Effect of treating maize cobs with a combination of urea and wood ash (WA) on chemical composition, in vitro gas production, and in sacco degradability were examined in a previous study. The treatments were: (100U) =100% urea +0% wood ash, (75U25WA) = 75% urea +25% wood ash, (50U50WA) = 50% urea +50% wood ash, (25U75WA) =25 % urea + 75% wood ash and (0U0WA) = Untreated maize cobs. It was concluded in the study that, treatment 25U75WA gave better results in terms of all the parameters measured. This study aimed at determining the effect of feeding Twana sheep diets whose grain was substituted with maize cobs treated with 25%U and 75%WA on nutrient intake, digestibility, nitrogen utilization, rumen NH3, pH and performance. Tswana sheep were fed experimental diet whose maize grain was substituted with graded levels of 25U75WA in the dietary ingredients and the treatments were: 100M = 100% maize grain, 66M34C = 66% maize grain plus 34% treated maize cobs, 34M66C = 34% maize grain plus 66% treated maize cobs and 100C = 100% treated maize cobs in a 4×4 Latin Square Design (4 animals were rotated in 4 periods for all the treatments). Treatment 34M66C had crude protein intake (CPI), dry matter intake (DMI), organic matter intake (OMI) and neutral detergent fibre intake (NDFI) of 0.1334, 0.9500, 0.8921 and 0.4800 kg/d respectively (P<0.05) while the crude protein digestibility (CPD), dry matter digestibility (DMD), organic matter digestibility (OMD) and neutral detergentfibre digestibility (NDFD) were 79.57, 68.02, 66.26, and 57.8% respectively (P<0.05). All the treatments had similar (P>0.05) rumen NH3 ranging from 23.55 – 24.00 mg/ml while rumen pH were different (P<0.05) and ranged from 6.117 – 6.937 however treatment 100M had lower pH. Treatment 100M and 34M66C had average daily gain (ADG) of 0.1150 and 0.1417 kg/d, respectively (P<0.05), however, treatment 100M had lower feed conversion ratio (FCR) of 5.217 compared to 7.059 (P<0.05) for 34M66C. It was concluded that farmers should include 34M66C in the diet of Tswana sheep for optimum performance and also reduce the cost of feed.     Effet du traitement des épis de maïs avec une combinaison d'urée et de cendres de bois (CB) sur la composition chimique, la production de gaz in vitro et dans la dégradabilité de SACCO ont été examinées dans une étude précédente. Les traitements étaient: (100u) = 100% urée + 0% de cendre de bois, (75U25CB) = 75% d'urée + 25% de cendres de bois, (50u50wa) = 50% d'urée + 50% de cendre de bois, (25U75CB) = 25% d'urée + 75% de cendres bois et (0U0CB) = épis de maïs non traité. Il a été conclu dans l'étude que, le traitement 25U75CB a donné de meilleurs résultats en termes de tous les paramètres mesurés. Cette étude visait à déterminer l'effet de l'alimentation des régimes de moutons Twana dont le grain a été substitué aux épis de maïs traité avec 25% U et 75% de CB sur l'apport nutritionnel, la digestibilité, l'utilisation de l'azote, le rumen NH3, la performance de la pharmacie. Les moutons de Tswana ont été nourris à une alimentation expérimentale dont le grain de maïs était substitué par des niveaux de grade de 25U75WA dans les ingrédients alimentaires et les traitements étaient les suivants: 100m = 100% de grain de maïs, 66 m34c = 66% de grain de maïs de maïs plus 34% d'épis de maïs traité, 34m66c = 34% de maïs Grain Plus 66% COBS de maïs traité et 100c = 100% cobs de maïs traités dans un design carré latin 4 × 4 (4 animaux ont été tournés en 4 périodes pour tous les traitements). Traitement 34M66C avait une consommation de protéines brutes (CPB), une consommation de matière sèche (CMS), une consommation de matière organique (CMO) et une consommation de fibres de détergents neutres de 0,1334, 0,9500, 0,8921 et 0,4800 kg / j respectivement (p <0,05) tandis que le Digestibilité des protéines brutes (DPB), digestibilité de la matière sèche (DMS), digestibilité de la matière organique (DMO) et digestibilité de fibres de détergent neutres (DFDN) étaient de 79,57, 68,02, 66,26 et 57,8% respectivement (p <0,05). Tous les traitements avaient des analgésiques similaires (p> 0,05) Rumen NH3 allant de 23,55 à 24,00 mg / ml tandis que le pH de rumen était différent (p <0,05) et allait de 6,117 - 6,937Cependant, le traitement 100M avait un pH inférieur. Traitement 100m et 34m66C avaient un gain quotidien moyen (GQM) de 0,1150 et 0,1417 kg / j, respectivement (p <0,05), cependant, le traitement 100M avait un rapport de conversion d'alimentation inférieur (CAI) de 5,217 par rapport à 7,059 (p <0,05) pour 34 m66c. Il a été conclu que les agriculteurs comprennent 34 m66c dans le régime alimentaire des moutons de Tswana pour des performances optimales et réduisent également le coût des aliments pour animaux.

