Indicated for use in newborn calves

  • Prevention of diarrhoea due to diagnosed Cryptosporidium parvum, in farms with history of cryptosporidiosis. Administration should start in the first 24 to 48 hours of age.
  • Reduction of diarrhoea due to diagnosed Cryptosporidium parvum. Administration should start within 24 hours after the onset of diarrhoea.

In both cases, the reduction of oocysts excretion has been demonstrated.

Administer after colostrum feeding, or after milk or milk replacer feeding only, using an appropriate device for oral administration.

Do not use on an empty stomach.

For treatment of anorexic calves, the product should be administered in half a litre of an electrolyte solution.

The animals should receive enough colostrum according to good breeding practice.

Dosage & Administration

For oral use in calves after feeding.

The dosage is: 100 μg of halofuginone / kg bw, once a day for 7 consecutive days; i.e. 2 ml of Kriptazen / 10 kg bw, once a day for 7 consecutive days.

The consecutive treatment should be administered at the same time each day. Once the first calf has been treated, all the forthcoming new-born calves must be systematically treated as long as the risk for diarrhoea due to C. parvum persists.

Bottle without a pump: To ensure a correct dosage, the use of either a syringe or any appropriate device for oral administration is necessary.

Bottle with a pump: To ensure a correct dosage, the most appropriate metering pump should be selected, depending on the weight of the animals to be treated. In cases where the dosing pump is unsuitable for the weight of animals to be treated, either a syringe or any other appropriate device can be used.
