  2. Calliandra calothyrsus • Lokal : Kaliandra, Kaliandra Merah • Morphological description • Small, perennial, leguminous tree growing 2-12 m high.  Trunk diameter up to 30 cm. Leaves are bipinnate • Introduced into Indonesia in 1936 and from there to other parts of the tropics, notably east Africa, the area where it is now most widely used for fodder.

  3. Ecology Soil requirements Grows well on a wide range of soil types ranging from deep volcanic loams to more acidic metamorphic sandy clays.  Moisture Top In its native range, grows in annualrainfall regimes of 700-3,000 mm with 1-7 dry months.  Temperature Adapted to altitudes from 0-1,850 m asl .  Mean monthly maximum temperatures of 24-28ºC, and mean minimum temperatures of 18-24ºC.  Light Intolerant of heavy shade.  In Uganda and Tanzania it is being adopted in home garden systems where it is planted under banana with moderate shade. Uses/applicationsA multipurpose species grown primarily for forage as a supplement to low quality roughages for ruminant livestock.  Also used for the provision of green manure, shade for coffee and tea, land rehabilitation , erosion control.  Used as a pollen source for honey production and a host for the lac insect (Lacciferlacca) for shellac production.  It is also important in parts of Africa (e.g. Uganda, Rwanda) in providing stakes for climbing beans.An excellent fuelwood for cooking and small fires;  calliandra wood dries very quickly (overnight for small stems) and burns well with a smokeless fire

  4. Defoliation • Depends on use.  First cut 8-12 months after sowing.  For maximum leaf production, cut to a height of 0.5-1.0 m every 2-3 months.  • Normally cut for feeding as direct grazing by cattle, sheep and goats will normally result in high rates of plant mortality.  • Slashing calliandra to less than 30 cm above ground level and allowing ruminants to graze the regrowth can reduce plant mortality.  This limits the stripping of bark and cambium from the stem .  Calliandra is generally recommended for cut-and-carry feeding rather than for use in direct grazing systems.

  5. Feeding value • Nutritive value • Top • In vitrodigestibility of dried leaf from 19 provenances ranged from 24-47%.  reasonable animal production is achieved where calliandra has been adopted as a supplement to poor quality basal diets or as a partial replacement of concentrate feeds.  Good source of the vitamin carotene. • Palatability/acceptability • Freshly harvested leaves of calliandra are generally highly palatable to ruminants where animals have prior experience with the forage, although some problems with palatability have been reported from Mexico and Central America.  Provenances vary in palatability to some extent.  Palatability is significantly reduced when wilted or dried leaves are fed at high levels of supplementation. 

  6. Production potential • Dry matter • Produces DM yields of 3-14 t/ha/year, depending on climate and soil fertility.  • Animal production • Top • Generally used to improve the utilisation of low quality grasses or as a replacement for concentrate feeds.  In Zambia, goats fed a basal diet of poor quality hay lost weight at 20 g/day.  Weight gains of 24 g/day were achieved when supplemented with 140 g/day DM of calliandra leaf.  In Indonesia, sheep liveweight gains increased from 26 up to 52 g/day when supplementation levels of fresh calliandra leaf increased from 0-35% of total ration.  Cattle direct grazing calliandra over a 12-month period in Indonesia gained 0.33 kg/head/day . 3 kg of fresh calliandra leaf plus 2 kg of concentrate feed provided a similar response in milk yield and butterfat to 3 kg of concentrate feed.  • Not suitable as a feed for monogastric animals due to its high levels of astringent CTs.  Small amounts may be fed to chickens as leaf meal:  the carotene content gives a dark yellow yolk which can increase the market value of the eggs.

  7. Lokal : Sentro Morphological description (Description referring to the C. pubescensform as represented by cv. Belalto).Perennial, trailing-climbingherb with strong tendency to root at nodes of trailing stems.  Leaves trifoliolate, Uses/applications Grazed pastures in mixture with a grass, legume -only protein bank, cut-and-carry.  Potential also as soil cover. Centrosema pubescens

  9. Lokal : GAMAL Uses/applications Living fences/hedges, cut and carry feed for ruminants, alley farming, protein banks, green manure , support, shade, honey, rodenticide, medicinal, firewood, pigmentation of eggs. Gliricidia sepium

  10. Feeding valueNutritive valueTopHigh nutritive value.  Crude protein content 18-30% and in vitro digestibility of 60-65%.  With the exception of palatability , variability in nutritive quality among provenances has not been assessed.Palatability/acceptabilitySome palatability problems occur with ruminants depending on prior experience.  Naïve animals seem to refuse leaves on the basis of smell, often rejecting them without tasting, suggesting that the problem lies with volatile compounds released from the leaf surface.  However, no palatability problems are reported in Indonesia, Sri Lanka, Colombia or Guatemala where successive generations of ruminants have been fed gliricidia.  Wilting leaves for 12-24 hours before feeding increases intake.  Prior experience is the most important attribute of palatability , so that local landraces are most preferred.  While naïve animals are used, provenances from Mexico tend to be less palatable compared to those from Costa Rica and Colombia.

