Electrolytes are mineral ions dissolved in bodily fluids such as tissue fluid and blood and can bind to another ion to make a 'salt'. They are important for neuro-muscular function, processing waste and preserving the correct balance of fluids in the body's cells. Deficiencies may result in dehydration, impaired performance, early onset fatigue and exacerbate problems such as ERS. Electrolytes are lost through sweating, urine and faeces and are normally replaced by the diet. However, during periods of exertion, electrolytes losses can be considerable and it is in such a case where additional electrolytes should be supplied to compensate for these losses.

Equine Rhabdomyolysis Syndrome is more commonly known as 'azoturia' or 'tying up'. This condition occurs due to the disintegration of muscle cells and particularly affects the hindquarters. The general principles of managing a horse with ERS are to keep the diet as low in sugars and starch as possible and feed a diet high in fibre and oil as alternative sources of energy. More information on how to deal with ERS and muscle related problems.

This form of cooking involves the feed materials being made into a slurry and injected with hot steam. This is then passed through a die (which vary in size and shape) and as it passes through, the drop in pressure causes the material to expand.
