Supplements, Supplements! Does my horse need them?

Just like us, horses get most of their nutrients from their diet, but if their diet has been affected by drought, poor forage, or they don't have access to pasture they may need support in getting some of the required nutrients for normal body functions.

So, when you are asking the question, does my horse need a supplement? First ask yourself, what is my goal? What do I think they are lacking and does their current diet support that? More times than not, I think we over supplement with synthetic or poor quality supplements. My approach has always been a more natural approach while still trying to not break the bank because your horse utilizes natural forms much better than synthetic.

For example, the last 2 years have been rough on our pastures as we haven't had the moisture that we usually get and had to cut back on pasture time for our horses. While we still provided hay, as we all know, once forage is cut, many fresh nutrients decline, like Vitamin E. Vitamin E is found in fresh grass so when you don't have access to pasture or the grass is dormant, look for a natural Vitamin E source. This is a great article to help you out!

Does My Horse Need a Vitamin E Supplement? - Kentucky Equine Research Although young animals begin to produce their own antibodies as they develop, horses never outgrow their need for vitamin E. For mature horses in a schedule of training and performance, vitamin E's role as an antioxidant is important in protecting tissues and cells from degradation by free radicals.

Kentucky Derby is Saturday!! Who you betting on?!🐎

Merry Christmas!! May you all have a wonderful day and a hopeful and happy New Year!!

Colorado seems to be the closest to us in MT, but if you are traveling, please take precautions 🙏❤️🐴

Thank you so much to all of my clients!

I am so very blessed honored to have been a part of your horse's wellness journey this year.
I learn so much with every session and I hope you all know how very special each of your horses are to me.

I wish you all the happiest Thanksgiving! ❤️🐴

It's that time of year! Horses got there teeth done🙌🥳 Thank you Shaylee Rae Mills for getting this set up 🐎

Coming into cooler weather, many horse owners think that the risk of their horse foundering has passed, but this study shows some interesting findings that support the need to STILL watch your horse and monitor their pasture intake if they are at risk or have foundered before.

Because it is that season, it is time to bring back this post on horse pastures and nonstructural carbohydrates, specifically as they relate to the beginning and end of a grazing season. Let’s begin by breaking this down by each topic before we add them all together!

Nonstructural carbohydrates, often abbreviated as NSCs, are comprised of water soluble carbohydrates (simple sugars and fructans) and starch. This class of carbohydrates is an important source of energy for the horse and they are digested and absorbed in the foregut, leading to an increase in blood glucose and insulin. As a result, high levels of NSCs in the diet can be an issue for horses with metabolic concerns specifically related to insulin dysregulation such as equine metabolic syndrome (EMS), Cushing’s (PPID), and laminitis/founder. While NSCs can be more consistent and documented in manufactured concentrates, more variation is observed in pasture or hay due to outside factors such as plant maturity, time of day, and weather conditions.

In pasture plants, NSCs are produced via photosynthesis, a process in which sunlight, water, and carbon dioxide generate glucose and oxygen. A separate but complementary process known as respiration is responsible for breaking down the glucose created during photosynthesis and releasing that energy for cellular use. As a result, increased photosynthesis leads to an accumulation of NSCs and increased cellular respiration leads to a decrease of NSCs. There are many weather conditions that can alter the balance between these processes in plants.

So how are these two factors connected to frost and the swing in temperatures observed in the spring and fall when horses are either being introduced to or removed from pasture? Well, when temperatures fall below 40°F, the enzymes involved in cellular respiration become significantly less active. And when temperatures fall below freezing, the enzymes can become denatured, stopping respiration altogether. This means low temperatures can lead to an accumulation of NSCs in the forage which can be problematic for grazing horses.

💡 This is exactly the area I’m exploring in my current research. We know that nonstructural carbohydrate levels tend to rise - and often remain elevated - after a frost, but we lack solid, data-driven numbers to confirm how much they change and for how long. That missing information makes it hard to create precise grazing recommendations or confidently manage horses with metabolic concerns. I’m collecting forage samples immediately following frost and over the subsequent days to track ESC, WSC, and starch changes over time, but sending those samples in for lab analysis requires funding. If you’d like to help fill this knowledge gap and support research that could directly improve pasture management and horse health, even a small contribution, comment, or share makes a real difference:

This also means it is important to look at the nightly lows, and if these temperatures are sustained for more than a few hours, change your management practices accordingly, especially for glucose-sensitive horses. Furthermore, a hard frost occurs when temperatures drop below 28°F for more than four consecutive hours and will not only result in NSC accumulation but also marks the end of the growing season. While current recommendations allow grazing to resume 7 days following a hard frost, pastures require a minimum height of 3” to 4” going into the winter to support pasture productivity the following grazing season. Since grasses will no longer grow after a hard frost, continuing to graze can put undue stress on the pasture.

Additionally, sudden changes in the diet that would occur from removing horses from pasture abruptly, keeping horses on dried forage for 7 days, and then reintroducing horses to pasture, could lead to digestive upset or other health problems and the process will be time intensive for owners. When shifting the diet, even between different forages, it is critical to plan intentional transitions that allow the gut microbiota to sufficiently adapt. While the transition back to pasture can be accelerated in the fall compared to beginning grazing in the spring, it should still be done with care.

I hope this information is helpful as you make decisions on horse management and grazing this season!
