Why are Trace Minerals Good for Horses?

Trace minerals have a significantly large impact on the overall health of your horse. Feeding them in proper amounts AND ratios is key to helping your horse be as happy and healthy as possible!

What Are Trace Minerals?

Trace minerals are required by animals in small amounts, usually only milligrams per day. The most common trace minerals include: zinc, copper, cobalt, manganese, iron, iodine and selenium. The organic trace mineral complexes used in all premium Nutrena® horse feeds, including both SafeChoice® and ProForce® are absorbed into the body better than conventional trace minerals because they are chelated. Effectively meaning they are bound one-to-one with an amino acid. Better absorption means an optimal quantity is formulated into the feeds, reducing the amount of wasted minerals.

What Are The Benefits Of Organic Trace Minerals In Feeds?

A diet fully fortified with organic trace minerals provides the following benefits for horses:

  1. Improved hair, coat, skin and hoof quality/hoof wall integrity
  2. Formation, maintenance and repair of joint cartilage
  3. Proper muscle and bone development
  4. Increased immune response to help remove free radicals and protect cell membranes
  5. Proper fertility function including milk production and fetal development

Deficiency can result in immune depression, reproductive failure and poor hair coat. Outward signs of deficiency are difficult to spot. Organic trace minerals help give your horse a lifetime of improved performance, safety and nutrition from every feeding.

Equine New Year’s Resolutions

It’s that time of year when everyone seems to be resolving to do things differently. Whatever that means to you, we are putting a horsey spin on resolutions as they relate to what we do with our equine partners and our activities around the barn. Here are some resolutions to consider if you’re trying to change things up for the New Year:

Commit to a barn safety evaluation

Look around and identify things that need repair such as loose boards, nails protruding, broken crossties, or loose electrical outlets. This is also a great time to revisit or create your fire evacuation plan. Make sure you have extinguishers around in key areas and that they are functioning. You don’t want to discover your fire extinguisher is no longer working when you need it most.

Focus on nutrition

Take a close look at your horse and determine if they require some extra weight, need to lose a few pounds (like many of us this time of year!) or look just right. Also check to see how your horse’s topline looks and utilize the TES tool to review how it should look. This is a chance to re-evaluate your nutrition program.

Work on an emergency fund

“Horses are extremely predictable and always make good decisions”, said no one ever. We all know that there is a high probability our horses will get injured or sick at some point in their lives. And often it’s on a weekend or holiday that incurs emergency vet fees. If you can put away some extra funds to build up savings in case disaster strikes when you least expect it, it will help soften the economic blow.    

Clean out your trailer, tack box or your mobile tack room (i.e. your truck or car)

“A place for everything and everything in its place” is a great mantra to start the New Year off right. There is nothing more satisfying than opening a neatly organized tack box or getting rid of the extra horsehair in your vehicle.

Enjoy your time together

No matter what you do with your horse, commit to spending some quality time with them every day. Riding, groundwork or even just some grooming to see what lurks under that winter blanket or shaggy coat will strengthen your bond.

Ready to make this the year you ensure your horse is getting the optimum nutrition at feeding time, every time? Find the perfect feed formulated specifically for horse’s needs with our Feed Selector Tool.

Performance Horses and Muscle Recovery

Stevi Hillman barrel racing representing Performance Horses and Muscle Recovery

In various disciplines speed, strength, collection and stamina all play into the difference between earning a big paycheck and awards or going home empty handed. Performance horses need to be able to come out of the stall ready to win, whether it’s the first day of the event or the last. Like their human athlete counterparts, a solid nutrition plan is the fuel that allows performance horses to compete and perform at their highest level. With Rebound Technology™, recovery isn’t an afterthought, the horse is always being fed for optimal performance.

Enhancing Performance Horse Recovery with Rebound Technology™

Rebound Technology™ is a unique, proprietary blend of research-backed chromium and branched chain amino acids (BCAAs) to support exercise recovery. When performance horses have the right nutrition, they are more able to quickly return to peak performance after strenuous training sessions and/or competitions.  Each time an equine athlete competes or performs there is an opportunity to increase its value, that of future offspring or help a rider achieve his or her goals. That’s why avoiding muscle fatigue and giving horses the ability to rebound from exercise and efficiently train for performance activities is a high priority for horse owners and trainers alike.

What Happens When Performance Horses Exercise

When horses exercise, they experience an increased cortisol level, reduced muscle glycogen, increased Serum Amyloid A (normal inflammation), increased heart rate, reduced blood sugar and reduced plasma BCAAs. Three major factors in improving athletic performance in the horse are muscle development, muscle recovery and glycogen availability. Faster glycogen replenishment in the horse could lead to increased muscular performance.

