Background: Mastitis is a major cause of economic loss for the dairy industry. It frequently affects postpartum dairy cows that are permanently housed, irrespective of breed, age category and udder conformation. Aim: This study set out to evaluate the prevalence and annual incidence of clinical and subclinical mastitis in dairy farms in the mountainous region between Bejaia and Tizi Ouzou provinces. Methods: The trial was conducted under field conditions to demonstrate the value of the California Mastitis Test (CMT) for the early diagnosis of subclinical bovine mastitis. Four hundred cows from thirty-two small dairy farms, of different breeds and age groups, were screened using the CMT after a preliminary clinical examination. Screening took place from January 2019 to February 2020. Results: Two hundred and nineteen cows screened had at least one affected quarter, representing an overall prevalence of 54.75%. There were far more cases of subclinical mastitis (35.5%) than of clinical mastitis (17.25%). The CMT allowed for early diagnosis, otherwise two thirds of cases would have gone unnoticed. Conclusions: Early detection has the potential to improve veterinary healthcare, as well as reduce economic losses.
