A study was conducted to evaluate the effect of biological treatments of sugarcane bagasse (SCB) and rice husk (RH) with three strains of white-rot fungi (WRF) (Pleurotusostreatus (Po), Pleurotusflorida (Pf) and Trichodermaviride (Tv) and effective microorganism (EM) on the chemical composition and in-vitro digestibility. The experiment consisted of 2x5 factorial arrangements, two levels of feed (SCB and RH) and five levels of biological treatments (Control, Po, Pf, Tv, and EM).Treatment of RH with EM, Tv, Po and Pf, significantly increased crude protein content from 7.90% in untreated to 7.92, 10.46, 10.61 and 11.35%, respectively. The corresponding increase in CP% of sugarcane from 2.61% was 3.41, 5.96, 5.89 and 5.95%.Treatments significantly (P<0.001) decreased neutral detergent fiber, acid detergent fiber, acid detergent lignin cellulose and hemicelluloses contents with the lowest value recorded for Tv. The IVOMD, IVDMD and metabolizable energy (ME) were significantly (P<0.001) increased. In conclusion, the study indicates that treatment of RH with Trichodermaviride and SCB with EM is more effective than others in improving the nutritive value of the roughages. We suggest evaluation of the treated roughages on animal performance.

Abstract Agricultural by-products such as corn stover (CS) are abundantly available in many countries; however, its high content of neutral detergent fiber (NDF) and lignin (L) and low protein content, causes low digestibility and nutrient availability for ruminants. The production of edible fungi could improve the digestibility of the CS because fungi can break down the cross-links between cell wall components. The aim of the study was to evaluate the effect of the invaded CS-based substrate used in the production of 21 white rot fungi of the species: Auricularia sp (Auri), Ganoderma sp (Gano), Hericium sp (Heri), Lentinula edodes (LC, L5, L9, L15, L21), Pleurotus eryngii (Pe-PQ, Pe-MB), Pleurotus djamour (Pd-Pro, Pd-UTMR) and Pleurotus ostreatus (Po-IAP, Po-Psma, Po-P14, Po-POS, Po-IE202, Po-JP, Po-P35, Po-P38, Po-Sfco) on crude protein (CP), NDF and L content and in vitro dry matter digestibility (IVDMD). The variables were analyzed in a completely randomized design with the MIXED procedure of SAS and the comparison of the means was made with the Tukey analysis. For CP, a significant increase (P &lt; 0.05) was observed from 10% (Pe-MB) to 41% (LC) in comparison with the substrate without inoculation (C). There was a decrease (P &lt; 0.05) of NDF from 2% (LC) to 10% (Pd-PRO) against C. Fungal treated CS had no effect on L (P &lt; 0.05) as compared to C. Treatments increased (P &lt; 0.05) IVDMD from 3% (L15) up to 36% (Po-POS) for all fungal strains, except for Pe-PQ and Po-Sfco in comparison with C. There was a positive correlation (r2=0.21, P &lt; 0.05) between CP and IVDMD. An equation was obtained to predict IVDMD [IVDMD=0.40578 + 358.38(%ADF)–358.02(%NDF)+358.17(%HEM)–0.3211(%DM), R2=0.32 (P &lt; 0.05)]. In conclusion the mycelial invasion of white rot fungi on a CS-based substrate, increased CP content, decreased NDF and improved IVDMD, making it a viable option to increase the digestibility of CS.

Fungal treatment has been recently considered as a promising method for improving the nutritive value of straw (Zadrazil et al., 1997). Several studies have been conducted to identify species of white-rot fungi for assessing their ability to improve the nutritive value of straw (Yamakamwa et al., 1992). Since there are many species of fungi in nature, there is an interest in characterising of some species. The objectives of this experiment were to study the effect of five Pleurotus fungi on the chemical composition, in vitro digestibility and in sacco degradability of wheat straw and evaluate their effect in upgrading the nutritive value of lignicellulosic materials.

