Keep It Simple Diet

The basics needs:

  • Roughage – approximately 70 % of the horses feed should be in the form of roughage (hay, pasture or chaff).
  • A salt lick (Himalayan rock salt is a great option as it doesn’t contain any additives).
  • Water at least 30ltrs a day in cool weather for full size horses and double in hot weather or heavy workloads.
  • Minerals and Vitamins to meet dietary needs

 The volume feed needed can be worked out as:

1.7 (% of bodyweight) x 500 (kg horse) = 8.5 kg max feed
100
(In this example the horse weighs 500 kg, so it can safely consume up to 8.5 kg of dry feed per day.)

Base Feeds

The truth about carbohydrates

 Most grains are high in the polysaccharide carbohydrates of sugar and starch (NSC).  This type is connected with metabolic disorders.

Feeds such as beet-pulp, lupin and copra by com-parison are high in the fibre type polysaccharide carbohydrates.

Issues with feeding grains

During the digestive process, both sugars and starches are turned into the sugars.  Horses have a limited capacity to digest substantial amounts of sugar and starch in the stomach and small intestine.  The excess supply of sugar and starch travels through the small intestines and on into the hindgut where the trouble begins.  An increase of sugar fermentation creates lactic acid.  Lactic acid lowers the pH causing an acidic environment, this in turn kills off the good microbes.  The dead microbes give off endotoxins that now enter the blood stream, this chain reaction often culminates in poor gut health, ill thrift (or obesity) and potentially laminitis.

Benefits of feeding Copra, Beet-Pulp and Lupins

Copra, Beet pulp and Lupins are rich sources of ‘super fibre’ type of polysaccharides.  These super fibres have a high water-binding capacity (viscosity increases from the presence of fibrous polysaccharides).  The fibres carry volumes of water and nutrients un-digested through the small intestines and on into the hindgut (large intestine) to release their nutrients and feed the good microbes such as Clostridium, Bifidobacterium, Lactobacillus, Staphylococcus, Enterococcus, Streptococcus, Enterobacter and Escherichia hence stimulating colonization of intestinal microflora.

Fibre types of Polysaccharides provide sustainable energy (slow release energy) and help stabilize blood sugar levels (reduction in glycaemic response).  Polysaccharides fibre have also been claimed to increase the amount of feel-good chemicals in the brain, decrease gastric emptying, increase satiety, improve immune system health and assist liver function.

Feeding: Foals through to Young Horses

 By The Nude Horse
(Equine Epidemiologist)

Ideally a foal will suckle within 20 minutes to 3 hours after foaling and readily take in the 15% of the immunoglobulin concentrates of colostrum.  During the following 7 days of life a foal should suckle approximately 7 times every hour each suckle lasting 1-2 minutes. As the weeks go on, the frequency reduces to about 3 times per hour.  From a mare fed nutritionally balanced feeds, the milk bar will provide all the necessary nutritional needs of foals for the first 6-8 weeks of age.  Within days of foaling a young horse will likely begin to sample the grass, hay and hard feeds in their environment, increasing as milk concentration and production decreases.

Foals are dependent on enzymes to break down nutrients in the gut.  Young foals start with high levels of lactase, an enzyme that digests milk.  Adult horses depend on their gut microbes to ferment and release the nutrients from fibre in forage (soluble fibre).  Young horses typically source these gut microbes from grazing on pasture grasses.  For this reason, foals are often seen eating their dam’s manure, a rich source of fibre fermenting bacteria.  From 3-4 months of age, the young gut can begin to digest concentrates in hard feeds, this is the time to begin feeding the foal their own small hard feed.  A common method is for the foal to have access to their own smaller feed portions in an area the mare cannot enter, known as a creep feeder.

