ABSTRACT
With aim of place at the disposal of the laboratories nonconventional food with food values and which do not have impact on the system haematopoietic of the rats of laboratory in particular the rat of the species Rattus norvegicus, the study of the haematologic parameters of rats nourished with nonconventional food makes containing powder of Moringa oleifera was undertaken. Indeed, analysis of the blood taking away carried out following the administration of five diets container various rates of powder of Moringa oleifera (0% (Control food), 25%, 50%, 75% and 100%) respectively codified L3P, L3P25, L3P50, L3P75 and L3P100. These different food formulations were administered to rats (Ratus norvegicus) during three months. The weight of these animals was daily taken, followed by blood samples every 30 days for the determination of the blood count. The results of the study were shown differences between the various food formulations for each period of blood samples in biological parameters. These differences were more significant for platelets. During the three months of study, the hematocrit, platelets, MCV and outside the control group, were reported a slight progressive increase. The leukocyte parameters of all the rats in the investigation, indicated an increase in the second month. In conclusion, the study shows that during the three months of investigation, the tested foods do not disturb the haematological parameters except for thrombocytes which reveal a modification.
