Soaking pods with polytethylene glycol (PEG) was shown to increase significantly in vitro gas production and 95-h organic matter degradability (from 69 to 79%) but this treatment is too costly for smallholder farmers (Mlambo et al., 2001). It was ensured that the chestnut extract tanning content was kept at 75%; hence, the tannin concentration in Trial 2 and Trial 3 was at 0.75 and 2.7 wt%, respectively. The Rangland Journal, 17 (2): 213-227, Barbind, R. P. ; Waghmare, P. S. ; Patel, P. M., 1994. Alhaji, M. H., Sanaullah, K., Lim, S. F., Rigit, A. R. H., Hamza, A., and Khan, A. It is thickly spherical in shape with its stems and branches blackly colored. In Senegal, the bark, leaves and young pods are chewed as an antiscorbutic. The extraction reaction was batch-wise and the moisture contained in the pod was measured, and it represented the amount of water used for the extraction. Feed intake and dietary preferences of sheep and goats offered hay and legume-tree pods in South Africa. Reproduction is entirely sexual. In general, vegetable tannins, such as those extracted from A. nilotica pods or E. globulus bark, provide a high environmental resistance when used in the tanning of leather (Pinto et al. Nutritive evaluation of some browse tree legume foliages native to semi-arid areas in western tanzania. Melone, F., Saladino, R., Lange, H., and Crestini, C. (2013). Which is contain considerable amount of tannins whereas the grand powder of Acacia nilotica pods contain23% in Sudan and 16% in India . Blair Rains, A., 1963.

Specifically, tannins are used for the clarification of antimicrobial activity in beverages as well as conversion of hides and skin into leather (Silvestre and Gandini 2008). Results of physical tests obtained after the retanning of leather with chromium tannin (Trial 1), chestnut extracts at 1% (Trial 2), chestnut extracts at 3% (Trial 3), and A. nilotica tannin extracts (Trial 4). The dimensionless coded values of the independent variables were obtained using Eq. The method was simple, reliable, and easily applicable. “Total phenolic contents and antioxidant capacities of selected Chinese medicinal plants,” International Journal of Molecular Sciences 11(6), 2362-2372.

These greyish-green pods are covered in tiny soft hairs (i.e. The coefficients of determinations were 0.9750 for extraction yield, 0.9626 for TPC, and 0.9774 for AA, which indicated that the model equations obtained fitted the experimental data. The obtained experimental and predicted values are depicted in Table 2 for extraction yield, TPC, and AA. It is widely used in ethno-medicine (Orwa et al., 2009; Cook et al., 2005; Fagg et al., 2005). The fruits are linear, flattened, narrow indehiscent pods, 4-22 cm long and 1-2 cm broad, dark-brown to grey in colour and glabrous or velvety. The composition of these materials, and particularly their amount of fibre and tannins, is quite variable. Dairy Sci., 35 (4): 613-615, Patel, B. M., 1966. Bark[?] The first group (nilotica, tomentosa, cupressiformis, indica) consists of tall riverine trees that grow in seasonally flooded areas. The temperature and time as well as liquid recirculation ratio for different methanol/water solvents were determined for the ground pod after the extraction. The flowers on the acacia nilotica tree grown in the summer season and the pods start arriving at the beginning of the autumn season. However, while the pods supply protein and energy, their high tannin content is detrimental to their digestibility, degradability and palatability (Ngwa et al., 2002; Mlambo et al., 2008, Rubanza et al., 2003a). The resulting mixture obtained was allowed to stand for 5 min at 50 °C, and its UV-visible absorbance was measured with a spectrophotometer (UV-2501PC; Shimadzu, Mumbai, India) at 790 nm. Babul (Acacia nilotica). It also contains about 52% of calcium and 20% of magnesium. DOI: 10.1016/S0308-8146(00)00223-5, Nasr, A. I., Mueller, H., Abdelsalam, M. M., Azzam, A. H., Jungandreas, C., Poppitz, W. (2017). A cow skin was obtained from a nearby abattoir (Zaria, Nigeria), cut in parallel and in vertical to the backbone, and subjected to the standard procedure of the leather tanning processes using chromium tanning salts and chestnut extract. The statistical significance of the mean square ratio was obtained using ANOVA. & Thonn., Mimosa arabica Lam., Mimosa nilotica L., Mimosa scorpioides L., Vachellia nilotica (L.) P.J.H.

It also showed the surface profile that helped in the precise and accurate determination of the optimum point. The three model equations obtained were verified at the 95% confidence level, and the values for the “lack of fit” (prob. (2008) for the extraction E. globulus bark extract using NaOH, was higher. It should be noted that the measurement and nutritional interpretation of phenolics and tannins content in Acacia species are particularly difficult (Mlambo et al., 2008). Young female goats were fed almost exclusively with fallen inflorescences at the end of the flowering period (Audru et al., 1993). $23.95. Acacia nilotica originated from Africa, the Arabian peninsula and the Indian subcontinent (USDA, 2012). Under the same boundary conditions for extraction yield (Figs. Method : Spread 1 to 1.5 metres of coarse cloth is evenly, with its corners secured. The causticity of the tannin extracts is related to the attainment of lower mechanical resistance, as well as lower elongation at break (Pinto et al. The extracted tannins were characterized according to the TAPPI T652m-89 (1989) standard to determine the amount of non-volatile solids. All parts of the plant contain high levels of tannins that may hamper protein digestibility and animal performance (Carter, 1994). Therefore, there was an adequate signal for the models to be used to traverse the design space. y=-3, n=0: n: 1.02: Has the species become naturalized where grown? Model prediction and actual values of the three response variables: (a) extraction yield, (b) total phenolic content, and (c) anti-oxidant activity. Sci. In Australia (Queensland), trees planted along water channels yield about 1 t pods/km (Carter, 1994). Feedipedia, a programme by INRAE, CIRAD, AFZ and FAO. Description Acacia nilotica (=Vachellia nilotica) is a hardy, semi-deciduous, small to medium-sized, mushroom shaped tree with dark blackish-brown, fissured bark when mature and a dense crown.This fissured bark is home to many invertebrates and therefore attracts Woodpeckers and other insectivorous birds. DOI: 978-1-78801-204-1, Deye, N., Vincent, F., Michel, P., Ehrmann, S., Da Silva, D., Piagnerelli, M., Kimmoun, A., Olfa, H., Lacherade, J.-C., De Jonghe, B., et al. Similar conditions also led to the attainment of 50.7 wt% TPC and 51.3 mmol AAE/100 g pod. Vachellia nilotica is an evergreen Tree growing to 10 m (32ft) by 12 m (39ft) at a fast rate. Agroforestry Systems, 57 (1): 29-37. The voucher specimens are deposited in the Botany Department herbarium, Aswan Faculty of Science, Egypt. 2003). However, the amount of tannins can be extremely important, both in the leaves (up to 25% total extractable tannins and 5% condensed tannins (Rubanza et al., 2005), and in the pods, where the content in soluble phenolics is particularly high. Res., 28 (1): 31-37, Shaltout, K. H. ; El-Keblawy, A. The effect of the crosslinking is also to enhance the thermodynamic stability of the formed bond as a result of the changes to the macromolecules in the tanned hide and skin. These authors extracted tannins form different part of the acacia species and it was found that a mature pod has the highest percentage of tannins (22.2%) as compared to the bark and leaves (11.8% and 10.5%, respectively) of the same acacia species. In West Africa, the pods and leaves are considered to have anthelminthic properties on small ruminants and this has been confirmed by in vitro experiments on nematodes. (2007), in which the TPC and AA contents of the grape extracts were higher at the lower temperature. A total of 1% and 3% chrome extract were used for assay1 and assay2 and it contained 75% of tannins extract. The maximum extraction yield of 46.2 wt% (pod extract) was achieved at 200 min, 85 °C, and 40% methanol concentration. 2. Willd., Acacia arabica var. Dept. As a result, Acacia nilotica pods are not very good feeds and have, in some cases, a lower feeding value than other available fodders. Acacia nilotica pods were found to be able to meet the maintenance requirements of sheep but they were of low digestibility and phosphorus supplementation was required (Chellapandian et al., 2003). Trop. A constant heating rate of 3 °C/min was continually used during the heat-up period until the required temperature was reached; once this was achieved, the contact time was measured using a stopwatch. 1; the dependent variables (Yn) were the total extraction yield (YEE), TPC (YTPC), and AA (YAA) present in the extracted tannin. The crown may be flattened or rounded. 2015). Genetic variability analysis of the polyploid complex of, Ngwa, A. T. ; Nsahlai, I. V. ; Bonsi, M. L. K., 2002. Pods can be eaten on the ground or browsed by livestock or collected to be fed on the farm. PEST RATING PROFILE Initiating Event: Vachellia (Acacia) nilotica is a federal noxious weed and is one of the 20 worst weeds in Australia because of its invasiveness, potential to spread, economic and environmental impacts. Incidences of lethal poisoning, probably due to tannins, when goats consumed excess Acacia nilotica pods, were reported in South Africa. tormentosa describes how the foliage, flowers and pods are used by Afar communities to feed sheep, goats and camels (Audru et al., 1993). The forage management of Acacia nilotica can be quite complex as various parts of the plants are used at different periods of the year for different types of animals. The adjusted R2 values were 0.9500, 0.9252, and 0.9549 for extraction efficiency, TPC, and AA, respectively, and the values were close to the corresponding values for the R2 (0.9750, 0.9626, and 0.9774, respectively); this indicated that the experimental data were reliably utilized in the determination of the response models.
