Rabbit husbandry has an important role in Vietnam, particularly for the small farmers to earn their livings by
using local grasses and supplements. The objective of this experiment was to use the molasses as cheap energy
source in growing rabbit diets to improve the income of producer. Sixty growing crossbred rabbits (Local x New
Zealand White breeds) from 500 to 850g was arranged in a completely randomized block design with 5
treatments and 3 blocks of live weight, and four rabbits in an experimental unit. The treatments were molasses
(ML) supplementation to the sweet potato vine basal diets at levels of 0, 10, 20, 30 and 40 g molasses/day/
rabbit. The results indicated that the growth rate of rabbit was significantly higher for the rabbits fed ML, and the
highest values in the ML20 treatment (Pthat molasses could be used as a energy feed for growing rabbits and supplementing molasses in diets improved
economic returns at a level of 20g per rabbit per day.
