This study aims to evaluate the intake, milk production and feeding behavior of dry matter (DM) and crude protein (CP) in goats in late lactation fed diets containing different levels of wet brewers (RUC): 0, 15, 20 25%. We used four Anglo Nubian goats distributed in a 4x4 Latin square. The four experimental periods lasted thirteen days, 8 of adaptation and five collection of data and samples. The roughage used was Tifton hay (Cynodon spp.) In forage: concentrate ratio 45:55. The animals were housed in individual stalls, fed twice a day. DM intake showed a linear effect of increasing levels of RUC diets with 0, 15, 20 and 25%, showing significant differences. There was a decrease in water intake, because the residue has a high moisture content. Milk production was not altered by the inclusion of the RUC, providing an alternative for animal feed. Diets catered RUC part of the water needs of the animals, tending to decrease water consumption. In the assessment of eating behavior were measured with the time spent feeding, ruminating time, integration and idle time were evaluated by method of observations of animals every 20 minutes to complete 24 hours. Variables rumination time (TR), food (TA), idle (TO) and interaction (TI) showed no significant differences, the values found with levels of substitution of the RUC did not provide differences from the control diet. The inclusion of the RUC to replace the protein source in diets did not affect milk production and feeding behavior, and recommended the use of 20% of RUC in the diet for meeting the requirements of DM, CP and TDN. In addition, diets RUC reduced water consumption by animals.
