Integrity Lite and Integrity Lite – No Molasses are very low starch formulas and do not contain grans. In fact, none of the Integrity products contain corn or barley.

You need to first take a look at what is being fed compared to how the horse is used. This page on How to Determine What to Feed Your Horse offers a series of questions that helps me have the necessary understanding of your horse to suggest an appropriate balanced diet.
Early commercial formulas were grain-based with corn, barley, and oats as three of the first four ingredients. Those early formulas did not have added fat and only contained about 2.5% fat. Today, rice bran and oil are added to formulas and fat content will vary from 4-12 %. As a young horseman I never cared for those heavy grain-based feeds which influenced how I developed balanced formulas for Integrity Horse Feeds. Integrity Lite contains 4.5% fat with the fat sources from rice bran and oil.

There is a lot of confusion in the industry on "hot feeds" or what causes a "hot horse.” Experience has showed me time and time again that there are other reasonable explanations for this behavior. While I am also not a fan of heavy grain-based feeds, it may not be the cure you are seeking for your horse being at the higher spectrum of energy or having excitable reactions to their surroundings


I would need to know a lot more about your horse: body weight, Body Condition Score, age, frequency of work (days & time/day), work intensity, hay & amount fed, other feeds fed, etc.

The “hotness” is more likely associated with breeding (genetics) or other management factors and not with diet. There is a lot of confusion in the industry on "hot feeds" or what causes a "hot horse" and usually there are plethora of other reasonable explanations for horses that are at the higher spectrum of energy or have excitable reactions to their surroundings.


Integrity Lite and Integrity Lite-No Molasses are very low starch formulas and they do not contain grains. In fact, these Integrity products do not contain corn or barley. When determining the right feed for a horse, you need to first determine the horse's use and activity level. I developed a fact sheet (in Dr. Bray's Corner) on what to feed your horse that is driven by a series of questions that help me determine an optimal, balanced diet.

Early commercial formulas were grain-based, with corn, barley and oats as three of the first four ingredients. Those early formulas had approximately 2.5% fat content and did not contain added fat. Today, rice bran and oil are added to formulas, and fat content varies from 4% to 12 %. As a young horseman, I never cared for those heavy grain-based feeds; this influenced how I developed balanced formulas for Integrity products. Integrity Lite contains 4.5% fat, with the fat sources from rice bran and oil.

There is a lot of confusion in the industry about "hot feeds," or what causes a "hot horse." Experience tells me that there are other reasonable explanations for horses that burn higher levels or energy or have excitable reactions to their surroundings. Perhaps the "hot horse" syndrome is analogous to the hyperactivity in children who eat candy, which is interesting since every child study summary I have read demonstrated that sugar/starch consumption does not make a child hyper.


How big is your scoop? His energy level might be influenced by his spirit to work and by restlessness because he's been down for a long time-it might not be influenced by the feed.

Nevertheless, with the recovery program that you noted, I would suggest the Integrity Lite. It's a balanced formula that supplies the required nutrients, produces lower energy and contains more fiber, yet contains no grains. Once you start to work him to a jog and lope with some extension, then you can make the switch back to Integrity Adult/Senior. The Integrity product line was developed using similar ingredients so that switching from one Integrity product to another can be more safely expedited, when compared to switching between feeds that have uncommon ingredients.

The amount of Integrity Lite depends on the horse's body weight and condition score, as well as the amount and type of hay it's being fed, among other factors. However, if I assume your horse is in the 1050 - 1100 lb. weight range, then I would suggest starting with about 2.5 lbs. of the Integrity Lite and adjusting the amount as you go along to maintain a body condition score of 5.5. As your work intensity increases, you will need to increase his food as well.


No. Integrity Adult/Senior and Integrity Adult/Senior - No Molasses are low-starch formulas and low-energy feed. The Integrity products do not contain corn or barley. Integrity Adult/Senior does contain a small portion of oats, which, along with modest amounts of rice bran and oil, serves as a fuel source.

The way you know that oats are a small amount in the formula is by noting that oats are the sixth ingredient on the feed label, and that beet pulp and soy hulls, the first two ingredients on the label, are the major ingredients in the Integrity Adult/Senior.

The opinion that "grains will make a horse hot" has been around a long time. As noted in a similar question, every time I have experienced a horse that was energetic, hyper, or "hot", there was a behavioral or management explanation-it was never due to the horse's feed.


The opinion that "grains will make a horse hot" has been around well before my birth. Historically, working horses were fed grains (corn, barley and/or oats) as a source of energy. As commercial formulas evolved, corn, oats, barley and soybean bean meal were the primary ingredients and were balanced with a vitamin and mineral additive. Today, most adult horses are pleasure horses. High energy feedstuffs are not needed to complement the forage portion of their diet.

I have been feeding horses for 50 years. Every time I have experienced a horse that was energetic, "hyper," or "hot", it could be explained behaviorally. It was never related to the feed. Hot-horse syndrome is often paralleled to children eating candy-and numerous studies have demonstrated that sugar and starch consumption does not make a child hyper.

