[Nutrition of horses: digestion, energy and protein evaluation and nutritional standards].

The research article focuses on horse nutrition, specifically the ideal balance of energy, proteins, and nutrients to maintain health and prevent disease. It explores how different food components are digested throughout the gastrointestinal tract and introduces recent advancements in net energy and digestible protein evaluation systems for horse feeds.

Digestion in the Equine Gastrointestinal Tract

The authors elaborate on the process of how horses digest different nutritional components of their diet:

• Carbohydrates: These are vital sources of energy for horses. The article discusses the digestion process of carbohydrates, which primarily occurs in the hindgut, attributable to microbial fermentation.
• Fats: While horses can digest small amounts of fats, their natural diet does not consist of high-fat content. This paper presents information on how horses absorb and utilize fats from their diet.
• Proteins: Protein digestion mainly happens through microbial fermentation in the horse’s hindgut. The authors illustrate the pathway and functions of dietary proteins in equine nutrition.

Energy and Protein Evaluation Systems

The researchers introduced recent advancements in net energy and digestible protein evaluation systems. These systems help to quantify nutrients in horse feeds:

• Net Energy Evaluation: This system allows for a better assessment of the amount of energy a horse can derive from a certain feed, helping to tailor the diet according to the energy needs of the horse.
• Digestible Protein Evaluation: Evaluating the level of digestible protein in horse feeds helps to meet the specific protein requirements of different horses, thus ensuring a balanced diet.

Nutritional Standards for Horses

The paper presents guidelines on the energy and protein requirements of horses, emphasizing the importance of appropriate nutrition in maintaining equine health and preventing diseases. The requirements depend on several factors, including the horse’s age, activity level, breed, and overall health status.

Prevention of Nutritional Problems

Emphasizing the significance of correctly composed and proportioned horse ration, the article points out that many health issues or diseases can be warded off by attending to these feeding guidelines. Implying that the adherence to correct composition and feeding regimens can significantly impact the overall well-being of horses.
