“…According to Lopes et al (2011), increased BMSCC can lead to direct economic loss to the producer, since a large portion of the dairies adopts payment according to the milk quality, a fact that directly affects the mastitis economic impact. In another study, Lopes et al (2012) verified that expenses with mastitis prevention represent a much lower cost compared to corrective measures and the production loss caused by increased BMSCC, which shows the advantages of investing in good milking handling practices that significantly contribute to the reduction of BMSCC, and consequently to reduction of the mastitis economic impact.…”

“…Changes in milk composition due to breast infections reduce the products nutritional values and raise processing problems, which can lead to products out of the desired quality standards. High values of BMSCC are also directly related to lower yield of the dairy production (Santos & Fonseca 2007, Lopes et al 2012). In addition, increased BMSCC due to intramammary infections (IMI) caused by certain mastitis pathogens, such as Streptococcus agalactiae, reduces the shelf life of milk and its derivates (Barbano et al 2006).…”

High bulk milk somatic cell counts (BMSCC) are indicative of failures related to the control of mastitis in the herd, which compromises the quality of the milk and generates great losses for the producers and for the industry. A case-control study was carried out in dairy herds in the Campos das Vertentes region, Minas Gerais State, Brazil, in order to contribute to the knowledge of the risk factors involved with elevated BMSCC. The study involved 46 dairy herds, of which 30 were considered cases (BMSCC ≥700,000 cells/mL of milk) and 16 control farms (BMSCC ≤200,000 cells/mL of milk). Sixteen qualitative variables and four quantitative variables were analyzed. The results showed that the risk factors for BMSCC ≥700,000 cells/mL were the presence of Staphylococcus aureus and Streptococcus agalactiae pathogens in bulk milk, non-use of pre and post-dipping, non-use of disposable paper towel for drying of mammary glands, non-monitoring of mastitis in the herd by means of California Mastitis Test (CMT) or individual somatic cell counts (SCC), non-implementation of the milking line and therapy of dry cows and failures in hygiene of teats and udders before milking. Moderate correlations were also observed between the elevation of BMSCC and counts of S. aureus and BMSCC and counts S. agalactiae in bulk milk, and a moderate correlation between S. aureus and S. agalactiae counts in bulk milk. Failures with regard to the maintenance and use of milking equipment, including manual pressure application in milking assemblies, unregulated milking vacuum pressure, and vacuum loss during milking, and maintenance failures of the milking machine and bulk milk tank were also pointed out as important risk factors of BMSCC elevation. The results of this study provided subsidies for the elaboration of more effective programs for mastitis control and improvement of raw milk quality, reducing the losses caused by the disease to producers and industry.
