Pleurotus ostreatus Can Significantly Improve the Nutritive Value of Lignocellulosic Crop Residues

Improvement in the nutritive value of corn stover after solid-state fermentation with Pleurotus ostreatus is reported. Two ruminally cannulated dairy cows were used an vitro study arranged a 2 × 3 factorial design four replicates using P. ostreatus-treated stover. The increase crude protein (58.5%) and ash (25.8%) contents treated significantly higher (p < 0.001) than control. Results suggest potential microbial synthesis due to consistent mass yield (106–681%), irrespective incubation time. fiber components stover, except lignin, reduced 0.05), non-fiber carbohydrates increased by 118% samples. There was significant both dry matter disappearance (40.9–240%) total VFA (5.85–11.2%). Treatment time interaction for propionate production (9.37–14.0%), indicating that rumen pathway preferred. Acetate concentration (1.76–4.01%), which also resulted 7.09–11.42% decrease A:P ratio. Overall, results showed improved increasing its energetic values, protein, mass, volatile fatty acid concentrations.
