Mares’ milk composition as related to “foal heat” scours.

The research article tries to understand the condition known as “foal heat” scours, which affects young foals during a mare’s first estrum, with a focus on the changes in the composition of mare’s milk during this period.

Introduction to “Foal Heat” Scours

• “Foal heat” scours is a condition that affects young foals, usually during a mare’s first estrum, around 9 days post-partum i.e., after the birth of the foal.
• Several potential causes for this condition have been suggested over time. These include changes in the composition of the mare’s milk during the ‘heat’ period, the foal’s ingestion of genital discharge, ingestion of foreign matter like straw, feces, grass, and overloading of the foal’s digestive tract.

Objective of the Study

• The specific aim of this research was to explore the role of changes in milk composition during the mare’s first estrum in the onset of “foal heat” scours. By studying the milk’s components at 9 days post-partum, the researchers aimed to better understand if and how these changes contribute to the condition.

Experimental Procedure

• The experiment was conducted using six Quarter Horse mares, ages ranging from 3 to 7 years. These mares had zero to three lactations i.e., they have gone through the lactation process up to three times prior to this study. The use of mares with varying lactation history provided a dynamic range to the data, increasing the validity of the findings.
