APROVECHAMIENTO DEL ENSILAJE DE PULPA DE CAFÉ (COFFEA ARÁBICA) EN LA ALIMENTACIÓN PORCINA COMO ESTRATEGIA DE GENERACIÓN DE VALOR EN LA CADENA INTERNA DE PRODUCCIÓN.

Abstract

The high production costs of pork, associated with an exponential increase in the feed inputs required for the raising and fattening process, have led to a shift towards alternatives aimed at increasing profitability in the pork business operation. Thus, the utilization of agro-industrial waste such as coffee pulp for pig feeding has gained increasing importance for pig farmers in the national territory. However, one of the limitations for its use in pig feeding is its content of antinutrients such as caffeine. Therefore, it is necessary to subject the pulp to a silage process with additives to reduce its content through fermentative degradation. Considering the issues, a bromatological characterization was conducted on a coffee pulp silage with urea and molasses as additives, evaluating its ash content (9.50 ± 0.01%), moisture (17.64 ± 0.01%), fat (1.65 ± 0.01%), protein (30.14 ± 0.01%), crude fiber (11.76 ± 0.01), NDF (88.91 ± 0.01), ADF (30.17 ± 0.01%), and caffeine (4.97 ± 0.01 mg/g). Finally, different percentages of substitution of coffee pulp silage (CPS) at 10%, 20%, and 30% were evaluated, and it was found that any selected percentage would offer a similar conversion to that of the control treatment. Therefore, a financial analysis was conducted, from which it was concluded that including a 30% substitution of CPS in the diet of pigs during their pre-fattening stage generates a significant increase in the profitability of the pork production process.
