				Abstract 
 
				
				
				Aim: 
				
				This investigation is placed in the context of continuity of a 
				preliminary study already published; it was conducted in cattle, 
				sheep, goats, horses, and dogs; the main aim is to reveal and 
				develop criteria for the animal species determination based on 
				the morphometric parameters of red blood cells. 
				
				
				Materials and Methods: 
				
				Blood samples were taken from the jugular vein; and the smears 
				were confectioned on slides immediately after the blood 
				collection and stained according to the May-Gründwald Giemsa 
				method. For the morphometric study, three parameters were 
				considered which are: The diameter, the circumference, and the 
				surface of erythrocytes; and measurements were achieved using 
				the OPTIKATM Vision Pro software. Statistical analysis was 
				performed by both analysis of variances and Student’s t 
				analytical tests. 
				
				
				Results: 
				
				The recorded data showed that the three morphometric parameters 
				of red blood cells are higher in dogs followed, respectively, by 
				those of horses, cattle, and sheep, whereas, the goats have the 
				lowest ones. In addition, the obtained results allowed us to 
				propose new reference values for the circumference and the 
				surface of erythrocyte in considered species. 
				
				
				Conclusion: 
				
				This investigation permit concluding that from a drop of blood 
				it is possible to characterize the different animal species, 
				taking into account the diameter, the circumference, and the 
				surface of erythrocytes. 
				
				Keywords:
