How To Calculate % Non-Structural Carbohydrates (NSC) in your horse’s diet.

When considering low-starch or low-carb nutrition options, it is important for owners to calculate NSC in their horse’s dietary regimen. With diets high in NSC linked to several digestive and metabolic disorders, it is important to feel confident in assessing the starches and sugars in your horse’s feed.

When Would You Need To Calculate NSC?

For horses with Equine Metabolic Syndrome with Insulin Dysregulation (EMS/ID) and Pituitary Pars Intermedia Dysfunction (PPID) also known as “Equine Cushing’s Disease”.

What is the maximum %NSC that should be allowed?

That depends on the severity of insulin dysregulation in the individual horse. Suggested Guidelines (*individual horses will vary) for the Maximum NSC in the Total Diet:

<10-12% for horses with Equine Metabolic Syndrome
<15% for horses with PPID “Cushings”
<12% for horses with PPID “Cushings” and insulin dysregulation (*remember that insulindysregulation can range in severity and this can change as the disease progresses)

Horse Feed With High Fat Content – The Evolving Role of Fat: The Omega-6 and Omega-3 Ratio

The use of fat in the equine diet has a long history. A very old book, Horse Secrets by A.S. Alexander, published in 1913, points out that horse traders knew back then that adding fat to the diet was beneficial for gaining weight and improving hair coat. They may not have known why it worked, but they knew that it worked!

Corn oil was an early oil source as it was available and palatable. Flax seed, boiled to both soften the husk and to eliminate anti-nutritional factors, was also used to provide both fat and protein.

The use of vegetable oil as an energy source has become standard in horse feeds. Animal fat sources, while used in early research, have pretty much been eliminated from use in horse feeds, primarily due to palatability and perception issues.

SafeChoice Horse Feeds are where good equine health starts. Each product has controlled starch levels that may help support horses who have metabolic concerns, while added-fat options improve energy and enhance performance.

From an energy standpoint, all of the common vegetable oils are very similar. More recently, considering the essential fatty acid content, particularly the Omega-6 and Omega-3 levels, has become important in selecting the oil source. As with many things, balance along with quantity is important.

As grazing herbivores, horses are accustomed to the limited amount of fat (3-5%) found in forages, particularly fresh pasture, which is high in Omega-3 fatty acids, whereas oils from grains and seeds tend to be higher in Omega-6 fatty acids.

Scientists have not yet pinpointed the ideal total dietary intake or ratio of Omega-6 and Omega-3 fatty acids for horses. Multi-species work has indicated that a ratio someplace between 2:1 and 10:1 is an acceptable Omega-6: Omega-3 ratio in a total diet. This considers the higher Omega-3 content of forages and the higher Omega-6 content of grains and some vegetable oils

Dietary supplementation with Omega-3 fatty acid sources has been shown to provide numerous benefits to horses and other animals including:

Improved skin and hair coat quality
Decreased joint pain in arthritic individuals
Reproductive benefits
Reduction in risk of gastric ulcers
Anti-inflammatory effects

Flax seed, flax oil, soy oil and fish oil (limited use due to palatability) are some of the better sources of Omega-3. Chia seed and oil may also be a useful source and other sources are becoming available.

Feeds and supplements containing added oil are generally balanced to complement the fat present in forages to deliver balanced Omega-6 and Omega-3 levels in the total diet.

Nutrient Requirements of Horses, Sixth Edition, National Research Council, National Academies Press, Washington, D.C., pages 44-53, is an excellent source of detailed information.

At Nutrena, we believe proper nutrition plays the biggest role for a lifetime of health and happiness for every horse. That’s why Nutrena horse feeds are specifically formulated for every life stage and activity level.

Grazing Muzzles – A Good Tool for Easy Keepers

Many of us are faced with the dilemma of an easy keeper – these horses seem to get fat just by looking at pasture, much less being turned out on it! We know we need to limit their intakes, but it feels cruel to lock them away from the green grass, especially when their more slender pasture-mates are able to graze for hours every day and not put on an ounce (I have a friend like that, and I work hard not to hold it against her!).

