36: 5 Ways to Help Hormonal Mares Naturally

Healing Horses with Elisha

This week, we are shifting our focus to hormones in mares.

Many horse owners are eager to learn how to manage hormonal mares and better understand their behavior. While the most intense symptoms of hormone changes tend to surface in spring, chronic issues can persist year-round, making them challenging to handle, as hormonal imbalances can significantly alter their brain chemistry, behavior, and well-being.

As most women know, hormones are powerful and can cause severe symptoms. Unfortunately, horses cannot easily communicate what they are experiencing. So, today, I share tips on approaching hormonal issues with mares naturally and holistically.

Introduction to Hormonal Imbalances in Horses

Hormonal imbalances in horses, particularly mares and geldings, have become normalized in the industry. That has led to a lack of awareness about healthy hormone levels. The primary causes of hormone imbalances are stress, nutrient deficiencies, and toxicity, which disrupt homeostasis in the body.

Seasonal Hormonal Changes

In spring, increased daylight triggers hormonal changes in mares. Their eyes absorb more light, activating the endocrine system, including the hypothalamus and pituitary gland. The hypothalamus, known as the master gland, orchestrates these changes by stimulating various hormones in response to environmental factors such as temperature, fluid balance, hunger, and stress.

Hypothalamus and Pituitary Gland Interaction

The hypothalamus links the nervous and endocrine systems, receiving environmental information and eliciting a response by stimulating the pituitary gland with neural hormones. This complex interaction prepares mares for reproduction, producing follicle-stimulating and luteinizing hormones for estrogen and progesterone production in the ovaries.

Estrus Cycle and Hormonal Symptoms

A healthy mare experiences a 21-day estrus cycle, with ovulation around day 16 and heat lasting 4-6 days. However, many mares suffer from hormonal imbalances, leading to chronic heat cycles and symptoms such as uterine pain, colic, sweating, frequent urination, back pain, and general stiffness. These symptoms often go unrecognized as hormonal issues.

Behavioral and Emotional Impact

Hormonal imbalances also affect the behavior of mares, causing agitation, anger, depression, fatigue, and anxiety. That can impact their ability to cooperate with humans, making them unsafe and hard to handle. Recognizing and addressing the imbalances through nutrition and lifestyle adjustments can significantly improve their behavior and overall well-being.

Conventional and Holistic Approaches

While hormone replacement therapies are commonplace, they come with many side effects, including weight gain, uterine infections, and risks to human handlers. Medications like synthetic progesterone and medroxyprogesterone suppress estrus, but their risks often outweigh the benefits. A holistic approach focusing on diet, nutrition, and natural remedies is better for long-lasting results.

The Role of Stress and Nutrition

Stress significantly impacts hormonal balance, as elevated cortisol and insulin levels disrupt the physical equilibrium. Nutrient deficiencies, particularly vitamin B6 and magnesium, contribute to hormonal issues. Essential fatty acids, calcium, and Vitamin B12 will also support hormone regulation and overall health.

Protein and Alfalfa

Excessive protein intake can lead to behavioral and anxiety problems in horses. While protein is essential, horses do not require as much as some owners might think. Be cautious with alfalfa, a high-protein forage, and ensure it is relevant and appropriate for your horse.

Commercial Feeds and Hormone Impact

Commercial feeds can contain various ingredients that affect hormone levels in horses. Some ingredients, like soy, have phytoestrogens and preservatives that interfere with endocrine pathways. Adjusting or removing commercial feeds from their diet can significantly improve their behavior, health, and hormone balance.

Managing Stress Levels

Chronic stress in horses can imbalance hormones like estrogen, progesterone, testosterone, adrenaline, and cortisol. That is why owners should minimize their stress levels and become aware of any stress-related signals. Movement is also essential for proper hormone metabolism and detoxification.

Importance of Movement

Movement is vital for the equine metabolism, circulation, and lymphatic system. Confinement and lack of social interaction can lead to health issues that no amount of nutrition or supplements can fix. Ensuring horses have regular exercise and playtime with other horses is crucial for their overall health.

Liver and Hindgut Health

Liver and microbiome health are the keys to proper hormone metabolism. Horses with liver toxicity or an imbalanced microbiome cannot metabolize hormones effectively. So, owners must consider the overall health profile of their horses, including signs of chronic infections or skin conditions, as part of managing hormone regulation.

Horse-Human Relationship

Horses can mirror the hormonal imbalances and stress levels of their owners. If an owner has high stress or hormonal issues, it can affect the health of their horses. When owners manage their health and stress levels, it can positively impact the health of their horses.

Practical Steps for Managing Hormonal Mares

To manage hormonal mares, consider these five steps:

1. Dietary Adjustments: Monitor sugar andalfalfa intake, as excess alfalfa can overstimulate the pituitary gland and disrupt the microbiome, contributing to hormonal issues.
2. Stress Reduction: Implement strategies to minimize stress, especially in competitive horses.
3. Nutritional Support: Ensure adequate intake of key nutrients like vitamin B6, magnesium, essential fatty acids, calcium, and B12.
4. Liver Health: Support liver function through a balanced diet and supplements to improve hormone metabolism.
5. Holistic Management: Adopt a holistic approach to address underlying causes of hormonal imbalances, focusing on diet, lifestyle, and natural remedies.
