The effect of using separation/sedimentation/filtration-treated
The purpose of this study was quantifying enterobacteria and identifying Salmonella spp in wastewater treated by separation/ sedimentation/filtration, and evaluating its effect on nursery pigs. In Stage 1, a total of 40 samples were collected (i.e.: 2 weekly samples at each of four points [sedimentation pit and three filters] for 5 wk). In Stage 2, 24 pigs were assigned to three treatment groups (T1= filtered/chlorinated water, T2=filtered water, T3=potable water). The following variables were studied: daily feed intake, total feed intake, daily water intake, total water intake, feed conversion rate, body temperature, body weight gain, and clinical conditions. In Stage 1 no differences (P>0.05) were found in enterobacteria among water treatment stages, but S. enterica was isolated from 15 % of the samples. During Stage 2, daily feed intake differences (P
