Resumo: | The objectives of this study were to evaluate the effect s of natural and artificial shade and sprinkling water on the physiologic responses (rectal temperature and respiration rate), and productive (fat, protein and somatic cells) of 20 Holstein-Friesian dairy cows, during the summer. The cows were divided in two groups and submitted for two environment (sun and shade) with and without water sprinkling before and after milking. Wind speed, temperature and relative humidity, black globe temperature and milk yield were recorded daily. Rectal temperature and respiration rate were measured twice weekly on the morning and evening; milk analyzed fortnightly. Respiration rate, milk yield and somatic cell number were affected (P < 0,01) for considered meteorological factors. Rectal temperature did not affect by treatments shade supply and water sprinkling showed to be profitable to the cows. |

As vacas foram divididas em dois grupos e submetidas a dois ambientes (sol e sombra) com e sem aspersão de água antes e depois da ordenha. A velocidade do vento, temperatura e umidade relativa, temperatura do globo-negro e produção de leite foram registradas diariamente. A temperatura retal e a freqüência respiratória foram medidas duas vezes por semana de manhã e à tarde; o leite, analisado quinzenalmente. A freqüência respiratória, a produção de leite e a contagem de células somáticas foram influenciadas (p < 0,01) pelos fatores meteorológicos considerados. A temperatura retal não sofreu influência dos tratamentos. O fornecimento de sombra e a aspersão de água mostraram ser benéficas às vacas.Editora da Universidade Estadual de Maringá2008-04-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/196110.4025/actascianimsci.v26i1.1961Acta Scientiarum.
