“…This breaks down the polysaccharides into less complex carbohydrates for optimum utilization. The decline in crude fibre values agrees with previous studies where rice husk and wheat straw were fermented with Pleurotus spp [22,26]. The decrease in the values of crude fibre may also be as a result of the utilization of carbohydrates by the fungus as an energy source for mycelia growth as explained earlier for NSP [11].…”

“…In addition, antifungal properties of some bacteria might have inhibited the potential of Pleurotus ostreatus as the fermentation time increased [21,22]. The increment of 44.17% in CP for the 7 days fermentation period compared favourably with the results obtained by other workers [4,5,6,22]. This is an indication of the potential biodegradable effects of Pleurotus ostreatus on cheap ligno-cellulosics and low-grade agro-wastes, with bioconversion to protein-rich products.…”

“…The xylanase and other hemicellulolytic enzymes of Pleurotus ostreatus have the capacity to biodegrade the cell wall structure and their residue after expiration of life span or termination of fermentation added as cell protein to the substrate. In addition, antifungal properties of some bacteria might have inhibited the potential of Pleurotus ostreatus as the fermentation time increased [21,22]. The increment of 44.17% in CP for the 7 days fermentation period compared favourably with the results obtained by other workers [4,5,6,22].…”

Native rice husk (NRH) was fermented with Pleurotus ostreatus for 7, 14 and 21 days to improve the nutritional values. The proximate composition and amino acid profiles were determined. The results showed that crude fibre (CF), nitrogen free extract (NFE), acid detergent fibre (ADF), and neutral detergent fibre (NDF) were significantly higher (p<0.05) in the NRH (with values 13.37%,42.93%, 17.45% and13.42%, respectively) while corresponding lowest values of 12.14%, 34.26%, 12.27% and 12.41% were obtained in the 14 days samples. Crude protein (CP) was significantly highest (p<0.05) in the 7 days fermentation (12.37%) but lowest in the 21 days (7.94%). The nitrogen free extract (NFE) values were similar and higher (p<0.05) in the NRH (control), 7 and 21 days fermentation that is 42.93%, 40.37% and 39.53%, respectively. The calculated metabolizable energy (ME) was similar and higher (p<0.05) for the fermented native rice husk at 7, 14 and 21 days that is 2289.19, 2308.77 and 2328.59 kcal/kg, respectively. Dry matter (DM), ash, calcium and phosphorous values were not influenced (p<0.05) by the fungi treatment of the NRH. Essential amino acids (EAA) values viz; lysine (4.94 g/100g), valine (7.34 g/100g), threonine (4.81 g/100g), isoleucine (4.83 g/100g) and phenylalanine (5.59 g/100g) were higher (p<0.05) in the 14 days fermentation with p. ostreatus while others that are non-essential amino acids (NEAA) in this group include alanine (7.06 g/100g) and tyrosine (4.12 g/100g). Glycine (6.02 g/100g), serine (5.18 g/100g), proline (4.85 g/100g), leucine (7.44 g/100g), glutamate (14.54 g/100g) and arginine (8.51 g/100g) values were higher (p<0.05) in the 21 days while aspartate (8.70 g/100g), histidine (2.37 g/100g), methionine (2.69 g/100g), tyrosine (4.20 g/100g) and cystine (2.09 g/100g) were higher (p<0.05) in the 7 days treatment. All the amino acids with the exception of glycine, alanine and aspartate had lowest (p<0.05) values recorded in the native rice husk. The total amino acids (TAA), total essential amino acids (TEAA), total non-essential amino acids (TNEAA) were all significantly higher in the 7 days fermentation (95.43, 45.01 and 50.42, respectively) and the lowest values in the NRH. Percent EAA followed the same trend while %NEAA was highest in the NRH. Fermentation of native rice husk for 7 days improved its nutritive value and consequently increased its usage as a component of livestock feed.

“…Living beings which use cellulosic materials for their carbon and vitality source could be abused for the transformation of these squanders into items that are helpful to man. Case in point, waste cellulosic materials give perfect substrates to the development of mushrooms while the growths can thus debase the stringy squanders and add parasitic protein to the spent substrates [46][47][48]. Recuperation and re-utilization of waste cellulose has been a subject of far reaching examinations as a method for allaying vitality and sustenance deficiencies [49,50].…”

“…Fungi have been shown to have cellulase enzyme which can degrade the fibre in cassava peel thereby making available more energy to monogastrics from hydrolysis of the fibrous materials (Belewu and Banjo, 1999;Raji et al, 1988;Sani et al, 1992). This ultimately promotes weight gained and overall improved performance (Atteh, 2000;Abdulrashid et al, 2007).…”

Cassava peels which is available in large quantity as waste is being considered as a possible replacement for maize in chicken feeds due to the world shortage of cereals. This study examined the safety of collagen and reticulin fibres in the liver and kidney of broiler chicken, when the Aspergillus niger-hydrolyzed cassava peel meal (HCPM) was used as diet carbohydrate. HCPM was used as replacement for maize in chicken feeds at 0, 25, 50, 75, and 100%, respectively and were fed for 42 days. The animals were sacrificed and the liver and kidney were excised and fixed immediately in 10% formolsaline for 48 h. The tissues were processed for paraffin embedding. Sections were cut at 3 microns, dried for 30 min at 60°C and were stained using both Gordon & Sweet and Masson's Trichrome methods. The result showed the preservation of the reticulin and collagen fibres up to the 50% inclusion of HCPM as replacement for maize. The implication is that; the use of HCPM will make available for human consumption, half of the world maize cereals been consumed by the poultry birds.
