“…For cattle, COWS recommendations are summarized into eight guidelines presented in Table 3 . Learmount et al ( 45 , 46 ) evaluated a 3-years implementation of the SCOPS guidelines on commercial sheep farms in the UK. They found a significant reduction in anthelmintic treatments without loss of animal performance, confirming the effectiveness of such advices in the field ( 45 ).…”

Gastrointestinal nematode (GIN) infections are a common constraint in pasture-based herds and cause a decrease in animal health, productivity and farm profitability. Current control practices to prevent production losses of GIN infections in livestock depend largely on the use of anthelmintic drugs. However, due to the continued use of these drugs over more than three decades, the industry is now increasingly confronted with nematode populations resistant to the available anthelmintics. This emerging anthelmintic resistance (AR) in cattle nematodes emphasizes the need for a change toward more sustainable control approaches that limit, prevent or reverse the development of AR. The uptake of diagnostic methods for sustainable control could enable more informed treatment decisions and reduce excessive anthelmintic use. Different diagnostic and targeted or targeted selective anthelmintic control approaches that slow down the selection pressure for anthelmintic resistance have been developed and evaluated recently. Now it is time to transform these insights into guidelines for sustainable control and communicate them across the farmer community. This article reviews the current uptake of such sustainable practices with a focus on farmer's socio-psychological factors affecting this uptake. We investigate communication as a possible tool to change current behavior and successfully implement more sustainable anthelmintic treatment strategies.

“…benzimidazoles and macrocyclic lactones) ( Höglund et al, 2016 ). Although AR in Sweden is limited from an international perspective, care must be taken to avoid a situation observed for example in the Netherlands, UK and Ireland were the animals can be treated up to eight times per year ( Learmount et al, 2016 , Patten et al, 2011 , Ploeger et al, 2016 ). Thus, the way forward is to keep the use of anthelmintic to a minimum and to deworm only those flocks that require treatment according to the principles for targeted flock treatments ( Kenyon and Jackson, 2012 ).…”

Highlights With microscopy, improved information about Haemonchus was provided on 48% sampling occasions. Haemonchus was diagnosed in 56% of the farms by microscopy and in 75% by ddPCR. There was substantial agreement between the two diagnostic tests. The protocol is a practical tool for sheep producers to assess Haemonchus infection.

“…The SCOPs guidelines incorporate a number of these practices [13]. Recent analysis of the effectiveness of these guidelines in managing parasites while reducing selection for resistance have shown a reduction in the quantity of anthelmintic used and slower development of anthelmintic resistance on farms which adhere to the SCOPS guidelines as opposed to those which follow traditional policies of parasite control while maintaining lamb productivity [32,33].…”

The focus of gastro-intestinal parasite control in the sheep industry is increasingly on finding a balance between maintaining productivity of the flock whilst minimising selection for anthelmintic resistance to preserve anthelmintic efficacy for the future. Periparturient ewes represent the major source of gastro-intestinal parasites for growing lambs and are therefore a priority for parasite control. This study examines the impact on ewe faecal egg counts (FECs), lamb FECs, lamb daily live weight gains (DLWGs) and pasture larval counts of treating groups of ewes two weeks prior to lambing with either, a long-acting moxidectin treatment, short-acting doramectin or control. Six groups of twenty ewes were allocated to individual paddocks, two groups allocated to each treatment, and weekly faecal sampling was performed throughout from the ewes and from six weeks after the start of lambing in the lambs. Treatment group was found to have a significant effect on both ewe FEC (p<0.001) and lamb FEC (p = 0.001) with the group receiving the long-acting anthelmintic having the lowest ewe and lamb FECs. There was no significant effect on the DLWGs of the lambs. Pasture larval counts at the end of the study period were lowest in the long-acting wormer treatment group. The use of long-acting moxidectin may be helpful as part of a parasite control programme by reducing the worm burdens of ewes and their lambs, decreasing the number of anthelmintic treatments required in that year and by reducing pasture contamination for those sheep which will graze the pasture in the next year. However, like all anthelmintics, its use should be judicious to avoid selection for resistance.
