Overweight Horses: Winter Management

Feeding the overweight horse can be tough, but winter poses an even greater challenge with managing a delicate balance between providing enough energy to stay warm, yet not so much he is unable to shed those unwanted pounds.

When considering the feeding program for your overweight horse, first take into consideration the forage type, quantity and frequency he is being fed. The overweight horse benefits most from grass hay over legume hay due to it’s reduced calorie content. Most overweight horses do best on grass hay with a ration balancer to provide balanced levels of necessary vitamins, minerals and amino acids.

Consider how frequently he has access to his forage. Is he limit fed or allowed free access anytime of the day or night? Generally speaking, limit feeding the overweight horse is one half of a critical equation to helping him shed those pounds. Forage should make up the bulk of any horse’s ration and the overweight horse is no exception. His forage ration should be between 1.0-1.75 lb. hay per 100 lb. body weight, per day. For a 1,000 lb. horse, this would range from 10-17.5 lb. of hay each day.

Next, consider his living arrangement: Is he kept by himself or does he share feed with herd-members? If possible, put him in isolation from other members of the herd to help control his intake. Overweight horses may be considered ‘survivors’ in the wild as they oftentimes bully their way into their herd-member’s food supply, but as domesticated animals, they need not exhibit this behavior when a consistent, good quality supply of food is provided. Isolating him from those he can bully will keep his portion size to what you fed him.

Next, take into consideration how he is managed: Is he kept in a stall, coat clipped in a heated barn? Is he turned out on a regular basis? Does he live outside with access to a run-in or loafing shed? How he is managed can play into how to help him lose weight, yet stay warm during the oftentimes brutal winter months. Horses that are most frequently stalled benefit from turnout, safe footing permitted. Those turned out full-time should be monitored for the need of a blanket should weather conditions deteriorate enough to warrant; moisture penetrating the thick winter coat as well as a biting winter wind can cut through the toughest of their protections.

Finally, consider his activity level. Winter in most parts of the United States bring snow, ice and/or frozen footing which can pose a challenge for horse owners. Good footing is essential for reducing the occurrence of injury during exercise and this is no less important than in the winter months. Here are a few suggestions for exercising your overweight horse when the footing is less than ideal.

Hand walking – up or down the driveway, on a trail or around an arena is good for him and a great time to bond.
Pasture turnout – solid footing permitting, turn him out for time to romp in the snow and work off some energy.
Time on the lunge line – provides better control over his activity level than turnout and he can work faster than a hand walk.
Trailer to a near-by indoor arena (if there is one close by) for lunge-work, saddle time or just some quiet hand walking.

Helping your overweight horse lose during the winter can be a delicate balance, but with some effort and creativity he can start out the New Year on the way to being a trimmer, healthier horse.

What is “Normal” for my horse?

We’ve all heard the warnings for proper horse care: monitor your horse frequently, and if something is not normal, call your veterinarian. But what is “normal” for your horse? While it is a good idea to pay attention to your horses’ vitals when you do not suspect that anything is wrong in order to establish a baseline, there will be times when that is not feasible. What if you have a new horse on your place that you fear is not feeling quite right? Or perhaps you are taking care of a friend’s horse and are not familiar with how this horse normally functions?

The following is what is considered “normal” for most horses – following this chart when you suspect a problem will help pinpoint what is wrong and allow you to give a more accurate report to your vet.

Temperature: Adults – 99.5°F – 100.5°F; Foals 100.5°F – 101.5°F
1. To take your horse’s temperature: Use a large animal thermometer or a human rectal thermometer held in the rectum for 2 minutes. *Note – temperature will be elevated after exercise.
Heart Rate: Adults – 24-36 beats per minute; Foals – 40-60 beats per minute.
1. To take a heart rate: Using a stethoscope, listen at the wall of the chest, just below the elbow.
Respiratory Rate: Adults – 12-24 breaths per minute; Foals – 32-54 breaths per minute.
1. Note: respiratory rate may be influenced by stress, excitement, or exercise.
Mucous Membranes: Mucous membranes should be pink and moist, with a capillary refill rate of 1-2 seconds.
1. To test the capillary refill time: Part the horse’s lips to expose the gums. If you press gently and briefly on the upper jaw with your thumb you will see the blood is forced from the gum. Count how long it takes for the gum to return to its normal color.
2. Always check mucous membranes in normal light or with a flashlight. Do not use fluorescent lighting, which can cause membranes to look unusually pale. Abnormal membranes are pale/white, blue, dark red, or purple in color.

Physical Exam:

Look for differences in the left vs. right sides of the body.
Check for discharge from the eyes, nostrils, mouth, rectum, vulva, sheath, wounds, abscesses, or any other evidence of trauma.
Note if the horse has passed manure or if there is diarrhea on its tail.
Listen on both sides of the flanks for normal gastrointestinal activity.
Check to see if the abdomen is distended.
Check to see if the horse is working hard just to breathe

Attitude:

Is the horse alert and interested, dull or depressed, or acting differently than normal?
Can the horse walk and move normally at the walk and trot?
Is the horse bearing weight equally on all four limbs?
Has the horse eaten or drunk and is there evidence of fresh manure?
Note if the fencing/stall shows signs of a struggle.
Be sure to check other horses at your facility for similar signs/symptoms.

