Protein enrichment and digestion improvement of napiergrass and pangolagrass with solid-state fermentation
چکیده انگلیسی

Background and PurposeNapiergrass (Pennisetum purpureum Schumacher) and pangolagrass (Digitaria decumbens Stent) are two major forage grasses for cow feeding. They possess high yields and high regeneration properties. Inoculation of cellulolytic microbes on herbage could enhance the protein content of herbage and promote digestibility in chickens.MethodsCellulolytic microbes were isolated from various sources and cultivated on napiergrass and pangolagrass with solid-state fermentation for protein enrichment and in vitro digestion improvement.The fermented napiergrass and pangolagrass were used as the main protein source in chicken diets to assess the feasibility for non-ruminants feed.ResultsAfter a 42-day fermentation period, napiergrass showed higher protein contents (13.4–13.9%) than those of pangolagrass(11.1–11.7%). The in vitro digestibility of pangolagrass increased from 5.29% to 20.4%, whereas that of napiergrass increased from 5.29% to 19.0%. The average feed conversion efficiencies of chickens were close to the traditional fodder using corn as the main ingredient.ConclusionInoculation of appropriate cellulolytic microbes to enrich protein content and improve in vitro digestibility of herbage with solid-state fermentation for chicken feed is the prospective technique for agriculture, animal husbandry, and substantial management.
