Abstract

EVALUATION OF MINERAL COMPOSITION OF Anthyllis sericeaFOR GRAZING RUMINANTS IN TUNISIA

Author(s): SELMI AYET *, FERCHICHI ALI

Objective:The study was aimed to dertemine the mineral nutritive potentiel of Anthyllis sericea in arid pasture in the south of Tunisia. This native plant was used for cattle feeding and as a helminthagogue for sheep. Method:An  experiment,  using  wet  nitric  Acid  (HNO  3)  digestion  followed  by  an  atomic  absorption  spectroscopy  (AAS),  was  carried  out  to  mesure  the  levels  of mineral elements in the leaves of Anthyllis forage. Results:the results showed that Anthyllissericea had a higher contents in Ca, K, Mg and Na necessary for the ruminants. The grazed forage had a lower content of microminerals. The forage had lower concentrations of Zn than the recommended requirements for animal nutrition. Also, the resultsof vitamin analysis showed the presence of the vitamin A, vitamin C and vitamin E in the leaves. Conclusion  :we  conclude  that  this  shurb  has  been  found  to  contain  some  nutrients  and  this  supports  its  ethno-medicinal  uses  and  therefore  makes  it  a  good  sourceof nutrients in livestock nutrition in ruminants fed on the pasture in south of Tunisia.