As horses work, ATP or energy enables their muscle fibers to quickly contract and relax. Each muscle cell contains only enough ATP for a few contractions, which means horses must continuously resynthesize ATP during exercise primarily via stored glycogen. The more glucose we can make available to the cells in the performance horse, the better able they are to quickly replenish glycogen. The unique ingredient combination found in Rebound Technology™ optimizes the opportunity for these glycogen and glucose levels to rebound after work.

The essential BCAAs leucine, isoleucine and valine help to decrease muscle fatigue and improve muscle recovery19. Research with BCAAs has demonstrated that leucine infusion along with glucose infusion appears to increase whole body glucose availability, potentially increasing glycogen synthesis in horses1. Oral leucine supplementation has shown increased markers associated with protein synthesis in the post-exercised performance horse. Providing an increased rate of protein synthesis would increase both muscle mass and muscle recovery, both of which may improve athletic performance. In humans, BCAA supplementation prior to exercise appeared to reduce delayed onset muscle soreness and muscle fatigue, increased insulin response along with increased post-exercise rates of glycogen synthesis 5,7,8,9,10. Increased availability of amino acids and glucose demonstrated in research shows an improvement not only in protein synthesis, but also a decrease in protein breakdown19. 

Chromium’s Role in Recovery and Protein Synthesis

Recently FDA and AAFCO approved chromium propionate as a feed ingredient. Found in Rebound Technology™, it supports glucose getting to the cells where it’s needed for energy to repair and replenish after work. Chromium is involved in carbohydrate metabolism and other insulin dependent processes such as protein and lipid metabolism12. As performance horses exercise, increased levels of cortisol work against insulin as insulin attempts to move glucose and nutrients into muscle cells. Chromium supports more efficient insulin function by stabilizing insulin receptors leading to more efficient movement of glucose from the blood stream, thus reducing the negative impacts of exercise stress and increasing the body’s physiologic ability to move nutrients into muscle cells to function efficiently during exercise and rebuild muscle broken down following exercise13. Research in Thoroughbreds during exercise has demonstrated blood glucose was controlled on lower insulin levels versus control, which demonstrated higher insulin sensitivity when they were supplemented with chromium11. 

Another potential benefit to the improved insulin sensitivity demonstrated in performance horses supplemented with chromium propionate is in supporting the signaling pathway for protein synthesis, which is the re-building of structures. When insulin sensitivity is improved, glucose can more readily be available for protein synthesis. Insulin infusion in mature horses was shown to stimulate whole-body protein synthesis and activate the upstream and downstream effectors of mTor signaling in the gluteus medius muscle1. Simply put, this means is there was an increase in protein synthesis, or a re-building of muscle.

Glucose – An Important Component for the Working Horse

Glucose is the key energy source for every cell in the horse’s body and BCAAs stimulate protein synthesis. The proprietary BCAAs and chromium in Rebound Technology™ have been shown to make this key energy source more readily available to the cells of the horse. Rebound Technology™ can be extremely important for the performance horse needing muscle repair and remodeling to rebound in between shows and workouts.

Nutrena Nutrition Tips: Feeding Horses During Reduced Work

Learn our top tips for feeding your horse during reduced work. Tiffany Pattison, a consultant for Nutrena, shares valuable insights and recommendations for modifying your horse’s nutrition plan to maintain optimal health and performance during periods of reduced activity.

Understanding Workload Changes

There are various situations that can lead to changes in your horse’s workload. If you show seasonally, your horse might experience periods of intense work during competition time and more relaxed schedules during the off-season. Trail riders, however, tend to ride harder in the spring, summer, and fall months, but take a break when the winter weather turns unfavorable. And of course, there is the unfortunate scenario of injury resulting in stall rest or limited turnout. By recognizing these factors, we can better prepare ourselves for adjusting our horses’ diets accordingly.

Selecting the Right Feed

When it comes to feeding, hay is the cornerstone of your horse’s nutrition. Always remember its significance and consult with a nutritionist for guidance if you have concerns. There are several different feed options available for your horse when their workload is reduced. There are high-fat pellets, textured feeds, and standard pellets, each with its own unique characteristics. It’s crucial to choose the feed type that aligns with your horse’s preferences and specific needs.

Weighing Your Horse’s Feed Accurately

Accurate measurement of feed is key to providing the right amount of nutrition to your horse. We all have our own ways of measuring, whether it’s a scoop, cup, or coffee can. However, it’s essential to establish precise measurements to ensure consistency. That’s where tools like a scoop scale or even a shipping scale can come in handy. Alternatively, you can weigh your horse’s feed in a ziplock bag to determine the exact amount. Remember, precise measurements lead to precise nutrition!

