Information on Worms in Calves
Worms will cause problems in calves, young cattle and even sometimes older cows if steps are not taken to control them.
These drugs are available in injection and/or pour-on formulations.
Other drugs are available and may be more suitable, subject to veterinary advice.
From Vet.Record March 28, 2015
In the UK, in dairy cattle, the choice of drugs is limited to albendazole and oxyclozanide (milk withhold 60 hours & 72 hours respectively), with neither drug being claimed to be effective against flukes in animals below seven to 10 weeks of age. Triclabendazole can be applied to cattle at dry-off (e.g. Endofluke milk withhold 45 days dry plus 48 hours)
In beef calves treated housing, shedding of fluke eggs was monitored. It took 8 weeks following Clorsulon, 13 weeks following nitroxynil , for eggs to reappear in the dung. In this trial, eggs did not reappear in the triclabendazole treated calves.
Other drugs may be used and may be more applicable. e.g. Closantel in Closamectin.
