Testing for preference demonstrates higher consumption of both water and Ensure in Slc6a8^-/y mice, and greater intake of Ensure over water in Slc6a8^-/y mice. Day 1 testing with 50% Ensure for (A) consumption and (B) preference. Day 2 testing with 25% Ensure for (C) consumption and (D) preference. Day 3 testing with 5% Ensure for (E) consumption and (F) preference. Data is presented as mean + standard deviation. P values of ≤ 0.05 are shown with one (*) asterisk, ≤ 0.01 are shown with two (**), between 0.0001 and 0.001 are shown with three (***), and P values less than 0.0001 are shown with four (****).
