Comparison of broiler flock daily water consumption and water-to-feed ratios for flocks grown in 1991, 2000-2001, and 2010-2011

Abstract

This study was conducted to determine what differences exist in average daily water consumption and water-to-feed ratios for 2010-2011 flocks as compared with flocks reared 10 and 20 yr ago at the University of Arkansas Applied Broiler Research Farm. Water is consistently overlooked as a vital nutrient for broilers though it is essential for metabolic processes within the bird and also accounts for a large majority of lean mass weight. Over the years, genetic advancement has continually pressed for improved intake, gain, and FE for the commercial broiler. However, it is also important to note how this has affected water consumption. Flocks were grown in commercial broiler houses with water consumption and feed input to the house recorded daily for the entirety of each flock. Daily water consumption and water-to-feed ratios were adjusted per 1,000 birds, with daily mortality taken into account, to standardize the data. Daily water consumption was significantly different between each group, with the 2010-2011 flocks consuming the greatest amount. Significant differences were also observed for daily water-to-feed ratios. Average daily gains were also evaluated and found to be significantly different. However, increased feed and water consumption does not seem be the sole reason for increased average gain. Therefore, based on these results, water intake has increased over the years for the commercial broiler. © 2013 Poultry Science Association, Inc.
