## Horse Feed: More Than Just Percentages

Horse owners frequently compare feeds based primarily on the information on the feed tag or supporting data from web sites.  While this is a quick comparison to make, it may not always be the best comparison.  Why, you ask? Well, what is most important to the horse is the total amount they actually consume.  To get this number, the percentage in the feed must be multiplied by the amount fed, making sure to account for different unit of measurements, such as supplements that are fed in ounces instead of pounds.

One example where this is important is with the protein percentage.  As ration balancer horse feed products are becoming more and more popular, some folks see that they typically have 30% protein or more, and worry that the level is way too high for a horse.  But with a ration balancer, a 1000 lb horse only gets 1-2 pounds of the product a day, compared to 4-6 lbs of a more traditional 12% feed.  So, if we do the math, here’s what we see:

• 30% protein X 2 lbs of feed = 0.6 lbs of protein a day from a ration balancer
• 12% protein X 5 lbs of feed = 0.6 lbs of protein in a day from a traditional feed

Another example where this calculation is useful is in the variety of fat supplements available on the market today.

• A powdered fat supplement has 99% fat, being fed at a rate of 2 oz a day, adds 0.124 lbs of fat to the daily diet.
• A stabilized rice bran supplement that has 22% fat, fed at a rate of 2 lbs per day, adds 0.44 lbs of fat to the daily diet.

And of course, on top of this, we must ALWAYS remember to factor in the hay – not just the grain.  A horse will consume much more hay per day than grain, so the difference in a few percentage points is magnified when looking at the hay portion of the diet.  It may take a little math, but looking beyond the percentage of a particular nutrient is something your horse would thank you for if he could speak!

## Using Hay Replacers for Horses

When times of severe draught or other weather phenomenon result in poor quality or availability of pastures and hay, horse owners often turn to complete feeds (i.e. feeds that contain a full diet of roughage, protein, vitamins, minerals, and other needed nutrients) or hay stretchers/replacers (designed to replace the fiber component of the hay/pasture that is no longer available).   These products can be extremely useful to horse owners to help them through the tough hay times, but they do come with some usage guidelines to keep horses happy and healthy.

• Follow the recommended feeding rate.
• This is of particular concern if the product is being used as the sole diet.  To keep gut health intact, enough fiber must be consumed each day for regular gut function.  And, to keep the horse healthy overall, it is critical to ensure they are receiving all the balanced nutrients that they would normally get through a combination of hay, pasture, and added concentrate feed.
• Horses tend to crave long stem fiber to chew on, which is missing in the diet made up of complete feed or hay stretchers.
• Owners will most likely see unwanted behaviors begin, such as wood chewing, cribbing, or weaving, without some grass or hay to keep their horse’s mouth and mind busy.  While the full daily allotment of hay may not be available or affordable, it is a good idea to offer at least a flake or two each day to help prevent these behaviors (and save your fences).  Hay cubes are an option if pasture or traditional baled hay is unavailable.
• Ensure proper water and salt consumption.  Proper hydration levels are essential to keeping the gut moving properly.

In the absence of available forage, providing a complete feed concentrate is a better option than feeding a concentrate that is designed to be fed with forage, by itself.  With proper management and attention to detail, both the horse and the owner’s pocketbook can pull through the hay shortage!

## Selecting the Right Feed

Browsing through the aisles of your local feed store, it’s likely you have noticed the variety of horse feeds available.  National brands, regional brands and local manufacturers all crowd the shelves, adding to the confusion.  Which feed is right for your horse?  Here is a quick guide of what to consider when you are contemplating your feed selection.  Start by assessing your:

1. Horse’s life stage
2. Horse’s activity level
3. Any health issues your horse may have
4. Feed budget

Most feeds are designed to meet the specific nutrient requirements of life stages and activity levels of horses, and generally will specify on the packaging what they are designed for.  When estimating your horse’s activity level, be reasonable in your classification since over feeding energy can make him ‘hot’ and he may gain unwanted weight.  Generally when people see this happening, they tend to reduce the amount fed below the recommended feeding rate instead of changing to a lower energy feed.  This is not advised, as dropping below the recommended feeding rate means your horse is not getting the essential micro-nutrients he needs.  Try switching to a lower energy feed such as a maintenance feed or balancer.  Most maintenance feeds are formulated to provide mid to low energy levels.

If your horse has a specific health issue that can be influenced by his feed, make sure to seek out the information from the bag, your veterinarian or directly from the manufactor.  For example, horses with a history of feed-related laminitis are often best suited to a diet feed or ration balancer which provide much needed minerals and vitamins while keeping starch levels under control.

Finally, consider your budget.  The features and benefits of feed typically drive up the cost; so ask yourself, can I afford to feed this product at the recommended feeding levels?   Note that feeding rates vary between products and this can influence the cost to feed your horse per head, per day; it is not enough to consider the price per bag alone.  If you are feeding an inexpensive feed but loading it with supplements, it may cost you more than purchasing a commercial complete feed and cutting out the supplements.

Complete feeds are formulated with all the necessary nutrients to meet your horse’s needs in the proper ratios.  When feeding a complete feed, be sure to follow feeding directions closely and monitor his weight through assessing his body condition score and calculating his weight periodically.

This is a very quick guide to help you navigate the increasingly complex decision of how to select the feed that is right for your horse. For more in-depth information, refer to a feed selector or ask a qualified equine nutritionist.

## Stretching Your Horse Hay Budget

We all know that next to water, forage is the most important part of a horse’s diet. Without it they just can’t survive.

With the high prices of forage there are a few ways you can get a little more out of the forage you feed.

