International curves are published for different equine breeds to establish the average speed in growth and development. This helps the breeder identify foals that are growing very quickly and those that are at higher risk of develop orthopedic disease. This also allows a breeder to evaluate if a foal is lagging behind the growth curve and thus ensure that the optimal mature height is reached.

Horse1 weighs your foal with a correctly calibrated equine scale and then uses Gro Trac, the specialized software developed by Kentucky Equine Research ( to calculate the growth curves and compare then with the published breed curve.

If the colt doesn’t have the necessary fat reserves, it has greater risk of not surviving the common diseases such as diarrhea or even a simple cold. If it is born disproportionately large, or grows too fast, there is a higher risk of pathologies related to growth. If you evaluate the true growth curve and compare it with the publishd breed curve, you can quickly see if the colt is growing properly and how it compares in size with other foals of the same breed. Our system also calculates the average daily weight gain to ensure that its growth is constant and continuous, avoiding the variations that can cause growth issues.

This evaluation can also help to quickly identify if the foal reduces its growth and development. This is typical for example, during weaning or in certain social situations with more aggressive pasture mates.

We recommend measuring the foals from birth through to 18 months of age, every 6 weeks.
