Digestibilidad y energía digestible de la pulpa de café fermentada con Aspergillus niger en cerdos
The high costs of feedstuffs of diets for pigs and the human competion for them, has caused a great interest in researching about non conventional feedstuff such as the coffee pulp, which is in Colombia one of the most common crop byproducts which can be an important new alternative for feeding and improving the profits of the pig industry. In the "Centro Nacional de Investigaciones Agropecuarias Tibaitatá" (Colombia) an experiment was carried out to determine the true digestibility coefticients, digestible and metabolizable energy of the fermented and unfermented coffe pulp, using the mobile dacron bag technique. The statistical analysis was a completly randomized design with two treatments: the fermented and raw coffee pulp, with 80 experimental units in each one, each unit consisted of one gram of the feedstuff in both of the two treatments. The dry matter, organic matter, crude protein, NDF, ashes, tannins and intake energy, presented a high significant difference (P< 0.01) between the fermented and raw coffee pulp, showing a better nutritive value in the non fermented pulp. The better results obtained with the raw pulp as measured in percentages of digestibility was due to its lower lignin value. The digestible and metabolizable energy values were low, and if it were necessary to use coffee pulp in the pig feeding programs, an additional high energy feedstuff has to be included to compensate the low energy value of this feedstuff.
