The objective of this study was to evaluate the feed intake, growth performance and economic returns
from paddy rice (PR) and sweet potato tuber (SPT) in the sweet potato (SP) basal diets for growing rabbits. Two trials were conducted to 8 weeks (feeding trial) and 12 weeks of age (digestibility trial) rabbits using a factorial experiment. The experiment 2 factors x 4 factors) was conducted with three replications using four rabbits per experimental unit. The first factor was feed supplement with 0.43MJ/day/animal (45 g paddy rice or 115g fresh sweet potato tuber) and the second factor was the level of SP (DM basis) offered (5%, 6%, 7% and 8% of live weight (LW). During the first feeding trial to eight weeks of age rabbits, matter (DM) intake and organic matter (OM) intake was analysed. While during the second digestibility trial to twelve weeks of age rabbits, feed digestibility and nitrogen retention were determined. The result showed for the first feeding trial, the dry matter (DM) and organic matter (OM) intakes were similar between supplements and among the four levels of feed offered (5%, 6%, 7% and 8% of LW) (P>0.05). Crude protein (CP) intake was significantly higher for the paddy rice (Phigher (Psignificantly higher for the diets supplemented PR (Pfound for the diet supplemented SPT offered at 8% of LW. In the second digestibility trial, the apparent digestibility (%) of DM and OM were significantly higher in the diet supplemented PR diet (P(Pperformance, however, the SPT supplement showed a higher gross margin.
