Abstract
Two experiments were conducted to evaluate the effect of feed restriction on intake of Moringa oleifera (MO) or Leucaena leucocephala (LL) and growth of rabbits. In experiment one, 45 rabbits (male and female) weighing 1.18 ± 0.15 kg were used. They were randomly distributed to three feed restriction treatments (20, 30, and 40%) with 15 rabbits each (9 females and 6 males) and they were offered M. oleifera (MO) ad libitum. In experiment two, 45 growing male rabbits weighing 0.63 ± 0.113 kg were used. They were randomly assigned to 0, 20, and 30% feed restriction diets, and they have free access to L. leucocephala (LL). Intake of MO increased (P < 0.05) conforming feed restriction increased (40.6, 52.9, and 55.2 g/day of MO for 20, 30, and 40%, respectively). Daily liveweight gain and feed conversion did not differ (P > 0.05), and economic efficiency was similar among treatments. Consumption of LL increased (P < 0.05) in rabbits under the 30% restriction treatment in comparison to that of rabbits restricted 20% (46.0 and 44.4 g/day, respectively). Total feed intake (LL + feed) was highest in 20% restricted rabbits (108.0, 100.8, and 93.2 g/day for 20, 30, and 0%, respectively). Daily liveweight gain and feed conversion were not affected by feed restriction (P > 0.05). Economic efficiency improved twice in feed-restricted rabbits (2.0 and 2.3 for 20 and 30%, respectively) in contrast to that of the control 0% group (1.1). The results suggest that rabbits restricted up to 30% and supplemented with either MO or LL did not affect growth performance and reduced feed cost.
