Targeted worm dosing helps lamb producer cut drench use
THE USE of wormer in a Welsh sheep flock has dropped dramatically thanks to Targeted Selective Treatment (TST) – an approach that identifies which lambs actually need treatment, avoiding unnecessary blanket dosing.

TST uses individual indicators such as growth rate and takes into account the flock’s faecal egg count (FEC). Father and son Glyn and Chris Davies, who run 650 crossbred ewes at Awel y Grug, Cefn Coch, Montgomeryshire, have been trialling the method as part of a Farming Connect Our Farms project – with impressive results.
In July, after a spell of hot weather and rain, the flock recorded an FEC of 446 eggs per gram. Normally, this would have triggered worming of all lambs. But by following the TST protocol, less than half actually needed treatment.
According to Owain Pugh, Farming Connect red meat sector officer, the approach has resulted in 855 fewer doses being administered over two treatment cycles (June and July) and a saving of almost £60 in drench.
“It’s a solid financial saving,” he said, “but more importantly it slows the development of anthelmintic resistance and helps protect dung beetles.”
The Davies family’s journey towards more responsible wormer use began in 2018. An early reduction test revealed resistance to white drench (1-BZ) – likely caused by over-reliance on a single drench group. Since then, they have rotated between yellow (2-LV) and clear (3-ML) drenches, using orange (4-AD) and purple (5-SI) strategically, and only applying white drench for Nematodirus when strongyle worm burdens are low.
They also invested in an auto-calibrated dosing applicator connected to weigh scales, allowing each lamb to receive a precise dose for its weight. Technical challenges were overcome with support from livestock advisor Matt Blyth, facilitated by Farming Connect, and by investing in weighing equipment compatible with the Cotter Agri SmartWorm app used for TST.
Fiona Kenyon, Principal Research Scientist at the Moredun Research Institute, analysed the FEC samples to identify worm species present. This data, she explained, is vital in understanding resistance patterns and optimising the timing of specific drug classes.
“TST can save time, labour and cut drench use – all of which lower input costs. It also slows the development of wormer resistance, helping preserve the effectiveness of our limited treatments,” she said.
For the Davies family, the change has been transformative. Dosing sessions are now much faster – one recent session took just 30 minutes, three times quicker than treating the whole group – and costs are down without compromising lamb productivity.
Chris Davies says that accurately weighing each lamb and dosing accordingly “makes sense in every way.” Visual weight estimates, he now realises, are too unreliable.
“With TST we’re neither under-dosing nor over-dosing,” he said. “And by monitoring weights closely, we can hold back lambs for a few extra weeks to achieve higher sale weights and prices.”
He admits setting up the system was challenging and can see why some farmers might give up at that stage. “But once it’s in place, you won’t look back.”
Alongside other Our Farms projects such as growing clover for finishing lambs and rotational grazing, TST has strengthened the business.
“All the changes we’ve made in the last two years have put us in a much stronger position,” Chris said.

Plans to rebuild arson hit building at farm with one of largest sheep flocks in Wales
A CALL to rebuild a fire-damaged Pembrokeshire farm building, as a family home to help manage one of the largest sheep flocks in Wales, has been submitted to the national park.
In the application to Pembrokeshire Coast National Park, D B Davies and Sons through agent Harries Planning Design Management, with a supporting statement by Reading Agricultural Consultants Ltd, seek permission to renovate an existing fire-damaged dwelling, together with the conversion and extension of outbuildings to form an agricultural worker’s dwelling at Mynydd Du, Rosebush.
The supporting statement through Reading Agricultural Consultants Ltd says Mynydd Du is part of a wider holding which includes Eisteddfa Fawr and land around the village of Brynberian, the farms approximately six km apart, with land under control of the applicant amounting to some 1,500 acres, with a further 3,000 acres of Preseli mountain common land also used; the land accommodating a 5,000-ewe flock with 10 suckler cows and followers.
It says DB Davies & Sons Unlimited, has five partners: the two Davies brothers, Berian and Ken; their wives; and Berian’s son, Dyfed.
