Abstract 

A total of 40 male growing rabbits were equally divided into 2 main groups of 20 each to be fed on either of the two basal diets: water spinach (Ipomoea aquatica) or sweet potato vines (Ipomoea batatas). Each of the two main groups were divided into 5 sub-groups (treatments) of 4 rabbits each to receive one of 5 graded levels of paddy rice, which were 0, 1, 2, 3 and 4% of live weight (LW). Level of paddy rice had no effect on total DM intake, reduced digestibility but improved feed conversion and LW gain. Compared to sweet potato vines, water spinach was more digestible and supported better feed conversion than sweet potato vines. Under most circumstances the improvement in growth performance due to paddy rice supplementation is unlikely to be economical, when high quality forages such as water spinach and sweet potato vines are the basis of the diet.
