Caiff y treialon eu cynnal yng Nghymru a Lloegr gan brysuro’r gwaith ar gyfer dechrau defnyddio brechlyn gwartheg erbyn 2025\.  

TB gwartheg yw un o’r heriau mwyaf cymhleth ac astrus sy’n wynebu’r maes iechyd anifeiliaid yng Nghymru a Lloegr heddiw.


Bu’n rhaid difa mwy na 12,000 o wartheg yng Nghymru’n unig oherwydd TB yn 2019\. Bydd brechlyn llwyddiannus yn gallu bod yn erfyn pwerus yn y frwydr yn erbyn y clefyd ar ôl cynnal y profion effeithiolrwydd a diogelwch angenrheidiol.


Caiff y treialon maes eu cynnal dros y pedair blynedd nesaf ar ran Llywodraeth Cymru, Llywodraeth yr Alban a Defra, yn dilyn 20 mlynedd o ymchwil arloesol i frechlynnau TB a phrofion diagnostig gan wyddonwyr y llywodraeth. Mae’r Athro Glyn Hewinson, Cadeirydd Sêr Cymru bellach yn y Ganolfan Ragoriaeth TB ym Mhrifysgol Aberystwyth yn parhau i chwarae rôl allweddol yn y gwaith pwysig hwn.


Dywedodd y Gweinidog:



> Mae cael gwared ar TB yn flaenoriaeth i Gymru. Rydym wedi bod wrthi’n datblygu’n rhaglen ers mwy na 10 mlynedd ac mae brechlyn wastad wedi cael ei weld fel erfyn pwysig nad ydym wedi gallu manteisio arno eto.  
> 
> 
> Dros y 10 mlynedd diwethaf, rydym wedi gweld 44% o ostyngiad yn nifer yr achosion o TB ac rydym yn gweithio at gael ei wared yn llwyr erbyn 2041\. Gallai brechlyn ein helpu yn hynny o beth.


Dywedodd Prif Swyddog Milfeddygol Cymru, Christianne Glossop:



> TB gwartheg yw’r her mwyaf rydym yn ei wynebu o ran iechyd anifeiliaid. Mae’n destun trawma aruthrol i ffermwyr a chymunedau cefn gwlad.
> 
> 
> Rydym wastad wedi dweud y gallai brechlyn fod yn rhan bwysig yn y frwydr i ddileu TB. Diolch i flynyddoedd o ymchwil arloesol gan yr Asiantaeth Iechyd Anifeiliaid a Phlanhigion a gwaith yr Athro Hewinson, gallai’r treialon hyn roi erfyn arall i ni yn ein hymdrechion yn erbyn y clefyd niweidiol hwn.


Meddai Is\-ddirprwy Lywydd Cymdeithas Milfeddygon Prydain, James Russell:



> Mae potensial i frechlyn gwartheg dibynadwy o’i ddefnyddio gyda phrawf DIVA dilys weddnewid y sefyllfa yn ein hymdrechion i reoli a dileu TB gwartheg. Mae’n fater y mae arbenigwyr ein gweithgor ar TB gwartheg yn eu hadroddiad wedi’i nodi fel blaenoriaeth allweddol.
> 
> 
> Y treialon maes hyn yw penllanw blynyddoedd o ymchwil a gwaith arloesol gan filfeddygon gwyddonol i ehangu’r dewis o arfau sydd ar gael i filfeddygon a ffermwyr i drechu TB gwartheg.


Yn ôl yr ystadegau diweddaraf am TB yng Nghymru, mae nifer y buchesi sy’n cael achosion newydd o’r clefyd wedi gostwng 13% yn y flwyddyn ddiwethaf (12 mis hyd Ebrill 2020\) a gostyngiad o 9% yn nifer y buchesi sydd heb Statws heb TB swyddogol a gostyngiad o 5% yn nifer yr anifeiliaid gafodd eu difa oherwydd y clefyd.

The trials, which will take place in Wales and England, will enable work to accelerate towards planned deployment of a cattle vaccine by 2025\. 


TB is one of the most complex and difficult animal health challenges Wales and England face today. In Wales alone, more than 12,000 cattle were slaughtered in 2019 due to TB. An effective cattle vaccine has the potential to become a powerful tool in the battle against the disease following the necessary testing and safety and efficiency approvals.


The field trials will be conducted over the next four years on behalf of the Welsh Government, the Scottish Government and Defra, following 20 years of ground\-breaking research into bovine TB vaccines and diagnostic tests by government scientists. Professor Glyn Hewinson, now Ser Cymru Chair at the TB Centre of Excellence at the University of Aberystwyth continues to play a key role in this important work.


The Minister said:



> TB eradication is a priority for Wales, we have been building our programme for over 10 years and we have always seen cattle vaccination as an important tool, which is as yet, unexploited. 
> 
> 
> Over the last 10 years we have seen a reduction in the number of TB incidents of 44%, and are working towards TB freedom by 2041, cattle vaccination could help us achieve that.


Chief Veterinary Officer for Wales, Christianne Glossop, said:



> Bovine TB is the biggest animal health challenge we face. It causes significant trauma to our farmers and rural communities.
> 
> 
> We have always recognised vaccination could play a key role in TB eradication. Thanks to years of ground\-breaking research by the Animal and Plant Health Agency, along with Professor Hewinson, these new trials may provide us with another tool in our fight to stamp out this damaging disease.


British Veterinary Association Junior Vice President James Russell said:



> The deployment of a viable cattle vaccine used in combination with a validated DIVA test has the potential to be an absolute game changer in our efforts to control and eradicate bovine tuberculosis, and is something that our own expert bTB working group’s upcoming report has identified as a key priority.
> 
> 
> These field trials mark the culmination of years of ground\-breaking research and efforts by the veterinary scientific community to expand the range of tools available to vets and farmers to tackle bovine tuberculosis.


Latest statistics on TB In Wales, the overall number of new herd incidents of the disease is down by 13% in the last year (12 months to April 2020\), a 9% reduction in the number of herds not officially free of the disease and a 5% reduction in the total number of animals slaughtered due to the disease.
