“…Similar to the results of this study, Kaitho et al (1998) also observed increase in total DM intake without increase in tef straw DM intake in Ethiopian Highland sheep supplemented with browse species. Butterworth and Mosi (1985) also reported improved total DM intake in sheep supplemented with NSC, though there was a decline in the intake of the basal diet.…”

“…The CP content of tef straw used in this study was higher than 4.5, 4.4, and 3.75% reported by Melaku et al (2004); Bonsi et al (1996) and Kaitho et al (1998) for tef straw, respectively, but lower than 7.9% CP reported by Degu et al (2008) for tef straw. Contrary to the low CP content, the NDF and ADF contents of tef straw were high.…”

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.

“…Tagasaste is a plant of important agronomic value, as fodder it produces considerable amounts of palatable nutritious greenfeed with high protein content (20-25%) (Kaitho et al 1998;Snook, 1996) and, in land recovery practices, is a profitable option for improving agricultural production on water repellent (hydrophobic) soils (Abadi- Ghadim, 2000), lowering watertables (Lefroy et al, 2001a, b) or increasing soil fertility (Unkovich et al, 2000).…”

Screening for plant growth-promoting rhizobacteria in Chamaecytisus proliferus (tagasaste), a forage tree-shrub legume endemic to the Canary Islands

Rhizobacteria with properties related to plant growth-promotion were isolated from the rhizosphere of the perennial legume Chamaecytisus proliferus ssp. proliferus var. palmensis (tagasaste) growing in field conditions. Samples were collected in two localities of the Tenerife Island: La Laguna and El Tanque, NE and NW at 600 and 1000 meters above sea level, respectively, and in two seasons, winter and summer. The strains were isolated by using culture dependent procedures, and identified by phenotypic (culturable and biochemical) and genotypic (ERIC-PCR fingerprinting) features. The rhizosphere isolates formed a diverse community of mainly Gram-negative bacteria, with members of genera Pseudomonas, Burkholderia and Sphingomonas being predominant. A high level of selectivity was found in the rhizosphere environment as compared to the non-rhizosphere soil where Gram-positives were more abundant. Species richness (number of species) and species abundance were related to the sampling season and the locality, thus, samples obtained in winter at both sites had larger counts than samples obtained in summer, and the higher species richness was found in La Laguna. The species Pseudomonas fluorescens showed the highest number of properties related to plant growth promotion (PGP): 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity, phytohormone production, nitrogen fixation, fungal growth inhibition and cyanogenesis, thus it seems to be the most suitable microorganism to be tested in PGP-field experiments.

“…Polysaccharide solubilising processes calling upon alkali-based agents have increased cell wall and sugar degradabilities in rice straws by facilitating microbial access (Schiere and de Wit, 1995;Harada et al, 1999;Nguyen et al, 2010). By-products from local gardening and the agro-industry have been supplied to provide rumen microbes with limiting nutrients in semi-intensive production systems in Africa and in Asia.The nutritional values of local leguminous trees and vegetables are well documented in this regard (Kaitho et al, 1998;El-Nor and El-Sayed, 2000;Orden et al, 2000;Pamo et al, 2007).In an in vitro experiment on the effect of rice straw ammoniation and supply of fresh lucerne extract -a model of legume supplementation -on rumen metabolism, we observed that at low input levels of lucerne extract both ash-free NDF (NDFom) and ash-free ADF (ADFom) degradabilities tended to be lower with treated rice straw (e.g. 0.30 v. 0.46 for ADF), whereas at higher input levels they were not modified by straw treatment (Broudiscou et al, 2003).…”

The combined effects of lucerne (Medicago sativaL.) extract supplementation and ammonia treatment of rice straw (Oryza sativa, variety Thaibonnet) on the ruminal digestion of cell wall components were investigated in six continuous culture systems using a randomised complete block design. Data were fitted to second-order polynomial models. Untreated rice straw had higher contents of ash-free cell wall residues (CWR; 763v.687 g/kg dry matter (DM)) and non-cellulosic sugars (191v.166 g/kg DM) than treated rice straw. Ammoniation preferentially removed xylose, which resulted in a lower xylose-to-arabinose ratio (5.1v.5.8). In absence of lucerne supplementation and ammoniation, degradability coefficients were 0.54, 0.46, 0.58, 0.54, 0.42 and 0.60 for cellulose–glucose, xylose, arabinose, galactose, mannose and uronic acids, respectively. Both factors had significant effects on the microbial degradation of structural polysaccharides. With lucerne extract at an optimal level, ammonia treatment increased ash-free cell wall degradation by more than 10%. The degradability coefficients were increased by ammoniation without any significant interaction with lucerne extract, except for glucose, whose degradability was mostly influenced by lucerne extract in a curvilinear way. The comparison of regression coefficients in cell wall and CWR models suggested that ammoniation improved the degradabilities of xylose, galactose and mannose by partly solubilising the corresponding hemicelluloses and by improving the susceptibility of the remaining fraction to microbial attack, whereas it increased the degradability of arabinose only by favouring microbial attack.
