Intake of 10% ethanol solution, water, and total fluid, and ethanol preference in B6 and 129 mice fed one of three standard cereal-based diets (Teklad 8604, Zeigler NIH-07, and Purina 5001), a “breeder” diet (Purina 5015), or two purified diets (AIN-76A and AIN-93G). Values are means ± SEM, n = 15 or 16 per strain for each diet. The following differences were significant (P < 0.01; see also Table 4): Ethanol intake: B6 > 129; AIN-76A > AIN-93G; standard cereal-based diets > Purina 5015 or purified diets; B6 mice fed standard cerealbased diets > B6 mice fed Purina 5015 or B6 mice fed purified diets; Water intake: B6 < 129; 129 mice fed standard cereal-based diets > 129 mice fed Purina 5015; Total intake: standard cereal-based diets > Purina 5015 or purified diets; Ethanol preference: B6 > 129; AIN-76A > AIN-93G; standard cereal-based diets > Purina 5015 or purified diets; B6 mice fed standard cereal-based diets > B6 mice fed Purina 5015 or B6 mice fed purified diets.
