Impact of drinking water filtration in the performance of finishing lambs
Abstract
Twenty-four Pelibuey × Katahdin lambs were used under a randomized complete block design to evaluate the impact of filtering drinking water on growth-performance. Treatments consisted of ad libitum supply of filtered dam water (FILT; 256 ppm TDS) and unfiltered dam water (RAW; 776 ppm TDS). The experiment lasted 89 days. Based on TDS content, both FILT and RAW qualify as "safe drinking water" for livestock. However, water intake was 10% higher in lambs receiving FILT. Moreover, FILT consumption improved daily weight gain (8%, P = 0.03) and dietary energy utilization efficiency (2.9% P = 0.04). The results of this study indicate that filtering the water qualified as "safe" improves the productive performance of finishing lambs.
