Diagnosis of clinical and subclinical mastitis in a rural property in Carambeí, State of Paraná

Abstract

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.

“…With the increased demand for food arising from the growing increase in the world population, it creates a challenge for the producer to produce more in the same space (Gabardo et al, 2020;Macoski et al, 2021;Clock et al, 2021). Alternative techniques and management come as a solution to this problem, one of them is the rational use of fertilizers to increase productivity and reduce costs.…”

Use of efficient microorganisms in agriculture

“…Currently, Brazil is considered one of the largest food suppliers in the world (Saath & Fachinello, 2018). Knowing that natural resources are limited, more sustainable food production methods are essential to ensure food security for the constantly growing population (Gabardo et al, 2020;EMBRAPA, 2021;Macoski et al, 2021;Clock et al, 2021).…”
