Abstract

Thirty-six yearling Katahdin sheep and Boer and Spanish goat wethers were used to evaluate effects of level and length of water restriction. Moderate quality grass hay was consumed ad libitum with concentrate (80% corn, 20% soybean meal) at 0.5% BW. Baseline values with ad libitum water intake, used as covariates during restriction, were 26.9, 33.6, and 20.5 kg BW (SE = 0.90), 489, 812, and 491 g/d DMI (SE = 33.2), 969, 1,714, and 926 g/d water intake (SE = 100.3), and 305 mosmol in plasma (SE = 1.1; mean of samples at 07:00 h before feed and water were offered and at 13:00 h) for Boer, Katahdin, and Spanish, respectively. After the baseline phase, water availability was decreased by 10% every 1 (1X) or 2 wk (2X) to 40%, but also with 2 wk at 40% for 1X. There was an interaction in BW (measured three times weekly) between restriction treatment and level (P
