T he role of drinking water in productive efficiency and health in small ruminants is well known (NRC, 2007).However, drinking water can be a transport of contaminants and bacterial that can affect animal health and productivity.In this sense, several studies have been conducted to determine the impact of high total dissolved sol-ids (TDS) concentration and bacterial count load in drink water on performance and health of ruminants.High concentration (>1000 mg/L) of TDS and infectious bacterial (> 100 CFU/mL) can reduce growth performance and health (mainly scours; Rinella et al., 2021).Then, when water had lower TDS (<1000 mg/L) and bacterial count load Short CommunicationAbstract |Twenty four Pelibuey × Katahdin male intact lambs (33.22±4.02kg) 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.