Berian and Ken are in their late 70s, with most of the heavy work on the farm is undertaken by Dyfed.
Dyfed and his wife Megan are first language Welsh speakers, living some 10 km away in Nevern, while Berian and Ken, and their wives, live at Eisteddfa Fawr, Brynberian.
The dwelling at Mynydd Du, where most sheep are now wintered, is structurally sound and repairable but has been unoccupied since 1990, and was subject to arson circa 2013, the statement says.
It says Dyfed works full-time on the farm, alone with increasing frequency as the older business members are above retirement age, working “long hours out of necessity to undertake all the work associated with one of the largest flocks of sheep in Wales”.
“His working hours are extended further due to the fact that he lives remote (6kms) from the main block of land at Tyllosg, where Mynydd Du is situated in the centre of the farm. Travelling back and forth several times each day during lambing and other times during poor weather, to check on flock welfare is an arduous task and can be dangerous, particularly if driving when tired during inclement conditions.”
The statement adds: “The application seeks permission to repair the fire damaged dwelling at Mynydd Du and bring it back to serve a useful purpose to enable Dyfed to closely monitor the ewes, not only at lambing, but throughout the year when the flock is grazing on the adjacent common land.
“It will also enable Dyfed to be with his partner and young child on a more regular basis than simply at the end of a long day when he is away from their current home, tending the sheep at Mynydd Du.”
The application will be considered by park planners at a later date.

Wales sees progress in bovine TB fight as debate over badger role continues
New figures show decline in herd incidents, but disagreement remains over wildlife controls
WALES is making steady progress in tackling bovine tuberculosis (bTB), according to the Welsh Government, but a long-running debate over the role of badgers in spreading the disease continues to divide opinion.
In a written statement issued this week, Deputy First Minister and Cabinet Secretary for Climate Change and Rural Affairs, HUW IRRANCA-DAVIES, outlined what he described as “clear progress” in Wales’s eradication programme.
Latest figures show a sustained long-term decrease in new TB herd incidents, which ministers say reflects the success of a science-led, cattle-focused strategy. The approach has prioritised enhanced testing, stricter movement controls, and improved biosecurity on farms.
The Welsh Government says more sensitive testing methods are helping to identify infection earlier, while efforts are also being made to reduce the number of cattle slaughtered unnecessarily.
However, the issue of whether wildlife—particularly badgers—plays a significant role in spreading the disease remains contentious.
Farmers and government under pressure
Bovine TB continues to have a major economic and emotional impact on Welsh farming communities, particularly in rural areas of Pembrokeshire, Carmarthenshire and Ceredigion.
Farmers’ unions have long argued that wildlife reservoirs, including badgers, contribute to the persistence of the disease, and have called for stronger intervention measures.
In England, controversial badger culling programmes have been rolled out over the past decade, with UK Government figures suggesting significant reductions in TB rates in some areas.
But those claims remain disputed, with critics arguing that the evidence is far from clear-cut.
Badger Trust backs Welsh approach
Responding to the Welsh Government’s latest statement, the Badger Trust welcomed the direction of policy in Wales and urged ministers to maintain a focus on cattle-based controls.
The charity said the latest statistics demonstrated that Wales’s approach was delivering “real results” and represented a clear improvement on policy seen elsewhere.
Chief Executive NIGEL PALMER said: “The latest TB statistics show sustained long-term decreases in new TB herd incidents, demonstrating that Wales’s science-led, cattle-focused approach is delivering real results.”
The Trust also questioned the effectiveness of culling, arguing that reductions in England cannot be attributed solely to killing badgers.
It said: “The analysis behind this figure cannot separate the effects of culling from other measures such as enhanced cattle testing, stricter movement controls, and improved biosecurity.”
The organisation maintains that bovine TB is primarily a cattle disease, with most transmission occurring between cattle rather than from wildlife.
Scientific disagreement remains
The role of badgers in spreading bTB has been the subject of decades of scientific study, with no universal consensus.
Some studies have suggested that badgers can act as a reservoir for the disease, potentially infecting cattle through environmental contamination.
