Metabolic alkalosis in coliform mastitis

Area of Science:

• Veterinary Medicine
• Animal Physiology
• Biochemistry

Background:

• Coliform mastitis is a significant disease in dairy cattle.
• Understanding the metabolic disturbances associated with mastitis is crucial for effective treatment.
• Previous studies have indicated various biochemical changes in mastitis, but specific focus on blood gas and electrolyte balance in coliform mastitis is needed.

Purpose of the Study:

• To investigate blood gas, serum chloride, and potassium levels in dairy cows with coliform mastitis.
• To compare these values between normal, mild, and severe cases of coliform mastitis.
• To determine the utility of detecting metabolic alkalosis versus acidosis in severe coliform mastitis.

Main Methods:

• Tabulation of blood gas, serum chloride, and potassium values.
• Clinical assessment of 21 dairy cows diagnosed with coliform mastitis.
• Statistical comparison between different severity groups (normal, mild, severe).

Main Results:

• Severe coliform mastitis cases exhibited significant clinical signs, including anorexia and reduced digestive motility.
• Metabolic alkalosis was observed in severe cases, indicated by increased blood pH, hypochloremia, and hypokalemia (p < 0.01).
• These metabolic changes were significantly different compared to normal and mild cases.

Conclusions:

• Metabolic alkalosis is a key finding in severe coliform mastitis in dairy cows.
• Detection of metabolic alkalosis is a more accessible diagnostic indicator than acidosis in severe coliform mastitis.
• Monitoring blood pH, chloride, and potassium offers valuable insights into the severity and metabolic status of cows with coliform mastitis.
