Nutritive quality of native species from Canary Islands (Spain) with forage value for dry areas
The chemical-bromatological quality of five native species from Lanzarote (Canary Islands, Spain) was investigated. Sixteen natural populations all around the island were studied. Both the edaphic and climatic features of sampled zones were observed. The following species were studied: Atriplex halimus, Bituminaria bituminosa, Echium decaisnei, Coronilla viminalis and Lotus lancerottensis. Five plants for each specie and population were randomly selected (with three repetitions) except for B. bituminosa (four plants). Three samplings of vegetal material were carried out (Spring/2008, Summer/2008 and Winter/2009) and one soil sampling. During the studied period (2008-2009) a mean air temperature of 20.6°C and an average rainfall of 120 mm were measured. The obtained results show alkaline soils (pH 8.2-8.5) with low contents of organic matter (0.27-1.47%) and electric conductivity between 0.65 and 1.9 dS.m-1. Atriplex halimus and E. decaisnei showed interest due to the high ash content (32.7% and 25, 8% respectively). All the species present appropriate mineral contents of P (0.15- 0.21%), K (0.37-2.10%), Ca (0.37-0.61%), Na (0.08-0.36%) and Mg (0.15-0.39%) for forage use. The mean values of neutral detergent fibre (NDF) and acid detergent fibre (ADF) in L. lancerottensis specie (46.6% and 39.5% respectively) were considerably higher than in the other species. A high mean protein content was obtained in C. viminalis (15.6%) while in the other species it varies from 8.8% and 13.9%. These results indicated that the studied species are suitable to be growth and used as forage.
