Digitaria eriantha is a South African perennial grass, C4 type, that grows during
spring and summer with rainfalls higher than 400mm. The aim of this paper was to evaluate
its nutritional quality profile: Crude Protein ( %CP), True Protein (%TP), Soluble Protein
(%SP), Non-Protein Nitrogen (%NPN), Neutral Detergent Fiber (%NDF) and Acid Detergent
Fiber (%ADF) in cumulative production cuttings during a species cycle. In-sacco technique
was applied to estimate the degradability of dry matter (DM). A simple regression statistics
method was applied to relate different nutritional parameters. Digitaria eriantha presents low
percentage of CP from flowering and of NPN during its whole cycle. TP represents more than
40% of CP. The estimated effective degradability is lower than the determined with in-sacco
technique and it is related to the increase of NDF and ADF and with decrease of the TP as
cycle progresses.
