“…The insignificant reduction recorded for groups G2 and G3 could be attributed to the recorded insignificant differences in intake of DM, CP and TDN as well as in nutrient digestibility parallel to the insignificant decrease in average daily gain. The present findings are disagree with the findings Items T1 T2 T3 T1 T2 T3 T1 T2 T3 of Fazaeli et al (2004), Kabirifard et al (2007), Khattab et al (2009), Omer et al (2012 and Shrivastava et al (2012), who reported a positive response in terms of nutrient utilization, nitrogen balance as well as body weight gain associated with utilization of biological treated crop residues in animal rations.…”

“…These results agreed with the findings obtained by El-Bordeny et al (2015), who observed insignificant differences among the different groups in nitrogen retention. On the contrary, Kabirifard et al (2007), Omer et al (2012), Shrivastava et al (2012) and Mahesh and Mohini (2013) found that using biological treated crop residues in animal feeding improve nitrogen efficiency of utilization.…”

“…During the last years, many efforts have been employed to increase their feeding values by biological treatments (Liu and Orskov, 2000;Zhu et al, 2005;Eun et al, 2006), which many studies indicated that the biological treatments tend to increase in vitro digestibility of tested materials (Zadrazil and Puniya, 1995;Sharma and Arora, 2010) and in vivo digestibility (Chen et al, 1995;Akinfemi et al, 2009;Arora and Sharma, 2009). Moreover, Fazaeli et al (2004), Kabirifard et al (2007), Omer et al (2012), Shrivastava et al (2012) and El-Bordeny et al (2015) reported a positive response in terms of nutrient utilization, nitrogen balance as well as body weight gain associated with using of biologically treated crop residues in animal feeding. However, little researches have been done to evaluate effect of inclusion biologically treated crop residues on animal physiological performance.…”

This study aimed to investigate effects of inclusion biologically treated rice straw with Trichoderma viride or Trichoderma reesei in ewe-lambs ration on its productive and some physiological response. Thirty crossbred (Rahmany X Romanof) ewe-lambs (three months old and 17±1.13 kg body weight) were assigned randomly to three groups (10 animals each). The first group was fed ration contained 55% concentrate feed mixture and 22.5% clover hay plus 22.5% Untreated Rice Straw (URS), group two and three were fed rations contained rice straw treated with T. reesei (TRSR) or T. viride (TRSV), respectively. No significant differences were observed in nutrients digestibility, Total Digestible Nutrients (TDN), nitrogen retention and nitrogen utilization efficiency among the experimental groups. Treatments did not record differences in TVFA's, ammonia concentration and pH value of rumen liquor at 0, 3 and 6 h post feeding. Also no significant differences were observed among the experimental groups in blood metabolites, while albumin, cholesterol and progesterone concentration increased (p<0.05) as animal age increased. Groups fed TRSV and TRSR recorded lower (p>0.05) values in total gain, average daily gain and worst (p>0.05) feed conversion as DM and CP compared to the control group. It could be concluded that using biologically treated rice straw in ewe-lambs ration had no adverse effects on nutrients digestibility and nitrogen balance as well as physiological response, while insignificantly decreased (p>0.05) growth performance.

“…This is not only because of the chemical composition of fibrous foods but also because of their low digestive potential in the animal's gastrointestinal system. These foods, under a biotechnology program using saprophytic fungi, could be modified to improve their nutritional quality by decreasing the cell wall content via digestion, and also by increasing nutrients obtained from the biomass of the microorganism growing on the incubated substrate (Kuhad et al, 1997;Shrivastava et al, 2012). Wheat straw (WS) and barley straw (BS) are important agricultural residues in the La Araucanía region and are usually burned or discarded.…”

“…The low digestibility of lignocellulosic fractions is due to lignin-covered polysaccharide microfibers, structured in a compact, crystalline, heterogeneous complex, where the lignin protects the polysaccharides against action by hydrolytic enzymes and other external factors, in addition to stabilizing the complex (Leonowicz et al, 1999;Villas-Boas et al, 2002). The high lignocellulosic content present in these agricultural residues and agroindustrial by-products inhibits the enzymatic action of the microbial community in the rumen, resulting in minimal degradation of organic matter, and consequently reduced availability of energy and nitrogen for the ruminal ecosystem (Sahoo et al, 2002;Shrivastava et al, 2012). Various techniques have been applied to improve the nutritional value of these fibrous foods, including physical, chemical and biological treatments (Liu et al, 1999;Tuyen et al, 2012).…”

