Pigs from a commercial crossbred genetic line were weaned at 21 days of age and transferred to pens in the nursery barn. Pigs received a standard commercial diet, three different rations (1, 2 and 3) being given continuously in feeders during the 28 days of the trial. The feed contained the following antimicrobials: chlortetracycline (Aureomycin® 220 G) in therapeutic doses as prescribed for protection of respiratory problems and penicillin G (Pen-P 110) at a metaphylactic dose as prescribed to prevent Streptococcus suis infections. Antimicrobials were used in feed as follows: chlortetracycline (1100 g/t) from day 0 to day 7; chlortetracycline (660 g/t), penicillin G (198.6 g/t) and IVOMEC from day 8 to day 14; and chlortetracycline (660 g/t) and penicillin G (198.6 g/t) from day 15 to day 28. On days 3 and 5 after weaning, all pigs received a circovirus (Circumvent® PCV) and mycoplasma (Myco Silencer® Once) vaccine, respectively. This study was conducted on 168 pigs. At day 0 (first day of placement in the nursery), the pigs were randomly divided into 2 groups: control (C) and supplemented (S). The control group received a standard commercial feed (basal diet) and the supplemented group received the basal commercial diet with 2% clinoptilolite.
Samples were collected at days 0, 2, 7, 14, and 28 after weaning, either directly from the rectum of the tagged pigs using a cotton swab or by pooling feces from five sites on the floor of the pens.
