A study was carried out with the objectives to evaluate the raising system deep-bedding (wood shavings and rice husk), in comparison to the traditional concrete floor in the raising of swine during the growth and finishing phases and to evaluate the animal performance based on BGTHI (Black Globe Temperature and Humidity Index), in the weight gain, ration intake, feed conversion and the water consumption. A total of 216 animals (Landrace <FONT FACE=Symbol>´</FONT> Large White) was used, divided in 12 uniform lots, each one with 18 animals, sheltered in 12 independent pens, in way that each set of four pens was kept in differentiated raising system. The experiment was conducted using complete randomized block design with four replications per raising system. A discrete advantage of concrete floor for weight gain, ration intake, feed conversion and the water consumption was observed.Therefore, the animal performance was not influenced by the raising systems, even so the animals kept in the concrete floor has showed resulted slightly better that the lodged deep- bedding. The beds appear as satisfactory option to provide total cleanness water economy of concrete floor and to prevent the discharge of residual water in the water courses.
