HAHN-VON-HESSBERG, Christine M; GRAJALES-QUINTERO, Alberto  y  NARVAEZ-SOLARTE, William. Apparent Digestibility Coefficient of Common Fodder Plants in the Andean Region for the Feeding of Nile Tilapia (Oreochromis niloticus). Inf. tecnol. [online]. 2016, vol.27, n.4, pp.63-72. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642016000400007.

Digestibility coefficients of crude protein, ether extract, neutral detergent fiber, acid detergent fiber, calcium, phosphorus, nitrogen free extract and gross energy are evaluated in: Tithonia diversifolia, Xanthosoma sagittifolium, Trichanthera gigantea and Gliricidia sepium, supplied to Oreochromis niloticus. The digestibility coefficients were calculated using the indirect method, replacing 30% of the reference diet by the plant material to be analyzed, using the 0.5% Cr₂O₃, and distributing the treatments in a randomized block design. The results obtained for different ranges of digestibility coeficiente for crude protein were 89.94% - 98.66%; ether extract 87.73% - 98.79%; neutral detergent fiber 17.60% - 87.73%; Calcium 50.44% - 95.41%; phosphorus 72.21% - 93.75%; nitrogen-free extract 60.20% - 96.57%; gross energy 57.31% - 78.47%. In conclusion, Oreochromis efficiently digested forage plants, becoming an alternative supplemental ingredient for food in farming systems.
