Evaluation of some biological parameters of Opuntia ficus indica. 2. Influence of seed supplemented diet on rats.
The present research was undertaken to evaluate some biological parameters in rats fed with a supplemented diet with Opuntia ficus indica powder seeds. Feed intake and body weight of rats were measured every two days during nine weeks of treatment. Digestibility, feed conversion efficiency and protein efficiency ratio were determined. No difference in digestibility was noticed between the different diets. The results indicated a significant decrease in body weight of rats receiving a diet partially substituted with O. ficus indica powder seeds, probably due to a significant decrease in serum-free thyroxin (FT(4)) compared to the control group. In the treated group, a decrease of glucose concentration in blood and an increase of glycogen in liver and skeletal muscle were noticed. A significant increase in HDL-cholesterol was noted in the group receiving the supplemented diet with O. ficus indica powder seeds. These results suggest that O. ficus indica seeds can be used as a healthy food.
