“…As expected, leaf particularly leaf blade contains higher CP than other fractions is in line with the literature. Compared with stem, leaf components of oat (Thiago and Kellaway, 1982;Shand et al, 1988), wheat (Åman and Nordkvist, 1983;Shand et al, 1988;Wales et al, 1990), barley (Ramanzin et al, 1986;1991;Herbert and Thomson, 1992) and grasses (Laredo and Minson, 1973;Poppi et al, 1981) were found to be more digestible. Moreover, the rate and extent of degradation of oat (Shand et al, 1988), wheat (Shand et al, 1988) and barley (Ramanzin et al, 1991;Herbert and Thomson, 1992) leaves were faster than the stem.…”

Five varieties of napiergrasses (Pennisetum purpureum) were fractionated botanically into leaf blade, leaf sheath, stem and head. Chemical composition of each of whole napiergrass and their botanical fractions were determined. Correlation, linear and multiple regressions between botanical fractions and nutritive value of varieties of napiergrass were also estimated. All botanical fractions differed due to the effect of variety. Napier Pusha contained the highest proportion of leaf blade and internode, but the lowest proportion of leaf sheath. Napier Hybrid contained the lowest proportion of leaf blade, but highest proportion of node. Consequently, napier Pusha contained the highest (p<0.01) crude protein (CP, 9.0%), but Napier Hybrid had the lowest CP (7.0%). Chemical composition of whole plant differed significantly (p<0.01; except NFE, p>0.05) due to the variety. Not only the whole plant, chemical composition of most botanical fractions of whole plant differed (p<0.05 to 0.01) due to the variety. The intrarelationships between leaf blade and leaf sheath was negative (r=-0.43). Leaf sheath was also negatively correlated to CP, but positively correlated to ash of whole Napier or their botanical fractions. Leaf blade, on the other hand, increases CP but decreases ash content of whole plant or their fractions. These results, therefore, suggest that napiergrass varieties differ widely in terms of botanical fractions and nutritive value, which may have important implications on intake and productivity of animals. Furthermore, napiergrass varieties should be selected for leaf blade only for a better response.

“…gram bran, rice husk, rice bran, wood dust and apple pomace [28]. The best substrate for xylanase production was wheat bran due to its nutritional content and large surface area [29], where wheat bran contained xylan and protein, which were served as carbon and nitrogen sources for microorganisms, respectively [30]. α-Amylase was also exhibited the maximum production by Clostridium thermosulforegenes using wheat bran [31].…”

Back groundFor enzyme production, the costs of solid state fermentation (SSF) techniques were lower and the production higher than submerged cultures. A large number of fungal species was known to grow well on moist substrates, whereas many bacteria were unable to grow under this condition. Therefore, the aim of this study was to isolate a highly efficient strain of Bacillus sp utilizing wheat bran in SSF and optimizing the enzyme production and soluble carbohydrates.ResultsA local strain Bacillus megatherium was isolated from dung sheep. The maximum production of pectinase, xylanase and α-amylase, and saccharification content (total soluble carbohydrates and reducing sugars) were obtained by application of the B. megatherium in SSF using wheat bran as compared to grasses, palm leaves and date seeds. All enzymes and saccharification content exhibited their maximum production during 12–24 h, at the range of 40–80% moisture content of wheat bran, temperature 37-45°C and pH 5–8. An ascending repression of pectinase production was observed by carbon supplements of lactose, glucose, maltose, sucrose and starch, respectively. All carbon supplements improved the production of xylanase and α-amylase, except of lactose decreased α-amylase production. A little increase in the yield of total reducing sugars was detected for all carbon supplements. Among the nitrogen sources, yeast extract induced a significant repression to all enzyme productivity. Sodium nitrate, urea and ammonium chloride enhanced the production of xylanase, α-amylase and pectinase, respectively. Yeast extract, urea, ammonium sulphate and ammonium chloride enhanced the productivity of reducing sugars.ConclusionsThe optimization of enzyme production and sccharification content by B. megatherium in SSF required only adjustment of incubation period and temperature, moisture content and initial pH. Wheat bran supplied enough nutrients without any need for addition of supplements of carbon and nitrogen sources.

“…The silica content greatly differed between the highest value of 3.68 percent in JHO 2004 and the lower of 2.54 percent in JHO 822 varieties of oat forage. Thiago and Roy (1982) reported that silica content in stem, leaf sheath and head oat straw was 0.2, 1.8 and 1.4 percent, respectively. Damame et al (2020) [9] reported similar results in the oat cultivar Phule Harita that percent silica content was increased significantly and lodging percent declined after the application of silica @ 400 Kg ha -1 .…”

The present investigation was carried out to understand effect of soil application of silica on biochemical parameters in relation to lodging tolerance in oat. Initially, two each lodging and nonlodging type oat cultivars were compared based on biochemical parameters in the pot culture experiment. The guaiacol peroxidase activity, polyphenols, lignin, potassium and silica were found higher in non-lodging than lodging type cultivars, whereas malondialdehyde content was found higher in lodging type cultivars. The effect of silica application @ 200 kg ha -1 and @ 400 kg ha -1 on biochemical parameters was recorded in 12 different oat genotypes under the field condition. With the increase in silica application from 200 to 400 kg ha -1 , the activity of guaiacol peroxidase enzyme, total polyphenols, lignin, potassium and silica contents were increased, while malondialdehyde content was decreased over the control in all oat genotypes. Among the twelve oat genotypes, JO-03-91, RO-11-1-4, UPO-212 and JO-2 were found promising genotypes for lodging tolerance.
