Experiment 5: licks (means + SE) for soybean oil emulsions (1–10%) and vehicle during 3-min, 2-bottle tests conducted with CALHM1 knockout (KO) mice (n = 9; left) and wild-type (WT) mice (n = 10; right). The vehicle contained emulsifier and xanthan gum as did the soybean oil emulsions. Leftmost bars: 1% soybean oil emulsion and vehicle licks when animals were water restricted (WR). Right bars: 1–10% soybean oil emulsion and vehicle licks when the animals were food restricted. Numbers atop bars represent mean percent preference for soybean oil emulsion. *Significantly (P < 0.05) lower licks in the CALHM1 KO than WT groups. #Significantly (P < 0.05) higher licks for soybean oil emulsion vs. vehicle within groups.
