Abstract From 1999 to 2000 four leguminous
shrub species
endemic from the Canary Islands (Spain): Chamaecytisus palmensis
(tagasaste), Teline canariensis, Teline osyrioides sericea
and Teline osyrioides osyrioides were studied as a source of
animal forage in two different experiments. One experiment was carried
out on a crop planted at a density of 5142 shrubs/ha, located in La
Laguna (Tenerife, Spain) at 550 m a.s.l., with an annual rainfall
between 338 and 562 mm. The other experiment was carried out on
self-sown populations of the same species in their natural habitat on
Tenerife Island. Seasonal variation of the concentrations of P, K, Ca,
Mg, Na, Mn, Zn and Cu were studied in the edible dry matter of the four
cultivated populations; cuts were made at the end of each season. The
shrubs studied had adequate levels of K, Ca, Na and Zn for good animal
nutrition. Mg levels were adequate in only Chamaecytisus palmensis.
Mn levels were adequate in all populations except for the cultivated
population of Teline osyrioides sericea. Phosphorus levels
fulfilled the animals’ requirements in autumn and winter in only Chamaecytisus
palmensis. All the cultivated species had Cu levels too low to
fulfil the animals’ requirements.
