What dietary supplements should be given to your horse in winter?

Winter can be a delicate period for horses. They go out less, spend more time in the stable, and mainly feed on hay. Combined with the cold and humidity, these factors can lead to a loss of condition, energy imbalances, and the onset of joint stiffness. Adapting their diet becomes essential. Terwagne, a specialist in equine dietary supplements, presents the most suitable solutions to meet the needs of each horse and preserve its well-being throughout the winter season.

Which vitamin should be given to a horse all year round?

Horses in winter eatingThe essential supplement for all horses, in every season, is the Mineral Vitamin Supplement (MVS). Highly concentrated, it compensates for deficiencies related to daily diet. It provides essential trace elements (zinc, copper, selenium) as well as vitamins A, D, E, and B, necessary for the proper functioning of the body.

The MVS contributes to the maintenance of immunity, energy, coat quality, hooves, and muscle tone.

It is the essential dietary supplement, suitable for all profiles: horses in pasture, in stalls, seniors, leisure or sport horses, and even foals.

How to adapt dietary supplements according to the horse's profile?

Each horse has specific needs, especially in winter. After adding the MVS, further supplementation can be targeted according to the horse's age, physical condition, or sensitivity.

Supplements for older horses

Older horses have more difficulty maintaining their condition in winter. Chewing becomes more complicated, digestion less effective, and nutrient assimilation decreases. It is therefore important to support their body with appropriate supplements.

Equilannoo Senior Mix is ideal for supporting them during this period: it supports immunity, digestion, assimilation, and mobility, to preserve their vitality and body condition.

Additionally, Equilannoo Fiber Mash is a valuable aid. Rich in fibers and vitamins, it improves nutritional intake and helps keep senior horses in good overall condition.

Supplements for horse joints

What supplements for an arthritic horse in winter? Cold, humidity, and reduced outings can exacerbate joint stiffness and discomfort in horses, especially those prone to arthritis. Certain dietary supplements can support their mobility and locomotor comfort.

Terwagne offers several effective solutions:

  • Harpagophytum: known for its natural anti-inflammatory properties, it helps improve mobility and reduce stiffness.
  • Ungula Locomotion: contributes to joint comfort and proper locomotor function.
  • Vita Move: promotes flexibility and recovery, especially after exertion.

These supplements are particularly recommended for arthritic horses or those experiencing winter stiffness.

Dietary supplements to maintain the horse's muscle mass in winter

Some horses tend to lose muscle during winter, particularly due to reduced exercise and protein intake. To preserve their muscle mass, Equilannoo Muscle Plus provides excellent support thanks to its specific formulation.

Ungula Spirulina can also be added to the diet: rich in proteins, minerals, and natural antioxidants, it contributes to maintaining physical condition and muscle tone.
