ABSTRACT
Twenty four Pelibuey × Katahdin male intact lambs (33.22±4.02 kg) were used in order to evaluate the effect of filtering-sanitization of water offered as drink water on growth performance, dietary energetics, carcass traits, and diarrhea frequency in finishing lambs. Lambs were fed with a cracked corn-based high-energy diet during 89-d. Treatment consisted in filtering and sanitization of raw dam water qualified as “clean and safe” comparing it as follows: 1) dam water (RAW), and 2) dam filtered-sanitized water (FILT). Water filtered-sanitized decreased three-fold total solids and remove coliforms, E, coli, and salmonella. Filtered-sanitized water increased 10% water intake, 8% daily gain, and 3% dietary net energy utilization. There was no evidence of infectious diarrhea during the experiment. Non-infectious diarrhea frequency and days on diarrhea were decreased 33% by FILT. Hot carcass weight (HCW) and longissimus muscle area (LM) were increased by FILT. Lambs drank FILT shown lower relative weight of stomach complex and tended (P=0.06) to have lower relative intestinal weight. It is concluded that reduction of TDS and the bacterial load in water qualified as “clean and safe” decreases frequency and days of diarrhea during diet period adaptation, promoting better diet energy utilization, improving weight gain, and HCW and LM area.
