“…Tannin compounds contained in the extract can reduce peristalsis and intestinal secretions [20]. In addition, flavonoids are also known to inhibit gastrointestinal motility and electrolyte secretion [14], [21].…”

“…Tannin compounds are as astringent, tannin works as astringent by wrinkling the surface of the small intestinal mucosa and stimulating water absorption in the lumen. This condition can ultimately reduce diarrhea [14]. This study was constructed and aimed to investigate the ethanol extract of L. leucocephala seeds as antidiarrheal using two different methods; these include castor oilinduced diarrhea and intestinal transit methods.…”

BACKGROUND: Leucaena leucocephala belongs to the Leguminosae/Fabaceae family. L. leucocephala seeds contain alkaloids, flavonoids, and tannins which according to the previous research have antidiarrhea activity. AIM: This study was investigate the antidiarrheal activity of the ethanol extracts of Leucaena leucocephala (Lam) de Wit seeds induced by oleum ricini and intestinal transit methods for rats. MATERIALS AND METHODS: L. leucocephala seeds were extracted by maceration with 80% ethanol. Evaluation of antidiarrheal extract activity was performed by induction of oleum ricini and intestinal transit methods. The extract at dose doses of 50, 100, 200, and 400 mg/kg BW was orally administered to the animals 1 h after induction by oleum ricini. Then diarrhea time, frequency, consistency, stool weight, and duration of diarrhea were observed every 30 min for 6 h. In determining the intestinal transit method, a percentage of the distance of the Chinese ink determined. This study was used positive control as Loperamide (1 mg/kg BW) and 0.5% Na-CMC as a negative control. RESULT: In diarrhea induced by castor oil, L. leucocephala seed extract at doses of 100, 200, and 400 mg/kg bw has been shown to significantly delay the onset of diarrhea, reduce diarrhea frequency, stool weight and duration of diarrhea compared with Na CMC as a negative control (p < 0.05). The extract at a dose of 400 mg/kg bw did not differ significantly from loperamide as positive control (p > 0.05). In this study, L. leucocephala extract reduced the distance traveled by Chinese ink in the intestine but only at a dose of 400 mg/kg bw which has a comparable activity with loperamide significantly . The antidiarrheal activity of extract showed at a dose dependent manner. CONCLUSION: The ethanol extract of L. leucocephala seeds has antidiarrheal activity which supports its use in folk medicines.

“…At 5-9%, it inhibits the activity of bacteria and anaerobic fungi and reduces feed intake (Akin andRigsby, 1985, Leng 1997). Above 9% tannins may become lethal to an animal dependent on no other feed (Kumar, 1983). However, a little tannin above the tolerant level has been usually accepted to protect protein of forages and allow a higher efficiency of feed utilization by the animal (Idahor 2006).…”

Low pasture quality and quantity adversely affect the performance of ruminants in the tropics. This necessitated the search for other feed resources that could augment the deficit, particularly, in the dry season. However, some of these feed resources contain phytochemicals which if not properly processed could be detrimental to ruminants. This study was carried out to determine the effects of processing on nutrients, phytochemicals and microbial characteristics of WAD sheep fed processed Gmelina arborea leaf based diets. Gmelina arborea leaves (GAL) were harvested and used as fresh, chopped, sun-dried, air-dried and boiled-dried. Nutrients and phytochemicals were determined from samples. Rations were comprised in the following proportions; T1 (50% Penniseum purpureurn: 50% fresh Gmelina arborea leaves), T2 (40% Penniseum purpureurn: 60% chopped Gmelina arborea leaves), T3 (40% Penniseum purpureurn: 60% air dried Gmelina arborea leaves), T4 (40% Penniseum purpureurn : 60% sun dried Gmelina arborea leaves), T5 (40% Penniseum purpureurn : 60% boil dried Gmelina arborea leaves). were randomly assigned to one of the rations with eight sheep per group in a completely randomized design. Ninety days post-feeding, rumen liquor was collected for microbial assay using standard procedure. The CP and calcium were increased in T1 and T2 compared to others except for NFE which was reduced. Tannin and saponin increased in T1 and T2 but reduced in T5. Streptococcus spp was absent in T5 compared to T1 and T2. Lower total bacteria count was observed in T5 compared to other treatments. Boiled-drying reduced the crude protein and phytochemicals contents of Gmelina arborea leaves with reduction in total bacteria count in the rumen.

“…A study on the analysis of the leaves of Acacia nilotica, P. cineraria and Zizyphus nummularia (Kumar 1983) showed that the percentage crude protein (CP) digestibilities were 74.7, 32.8 and 53.5% respectively and they seemed to be inversely related to the percentage protein precipitating capacities in tannic acid equivalents. It has also been reported that leaves of P. cineraria contain less crude fibre content and more calcium and nitrogen-free extract compared to leaves of green oats (Avena sativa) (Kundu and Sharma 1988).…”

This paper reviews the information available mainly on the fodder aspects of two of the important fodder tree species of Indian arid regions viz. Prosopis cineraria and Ailanthus excelsa. The fodder of both have ready markets and trees of both species are lopped heavily in the arid areas of Rajasthan, India. Whereas P. cineraria is useful for both green and dry fodder, A. excelsa is more popular for its green fodder. Complete lopping in winter produces more fodder yield in P. cineraria. The practice of annual lopping of P. cineraria needs to be investigated in detail. Trees of this species also help in improving soil properties. Both species are economic for growing in farm fields. Major pest attacks reducing fodder yield are not common in either species.
