The experiment was carried out on january to april 2005, evaluating the ingestive behavior and physiologic parameters of lactating Holstein cows fed cactus forage associated with differents forage (sugarcane bagasse in natura, tifton grass hay, elephant grass hay, sorghum silage and sorghum silage plus sugarcane bagasse). Five cows were assigned to a 5x5 latin square design, after pre-experimental period of 14 days. Each experimental period lasted 14 days, 7 for adaptation and 7 for data collection and sample. The registration of the behavior variables was accomplished in a visual way, to intervals of five minutes, in 24 hours. The ambient temperature was monitored out hour in hour, of 6 the 18 hour, through bulb dry and humid thermometer. Rectal temperature and respiratory frequency were registred at 9 and 18 hours. The water intake was mensured at 5:30 and 17:30 hours. There was no significant difference (p>0.05) among the forage, that the physiologic variables, behavior, defecation, urination and seeks for water. There was difference (p<0.05) among the treatments for the afternoon and total water intake. In the conditions in that the experiment present was conducted, the association of the cactus forage with sugarcane bagasse, tifton grass hay, elephant grass hay, sorghum silage and sorghum silage plus sugarcane bagasse, influenced no behavior variables and physiologic variables but water ingesting influenced.
