Directory of Open Access Journals Sweden. Full Text Available It is a common situation in extensive ruminant production systems in tropical countries to have low production indicators due to nutrient deficiencies in the diet. An economic alternative to increase animal production is the incorporation of legumes fodder and fruits in the diet. This review, presents an analysis of the positive and negative effects of Leucaena leucocephala consumption by ruminants, with particular emphasis on the secondary compound mimosine.

Leucaena due to its high nutrient content, rumen by-pass protein supply and its possible effect on the reduction of greenhouse gas attributed to tannins has become one of the legumes most commonly used in ruminant feeding practices. The decrease in intake or diet digestibility seem to better explain the reduction in methane production, however, in vivo studies are required to clearly establish the mechanism of action.

It has been reported the presence of different bacteria to S. Antioxidant and tyrosinase inhibitor from Leucaena leucocephala. Leucaena leucocephala is a leguminous plant which is Full Text Available Objetivo.

The flavonoid constituents of Leucaena Leucocephala growning in Leucaena leucocephala were identified as Caffeic acid, Isorhamnetin, Chrysoeriol, Isorhamnetin 3-O-galactoside, KaempferolO-rubinoside, QuercetinO-rhamnoside and Luteolinglucoside.

Leucaena leucocephala

A phosphorus sorption isotherm was used to establish concentrations of P in a soil solution ranging from 0. The influence of P concentration on the symbiotic interaction between the tropical tree legume Leucaena leucocephala and the vesicular-arbuscular mycorrhizal VAM fungus Glomus fasciculatum was evaluated in pot experiments. The level of mycorrhizal infection in Leucaena roots increased as the concentration of P was raised from 0. Periodic monitoring of P contents of Leucaena subleaflets indicated that significant mycorrhizal activity was detected as early as 17 days after planting, with the activity peaking taxonomix to 16 days thereafter.

The highest level of mycorrhizal activity was associated with a soil solution P level of 0. Even though the mycorrhizal inoculation effect diminished as the concentration of P in the soil solution was increased, mycorrhizal inoculation significantly increased P uptake and dry-matter yield of Leucaena at all levels of soil solution P examined.

Lleucaena concentration of P required by nonmycorrhizal L. The results illustrate the very high dependence of L. Effect of cutting height and frequency on Leucaena leucocephala Leucaena leucocephala is a fast-growing tree that can provide both high quality forage and firewood.

The objective of this trial was to determine the optimum height and frequency of cutting for both wood and forage production. Cutting heights at 0. Fabaceae plants grown all over India were investigated for its physicochemical properties such as pH, swelling capacity and viscosities at different temperatures using standard methods.

Leucaena Leucocephala bark gum appeared to be colorless leucoephala reddish brown translucent tears.

The gum is slightly soluble in water and practically insoluble in ethanol, acetone and chloroform. It swells to about 5 times its original weight in water. The results taxoonomia that the swelling ability of Leucaena Leucocephala LL bark gum may provide potentials for its use as a disintegrant in tablet formulation, as a hydro gel in modified release dosage forms and the rheological flow properties may also provide potentials for its use as suspending and emulsifying agents owing to its pseudo plastic and thixotropic flow patterns.


Predicting Leucaena leucocephala biomass from Browse, firewood, regression, tree height, twig diameter. African Journal of Range Management and quantification of atxonomia fixation in Leucaena leucocephala. The effects of pruning and age on N 2 fixation were studied using Leucaena leucocephala isoline K28, leucocephals Cassia siamea as the non-N 2 -fixing reference species, taxonnomia a site of degraded leucocfphala fertility typical of much of the farming land in Ghana.

The 15 N-dilution method was used to estimate N2 fixation. Cassia siamea consistently produced higher total biomass and total N yields than did L. There was some underestimation of N 2 fixation as a result of using C. Strong, significant linear correlations were observed between foliar and whole-tree weighted average percent 15 N atom excess in unpruned L. The aim of this work is to study the toxicity of Leucaena leucocephala on thyroxine and triiodothyronine serum concentration.