Research shows foal health and skeletal development begins in the prenatal phase

Of interest copper supplementation of dams in late gestation may be protective against articular cartilage abnormalities/lesions in foals2, prevention of skeletal problems3 and a significant reduction in physitis score (swelling around the growth plates in young horses).4

White muscle disease has been attributed to selenium deficiencies from in gestation.  WMD is characterized by myopathy resulting in weakness, impaired locomotion, difficulty in suckling and swallowing, respiratory distress, and impaired cardiac function.  Selenium deficiencies can increase when a pregnant mare consumes high levels of unsaturated fats (vegetable oils.) 7 Selenium deficiency has been suggested to be involved in some cases of flexural deformities.  Janicki et al. reported that foals from mares fed 3 mg per day had higher concentrations of IgG at 2, 4 and 8 weeks of age than foals from mares fed 1 mg or less of selenium per day.6 Organic forms are shown to be more effective (Pagan et al).

Vitamin E has received considerable attention in recent years as a powerful antioxidant that reduces free radical activity. Vitamin E helps maintain membrane integrity in virtually all cells of the body. It also enhances immune response.

A study by Hoffman et al. reported that mares fed a minimum 160 IU of Vitamin E per kg of feed during the periparturient period had higher serum immunoglobulin G concentrations (IgG) than mares fed less.   Suckling foals of mares fed the higher concentration of vitamin E had higher serum concentrations of IgG than foals of mares fed 80 IU per kg of feed.8

During the last trimester of gestation, two-thirds of fetal growth occurs and 85-90% of fetal calcium is accreted from the mare into the fetal bones.  The pregnant mare should be fed a diet containing 0.45% calcium and 0.3% phosphorus.  Protein requirements should also increase by 10% (NRC).  Poor nutrition before and after foaling have been implicated in stress and early embryonic death.

Progesterone is critical to the maintenance of early pregnancy.  Holtan and Hunt (1983) reported a positive relationship between dietary protein and progesterone concentrations.

How Much Do I Feed?

Meeting your horse’s daily dietary needs is actually very simple.  First, rate the horses body condition, then work out their estimated weight.  Reaching their idea weight/body condition is then a matter of either increasing base feed volumes or continue feeding at daily recommended feed rates until ideal condition is met.

Calculate estimated body weight

[Girth (cm2 ) × length (cm)] ÷ 11 000 = Weight

 

For example:

Girth of 190cm (square this) =36100

Then 36100 x 125cm (length) = 4512500

Then 4512500 ÷11000 = 410kg.

This is an estimate only and could be 50±kg.

 Maintenance daily feed requirements

Formula: Multiply 1.7 x estimated horses weight then divide by 100.  Example 1.7 x 410 (kg)= 697, so 697/100 is 6.9kg.  Meaning you need to provide 6.9 kg of dry weight feed daily to a horse weighing 410kg.

Hay/grass/chaff should make up at least 70% of the daily diet. A 410kg horse, for example, in maintenance mode feed at least 4.8kg dry weight of hay/grass per day PLUS a hard feed (dry weight) a maximum of 2.1kg to make up the daily feed requirement of 6.9kg in this example. The hard feed can of course be less if the roughage is increased to compensate.

Oils - the good and the bad

Along with ‘sugars’, the debate on what oils are actually bad and what are good is possibly the most contentious topic in the nutritional industry this century.

Why the belief that saturated fats are bad:

Diet professionals have slammed ‘saturated fats’ as the cause of heart disease in humans from as early as 1912.

From as early as 1912 Russian Scientist, Nikolai N Anichkov announced his discovery that saturated fats were the ‘primary factor’ of induced atherosclerosis (plaque that builds up inside the arteries).  Nikolai tested vegetarian rabbits with egg yolks and purified cholesterol added to their diet.  What he did not disclose is this:  Anichkov fed his rabbits cholesterol dissolved in vegetable oil (polyunsaturated oil).1

Could health professionals be so wrong?

Consider the rise and fall of trans fats. From the 1970’s they were used in everything from cakes, cookies, breads, snack foods, deep fryers, movie popcorn, chips, restaurant foods, salad dressing etc.  The food industry promoted trans fats as ‘healthy’.  The Life Science Research Organization of American Societies for Experimental Biology declared trans fats to be safe for consumption.

