Key Nutrients Essential for Horses
Horses require a variety of nutrients in specific amounts to maintain health. These include macronutrients, micronutrients, and water. Below is a comprehensive overview:
Macronutrients
- Carbohydrates – primary energy source, mainly from forage and grains.
- Proteins – essential for tissue growth, repair, and enzyme production.
- Fats – concentrated energy source, aids in absorption of fat-soluble vitamins.
- Water – critical for all physiological functions.
Micronutrients
- Vitamins – A, D, E, K, and B-complex are vital for metabolic processes.
- Minerals – calcium, phosphorus, magnesium, potassium, sodium, selenium, zinc, copper, manganese, iodine, and iron.

Factors Influencing Nutrient Requirements
Several factors affect the specific nutrient needs of individual horses. Recognizing these factors helps tailor diets appropriately.
1. Age and Growth
- Foals, weanlings, and young growing horses have higher requirements for proteins, minerals (especially calcium and phosphorus), and energy to support rapid growth.
- Mature horses have stable nutrient needs, primarily for maintenance.
2. Reproductive Status
- Pregnant and lactating mares require increased energy, protein, and minerals.
- Nutritional demands peak during late pregnancy and early lactation.
3. Activity Level
- Working horses, racehorses, and performance animals need higher caloric intake and balanced nutrients to sustain activity.
- Sedentary or companion horses require fewer nutrients.
4. Health and Conditions
- Horses with health issues or recovering from illness may need specialized diets.
- Age-related conditions like dental problems may influence feed intake and nutrient absorption.
5. Environment and Management
- Horses grazing on lush pasture might meet many of their needs naturally.
- Stored forages or concentrates may require supplementation to fulfill deficiencies.

Recommended Nutrient Levels: Insights from the Horses Nutrient Requirements PDF
The horses nutrient requirements PDF typically includes detailed tables specifying daily nutrient intake recommendations based on body weight, activity, and life stage. While figures vary, some general guidelines are:
Energy
- Maintained horses: approximately 15-20 Mcal of metabolizable energy per day.
- Working or lactating mares: higher, often 25-30 Mcal/day.
Proteins
- Mature horses: 8-12% crude protein in the diet.
- Growing horses: up to 14-16% protein.
Minerals
- Calcium: 0.6-1.0% of diet dry matter.
- Phosphorus: 0.3-0.6%.
- Salt (NaCl): 0.5-1% of diet dry matter.
Vitamins
- Vitamin A, D, and E levels should meet or exceed minimum recommended levels, often supplied via forage or supplements.

Utilizing the Nutrient Requirements of Horses PDF for Proper Feeding
The PDF resource is invaluable for formulating balanced diets. Here are ways to effectively utilize such documents:
- Assess Current Diet: Compare the nutrient content of available feeds with the recommended levels.
- Calculate Rations: Use tables to determine appropriate feed quantities to meet daily requirements.
- Identify Deficiencies or Excesses: Adjust feed ingredients to correct imbalances.
- Plan for Special Needs: Tailor diets for foals, pregnant mares, or performance horses based on specific guidelines.
Note: Always consider individual variation and consult with an equine nutritionist when using PDFs or other technical resources.

Common Feeding Strategies Based on Nutrient Requirements
Effective feeding strategies incorporate the principles outlined in the nutrient requirements of horses PDF:
1. Forage-Based Diets
- The foundation of most horse diets, providing fiber, vitamins, and minerals.
- Quality hay or pasture should fulfill most nutrient needs.
2. Concentrate Feeds
- Grains and commercial concentrates supply additional energy and nutrients for active horses.
- Should be balanced to complement forage intake.
3. Supplementation
- Mineral and vitamin supplements may be necessary when forage alone does not meet requirements.
- Use based on forage analysis and individual horse needs.
4. Water Access
- Ensure unlimited access to clean, fresh water at all times.

Common Mistakes and How to Avoid Them
Understanding the nutrient requirements of horses PDF helps prevent nutritional errors:
- Overfeeding energy: Leads to obesity and related health issues.
- Underfeeding nutrients: Causes deficiencies affecting growth, reproduction, and performance.
- Ignoring forage quality: Can result in imbalanced diets despite adequate total feed intake.
- Not adjusting diets for life stage or activity: May compromise health or performance.
