Cow mastitis is a common and frequently-occurring disease in dairy cows. This disease not only affects the development of the cattle industry, but also indirectly affects the supply and quality of milk. Then why are dairy cows so susceptible to mastitis?
Environmental conditions such as cattle sheds, cattle beds and sports grounds are muddy, cattle bodies and around the udder are too much dirt, sanitary conditions are too poor, the temperature is too high or too low, and milking conditions do not meet the physiological requirements of lactation, etc., resulting in cattle infected with mastitis.
Staphylococcus aureus, Streptococcus and Escherichia coli are the main pathogenic bacteria. In recent years, the incidence of mastitis caused by mycoplasma and fungi has increased year by year.
Cows in the peak period of lactation or milk production is too high, the body energy is in negative balance resistance, the relative incidence of aging cattle, multiple birth cattle is high.
Milking is not carried out in strict accordance with the milking procedure, the breast is not cleaned before milking, the milkman's hands are not cleaned, manual milking is not trained, the vacuum degree and pulse frequency of mechanical milking are too high or too low, and the milking machine is not cleaned and disinfected strictly, all of which create conditions for pathogenic bacteria to enter the breast, thus causing mastitis.
First, do cattle and environmental health
The bacteria that cause mastitis either exist in the body of the cow or in the environment where the cow is located. Therefore, it is very important to do a good job in the body and environmental hygiene of the cow. For example, the cow bed should be kept dry and no feces or urine should be accumulated, and the bedding grass should also be kept dry, clean and soft. The sports ground should be smooth and smooth to keep it dry. Disinfect the cattle barn environment and the sports ground regularly. In addition, pay attention to postpartum care, the discharge of lochia to minimize the pollution of the cow's hindquarters.
Secondly, the hygiene of milking parlors
Milking parlors are the easiest place to spread mastitis between cows, so keep milking parlors clean at all times. In addition, the milking machine is also an important cause of mastitis. Cattle farmers before milking, after milking must choose qualified bath use, reduce somatic cell count, prevent mastitis.
