Abstract The chemical composition of the herbage produced by
shrubs belonging to the genus Cytisus and allied genera
(Cytisophyllum, Chamaecytisus, and Genista sect. Teline)
was determined to appraise its potential value for forage. In their third year,
eight accessions were assessed in a semi-arid environment (400 mm annual
rainfall) for seasonal variation of leaf/stem ratio, and contents of ashes,
neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent
lignin (ADL), and crude protein (CP). Fibre and crude protein concentration
were similar to those of best-quality shrubby legumes like Medicago sp.
pl. Colutea sp. pl., or Chamaecytisus palmensis
(ADF, 18-35%; CP, 14-24%). Genista monspessulana had low fibre and high
protein contents, which were the most constant during the year. From the
results obtained in this and the previous agronomic study, Part 1 of this
series (González-Andrés & Ortiz 1996), Genista
monspessulana, Chamaecytisus podolicus, and C. supinus are
recommended as potentially useful forage shrubs because of their high dry
matter production potential, high survival rate, and favourable chemical
composition. This needs to be validated in studies involving animals.
