Ensuring a newborn foal gets the best start in life is a top priority for any horse owner. Plasma therapy is one of the most effective ways to support a foal’s immune system. This life-saving treatment helps protect against infections, strengthen immunity, and improve long-term health. Here’s why foal plasma therapy is crucial to neonatal care and how it benefits young horses in the long run.
Why Should You Give Plasma After a Foal Is Born?
Foals are born with a developing immune system that relies heavily on the antibodies they receive from their dam’s colostrum. However, not all foals ingest or absorb enough colostrum in the first few hours after birth, putting them at risk of infection. Plasma therapy bridges this gap by providing essential antibodies that help protect against common equine diseases.
Foals with failure of passive transfer (FPT), meaning they did not receive enough antibodies from colostrum, are particularly vulnerable to infections. Administering plasma can help boost their immune response, reducing the likelihood of life-threatening illnesses such as sepsis, pneumonia, and joint diseases. Many equine hospitals, including Signature Equine Hospital, recommend plasma therapy for all foals.
The Importance of Rhodococcus in Plasma to Help Protect Foals
One of the most significant threats to foals is Rhodococcus equi, a bacterial infection that causes severe pneumonia. This disease is a leading cause of respiratory illness in foals between one and six months old. Plasma therapy enriched with Rhodococcus antibodies helps protect foals by providing them with targeted immune support against this dangerous bacteria.
Since Rhodococcus equi thrives in dusty environments and is commonly found in soil, foals on breeding farms or high-risk areas benefit greatly from plasma containing these antibodies. Administering plasma early can significantly reduce the chances of developing severe pneumonia and improve survival rates.
When to Give a Foal Plasma
The timing of plasma administration plays a crucial role in its effectiveness. Here are some key situations when plasma therapy is most beneficial:
Within the first 24 hours – Foals that did not receive adequate colostrum should receive plasma as soon as possible to ensure they acquire necessary antibodies.
For premature or weak foals – These foals often struggle with immunity and require extra support to fight off infections.
If blood tests indicate low antibody levels – A simple IgG test can determine whether a foal has received enough passive immunity from colostrum.
Before exposure to high-risk environments – If a foal is in an area with known cases of Rhodococcus equi or other infectious diseases, plasma therapy can act as a preventive measure.
An experienced veterinarian should always administer the proper dosage of plasma transfusions and continue monitoring the foal.
Benefits of Plasma for Foals Long Term
Plasma therapy isn’t just about short-term immune support—it also offers significant long-term health benefits, including:
Stronger Immune System – Foals that receive plasma therapy have enhanced immunity, making them more resilient to infections as they grow.
Better Respiratory Health – Protection against Rhodococcus equi means a reduced risk of chronic lung damage or recurrent pneumonia.
Improved Growth and Development – Healthier foals are more likely to reach their full potential as performance horses, breeding stock, or companions.
Reduced Veterinary Costs – Preventing serious illnesses early on can save owners from costly medical treatments.
