Abstract: In the Sudan, rabbits are kept mainly in the backyards of houses and being reared as small-scale business. This study was conducted to investigate the nutritional potential of sweet potato vines as a new animal fodder in Sudan compared to that of conventional fodder, Clitoria ternatea and Barseem (Hijazi). Twenty seven weaner rabbits at 45 days old were used. Experimental animals were divided into three groups and fed three different rations Barseem, Sweet potato and C. ternatea for 70 days. Traits studied were final body weight, daily weight gain, daily feed intake and daily dry matter intake and feed conversion ratio. Blood traits also were studied; they include protein, globulin, albumen content, RBCS and WBCS count. The results showed significant (p>0.05) differences for daily feed intake between Clitoria ternatea and Barseem. The present study showed that, best feed conversion ratio was obtained by feeding Sweet potato to rabbit than the other rations. It was concluded that Sweet Potato meal feeding provide a good protein and energy feed for growing rabbits. For blood traits there were only significant differences for protein and globulin blood contents (p>0.05) between C. ternatea and Barseem.
