mastitis-the holy grail?, page-2

Mastitis is one of the most important diseases affecting dairy cattle in Australia. The disease is widely distributed and has a very high incidence in most herds resulting in a great economic loss through a lowering of milk yield and the adverse effect on the products made from milk of infected cattle. It is natural therefore that the legislature should have framed laws and laid down regulations to deal with the diagnosis of this disease and to have placed restrictions on the use of milk from animals infected with micro-organisms likely to cause mastitis.
