I consider the mandatory enhanced biosecurity measures of the AIPZ to be proportionate to the risk level posed by avian influenza here in Wales at this time.
Rwy'n ystyried bod mesurau bioddiogelwch gwell gorfodol yr AIPZ yn gymesur â'r lefel risg a berir gan ffliw adar yma yng Nghymru ar hyn o bryd.
