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.

Check ewes at weaning to protect next season’s lamb crop
PEMBROKESHIRE sheep farmers are being urged to use weaning as a key opportunity to check ewe condition and deal with any problems before tupping.
With many local flocks now moving towards weaning, farmers are being advised to assess body condition score, as well as checking teeth, feet and udders, while there is still time to improve nutrition ahead of the breeding season.
Dr Alison Bond, Technical Services Manager at Rumenco, said close monitoring at this stage can help avoid major changes in ewe condition and improve overall flock productivity.
She said weaning at around 12 weeks was a good target, when lambs should usually be between 25kg and 30kg and taking very little milk from the ewe.

“There will of course be a focus on the lambs’ readiness for market at this stage, but it is equally important to put a hand across the ewes to assess their condition,” she said.
For lowland flocks, ewes with a body condition score below 2.5 at weaning should be given priority, as they may struggle to reach the target score of around 3.5 by tupping.
Those poorer condition ewes should be grouped separately, moved onto the best available grazing and given appropriate supplementary feeding where needed.
Dr Bond said waiting until closer to tupping could be less effective and may affect performance.
She added that ewes in good condition at tupping are more likely to scan with more lambs, produce healthier lambs after birth, and rear heavier lambs by eight weeks of age.
“It affects the whole production cycle, and not just one element,” she said.
The advice will be particularly relevant to farms across Pembrokeshire, Carmarthenshire and Ceredigion, where sheep remain a major part of the rural economy and where grass quality can vary sharply depending on weather, soil type and stocking pressure.
Dr Bond said the aim should be to keep ewes between body condition score 2.5 and 3.5 throughout the cycle, avoiding big dips and peaks.
Routine checks at weaning, she said, give farmers the best chance of correcting problems before the tups go in two to three months later.

Reform calls for urgent review of farming scheme
LOW UPTAKE HAS RAISED FRESH QUESTIONS OVER THE FUTURE OF SUPPORT FOR WELSH FARMERS
REFORM WALES has called for an urgent review of the Sustainable Farming Scheme after figures showed only around half of eligible farmers have signed up.
The party said the lower-than-expected uptake showed that serious concerns remained within the farming community over the complexity of the scheme, compliance rules and uncertainty about how it will operate in the long term.
Laura Anne Jones MS, Reform Wales’ Shadow Cabinet Minister for Food, Farming and Rural Affairs, raised the issue during questions to the Welsh Government.
She said: “The figures released by the Welsh Government today confirm what many farmers have been saying for some time: the Sustainable Farming Scheme is too complex, too restrictive and too bureaucratic.
“Farmers need certainty and security, not endless paperwork and rigid requirements that fail to reflect the realities of farming in Wales.
“Reform Wales believes the scheme should be reviewed as a matter of urgency, with a greater focus on flexibility, common sense and practical outcomes.
“Welsh farmers deserve a scheme that works with them, not against them.”
The Sustainable Farming Scheme is due to replace previous systems of agricultural support in Wales and has been one of the most contentious issues facing the rural sector.
Farming unions and campaigners have repeatedly warned that any new system must be practical for family farms and must not add unnecessary red tape at a time when many businesses are already under pressure from rising costs, bovine TB and market uncertainty.
Reform Wales said the Welsh Government must now explain how it intends to respond to the level of take-up and whether changes will be made before the scheme is fully rolled out.

Holiday accommodation conversion of historic farm buildings approved
PLANS to convert historic farm buildings near north Pembrokeshire’s Whitesands beach for use as holiday accommodation have been given the go-ahead, but their use doesn’t have to be restricted to just that purpose.
In an application to Pembrokeshire Coast National Park, Matthew James of James Properties, through agent Harries Planning Design Management sought permission for the conversion of two derelict barns to two self-catering holiday accommodation units at Porthmawr Ganol, Whitesands, St Davids.
An officer report said: “The farmstead occupies a prominent position within a landscape characterised by open agricultural fields enclosed predominantly by traditional dry-stone walls, exposed coastal pasture and areas of heathland associated with Carn Llidi.”
It added: “The site lies within the Porthmawr Historic Landscape Character Area, an area recognised for its historic pattern of dispersed settlement, traditional farmsteads, dry-stone wall field boundaries and evidence of medieval and post-medieval agricultural activity.
“The retention and reuse of the existing buildings therefore has the potential to preserve an important element of the area’s historic landscape character whilst securing a viable long-term future for structures that would otherwise continue to deteriorate.”
It said that insufficient evidence had initially been submitted to demonstrate that the buildings were unsuitable for permanent residential conversion and only for self-catering accommodation and therefore an affordable housing contribution should be secured.
Policy would lead to a contribution of £36,400, the report said, but a financial viability assessment by the applicant “demonstrated that the development would not be viable if required to provide the full policy contribution,” the maximum contribution capable of being supported whilst maintaining viability was £12,641.
This reduced figure was accepted, the officer report saying: “Whilst this represents a reduced contribution when compared with the full policy requirement, the submitted viability evidence demonstrates that the development could not reasonably support the full contribution whilst remaining deliverable.
“In these circumstances, securing a reduced contribution is considered preferable to losing the opportunity to secure the restoration and beneficial reuse of the historic buildings.”
It stated that, with the affordable contribution, the scheme would not be limited to self-catering development only.
The application was conditionally approved by Park planners.
