A) About cows

Mastitis:  is an inflammation of the mammary gland that can be caused by physical, chemical, mechanical or infectious factors. 80% of mastitis cases are caused by the entry of specific pathogenic microorganisms through the nipples and tissues of the udder; the remaining cases are the result of traumatic injuries, with or without invasion of microorganisms.

Babesiosis: it is a disease caused by a protozoa called Babesia SP., one of the many tick-borne diseases. Once the cow is infected, the disease is very difficult to control, due to the high cost of treatment. It usually affects milk production, but in some cases, in addition, if the cow's immune situation is not adequate, specimens may be sacrificed.

Brucelosis: it is an infectious disease, caused by the bacterium Brucella abortus, which mainly affects bovine females of reproductive age, causing abortions. Whole males can also become infected and in them the disease manifests with loss of fertility due to orchitis and epididymitis. This pathology is also a zoonosis (transmitted to humans) and causes an invalidating disease if not treated.

Salmonelosis: is an infection of the intestine that can cause severe diarrhea, pneumonia and high fever. Since an animal spreads, spread the Salmonella bacteria for 1 to 3 weeks with its manure. The presence of Salmonella in a company can be detected by analysis of the milk in the tank. Even in the most hygienic companies the bacterium can appear, through tiny portions of manure that come into contact with milk.

The disease of the hulls in cattle: is one of the main diseases affecting dairy cows. It is due to various causes that contribute to the installation of pathogens in the hooves, bones, ligasms and joints of the skin and subcutaneous tissues.