By the way, Integrity Products do not contain corn or barley. The NEW Integrity Performance formula (available soon!) also does not contain corn or barley. Its major fuel sources are rice bran, oil and oats.


I assume by "could have more energy" you are suggesting he needs more energy during exercise. 3 3/4 cups of a balanced formula per day for an average sized Andalusian is not a lot for a working horse. There is more information that would be helpful in providing a feeding recommendation and I would suggest you review the fact sheet on What to Feed Your Horse.

You need to add "groceries" so there are two reasonable options for your horse to gain weight. You can increase the current amount of Integrity Lite or you can add Integrity Rice Bran. The Integrity Rice Bran is a new Integrity product that is balanced for calcium and phosphorus and has added probiotic and prebiotic for gut health and integrity. Depending on workload you may be better feeding Integrity Adult/Senior.


The Integrity Adult/Senior is lower fiber, has a bit more fat, and contains oats, thus more calories than the Integrity Lite. To provide more fuel for a horse's daily needs, you can also add fat via corn, soy or peanut oil. In general 1/2 cup is added for hair coat shine and for an energy boost, 1/2 to 1 cup per day. The horse's energy demands, work level coupled with body weight and amount of balanced formula being fed are the determining factors for the amount of oil to be added.


Your endurance journey is an impressive venture. There is of course popular press articles written about endurance riding but without reviewing the literature I do not recall any publication or popular press article that I can recommend. Obviously you will need to be sensitive to conditioning prior to the PCT ride and sensitive to changes in weight during the ride. A few considerations I would encourage:

  1. Long stem forage daily; important for gut health relative to consistency in gut motility and there is an increase in water consumption with long stem forage consumption compared to processed forage (hay pellet or cubes).
  2. Although many readers know that I am selective when recommending alfalfa hay, this level of work will require alfalfa to be part of the daily forage. Alfalfa will deliver higher levels of protein, which increases water consumption. Alfalfa also contains higher energy levels than grass forages. I suspect you should be considering alfalfa to be at least 50% of the total forage intake and perhaps even higher.
  3. Beet pulp, a soluble fiber source, has several attributes for endurance riding with which I am sure you are already familiar. Beet pulp has been documented as a good fuel source for endurance riding because of its affinity for water and it promotes gut integrity. The Integrity Adult/Senior formula's first two and major ingredients are beet pulp and soybean hull pellet. Both feedstuffs have attributes that are favorable to endurance competitive horses.
  4. In the previous bullets points emphasis has been placed on forages and the relationship of the fiber source to water. These recommendations are for promoting gut integrity but also for providing a water reservoir in the gut to support hydration during the daily work load.
  5. You will need to feed a balanced concentrate that is high in fat but not the only fat source. Based on the work load you will want the flexibility to also top dress fat (oil) to provide an addition source of energy when needed. Studies have demonstrated that dietary fat has a sparing effect on utilization of glycogen stores thus delaying the onset of fatigue via lactic acid accumulation. The Integrity Adult/Senior formula has the attributes of the balanced formula required for an endurance horse.
  6. Include an electrolyte additive during each feeding, 2 hours before the ride, every 2 hours of the work load, and 2 hours after the horse has competed the daily work. There are commercial electrolyte additives but they are expensive. You may want to make your own which is a combination of regular slay and lite salt.

Be sure you acclimatize your horse to the feeds and feeding regime. For this type of endurance endeavor feed amounts will vary, especially on the rest day. Nevertheless consistency in the feeds will be an important nutritional management consideration.


There is additional information that is needed in order to provide you more than a general response. The fact sheet What to Feed your Horse provides the series of questions for one to consider when determining what to feed. The orchard grass hay is essentially a maintenance diet. As you increase the frequency of work (riding), the intensity of work, and the length of each exercise bout, you will need to add a balanced formula that will provided an additional source of energy and nutrients. The frequency, intensity & length are factors that will determine the feed selection and amounts fed daily. However, since you are just getting started, the Integrity Adult/Senior is a balanced formula that will complement the forage portion, provide a source of energy in a balanced formula, but is still low starch because it does not contain corn or barley; Integrity Adult/Senior does contain fat (from rice bran & oil), contains soybean meal (protein source & 3rd ingredient) and does contain oats ( a higher fiber, low starch grain) but oats are not a major ingredient but enough to be one of the fuel sources for light to moderate working horses. Once I have a better understanding of your horse from the questions outlined in the Fact Sheet referenced above, I will be able to provide you some more specific guidelines.


I do not recommend feeding individual feeds such as oats, corn, etc. as an add-on or supplement to a horse's diet. A balanced formula is designed to provide nutrients and energy sources to address the established nutrient requirements of a horse relative to their lifestyle. Feeding a balanced formula that complements the forage portion of the daily diet has always been my recommendation.