Others, including research cited by animal welfare groups, argue that the impact of badgers on overall transmission rates is limited compared to cattle-to-cattle spread.
The Welsh Government’s own Technical Advisory Group has previously stated that a combination of measures may be needed, including consideration of wildlife alongside cattle controls.
However, Wales has so far resisted introducing widespread badger culling, instead focusing on vaccination trials and tighter cattle measures.
Calls for clarity and consistency
The Badger Trust also raised concerns about international standards, arguing that requirements for Officially TB Free status focus primarily on bovine species rather than wildlife.
It warned that policies targeting badgers risk diverting attention and resources away from more effective cattle-based interventions.
At the same time, farming representatives continue to press for stronger action, arguing that without addressing all potential sources of infection, eradication efforts could stall.
A long road ahead
While the latest figures suggest progress, the Welsh Government has acknowledged that completely eradicating bovine TB remains a long-term challenge.
For now, Wales appears set to continue its cautious, evidence-led approach—balancing animal health, farming livelihoods, and wildlife protection.
But with pressure mounting from both sides of the debate, the question of how far to go in tackling the disease is unlikely to be settled any time soon.

£3 million secured to continue Welsh sheep genetics programme
THE WELSH GOVERNMENT has confirmed £3 million in funding over the next three financial years to continue the Welsh Sheep Genetics Programme (WSGP), helping Welsh sheep farmers improve efficiency, productivity and environmental performance.
From April 2026, Hybu Cig Cymru – Meat Promotion Wales (HCC) will lead Phase 2 of the programme, marking a significant next step in supporting farmers to make smarter, evidence-based breeding decisions.
The new phase will provide transition support for existing participants while also opening the programme to new flocks. Farmers will receive practical, technical and financial support to make use of Genomic Estimated Breeding Values, advanced genetic tools designed to help them make better-informed decisions at farm level. The data collected will also strengthen industry benchmarking and support longer-term business planning.
Phase 2 will also include the development of robust key performance indicators, tailored farm-level action plans, and an ambitious portfolio of research projects aimed at driving innovation across the sector.
The programme’s objectives are closely aligned with the Sustainable Farming Scheme, which launched on January 1, 2026, as well as HCC’s Vision 2030, reflecting a shared commitment to a productive, sustainable and competitive Welsh red meat industry.
Phase 1 of the WSGP, delivered by Farming Connect, comes to an end on March 31, 2026. Since launching in 2023, the programme has achieved significant progress, including introducing genomics into the sheep sector for the first time anywhere in the world.
It has also generated 70,000 genotypes across Tier 1 and Tier 2 flocks on the AHDB-Signet database since 2023, the highest number recorded there, while developing two major research strands focused on breeding for worm resistance and reduced methane emissions.
The programme has worked in close partnership with leading specialists, including Innovis and AHDB-Signet, and has delivered measurable genetic gains and improvements in key performance traits across participating flocks.
The investment underlines the Welsh Government’s commitment to reducing greenhouse gas emissions while supporting the production of high-quality, sustainable PGI Welsh Lamb.
Deputy First Minister for Climate Change and Rural Affairs, Huw Irranca-Davies, said: “This funding demonstrates our commitment to supporting farmers to build profitable, resilient businesses while delivering on our climate ambitions. The Welsh Sheep Genetics Programme shows what is possible when cutting-edge science meets the proud tradition of Welsh livestock farming. By helping farmers breed healthier, more productive flocks with a lower environmental footprint, we are strengthening food security and safeguarding our rural economy for the long term.”
José Peralta, Chief Executive of Hybu Cig Cymru, said: “The progress achieved to date reflects the commitment of farmers across Wales, the work of the Farming Connect team, and the continued financial support of the Welsh Government. Together, these provide a strong platform for the next phase.
“This next step directly supports a core priority in our new strategic plan: to develop and lead the implementation of initiatives that improve economic and environmental sustainability. We look forward to working closely with farmers to ensure they have the tools, insights and support needed to thrive in the years ahead.”
