ackground: The industrial by-products vary widely in the mineral composition, therefore is necessary to identify the composition of these products to determine if present risk of toxicity to animals. Heavy metals, once ingested, can accumulate in animal tissue, mainly in the liver, kidneys and muscles. Some elements such as arsenic, cadmium and mercury are often classifi ed as toxic elements because their biological activities are linked to toxic reactions, although all chemical elements, whether metal or not, can be toxic to animals if consumed in amounts above the need of each animal or for a long period. The protein soybean hull (PSH) is the residue coming from the technological process of extraction of soy protein, with is originally called primary sludge. To this is added 50% soybean hull and dried, resulting in the product called protein soybean hull. This work was carried out in order to assess through mineral studies the nutritional potential of the protein soybean hull for feed sheep in replace soybean meal, because currently there is no available scientifi c studies on the effect of using protein soybean hull in the ruminant animals diet related to mineral metabolism.Materials, Methods & Results: For this, samples of soybean protein hull were collected from a benefi ted soy industry in different batches to evaluate the variability in mineral composition of experim
