Support your breeding stock's nutritional requirements with GroStance

Did you know that breeding stock have higher nutritional requirements?

Breeding horses, including pregnant and lactating mares, stallions plus young and growing horses all have greater nutritional requirements than resting horses.  They require different levels of vitamins, minerals and amino acids.  Amino acids are required for growth, development, protein production and muscle repair. Horse's bodies manufacture 12 of the 22 required amino acids, so it is important to provide the other 10 'essential' amino acids through their feed.

"I purchased a three year old Brumby and wanted to provide him with feed and supplements that would encourage him to grow strong and healthy. Since adding GroStance to his daily feed my Brumby has developed beautifully. He now stands at 15hh and is still growing. I will continue to add GroStance to his feed as the benefits are unmistakable." - Emma
