Fibre (hay, haylage and pasture) should ALWAYS form the basis of any horse’s diet. It is often overlooked and a lack of fibre will increase the incidence of gastric ulcers, wood chewing, loose droppings, loss of weight and irritability. Additionally, fibre in the hindgut traps water and electrolytes and helps to combat dehydration and research shows that diets high in fibre resulted in increased water uptake.It is currently recommended that performance horses should receive a minimum of 1% of their bodyweight (BW) per day of forage to satisfy its requirements for long stem fibre and to minimize digestive upsets, although ideally forage intake should be in the region of 1.5 - 2% of BW and more if you are feeding haylage. For example a 550kg horse should ideally be fed 8.25 – 11kg of hay and at least 11kg haylage per day.Many feed companies offer a forage analysis service for a small fee and this enables a more accurate feeding programme to be devised based on the nutrient value of the forage. I also recommend that for a period of time that you weigh your forage and also any leftovers to establish what your horses actual fibre intake is. This can often help to answer any problems related to loss of body condition or loose droppings.
PERFORMANCE HORSES, TRAVELLING AND GASTRIC ULCERS
Travelling and competing can mean that horses go for prolonged periods without anything to eat. This leads to a build up in gastric acid in the stomach and increases the incidence of gastric ulcers, which will reduce performance. When travelling and competing allow your horse to regularly graze or pick at a haynet to stimulate saliva production. Alfalfa is a natural antacid, so frequent bites of alfalfa-chaff will help to neutralize excess stomach, especially if fed 15 minutes before riding.
If gastric ulcers are a concern ask a Saracen Nutritionist about the use of equine digestive supplements such as KERx Rite-Trac™.
WHAT DOES YOUR HORSE WEIGH?
Regularly monitor and record your horse’s body weight and body condition score. This enables you to accurately calculate your horse’s nutritional requirements for performance and can help you to achieve optimum competition body weight or ‘fighting weight’.
There are now increasingly more performance diets available to meet the nutritional requirements for horses performing in specific disciplines, such as Enduro-100 for endurance horses or event horses. For power based exercise such as show jumping and dressage, feeds will often need to have more emphasis on providing energy from starch based ingredients, such as oats and barley etc. For stamina work such as endurance or eventing, there will be a greater reliance on digestible fibre sources, such as soya hulls, sugar beet and oil, balanced with enough cereal and starch to ensure that muscle glycogen stores remain ‘topped’ up.
Feeds are formulated to provide your horse with optimum nutrition when fed at the recommended quantity. Make sure that you weigh your feed to ensure correct intakes; don’t just assume that one scoop hold 1kg of feed, as this is often not the case! If you need to feed below the manufactures recommended levels to help manage body condition use a feed balancer, for example Essential Balancer or Stamm 30®, or a broad-spectrum vitamin and mineral supplement to provide adequate levels of vitamins, minerals, quality protein and important antioxidants such as vitamin E and Selenium.
One of the most frequently asked questions concerns the timing of feeding the performance horse. Concentrate feeding alone should be avoided for at least three hours before heavy exercise to allow for increases in blood glucose and insulin to return to baseline levels. Feeding small amounts of forage or limited grazing time prior to exercise will moderate body weight and does not appear to have any other adverse effects to performance and can in fact help to support optimal digestive health when competing.
SALT AND ELECTROLYTES
Apart from water and energy, salt is the only mineral that horses have an undisputable appetite for. In addition to a correct electrolyte supplementation programme, a salt lick should be provided and at least 2 - 3 ounces of salt added to the feed per day.
Electrolytes are a critical component of a performance horse’s nutritional programme since they play an important role in maintaining osmotic pressure, fluid balance, and nerve and muscle activity. During exercise, sodium, potassium and chloride are lost in large quantities through sweat. Loss of these electrolytes causes fatigue and muscle weakness and decreases the thirst response to dehydration. It is vitally important that performance horses begin competition with optimal levels of fluids and electrolytes in their bodies and that these are replaced throughout prolonged exercise with the use of supplements such as KERx Restore SR.
Electrolytes are often misused and it is essential that horses have access to unsupplemented drinking water when administering electrolytes. If the horse refuses to drink, do not administer an electrolyte paste or supplement as this can make the horse more dehydrated. It is well worth a phone call to a nutritionist to advise on a correct electrolyte programme to ensure optimum performance and to reduce the occurrence of problems such as premature fatigue or muscle issues, such as 'Tying-Up'.
Travelling, even short journeys cause all horses some degree of stress, even in well-seasoned travellers that do not display any signs. After travel muscle enzymes are often raised, which can result in muscle soreness, and stress hormone levels are also often elevated which can have a negative effect on the horses immune function. To help combat this for horses that travel and compete often we suggest adding additional anti-oxidants into the ration. Anti-oxidants help to maintain immune function and also support the cardiovascular, circulatory, neuromuscular, and reproductive systems.
Horses that regularly travel can use up their stores of anti-oxidants relatively quickly during travel and recovery, and it can take a long time to build these levels back up again, which can result in a lack of energy and decrease in performance levels. The most important anti- oxidants in the horse’s body are vitamin E and selenium. As compound fees contain a good level of selenium we would not advice adding additional selenium into the ration as horses can easily suffer from selenium toxicity. However we often suggest adding an additional vitamin E supplement into the ration, as, unlike selenium, there is no known toxicity level for vitamin E in horses, and horses that regular travel often benefit from additional vitamin E supplementation.
When supplementing with Vitamin E look for a natural form, such as KERx Nano-E. Many vitamin E supplements on the market are use synthetic vitamin E. Natural vitamin E supplements are more easily taken up by the horse and is also retained in the tissues for longer than synthetic vitamin E. KERx Nano-E can be used on a strategic basis for a couple of days before travel, the day of travel, and for a couple of days after travel. This will help to boost the anti-oxidant levels in the body, helping the horse to recover from travelling quicker and helping to support optimal energy levels.
Finally, whatever level it is that you are competing at, remember, WATER, FORAGE, TRICKLE FEEDING, WEIGHTS and don’t hesitate to ask for advice from your vet or nutritionist.
