Optimal growth Ideally, you should feed young horses to grow at a moderate, steady rate. The National Resource Council (NRC) recommends rates of average daily gain for horses.
Recommended average daily gain values for horses of different mature body weights range from 0.28 to 0.39 percent and 0.15 to 0.21 percent of the horse's body weight for weaklings and yearlings, respectively. Maximum growth Feeding a young horse for a maximum growth rate is undesirable because bone hardening lags greatly behind bone lengthening.
Ideally, young horses should gain weight at a rate that their developing bones can easily support. Growing bones don’t have the strength to support rapid weight gain from overfeeding, especially energy.
Rapid weight gain can also make other skeletal anomalies worse. In these cases the risk of developmental orthopedic disorders (DOD) and unsoundness increases.
For example, switching an underfed, slow growing horse to a good diet that allows quick growth, increases the risk of DOD. Fat should cover the top to ½ of the ribs below the flat of the back.
Risk of defective bone and related tissue formation increases with one of more of the following: Always provide horses free access to fresh, clean water.
Young, growing horses need a diet ratio of Ca to P between 1 and 1 and 3 to 1. Maximizing forage intake will mimic natural feeding behavior and bring about gut health.
Thus, don’t rely on pasture alone to provide your young horse with all the nutrients they need. Concentrates A horse’s ability to efficiently use forage develops over time.
Only feed enough concentrates to achieve the desired growth rate and maintain a moderate body condition score. Always consider the expected feed intake when calculating your horse’s daily ration.

Maximizing forage intake will mimic natural feeding behavior and bring about gut health. Nutrition is important for growing horses between weaning and 2 years of age.
During this time, bone formation and size greatly increase as well as muscle mass. Thus, these horses need the proper amount and balance of energy and nutrients in their ration.
Growing youngsters are not always easy to keep looking at their best but, with a little care and attention to their diet and management, we can ensure they look well, while still supporting steady, even growth. Their diet is generally, therefore, deficient in nutrients, including all-important protein, which supplies key essential amino acids for muscle and tissue development.
As a result, these youngsters often have a weak top line and poor muscle development yet many may be overweight and, depending on forage quality, may have a “hay belly” appearance. The diet must supply the essential quality protein and micronutrients, to support growth, while meeting calorie requirements to promote or maintain condition.
The key to achieving excellent physique is to provide the correct nutritional balance to support growth and development while meeting an individual’s calorie requirements. The quality of the forage available (grass, hay or haulage) will determine the amount of additional calories required in the diet.
For those holding weight and condition well on a forage-only diet, Stud Balancer is ideal for providing essential supporting nutrients without additional calories. Prep Mix, Prep-Ease or Yearling Cubes are ideal for those prone to excitability as they non-heating with a good oil content for slow release energy and a shiny coat.
Ensure that the diet is fully balanced and meeting nutritional requirements, aiming for muscle tone, top line and ribs that you may not see but can certainly feel. Weigh tape on a weekly or fortnightly basis and make a note of body weight to spot any upward or downward trends.
You want your youngsters to achieve their maximum height and full athletic potential–but you don’t want to overdo the nutritional support and create all sorts of growth-related problems. Horses achieve about 90% of their full height by 12 to 15 months of age as well as 95% of their mature bone length and 70% of their adult weight.
Because the growth rate has slowed there is less risk of developmental joint problems; if your yearling hasn’t developed them by now it’s likely that with continuing correct nutritional support he’s out of the woods. Studies have confirmed that a fast growth rate will not increase the mature size of a horse, and it puts undue strain on developing bones and joints.
As the young horse grows and transitions from weaning to yearling, nutritional demands continue changing, although not quite as dramatically. The rate of growth begins to slow down, but with a larger body mass to maintain, the nutritional requirements are still greater than they will be at maturity.
However, as they grow through their first year, they will begin to look rougher, become lanky and often lose muscle development over their towlines if they are fed like mature horses. Yearlings in such condition are showing that they aren’t receiving proper nutritional support for growth.
April 3, 2012March 20, 2018By Dr. Peter Huntington Young horses need the best -quality feeds to meet their requirements for growth and free exercise. Crushed maize (corn), rice, and barley are other grains that are good sources of energy for the growing horse.
Young green grass/clover pasture contains 15–20% crude protein, but this amount falls rapidly as the plants begin flowering and go to seed. Linseed meal is relatively low in lysine and is not a good source of protein for growing horses, although its high oil content will produce a bloom on the coat.
Urinalysis can be used to assess the calcium status of young horses, or the calcium/phosphorus balance of the ration can be HTTP://www.equinews.com/article/providing-dietary-calcium-and-phosphorus-horsesalyzed by an equine nutritionist. Trace minerals such as copper, zinc, manganese, and selenium are important components in the diet for most growing horses, and are supplied in the right quantities and ratios in commercial feeds formulated for young horses.
Therefore, you must use good-quality chaff or hay to maximize the utilization of the fibrous feed in meeting the energy requirements and so decrease the amount of starch the weaning has to be fed. Lucerne (alfalfa) or clover hay will also supply protein and calcium as well as fiber, so they are preferred for growing horses and should be fed on demand.
To see the wind's power, the rain's cleansing, and the sun's radiant life, one need only to look at the horse. I fed mine Strategy by Purina plus free choice hay.
I think the thing you want to look for in a yearling ration is proper balance of protein and fat along with proper calcium to phosphorous ratio. There is a link between improper protein and fat balance and orthopedic issues such as bone chips.
Try to find a feed that derives most of its calories from fiber as this is the most useful and easily digestible energy source for your horse. If most calories come from starch, skip that feed and move on.
Good quality forage is the most important thing. I would suggest you go to a good feed store that carries a variety of brands and ask a lot of questions.
To see the wind's power, the rain's cleansing, and the sun's radiant life, one need only to look at the horse. I couldn't find a list of ingredients though, so I'm not sure if this is a high-glycemic feed or not.
I would still provide some kind of ration balancer as a to[p dress to ensure proper salt intake. Purina has some good charts and articles as does Master feeds.
