Fragile at birth, curious within hours, the foal embodies the promise of a strong future in the world of horse breeding. This young horse, still dependent on its mother, goes through key stages in physical and behavioral development. From feeding to training, each phase requires special attention. Whether you’re a breeder, enthusiast, or horse owner, understanding a foal’s specific needs is essential to give it a healthy and balanced start in life.
A foal is a young horse, male or female (a female is called a filly), less than one year old. From birth, the foal enters a period of rapid development: it almost doubles its weight in a few weeks and begins interacting with its environment within hours.
A foal is considered a newborn until 48 hours old, then an infant until six months, and a weanling once it is weaned. This classification allows breeders to closely monitor growth stages and adapt care accordingly.
Its digestive system, skeleton, immune defenses, and social behaviors evolve quickly—but remain fragile. The first few days are critical for detecting any abnormalities or deficiencies.
In its first weeks, the foal feeds exclusively on mother’s milk, which is rich in antibodies, vitamins, and essential calories. The colostrum, produced just after birth, is vital for developing passive immunity.
From 2 to 3 weeks of age, the foal begins to graze, imitating the dam. This is the ideal time to gradually introduce a balanced diet (quality hay, foal-specific pellets, and mineral-rich feed). Access to fresh water must always be available.
Weaning usually takes place between 5 and 7 months of age, and should be done progressively. It can be stressful: minimizing stress involves providing a stable environment, social contact with other foals, and a complete, digestible diet.
Specific supplements (calcium, phosphorus, vitamins A, D, E) help support bone growth and prevent joint issues.
From birth, the foal requires regular veterinary care: checking the suckling reflex, limb alignment, first deworming at around 15 days, then monthly until 6 months. Vaccinations usually start around 6 months, including flu and tetanus.
The foal quickly begins to interact with humans—this is known as early handling or pre-training. Gentle handling, familiarization with a halter, grooming, and hoof care help build trust and cooperation. However, overstimulation or premature physical training should be avoided.
Social development is just as important: living in a herd or with other foals helps the young horse learn equine social codes, engage in play, become independent, and reduce behavioral issues in adulthood.
In the first months of life, foals are highly vulnerable to both infectious and developmental diseases, due to their immature immune systems and rapid growth. One of the most feared is rhodococcosis, a serious bacterial infection caused by Rhodococcus equi. It primarily affects foals aged 1 to 6 months, presenting as slow-developing pneumonia, with persistent cough, fever, shortness of breath, and sometimes diarrhea or abdominal abscesses. Early diagnosis through thoracic ultrasound is vital, as the disease can be fatal if not treated promptly.
Juvenile osteoarticular disorders, such as osteochondrosis, are also common. These involve abnormal cartilage ossification during growth and are often linked to genetics, nutrition, or accelerated development. Symptoms include lameness, joint swelling, and stiffness. Early diagnosis enables dietary adjustments and, in some cases, surgical intervention.
Other frequent conditions include neonatal diarrhea (caused by rotavirus, parasites, or nutritional errors), septic joint infections (often stemming from umbilical infections), and respiratory diseases (bronchitis, pneumonia).
Prevention relies on strict hygiene during foaling, adequate colostrum intake, appropriate vaccination, and close veterinary monitoring to detect early signs such as fever, lethargy, appetite loss, cough, or lameness.
At what age can a foal be weaned from its mother?
Weaning generally occurs between 5 and 7 months, once the foal can eat independently. Gradual weaning is key to avoiding stress and behavioral problems.
What should be monitored in the first days after birth?
Essential checks include colostrum intake, strong suckling reflex, urination, defecation, body temperature, and absence of joint deformities. Any abnormality should be reported to a vet immediately.
What should a weaned foal eat?
A balanced diet including quality hay and foal-specific feed (rich in minerals, protein, and vitamins) is essential to ensure healthy growth.
When should a foal’s training begin?
From the first few weeks, through gentle handling and familiarization with humans. The goal is not to train, but to build a calm and cooperative relationship.
Can a foal live alone?
No. Social contact with peers is essential for learning equine behavior codes. Isolation may cause anxiety, behavioral issues, and developmental delays.
How do I know if a foal is healthy?
A healthy foal is curious, active, suckles regularly, has normal stool consistency and a shiny coat. Apathy, diarrhea, or poor growth require prompt veterinary attention.
High/low syndrome in horses is a podal asymmetry characterised by a “high” foot (high heels, short toe) and a “low” foot (low heels, long toe). This condition results from an unequal load on the limbs, influenced by anatomical, biomechanical and postural factors. It can lead to joint and tendon pain and reduced performance. Management is … Read more
The arrival of autumn is a risky time for horses, particularly because of the increased presence of acorns and young oak shoots in pastures. These elements, although natural, can be toxic to horses if ingested in large quantities. The tannins contained in acorns and oak leaves cause digestive and kidney problems, and sometimes serious poisoning. … Read more
Spikelets, the tiny seeds of grasses, can be a real danger to our four-legged friends. Often invisible and unobtrusive, they embed themselves in the coat and can lead to serious complications if not detected in time. What are spikes? Spikelets are dry spikes of grass, characteristic of plants in the Poaceae and Cyperaceae families. They … Read more
Rhodococcosis, caused by the bacterium Rhodococcus equi, poses a significant threat to foals, particularly those aged between 1 and 6 months. This bacterial infection, which manifests itself mainly as pneumonia, can lead to serious and even fatal complications if not diagnosed and treated in time. Foals reared in dusty, dry environments are particularly vulnerable. What … Read more
Juvenile osteochondral disease (J OCD) is a complex group of disorders affecting the development of cartilage and subchondral bone in young horses. These conditions, often grouped under the umbrella termosteochondrosis, are of major concern to breeders and veterinarians because of their significant impact on the health and future performance of equines. AOJ can manifest as … Read more
Tetanus is a serious bacterial disease that mainly affects horses. The bacterium Clostridium tetani produces a potentially fatal neurotoxin, causing uncontrollable muscle spasms. Horses are particularly susceptible to this infection, which can often be fatal. What causes this disease? Tetanus is caused by the bacterium Clostridium tetani. This anaerobic bacterium develops in the absence of … Read more
Recurrent equine summer dermatitis (RESD ) is a chronic, itchy skin condition that affects many horses, ponies and donkeys. Characterised by intense itching and skin lesions, this seasonal condition can become a real nightmare for equine owners. In this article, we explore the causes, symptoms, diagnostic methods, available treatments and preventive measures to combat this … Read more
