Prolyt Pack® Extra
Calves suffering from diarrhoea need to quickly compensate for fluid and electrolyte losses to  prevent metabolic acidosis. 
ProlytPack® Extra provides exactly the right electrolytes to rehydrate calves experiencing scour

Oral rehydration in calves 

Many causes—one result 

Diarrhea in calves is not a single disease. Rather, it is a manifestation of the many infectious and non-infectious causes associated with it. From the moment of calving, a new born calf is exposed to numerous pathogens—bacteria, viruses, parasites, protozoa—all of which harm the intestinal tract and cause diarrhoea. The most common bacteria responsible for diarrhoea are E. coli, Salmonella, and Clostridium perfringens; viral and protozoal causes include rotavirus, coronavirus, bovine viral diarrhoea virus, cryptosporidium, and coccidia.  

Non-infectious causes of calf diarrhoea include inadequate nutrition, unsanitary pens, overcrowding, and inadequate colostrum intake. Colostrum intake is crucial for passive immunity and the development of a functioning immune system. Lack of colostrum feeding increases the risk of various infections and causes a higher sensitivity to environmental pathogens. Ensuring sufficient colostrum intake is vital for future health. A calf should drink at least 3–4 litres of good-quality colostrum within the first four hours of life. 

Metabolic acidosis—the next phase 

In calves, metabolic acidosis is a common result of diarrhea-induced dehydration. Without treatment, metabolic acidosis is a prime factor in the death of many of these calves. Early and intensive oral electrolyte therapy at the onset of diarrhea in calves is critical to replenish fluids and correct metabolic acidosis. Therapy should be started as soon as possible regardless of whether evidence of dehydration is seen. The clinical signs of dehydration are not obvious until the calf has lost at least 6% of its body weight in fluid (figure 1). The course of therapy depends on the severity of symptoms. Calves still able to stand and suckle can often be treated with oral rehydration solutions alone to avoid continued fluid losses and restore extracellular cell fluid volume. If there are signs of systemic illness, a veterinarian should be consulted for additional therapies such as anti-inflammatories or intravenous fluids.  

Many electrolyte products cannot be combined with milk.

  • Prolyt Pack® Extra can be mixed with milk. Easier for the farmer and better for the calf

The ingredients in some electrolytes particularly sodium bicarbonate can interfere with the coagulation of milk in the calf. These products should not be used at the same time as feeding milk.

Using Prolyt Pack® Extra allows the calf to continue digesting milk as nature intended and using lactose as the energy source.

  • Prolyt Pack® Extra rehydrates but also includes organically bound zinc and betaine from sugar beet molasses which support the quick regeneration of damaged gut mucosa. Betaine improves cell water hydration by its osmolyte function.

  • Prolyt Pack® Extra is outstanding value for money. 1 litre of Prolyt Pack® Extra feeds 20 calves
