Why Should I Feed My Horse Amino Acids?

What are the signs of protein deficiency in my horse?

  • Poor coat quality: A dull or rough coat that lacks shine 
  • Slow hoof growth: Cracked or brittle hooves 
  • Loss of muscle mass: Reduced muscle mass 
  • Poor growth: Slower than average daily gain 
  • Reduced appetite: Picky eaters, wasting feed, not cleaning up a reasonable ration
  • Slow recovery from illness: Impaired immunity 
  • Poor performance: Fatigue and loss of performance 
  • Low milk production: In lactating mares

Protein is made up of amino acids, and the quality of the protein depends on the combination and concentration of those amino acids. Some amino acids are essential, meaning the horse can't produce them on its own and must get them from its diet. Limiting amino acids are those that are in short supply and can restrict the horse's ability to produce protein. For horses, the limiting amino acids are lysine, threonine, and methionine.

Why are amino acids important?

Feeding amino acids to horses is important because they are the building blocks of protein synthesis, which is essential for various bodily functions in horses, including muscle development, tissue repair, immune system function, hormone production, and overall growth. Many amino acids are only available to horses through dietary supplementation.

Why is it important to feed a variety of amino acids, and not just one, like Lysine?

Amino acids are the basic units that link together to form a protein chain during protein synthesis. Several different amino acids are important in protein synthesis because they act as the building blocks for proteins, with each unique amino acid contributing to the protein's final structure and function, meaning the variety of amino acids allows for a wide range of protein structures and therefore diverse biological roles within the body; essentially, different amino acids with different chemical properties are needed to create complex proteins that can perform specialized tasks within the body.

What is protein synthesis and why is it important?

Protein synthesis is crucial because it is the process by which cells create proteins, which are the building blocks of all living organisms, performing vital functions like structural support, enzyme catalysis, hormone signaling, and immune response, essentially enabling cells to function and carry out their necessary tasks for life. Without protein synthesis, cells cannot maintain their structure or perform essential biological processes.
