Optimal health for mare and foal
The birth of the foal has gone well, the young animal is frolicking in the pasture, and the mare is doing well as a mother. That is what every breeder dreams of. After a good start, how do you ensure that both mare and foal continue to thrive? What should you pay attention to, and how can you support both?

Breeding

During the first three months, the foal receives its nutrients (and therefore building blocks) almost exclusively through the mare’s milk. The mare produces up to 30 liters of milk per day for this purpose. That is a top-level performance and demands a lot from the mare. She also requires a large amount of nutrients, which she must obtain from her diet. In addition to hay and grass, extra carbohydrates, proteins, vitamins, and minerals are important.
Mare feed
Most breeders provide their mares with specialized mare feed in the period leading up to foaling and during the first months afterward. There are different types of this feed available. For mares that are sensitive to high sugar levels or tend to gain weight easily, there are also variants with lower levels of fast sugars that still contain all the nutrients needed for both mare and foal. If you notice your mare gaining fat around the tail head or shoulder, you can reduce the amount. If your mare is losing weight and muscle mass, you should increase the amount. Increasing pasture time can also help (if possible).
Free movement
The development of the foal’s bones, tendons, ligaments, and joints begins from day one. In addition to the necessary building materials, movement is crucial for developing a healthy musculoskeletal system. Your foal needs free movement from the very first day. For early foals born in January or February, this can be challenging in bad weather, but it is still important to provide as much opportunity as possible. Foals born in April or May should preferably be turned out to pasture as soon as possible. Movement and play stimulate healthy bone growth and lay the foundation for a sound riding horse in the future.
Supplements
The most important minerals for bone development are phosphorus, calcium, magnesium, and silicon. Phosphorus and calcium are sufficiently present in mare feed. Magnesium and silicon can be limiting factors in some cases. Magnesium is often present in low amounts in grass and hay, so it may be wise to supplement it, preferably in the form of a liquid magnesium chelate. If your mare has access to grass, she likely also gets a fair amount of silicon. However, for horses that mainly live on hay, this mineral may be limited in the diet. Since silicon is extremely important for the healthy development of tendons, ligaments, cartilage, and bones in the foal, it is advisable to supplement it as well when horses have limited access to fresh pasture.
