- Abstract
Good waste management allows the industrial field to reduce the environmental impact and reduce management costs in final disposal of waste. Currently, industries seek sustainable development as an opportunity for change, whose purpose is to promote the efficient assessment of industrial waste. For this reason it is necessary that current research is focused on finding alternatives to achieve it. In the tannery industry, organic waste gives way to a wide range of food products due to its high protein content. However, there are few studies on the technical feasibility to manage them sustainably. The objective of this project is to develop a balanced feed for pigs in the growth stage using meat generated in the company Curtiembre Renaciente S.A. that meets the nutritional requirements according to the National Research Council (1998). To produce this product, meat flour was obtained through deliming, bleaching, thermal hydrolysis, grinding and drying processes. Also, we proceeded to characterize physical, chemical and bromatological properties of the meat flour to know its pH, particle size, concentration of crude protein, ether extract, amino acids present, calcium, magnesium, digestible and metabolizable energy. With the data obtained, the balanced feed was prepared based on 4 formulations with 0% meat, 1% meat, 3% meat and 5% meat using linear programming. The balanced manufacturing process involved the reception of raw materials, sifting, weighing, mixing, pelletizing, drying, cooling and storage. Finally, a characterization of protein concentration and total calcium in the balance was carried out to statistically evaluate the influence of the incorporation of meat meal on said nutritional parameters. In the three formulations, the addition of meat meal did not influence the percentage of protein and calcium present in the balance, however, the incorporation of 5% meat meal is more similar to the theoretical value established in the restrictions.
