MOSQUERA PEREA, Dissa Enith; MARTINEZ GUARDIA, Mélida; MEDINA, Henry Hernán  e  HINESTROZA, Leidy Indira. Bromatological characterization plants species and by-products in the humid tropic of Colombia. Acta Agron. [online]. 2013, vol.62, n.4, pp.326-332. ISSN 0120-2812.

Nutritional potential was determined for livestock species of local resources attending it's chemical composition and digestibility proves in vitro of the dry matter (DIVDM) in leaves of Árbol del pan (Arthocarpus altilis Z.), pacó (Gustavia superba Kunth) and achín (Colocasia esculenta Linn), chontaduro shells (Bactris gasipaes Kunth) and banana shells (Musa paradisiaca L). Bromatological analyses included dry matter (DM), crude protein (CP), ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), lignin fiber (ADL) and gross energy (EB). Higher raw protein percentages (CP) and gross energy (GE) for Achín leaves, and Árbol del pan leaves with 27.78, 19.38% and 3911 and 3981 cal/g, consecutively, whereas DIVDM values were better for chontaduro shells and Achín leaves with 78.9 and 68.6%, respectively. In general, the resources at study show a nutritional value similar to the cultivated fodder, therefore, could be created a viable alternative to partial substitution to expensive source material in diets for farm animals.
