Resumo: | This thesis presents two studies about evaluation of different levels of mastitis and their treatments besides analyzing the corresponding pain responses in dairy cows. The first study is about the effects of mastitis levels upon somatic cells count, pain thresholds and acute phase proteins concentration (APP): serum amyloid A (SAA) and fibrinogen. One hundred lactating cows were evaluated with different mastitis levels, being classified as follows: level zero (healthy cow), level 1 (subclinical mastitis first degree), level 2 (subclinical mastitis second degree), level 3 (subclinical mastitis third degree), level 4 (clinical mastitis). SCC of the milk from cows affected with clinical mastitis is significantly higher than milk from cows with subclinical mastitis at different levels, as well as healthy cows. Sensibility to pain is similar among clinical and subclinical mastitis, but cows presenting clinical mastitis show lower resistance to pain than healthy cows. Pain threshold measured in the hind limbs (right or left) is not affected by affected mammary gland side. Acute phase proteins (SAA and fibrinogen) are not affected by absence or occurrence of mastitis. The second study evaluated the non steroid anti-inflammatory (AINE) ketoprofen associated to antibiotic upon pain sensibility of cows affected by clinical mastitis. The pain threshold measured on the period without treatment was significantly lower than in the first day after beginning of the treatment, which was similar to the threshold measured on the second day after the beginning of the treatment, which was similar to that measured before the treatment. Variability in pain threshold among cows was larger at the period before the beginning of treatment, but it decreased on the first day after the beginning of the treatment. Cows with clinical mastitis and treated with AINE show reduction in pain sensibility just on the first day after the beginning of the treatment. Clinical mastitis cause pain in dairy cows, being needed more researches aimed at adoption of an efficient treatment to decrease pain sensibility to increase animal welfare. |

O primeiro refere-se aos efeitos dos diferentes níveis de mastite sobre a contagem de células somáticas, limiar de dor e níveis de proteínas de fase aguda (PFAs), amilóide sérica A (SAA) e fibrinogênio. Foram avaliadas 100 vacas em lactação com níveis diferentes de mastite, sendo assim classificadas: nível 0 - vaca sadia; nível 1 - mastite subclínica grau 1; nível 2 - mastite subclínica grau 2; nível 3 - mastite subclínica grau 3; nível 4 - mastite clínica. A CCS do leite de vacas com mastite clínica foi significativamente superior a de vacas com a doença nos diferentes níveis subclínicos, bem como a de vacas sadias. A sensibilidade à dor entre casos de mastite clínica e subclínica é semelhante e apenas vacas com mastite clínica apresentam menor resistência à dor do que vacas sadias. O limiar de dor nos membros posteriores, direito ou esquerdo, não sofre influência do lado da glândula mamária afetada pela mastite. As concentrações de PFAs, SAA e fibrinogênio, não são influenciadas pela ausência ou ocorrência de mastite. O segundo trabalho avaliou os efeitos da utilização do antiinflamatório nãoesteróide (AINE) cetoprofeno, em associação com antibiótico, na sensibilidade à dor de vacas acometidas por mastite clínica. Verificou-se que o limiar de dor no período sem tratamento foi significativamente menor que no primeiro dia após o início do tratamento e este, por sua vez, não diferiu do limiar no segundo dia após o início do tratamento. No entanto, o limiar, dois dias após o início do tratamento também não diferiu do limiar no momento sem tratamento. Observou-se uma maior variação nas respostas de limiar de dor das vacas no período que antecedeu ao tratamento, com redução desta no primeiro dia após iniciado o tratamento. Vacas com mastite clínica tratadas com AINE apresentam redução na sensibilidade à dor apenas no primeiro dia após o início do tratamento. A mastite clínica causa dor em vacas leiteiras, sendo necessários mais estudos visando adotar tratamentos eficientes na redução da sensação dolorosa para assim atender ao bem-estar animal.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em ZootecniaUFPelBRFaculdade de Agronomia Eliseu MacielBovinos de leiteMamiteLimiar nociceptivoDairy cattleMastitisThreshold nociceptiveCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAAvaliação da mastite e seu impacto sobre a sensibilidade à dor em vacas leiteirasMastitis evaluation and its impact upon sensibility to pain for dairy cowsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesishttp://lattes.cnpq.br/8769373816455770http://lattes.cnpq.br/5700216426341087Fischer, Vivianhttp://lattes.cnpq.br/9221640062810564Silveira, Isabella Dias BarbosaPeters, Mônica Daiana de Paulainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALtese_monica_daiana_de_paula_peters.pdfapplication/pdf790918http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2620/1/tese_monica_daiana_de_paula_peters.pdf5864e184e9f5f8ef1a064bd0c1a8a344MD51open accessTEXTtese_monica_daiana_de_paula_peters.pdf.txttese_monica_daiana_de_paula_peters.pdf.txtExtracted Texttext/plain199224http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2620/2/tese_monica_daiana_de_paula_peters.pdf.txtaec5a789845778870d3470185ca8e156MD52open accessTHUMBNAILtese_monica_daiana_de_paula_peters.pdf.jpgtese_monica_daiana_de_paula_peters.pdf.jpgGenerated Thumbnailimage/jpeg1326http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2620/3/tese_monica_daiana_de_paula_peters.pdf.jpg051d5817664459583552d6b0c266dfceMD53open access123456789/26202019-08-20 11:28:49.031open accessoai:guaiaca.ufpel.edu.br:123456789/2620Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2019-08-20T14:28:49Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
