The sericulture in Cauca department is a constant dynamic looking for strengthening different tiers of its productive chain. In the process of winding the cocoon, the pupa of the silkworm is generated as a by-product, which has not been accurately exploited. In order to evaluate the pupa and silkworm meal, as alternative sources to include in diets for animal nutrition, the compositional analysis was made from dry matter (%MSA), humidity (%HR), ash (%CNZ), crude protein (%PB), ether extract (%EE), chitin (%QTN) and in vitro digestibility of dry matter (% DivMS). For this purpose, we used fresh pupae (PGS) and pupal meal (PGSh), supplied by CORSEDA's farmers. The dry base results showed values of PB 50,05 and 51,73%; EE 41,36 and 37,62%; QTN 2,47 and 5,49%, for pupa and meal respectively. In terms of the digestibility of the dry matter, the pupa had a better performance with 84,73 against 77,45% corresponding to meal. The nutritional profile of the fresh pupa and meal allowed to determine that they are potential raw materials to be used in the formulation of balanced food for the animal industry.
