This study was carried out to characterise Pennisetum purpureum harvested from some selected locations in S outh-W estern Nigeria using microsatellite markers. Leaf parts of growing young elephant grass (Pennisetum purpureum) were harvested and immediately preserved in ethanol solution before DNA extraction. Two (2) SSR primers (CTM59 and Xtxp278) were used to assess genetic diversity in Pennisetum purpureum. The result shows that 72% of the molecular variations in the elephant grass exists within the population with 28% among the population; there were no unique characteristics among the Nine (9) populations. Nei genetic index ranged from 0.067 (lowest) observed between Isokan and Odeda populations to 0.158 (highest), between Ifedore and Ikoyi Populations. Morphological characterization showed moderate diversity with two major clusters and one minor cluster. Keyword: Elephant grass; cultivars; locations; markers

A trial was conducted to investigate the germination percentage and emergence potential of nine imported temperate forage germplasms at the National Animal Production Research Institute, Shika, Nigeria. The seeds consisted of seven grasses namely; Beefsteak plant (Fructus perillae), Sweet elephant grass (Pennisetum alopecuroides), Wild foxtail millet (Setaria viridis), Napier grass (Pennisetum purpureum), King grass (Pennisetum sinese), Chinese sorghum (Sweet sorghum) and Zea mexican schard (Purus frumentum) and two legumes namely; Chinese woad (Isatis tinctoria) and Chinese alfalfa (Medicago sativa). A laboratory germination test and pot emergence trial was carried out to ascertain their viability. The result of the experiment showed that Sweet elephant grass, napier grass and king grass recorded over 90 % germination and the least was 30 % in Chinese sorghum. Chinese alfalfa and wild foxtail millet had least germination percentage with 100 % Seed dormancy.Highest emergence rate, seedling length and seedling vigour indexwere observed in king grass than the other forage germplasms. The highest percentage emergence was obtained in king grass > sweet elephant grass > napier grass > Zea mexican schard > beefsteak plant > Chinese woad > Chinese sorghum, respectively. It was concluded that these forages can successfully be adopted as animal feed resources in Nigeria and therefore, recommended formulti-locational trials in all the ecological zones of the country.

SUMMARY This study evaluated the influence of the propolis ethanolic extract (PEE) on gas production and in vitro degradability of sheep diets. Five experimental diets (treatments) were evaluated: without addition of PEE; 6 mL PEE; 12 mL PEE; 24 mL PEE and 36 mL PEE/kg concentrate. The experimental diet consisted of 50% elephant grass (Pennisetum purpureum) and 50% concentrate. There was a quadratic effect (P <0.05) for the volumes of total gas production (Vt), gases produced by the rapid degradation fractions (Vf1), and for in vitro degradability at 120 hours (Deg120), where the lowest values of Vt, Vf1 and Deg120, were found for the inclusion of 9.4 mL PEE/kg concentrate. Gas production by fermentation of the slow degradation fraction (Vf2) presented a mean of 25 mL/g DM (P <0.05). The colonization time of food particles (λ) significantly reduced (P<0.05) with increasing inclusion of PEE. Thus, it can be concluded that the PEE up to the inclusion of 9.4 mL/kg concentrate was efficient in inhibiting in vitro total gas production and from the fractions of rapid degradation by 9.9 and 15.3%, respectively, in addition to promoting a reduction of 5.3% in degradability after 120 h incubation in diets with a concentrate: forage ratio of 50:50. Thus, the inhibition in gas production was proportionally greater than the reduction of degradability.

AbstractAdsorption of xylan on pulp is a potential method to improve its properties, especially refinability for high quality printing and writing (P&W) paper grades. In this study, elephant grass [Pennisetum purpureum(Schumach.)] xylan was used for this purpose. The xylan was extracted using cold caustic extraction (CCE) fromP. purpureumbrown pulp, produced by the Soda-AQ process (kappa 20). Xylan resorption was accomplished during the oxygen delignification phase of eucalypt [Eucalyptus globulus(Labill.)] pulp to avoid problems induced by the colour of the lignin-contaminated deposited xylan. Immunolabelling and enzymatic peeling methodologies were compared for the analysis of the spatial distribution of xylan in the fibre wall. The labelling appeared unevenly as faint and brighter patches on fibre surfaces. Increased labelling of xylan was detected on the samples with precipitatedP. purpureumxylan. The enzymatic peeling method using a total hydrolysis enzyme mixture yielded a composition gradient as a function of time, showing clear xylose (Xyl) enrichment in the very beginning of the reaction, reflecting hydrolysis of fibre surfaces. Pure xylanase and endoglucanase hydrolyses yielded different product patterns and kinetics compared to total hydrolysis, but interpretation of those results in terms of xylan localisation was not straightforward.
