ABSTRACT

A study involving two experiments was conducted to investigate the growth

performance of rabbits fed diets containing graded levels of cowpea hull

(CPH) and soybean hull (SBH). Thirty-two weaner rabbits of about 6 weeks

old were used for the study. In experiment1, sixteen 6-week old hybrid

(Chinchilla x New Zealand white) weaner rabbits of both sexes with initial

average weight of 730-790g were randomly divided into four groups of 4

rabbits each. The groups were randomly assigned to four treatment diets

containing 0, 10, 20 and 30% levels of cowpea hulls. Each treatment group

was replicated four times with a rabbit constituting a replicate placed in a four

–tier rabbit cages that had a total of 16 hutches per tier. In experiment two, 16

six-week old hybrid (Chinchilla x New Zealand white) weaner rabbits of both

sexes with initial average weight of 730-790g were randomly divided into four

groups of 4 rabbits each. The groups were randomly assigned to four treatment

diets containing 0, 10, 20 and 30% levels of soybean hulls. Each treatment

group was replicated four times with a rabbit constituting a replicate placed in

a four –tier rabbit cages that had a total of 16 hutches per tier. The experiments

lasted for 8 weeks during which the daily feed intake body weight gain, feed

conversion ratio, protein efficiency ratio and feed cost per kg weight gain were

determined. The haematological parameters, digestibility coefficients, carcass

vi

and organ weights were also determined. Results (experiment I) showed that

while increasing levels of CPH in the diets had no significant effect (P>0.05)

on the average daily feed intake, daily protein intake and protein efficiency

ratio, they had significant effect (P<0.05) effect on average final body weight

and average daily weight gain of rabbits. Differences between the treatments in

nutrient digestibility coefficients were significant (P<0.05). Generally,

digestibility coefficients decreased with increasing level of CPH in the diets.

The inclusion of CPH in the rabbits’ diet resulted in the reduction of the cost of

feed per kg gain. Dietary treatments did not have any adverse effect on such

haematological values as the Hb, PCV, RBC, MCH, MCHC and MCV of

rabbits. However, the WBC was observed to decrease at the 30% level of

inclusion. While dietary treatments had no significant effect (P>0.05) on organ

weights of rabbits, they had significant (P<0.05) effect on live body weight,

dressed carcass weight and dressing percentage. In experiment 2, dietary

treatments had significant effect (P>0.05) on final body weight, feed

conversion ratio, and daily protein intake. However no significant (P>0.05)

differences were observe among rabbits in daily feed intake and average daily

weight gain. The effect of treatments on nutrient digestibility coefficients were

significant (P<0.05). Both DM, CP, crude fibre, ether extract and nitrogen-free

extract digestibility coefficients were significantly (P<0.05) decreased beyond

vii

10% SBH inclusion level. The inclusion of SBH in the diets reduced

significantly the cost of feed per kg weight gain. Inclusion levels of SBH did

not have any adverse effect on such haematological values as the Hb, PCV,

RBC, MCH, MCHC and MCV of rabbits. However, the WBC was

significantly (P<0.05) decreased at the 30% SBH inclusion level. While dietary

treatments had no significant effect (P>0.05) on organ weights of rabbits, they

had significant (P<0.05) effect on live body weight, dressed carcass weight and

dressing percentage. The results obtained in the present study show that up to

10% cowpea hull and 30% soybean hull can be included in rabbits’ diet

without any deleterious effect on growth performance, haematology and

internal organs of rabbits.
