Water Soluble Powder Containing Essential Electrolytes

Dietary Electrolyte Balance (DEB) is an important factor for many animals. Two thirds of the body is water. The body fluids carry oxygen and carbon dioxide, move nutrients to the tissues, remove waste and distribute enzymes and hormones to their target tissues. To function efficiently, body cells require electrical energy and must have a constant, balanced environment which is provided by the fluids surrounding them. Water is a poor conductor of electricity, however electrolytes carry an electrical charge and ionise when added to water making them a powerful conductor of electricity.

Increases in deep body temperature from hot and humid environments can result in electrolyte imbalance, affecting appetite and increasing metabolic rate. The body responds to restore electrolyte balance (homeostasis) directs energy away from productivity toward heat loss. Selectolyte contains Bicarbonate (HCO3-), Sodium (Na) and Potassium (K) ions to restore dietary electrolyte balance.

Bicarbonate (HCO3-) acts as a buffer to assist in the maintenance of acid-base balance. Sodium (Na) makes up 2% of total body weight and occurs in the fluids around cells where it assists in the maintenance of osmotic pressure. Sodium (Na) is involved in multiple enzyme pathways, including the activation of enzymes responsible for the absorption of glucose and other nutrients from the gut and kidney. Potassium (K) is found inside the cells and is also involved with enzyme systems and is essential for the flow of electrical impulses along the nervous system. 

Selectolyte assists to restore dietary and electrolyte balance (DEB) in animals’ suffering from an elevated body temperature, due to environmental conditions, disease or other stress factors. Optimal DEB is important to ensure the maintenance of deep body temperature and efficient metabolic function.

Selectolyte is an easily applied water-soluble powder for use in drinking water, feed or as a drench. Selectolyte is a feed additive suitable for all types of livestock, including poultry, pigs, dairy cattle and calves. 

Selectolyte is an efficient product for replacing important dietary electrolytes lost in animals due to environmental stress factors that cause dehydration. Selectolyte is shown to be an effective solution for reducing stock losses in animals under these harsh or stressful conditions.

The product restores the dietary electrolyte balance (DEB) in animals suffering dehydration due to temperature extremes, disease, and other animal husbandry conditions. Maintenance of optimal DEB is important for animal growth and production performance. Selectolyte does not contain any additional chloride.

Easily applied and fully water-soluble, Selectolyte may be used in drinking water, in feed, or as a drench. It is suitable for all types of livestock including calf, dairy cattle, pigs, and poultry. Selectolyte does not cause sedimentation and therefore will not settle at the bottom of medication tanks or clog nipple drinkers.


Heat stress is the major cause of production loss and lost profits in poultry, swine, dairy and beef cattle industries.
Selectolyte promotes recovery from heat stress caused by the extremes of high temperature and humidity, disease and other husbandry conditions, such as:

Stress from Transportation

Animal transportation is a necessary part of farming. Animals can become stressed and dehydrated due to the processes involved. Selectolyte assists animals to recover from the impact of transportation.

Crowding or Poor Ventilation

Overcrowding or poor ventilation are common causes of livestock stress and potential electrolyte loss. The effects of electrolyte loss can be relieved by the use of Selectolyte feed additive to restore electrolyte balance.

Vaccination Recovery

Stress, due to elevated body temperature and dehydration, can be a side effect of livestock vaccination. Restoring electrolyte balance can assist with recovery.


Disease Recovery

Outbreaks of disease are common in the livestock industry. Optimal electrolyte balance assists the animals' physiology and helps restore and maintain animal wellbeing.

Thermal Stress

Thermal comfort zone for most animals is between 4°C and 25°C. Thermal stress in hostile environments, where animals are outside this "Zone of Comfort", are responsible for losses in animal production. This is especially prevalent in poultry production.

Poultry Specific Issues

Stress through debeaking may cause electrolyte loss and lead to dehydration in poultry.

Dehydration and increased body temperature occurs as a result of a variety of factors.
In these situations, it is important to restore the electrolyte balance in order to ensure optimum physiological function.

Product is suitable for:

Animal Types Description
Pigs Weaners, growers, finishers, sows and boars.
Poultry Broilers, layers, ducks and breeding birds.
Dairy cattle Lactating cows.
Calves Both dairy and beef.
Other ruminants and livestock Beef cattle and calves, sheep, goats.

How Selectolyte Works

Selectolyte is recommended for the restoration and maintenance of the dietary electrolyte balance (or “DEB”). The DEB is typically expressed as milliequivalents (mEq) of Sodium (Na) plus Potassium (K) minus Chloride (Cl). 

In conditions of high temperature and humidity, the DEB requirement often cannot be achieved through consumption of feed. In these conditions, animals have difficulty maintaining deep body temperatures and will be less productive.

Selectolyte is a free-flowing, water-soluble alkaline electrolyte powder containing high levels of the key dietary electrolytes, Sodium (Na), Potassium (K) and Bicarbonate (HSO3). Selectolyte is a feed additive that assists in restoring the DEB and acid-base balance to restore normal physiological function.

Note: Selectolyte does not contain added Sodium Chloride (NaCl) or Potassium Chloride (KCl).
