The Agriculture Minister has allowed some trading to continue at marts - despite the Covid-19 crisis.
The Irish Farmers Association has welcomed this morning's announcement.
Normal mart activity was banned last weekend when the Taoiseach's announced new restrictions to stop the spread of coronavirus.
But this morning, Agriculture Minister Michael Creed says some services can continue at marts.
He says mart managers can facilitate the sale of animals in some circumstances.
A farmer can deliver calves to the mart, by appointment, and the mart can facilitate the sale.
For older livestock, the mart can also allow a deal between a buyer and seller, in specific circumstances.
Minister Creed says the measures will allow the food chain to be maintained - and protect animals' welfare.
But he says normal mart auction activity can't resume until further notice.