  11. Production potential • Dry matter • Annual leaf DM production varies from 2-20 t/ha/year, depending on a wide range of factors.  In fodder plots, annual yields of 5-16 t/ha of leaf DM, or up to 43 t/ha fresh leaves have been obtained.  In Nigeria, gliricidiahedgerowsinterplanted with 4 rows of Panicum grasses yielded 20 t/ha/year of total DM (grass and gliricidia). • Animal production • Top • Gliricidia is normally used as a green forage, protein supplement to low-quality tropical forages and by-products for cattle, sheep and goats.  It may be used as the sole feed in the dry season.  Feeding levels have been 1-3% of body weight for cattle and goats, indicating a supplementation level of 30-100%, although a 20-40% level is more common.  Increases in liveweight gains of approximately 25% have been reported for steers grazing gliricidia-grass pastures, compared with steers grazing grass alone.  Results from experiments with dairy cows and buffaloes reported similar or slightly increased milk yield and milk fat yield when concentrates were replaced by gliricidiaforage up to about 25% of intake.The effects of gliricidiaforage on reproducing ruminants have been variable.  In one trial, ewes supplemented with gliricidia produced a higher lamb crop, better lamb weights and had reduced ewe weight loss compared with those not fed gliricidia.  In an unrelated trial, lambing results were poorer when gliricidia was fed, due to lower feed intake, possibly as a result of insufficient adaptation to the forage .Laying chickens fed sun-cured gliricidia at 4.5% of total diet gave good egg production, egg weight and yolk colour.  Yellow yolk colour can be achieved by feeding milled leaves at 2-4% of the ration.  Diets containing up to 10% gliricidia can be fed to growing chicks without affecting performance and survival, but higher rates may have anti-nutritive effects.

  12. Lokal = Turi, Toroy, Tuwi Uses/applications Valued as a fodder throughout Indonesia, particularly for dry season feeding of cattle and goats.  Commonly grown on paddy bunds, and around gardens or cropping fields for its nitrogen contribution.  The sparse canopy of S. grandifloracasts relatively little shade, hence its suitability close to sun-loving crops and gardens.  S. grandifloragrows fast enough to be used as an annualgreen manure crop.  The leaves, seed pods and flowers are used as human food in southeast Asia.The light density wood of S. grandifloramakes poor firewood and is not durable as a timber, however it can be used for low quality pulp.  Poles are used for light construction but have limited durability.  Used as a shade crop and as a support for climbing crops.  Also used as a component of windbreaks. Sesbania grandiflora

  13. Feeding valueNutritive valueTopContains 25-30% crude protein.  Supplementation with S. grandifloraof goats fed guinea grasshay increased intake by 25% and supported a positive N balance.  In saccodigestibility was 75% in 12 hours.Other in vitroand in saccostudies report the very high forage quality of S. grandiflora.Palatability/acceptabilityHighly palatable to ruminant livestock.  Also generally well accepted by monogastrics.

  14. Production potential • Dry matter • An annual yield of 27 kg of green leaf/tree was achieved by harvesting side branches A green manure yield of 55 t/ha green material in 6.5 months was achieved in Java.  Wood yields of 20-25 m³/ha/year are achieved in commercial plantations in Indonesia. • Animal production • Top • No long-term animal production studies have been reported, but S. grandiflorais a major component of ruminant diets in eastern Indonesia where it may comprise up to 70% of total forage allowance during the dry season.  Anecdotal reports of high liveweight gains in cattle are common.  In India, milk yield was increased by 8% (9.2-9.9 l/day) when cattle were fed 5 kg fresh leaf/day.In Western Samoa, goats failed to gain weight when supplemented with S. grandiflora, although the reasons for this poor result were not identified.  The authors suggested that supplementation with S. grandiflorashould be limited to 30% of total feed on the basis of this experiment.Poor weight gains in chickens has led to the recommendation that supplementation of poultry feeds with S. grandiflorashould be limited to 2% of total ration.

  15. Lokal : Lamtoro Feeding value Nutritive value Top L. leucocephalafoliage is noted for its very high nutritive value for ruminant production.  Typical values for the edible fraction are 55-70% digestibility, 3-4.5% N, 6% ether extract, 6-10% ash, 30-50% N-free extract, 0.8-1.9% Ca and 0.23-0.27% P.  Na levels are generally below requirements for ruminants at 0.01-0.05%.  Leaves also contain 2-6% condensed tannins (CT), phenolic compounds which bind and protect dietary protein from degradation in the rumen .  Providing that the protein-CT complexes dissociate post-ruminally allowing N absorption in the lower gut, CTs have the potential to increase protein uptake. Palatability/acceptability L. leucocephalais highly palatable to most grazing animals, especially compared to other foragetree legumes such as Calliandracalothyrsusand Gliricidiasepium. Leucaena leucocephala

  16. Production potential • Dry matter • Yields of forage vary with soil fertility, rainfall, altitude, density and cutting frequency from 1-15 t/ha/year.  Leaf yield is maximised by cutting at 6-12 week intervals during the growing season .  Yields in extensive hedgerow plantings in the dry tropics and subtropics generally range from 2-6 t/ha/year.Very high yields (>15 t/ha/year) in southeast Asia and Hawaii, with plants 0.5-1.0 m apart in rows 1-3 m apart.Fuelwood yields compare favourably with the best tropical trees, with height increments of 3-5 m/year and wood increments of 20-60 m³/ha/year for arboreal varieties. • Animal production • Top • Excellent growth rates of 1.26 kg/head/day for cattle grazing leucaena-buffelgrass (Cenchrusciliaris) pastures over a 6-month period were reported in Queensland, Australia, although growth rates are more commonly 250-300 kg/head/year (0.7-0.85 kg/head/day).  Under irrigation in northwestern Australia, annualliveweight gains of up to 1,700 kg/ha/year have been recorded for cattle grazing at 6 head/ha.
