Resumo: Subclinical mastitis is a disease of dairy herds that causes serious financial losses to the producer, resulting in reduced production and, in some cases, discarding of milk. Due tothis problem, the aim of this study was to evaluate the presence of mastitis in cattle of raw refrigerated milk producers in a total of 11 dairy farms in the southeast of Minas Gerais, Brazil, in 2012, and verify suitability to Brazilian StandardsIN-62.Duplicated samples were collected every month from April to November 2012 in 11 dairy farms in southwest of Minas Gerais, bringing a total of 188 milk samples. These samples were collected in cooling tank and stored in sterilized bottles preserved in bronopol for SCC testing and azidiol for coliform microbiological and TBC testing. Among all the analysed variables, SCC results from all the dairy farms differed most from the control group (p0.001). Consequently, according to legislation, all the dairy farms can be classified as contamination risk areas for subclinical mastitis considering that they all exceeded the limit values established by law. The analysed milk indicates lack of control for mastitis in the studied dairy farms.

Devido a esta problemática objetivou-se neste estudo avaliar a presença de mastite em bovinos produtores de leite cru refrigerado, produzido em 11 propriedades leiteiras do Sudoeste Mineiro no período 2012 e verificar a adequação à IN-62. Foram realizadas duplicatas de amostras mensais no período de abril a novembro de 2012 em 11 propriedades leiteiras do sudoeste mineiro, totalizando 188 amostras de leite. As amostragens de leite foram realizadas nos tanques de resfriamento, onde as amostras foram coletadas em frascos esterilizados com conservante bronopol para analise de CCS e com conservante azidiol para análise microbiológica de coliformes e CBT. Entre todas as variáveis analisadas, os resultados CCS de todas as propriedades foram os que mais diferiram com o controle (p ≤ 0,001). Desta forma, de acordo com a legislação todas as propriedades podem ser classificadas como áreas de risco de contaminação por mastite subclínica, todas as propriedades excederam os valores limites estabelecidas pela legislação.ILCTRigolin-Sá, OdilaFrança, NorivalCristiane Pereira Esper, Keylade Pádua Andrade, Douglas2014-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistadoilct.com.br/rilct/article/view/36810.14295/2238-6416.v69i5.368Journal of Candido Tostes Dairy Institute; v. 69, n. 5 (2014); 348-356Revista do Instituto de Laticínios Cândido Tostes; v. 69, n. 5 (2014); 348-3562238-64160100-3674reponame:Revista do Instituto de Laticínios Cândido Tostesinstname:Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)instacron:EPAMIGenghttps://www.revistadoilct.com.br/rilct/article/view/368/338Direitos autorais 2014 Revista do Instituto de Laticínios Cândido Tostesinfo:eu-repo/semantics/openAccess2014-11-08T10:22:43Zoai:oai.rilct.emnuvens.com.br:article/368Revistahttp://www.revistadoilct.com.br/ONGhttps://www.revistadoilct.com.br/rilct/oai||revistadoilct@epamig.br|| revistadoilct@oi.com.br2238-64160100-3674opendoar:2014-11-08T10:22:43Revista do Instituto de Laticínios Cândido Tostes - Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG)false
