It said the plans would help make farmers aware of nearby TB breakdowns and enable them to take precautions to reduce the risk to their cattle.
Deputy Minister for Food and Farming, Rebecca Evans, said: “There is currently no requirement for information about TB breakdowns to be shared with neighbouring farmers. This means farmers are unable to take sensible precautions, such as moving cattle to another field, to protect their animals from risk of disease.
“These proposals would allow farmers to make informed decisions on what they can do to protect their herds from TB.”
The consultation will run until January 30. Details of how to respond are set out in the consultation document which is available on the Welsh Government website.
