Indications
In newborn calves, Halosan Oral is indicated for:
- Prevention of diarrhoea due to diagnosed
Cryptosporidium parvum, in farms with history of
cryptosporidiosis, with administration to be
started in the first 24 to 48 hours of age.
- Reduction of diarrhoea due to diagnosed
Cryptosporidium parvum, with administration
to be started within 24 hours after the onset of
diarrhoea.
Contra indications
Do not inject.
Do not use Halosan Oral on an empty stomach.
Do not use in case of diarrhoea for more than 24 hours and in weak animals.
Side effects
In very rare cases, an increase in the level of diarrhoea has been observed in treated animals. Besides diarrhoea, symptoms of toxicity include visible blood in faeces, decline in milk consumption, dehydration, apathy and prostration. Should clinical signs of overdosing occur the treatment must be stopped immediately and the animal fed unmedicated milk or milk replacer. Rehydration may be necessary.
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
For oral use in calves after feeding.
Calves 35 - 45 kg:
8 ml once a day for 7 days.
Calves 45 - 60 kg:
12 ml once a day for 7 days.
Lighter or heavier calves: 1 ml per 5 kg (100 µg/kg) once a day for 7 days.
Use after colostrum feeding, or after milk or milk replacer feeding only. Due to toxic potential it is crucial to strictly adhere to the prescribed dose rate. Use either a syringe or any appropriate device for oral administration to ensure the correct dosage. Consecutive treatment should be done at the same time each day. Once the first calf has been treated, all the forthcoming newborn calves must be systematically treated as long as the risk for diarrhoea due to C. parvum persists.
Withdrawal times
Meat and offal: 13 days.
