Spotlight on ammonia reduction strategies for Welsh poultry producers

Published

A WELSH study has refocused attention on strategies for reducing ammonia emissions in the poultry sector, with farmers urged to adopt measures including good ventilation and litter and manure management protocols to lower levels.

A three-year European Innovation Partnership (EIP) Wales trial on two broiler farms looked specifically at the role additives may have in reducing emissions by improving gut health and flock performance.

The study produced no evidence that these were effective for this purpose – similar levels of ammonia were recorded in the control and treatment houses.

But project manager Jason Gittins, technical director for livestock at ADAS, says there are a number of other measures that farmers can put in place to tackle emissions.

Ammonia is a component of urea, which is excreted in poultry faeces; when that manure is exposed to air and to moisture, the gas is released.

Agriculture is a major source of ammonia, accounting for 87% of UK emissions in 2019; of this, 14% came from poultry production.

“Ammonia gas is a harmful gas to both poultry and poultry workers and excessive nitrogen deposition resulting from ammonia emissions also damages the environment,’’ warns Mr Gittins.

Here, he gives his advice on how poultry farmers can reduce those emissions.

Ventilation

Poorly ventilated sheds will result in wet litter, which allows more ammonia to be released into the air. The use of effective ventilation to optimise the in-house environment, and preventing condensation can increase litter dry matter content and so reduce ammonia emissions.

Indirect heating systems heat the shed without the additional carbon dioxide and water vapour produced by direct gas heating systems, Mr Gittins explains.

“As a result, litter condition is often drier, which makes conditions less favourable for the production of ammonia,’’ he points out.

Ammonia scrubbing systems

These systems typically pass exhaust air from the house through a liquid to capture the ammonia; the air released to the atmosphere then has a lower ammonia content. Mr Gittins says reports have indicated that reductions in ammonia emissions of around 80% are possible using scrubbing systems, but the capital and operating costs are high.

Correct diet formulation

Diets should be formulated based on amino acid requirements, rather than crude protein, Mr Gittins advises.

“Diet formulation should change throughout the flock cycle to ensure that the nutrient supply is closely matched to the birds’ ammonia acid and other nutrient requirements.’’

Improvements in feed utilisation and feed conversion ratio (FCR) provide both environmental and financial benefits.

Correct removal and storage of soiled bedding

Manures should be contained in covered stores on impermeable surfaces. If field heaps are used, the surface area should be as small as possible: ‘A’ shaped, as this will reduce emissions, says Mr Gittins.

“A key issue is that wet poultry manure and litter can lead to higher emissions of ammonia and so the priority is to keep them as dry as possible, both during housing and afterwards.

“This can also increase its value per tonne as a fertiliser and reduce haulage costs and odour risks.’’

Manure applications should follow normal good practice, he adds.

“This should include avoiding spreading during frost, snow and heavy rain and taking account of soil conditions at the time.

“For liquid organic manures, precision spreading methods are preferable to splash-plate systems.’’

In free-range egg production, the move to multi-tier systems, rather than single-tier, is consistent with reducing ammonia, because of belt clean-out and frequent manure removal.

Preventing puddling around drinkers

Keeping litter dry is key to reducing ammonia levels. Drinkers should be managed to prevent spillages – any leaks need to be identified and quickly resolved.

“Nipple drinker systems should be adopted, as these allow better management of water intake and reduce water wastage,’’ Mr Gittins recommends.

High bird health

Keeping the health status of birds high will help to maintain litter in a drier condition.

“Birds challenged with disease and in poor health often produce wetter manure, which can result in higher ammonia emissions,’’ says Mr Gittins.

EIP Wales, which is delivered by Menter a Busnes, has received funding through the Welsh Government Rural Communities – Rural Development Programme 2014-2020, which is funded by the European Agricultural Fund for Rural Development and the Welsh Government.

AN OFFICIAL special farming role for Pembrokeshire’s deputy leader is to be established following a call made to full council, the first time the council has had such a role for a senior member.

In a question to council leader Cllr Jon Harvey, heard at the December meeting of Pembrokeshire County Council’s full council meeting, Conservative group leader Cllr Di Clements asked: “With the recent changes in the budget from the UK Labour Government on Inheritance Tax and Agricultural Property Relief, many Pembrokeshire farmers are feeling concerned for the future of their family farms, many in Pembrokeshire which have been in the same family for generations.

“I have always found it disappointing that in all the years I have been a councillor, and the major contribution farming has to this county’s economic, cultural and environmental well-being, there has never been a Cabinet Member’s title with rural affairs or farming, or agriculture within it.

“To show that this council recognises the importance of agriculture, and the hundreds of millions of pounds generated by farming, will the Leader consider including it in one of the titles of his Cabinet Members’ portfolio?”

Responding, Cllr Harvey said: “I full share your perspective; it’s true this council has never had a Cabinet member with this role; however I can reconsider, I regard all aspects of rural life as vitally important.”

He told members farming and rural affairs came under the portfolio of the deputy leader [Cllr Paul Miller], adding: “we’re all aware of the changing aspects of rural life at the moment, we do have a rural affairs champion in Cllr Steve Alderman, but I’ve had a conversation with the deputy leader and agreed to review this title to reflect the importance of the role and will happily make an announcement in the next few days.”

Cllr Clements responded: “These words say a lot, it shows this council recognises the importance of the most constant and probably most important business in the county.”

