..it's just awful isn't it? I know that they cannot risk infecting the herds but as you say, disease control could be vastly improved as with some farming practices in some circumstances. I was just thinking back the other day, to the foot & mouth outbreak that saw thousands upon thousands of animals culled and the prion disease BSE in the 80s that destroyed so many herds. And on the TB front, the poor old badgers don't do well out of it either.
With all the money invested into animal health, you'd hope that effective dosing and containment strategies would come to the fore.
RIP all the animals slaughtered, for food, for disease, for overpopulation and that ethical slaughter and kinder means of doing so, could be implemented worldwide.
