Fevertreat Plus

It Contains calcium and magnesium especially formulated for high lactating cows.

Hypocalcemia and milk fever in high lactating cows could cause extensive economic loss in the herd. High lactating cows with subclinical hypocalcemia are always at risk of falls, pelvic bone fractures, and premature removal from the herd. Scientific studies have shown that besides calcium deficiency, this group of cows are also exposed to magnesium deficiency with muscle spasms, respiratory problems and possible eventual death.

Magnesium deficiency is the second most common cause of hypocalcemia and milk fever in fresh cows. Magnesium deficiency affects the release of calcium during calving in the animal body in two ways:

  1. It affects parathyroid hormone receptors and reduces their sensitivity to calcium release
  2. Reduces parathyroid hormone secretion in response to hypocalcemia.

Magnesium and phosphorus deficiency comorbidity complicates the condition more so. Blood magnesium concentrations less than 2 mg /dl in the first 24 hours after calving indicates insufficient magnesium absorption.

Drinking calcium supplements increases the risk of respiratory problems due to damage to the upper respiratory tract. Injection of calcium supplements also has a temporary effect and increases blood calcium levels only for a short time. Therefore, the best advice for this group of cows is to consume edible bolus containing different sources of calcium with different release rates and in the form of organic chelates as well as magnesium, which in addition to preventing milk fever, also eliminates the effects of calcium and magnesium deficiency.




  • The wax coating of the bolus prevents release of calcium and magnesium in the mouth. This mechanism avoids possible damage to the upper respiratory tract.
  • The bolus cover dissolves rapidly in the rumen environment and calcium and magnesium continuously absorb into the bloodstream for 48 hours.
  • Three boluses with a diameter of 2.5 cm and a length of 10 cm, gradually provide 62.4 grams of calcium and 7.2 grams of pure absorbable magnesium to the animal.
  • Consumption of the bolus maintains optimum level of calcium and magnesium in the blood for at least 48 hours.


Pure calcium & magnesium per bolus
Fast release calcium 16.6 gram
Medium release calcium gram 3.6
Chelated calcium 0.6 gram
Magnesium 2.4 gram




Feed two boluses simultaneously with the first signs of calving, and the third bolus 24 hours after to maintain a proper level of calcium and magnesium in the blood for about 48 hours.


Instruction for cattle with milk fever

Always consult your veterinarian. After injecting calcium supplement, allow the animal to go back to normal standing stance. Examine swallowing condition and ensure there are no challenges for the animal. Begin with two boluses and 24 hours after the first intake, feed the third bolus.

Avoid the bolus if clinical signs of milk fever exists. Difficulty in swallowing increases the risk of apnea. Use a bolus-eating gun to feed the bolus.



  • Store in a cool, dry place below 25 ° C.
  • Do not use a bolus when milk fever is diagnosed. With milk fever and possible swallowing difficulties, bolus application may lead to animal suffocation.
  • Use a bolus-eating instrument to feed the bolus.
