How a Pembrokeshire dairy farm slashed newborn calf mortality rates

WILL and Alex Prichard calve 500 cows in a spring block at Escalwen, near Letterston, and also run two 200-cow autumn calving herds.

That high throughput of calves can present disease challenges – in the three years to 2023, calf mortality from neonatal diarrhoea averaged 9.5%, peaking at 16% in 2022 when the herd was subject to bovine TB movement restrictions.

“Over my entire farming career, one of the most depressing things I have experienced is when calf rearing goes wrong and when mortality and sickness in calves becomes almost insurmountable,’’ said Mr Prichard.

In an attempt to correct weaknesses in their system, in 2023 the Prichards and their calf rearer, Tom Phillips, embarked on a new feeding programme guided by veterinary consultant Ryan Davies.

They invested in two pasteurisers, part funded by the Welsh Government Small Grants – Efficiency scheme, feeding cow transition milk enriched with whole bovine powdered colostrum after calves had received their colostrum feed.

Transition milk is produced by the cow from the second milking after calving, up to the sixth, and contains a higher percentage of milk solids, antibodies, vitamins and minerals than milk produced after this point in the lactation.

It also has elevated levels of growth factors, natural antimicrobial proteins and other bioactive substances.

But the quality of transition milk is highly variable. That, in conjunction with the transfer of passive immunity (TPI) from colostrum dictating a calf’s antibody levels, will make a significant difference to health and performance.

If calves don’t receive sufficient antibodies, they are more likely to die, suffer from diarrhoea or respiratory issues, and require treatment with antibiotics.

Taking blood samples from calves and using IgG as a biomarker to standardise transition milk is one solution and this is what the Prichards did, supported by the Farming Connect ‘Try Out’ Fund, an initiative that funds individuals and groups of farmers and growers to experiment with ideas and bring them to life.

Throughout the calving season, Dr Davies took daily blood samples from newborn calves in their first 24 hours.

The results showed that 21% had an excellent TPI, 7% good, 41% fair and 31% poor.

“This is about average for the UK and good for a dairy block calving herd,’’ said Dr Davies, of Veterinary Technical Consulting Ltd.

The total solids in the pasteurised transition milk were measured with a Brix refractometer and, depending on the reading, it was enriched with a colostrum powder from SCCL to standardise it to a minimum of 12.5% Brix or 14.5% milk solids – instead of powder another option is to add whole milk colostrum.

“If we didn’t reach that threshold we added whole bovine colostrum powder to it to increase the Brix reading,’’ Dr Davies explained.

“The average Brix for the milk at Escalwen was 10.5% so we raised that to 12.5%, but every farm will be different.’’

Other parameters used for the milk were a total bacterial count of under 100,000 colony-forming units (cfu)/ml, a total coliform count of less than 10,000 cfu/ml and no antibiotic residues.

“It is important that calves aren’t fed any antibiotic residues because they inhibit the growth of the normal healthy gut microbiome,’’ said Dr Davies.

The milk was fed to calves up until day 10.

This approach resulted in a significant improvement in calf health and a major reduction in mortalities.

Mortality resulting from neonatal diarrhoea reduced from an average of 9.5% to 3% and antibiotic usage in pre-weaned calves to 16%, from the five-year average of 45%.

Importantly, no highest-priority critically important antibiotics (HP-CIA) were used
pre-weaning in 2024; in 2022 use of these had hit a high of 1.98mg/PCU.

Although feeding transition milk comes with some additional cost, from labour and equipment for its collection through to storage and heating, Mr Prichard said the improvements had completely changed the mood on the farm during the calving period.

“Once you get your head around how important IgGs are, it almost becomes a passion to harvest as much of that IgG as you possibly can and utilise it in your own herd.’’

As well as transition milk feeding, improvements were made to hygiene and cleanliness to reduce the disease challenge.

Pasteurising the milk was a “game changer’’, he added, to reduce disease risks such as Johne’s and bovine TB.

The milk was pasteurised for 60 minutes at 60°C to destroy pathogens including mycoplasma, salmonella, E. coli and listeria.

Pasteurising at higher temperatures or for a longer duration can reduce antibody levels, although studies have shown this is more effective in the destruction of Johne’s and bovine TB organisms which can be detected after heating to 60°C for 60 minutes.

Top tips for feeding transition milk

Adhere to good hygiene practices when collecting and storing prior to feeding
Heat to the correct temperature before feeding
Take the health status of the herd into account to reduce risk of disease transfer, particular if pasteurisation is not used.
In systems that feed calf milk replacer instead of whole milk, the equivalent mass of milk powder should be removed and replaced with colostrum powder to maintain the solids percentage and prevent osmotic diarrhoea.

Badger Trust urges next Welsh Government to keep non-lethal TB policy

Charity says Wales should continue science-led approach as bovine TB cases fall

BADGER Trust has called on the next Welsh Government to maintain a science-led and non-lethal approach to tackling bovine tuberculosis.

