Abstract

In a 8- week study, 24 weaned New Zealand White rabbits, 5weeks old , divided into 3 groups were subjected to isoenergetic & isonitrogenous diets consisting of concentrate pellets (fed ad libitum) to, or coceltrate pellets include 10% filter cake Ti and 20% T2. Each group were caged in 5 digestibility trrial was conducted at the end of the digestibility trial to determine changes in nutrients when filter cake was added to the tested diets T1 and T2 Rabbits. Three reperesentative rabbits from each feeding treatment were chosen randomly at 13 weeks and slaughtered for studying the carcass characteristics to find out differences due to FC feeding. After 56 days of feeding, the average live weights of rabbits fed to, T1 and T2 were 2090, 2095 and 2060 g, respectively. Average daily feed intake, average daily gain and feed conversion ratio were 92.49, 86.42 and 88.47 g, 21.36,21.97 and 21.10g and 4.31,3.92 and 4.19 for the respective diets. Results indicated that supplementation of FC in the experimental diets did not adversely effect nutrients digestibility coefficients and nutritive values of the experimental diets with beneficial improvement (P<0.05) in digestibility coefficients of CF of T1 diet (10%FC) 47.98% as compared to the other experimental diets (42.31 and 42.00 for T0 and T2 respectively. The values of TDN(%) and digestible CP(%) were not affected by dietary treatment. There was no significant difference between treatments with respect to dietary treatment had no significant effect on weight of edible and inedible carcass parts and their percentages and dressing percentage in terms of carcass. Differences in dressing percentage, carcass weight and offal traits were not significant affected by dietary treatment (head, liver and kidney ) weight was lower for control than for T1 and T2. Filter cake supplementation increased total microbial and cellulose decomposers counts in the caecum content to (1.2X 108 and 4.9X102 ) and(1.9X107 and 2.3X102 CFU/g with T1 andT2 diets, respectively. conpared to the control diet, were 1.2X106 and 15CFU/g for total microbial and callulose decomposers, respectively. There were no yeast cells recorded in the rabbit caecum contents. Economical efficiency was improved by 30.55 and 28.73% for 10 and 20% FC supplementation, respectively compared with the control diet. The nutritional and economical point view, it may more appropriate in area where sugar industry are located , to raise rabbits on available forages with an energy and protein supplement based on filter cake especially where commercial feeds are either not available or cost –prohibitive, Keywords: Rabbits, filter cake, growth, feed utilization, total microbial count and Cellulose decomposers
