Number of bacteria in dairy cows with breast cancer

Number of bacteria in dairy cows with breast cancer:
1. From the pollution inside the breast
Because cows with recessive mastitis have no clinical symptoms and the milk looks normal, it is often easy to be ignored and the milk of such cows is mixed into the cold tank. If the clinical mastitis is not completely treated, that is, although the clinical symptoms disappear, the bacterial cure rate does not reach 100%, and the remaining pathogens are mixed into the large tank milk by milking.

2. Pollution from the breeding environment
In the pasture barn, many environmental pathogens such as litter, sink, feces and soil will have contact with the cow's breasts, resulting in a large number of microbes attached to the breast, so if the milking cup is not used before the correct method Thorough medicated bath, cleaning and disinfection around the nipple, around the breast, and other parts of the body of the cow will result in the retention of contaminants such as dirt and feces around the breast and in the nipple tube, and eventually the bacteria will be mixed into the large tank milk by milking.

3. From milking equipment
Whether the milking equipment, including the milk cup, the milk tube, the milk storage tank, etc., has regular thorough disinfection has a great influence on the microbial content in the raw milk. For example, for an automatic milking production line, the number of microorganisms will increase sharply after the milking cup is squeezed, and the cup will fall during the operation. At this time, the cup is easily contaminated with the hind legs of the cow. Contact with the material causes pollution, which in turn contaminates the milk. In addition, if the rubber lining, milk tube and rubber gasket and other rubber parts are not replaced in time, cracks will cause the growth of pathogenic microorganisms.
