Glycaemic index among horse foods
You have probably already once been used to describe the word "glycaemic index". That buzzword has been circulated for several years among knowledgeable horse breeders, but what does it mean? Even more important, why is it important in horse-feeding? The glycaemic index is a system by which the effect of a given carbohydrate on the level of sugar in the body is graded.
The system pioneered by early 1980s researchers in Canada compared available carbohydrate grams by grams in different feeds and provides a numeric, evidence-based post-meal index of postmeal glycaemia levels of glycosis in the human family. Although the system was initially designed for human use, it has been adapted and approved for horse use.
The highest glycaemic index is found in the carbohydrate, which is rapidly broken down during ingestion. At the other end of the range, those that degrade and release glycose into the blood stream progressively have the lower glycaemic index. Lower glycaemic index indicates lower digestive rates of sugar and starch in food.
If the glycaemic response is lower, the need for lower levels of isolate is expected to result in better long-term glycaemic response and a decrease in the level of fats in the body. Measurements of the reaction of blood sugar and urine in human beings are used to evaluate the influence of dietary factors on diet. Starches were categorized over the whole low to high glycemia and isoline reaction area.
All other foodstuffs were benchmarked against the resulting glycaemic or insulinaemic index using wheat loaf as the default diet. Glycaemic index (GI) of horse feed and animal feed. Oat is used as a dietary ingredient among the usual horse feed. In a given period, a feed with a value above 100 will produce more sugar than oat; a feed with a value below 100 will produce less.
Among the grain usually used for horse feed, oat is the most easily digestible of all. In order to use this know-how in daily feed managment, keep in mind that the best way to keep a horse healthy is to feed it food that can be eaten and eaten well. The reason for this is that their digestion system is designed to cope with small, regular daily feed supplies as if the horse were pasturing.
Excessive strain on the gastro-intestinal system with starches leads unavoidably to peaks in sugar levels, which can lead to difficulties for certain equines. In order to keep fit, certain equines need large concentrated feed. It is interesting that the process of certain grain kernels can change the glycaemic reaction drastically. Low GI rationing is a favourite horse health care tool for diagnosing hypophysis patients with PPID (Equine Cushing's disease), EMS (Equine metabolic syndrome), RER (recurrent excertional rhabdomyolysis), PSSM (polysaccharide store myopathy) and OCD (osteochondritis dissecans).
Although equines with these symptoms all profit from low GI rationing, the most appropriate way to supply the horse with calories will depend on the disease and the horse's diet. PPID equines are insulin-resistant and require a low GI diet, but their power needs may change.
While some can be relatively simple holders and profit from most feed ration, others may require additional calories expressed as fats and fermented fibers. Persons who have been identified with EMS are generally overweight and simple owners and should be mainly supplied with food ration with a suitable, low-inclusion balancing cell.
ECD or EMS are susceptible to hoof deer, which can be caused by accessing juicy pastures, so grazing should be monitored well. Even horse with PSSM and PER and RER can profit from low starches. Grease is an important complement for both groups, but their caloric needs are different. As a rule, PSSM riders need a modest to high level of power, while PSSM riders need fewerories.
OCD risks can be raised by using highly glycaemic feed, but there is no indication that young, fast moving horse need feed with very low glycaemic index. Indeed, a certain amount of strength in the diet is desired in youngsters, especially when preparing for future horse production and sale. Young horse nutrition should have a modest glycaemic index and be enhanced to encourage optimum musculoskeletal performance.
