Abstract
A total of 64 New Zealand and Californian rabbit were caged individually to study the nutritive value of 4 protein sources for growing rabbits. Rabbit fed fish meal and chicken offal as principal protein sources in the diet consumed more and grew significantly (P<0.01) faster (30.1 and 26.7 d/day) than those fed plant proteins of cassava leaf and cotton seed meals (25.0 and 22.3 g/day). Carcass yields of 54 % for rabbits fed fish meal diets, 52.3 % for those fed diets with cassava leaf meal, were similar but significantly (P<0.05) higher than 49.92 % for rabbits fed cotton seed based diets. Calculated meat costs per kilogram based on feed costs only, showed the most efficient diet to be that containing chicken offal meal followed by that containing cotton seed meal, then cassava meal. The most inefficient diet cost-wise, was the diet containing fish meal.