The charity says Wales should continue to focus on cattle testing, farm biosecurity and support for farmers, rather than wildlife intervention.

According to Badger Trust, bovine TB cases in Wales had fallen by 13.6% by the end of 2025, without any wildlife culling. It said this compared with a 5% fall in England over the same period.

The charity said 5.3% of cattle herds in Wales were not officially TB-free at the end of 2025, down 0.4 percentage points on the previous year. It said 567 new herd incidents were recorded during the year, alongside a 27% reduction in early cattle slaughter.

Badger Trust said bovine TB remains a serious threat to cattle health, but argued that the best response is a cattle-focused policy, including more frequent and enhanced testing, improved farm hygiene, and non-slaughter options for cattle testing positive.

The charity said: “The premature culling of cattle due to a failed bovine TB test is outdated and unnecessary. Instead, strict segregation is an effective alternative.

“The main focus must be on eliminating the reservoir of bovine TB in the national herd in preparation for cattle vaccination.”

Badger Trust also argued that bovine TB can remain dormant in cattle and in the environment for long periods before being detected, which can lead to mistaken assumptions that infection has entered a closed herd from wildlife.

It said the disease can also be spread through contaminated vehicles, workwear, manure and slurry if proper biosecurity measures are not followed.

The charity added: “Focusing on badgers distracts from the real issue, as DNA testing shows that 94-95% of bovine TB infections are transmitted directly between cattle.

“The only effective way to combat bovine TB is to address it at its source: within the cattle population.”

Badger Trust is urging the next Welsh Government to “hold its nerve” and continue with a science-led, evidence-based, non-lethal policy.

Nigel Palmer, Chief Executive of Badger Trust, said the charity wanted Wales to continue “leading by example” in its approach to tackling the disease.

Badger Trust says it welcomes the end of intensive badger culling licences in England in 2026, but remains opposed to presenting badger vaccination as the main solution to bovine TB. It argues that improved cattle testing and stronger farm biosecurity offer a more effective and humane way forward.

The charity also warned that badgers face a separate threat from changes linked to the Planning and Infrastructure Bill, which it says could weaken protections for badger setts in development areas.

Badger Trust is the leading voice for badgers in England and Wales and works through a network of local badger groups. Its Badgers Belong Here campaign promotes badger protection and public education.

FUW warns food security must be treated as national security

Union says rising fuel and fertiliser costs are putting pressure on farmers and food supply chains

THE FARMERS’ Union of Wales has warned that food security must be treated as a UK-wide priority as global instability continues to drive up costs for farmers.

FUW President Ian Rickman and Deputy President Dai Miles met Defra Minister for Food Security and Rural Affairs Dame Angela Eagle MP in Westminster to discuss the impact of international events on farming, production costs and the resilience of food supplies.

They were also joined by Wales Office Minister Anna McMorrin MP.

The union said the ongoing conflict in the Middle East and Gulf region had added significant pressure to key agricultural inputs and energy costs.

According to the FUW, fertiliser prices, particularly urea and ammonium nitrate, have risen by between 20% and 30% since the escalation of the conflict.

The union is calling for greater transparency around fertiliser stocks and distribution across the UK.

Fuel costs have also risen sharply, with the FUW saying red diesel has effectively doubled in price in some cases. Wider agricultural fuel and energy costs are continuing to rise across the sector, placing further pressure on farm businesses already operating on tight margins.

The union warned that these cost increases are feeding through the entire food supply chain, affecting production, transport, processing and manufacturing, and are likely to contribute further to food price inflation.

The FUW repeated its call for a UK-wide legislative food security metric, which it says should be taken forward by the next Welsh Government in collaboration with the UK Government.

It said food security is a cross-UK issue, affecting all four nations because of the closely integrated nature of agri-food supply chains.

The union also pointed to recent government evidence, including Defra’s 2024 Food Security Report and its 2025 national security assessment on biodiversity loss and ecosystem collapse.

It said these highlighted long-term risks to food production, including climate change, nature decline, animal and plant disease, supply chain disruption and exposure to volatile global markets.

FUW President Ian Rickman said: “We welcomed the opportunity to meet Minister Eagle and Minister McMorrin, and highlight the continued impact of recent global instability on Welsh farmers.

“Food security is national security, and recent global instability has made that clearer than ever.

“Farmers are facing surging cost pressures, particularly from fertilisers and sharply rising fuel costs such as red diesel, which in some cases have doubled.

“These are forces far beyond their control, yet they directly threaten the resilience of our food system.

“We urgently need a coordinated UK-wide approach that recognises the strategic importance of domestic food production and reduces our exposure to volatile international markets.

“With that must come regular and meaningful engagement between Defra and agricultural stakeholders across the UK, including the FUW, particularly on policy areas that remain reserved to the UK Government.”
