Does My Horse Need a Diet or Exercise Change?

I recently taught an Equine Nutrition class to a group of seniors at an area college.  Our focus for the classroom lecture was dietary assessment by body condition scoring, weight and topline evaluation.   After the lecture I conducted a lab to apply hands on practice of what we had just reviewed.

One of the students asked if we could evaluate her horse during the lab session. The evaluation proved to be a classroom classic. The horse was a 4 year old Warmblood gelding. He was 17.1 hands and 1350 pounds. The horse at first glance appeared to be round and in good flesh, but as I ran my hands over his withers and back you could feel a lack of muscle and coverage.hand feeding red size

I asked the student what the horse’s current diet consisted of, she replied 20 pounds of first cutting hay per day and 8 pounds of locally grown oats. The calorie content of the diet appeared to be sufficient, however the amino acid balance was lacking. The student also mentioned she had her saddle recently refitted and the chiropractor out because the horse was having back issues.

With the move to college, the horse’s workload had increased and the need for additional fortification was obvious. I suggested that the student purchase a ration balancer to balance the needs of the young horse’s diet and help replenish his topline.

One of the students in the lab then challenged my recommendation.  She stated that she was an Equine Physiology major and felt my diagnosis was incorrect. She felt that by working the horse in a more collected manner, engaging his hind quarters and coming up under him would help to strengthen and develop his topline. She thought he looked fat and did not need to change his diet.

I went on to explain that the horse’s current diet was similar to a young child that would be on a straight rice diet, which is deficient in amino acids. You would see a round abdomen, but lack of muscle mass. If that child were getting ready to compete in a marathon, I doubt running extra laps would increase muscle mass, unless we supplemented the diet properly.

Again, your horse will tell you what is lacking in his diet, if you just take the time to look.

Feeding the Maintenance Horse

Vitamin in half
Feeding below the recommended amount of a particular horse feed, is analogous to only taking half of your daily vitamin.

I am fortunate in my job to speak with horse owners face-to-face on a frequent basis. During these conversations, I enjoy hearing about the horses they own and how great their horse’s look and perform.

Occasionally, I will hear someone mention that their horse looks great on hay alone and they only feed a ‘handful’ of grain in the morning and night, just for the vitamins and minerals.

I delicately point out that the analogous human activity would be chopping your daily vitamin into pieces and taking a fraction of one a day. This is an opportunity to discuss feeding rate, calorie requirements, muscle and hair coat quality, and making sure owners have selected the right feed for their horse.

In many of these instances, the horse in question is an adult in good body condition, on a good quality forage and light work load; in other words, a horse at maintenance activity level.  Even though this horse may be able to keep a good body condition score, without balanced nutrition, they will exhibit less-than-ideal muscling, hair coat and hoof quality.

A well-intentioned owner of this kind of horse might feel they need to provide some form of nutrition supplementation to their hay, as they should, but may not fully understand what is needed or the appropriate quantities. Feed, being as complicated as it can be, is often misinterpreted and either under or over fed. Here’s where we can help!

If a maintenance horse is in good or better-than-good body condition (a 6+) from their hay or pasture alone, they really don’t need more calories in the diet. But they do need something to fill in the gaps that the hay or pasture is not providing. These include vitamins, minerals and quality proteins (amino acids) their body needs for normal tissue repair, hair growth and muscle maintenance.

For this horse, a ration balancer is the ideal solution. A ration balancer (sometimes called diet balancer) is a concentrated form of feed without the energy provided by fats, fibers, starch and sugar of a regular feed. Ration balancers tend to have higher guaranteed levels of nutrients, but significantly lower feeding rates. Don’t panic! A protein level of 30% with a feeding rate of 2 pounds per day means your horse gets 0.6 pounds of protein. Compare that to feeding 6 pounds of a 14% regular feed = 0.84 pounds of protein per day. When you do the math, it’s really in line with a “normal” diet.

If this same horse would be slightly below ideal body condition, a feed designed to be fed to maintenance horses would be appropriate for calories and the balance of other nutrients. Be sure to follow the feeding rates and keep a close eye on how your horse responds to the feed, as you may need to adjust within the feeding rate guidelines.

When it comes to calorie management of the maintenance-level activity horse, remember to watch out for those treats, too. Calorie levels can vary widely so all the work you’re doing to manage intake with the feed scoop can easily be washed away with an indulgence in treats!

Feeding a horse at a maintenance activity level doesn’t have to be complicated. With a few pieces of information and the right feed, your horse can look and feel their best, even if they aren’t heading for the show pen.