Feeding Salt to Horses

We normally think of salt more as a warm weather requirement. Horses do require about 1-2 ounces of salt per day to provide help meet their requirement for sodium and chloride. This requirement can increase to 4-6 ounces of salt per day in hot climates or under exercise where losses in sweat increase greatly. Inadequate salt in the diet can result in abnormal eating behavior such as licking or chewing objects which have salt on them (fork handles etc.) or licking/eating dirt. Water intake may also decrease, increasing the risk of impaction colic. In more extreme cases, horses will stop eating and may experience muscle incoordination.

Cold weather salt intake is sometimes overlooked. Horses do not lick salt blocks as readily as some other specie even when the salt block is a comfortable temperature. During cold weather, outdoor salt blocks become even less inviting! Would you lick something that is freezing cold?

A good option to maintain year around salt intake is to offer loose salt available free choice, either in stalls or in a covered mineral feeder. Salt intake from loose salt has been observed to be higher than from salt blocks due to the ease of consumption. When purchasing loose salt, ensure that you are selecting salt that is intended for animal consumption (NaCl, iodized table salt, plain white salt), and not a mineral salt blend (red salt), or salt that is intended for de-icing.

If horses are salt starved, it may be a good idea to limit the amount of salt put out for them until they have adjusted their intake. It is essential that fresh clean water at an appropriate temperature be available at all times as well.

Commercial feeds normally contain 0.5-1.0% salt, so horses on this type of feed will typically consume less free choice salt than horses not receiving salt in their feed. They may still benefit from having loose salt available free choice. A salt block is better than not having any salt available free choice, but may not be as effective in maintaining salt intake in cold weather or when high intakes are required in hot weather.

Providing salt free choice is a good management tool that can help your horse eat and drink well all year long!

Feeding Electrolytes to Horses

As a follow-up to our recent post on providing adequate water for horses, the following information should be helpful in understanding the use of supplemental electrolytes for horses. There are a wide range of practices and opinions within this topic, so here are some basic guidelines to keep in mind:

Provide loose salt free choice at all times to all horses. If loose salt is provided, horses will usually consume the right amount to meet their electrolyte requirements without having to use an additional supplement.
Horses administered any form of electrolytes need to be consuming adequate water.
Electrolytes should never be force fed to a dehydrated horse, and any horses supplemented with electrolytes should be monitored for dehydration (skin pinch test, mucous membrane color and hydration, capillary refill).
Electrolytes can be used to encourage drinking (e.g. during transport or if horse doesn’t like to drink away from home). Usually thirst/drinking is stimulated within 3-4 hours after dosing.
In cases where horses are working extremely hard and losing electrolytes through substantial sweating, a supplemental electrolyte in addition to the salt may be beneficial.
1. If heavy sweating due to competition is anticipated, administer electrolytes 1-2 days prior to competition, during the competition and 1-2 days after a competition.
2. Doses are usually within the 1 – 4 oz range, depending on sweat loss and the heat and humidity levels.
3. A general rule of thumb is usually 30 – 90 g per hour of strenuous work, or follow manufacturer’s instructions if using a commercial product.
An oral dose (paste/syringe) is recommended over top dress or adding to water, as these methods can create palatability issues and can result in feed/water refusal.
Many commercial products have more sugar that electrolytes in them, so buying a commercial product where sugar is not listed as one of the main ingredients is very important. Potassium, sodium, chloride, and calcium are the most important electrolytes.

Water-The Most Important Nutrient for Horses

Water is the most important nutrient that we provide for horses on a year around basis.

Understanding Horses’ Water Needs

Horses need 2 to 3 times more water than other feedstuffs. An 1100 lb horse on a dry forage diet at an average temperature of 68 degrees Fahrenheit will need a minimum of 6-7 gallons of water per day or 48-56 lbs of water, and many horses will drink more water than the minimum. We all appreciate that the water requirement may double at high temperatures, but may not realize that at -4 degrees Fahrenheit; the quantity required is about 10-12 gallons per day, or actually higher than at moderate temperature. The onset of cold weather can actually increase the requirement for water because there is no fresh grass and the air is very dry.

Debunking the Snow Eating Myth

There is a misconception that domestic horses can easily eat enough snow to survive. While horses in the wild do adapt to lower water intakes, partially because food intake is also frequently reduced, horses can survive longer without food than they can without water. Reduced water intake can also impair digestion and potentially contribute to the incidence of impaction colic.

