Reducing ammonia emissions from broiler chicken production
Reducing ammonia emissions from broiler chicken production
Objectives
The use of ammonia-reducing additives, either applied directly to the litter or supplied to the birds via the drinking water, offers an additional means of further reducing ammonia production. Two established commercial broiler producers, with modern buildings and many years’ experience of producing poultry for the UK market, are involved in this one year project investigating how these additives can reduce their ammonia emissions.
Objectives
Mae defnyddio ychwanegion sy’n lleihau amonia, naill ai drwy eu hychwanegu’n uniongyrchol at y sbwriel neu ei gyflenwi i’r adar drwy’r dŵr yfed, yn cynnig dull ychwanegol o leihau cynhyrchiant amonia ymhellach. Mae dau gynhyrchydd brwyliaid masnachol profiadol, gydag adeiladau modern a blynyddoedd o brofiad o gynhyrchu dofednod ar gyfer marchnad y DU, yn cymryd rhan yn y prosiect blwyddyn hwn i edrych sut y gall yr ychwanegion hyn leihau eu hallyriadau amonia.
Activities
1) Three different ammonia reducing additives will be tested
2) Each of the three additives will be used for one production cycle (2 months) on each farm
The following variables will be monitored and recorded for each treatment:
1) Ammonia levels within the houses
2) In house temperature
3) Foot pad condition, hock and gait scoring
4) Feather condition
5) Litter condition
6) Mean bird liveweight
7) Flock mortality
8) Feed intake
Activities
1) Bydd tri gwahanol ychwanegyn sy’n lleihau amonia yn cael eu profi
2) Bydd pob un ohonynt yn cael eu defnyddio ar gyfer un gylchred gynhyrchu (2 fis) ar y ddwy fferm
Bydd y ffactorau amrywiol canlynol yn cael eu monitro a’u cofnodi ar gyfer pob triniaeth:
1) Lefelau amonia yn y siediau
2) Tymheredd o fewn y siediau
3) Cyflwr gwaelod y traed, yr egwyd a sgorio symudiad
4) Cyflwr y plu
5) Cyflwr y sbwriel
6) Cymedr pwysau byw’r adar
7) Cyfradd marwoldeb yr haid
8) Cymeriant bwyd

1 Practice Abstracts
Broiler production has been a growth area in Welsh agriculture in recent years. The growing demand for chicken has provided viable diversification opportunities for a number of Welsh farmers. An inevitable consequence of any form of poultry farming is the production of ammonia, through the natural breakdown of urates within poultry manure. Ammonia emissions from poultry production can have a number of significant impacts on the environment, bird welfare, and broiler economics.
Existing legislation is in place to reduce ammonia emissions from poultry farms. High levels of ammonia emissions are cited as one of the main reasons for permits being refused or for planned expansion being prohibited. Modern housing with better ventilation and heating along with improved litter has reduced ammonia emissions, however further improvements may be possible by using additives.
The use of ammonia-reducing additives, either applied directly to the litter or supplied to the birds via the drinking water, offers an additional means of further reducing ammonia production. Two established commercial broiler producers, with modern buildings and many years’ experience of producing poultry for the UK market, are involved in this one year project investigating how these additives can reduce their ammonia emissions.
Mae cynhyrchu brwyliaid wedi bod yn sector sy’n tyfu o fewn amaethyddiaeth yng Nghymru dros y blynyddoedd diwethaf. Mae’r galw cynyddol am gywion ieir wedi cynnig cyfleoedd ymarferol ar gyfer arallgyfeirio i nifer o ffermwyr yng Nghymru. Un o oblygiadau annatod unrhyw fath o ffermio dofednod yw cynhyrchiant amonia, wrth i’r wradau ddadelfennu’n naturiol o fewn tail dofednod. Gall allyriadau amonia o ganlyniad i gynhyrchu dofednod arwain at nifer o effeithiau sylweddol ar yr amgylchedd, lles adar a ffactorau economaidd yn ymwneud â chynhyrchu brwyliaid.
Mae deddfwriaeth yn ei le ar hyn o bryd i leihau allyriadau amonia ar ffermydd dofednod. Nodir fod allyriadau amonia yn un o’r prif resymau dros wrthod rhoi caniatâd neu atal cynlluniau i ehangu. Mae siediau modern gyda gwell systemau awyru a gwresogi ynghyd â gwella’r sbwriel sy’n cael ei greu wedi lleihau allyriadau amonia, ond mae’n bosibl bod modd gwneud gwelliannau pellach drwy ddefnyddio ychwanegion.
Mae defnyddio ychwanegion sy’n lleihau amonia, naill ai drwy eu hychwanegu’n uniongyrchol at y sbwriel neu ei gyflenwi i’r adar drwy’r dŵr yfed, yn cynnig dull ychwanegol o leihau cynhyrchiant amonia ymhellach. Mae dau gynhyrchydd brwyliaid masnachol profiadol, gydag adeiladau modern a blynyddoedd o brofiad o gynhyrchu dofednod ar gyfer marchnad y DU, yn cymryd rhan yn y prosiect blwyddyn hwn i edrych sut y gall yr ychwanegion hyn leihau eu hallyriadau amonia.