The burning of wood in industrial activities discharge a large amount of wood ash and affecting on the environment. The effects of neem (Azadirachta indica A. Juss.) wood ash on seedling growth of cowpea (Vigna unguiculata L. Walp.) was recorded. The data reveals significant (p<0.05) effects of neem ash on the shoot length and seedling length of cowpea with the increase in the concentration of neem wood ash treatment up to 20%. The results also showed the significant (p<0.05) decrease in leaf weight ratio of cowpea as the wood ash concentration increase in substrate as compared to without ash treatment (control). The effects of neem wood ash treatment on physical and chemical characteristics of soil including organic matter (%), pH of soil, calcium carbonate (%), chloride (meq/L), maximum water holding capacity (%) of soil, electrical conductivity (mS/cm), bulk density (g/cm3), sodium and potassium content (µg/g) content of soil was found. The wood ash produced changes in physical and chemical soil characteristic viz. organic matter (%), pH of soil, water content (%), calcium carbonate (%), chloride (meq/L), maximum water holding capacity (%), electrical conductivity (mS/cm), bulk density (g/cm3), sodium and potassium content (µg/g) content of soil. Wood ash treatment affected physical and chemical poperies of soil which in turn results decreased seedling growth performance of cow pea.

This study evaluated the possibility of using in natura Eucalyptus Wood Ash (EWA) from aviary furnaces as a mineral admixture in concrete. The ash was 100 mesh-sieved and added to the mix in 5, 10, 15 and 20% of the cement bulk. Physical analysis unveiled that EWA has a specific gravity higher than other organic originated residues, whereas its BET specific surface area is not enough to enhance its filler and/or pozzolanic effects. Chemically, the residue presented a low organic matter rate and a SAI below the minimum required by the Brazilian standards. EWA interfered in the times of cement set, increasing them, while FTIR unveiled mainly the presence of calcium carbonate bonds. The admixture compromised the concretes mechanical performance, leading to the conclusion that the sieving procedure of EWA alone is not enough do admit its usage as a mineral admixture.

Some medicinal plants have the tendency to manipulate the rumen microbial ecosystem, which in turn might reduce methane (CH4) emissions. The anti-methanogenic activities of leaf fraction of Piper betle, Aloe vera, Carica papaya, Azadirachta indica, Moringa oleifera, Tithonia diversifolia, Jatropha curcas and Moringa oleifera pods were studied at different doses. The plant materials were extracted with pure methanol and subsequently reconstituted at the rate of 25, 50, 75 and 100 mg in 1000 mL distilled water. Four mL of each plant extracts preparation was anaerobically incubated with 400 mg Eragrostis curvula hay in four replicates and the experiment was repeated five times. Plant extracts of P. betle and A. vera significantly increased total gas produced whereas other extracts recorded lesser or similar values to the control group. Leaf extracts of A. indica, C. papaya, J. curcas, M. oleifera, T. diversifolia and M. oleifera pods all significantly reduced CH4 volume at dosages of 25 and 50 mg/L due to the activities of their phytochemicals. Total volatile fatty acids and in vitro organic matter digestibility values recorded for all extracts were generally superior when compared with the control. Methane yield per unit of total gas were significantly lower in extracts of T. diversifolia, M. oleifera, A. indica, M. oleifera pods whereas it is higher in P. betle and A. vera. It can be concluded from the study that methanolic extracts of A. indica, C. papaya, J. curcas, M. oleifera, M. oleifera pods and T. diversifolia resulted in reduced CH4 production, and thus can be used potentially to manipulate rumen condition, improve feed digestibility and reduce enteric CH4 emission from ruminants. However, the in vitro results needs to be verified using in vivo studies by administering concentrated crude extracts at a rate of 25 mg or 50 mg per kg of roughage feed for small ruminants.

Surface waters are generally turbid because they contain suspended matter, organic matter, chemical and physical or even biological elements that make these waters unfit for drip irrigation. The almond powder of Moringa oleifera that was used in the study was dried in an oven for one month at temperatures of 25, 40 and 50°C and used to treat the water of Kongou Gorou Zarmagandey pond so it is suitable for localized irrigation. The purpose of this study was to evaluate the physico-bacteriological quality of the waters of this pond. The parameters studied are Escherichia. coli, faecal Streptococci, total germs and sulphito-reducers, organic matter, total residues and the color of treated water. After treatment of water with 100 mg/Lp Moringa oleifera seed powders dried at the respective temperatures of 25, 40 and 50°C, the supernatants were removed and analyzed. The results of this analysis show an increase in organic matter of 52.59, 55.84 and 57.14%; a slight reduction in total residues of 0.7%, 4.3% and 2.5% at the respective temperatures of 50, 40 and 25°C; an abatement of Escherichia. Coli is total (100% for all temperatures). For Streptococci, a reduction of 99.24% was observed for the dose at 25°C and 98.48% for those at 40 and 50°C. For Sulfo-reducing agents, the efficacy of the treatments is therefore total, 100% for doses of 100 mg. 1 to 25 and 40°C and about 99.99% for that at 50°C. Finally, in terms of color, there was a drop of 97.62%; 97.858% and 98.167% at the respective temperatures of 50°C, 25°C and 40°C. The analysis of the water in the study area shows that the latter is in line with the FAO guidelines on the physico-bacteriological aspects of irrigation water in general and that of drip irrigation in particular.
