NORIEGA SALAZAR, Adrianyela; SILVA ACUNA, Ramón  and  GARCIA DE SALCEDO, Moraima. Chemical composition of coffee pulp at different silage times and its potential use in animal feeding. Zootecnia Trop. [online]. 2009, vol.27, n.2, pp.135-141. ISSN 0798-7269.

The objective of this work was to characterize the pulp of coffee, at different times, using chemical analysis and its potential use in animal feeding. The samples of pulp were drained during 24 hours, to eliminate the residual water coming from the benefit; then placed in a silo of 1.35 m3, which was totally covered with a black polyetilene plastic, to generate the natural fermentation. From the silos, samples were taken at 0, 90, 120, and 140 days after the pulp of coffee was obtained to conduct the chemical analysis. It was used a completely randomized design and for the means comparison was applied the least significance difference. The results showed means values of ashes 16.87%, ethereal extract 3.34%, tannins 0.23%, and protein 21.35%. At silage time increased, it was observed an increase in the concentration of ashes and tannins. Also, there were detected significant differences among times of silage (P≤ 0.05). In general, the time factor influenced on the chemical characteristics of the coffee pulp, which had a high nutritional value at 120 days of silage and it could be recommended potentially for animal feeding.