A. Velásquez, P. Marnet, and R. Arias. 2015. Improvement in nutritional quality of fibrous food via in vitro digestion by Aspergillus niger. Cien. Inv. Agr. 42(1): 45-55. In a first experiment, the effect of in vitro incubation with Aspergillus niger (An) on the chemical composition of different fibrous substrates was studied. In a second experiment, the effect of incubation time (0, 72 and 144 h) on in vitro digestion with An of dry matter (IVDMD), neutral detergent fiber (DVNDF) and acid detergent fiber (DVADF) was evaluated for different substrates. Wheat straw, WS; barley straw, BS; oat hulls, OH; dehydrated alfalfa, DA; and dehydrated ryegrass, DB substrates were evaluated. In both experiments, incubations were performed in 250 mL Erlenmeyer flasks; 2 g of substrate was added to a culture medium (pH = 6), and incubated at 28 °C with constant ventilation. The An dose consisted of 3 mL of a solution of 5.3 × 10 6 spores mL -1 per flask. Incubation time for the first experiment was 144 h. After incubation, the contents of the flasks were homogenized in a blender for one minute. Subsequently, bromatological analysis was conducted without separating the An biomass. No interaction effects among any studied variables were observed. An incubation effected cell wall (NDF) and lignocellulose (ADF) content. An increase in true protein (TP) and soluble nitrogen (SN) was observed for all substrates tested, but responses differed depending on the type of substrate. The largest increases in TP were observed in DA and DB substrates (0.55 and 0.63% DM, respectively). IVDMD, DVNDF and DVADF were affected by the type of substrate and incubation time. The highest value of IVDMD 144 was observed in the DAAn treatment (49.47% DM), followed by the DBAn treatment, with a value of 45.51% DM. OHAn showed the lowest value of IVDMD 144 (29.38% DM). The results suggest that An possesses fibrolytic and metabolic potential for improving the nutritional value of fibrous foods through of the digestion of structural carbohydrates and the liberation of nitrogenous fractions embedded in cell walls, producing a change in the chemical composition and the potential digestibility of treated foods.

BACKGROUND: To date, fungus-assisted pretreatment of agricultural residue has not become the preferred method to produce protein-enriched and ruminally digestible animal feed because of low time efficiency of fungal delignification and protein production, i.e. the long solid-state fermentation period, and because of laccase as a potential inhibitor of cellulose activity. In this study, response surface methodology was employed to optimize the parameters in the process of producing nutritious animal feed from wheat straw with Inonotus obliquus pretreatment.RESULTS: The mineral salt solution containing (w/v) (NH 4 ) 2 SO 4 1%, MgSO 4 •7H 2 O 0.03%, KH 2 PO 4 0.011%, Tween-80 0.4%, and corn starch 10% with pH of 7.4 was optimized. Inonotus obliquus rapidly and completely colonized on wheat straw with an ergosterol content of 280 ∼g g −1 dry matter, consuming 45% of lignin after 15 days of fermentation, producing maximums of lignin peroxidase (1729 IU g −1 ), manganese peroxidase (610 IU g −1 ) and laccase (98 IU g −1 ) on days 5, 15, and 25, respectively. The crude protein (102.4 g kg −1 ) of 15-day fermented wheat straw increased by ~132%. After hydrolysis, the essential protein-bound amino acids (15.3 g kg −1 ) increased by ~47%, within which Met and Lys measured ~1070% and ~60% higher. The treatment with I. obliquus also improved the in vitro gas production after 72 h (IVGP 72 ) of wheat straw to 178.8 mL g −1 organic matter (~43% increase). CONCLUSION: For the first time, we found that I. obliquus is an effective white rot fungus turning wheat straw into ruminally digestible animal feed without laccase inhibitor.
