Abstract
This study evaluated the plants of the Caatinga
(seasonal dry forest) used as forage in rural communities in
northeastern Brazil by comparing the known nutritional composition of
species with the nutritional attributes described by the local people.
Key informants were selected using the snowball technique, and these
informants used their local knowledge to characterize 30 species
according to their nutritional attributes and local preferences
regarding their use. The nutritional composition of all of the
previously described species was favorable for ruminant diets, but for
some species (22), there were no prior records of their nutritional or
anti-nutritional properties. The most culturally salient species
included Waltheria rotundifolia Schrank, Merremia aegyptia (L) Urb.,
Croton blanchetianus Baill., Spondias tuberosa Arruda and Tragus
berteronianus Schult. The salience values (local importance) were
significantly correlated with crude protein (CP) levels but not with the
anti-nutritional constituents, such as tannins, indicating that these
factors did not affect local preferences. The data confirm the
reliability of local knowledge in evaluating the nutritional value of
forage species. (C) 2016 Elsevier Ltd. All rights reserved.
