Promoting fertility and milk fat production at turnout
SPRING turnout creates many dietary challenges for dairy herds that can result in butterfat depression and fertility issues. However, negative effects can be reduced by balancing rumen function and energy supply, says Dr Richard Kirkland, ruminant nutritionist for Volac Wilmar Feed Ingredients.
“As cows transition from a controlled winter ration to grazed grass, the rumen has to adapt to the differing and more-variable forage source. The diet change alone can cause challenges to rumen function and milk production stability. Additionally, the low fibre and rapid fermentability of early, leafy grass growth can disturb the rumen’s pH balance and cause the grass to pass through the digestive system too quickly, increasing the risk of acidosis,” says Dr Kirkland. “While early grass growth is high in energy, variable spring grazing conditions make it harder for energy supply to be consistently maximised, with a drop in fertility and milk production key risks.”
During early lactation, cows cannot eat enough to meet the high energy demands of milk production, leading to a negative energy balance. This means they rely on body fat stores to support the genetic drive for milk production, resulting in a loss of body condition. Research from the University of Nottingham indicates that for each 0.5-unit loss in condition during this period, conception rates can fall by around 10%.
Cereals are commonly supplemented to increase energy supply, but there is a limit on how much can be used in order to reduce the risk of the rapidly-fermentable starch pushing down rumen pH and with it increasing the risk of acidosis and low milk fat.
“Digestible fibre sources such as soya hulls, citrus and sugarbeet pulp will help balance the starchy energy sources and aid rumen function and milk fat, though offer less of the rumen ‘tickle’ factor than higher-fibre forages. With lower energy concentration than cereals, the greater bulk of forage sources will limit the potential to deliver those vital additional megajoules,” explains Dr Kirkland.
According to him, using a combination of digestible fibre sources and rumen-protected fat supplements in buffer rations will help drive milk production and support fertility in early lactation.
“In contrast to other ingredients, rumen-protected fats are not fermented in the rumen and contain around 2.5-times the energy content of cereals. This makes them an ideal choice to sustain energy supply at grass where conditions can be unpredictable on a daily basis,” says Dr Kirkland.
Selecting the right fat supplement
When selecting a fat supplement to feed in turnout buffer rations, Dr Kirkland says producers need to remember that fat is more than just an energy dense ingredient, with the blend of fatty acids having a primary impact on performance response. Therefore, fatty acid blends should reflect what the farm is trying to achieve and milk contract requirements.
“During the early lactation period, C18:1 (oleic acid) is a key fatty acid, increasing partitioning of energy and nutrients to improve body condition as well as improving development of fertilised eggs. However, given the challenges of early spring grass, products containing higher levels of C16:0 (palmitic acid) can be considered as effective ingredients to increase milk fat production,” explains Dr Kirkland.
To take advantage of the so-called ‘high-C16’ milk fat benefits while protecting fertility, Dr Kirkland recommends feeding a balanced supplement such as Mega-Fat 70. This will provide a higher level of C16:0 than the standard calcium salts but still supplies that important rumen-protected source of C18:1.
“By understanding the impact individual fatty acids have on production response throughout the lactation cycle, rumen-protected fat supplements become multi-purpose and allow producers the opportunity to balance rumen function and energy supply, while also targeting specific milk contract and herd performance goals,” concludes Dr Kirkland.

Cwm Deri Vineyard Martletwy holiday lets plans deferred
CALLS to convert a former vineyard restaurant in rural Pembrokeshire which had been recommended for refusal has been given a breathing space by planners.
In an application recommended for refusal at the December meeting of Pembrokeshire County Council’s planning committee, Barry Cadogan sought permission for a farm diversification and expansion of an existing holiday operation through the conversion of the redundant former Cwm Deri vineyard production base and restaurant to three holiday lets at Oaklea, Martletwy.
It was recommended for refusal on the grounds of the open countryside location being contrary to planning policy and there was no evidence submitted that the application would not increase foul flows and that nutrient neutrality in the Pembrokeshire Marine SAC would be achieved within this catchment.
An officer report said that, while the scheme was suggested as a form of farm diversification, no detail had been provided in the form of a business case.
Speaking at the meeting, agent Andrew Vaughan-Harries of Hayston Developments & Planning Ltd, after the committee had enjoyed a seasonal break for mince pies, said of the recommendation for refusal: “I’m a bit grumpy over this one; the client has done everything right, he has talked with the authority and it’s not in retrospect but has had a negative report from your officers.”

He said the former Cwm Deri vineyard had been a very successful business, with a shop and a restaurant catering for ‘100 covers’ before it closed two three years ago when the original owner relocated to Carmarthenshire.
He said Mr Cadogan then bought the site, farming over 36 acres and running a small campsite of 20 spaces, but didn’t wish to run a café or a wine shop; arguing the “beautiful kitchen” and facilities would easily convert to holiday let use.
He said a “common sense approach” showed a septic tank that could cope with a restaurant of “100 covers” could cope with three holiday lets, describing the nitrates issue as “a red herring”.
He suggested a deferral for further information to be provided by the applicant, adding: “This is a big, missed opportunity if we just kick this out today, there’s a building sitting there not creating any jobs.”
On the ‘open countryside’ argument, he said that while many viewed Martletwy as “a little bit in the sticks” there was already permission for the campsite, and the restaurant, and the Bluestone holiday park and the Wild Lakes water park were roughly a mile or so away.
He said converting the former restaurant would “be an asset to bring it over to tourism,” adding: “We don’t all want to stay in Tenby or the Ty Hotel in Milford Haven.”
While Cllr Nick Neuman felt the nutrients issue could be overcome, Cllr Michael Williams warned the application was “clearly outside policy,” recommending it be refused.
A counter-proposal, by Cllr Tony Wilcox, called for a site visit before any decision was made, the application returning to a future committee; members voting seven to three in favour of that.