Adapting the Diet for Horses with Reduced Workload

It is a common misconception that you should significantly reduce feedings when your horse experiences stall rest or reduced work. That’s just not the way to go! Instead, adjust the feed quantities based on your horse’s activity level. Refer to the feeding instructions on the feed tags, which usually indicate recommended amounts for maintenance or light work. By following these guidelines, you’ll ensure your horse receives the necessary nutrition without unnecessary weight gain.

Exploring the Role of Diet Balancers

Enter diet balancers, the superheroes of horse nutrition during periods of reduced workload. These highly concentrated and balanced feed options, such as Nutrena’s Empower Topline Balance, provide all the essential nutrients your horse needs without adding excessive calories. Diet balancers are especially beneficial for horses on stall rest or light work, helping maintain their hair coat, hoof condition, and muscle strength. By incorporating a diet balancer into your horse’s feeding routine, you’ll keep them in tip-top shape, even when exercise is limited.

By understanding your horse’s changing workload, selecting the right feed, measuring accurately, and incorporating diet balancers when necessary, you can ensure your equine companion receives the optimal nutrition throughout every stage. Remember, a well-fed horse is a happy and healthy horse.

Ask the Expert: How Many Horses Can Your Pasture Support?

Horse grazing representing How Many Horses Can Your Pasture Support?

We are often asked “how many acres of pasture do I need for my horses?”. In today’s blog we are using one owner’s experience to review how to determine the carrying capacity of your horse pasture to ensure optimal grazing conditions.

Expanding Your Herd

We’ve finally purchased a horse property! It’s 7 acres with about 5 acres in pasture. We have 2 horses, but are looking to expand our herd. However, we do not want more horses than what our pasture can hold since we do not want to feed hay (or much hay) during the summer. How many horses can our pasture support? 

How Much Pasture Do Your Horses Need?

In general, 2 acres per one 1,000-pound horse is recommended if owners expect the pastures to provide most of the horse’s nutrition during the growing season. However, this is highly variable and depends on several factors including geographical location, soil type, rainfall, and management. Although location, soil type, and rainfall are mostly out of an owners control, management can be controlled and includes mowing, fertilizing, controlling weeds, resting (e.g. avoiding over-grazing), and dragging; all recommended best practices for horse pasture management.

Your 5 acres of pasture should be able to feed 2.5 1,000-pound horses during the summer grazing season. If your farm is on sandy soil, there is a drought, or you choose not to do any pasture management (e.g. mowing, fertilizing, weed control, resting, and dragging), then 5 acres might not be enough for your two horses and hay supplementation would be needed. On the other hand, if your farm has heavier soil, there is good rainfall, and you practice good pasture management, then your pasture should be able to support your two horses, and maybe one more, during the summer grazing season. 

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.

When to Start Spring Grazing

It is tempting to turn horses out into spring pastures at the first sight of green grass, especially after a long winter. However, spring grazing should be introduced slowly and delayed until grasses reach 6 to 8″ to optimize both the health of the horse and pasture. When horse pastures reach 6 to 8″, begin grazing for 15 minutes, increasing the grazing time each day by 15 minutes until 5 hours of consecutive grazing is reached. After that, unrestricted grazing can occur.

Why is this recommendation so important? Even though hay and pasture are both forms of forages, there are significant differences. Dried hay is approximately 15% moisture compared to fresh pasture that is 85% moisture. The horse is a hind-gut, fermenting herbivore that relies extensively on the microbes present in its gastrointestinal tract to be able to process forages. The microbes are a mix of different organisms that work together to the benefit of the horse. If the feedstuffs the microbes are utilizing change suddenly, there may be too little time for the microbial populations to adjust to the change. Instead, large numbers of them die, while others flourish, setting up a situation where toxins may be absorbed by the horse, resulting in digestive dysfunction and possibly colic. A gradual change from one feedstuff to another provides enough time for the microbial populations to adjust.

Additionally, pasture grasses need sufficient growth before grazing is allowed. Photosynthesis (the process of converting solar energy to chemical energy) occurs mainly within the leaves of plants. If the leaves are grazed too early (prior to 6″ tall) or too often, plants can lose vigor, competitiveness, and root structure due to the lack of photosynthetic ability. This will lead to eventual die back and overgrazed areas being replaced by undesirable plant species or weeds. Grazing should cease when forages have been grazed down to 3 to 4 inches. At this time, move horses to another paddock or a dry lot. Grazing can resume when grasses regrow to 6 to 8″. On average, about 2 acres of well-managed pasture can provide the forage needs for one horse during the grazing season.

It is critical to slowly introduce horses to spring pastures. So, the following is worth repeating, when horse pastures reach 6 to 8″, begin grazing for 15 minutes, increasing the grazing time by 15 minutes each day until 5 hours of consecutive grazing is reached. Following this recommendation will help ensure both horse and pasture health.

