Resumo: | Effect of udder massage at the end of milking on residual milk and mastitis occurrence in dairy cows. Residual milk (RM) after milking is an important factor that can predispose cows to mastitis. In this study, the hypothesis that udder massage at the end of milking may reduce RM and the incidence of mastitis was tested in two experiments. Experiment 1 was conducted on an experimental farm with ten lactating cows (6,200kg/lactation) and experiment 2 was carried out on a commercial farm with 52 lactating cows (4,480kg/lactation). In both experiments the cows were paired by parity, stage of lactation and productivity, and they were randomly assigned to one of the treatments: massage or no massage of the udder at the end of milking, in two periods in a crossover design. The individual milk production of each cow was measured. Residual milk was collected and measured 2min after an oxitocin application. California Mastitis Test was used to detect the occurrence of subclinical mastitis. In neither of the experiments did udder massage have any effect on milk production (experiment 1 p > 0.41, n = 10 and experiment 2 p > 0.46, n = 12), on RM (experiment 1, 1.78 ± 0.45kg, n = 10; experiment 2, 2.42 ± 0.32kg, n = 12), or on mastitis incidence (experiment 2, chi-square; DF = 1; p > 0.68, n = 26). We conclude that udder massage at the end of milking has no effect on RM and does not affect mastitis incidence, at least under the conditions used in these experiments. |

Neste estudo foi testada a hipótese de que a massagem do úbere ao final da ordenha pode reduzir o LR e a incidência de mastite. Para tanto foram realizados dois experimentos, o experimento 1 foi realizado numa fazenda experimental com 10 vacas (6.200kg/lactação) e o experimento 2 em fazenda comercial com 52 vacas (4.480kg/lactação). Em ambos os experimentos as vacas foram pareadas por número de partos, estágio de lactação e produtividade e aleatoriamente destinadas a um dos tratamentos: com massagem ou sem massagem do úbere, em duas etapas num desenho “cross-over”. A produção de leite individual de cada vaca foi medida. O leite residual foi coletado e medido 2min após aplicação de ocitocina intravenosa. Foi usado o Califórnia Mastite Teste (CMT) para detectar mastite subclínica. Em ambos os experimentos a massagem não teve efeito na produção de leite (experimento 1, p > 0,41, n = 10; e experimento 2, p > 0,46, n = 12), nem no LR (experimento 1, 1,78 ± 0,45kg, n = 10; experimento 2, 2,42 ± 0,32kg, n = 12), e nem na incidência de mastite (experimento 2, qui-quadrado, p > 0,68, n = 26). Concluiu-se que, nas condições do experimento, a massagem no úbere não teve efeito no LR e nem na incidência de mastite.Universidade Federal de Santa Catarina2009-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2009v22n1p12910.5007/2175-7925.2009v22n1p129Biotemas; v. 22 n. 1 (2009); 129-1342175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2009v22n1p129/18753Copyright (c) 2011 Marcela Cristina Agustini Carneiro da Silveira, Luiz Carlos Pinheiro Machado Filho, Maria José Hötzelinfo:eu-repo/semantics/openAccessda Silveira, Marcela Cristina Agustini CarneiroMachado Filho, Luiz Carlos PinheiroHötzel, Maria José2018-03-07T17:30:16Zoai:periodicos.ufsc.br:article/20535Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2018-03-07T17:30:16Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
