A total of forty (40) growing
rabbits with an average initial weight of 921.5g were randomly allotted
to five dietary treatments containing 0, 10, 20, 30 and 40% palm kernel
cake as replacement for soyabean cake respectively. All diets were formulated
to be isonitrogenous (20% CP). The final live weights of the rabbits
were higher in the control diet compared to those on palm kernel cake
diets. With the exception of the rabbits placed on 40% level of palm
kernel cake daily feed intake, daily weight gain and feed efficiency
values compared favourably with those on control diet. Carcass weight
and weight of primal cuts expressed as percentage of carcass weight
did not show any significant difference between the treatment means.
Animals on 40% palm kernel cake diets had the highest (P< 0.05) cost
per kg gain compared to those on other dietary treatments. It was concluded
that palm kernel cake can be used up to 30% level in a maize – soyabean
meal based diet for grower rabbits without adverse effect on the performance
of the animals.