Call for Pembrokeshire to oppose farming inheritance tax withdrawn

A CALL on Pembrokeshire County Council to oppose government changes to inheritance tax affecting family farms has been withdrawn, but its proposer hopes his motion will return to a future meeting.

At the Budget, Chancellor Rachel Reeves announced farmers would have to pay inheritance tax on agricultural property and land worth more than £1 million at a rate of 20 per cent, with a £3m threshold for couples passing on their farms.

This compares to a 40 per cent rate on other estates.

A Notice of Motion by Councillor Aled Thomas, ‘relating to Protecting British Family Farms and Preserving Rural Communities’ was to be heard at the December 12 meeting of Pembrokeshire County Council’s full council meeting.

Cllr Thomas, who stood as a Conservative candidate for Ceredigion-Preseli in the 2024 general election, asked that: “Pembrokeshire County Council notes its concern to the proposed changes to inheritance tax announced by the Labour Government in the recent Autumn budget, which would scrap Agricultural Property Relief (APR).

“APR has been instrumental in allowing British family farms to remain intact across generations, supporting food security, sustaining rural communities, and aiding environmental stewardship. This tax is estimated to impact over 70,000 family farms, leaving the average farming family with a tax bill of at least £240,000, which will force many to sell portions of their land or close entirely, paving the way for corporate ownership over family ownership.”

It called on the council to resolve to “oppose the Labour Government’s changes to inheritance tax affecting family farms,” to “advocate for the exemption of family farms to preserve the UK’s food security, rural communities, environmental initiatives,” and to “commit to maintaining its county council farms portfolio, particularly to encourage younger and new generations of farmers into the industry”.

It finished: “This council urges all councillors to stand with Britain’s family farms, to support our rural communities, and to protect the environment by formally rejecting this proposed ‘family farm tax’.”

At the December 12 meeting Presiding Member Cllr Simon Hancock informed members the notice had been withdrawn from the meeting.

Speaking after the announcement, Cllr Thomas, himself a farmer, said: “There was a dispute whether I should have been allowed to submit it as I am a farmer, so I took advice from the monitoring officer that I should withdraw it until I can get a dispensation from the standards committee to speak on the matter.”

He said he hoped to get the motion resubmitted to be heard at the next council meeting.

THE ROYAL WELSH WINTER FAIR TASTE AWARDS, showcasing the finest native lamb breeds of Wales in a celebration of sustainability, flavour and culinary excellence, were hosted by the Royal Welsh Agricultural Society (RWAS).

The awards, held in collaboration with Cambrian Training Company, the Culinary Association of Wales and the National Culinary Team Wales, spotlighted the exceptional quality of Welsh Lamb and its unique characteristics.

The competition aimed to promote native Welsh Lamb breeds and emphasise their distinct flavours, encouraging chefs, businesses and consumers to consider Welsh Lamb a premium product.

The RWAS says the competition provides a vital platform to showcase the exceptional flavours of native Welsh Lamb breeds while promoting sustainable farming practices.

These lambs are grass-fed, raised in Wales and come with full traceability from farm to fork. The initiative aims to highlight the story behind the meat and the dedicated efforts of farmers in preserving these breeds.

Societies representing seven native Welsh Lamb breeds participated in the competition, held at the Cambrian Training Company building on the Royal Welsh Showground at Llanelwedd.

Each breed’s lamb was expertly cooked by chefs and presented to a distinguished panel of judges, including Dilwyn Evans, a vet featured on TV series ‘Clarkson’s Farm’, Steven Owen, Castell Howell development chef, Neil Fenn, Professor Rhian Goodfellow, OBE and Arwyn Watkins, OBE, executive chair of Cambrian Training Group.

The breeds showcased included Badger Face Welsh Mountain (Torddu and Torwen), Balwen Welsh Mountain, Black Welsh Mountain, Clun Forest, South Wales Mountain, Llanwenog and Pedigree Welsh Mountain.

Each lamb had been bred, born and reared in Wales, ensuring sustainable and traceable farming practices.

The awards highlighted the diversity among native Welsh Lamb breeds, from the Torddu and Torwen’s hardy nature to the Llanwenog’s docile temperament and premium meat quality.

Farmers and breed societies demonstrated the unique traits of their lambs, such as flavour, sustainability and adaptability to diverse farming environments.

Arthur Davies (South Wales Mountain) and I. T. Davies & Son (Clun Forest) were declared joint winners of the Royal Welsh Winter Fair Taste Awards. Both breeds impressed the judges with their remarkable flavour, tenderness and quality, showcasing the very best of Welsh Lamb.

The event emphasised the importance of promoting the culinary excellence of Welsh Lamb alongside its visual appeal in show rings.

Guest judge, Dilwyn Evans said: “It has been an absolute honour to judge the Royal Welsh Winter Fair Taste Awards and experience first-hand the superior taste of native Welsh Lamb.

“This exceptional meat not only embodies the rich heritage and dedication of Welsh farming but also highlights the importance of preserving these unique breeds and the sustainable practices behind them.”

The RWAS thanked the judges and Cambrian Training Group for their continued support, helping ensure the lambs were cooked to perfection for the competition.

With the awards, Wales has cemented its position as a leader in premium lamb production, bringing the exceptional flavours of its native breeds to the forefront of the culinary world.
