Abstract CP violation in partial-decay-rate asymmetries are examined for some two-body baryonic decays of $$B_d^0 - \bar B_d^0 $$ system. We discuss two feasible experimental circumstances: the symmetrice + e − collisions (i) on theZ 0 resonance to produce incoherent $$B_d^0 \bar B_d^0 $$ states, and (ii) just above the ϒ(4S) resonance to produceC=even $$B_d^0 \bar B_d^0 $$ states. Using the quark-diagram scheme, we estimate the branching ratios of those decays, and the numbers ofb $$\bar b$$ pairs needed for testing theCP-violating effects for 3σ signature. We find that the promising channels may beB d 0 , $$\bar B_d^0 \to p\bar p$$ , $$\Delta ^ + \bar \Delta ^ - $$ , $$p\bar \Delta ^ - $$ , $$\Delta ^ + \bar p$$ , $$n\bar n$$ , $$\Delta ^0 \bar \Delta ^0 $$ , $$n\bar \Delta ^0 $$ , $$\Delta ^0 \bar n$$ , $$\Sigma _c^ + \bar \Sigma _c^ - $$ , $$\Lambda _c^ + \bar \Lambda _c^ - $$ , $$\Sigma _c^ + \bar \Lambda _c^ - $$ , $$\Lambda _c^ + \bar \Sigma _c^ - $$ , $$\Sigma _c^0 \bar \Sigma _c^0 $$ , $$\Xi _c^0 \bar \Xi _c^0 $$ , which should be interesting for experimental observation.