Farmers Union of Wales Warns: Labour’s 5G Expansion Risks Rural Blackspots
FUW Joins Landowners in Urgent Call to Pause Controversial Telecoms Reforms
THE FUW (Farmers’ Union of Wales) has warned that rural communities face worsening mobile blackspots and farmers risk losing essential income if the Labour Government expands a telecoms policy blamed for stalling Britain’s 5G rollout.
In a letter to Digital Economy Minister Liz Lloyd, the FUW aligns with landowners, investors, and property experts demanding a halt to Part 2 of the Product Security and Telecommunications Infrastructure (PSTI) Act 2022. Extending the 2017 Electronic Communications Code (ECC) would “entrench failure,” the group argues, sparking more stalled renewals, site losses, and legal battles just as Wales needs swifter rural connectivity.
The 2017 reforms empowered operators to cut mast rents—often by 90%—from hosts like farmers, councils, and NHS trusts. Far from boosting rollout, they’ve ignited over 1,000 tribunal cases since 2017, versus 33 in the prior three decades. Rural goodwill has eroded, with hosts now eyeing exits.
“Every lost mast isolates households, schools, and businesses,” the FUW states. “No public subsidy can fix this systemic damage.”
A survey of 559 hosts (via NFU, CLA, BPF) shows:
- 35% considering full withdrawal.
- 70% of expired lease holders facing operator legal threats.
Landowner Ted Hobbs in New Tredegar shares the pain: “My 1995 Vodafone lease was £3,500 yearly, renewed in 2010 at the same rate. It expired May 2025—now they demand a slash, backed by the Code. This is confiscation, not partnership.”
Labour’s push forward—despite earlier opposition and a critical consultation—ignores these red flags.
FUW President Ian Rickman adds: “Farmers hosted masts in good faith for rural connectivity. Punishing them with rent cuts sabotages Wales. Halt this now, restore trust, and incentivise real progress.”
The coalition urges ministers to reopen dialogue before deepening rural divides. Wales can’t afford more policy missteps.

Large new development at one of Pembrokeshire’s biggest dairy farms approved
PLANS for a heifer accommodation building and associated works at one of Pembrokeshire’s largest dairy farms, with a milking herd of 2,000 cows, have been given the go-ahead.
In an application recommended for approval at the December 2 meeting of Pembrokeshire County Council’s planning committee, Hugh James of Langdon Mill Farms Ltd sought permission for a 160-metre-long heifer accommodation building, a slurry separation/dewatering building and associated yard areas at 1,215-hectare Langdon Mill Farm, near Jeffreyston, Kilgetty.
A supporting statement through agent Reading Agricultural Consultants said: “The holding currently has a milking herd of approximately 2,000 cows, which are housed indoors for the majority of the year, with dry cows and heifers grazed outdoors when weather and soil conditions permit.
“There has been significant investment in buildings and infrastructure at the farm over the last decade in respect of cattle accommodation, slurry storage, milking facilities, Anaerobic Digestion (AD) plant, feed storage. Recently a calf and weaned calf accommodation buildings were approved by Pembrokeshire County Council with construction almost complete.
“The unit is efficient, achieving yields of more than 10,000 litres/cow/year, with cows being milked three times/day in the 60-point rotary parlour. Langdon Mill Farm currently directly employs 21 full-time, and three part-time staff. Of these, four live on site in the two dwellings opposite the farm, with the remaining staff living in the locality.”

It added: “Although the unit has previously purchased heifers to aid expansion, the farm now breeds most of its own replacements to improve genetics and to minimise the ongoing threat of bovine tuberculosis (bTB).
“Following the completion of the calf and weaned calf accommodation buildings, the farm will be rearing all of the cattle under seven months at Langdon Mill Farm, before being transported off site to be reared at three farms in the local area. At 22-months the in-calf heifers are brought back to the maternity building to calve and then are introduced into the milking herd.”
It said the proposed building would be used by heifers between the ages of 7-22 months, the siting “directly influenced by the adjacent calf and weaned calf buildings, with livestock being moved from one building to the next as they get older”.
Approval was moved by Cllr Brian Hall, seconded by Cllr Danny Young, with Cllr John T Davies also stating his support.
“It’s common sense; the fact we approved a calf-rearing shed, it follows on you need a heifer rearing shed,” he said.
Cllr Davies later said the scheme would also support biodiversity, and, with a decline in milk prices, supporting the large-scale farm was about “safety in numbers”.
Chair Cllr Mark Carter said it was “a pleasure to be supporting the farming industry”.
Members unanimously supported the recommendation of approval.
