Abstract

The aim of this study was to investigate the effects of different starch sources on endogenous nitrogen and endogenous energy losses in Rex rabbits. Thirty about 1.5-year-old Rex rabbits were selected and randomly divided into 3 groups, and each group had 10 rabbits (half male and half female). The rabbits in the 3 groups were fed corn starch type, potato starch type, and cassava starch type nitrogen-free diets, respectively. Both pretrial and formal trial periods lasted for 7 days. The result showed as follows:in the endogenous nitrogen loss respect, the metabolic fecal nitrogen (MFN) and endogenous urinary nitrogen (EUN) of Rex rabbits had no significant differences among groups (P>0.05). But in general, the endogenous nitrogen loss of cassava starch group was the highest, followed by corn starch group and potato starch group. In the endogenous energy loss respect, the fecal energy from metabolic origin products (FmE) and urinary energy from endogenous origin products (UeE) of Rex rabbits had no significant differences among groups, too (P>0.05). But in general, the endogenous energy loss of cassava starch group was the highest, followed by corn starch group and potato starch group. In conclusion, although the MFN, EUN, FmE and UeE are not significantly affected by different starch sources, the cassava starch group as a whole has higher endogenous nitrogen and endogenous energy losses than the corn starch group and potato starch group.
