Amélioration de la valeur nutritionnelle des gousses de Piliostigma reticulatum (D. C.) Hochst dans l’alimentation du bétail en période de soudure

Dans la zone nord soudanienne du Burkina Faso, les gousses de Piliostigma reticulatum sont intensement utilisees pendant la saison seche comme aliment d’appoint pour le betail. L’objectif de cette etude est d’ameliorer la qualite nutritionnelle de ces gousses pour optimiser leur apport. Neuf rations comprenant chacune des gousses de P. reticulatum (70 p.100) et du foin de Pennisetum pedicellatum (30 p.100) distribuees a raison de 50 g MS/kg p0,75 ont ete testees sur des ovins de race Djallonke. Les gousses ont subi differents traitements physiques (concassage, mouture) suivis ou non de traitement a l’uree auxquelles est associe dans certains cas du charbon de bambou a des doses de 0,25 ou 0,50 g/kg PV dans le but d’influencer l’action des tanins. L’utilisation de l’uree a entraine, quelle que soit la forme de distribution, une amelioration de la digestibilite, surtout celle des matieres azotees en raison de l’augmentation significative de leur teneur. L’adjonction du charbon de bambou n’a ameliore la digestibilite des gousses non traitees a l’uree qu’a la dose de 0,50 g/kg PV. Par contre, sur des gousses traitees a l’uree, il a permis une amelioration significative (p<0,05) de la digestibilite a la dose de 0,25 g/kg PV.
