Drenching tips for Calf Rearers

Drenching tips for Calf Rearers
As with anything there are a few golden rules that everyone should follow to ensure that the job is done right.

  • Never drench calves at the calfeteria or mix drench with milk. Most oral drenches require slow absorption from a rumen depot for effectiveness – adding to milk prevents this happening because sucking milk causes closure of the oesophageal groove, then the milk bypasses the rumen and goes straight to the abomasum or fourth stomach.

  • Oral white and clear drenches are the best for calves (oxfen and levamasole). Calves that are under 120kg cannot have Abamectin drenches. Check the label instructions if you are unsure.
  • Determine if they actually need drenching at all with a faecal egg count and faecal coccidial count.

  • Always check that the drench gun is measuring accurately and that the dose is correct. Weigh enough animals to get an accurate weight. Issues can arise with either underdosing or overdosing. You need to drench to ensure the heaviest animal is accurately dosed. If there is a large weight range in the group then you need to split them and give a heavy and a light dose.

  • Never swap drench containers. If decanting to a smaller drenching container always write on container or transfer back to the original container when finished. Double check the correct product is being used.

    If you have any questions around drenching your calves, contact your Anexa Vet or local Technical Support Representative.
