Amid fodder shortages and environmental concerns in Morocco, this study explores a transformative livestock feed strategy. By combining olive pulp (OP) and wheat straw (WS) treated with Phanerochaete chrysosporium and Fusarium oxysporum, we enhance digestibility and sustainability. Five mixing ratios were examined: 100% OP (OP), 75% OP and 25% WS (MOP), 50% OP and 50% WS (OPWS), 25% OP and 75% WS (MWS), and 100% WS (WS). Fungal treatment and ratios influence cellulose-lignin dynamics. MOP increased cellulose (13.1), OP showed an initial decrease (-8.51, -5.88 for P. chrysosporium, F. oxysporum), with cellulose rising from 4 to 8 weeks, then declining. Lignin degradation differed (P < 0.001), P. chrysosporium was efficient (24.22%±13.75 to 31.57% ± 20.65), MWS remarkable, and OPWS stable. Mixed substrates showed higher IVTD_imp (58.56% ± 16%, 54.18% ± 20%, 36.83% ± 18%), OP and WS lower (26.25% ± 11%, 14.43% ± 7.48%). Enhanced IVTD (4-12 weeks) seen, OPWS and MOP excelling, WS lower. In conclusion, this study unveils the potential of fungal-treated feed optimization through substrate composition and tailored treatment durations. By leveraging synergistic effects and optimizing treatment timelines, we enhance livestock feed sustainability while addressing waste management concerns. This comprehensive approach holds promise for achieving both nutritional and environmental goals in livestock production.

This study aims to explore the synergistic effects of co-inoculation with Fusarium solani (F.s), Fusarium oxysporum (F.o), and Penicillium chrysogenum (P.ch) to enhance the digestibility and quality of lignocellulosic biomass for ruminant feeding. Wheat straw (WS), olive pomace (OP), and cedar wood (CW) were assessed as substrates. Results indicated varying impacts on lignin loss (L_loss), cellulose improvement (C_imp), and in vitro true digestibility improvement (IVTD_imp). F.o and P.ch co-inoculation exhibited the highest mean L_loss (53.74%), surpassing F.s and P.ch co-inoculation (18.23%) and F.s and F.o co-inoculation (19.23%). F.o_P.ch co-inoculation notably increased cellulose content (C_imp = 29.86 ± 18.19%) and IVTD_imp (40.74% ± 20.51%), while F.o_F.s showed minimal IVTD_imp (0.14 ± 11.42%). Substrates differed in fiber change and dry matter loss, with OP having the highest C_imp (25.6 ± 20.7%). Treatment duration influenced L_loss and IVTD_imp, increasing from 4 to 12 weeks. Co-inoculating F.o and P.ch enhances lignin degradation and biomass digestibility, improving their suitability for ruminant feed. Thoughtful selection of fungal combinations is crucial for optimizing co-inoculation. These findings support the utilisation of lignocellulosic biomass in ruminant feed.