 Only in recent times have trans fats been exposed as dangerous for consumption from data revealing trans fats contribute to cancer and heart disease.4

...A 1994 study estimated that over thirty thousand heart disease deaths per year in the USA are attributed to the consumption of trans fats.5

...More bad news

Heating at such high temperatures creates dangerous free radicals and aldehydes and neutralize or destroy any beneficial antioxidants such as vitamin E.

....The industrial processes to create vegetable oil damages the extracted fats and makes them unstable and rancid right from processing (rancid smells hidden by the deodorizing step), when consumed free radicals enter the body.

Electrolytes - what you need to know

Did you know a horse not in work loses up to 10 litres a day in sweat! That means losses of 10 grams of Sodium, 10 grams of Chloride, 25 grams of Potassium and 10 grams of Magnesium!

A horse in mid-range work sweats by comparison 27-43 litres a day.  That means losses of up to 43 grams of Sodium, 71 grams of Chloride, 43 grams of Potassium and 13 grams of Magnesium.

The horse’s body cannot retain water without the presence of electrolytes.  Adding electrolytes to the horses feed helps replenish the lost fluid.  However, after prolonged sweating it will take several days of electrolyte supplementation to completely replenish losses.  Hence supply of necessary electrolytes should continue.

Critical attention needs to be adhered to on how to sustain and replace electrolytes.  Sadly, some recommend loading hard feed with salt.  Is this safe or even necessary?

Studies consistently demonstrate sodium chloride (salt) should be available for the horse ad lib in the paddock/stables all year round in the forms of either plain iodized, cobalt-iodized or trace-mineralized salt (Himalayan Rock – often the easiest choice).  Research indicates a horse will naturally uptake only 0 to 62mg/kg BW/day*.  (Example: a 500kg horse would uptake naturally between 0 gr a day to a maximum of 31 gr by free choice).  Common sense dictates adding more than 31 gr a day to hard feed (including what is already available in their feeds/supplements) would be unnecessary and even dangerous in consideration of Holbrook et.al., 2005 ‘repeated oral administration of an electrolyte solution has been associated with an exacerbation of gastric ulcers.’

Fatty Acids - Omega 3 & 6

What is the difference

We hear a lot about the three Omega 3 fatty acids Alpha Linolenic (ALA), Docosahexaenoic acid (DHA) and Eicosapentaenoic acid (EPA).  But did you know there are many more?

Mammals are unable to synthesize omega-3 fatty acids.  Supplement feeding has taken popularity with the plant based omega 3 ALA found in Flaxseed, but only a small amount as low as 5% is actually converted into the necessary EPA and DHA. Fish oil (Cod Liver Oil) & Hemp Seed Oil on the other hand provides pre-formed ready to be utilised EPA and DHA Omega 3s in the right ratio.

Surprisingly for some, Pasture grass naturally offers a ratio of 1:4 (Omega6:Omega3) it simply can’t be beaten as the best source for your horse.  When pasture is unavailable, then it is recommended by Kentucky Equine Research to supplement 60 ml/day of fish oil. (Pagan, Lawrence, Lennox).

We hear about the excesses of omega 6 fatty acids in the diet.  High proportions of Omega 6 to Omega 3 fat in the diet shifts the physiological state in the tissues toward pathogenesis of many diseases. Omega 6 increase inflammation.

 

Animal feeds high in Omega 6 throw the correct dietary ratio out of balance.  Feeds that are proportionately too high in Omega 6 to Omega 3 are vegetable oils (soybean, cotton seed, sunflower seed, corn, grapeseed, rice bran, peanut, sesame oils) Corn oil for example has an omega 6 to omega 3 ratio of about 45:1!  Caution too with seeds like sunflower, sesame & pumpkin along with grains including corn, oats, wheat, quinoa and rice, not to be missed are legumes like soybean and peanuts that are very high in the Omega 6 fatty acids.

....Fortifying your horse’s diet with an omega 3 of at least 2-5 to 1 of omega 6 provides key health benefits.  A healthy diet low in Omega 6 and high in Omega 3 (being naturally anti-inflammatory) can help reduce allergy symptoms.  Research indicates these additional health benefits of increased Omega 3 uptake....