1. Start by selecting the best quality hay your budget will allow – higher quality means more nutrition in every bite.
2. If practical, weigh out the appropriate amount of hay your horse should eat at each feeding so that the excess isn’t wasted. On average, a horse should eat between 1.5-2% of his body weight in forage per day.
3. You may also choose a feed that contains yeast cultures (prebiotics) and direct fed microbials (probiotics) like Lactobacillus Acidophilus. These elements will help your horse’s hind gut better digest and utilize the forage it takes in.
4. If your horse is on pasture, a good practice may be to divide your pasture into sections and rotate sections on a frequent basis to allow for maximization of forage produced.
5. If hay or pasture is in truly short supply, try utilizing a hay extender product.  While it is always beneficial to keep at least some long-stemmed roughage in the diet, using a hay extender can make the few bales of hay you have last quite a bit longer.

## Judging Hay Quality for Horses

Because hay is such a common part of a horses diet, judging quality on visual inspection is important, as lab analysis is not always easily available.  Here are three simple things to look for to help you select the best hay for your horses and your money.

1. The initial check that most people are familiar with is color and smell.  Horse hay should be bright green and smell slightly sweet.  Brown hay indicates either a problem in the baling process, such as being rained on, or age.  Acrid or musty smells generally indicate the presence of mold.
2. Another sign of good horse hay is the leaf:stem ratio.  The more leaves, the better, since the leaves are where most of the nutrition in the hay is stored.  Hay that has too many hard, woody stems is difficult to digest.  Even if it cheaper, most horses will pick through and leave the bulk of the stems behind, costing more in the long run.  High quality hay is fine-stemmed, pliable, and full of leaves.
3. Type of hay is another factor.  Grass hays, such as timothy or orchard grass, generally provide sound basic nutrition.  The higher the concentration of legumes, such as alfalfa or clover, the higher the energy content.  High quality alfalfa is generally better than high quality grass hay, but good quality grass hay can be better than average quality alfalfa hay.

The best thing, in the end, is to have hay tested.  This is not always feasible for every load, but if your hay source is consistent from load to load, this may be a good option to get a general feel for what nutrients your hay contains.

## Reading Horse Feed Directions – How Much to Feed?

When horse feeds are formulated, they are developed to provide nutrition to all sizes of horses – nutrient needs go up as the size of the horse goes up.  So, feeding directions are often provided in the following format:

• Activity Level                   Lbs of feed per 100 lbs of bodyweight
• Maintenance                     0.3-0.5
• Light Exercise                   0.4-0.6

So, how do you figure out how much to feed your horse? Start with knowing the weight of your horse.  Then, divide that weight by 100, and then multiply the result by both of the amounts of feed given in the directions above.  The resulting two numbers will tell you the range of how much to feed your horse to give them the nutrition they need for both their size and their activity level.

Example Feeding Directions:

1200 lb horse, in light exercise.

1. (1200 ÷ 100) = 12
2. (12 × 0.4) = 4.8
3. (12 × 0.6) = 7.2

In this example, this horse would need to eat between 4.8 and 7.2 lbs per day of this feed to receive the nutrition he needs.  Some horses that are easier keepers can fall to the lower end of the range, while harder keepers may need to push the upper limit.

If you do this math for your horse, and find that you are feeding outside of the designated range, you should search for a feed that is more suitable to your horses needs.  Hard keepers, for example, may require a feed that is higher in calories per pound, while easier keepers might require a feed with fewer calories and more concentrated levels of vitamins and mineralsSuch a feed might cost more per bag, however the ability to pack more punch in a smaller feeding might actually result in a cost saving!

## Making Cents Out of Horse Feed Costs

I was recently called to a boarding and lesson barn to help the owner evaluate her feed program.  With the rising costs of bedding, labor, insurance, electricity and hay, she wanted to look at options at saving money.

The farm housed about 40 Thoroughbreds.   Twelve of the horses were active in a lesson program, and the other horses activity levels ranged from pleasure maintanece to moderate work/show.   The Body Condition Scores of the horses ranged from 4 to 6, and the owner explained that some of the horses were harder keepers than others, with daily grain intake ranging from 1 to 18 pounds of grain per day per horse.

We examined the hay and found it to be a good quality timothy grass mix.  The horses were getting about 1.5% of their body weight per day in hay. For grain, she was using an economy feed that was priced at \$8.99 per bag.  She felt that with the large number of horses on the farm and rising cost she could not afford the premium feeds that were almost \$14 per bag.

When we examined the feed tag from the manufacturer, the suggested feed rate was 1 pound per hundred pounds of body weight (that’s 10 lbs of feed for a 1000 lb horse!), and the fortification of the product was minimal.  The owner then explained that she and the boarders did purchase supplements to provide added biotin, yeast culture, copper, zinc and selenium.  Some of the hard keepers were also given a fat supplement.

To determine how much she was spending on feed, we did the following math:

• Current Feeding Program = 10 lbs feed + supplements
• ~ \$8.99 per bag / 50 lbs per bag = \$0.18 per pound
• ~ \$0.18 per pound X average 10 lb per day feeding = \$1.80 per day per horse
• ~ Plus the various costs of nutritional supplements to make up for the lack in feed
•
• Proposed Feeding Program = 5 lbs feed + no supplements
• ~ \$14.00 per bag / 50 lbs per bag = \$0.28 per pound
• ~ \$0.28 per pound X average 5 lb per day feeding = \$1.40 per day per horse
• ~ No need for nutritional supplements!

When we calculated the cost per horse per day based on feed consumption and supplements, some of the horses exceeded \$3 per day!  When we compared that to the feed rates on the premium line feeds, not to mention complete fortification levels and the time savings in not having to sort out servings of supplements every day, the premium feed was a better value in the long run.
