Twelve rats were divided in two groups, each one composed with three females and three males. Water and food were available during 4h for both groups. The experimental phase, during the first 2h, the Group 1 was exposed to chow food, followed by 2h to food supplements in a solution diluted on 85ml of water. Group 2 was exposed to the same conditions but in an invested sequence; rats in the first 2h...
This study evaluated effects of sucralosa or glucose concentration over feeding behaviour and body weight. Twenty-four Wistar rats (3 months old at the start of the experiment) forming 2 groups, each one with six females and six males, were exposed to 2 kinds of solutions (sucralosa or glucose). Sucralosa and glucose group were divided in two subgroups, everyone with three males and females. Every...
