Shadow Rural Affairs Minister Samuel Kurtz MS has used the Pembrokeshire County Show as an opportunity to call again for changes to cattle slaughter rules in Wales.
Currently, in-calf cows and heifers who fail bovine TB tests must be culled on farm before giving birth to their calf.
Kurtz has long called for increased flexibility, allowing farmers to isolate the in-calf animal and for it to give birth with dignity before being culled.
Speaking ahead of the Pembrokeshire Show, Samuel Kurtz said:
"Bovine TB has been a defining issue for farmers in West Wales for over 12 years, affecting farm businesses, farmers' mental health and animal welfare.
"To know that farmers often see their in-calf cows and heifers slaughtered on their farms, in front of their eyes, with healthy calves drowning in their dead mother's womb, is a horrific situation which needs to change immediately.
"I'm calling once again on the Welsh Government to give farmers the flexibility to isolate cattle who have failed tests on farms, allowing them to give birth to healthy calves with dignity. This increases our animal welfare standards and reduces the massive mental health impact on our hard-working farmers.
"Farming in Wales needs a friend, and I will continue to be that friend, offering support and championing our incredible farmers and the work that they do."
