Rabbit production in Cameroon like other countries in the Central African Region is timid and is partly caused by inadequate knowledge of feed ingredients as well as feeding and other management techniques. This study evaluates the effect of partial substitution of sun-dried brewer’s grain (SDBG) with palm kernel cake (PKC) on the growth performance and digestibility in weaner rabbits. The substitution levels were: 0% SDBG, 25% SDBG, 50% SDBG and 75% SDBG respectively representing T1, T2, T3 and T4. Twenty weaner rabbits (Oryctolagus cuniculus) were used for the study. After balancing for weight, the animals were randomly and equally assigned to four dietary treatments. Each dietary treatment had five rabbits. The rabbits for each treatment were housed together. The animals were fed for 9 weeks on the test diets and supplemented with potato (Ipomea balatas) vines. The test diets and water were given ad libitum. During the seventh week, faecal samples were collected for three days and sun-dried. AOAC 1990 version was used for the proximate analyses while SPSS was used for the statistical analysis. Nutrient digestibility was calculated using percentage nutrient in the ingredients and the results from proximate analyses of the diets and faecal samples. No mortality was recorded. Feed intake, feed conversion ratio and cost of the diets increased with increase levels of SDBG but weight gain, growth rate and feed efficiency were the reverse. There was a significant difference (P<0.05) in feed intake, weight gain, daily growth rate, feed conversion ratio and feed efficiency between the different treatments. Excluding the control (T1), T2 (25% SDBG and 75 % PKC) showed the best performance and the highest TDN (6.99%). The results indicate that SDBG meal could replace 25% of PKC meal in the diet of weaner rabbits.
