“…whereas Damasceno et al (2020) mentioned a 66.67% prevalence of clinical mastitis in herds in the South of Minas Gerais. These values are well above those found in the present study, which may indicate that the local management of control, prevention and treatment of clinical mastitis is being carried out effectively on the evaluated farms.…”

R es umo A falta da aplicação de boas práticas no manejo de ordenha pode resultar na ocorrência de uma das principais doenças que acomete o rebanho leiteiro no Brasil, a mastite. O objetivo deste trabalho foi avaliar a prevalência de mastite clínica e subclínica bem como avaliar a contribuição do manejo da ordenha nessa prevalência para que, dessa forma, se tenham subsídios que proporcionem um melhor controle da mastite em rebanhos leiteiros da região de Fernandópolis, São Paulo. Participaram da pesquisa 9 propriedades rurais, com 223 vacas em lactação. Todas as vacas em lactação foram avaliadas por meio da realização do teste da caneca de fundo escuro e CMT ("California Mastitis Test"). Além disso foi realizada observação da conduta do funcionário durante a ordenha, estrutura física da propriedade, manejo com os animais e tratamento das vacas secas. Os resultados obtidos foram tabulados, avaliados para elaboração de um fluxograma de ações de boas práticas. A prevalência de mastite subclínica detectada foi de 30,5%, sendo que, 66,7% possuíam ordenha mecânica e 89% tanque de expansão, mas 77,7% não efetuavam higiene dos equipamentos após ordenha. O pré e o pós-dipping não eram realizados por 89%, sendo que, 66,6% não faziam linha de ordenha e ninguém realizava testes de detecção de mastite. Conclui-se que a mastite subclínica está presente nos rebanhos avaliados. Pode-se observar o manejo adotado em cada propriedade e elencar os principais pontos críticos sendo eles relacionados principalmente a falhas de manejo e higiene de ordenha e equipamentos. A implantação do fluxograma de boas práticas de ordenha é de extrema importância para o produtor, uma vez que, o principal método para evitar e controlar a infecção é a prevenção.Pa la vr as-cha ve Fluxograma, higiene de ordenha, mastite, prevenção Abstrac tThe lack of application of good practices in milking management can lead to the occurrence of one of the main diseases affecting the Brazilian dairy herd-mastitis. This study was developed to examine the prevalence of clinical and subclinical mastitis as well as to evaluate the contribution of milking management to this prevalence, thereby providing bases for a better control of mastitis in dairy herds at Fernandopolis region, Sao Paulo State, Brazil The study involved nine farms with 223 lactating cows. All cows were evaluated by the stripcup test and the California Mastitis Test (CMT). In addition, the employees' conduct during milking; the physical structure of the farm; animal handling; and dry cow treatment were observed. Results were tabulated and evaluated for the development of a flowchart of good practices. Subclinical mastitis was detected in 30.5% of the farms; 66.7% perform mechanical milking and 89% have a cooling tank, but 77.7% do not sanitize the equipment after milking. Pre-and postdipping were not performed by 89%; 66.6% do not adopt a milking line; and none of the farms realized mastitis detection tests. In conclusion, subclinical mastitis is present in the evaluated herds. By observing the managem...

“…Damasceno and Silva (2020), classify the etiologic agents of bovine mastitis into contagious pathogens (Staphylococcus aureus, Streptococcus agalactiae, Corynebacterium bovis and Mycoplasma bovis), environmental pathogens (Streptococcus uberis, Streptococcus dysgalactiae, Streptococcus equinus, Escherichia coli, Klebsiella spp., Citrobacter spp., Enterobacter spp. and Pseudomonas spp.…”

The aim of the present study was to diagnose clinical and subclinical bovine mastitis in a property in the municipality of Carambeí-PR. 86 dairy cows were diagnosed in two evaluations carried out on July 23 and November 4, 2020. The detection of clinical mastitis was performed by testing the black-bottomed mug, whereas the detection of animals with sub-clinical mastitis by the California Mastitis Test (CMT) and laboratory analysis of bacteria and fungi present. In the first evaluation, 9.4% of the animals had mastitis, while in the second 5.16% of the herd. The milk of the animals that tested positive were submitted to laboratory analysis. In the first evaluation, they were diagnosed with an incidence of 15% Escherichia coli, 15% Prothoteca / yeast, 23% Staphlococcus aureus, 46% Streptococcus agalactiae. In the second evaluation, there was an incidence of 25% Enterococcus sp. and 25% S. agalactiae, the other animals showed 50% Staphlococcus non aureus. There was a higher occurrence of subclinical mastitis in the property, in both evaluations. There was a reduction from the first to the second evaluation in the incidence of cases of subclinical mastitis and the cases of clinical mastitis were resolved. Contributing to the lower disposal of milk caused by the high somatic cell count.
