Abstract

Ninety six crossbred rabbits aged 5-7 weeks were used to evaluate the effect of forage type,
forage level, palm oil supplementation and sex on performance of weaner rabbits in a 2x2x2x2
factorial arrangement in a completely randomized design.Factors considered were forage type
(groundnut, lablab), forage level (20, 40), palm oil supplementation (without, with), and sex
(male, female). The rabbits were offered 100 g/rabbit/day feed and clean waterfor 98 days.There
was no (P>0.05) difference in weight gain, daily feed cost, feed conversion and feed cost/kg
gain between rabbits fed groundnut and lablab forage however, feeding lablab forage gave
saving/kg gain of N42.00. Rabbits fed 40% forage had significantly (P<0.05) higher feed intake
and lower weight gain than those on 20% forage. There were non-significant differences
(P>0.05) in daily feed cost, feed cost/kg gain of rabbits fed 20% and 40% forage
levels.However, rabbits fed 20% forage gave saving/kg gain of N96.68 over 40% forage meal.
Palm oil supplementation and sex had significant (P<0.05) interaction on performance of the
rabbits.Female rabbits fed diets without palm oil had significantly (P<0.05) lower weight gain
and feed intake than females fed diets with palm oil and males fed diets with or without palm
oil. However, diets without palm oil gave saving/kg gain of N23.10 over palm oil while feeding
female rabbits gave saving/kg gain of N49.59 over males. Significant (P<0.05) interaction
between forage level and type was observed in weight gain with rabbits fed 20% lablab forage
meal being better than 20% groundnut forage meal, however rabbits fed 40% groundnut forage
meal and 40% lablab forage meal were not different. Female rabbits fed 20 and 40% forage
meal had significantly (P<0.05) higher weight gain than males fed 20% forage meal. There was
significantly (P<0.05) higher total weight gain of rabbits fed 20% forage with palm oil, than
40% forage with palm oil.It was concluded that rabbits fed 20% forage gave better performance
than 40% and palm oil improved weight gain.