The health and well being of these easy keeping, plump horses and ponies can greatly benefit from a reduced caloric and controlled starch and sugar intake. Luckily, horse owners have a tool that can be utilized to help with this problem – grazing muzzles. Grazing muzzles allow horses to run, roam and feel like they are grazing all day, but still have their intakes reduced. The basic make up of the grazing muzzle is similar to a halter, usually with a piece of rubber affixed to it that fits over the mouth and has a small opening. This greatly reduces the amount of grass eaten and can help with weight control on those chubby horses and ponies.

Additionally, it allows the horse to get the benefits of turnout, including socialization and exercise which can help alleviate some of the boredom related issues that may be found in horses that are kept in dry lot or stalled situations (weaving, cribbing, etc.).

Some key things to consider when using a grazing muzzle:

Does your muzzle fit the horse properly? Similar to proper halter fit, the muzzle shouldn’t be too tight or too loose.
Is your fencing safe for use with a muzzle? Think about catch points like stray wires, etc. that the muzzle could get caught on. Some basic changes or repairs to fencing may be required.
After you have turned your horse out with a muzzle, monitor water intakes. Horses can drink just fine with a muzzle on, but it may take some getting used to.

With the right management, grazing muzzles can be a wonderful tool to allow your horse the freedom of the pasture without adding extra pounds.

Ration Balancers vs Regular Horse Feeds

I recently received a call from a horse owner that said she needed to put her horse on a diet. Her 1000 pound mare is a body condition score of 7. Her vet had recommended she put the mare on a ration balancer. When she priced products at the local feed store she thought that the price of a balancer was too high. Since her mare has free access to pasture, she felt that 1 pound a day of an economy feed would be good, with a few supplements. She was wonder what supplements would be best for her mare?

I told her she was on the right track to reduce the horse’s calories, but there was an easier way to put the mare on a healthy diet. I pointed out that the feed tag on the product she was feeding had a feeding rate of 0.5 pounds of feed for every 100 pounds of body weight. So, for her mare to get the proper fortification of vitamins and minerals listed on the tag, she would need 5 pounds per day.

Cutting the ration down to only 20% of the required feed rate and adding supplements could get costly, as well as establishing an imbalance in micro and macro minerals. I suggested she consider a ration balancer. The concentrated nutrient levels allow for low feeding rates. A good quality balancer will contain prebiotics and probiotics to help support nutrient digestion. They will also feature guaranteed levels of biotin to support muscle, hair coat and hoof development. In addition they will also have guaranteed levels of amino acids to support muscle maintenance and development. Not to mention that a quality balancer will also use organic trace mineral complexes to increase bioavailability and protein utilization.

When we compared the balancer to top dressing the economy feed, the balancer was a much better value on a cost per day basis. That’s why it’s always important to do the “cost per day” math, rather than getting fixated on the price tag on the bag, and remember to include the cost of supplements needed if a lower-quality, less expensive feed is being investigated.

Changing Horse Feeds – A Lot Like Horse Training

Most horse owners have a pretty steady routine when it comes to working with their horses, and that includes keeping a consistent feeding schedule and program in place, which is a good thing for the horse. However, a variety of situations, from moving to a new place, to a change in the horse’s health, can require a change in habits and possibly in diet.

Chris Cox, renowned clinician and dedicated SafeChoice® feeder, offers this advice on preparing your horse for change: “I never ask a horse to do something I haven’t prepared it to do. By the time I’m asking a horse to step on to a trailer, that horse has all the preparation it needs to do it – and by prepare I don’t mean desensitize. I don’t desensitize my horses as much as a lot people do. It’s easy to overdo it and end up dulling your horse. It’s okay for your horse to react to something, but if it is properly trained it won’t overreact.”

Chris’s training tip follows easily right in to the realm of changing your horse’s feeding program. Abrupt change, while a horse can manage and get through, isn’t the most desirable scenario. Gradual introduction of whatever is new to the feeding program, whether it is a change in the amount fed or a change to an entirely different type of feed, should be done incrementally over a period of about 7 days. This time frame allows the horse’s digestive system to adjust to the new levels of nutrients being digested, and also allows time for the sometimes-picky-eaters to realize that the new feedstuff is, in fact, OK to eat.

Preparing your horse, whether it is in feeding practices, daily schedule, or training, will set you and your horse up to make changes successfully.
