Twenty sexually matured New Zealand white
rabbits were used to study the effect of concentrate and forage (Calopogonium
mucunoides and Panicum maximum) combination on the productive and reproductive
performance of the rabbits. The treatments comprised the following concentrate
and forage combinations (%): A = 100:0, B = 50:50, C = 25:75 and D = 0:100. The
sixteen does were randomly allotted to the four treatment diets in a Completely
randomized design. The does were housed singly, served with feed twice daily and
portable water provided ad libitum. Results showed significant (P<0.05)
differences in the final weight, body weight gain, daily feed intake, feed
conversion ratio and feed cost of the treatment diets. Final weight was 3075.0g
for does on diet A, 2943.75g for does on diet B, 2875.0g and 2887.5g for does
on diets C and D respectively. Daily feed intake was highest for does on diet D
(500.9g) and the least for does on diet A (88.32g). Diet A had the best feed
conversion ratio (0.84), followed by diets B (2.41), C (3.29) and D (6.93).
Cost of feed was highest in diet A (N2077.6) and was decreasing as the
percentage of forage in the diets increased. There were also significant
(P<0.05) differences in the litter size at birth and weaning, average litter
weight at birth and weaning. Litter size at birth and weaning were 6.75, 6.72;
7.75, 7.75; 7.25, 7.21 and 5.75, 5.69 for diets A, B, C and D respectively.
Diet B proved superior and hence recommended


Keywords: Body weight gain, feed conversion ratio, final weight, litter size at
birth, litter size at weaning.
