Lungworm is not picked up using faecal egg counting, so it is vital to check calves regularly and to look out for signs of coughing. Contact the vet immediately if any coughing is heard

Insecticide impregnated ear tags, tail bands, pour-on, spot-on and sprays containing pyrethroids can help reduce fly annoyance

By

If concerned about de-wormer treatment failure, check faecal egg counts 14 days post benzimidazole (1-BZ) or ML (3-ML) treatment. Speak to the vet or SQP about this

By

Where calves are grazing infected pasture and testing indicated a need for treatment, do not move them to new pasture immediately after. If they must be moved, leave 10% of the heaviest stock untreated

By

Graze youngstock on hay and silage aftermaths as they become available, as these fields will have a low parasite burden.

All-group treatments provide strong selection pressure for anthelmintic resistance. An alternative is to take an evidence-based approach and give anthelmintics on information obtained from growth monitoring and faecal egg count (FEC) analysis. Assess the risk with your vet

By

Summer is a good time to use faecal egg counts (FECs) to monitor gut worm infection in first and second season grazing calves. Assess condition and weight gain and provided nutritional needs are being met, consider further investigation of calves are failing to thrive. If FECs come back positive, but below the 200 eggs/gram threshold for treating, test again in two to three weeks, as FECs can rise quickly in July and August

Giving an early season de-wormer ensures that few gut worm eggs are shed up to mid-summer, by which time any overwintered gut worm larvae present, will have died

Anthelmintic treatments can be administered to calves strategically during the first half of the grazing season to counter gut worm infections. The frequency of treatment depends on the persistency of the product used – speak to your vet or SQP about this
