Evaluation of african star grass (Cynodon nlemfluensis) silage quality when mixed with three different additives
Evaluation of african star grass (Cynodon nlemfluensis) silage quality when mixed with three different additives. The characteristics of african star grass (Cynodon nlemfluensis) silage, as well as its fermentation process when adding, at levels of 0%, 2% and 4% of the dry matter, molasses, ground corn or dehydrated citrus pulp, upon non-chopped, fresh forage, dumped and compacted on plastic bags commercially available. The experiment was carried on at the Universidad de Costa Rica’s Alfredo Volio Mata Experimental Station, using a nested factorial experimental design. Average values of 23.68%, 22.21% and 23.52% of DM; 9.98%, 9.89% and 10.58% of CP; 71.72%, 73.12% and 72.26% of NDF; 44.95%, 47.30% and 46.73% of ADF; 2.58%, 2.46% and 2.58% of EE; 10.08%, 10.31% and 10.34% of ASH were obtained when molasses, ground corn or dehydrated citrus pulp, respectively, were used. Also, average losses of 14.97%, 16.84% and 14.82% of DM; 4.39%, 5.24% and 3.82% of CP; 4.82%, 5.38% and 4.91% of NDF; 3.68%, 3.90% and 3.34% of ADF; 2.46%, 3.91% and 2.48% of EE; as well as 3.96%, 4.02% and 3.32% of ASH were found, respectively, on the molasses, ground corn and dehydratedcitrus pulp treatments. No relationship was found between the additive used, or the inclusion level used, and effluent production from the silages (p>0.05). Finally, organoleptic evaluation of all analyzed silages were excellent.
