After Weaning: The Lasting Impact of Separation on Foal Stress Levels

Foal, Horse care

Weaning is a significant event in a foal’s life, as it marks the beginning of their separation from their dam and the transition to solid food. It’s no surprise that this period can be a stressful time for both the foal and the mare. A study conducted by researchers at the University of Kentucky found that foals exhibit increased stress levels for weeks after weaning. As a responsible horse owner, it’s crucial to understand the effects of weaning on foals and how to manage their stress during this period.

What Happens to Foals During Weaning?

Foals are social animals, and their bond with their dam is essential for their physical and emotional well-being. Weaning disrupts this bond, which can cause emotional distress in foals. Foals may exhibit a range of behaviors during weaning, such as vocalizing, pacing, and decreased appetite. They may also become more susceptible to illness and experience weight loss.

Foals’ stress response to weaning is primarily triggered by the removal of the mare’s milk. The sudden change in diet, along with the loss of their primary source of comfort, can lead to increased levels of cortisol, a stress hormone, in their bodies. In the study mentioned above, the foals’ cortisol levels were measured three weeks after weaning and were found to be significantly higher than before weaning.

How do I know if my foal is in high stress level?

To determine if a foal is experiencing high levels of stress, veterinarians can measure the foal’s cortisol levels in the blood or feces. Additionally, they can observe the foal’s behavior, such as vocalizations, agitation, and reduced appetite, as these are all signs of stress. It’s important to monitor foals closely during the weaning process to ensure that their stress levels are managed appropriately.

Managing Foal Stress During Weaning

It’s essential to manage a foal’s stress during weaning to ensure their well-being and reduce the risk of illness or injury. Here are some tips for managing foal stress during weaning:

🍼Gradual Weaning:

Gradual weaning can help reduce the stress of separation for both the foal and the mare. This method involves reducing the foal’s milk intake slowly over several weeks while gradually increasing their solid food intake.

🐎Socialization:

Foals are social animals, and socialization with other horses can help reduce their stress levels. Weaned foals should be turned out with other young horses to help them adjust to their new environment and establish social bonds.

🌳Environment:

A foal’s environment can have a significant impact on their stress levels. A quiet, calm environment with minimal changes and disruptions can help reduce stress during weaning.

🌾Nutrition:

Proper nutrition is essential for a foal’s physical and emotional well-being. Foals should be provided with high-quality hay, grain, and clean water. Supplements, such as probiotics and electrolytes, can also be helpful during the weaning process.

👩‍⚕️Veterinary Care:

Regular veterinary check-ups can help ensure that weaned foals are healthy and free of illness or injury.

Here is one of our client’s experience:

Jane is a horse breeder.She weaned her foal at six months of age as recommended by her veterinarian. The foal showed signs of stress, including weight loss and behavioral changes such as increased nervousness and restlessness. Despite her efforts to provide a comfortable environment and regular care, the foal’s stress levels remained high for several weeks after weaning. The breeder consulted with her veterinarian, who suggested some management changes and supplements to help the foal cope with the stress of weaning.

To help the weaned foals in this case, the Jane implemented a gradual weaning process and increased social support for the foals. By gradually reducing the time the foals spent with their dams over a period of several weeks, the foals were able to adjust to the separation more easily, and their cortisol levels were lower compared to foals who were abruptly weaned. Additionally, the foals were given more opportunities to socialize with other horses, which helped to reduce their stress levels and promote their overall well-being.

It’s important to note that every situation is unique, and what works for one foal may not work for another. Therefore, it’s important to work closely with a veterinarian or equine behaviorist to develop a weaning plan that is tailored to each individual foal’s needs and temperament. By taking a proactive approach to managing foal stress levels during and after weaning, horse owners can help to ensure the long-term health and well-being of their young horses.

Weaning process plan with a timeframe:

Day 1-3: Remove the mare from the foal’s living area but allow them to maintain visual and auditory contact with each other.

Day 4-6: Move the mare to a location out of sight and earshot of the foal, but still within the property. The foal should be kept in familiar surroundings and provided with plenty of hay, water, and social interaction with other foals or horses.

Day 7-10: Move the mare to a location further away, out of sight and earshot of the foal. The foal should continue to receive the same care and attention as before, and may benefit from the addition of a companion animal to provide social support.

Day 11-14: The foal should now be able to manage without the mare. Continue to monitor the foal’s stress levels and provide plenty of social interaction with other horses.

By gradually separating the mare and foal over a two-week period, the foal should experience less stress and have an easier transition to independence. It’s important to keep in mind that every foal is different and may require adjustments to the weaning process based on their individual needs. It’s always best to work closely with your veterinarian or equine professional to develop a weaning plan that is tailored to your horse’s specific situation.

Take-away:

Weaning can be a stressful time for both foals and horse owners. However, by implementing a gradual weaning process and providing social support, you can help to reduce stress levels and ensure the well-being of your foal. Remember to consult with your veterinarian and develop a weaning plan that is tailored to the specific needs of your foal. Good luck with your weaning process, and may your foal grow up happy and healthy!

Here are some research papers you can dig-in more :

Several studies have investigated the effects of weaning on foal stress levels. One study published in the Journal of Equine Veterinary Science found that foals experience a significant increase in cortisol levels, a hormone associated with stress, after weaning. The study also found that foals who received more social support, such as spending time with other horses, had lower cortisol levels after weaning.

Another study published in the Journal of Animal Science found that foals who were weaned gradually over a period of several weeks had lower cortisol levels and showed fewer signs of stress compared to foals who were abruptly weaned.
