What is the name of the first milk produced by a mare after foaling that provides antibodies for the foal?

Colostrum is the correct term for the first milk produced by a mare after she has given birth. It is critical for the foal's health, as it is rich in antibodies, providing essential immunity to the newborn. These antibodies play a vital role in helping the foal fend off infections and diseases in the early days of life when its immune system is still developing.

This initial milk is produced in the first 24 hours post-foaling and has a high concentration of proteins, vitamins, and minerals, making it incredibly nutrient-dense for the foal. The timing of colostrum ingestion is crucial; foals need to consume it within the first few hours to maximize the absorption of these vital antibodies.

In contrast, the other terms like "foal milk," "first milk," and "nutrition milk" are not standard terminologies used in equine care and do not specifically denote the unique properties and importance of colostrum in the context of a mare and her foal.
