Threonine and its roles:

  • Muscle anabolism
  • Collagen formation (tendon, bones,…)
  • Teeth formation
  • Essential for growth

Threonine is an essential amino acid for horses. Athletic horses or horses with a high rate of metabolism need more than sedentary horses.

The estimated needs for threonine are 0.45 g per kg of metabolic weight and per day.

The metabolic weight corresponds to the horse's weight to the power of 0.75: for example a horse of 450 kg:  450 0.75 = 98 kg of metabolic weight; such a horse will need 43.6 g of this amino acid per day from its dietary sources.
