| Описание: | The aim of this study was to evaluate the replacement of P. purpureum var OM-22 for coffee pulp (25, 50, 75 and 100%) in the production of silage. The work was conducted from January to March 2015 in the central region of Chiapas, Mexico. Bites rate, consumption rate, bite size and preference index was measured on the animals; organoleptic variables: odor, color, moisture and texture and chemical composition through the analysis of crude protein, neutral detergent ber and acid, organic matter, ash, condensable tannins, cyanogenic glycosides, saponins and cafeine, also pH was evaluated in the silage. Data from quality and ingestive behavior were subjected to analysis of variance using the GLM procedure of SAS statistical package and the means were compared using the Tukey test (p<0.05). The results indicated that the incorporation of coffee pulp by 25 to 50% is feasible since the preference index (0.40 y 0.35) and consumption rate (10.20 y 8.81) was higher (p<0.05), in comparison with other percentages that resulted from the organoleptic characteristics of silage as well as the improvement in chemical quality in terms of crude protein and absence of secondary metabolites in general. |
