Regarding food intake, mares' appetites may vary during estrus. Some mares may have a temporary decrease in appetite and seem less interested in food. This change is usually mild and short-lived, and they will resume their regular feeding habits once the estrous period passes. However, it's important to monitor your mare's overall well-being and ensure she's getting adequate nutrition throughout her cycle.
In general, significant changes in appetite or any concerning behaviors should be discussed with your veterinarian to rule out any underlying health issues. Keeping track of your mare's estrous cycle and observing any changes in behavior or appetite can help you understand your mare's individual patterns and ensure her comfort and health throughout.
