Number of bouts 1.10±0.10 1.67±0.19a 1.38±0.18 1.65±0.18
Total licks 2339±209 362±66b 2027±236 1414±224
Initial bout response rate (licks/min) 280±19 100±23b 250±20 178±21
Licks during initial bout 2325±206 265±44b 1948±263 1291±240
Milliliters consumed 12.0±1.0 1.8±0.3b 10.3±1.1 6.3±0.8

Values are shown as mean±standard error of the mean. A bout is a period of at least 25 licks, with no more than 2 min between licks.

a

Significantly different from day 1 sucrose by Mann Whitney U test (P<.05).

b
