Steve Evans has a dairy herd in Pembrokeshire and he's losing thousands of pounds every month because of Bovine Tb. He wants his cows free of the notifiable disease so he can get back to some form of normality and certainty. We join him as vets are onsite doing 2 different tests which will give him a more accurate idea of how many of his cows are carriers. However by doing so he risks losing 70% of his 500 strong herd and going out of business. He explains the frustrations of dairy farming in Wales. Here they don't allow the control of wildlife to minimise the risk of Tb infection which can happen when the cows are out in the pastures grazing during spring and summer.
