Boivin [ Fabaceae ]. Boivin is a tropical tree from the dry areas of East Africa and India, used as fodder for livestock. Albizia amarra is a small to medium-sized, deciduous, acacia-like tree, 3- m high. It is many-branched and forms a wide, dense and rounded crown. The root system is shallow and spreading Orwa et al.
Young shoots, branchlets and leaves are pubescent. Leaves are paripinnate, cm long, bearing pairs of pinnulae with about pairs of leaflets. The leaflets are minute, about mm x 0. The flowers are white, cream, or pinkish-white in colour, and fragrant. They are grouped in showy globulous clusters, 2.
During flowering, the trees resemble cherry trees in blossom FAO, Fruits are indehiscent, flat, straight pods. They are cm long and 2. They contain compressed, amada, hard-coated, brown seeds IBP, ; Orwa et al. Albizia amara is a multipurpose tree of which many parts are used. The wood is hard, fine grained and strong. It is used for construction, agricultural implements, and furniture.
It is a good firewood that can be directly burnt or made into charcoal. The fruit is inedible and the seeds are alleged to be poisonous.
Leaves are sometimes used as an adulterant for tea. They can be dried and ground to make soap and shampoo IBP, ; Orwa et al.
Albizia amara provides a wide range of environmental services: It is a source of nectar for bees and is used in urban areas as an ornamental tree Orwa et al. The leaves are used as fodder for cattle, sheep and goats, though they are less palatable than other forages Orwa et al.
In ethnoveterinary medicine, preparations of leaves in mixture albixia other foliages are used to cure mastitis, and mites and ticks infestations in cows Reddy, Albizia amara is found in deciduous acacia forests from foothills at m and up to an altitude of m.
It does better in well-drained light soils but can also grow on clays along river banks where it can get more moisture. However, Albizia amara is very hardy and highly tolerant of drought. It grows in places where annual rainfall is between and mm but tolerates as little as mm. Albizia amara requires full sunlight and is intolerant of shade IBP, ; Orwa et al. Albizia amara can readily reproduce from coppices.
The seeds can also be sown on field borders. They should be soaked in boiling water prior to planting IBP, Albizia amara is a slow growing species that has poor competitiveness. It can be used in agroforestry systems. In India, Indonesia and other countries of South-East Asia, it is intercropped with maize, cassava and trees like papaya, mango or orange.
The trees can be lopped for the provision of forage in cut-and-carry systems, or they could be browsed by sheep and goats without hampering trees survival Rai et al. Albizia amara sheds its leaves for months during winter. Albizia amara is an N-fixing tree and its spreading root system helps binding the soil.

Albizia amara leaves have a high protein content but also high NDF and lignin contents which limit their digestibility. During the dry period, the protein content decreases and the lignin content increases Berhane et al. The very high lignin content must be stressed: The leaves are relatively low in calcium and phosphorus compared to other browse species Berhane et al.
Albizia amara is browsed by domestic ruminants amarra cattle, sheep, goats and camels Aregawi et al. Albizia amara leaves can be browsed or cut for use in cut-and-carry systems. The leaves, though not very palatable, are eaten from lopped or browsed branches when better liked browse is not available Rai et al.
However, the individual effect of albizia leaves was not assessed Rai et al.
In vitro gas production from leaves was low the lowest of 20 species assessed in Ethiopiasuggesting low digestible and metabolizable energy contents for ruminants Ondiek et al. The mature pods are eaten by game and stock but were reported to cause digestive problems Aregawi et al. No publications seem available in the international literature on the use of Albizia amara leaves in domestic rabbit feeding October However, the leaves of Albizia amara are eaten by many species of animals, including macaques Krishnamani,and are probably a potential source of forage for rabbit feeding.
Nevertheless, some direct studies would be useful. It could be a moderate source of energy with a calculated content of digestible energy of about 8.
The lignin content of albizia is valuable for rabbit feeding because of the high level of lignin recommended for weaned rabbits more than 5.
