Animal and dietsThis research used an intervention design using 20 Wistar white rats (Rattus Norvegicus) weighing between 150 and 200 g, male, aged 8–12 weeks, of active and regular movement, and clear eyes. Preceding adaptation treatment was done to soothe the animals inside the individual cages in the position where they could interact audio-visually with each other. All groups were adapted for seven days in a row and given a standard diet. During the adaptation period, body weight was evaluated and animals that experienced an extreme decline in body weight were excluded. The intervention period was of four weeks duration. Food was given ad libitum per day with a commercial weft. Twenty rats were divided at random into four groups and fed with different doses of drink. White tea extract was mixed with fresh water at concentrations of 0.15 (G2) mg, 0.19 (G3) mg and 0.22 (G4) mg, respectively. The drink was given daily by using a syringe feeding method.
