“…The lower digestibility of DM, OM and CP recorded for the control treatment could also be attributed to the lower CP and higher NDF content of the basal diet, tef straw, which might have depressed rumen microbial function leading to slower fermentation of nutrients, while the contrary could have been true for the supplemented treatments (Ibrahim et al 1995). The lack of improvement in apparent digestibility of ADF and NDF due to supplementation in the current study agrees with other similar results (Ash andNorton 1987).…”

The experiment was conducted at Alamata Agricultural Research Center, Ethiopia using 20 Afar rams with an initial body weight (BW) of 18.2 +/- 1.76 (mean +/- SD) kg. The objectives were to study the effect of supplementation with concentrate mix consisting of wheat bran (WB), noug seed cake (NSC) and sesame seed cake (SSC) at the ratio of 2:1:1 on dry matter (DM) basis, respectively on feed intake, digestibility, BW gain and carcass parameters of Afar rams fed tef (Eragrostis tef) straw basal diet. The experiment was arranged with four treatments and five replications in a randomized complete block design. The treatments included feeding sole tef straw (T1, control), and daily supplementation with the concentrate mix offered at 150 (T2, low), 250 (T3, medium) and 350 (T4, high) g DM per head. Total DM intake, crude protein (CP) digestibility, daily BW gain (P < 0.001), DM and organic matter (OM) digestibility, and carcass parameters (P < 0.05) were higher in the supplemented than in the control treatment. Intake of tef straw reduced as the level of supplementation increased, whereas the contrary was true for CP intake. Performance in carcass parameters was better for the medium compared to the low level of concentrate mix supplementation. Moreover, the medium level of supplementation did not substitute tef straw intake. Therefore, it is concluded that the medium level of concentrate mix supplement maintained the utilization of the roughage feed and resulted in better carcass parameters.

“…It could be due to high lignin and silica contents in rice straw. Ibrahim (1995) reported that in vitro OM digestibility of rice bran was low caused by high lignin and silica contents. Leng (1990) defined that lowquality grass is indicated by low digestible value (< 55%) and low CP concentration (< 8%).…”

The aim of this research was to evaluate the nutrient degradability, in vitro methane (CH 4) production of several agricultural and food industry by-products in relation to their chemical composition. Twenty-one samples of 7 feedstuffs from agricultural and food industry by-products consisted of corn straw, potato straw, rice straw, cocoa pod, sago waste, rice bran, soybean curd residue were evaluated by an in vitro gas production and nutrient degradability. The feedstuffs varied greatly in their crude protein (CP), neutral detergent fiber (NDF) and non-fiber carbohydrate (NFC) contents. Crude protein ranged from 1.5 to 21.8%, NDF from 31.6 to 71.1% and NFC from 1.5 to 50.8%. Among the seven feedstuffs, soybean curd residue had the highest CP content, on the other hand it had the lowest NDF content. Dry matter (DM) and organic matter (OM) degradability were highest (P<0.01) in soybean curd residue among the feedstuffs. The CH 4 production was significantly higher (P<0.01) in rice straw, cocoa pod and corn straw as compared to sago waste. There was a strong positive correlation (r = 0.60; P<0.01) between NDF concentration and CH 4 production. However, the total gas productions was negatively correlated (r =-0.75; P<0.01) with NDF content. The CH 4 production of feedstuff is influenced by NDF content.

“…The reduced CF contents (Table 1) of the fungal treated substrates probably influenced improvement in OMD, since high NDF and ADL contents in feedstuffs result in lower fiber degradation (Van Soest, 1988). Additionally, tropical forages and concentrates feedstuffs have a large proportion of lignified cell walls with low fermentation rates and digestibility rates and limited intake (Ibrahim et al, 1995;Hindrichsen et al, 2001), this is also true of tropical agricultural wastes. The estimated ME were varied and particularly higher in the treated substrates.…”

Treatment of crop residues with some species of white-rot fungi can enhance the nutritive value. After the fungal treatment of sorghum (Sorghum bicolor) stover with two white-rot fungi in a solid state fermentation, the chemical composition and in vitro digestibility of the resultant substrate was determined. The results show a significant (p < 0.05) increase in crude protein contents from 2.54% for the control to 4.51% for Pleurotus ostreatus (POS) and 4.59% for Pleurotus sajor pulmonarius (PPT). The nitrogen free extract (NFE) content also increased significantly (p < 0.05). The crude fibre decreased significantly from 31.65% for the control to 27.49% for POS and 23.54% for PPS. There were also consistent significant decreases (p < 0.05) in the values obtained for NDF, ADF ADL. Significant differences were also observed in the hemicellulose and cellulose contents. Fermentation of the insoluble fraction (b) was enhanced by the fungal treatment. Wide variations were also observed in the mineral contents of the different substrates The estimated organic matter digestibility (OMD) ranged from 42.99 to 57.75%, short chain fatty acid ranged from 0.56 to 0.94 µM and metabolisable energy (ME) ranged from 5.97 to 8.21 MJ/Kg DM. This result suggests that fungal treatment of sorghum stover resulted in improved CP and digestibility, hence its potential in ruminant nutrition.
