Rhaid ystyried gwerth maethol cig wrth gymharu olion traed carbon \u2013 dyna\u2019r neges allweddol o astudiaeth ddiweddar ar y cyd gan Hybu Cig Cymru (HCC), Prifysgol y Frenhines, Prifysgol Bangor a\u2019r Sefydliad Amaeth-Bwyd a Biowyddorau (AFBI). Roedd y papur gwyddonol, a gyhoeddwyd yn y cyfnodolyn Frontiers in Sustainable Food Systems<\/em>, yn canolbwyntio ar wahanol systemau o gynhyrchu cig oen \u2013 o systemau bugeiliol \u00e2 mewnbwn isel i systemau \u00e2 mewnbwn uwch wrth orffen pesgi. Hyd yn hyn, ni chafwyd unrhyw astudiaethau ynghylch effaith y diet pesgi ar \u00f4l troed carbon cig oen o ran maeth. Gwnaed y gwaith hwn gan ddefnyddio data o\u2019r prosiect Ansawdd Cig Oen Cymru.<\/p>\n

Dywedodd Swyddog Gweithredol HCC ar gyfer Datblygu Polis\u00efau a Phrosiectau yn y Dyfodol, Dr. Eleri Thomas, a gyd-ysgrifennodd y papur gwyddonol: \u201cRydyn ni wedi bod yn gweithio gyda Phrifysgol y Frenhines, Prifysgol Bangor ac AFBI ar gyfer y papur hwn ac mae\u2019r canlyniadau\u2019n newyddion gwych i\u2019r sector. Rydyn ni\u2019n gwybod fod systemau cynhyrchu cig oen dan bwysau cynyddol i leihau eu h\u00f4l troed amgylcheddol, yn enwedig allyriadau nwyon t\u0177 gwydr. Fodd bynnag, yn anaml y bydd y metrigau cyfredol a ddefnyddir i fynegi \u00f4l troed carbon cig oen yn ystyried ei ddwysedd maethol a\u2019i gyfraniad at ddiet cytbwys mewn pobl.\u201d<\/p>\n

Gall cig oen fod yn ffynhonnell werthfawr o asidau brasterog amlannirlawn (PUFAau), megis asidau brasterog omega-3 ac omega-6, sy’n bwysig i iechyd pobl. Casglwyd data o 33 o ffermydd a oedd yn pesgi \u0175yn ar un o bedwar diet gwahanol: cnydau porthiant, porfa, dwysfwydydd, neu borfa a dwysfwydydd. Defnyddiwyd y data er mwyn amcangyfrif \u00f4l troed carbon y cig oen a gynhyrchwyd o bob system. Yna cafodd lefel y PUFAau mewn dau doriad pwysig o gig oen eu monitro, i ganfod yr \u00f4l troed carbon mewn uned o PUFA omega-3. Pan ddefnyddiwyd uned weithredol gonfensiynol yn seiliedig ar f\u00e0s, roedd gan \u0175yn\u00a0 a gafodd eu pesgi ar ddietau porfa yr \u00f4l troed carbon uchaf ar gyfartaledd; fodd bynnag, pan gyfrifwyd y cynnwys omega-3 PUFA, y diet porfa oedd \u00e2’r \u00f4l troed carbon isaf ar gyfer toriadau o’r lwyn.<\/p>\n

Dywedodd yr Uwch Swyddog Gwybodaeth am y Farchnad, Ymchwil a Datblygu yn HCC, Elizabeth Swancott: \u201cFel arfer, wrth asesu \u00f4l troed carbon ffermydd, defnyddir unedau sydd yn seiliedig ar f\u00e0s, a all fod yn ddefnyddiol ar gyfer cymharu effeithlonrwydd systemau ffermio gwahanol; fodd bynnag, dydyn nhw ddim yn adlewyrchu sut mae systemau ffermio yn cael effaith ar wahaniaethau maethol y cynnyrch terfynol. Mae\u2019r astudiaeth hon yn dangos pa mor bwysig yw ystyried maeth wrth fynegi a chymharu olion traed carbon bwydydd fel cig oen, sy\u2019n cynnwys llawer o faetholion.\u201d<\/p>\n

Bydd y dull hwn yn helpu wrth ystyried y dietau gorau posibl ar gyfer systemau cynhyrchu cig oen \u2013 a hynny o safbwynt maeth pobl a chynaliadwyedd amgylcheddol.<\/p>\n
