The study aims to characterize the histological parameters of the small intestine of bovine slaughtered on the plant of Tunja - Boyaca, relating height, width, and quantity of hairiness with the nutrients absorption surface, in order to establish better diets, health and nutritional handling, as well as associate the digestive pathologies most commonly shown in our region cattle. For the study methodology, they were taken random samples of (n = 15) animals slaughtered for a week and taken samples of their small intestine (duodenum) of 1 x 1 cm. They were preserved in formol at 10 % and sent to the pathology laboratory of the National University in Bogota, where it was applied the hematoxilina-eosina (H-E) staining, included previously in paraffin blocks. Strips were analyzed in the laboratory of base sciences of the Foundation Juan de Castellanos, using a Model microscope with a 10 x increase in the lens. Measurements were taken on millimetres (mm) values. It is concluded that in the observed field there are 4 hairiness with an average height of 0,521 mm and width of 0, 10 mm. As the intestinal hairiness are located close to the cranial portion of the small intestine they were observed more abundantly in each field, longer, more uniform and wider, which increase its internal surface, facilitating the digestion processes and absorption.
