Foal Sleep Patterns: Why Do They Nap So Much?

are 2 week old foals supposed to sleep a lot

Foals require a lot of sleep, especially when they are very young. In fact, newborn foals will spend most of their first week sleeping and eating. By the time they are two weeks old, they will be experimenting with solid food, but they will still be drinking their mother's milk. Foals under three months of age require around 12 hours of sleep per day, which is four times more sleep than an adult horse. If a foal appears to be sleeping excessively and does not stand up or play, it may be a sign that the foal needs to be evaluated by a vet. However, as long as a foal is nursing normally and displaying energy when it is awake, there is probably no cause for concern.

Foals require around 12 hours of sleep per day for their first 3 months

Foals require approximately 12 hours of sleep per day during their first three months. This is about four times the amount of sleep that adult horses need daily. Foals will spend most of their first week sleeping and eating. They may also take power naps after an hour or two of play to recharge. After three months, foals will gradually sleep less as they get older. They may also start to stand up to sleep more often instead of lying down.

It is perfectly normal for foals to nap frequently and sometimes a lot. As long as they display energetic behaviour when awake, have bright eyes, nurse normally, and exhibit spunkiness, they are normal youngsters. Foals also undergo growth spurts, similar to human infants, which cause them to sleep more and eat slightly less.

In their first week of life, foals are particularly vulnerable to developing diarrhoea due to their underdeveloped immune system and microbiome. They are also susceptible to various conditions, such as foal meconium impaction, bladder rupture, and joint ill. Additionally, neonatal maladjustment syndrome, or dummy foal syndrome, can occur when foals don't receive adequate oxygen in the uterus or during and after birth, resulting in strange behaviour and neurological signs.

By the time foals are one to two weeks old, they may start experimenting with solid food by nibbling on grass or hay. However, they typically don't fully transition to solid foods, including hay and grain, until they are around 2 to 2.5 months old. During this period, it's important to ensure that nursing mares are getting enough nourishment, as nursing can be demanding on their bodies.

Excessive sleep could be a sign of neonatal maladjustment syndrome

It is perfectly normal for a foal to sleep a lot during its first week. In fact, foals under 3 months of age require around 12 hours of sleep per day, which is four times the amount that adult horses need. After a couple of hours of play, a foal may need a power nap to recharge.

However, excessive sleep could be a sign of neonatal maladjustment syndrome (NMS), also known as dummy foal syndrome. This rare condition affects just 1-2% of newborn foals, causing neurological abnormalities and strange behaviour. Foals with NMS may appear healthy at birth, but soon exhibit neurological signs, such as excessive sleep, flat ears, and a sticky forehead (from unsuccessful attempts to nurse).

NMS is believed to be caused by low oxygen levels during birth, which affect the foal's brain. The condition can also cause metabolic problems, including failure of thermoregulation, gut motility, and reduced ventilation. In some cases, NMS may be linked to human interventions or rapid birth deliveries.

One novel treatment for NMS is the Madigan Squeeze Technique (MST), which involves applying pressure to the foal's ribcage for 20 minutes to mimic the normal birth canal pressures. This treatment aims to signal the foal's transition from sleeping in the womb to wakefulness after birth.

Interestingly, researchers have noted similarities between NMS in foals and childhood autism spectrum disorder in humans. The tactile response from foals with NMS may also be comparable to the benefits of touch for newborn babies with illnesses. These connections highlight the potential for cross-species learning and the development of effective treatments.

Diarrhoea is common in foals during their first week of life

Foals are known to sleep a lot during their first week of life, and this is perfectly normal behaviour. They will spend a good majority of their first week sleeping and eating. Under three months of age, foals require around 12 hours of sleep per day, which is four times more than an adult horse. After the three-month mark, they will gradually start sleeping less and less.

Now, during this time, diarrhoea is common in foals and can be caused by a variety of factors. Firstly, foals are vulnerable during their first week of life because they do not yet have an established immune system or microbiome, which can make them susceptible to "foal heat" diarrhoea. This type of diarrhoea typically occurs between 7 and 12 days of life and is often not serious. However, bouts of diarrhoea within the first week may indicate an underlying problem.

One of the critical signs of a healthy foal is their ability to stand and nurse. If a foal is experiencing diarrhoea and is not feeding off the mare, it should be seen by a vet immediately. Diarrhoea can lead to dehydration and other ailments if not addressed promptly. Foals with abdominal discomfort may benefit from a brief period of gastrointestinal rest (12-24 hours), and fluid therapy may be necessary if a foal is not nursing for extended periods.

There are various causes of diarrhoea in foals. One cause can be ingesting milk infected with larvae or eggs/larvae in faeces, known as parasitic burden. Additionally, certain bacteria, such as C. difficile and C. perfringens, have been associated with diarrhoea in foals. Antibiotic administration has also been identified as a risk factor for diarrhoea. Furthermore, the ingestion of sand, dirt, or other foreign materials can cause mechanical irritation to the gastrointestinal tract and result in diarrhoea.

To prevent and manage diarrhoea in foals, here are some key points:

  • Probiotics: Administering probiotics during the first week of life can help establish a healthy digestive system and prevent diarrhoea.
  • Quarantine and Hygiene: Quarantine visiting horses for at least two weeks, and ensure proper hygiene practices when handling animals with diarrhoea.
  • Worming: Routine worming of the mare during pregnancy and lactation can help prevent parasitic infections in foals.
  • Discontinuation of Antibiotics: If practical, discontinue antibiotic treatment as it can alter the gut microflora and contribute to diarrhoea.
  • Supportive Therapy: Provide supportive therapies such as yoghurt and gastroprotectants to aid in gut health.
  • Avoid Overcrowding: Avoid overcrowding in foaling paddocks to minimize the risk of infection spread.

Foals are born without teeth, but they grow quickly

Foals are born well-developed, which helps them stay with the herd and escape predators. However, they still experience rapid growth in the first few years of life, including changes in the size of their heads. To accommodate this growth, young horses have several adaptations to their teeth and skulls. For example, the number of cheek teeth a foal possesses will double between birth and approximately four years of age.

In the first 24 hours of a foal's life, it will stand, play, suckle, urinate, and sleep. This process repeats throughout the day. Foals are at risk of developing diarrhoea within the first week or two of life due to their underdeveloped immune systems. They are also vulnerable to other dangerous conditions, such as neonatal maladjustment syndrome, which can cause excessive sleeping. However, sleeping a lot is normal behaviour for baby horses, and they require around 12 hours of sleep per day under three months of age.

Foals may eat their mother's manure to kickstart their immune systems

It is normal for foals to sleep a lot during their first week. They will spend a good majority of their first week sleeping and eating. They require around 12 hours of sleep per day when under 3 months old, which is four times what an adult horse needs. After the 3-month mark, they will begin to sleep less and less.

Now, let's discuss why foals may eat their mother's manure. Firstly, it is important to note that eating manure, or coprophagy, is a normal but transient stage of a horse's natural development. Foals typically eat manure, usually fresh from their mother, from about 5 days old until around 3 months of age. This behavior helps populate their hind gut with important digestive microbes, as their digestive system is initially void of any microbes critical for breaking down food.

Additionally, eating manure stimulates a foal's immune system. Manure often contains parasites and eggs, which, if ingested, require the foal's immune system to activate and protect the foal's health. This is similar to a natural vaccination. The manure may also contain deoxycholic acid, which supports digestive system immunity and promotes myelination of the nervous system, essential for neurological development.

It is worth noting that the main concern with manure consumption is the risk of infection from internal parasites. Therefore, it is crucial to deworm broodmares in the weeks leading up to parturition and deworm young horses starting at 2 to 3 months of age.

Frequently asked questions

Yes, it is perfectly normal for foals under 3 months old to sleep a lot. Foals require around 12 hours of sleep per day, which is 4 times what an adult horse needs. Foals will spend most of their first week sleeping and eating, and will continue to nap often in their second week.

A healthy foal will stand, nurse, drink, and urinate a lot. The urine should be clear. If your foal is sleeping excessively, not standing or playing, has flat ears, and a sticky forehead, these could be signs that your foal is unwell and should be evaluated by a vet.

In their second week, foals may start to experiment with grass or hay, although they won't start to include solid foods in their diet until they are around 2 to 2.5 months old.
