| Descripció: | Introduction. Coffee husks have limitations for their use in animal feed due to the content of tannins, caffeine and lignin, which requires bioconversion with microorganisms, such as silage and depletion of the substrate with fungi that allow the bioconversion of lignocellulosic waste. Objective. To evaluate the effectiveness of coffee husk silage in reducing the caffeine and tannin content and the decrease in lignocellulolytic compounds due to substrate depletion with Pleurotus djamor. Materials and methods. In this study, two treatments of molasses were carried out for silage, 5% and 10% molasses, left for 160 days. Samples were taken in triplicate for chemical analysis on day 0 and at the end of ensiling, reducing sugars were determined. , protein, ash and fiber according to standardized procedures, cellulose by Kurschner and Hoffer, lignin by TAPPI 222 om-88, tannins by the FolinCiocalteu method, based on Makkar et al. A completely randomized design with a factorial arrangement was used, ANOVA and Tukey’s test were performed for the comparison of means, and calculations were also performed to determine the effectiveness of the treatments. Results. The silage process significantly reduced caffeine and tannins for both treatments, lignin was reduced by 55.87 and 43.97% respectively in each treatment. Conclusions. Bioconversion with P. djamor managed to reduce this compound, therefore, coffee husks become feasible as animal supplementation. |