There are a couple exceptions to this recommendation. I am an advocate of adding (or top-dressing) fat (i.e. oil) to the diet as a fuel source. In addition, there are occasions in which I will recommend adding beet pulp to a horse's diet for the additional benefits of promoting "gut integrity". So, if you want to add energy to your horse's diet, feed a balance formula but the formula you need does not have to be loaded with corm, barley or rice bran. Our Integrity Growth would be my recommendation for this age and beginning training level.


Integrity Adult/Senior is the choice I would suggest for your working mare. This formula contains less fat and the ingredient panel's differences with your current feed are an important factor. The intensity of working bouts, the amounts of feeds (weights) and the mare's estimated body weight would be helpful in order to provide you additional feeding guidelines.

The commercial product you are now feeding contains 12% crude protein, 15% crude fiber and 12% crude fat. The first 4 ingredients of your textured feed are beet pulp, cane molasses, whole oats & oil. High fat feeds, such as this one (8% and higher), have their place with horses that are working at the intense to heavy levels of competitive performance or during the first 10 weeks of lactation. However for light to moderate working horses (which I am assuming your mare is in that range), I prefer a balanced formula that is 4 - 7% crude fat and has more variety in the Ingredient panel before the molasses ingredient shows up. Molasses is the 2nd ingredient in the formula you are feeding. The amount of molasses in a texture feed can vary from as low as 3% to as high as 16%. Since ingredient panels list feed quantities of the formula in descending order then molasses is the 2nd ingredient in total weight in that formula. Molasses is NOT one of the ingredients I want to see in the first 4 ingredients listed.

In Integrity Adult/Senior the first four ingredients are beet pulp, soy hull pellet, soybean meal & rice bran. Molasses is the 6th ingredient. This Integrity formula's guarantee analysis is 13% crude protein, 6.5% crude fat and 16% crude fiber. The 6.5% fat content of this formula is for a very good reason. Fat is an excellent source of fuel and also is an alternative to high starch grains. My approach is that if a horse needs more energy via fat during periods of more intense workouts then I can just add (top-dress) oil to the amount being fed.

One of the benefits with oil is that unlike other feedstuffs oil provides fat, an energy feedstuff that does not contain other nutrients that when top-dressed would adversely influence the nutrient content of the original formula. If a horse needs more or less fuel for work then the flexibility of when to add or reduce the energy via oil does not significantly alter the amounts of feed being fed and does not adversely influence the levels of nutrients being fed. In other words, minimizing the type of feed changes that have the potential of influencing the gut environment unfavorably. Next to meeting energy & nutrient requirements, my number one goal in feeding horses is taking care of gut integrity thus consistency is important.


I am reasonably confident that the feed is not the issue. The only grain in Integrity Adult/Senior is oats – and there’s very little considering it is the sixth ingredient in the formula. Additionally, Adult/Senior is one of the lowest sugar/starch balanced formulas on the market, second only to Integrity Lite. There are a multitude of factors that influence a horse’s attitude that are not related to feed. They could be a change in routine or exercise program; change in weather, confinement, paddock routine, or equipment.

For the amount of work and food supply, your OTTB should be able to maintain body weight. Nevertheless, if the BCS is a 4 then you need to add calories or distribute the calories in smaller meals. You may consider feeding three times per day so that there are smaller meal sizes. Older horses tend to have a faster gut mobility once it enters the gut. There are number of physiological/genetic reasons for this response but experience suggest smaller meals maybe helpful.

The dislike for orchard may be a preference issue rather than a dislike for orchard grass. Some horses fed alfalfa along with grass hays will consume the alfalfa and other feeds first and leave the grass hays to the end when their appetite seems fulfilled. You may want to substitute one of the orchard flakes with a grass hay pellet and mix the hay pellet with the Integrity Adult/Senior. In addition you can add 1 lb of rice bran or ½ cup of a vegetable oil per day; you will need to divide the additional fat between at least two of the meals. The fat additive is just a fat source and the amount you are feeding will not equal the calories via rice bran or oil. Most likely cheaper as well. I understand the omega-3 fatty acid “talk” but we are feeding a non-ruminant herbivore, not an omnivore or carnivore where the relationship of omega 6 to omega 3 is important and has been demonstrated scientifically. In the wild or pastured only, the dietary daily fat is less than 3%, so not an issue unless feeding a total diet that of 12 - 15% or higher; …that’s total diet which includes the forages fed.

One last consideration, assuming you are bolus deworming. With horses that have difficulty with gaining weight, I have seen positive results switching to a daily dewormer (will still need a boticide twice a year). The lower level of pyrantel tartrate also is available in generic form which is less expensive than the brand name.

I would try these suggestions before increasing the Integrity Adult/Senior from 5 to 6 lbs. If you follow your proposed work schedule then 6 lbs/day world not be too much but let’s see if the addition of fat and replacing hay with hay pellet adds the extra calories for the weight gain. Within 3- 4 weeks you should be able to see a difference.
