PREVALENCE OF BOVINE MASTITIS IN DAIRY HERDS AND IMPACTS ON MILK QUALITY

Abstract

The present study reports the prevalence and impacts of bovine mastitis in dairy herds in the state of Minas Gerais.Mastitis, an infectious inflammation of the mammary gland, is predominantly triggered by pathogenic microorganisms of the genera Staphylococcus spp. and Streptococcus spp., with the subclinical form being the most prevalent. This asymptomatic manifestation, responsible for approximately 42.82% of the cases analyzed, constitutes a significant risk factor, since it causes an increase in the Somatic Cell Count (SCC) and compromises the quality and productivity of the milk. The epidemiological analysis showed seasonal variations in the incidence of the condition and a correlation between increases in SCC levels and inadequate management practices, such as reduced milking frequency and poor hygiene. The improvement of milking techniques and the continuous monitoring of herd health biomarkers are crucial to reduce the occurrence of mastitis, since the findings reinforce the relevance of adopting prophylactic measures and early interventions to ensure the economic sustainability of dairy farms, animal health and milk quality.