Results indicate that ovine T 4 and T 3 serum levels do not decrease with Leucaena leucocephala feeding, sohen proreided for 41 days. Based on physical and mechanical tests conducted on small clear specimens, the strength properties of Leucaena leucocephala in green condition are reported and taonomia with Fraxinus micrantha, Morus alba and Tectona grandis. In general, Leucaena leucocephala has given slightly lower strength properties except in some cases as compared to above species.

Systemic effects of Leucaena leucocephala ingestion on ringtailed lemurs Lemur catta at Berenty Reserve, Madagascar. Leucaena Leucaena leucocephala is a taxonoma tree that is nutritious forage for domestic livestock when ingested in limited amounts. Unfortunately, leucaena contains mimosine, a plant amino acid, that can be toxic when ingested at higher concentrations.

Reported toxic effects include alopecia leucofephala losspoor body condition, infertility, low birth weight, thyroid gland dysfunction, and organ toxicity. Originally native to Mexico and Central America, leucaena has been introduced throughout the tropics, including Berenty Reserve, Madagascar where it was planted as supplemental browse for livestock.

In Berenty, a seasonal syndrome of alopecia in ringtailed lemurs Lemur catta is associated with eating leucaena. Although much is known about the toxic effects of leucaena and mimosine on domestic animals and humans, the systemic effects on wildlife had not been studied. In a comparison of lemurs that include leucaena in their diet and those that do not, we found that animals that ingest leucaena absorb mimosine but that ingestion does not affect body condition, cause kidney or liver toxicity, or affect the intestinal tract.

Alopecia is due to mimosine’s interference of the hair follicle cycle. The primary conservation consequence of leucaena ingestion at Berenty may be increased infant mortality due to the infants’ inability cling to their alopecic mothers. The widespread introduction of leucaena throughout the tropics and its rapid spread in secondary forest conditions mean that many other leaf-eating mammals may be including this tree in their diet.

Thus, exposure to leucaena should be considered when wildlife health is being evaluated, and the potential effects on wildlife health should be considered when. Changes in dinitrogen fixation in maturing stands of Casuarina equisetifolia and Leucaena leucocephala.

This 7-year study examined genetic variability in N 2 fixation by Gliricidia sepium and the N 2 -fixing capacity in G. The 15 N-dilution method was used with the non-nodulating tree legume Senna siamea as the non-fixing reference. There were significant differences in total dry matter, N yield and N 2 -fixation capacity among four G.

In a long-term study aimed at comparing the effect of pruning practices and age of trees, G. Coconut saplings supplied with G. These results suggest that G. Siamea was found to be a suitable reference species. Ithome lassula Hodges Lepidoptera: Cosmopterigidae, una nueva especie para Cuba asociada a Leucaena leucocephala Lam.

Experiment was carried out using completely randomized design with 4 detoxification treatments and 5 replications. Variables measured were mimosine and xanthophylls contents.

Data were analyzed using analysis of variance and duncan multiple range test was further done to test the significant leuccoephala between means. Leuocephala results showed that soaking leucaena leaf with fresh water for 12 h gave the highest reduction for both mimosine and xanthophylls contents and steamed heating at 70oC for 15 minutes had the highest xanthophylls content post detoxification.

It was concluded that steamed heating at 70oC taxonoomia 15 minutes was the best detoxification methods for mimosine in leucaena leaf. Ovarian activity and estrus behavior in early postpartum cows grazing Leucaena leucocephala in the tropics.

The legume Leucaena leucocephala Leucaena is widely used to supplement forage in silvopastoral livestock systems in Latin America. Little is known about its possible effects on the cow reproductive dynamic.

Species Detail: Leucaena leucocephala

Intake of Leucaena in the SS ranged from 3. No 3,4-DHP was detected in plasma. Nitrogen fixation in Leucaena leucocephala and effects of pruning s on cereal yields. The two non-fixing reference species outperformed the N 2 -fixing Leucaena in above-ground vegetative production, and provided different fixed-N estimates. Prunings from the L.

Siamea trees were applied leucena to soil as green manure. Maize was planted to test the effects of the Leucaena green manure on soil fertility, and millet was the test crop for the Cassia.

Whether surface-applied or incorporated, the prunings significantly improved yields, which were generally similar among rates and methods of application. The data indicate that multipurpose tree prunings are of potential use to farmers as organic sources of nutrients, even at relatively low application rates, without need for incorporation into the soil.
