Which instrument is used to detect mastitis in milk?
Milk checker is handy type instrument for cows to measure the electrical conductivity of milk in quarters of udder and to detect mastitis. When inflammation or other mammary disorders occurs, plasma constituents may exudate and cause changes in concentration of electrolytes contained in cow milk such as Na+, CL-, etc.
What are the symptoms of mastitis in dairy cows?
Moderate to severe clinical cases can be very painful and unpleasant for the cow. The most obvious symptoms of clinical mastitis are abnormalities in: The udder such as swelling, heat, hardness, redness, or pain; and. The milk such as a watery appearance, flakes, clots, or pus.
What is mastitis in dairy cattle?
Bovine mastitis is an inflammatory response of the udder tissue in the mammary gland caused due to physical trauma or microorganism infections. It is considered the most common disease leading to economic loss in dairy industries due to reduced yield and poor quality of milk [1].
What test is used to detect mastitis?
The California mastitis test (CMT) is widely used in the United States as a rapid “animal-side” assay that can be used in conjunction with clinical signs to identify mastitis. The basis for this test is lysis of somatic cells by the CMT reagent to precipitate the DNA and proteins contained in the cells.
How is mastitis diagnosed?

What is the cause of mastitis in cows?
Bovine mastitis is a condition typified by the persistent and inflammatory reaction of the udder tissue due to either physical trauma or infections caused by microorganisms. It is a potentially fatal mammary gland infection, that is most common in dairy cattle worldwide.
How do you treat mastitis in dairy cows?
Antibiotic therapy continues to play an important role in the control of mastitis in dairy cows. Lactational therapy is effective against Streptococcus agalactiae but less successful against infections caused by Staphylococcus aureus and other causes of mastitis.
What is the screening test of mastitis for dairy cattle in the milking process?
The California Mastitis Test (CMT) remains the only reliable screening test for subclinical mastitis that can be easily used at the cowside. The CMT was developed to test milk from individual quarters but has also been used on composite quarter milk samples and bulk milk samples.
