Food preference. Male (n=6) and female (n=6) rats were provided with concurrent access to chow diet and to chocolate-flavoured pellets in the home-cage for 15 consecutive days. Chow and chocolate pellets left in the home-cage were weighed every 24-h. Data are expressed as the averaged % of total 24-h (kcal) intake (±SEM) consumed in the form of the chocolate-flavoured pellets by females (open circles) and males (closed circles) (a). On the right, the first two bars show the means of chow (white) and chocolate (black) preference over 14 days in males. The second set of two bars show the means of chow (white) and chocolate (black) preference over 14 days in females (b). *p<0.05 compared with chocolate preference.