It also requires a great deal of energy to eat snow, melt the snow in the body and raise the fluid temperature to normal body temperature of 99.5- 100.5. Increasing the temperature of 10 gallons of water from 32 degrees to 100 degrees takes about 1372 Calories or about the amount of digestible energy in a pound of feed. Melting the snow to get to water will take a great deal more energy and the horses will not readily eat a pile of snow the size of 20 five gallon buckets. It takes about 10 inches of snow to have one inch of water.

The Benefits of Providing Fresh, Clean Water

Reducing the Risk of Colic: Ample hydration helps minimize the occurrence of colic, a common digestive disorder in horses. Insufficient water intake can impair digestion and increase the likelihood of impaction colic.
Maintaining Healthy Digestion: Water plays a crucial role in the digestive process, aiding in the breakdown and absorption of nutrients. Proper hydration supports optimal digestive function and nutrient utilization.
Maintaining Body Condition: Hydration is essential for maintaining overall health and body condition in horses. A well-hydrated horse is more likely to maintain a healthy weight and exhibit good coat quality.
Cost Savings on Feed: Ensuring horses have access to sufficient water can actually save money on feed costs. Proper hydration supports efficient nutrient absorption, reducing the need for excessive feed intake.

By prioritizing year-round hydration, horse owners can effectively support their horses’ overall health and performance.

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.

Feeding Horses in the Winter

As I was reviewing the feed program for one of my client’s lesson horses, she mentioned ordering corn to add to the feed for the winter. She felt this would provide the horses extra warmth in the cold weather. This is a common winter practice with many farms, and I explained to my client that she was correct to increase the horse’s caloric intake with falling temperatures. There is a much better alternative to corn, though – it is much more efficient and effective to increase the forage portion of the diet to help create internal heat in the winter. This is due to the fermentation process the forage goes through in the hindgut, and the heat that process gives off.

The term “critical temperature” is used determine at what temperature a horses nutritional requirements change to maintain normal body temperature. I use the temperature of 40 F as a benchmark for calculating winter diets. In essence for every 1 degree below critical temperature, I increase the horse’s caloric intake by 1%. So, if my 1000 pound horse were receiving 18.6 Mcal (18,600 calories per day), I would increase his diet by 1860 calories when the temperature goes to 30 degrees (10 X 186). If my hay has tested at 1 Mcal (1000 calories) per pound, an additional 2 pounds of hay will help my horse maintain his body condition at that temperature.

I also encourage my clients to feed a well fortified concentrate during the winter months. The lack of fresh pasture, limited sunlight hours, and often diminished hay quality require better fortification. Make sure your horse feed provides adequate levels of vitamin A, D and E. Feeds offering probiotics and prebiotics, as well as biotin are also encouraged. If you are feed a grass hay or alfalfa hay, make sure your calcium and phosphorus levels are also balanced accordingly in your feed.

Water consumption is imperative during winter months. Make sure that the buckets are free from ice and frozen debris. In the winter horses will consume 10 to 12 gallons of water per day. Ideally the water temperature should be at 50-65 F to encourage drinking.

Examine your horses body condition score monthly during the winter to maintain a healthy horse!

Hoof Health and Your Farrier

If your horse has ever had issues with his or her feet, the old adage, ‘no hoof, no horse’ could not ring truer. When considering hoof health, multiple factors influence the state of your horse’s feet including nutrition, conformation, environment, use and overall management and care.

One of the keys to success of healthy feet is your farrier. He or she plays a critical role in the maintenance and ongoing assessment, treatment and wellness of your horse. When selecting a farrier to work with you and your horse, there is more than just price to consider. Here are some questions to ask to learn more:

What schooling or certification have they received?
If new to the industry, have they completed an apprenticeship? Is the Master known for doing good work? Ask around your barn, veterinarian, tack or feed store to learn more.
Have they worked with a veterinarian? Are they willing to work with a veterinarian?
Are they a member of a professional organization such as the American Farrier’s Association or the American Association of Professional Farriers?
What do their current or former clients have to say about them? Check references.

Rasping hind foot — Deb, my farrier, rasps Ferris’s left hind foot after a trim.

Consult with your farrier on the appropriate frequency for trimming. For example, I live in a Northern climate, where hoof growth is slower in winter months and faster in summer months. My farrier trims my horses every 4-5 weeks in the summer and 6-8 weeks in the winter.

The genetics of your horse have a significant impact on the management program. Some horses are blessed with good heels, strong walls and naturally cupping soles. Others may have issues with low slung heels, flares or misshapen soles. Such feet may require more frequent or special trimming methods and in some cases, shoes may be required to maintain soundess. Refer to your farrier and vetrinarian to determine if this solution is best for your horse.

Be sure you are regularly picking out your horse’s feet with a hoof pick between farrier visits. One of the best times to do this is grooming before and after work. Check for rocks, bruises and signs of concern, such as white line disease or thrush. The frequent time spent observing can help you understand the overall health of his feet. In partnership with your farrier, your efforts toward regular care of his feet will go a long way toward soundess for years to come.
