52. Protein Is Not Just Protein: Protein Quality in Horse Nutrition Explained

We talk a lot about protein in horse nutrition, especially for topline, growth, milk production and gut health, but the number on the feed bag is only the starting point.

Two feeds can both say 16% protein on the bag, but they may not support your horse’s body in the same way.

In this episode of the Happy Horse Nutrition Podcast, Dr Nerida explains protein quality in horses and why the crude protein percentage on a feed bag only tells part of the story.

You’ll learn how amino acids work, why essential amino acids matter, and why lysine, methionine, threonine and the branched-chain amino acids are so important for muscle, topline, bone development, milk production, tissue repair and gut health.

Nerida also explains why protein source matters, using examples like soybean meal, whey protein, cottonseed meal, sunflower meal and forage quality, and shows how two feeds with similar crude protein levels can provide very different amino acid value to your horse.

Whether you have a growing horse, broodmare, performance horse, off-the-track Thoroughbred, senior horse, or a horse needing more topline or gut support, this episode will help you ask a better question: not just “how much protein is in this feed?”, but “is this protein good enough for the job I’m asking my horse’s body to do?”
