Racehorse Cubes contain 16.9% crude protein, from quality protein sources. We include additional Lysine and Methionine, to support the increased demands of performance horses.

Quality proteins and amino acids support:

• Muscle development
• Recovery
• Topline
• Connective tissue
• Hoof quality

Lysine in particular is an essential and limiting amino acid, which must be obtained through the diet. Lysine is needed for protein synthesis, so if there isn’t enough in the diet, the horse cannot effectively synthesise the rest of the protein in their diets.

Quality, not just quantity:

Not all protein is created equal, and each feed ingredient has a different quantity AND quality. For example, grass might have a good amount of crude protein, but that protein quality could be low.

What determines protein quality?
Proteins are made up of amino acids which are like building blocks. The quality of a protein is determined by the type and number of essential amino acids that it contains and how digestible they are. Essential amino acids cannot be made or synthesised by the horse so must be provided through the diet. For a certain protein to be built, the correct amino acids must be supplied.

✅ A high-quality protein source contains the ideal ratio of essential amino acids which are easily digestible. This means that the body can then use most of those amino acids in protein synthesis.
❌ Low-quality proteins don’t offer as many essential amino acids, so there are a lot left over for the body to excrete.
