This review scans through the attributes of feed resources prevalent in the
arid and semi-arid zones (ASAZ). The merits of the various biological and
chemical attributes of feeds are discussed with a view to suggest those tha
t could yield suitable and reliable indices for selecting potential feedstu
ffs among forage legumes. The review contends that besides protein content.
the rate of degradation and bulk density are two other legume factors that
determine the extent of substitution of the basal roughage diet which will
vary in direct proportion with roughage quality. The appropriate combinati
ons of roughage and supplements have been advocated for sustainable livesto
ck production in the ASAZ Whilst most legumes contain more protein than is
required to balance the fermentable energy in them and thus are suitable as
supplements, their ability to supply both rumen degradable protein and esc
ape protein is varied. The review argues that the slow uptake of supplement
ation strategies among others is due to unsurmountable logistics which can
be eased by creating feed or protein banks. In relation to Issues on feed a
vailability the authors suggest that the use of feed resource on a regional
scale could be maximized by (1) integrating weather information and satell
ite images to forecast feed distribution patterns and (2) encouraging the e
stablishment of communal silage pits. Pertinent researchable issues were hi
ghlighted.