ABSTRACT: This study was conducted to evaluate the effects of additives on the fermentation characteristics, chemical composition and in vitro digestibility of tetraploid black locust (TBL). The TBL leaves silage was either untreated (control) or treated with 1 × 106 cfu/g FM Lactobacillus plantarum (L), 1% glucose (G), 3% molasses (M), a combination of 1% glucose and Lactobacillus plantarum (L+G), or a combination of 3% molasses and Lactobacillus plantarum (L+M). Fermentation quality, chemical composition and nutrient digestibility were then analyzed. Ethanol and acetic acid concentrations were the dominant fermentation products in all silages except L+M silage. The L, G and L+G treatments failed to influence the fermentation. The M treatment increased (P<0.05) the lactic acid concentration and lowered (P<0.05) the pH when compared with control silage. The best fermentation properties were observed in L+M silage, as indicated by the dominance of lactic acid over ethanol in fermentation products. The M and L+M silages exhibited higher (P<0.05) dry matter, and M silage showed higher residual water-soluble carbohydrates than the control. Ensiling increased (P<0.05) the in vitro dry matter, neutral detergent fiber and acid detergent fiber degradability of TBL. Among the silages, M silage had the highest levels of dry matter, neutral detergent fiber and acid detergent fiber degradability. The obtained results suggested that application of lactic acid bacteria together with 3% molasses could be an effective strategy to prevent the occurrence of ethanol fermentation and improve fermentation quality of TBL silage; addition of fermentable sugars to TBL improves nutrient availability to ruminants.

Maize cultivation for silage could be a sustainable option in Boreal conditions, especially when combined with nutrient recycling. Effects of digestate (sludge from biogas of domestic origin) application in comparison with synthetic fertilizer and two maturity stages on chemical composition and in vitro digestibility of whole-crop maize were investigated. Starch, neutral detergent fiber, water soluble carbohydrate (WSC) and digestible organic matter (DOM) contents of maize did not differ in response to the two fertilizer treatments. However, starch, DOM and metabolizable energy of maize increased, while ash, crude protein and WSC contents decreased with increasing maize maturity. Heavy metals in maize fertilized with digestate remained low. The results indicate that whole-crop maize fertilized with digestate and harvested at 150 days after sowing is a promising feed and has good nutritive value, even in Boreal conditions.

Dry Matter Digestibility

Abstract Corn stover (CS) is an agricultural byproduct available in many countries for animal feed. However, due to its high lignin (L) and neutral detergent fiber (NDF) content it has a low digestibility. The production of edible fungi, using CS-based substrate, is an option to improve CS digestibility, as fungi can break down the cross-links between cell wall components. The aim of the study was to evaluate the effect of fungal treated CS from 17 species of white rot fungi: Lentinula edodes (L5, L9, LC,L15), Hericium sp (Heri) and Pleurotus djamour (Pd-Pro, Pd-UTMR) Pleurotus eryngii (Pe-PQ, Pe-MB), Pleurotus ostreatus (Po-IE202, Po-IAP, Po-Psma, Po-P14, Po-POS, Po-JP, Po-P38, Po-Sfco) on crude protein (CP), L and NDF content and in vitro dry matter digestibility (IVDMD). The composition of the substrate (C) was CS (80.55%), ground sorghum (5.98%) wheat bran (3.89%), corn gluten (4.89%), CaCO3 (3.89%) and CaSO4 (0.89%). The variables were analyzed as a completely randomized design using the MIXED procedure of SAS. Means were compared with the Tukey procedure. A significant increase (P &lt; 0.05) of CP from 10% (Po-P38) to 69% (LC) was observed, except for Pd-UTMR, Po-IAP, Po-Psma, Po-P38 and Po-Sfco that showed similar content to the C. There was a decrease (P &lt; 0.05) in the NDF from 10% (Heri) to 34% (L15) in relation to the C. The L content did not decrease in comparison with the C (P &lt; 0.05). Furthermore, 13 treatments significantly increased (P &lt; 0.05) IVDMD from 24% (Po-P14) to 42% (Pd-UTMR), except for Po-P38, Po-JP, LC and Heri in comparison with the C. In conclusion, the cultivation of white rot fungi, such as Pd-UTMR, Po-IAP, Po-Psma, LC, L9 and L15 using CS as substrate, improved CP content and increased IVDMD of CS, suggesting that which can be a good alternative for feeding ruminants.
