A study was conducted at the experimental farm and laboratory of Can tho University to evaluate feed
utilization, and growth performance of 96 crossbred rabbits (New Zealand x Local). The experiment was
arranged in a 2x4 factorial design. The first factor was feeding strategies (separate and mix) and second factor
was levels of Psophocarpus scanden (PS) supplementation (0, 25, 50 and 75%, DM basis) in Para grass as basal
diets, with three replications and 4 rabbits per experimental unit. The results indicate that values of nutrients and
ME intakes were significantly higher (Pincreased (PPsophocarpus scanden in the diets. The daily weight gain and
feed conversion ratio of the rabbits fed in separation diet and 75% PS supplementation were improved (PIt was concluded that separated feeding and 75% Psophocarpus scanden supplementation had better growth rate
and gave higher economic return.
