Humans and animals share a deep relationship going back to early homo sapiens. With the exception of pets, in many cases we eat each other, but since humans have dominated the planet — normally we eat them. This has not been more the case than in livestock farming where animals are raised for food and are depended on for survival, not only for nutrition, but people’s livelihoods.
Many of the farms in the UK produce cattle and sheep for food. Endemic disease in livestock is a major global challenge, and could likely continue in future if something isn’t done to prevent livestock disease from growing and spreading in the first place.
While TB and foot and mouth catch the headlines, endemic diseases like Bovine Viral Diarrhoea (BVD) have been a major problem. 11% of BVD cases in Europe have been in the UK and the national cost has been estimated as high as £61m per year.
Whether livestock disease becomes a problem largely depends upon the practices of farmers and their advisers. Not all farming systems are the same and many of them have a history that goes back a long time. This means solving the problem of disease may not be solely down to applying the ‘right’ scientific or technological solution.