Hydration In Horses: Drink Up! Keeping Your Horse Well Hydrated

brown horse drinking representing Hydration In HorsesMany regions of the country have been experiencing high heat and humidity this summer, so naturally, the concern of proper hydration comes to mind.

Reduced water consumption in horses may impair performance and increase the risk of impaction colic.

Additionally, horses may sweat more profusely, resulting in faster dehydration. So what’s a horse owner to do?

How Much Water Should Your Horse Consume?

The first key element is to make certain that horses have ready access to clean, palatable, cool water at all times or at very frequent intervals. Horses will normally consume about 1 gallon of water per 100 lbs body weight, so an 1100 lb horse will require a minimum of 11 gallons of water per day. This quantity can increase substantially during periods of exercise, high heat/humidity or for lactating mares.

Tips to Ensure Ample Water Intake To Maintain Hydration In Horses:

  • Horses do not like to consume warm water in warm temperatures. Automatic waterers or large tanks, located in the shade and cleaned regularly, may be good options. If you supply water in buckets, you should clean them regularly and refill them regularly.
  • If you are traveling to a show or other competition, it is essential to monitor water consumption, particularly if temperature conditions change.
  • It is routine in many barns to flavor the water with something like wintergreen or peppermint at home so that you can flavor the water in new facilities to match the home water.  Read here for tips on training your horse to drink water away from home.
  • Do NOT use soft drinks or any material containing caffeine as these can trigger positive drug tests.
  • Taking horses to facilities with chlorinated water can sometimes reduce water consumption without proper precautions.

Salt Consumption in Horses: Key Considerations

Ensuring salt is offered free choice is also key. Things to keep in mind for salt consumption in horses include:

  • Horses require 1-2 ounces of salt per day, and this can increase to 6 ounces per day with exercise in hot weather conditions.
  • Horses often consume loose salt more readily than salt blocks.
  • When evaluating the total diet for salt consumption, commercial feeds normally contain 0.5-1.0% salt. It is not typically any higher than this, due to problems with palatability.
  • If a horse is bored or has been salt deficient, it may over-consume salt while in a stall.
  • Horses may have additional electrolytes, whether commercial or personal recipe, as per directions before, during, and following completion, but take care to ensure that the horses are drinking adequate water. Administering electrolytes to a horse that is not drinking properly, or allowing a horse to over consume salt without adequate water, can lead to electrolyte imbalances. Offer plain water along with electrolyte-added water.

Electrolytes and Hydration In Horses: Ensuring Balance in Summer and Competition

Horses need to be offered water throughout the day at a competition, and should be re-hydrated following exertion. They cannot cool out and recover properly without being re-hydrated. Keeping horses properly hydrated and maintaining electrolyte balance is extremely important in order to make a safe transition from cool temperatures to summer time and competition.

Amino Acid Requirements for Horses

In order to fuel, repair, and recover muscle, equine diets must optimally contain Horse feed being put in a bucket Amino Acid Requirements for Horsesa superior amino acid profile, including all 10 of the essential amino acids.

Most horse owners can quickly name the crude protein level in the feed they provide their horses. But, what horse owners really need to know about is the amino acid content.

Essential and Nonessential Amino Acids

Amino acids constitute protein, much like how links form a chain. There are two basic categories of amino acids: Essential and nonessential.

The horse cannot produce essential amino acids in its digestive tract, so it needs to obtain them through the diet. Nonessential amino acids, however, can be synthesized internally.

Understanding Limiting Amino Acids:

Some amino acids are known as “limiting” amino acids. If a horse lacks this amino acid type, it cannot utilize the remaining amino acids in the feed.

If the horse has enough of the first most-limiting amino acid, but then runs out of the second most-limiting amino acid, it can’t use the remaining amount of the third most limiting, and so on.

In horses, the first three most-limiting amino acids, in order, are lysine, methionine and threonine. In general, if these three amino acids are adequately present, the ingredients used also supply the remaining amino acids sufficiently.

Guaranteed Amino Acid Analysis and Balanced Feeds

It is increasingly common to see these three amino acids listed on the guaranteed analysis of horse feed tags, as it is an indication of the quality of the protein sources and the balanced nature of the feed.

If you are looking for a feed that may help impact topline, be sure to look at the guaranteed analysis on the feed tag. Specific Nutrena feeds such as SafeChoice products, ProForce products, and Empower Topline Balance guarantee and specify amino acid levels on the tag.

The amino acids included in Nutrena’s Topline Balance products are included in specific amounts and ratios. Research has shown that this specific combination and type of amino acids help to support a healthy topline.

Guaranteed amino acids on the tag is a good starting point. Let the horse tell you if the feed is working by regularly evaluating and noting changes in topline condition.

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.
