Pregnancy is a critical period for mares, requiring special attention to their nutritional needs. Proper feeding for pregnant mares is crucial for the health of both the mare and her developing foal. As a horse owner, understanding the essentials of equine nutrition can greatly influence the well-being of your animals.

The Importance of Proper Nutrition
During pregnancy, a mares nutritional requirements increase to support the growth and development of the foal. Adequate nutrition ensures that the mare maintains her health and produces a strong, healthy foal. Neglecting these needs can lead to complications such as poor foal growth, weak bone development, and even increased risk of disease.
It’s crucial to start focusing on nutrition from the early stages of pregnancy. According to the MSD Vet Manual, nutritional deficiencies can have long-term effects on a horse’s health, making early intervention essential.
Basic Nutritional Requirements
Feeding pregnant mares involves understanding their basic nutritional requirements. These include:
1. Energy Needs
As pregnancy progresses, the energy requirements of the mare increase. This energy is vital for maintaining the mares body condition and supporting foal development. A balanced diet with adequate calories is essential.
2. Protein
Protein is a key component in the diet of pregnant mares. It supports the growth of the foal and the development of the mares tissues. High-quality protein sources are recommended to meet these increased needs.
3. Minerals and Vitamins
Minerals such as calcium and phosphorus are critical for bone development in the foal. Additionally, vitamins like A, D, and E play important roles in immune function and overall health. Multivitamins can help ensure these requirements are met.
Feeding Guidelines
Developing a feeding plan for pregnant mares involves careful consideration of their changing needs throughout pregnancy.
1. Early Pregnancy
In the early stages, a mares diet may not differ significantly from her regular maintenance diet. However, it is important to monitor her body condition and adjust feed as necessary to prevent excessive weight gain.
2. Late Pregnancy
As the mare enters the last trimester, her nutritional needs increase significantly. This is the period of greatest foal growth, and the mare may require additional calories and nutrients to support this.
Common Nutritional Issues
Mares can face several nutritional challenges during pregnancy, including:
1. Overfeeding
Overfeeding can lead to obesity, which may cause complications during foaling. It’s important to provide balanced nutrition without excessive calorie intake.
2. Underfeeding
Insufficient nutrition can lead to poor foal development and health issues for the mare. Regular body condition scoring can help ensure mares are receiving adequate nutrition. Learn more about body condition scoring.
Supplemental Feeding
Supplements can play a role in ensuring mares receive the nutrients they need.
1. Mineral Blocks
Providing access to mineral blocks can help prevent mineral deficiencies.
2. Special Supplements
Products like zinc supplements can support various physiological functions and improve overall health.
Monitoring Health and Well-being
Regular veterinary check-ups are essential for maintaining the health of pregnant mares. These check-ups can help detect and address nutritional deficiencies early on. Additionally, observing the mare for changes in behavior or body condition can provide insights into her nutritional status.
Conclusion
Feeding pregnant mares requires attention to detail and a commitment to providing the best nutrition possible. By understanding their unique needs and adjusting their diet accordingly, horse owners can ensure the health and vitality of both the mare and her foal.
