Resumo: Shading pastures alters the animals' routine and may have an influence on their relationship with water. The objective was to assess the behavior of crossbred cows related to shade and the search for water in three systems: Full sun; Moderate shading and Intense shading. The experiment was conducted at Embrapa Agrossilvipastoril (Sinop/MT/Brazil) from summer 2017 to summer 2018. Behavior of dairy cows? observations were carried out in three typical days in each season, from 6 am to 6 pm. Univariate analyzes were performed by SAS® On Demand and multivariate (principal component analysis) by Excel. The full sun system stimulated a higher frequency of animals looking for the water trough and a longer stay around it, as well as a shorter stay in the shade combined with a lower frequency of animals in this location, being more associated with incident radiation than temperature and temperature and humidity index. When there was shade available in the shaded treatments, the observed relationships were just the opposite. Therefore, shading, even if moderate, contributes to lessen the discomfort of dairy cows caused by radiation; this radiation, which encourages animals to frequent and remain around water troughs.
