen, and its ability to glide and support movement depends on adequate hydration. Tendons, too, require water to maintain their visco-elastic properties. Dehydrated fascia becomes stiff and adhesive, reducing range of motion and increasing injury risk. Similarly, dry tendons lose their shock-absorbing capacity, making them prone to strain under load.
🐴 Hard Feed and Hay: Fibre vs Fluid
Hard feeds and dry hay are essential for winter energy needs, but they lack the moisture content of fresh grass. Without compensatory water intake or soaked feeds, horses may experience slower digestion and reduced nutrient absorption. This can lead to muscle fatigue and poor recovery.
✅ Practical Tips for Supporting Tissue Hydration
Offer warm or flavoured water to encourage drinking during cold spells
Incorporate soaked feeds like beet pulp or alfalfa to boost moisture intake
Understanding the interplay between diet, hydration, and tissue health is key to maintaining peak performance and comfort for your horse.
