| Abstract |
Eighty one, 7 weeks of age weaning New Zealand White (NZW) rabbits were used in this study. Rabbits were randomly distributed into 9 equal groups and housed in separate cages. The Ft experimental ration (RI) was used as a control, which contained of: 10 % yellow corn + 10 % barley + 13.7 % soybean meal (SBM) + 20 % wheat bran + 40 % clover hay + 3 % molasses + 1 % calcium diphosphate + 1.2 % limestone + 0.5 % sodium chloride + 0.4 % minerals-vitamins mixture + 0.2 % methionine . Equal parts from barley and soybean meal in Rl were substituted by 10 % or 20% distiller dried grains with soluble (DDGS) in ration 2 (R2) and ration 3 (R3), respectively. The supplemented seaweed (SW) for these rations was at tow levels subtracted from the wheat bran. The first level was 0.5 % SW of the total mixed ration for ration 4 (R4), ration 5 (R5) and ration 6 (R6). The second level was 1.0 % SW of the total mixed ration for ration 7 (R7), ration 8 (R8) and ration 9 (R9).
The experimental rations had no significant effect on live body weight (LBW) of growing rabbits from 7 to 13 weeks of age. Rabbits fed on R1 and R3 showed the highest LBW from 7 to 13 weeks of age compared with those fed the other rations. Also, rabbits fed on R6, R8 and R9 had higher LBW than those fed on R4, R5 and R7. Averages daily gain for rabbits fed 0 % SW was higher (P < 0.05) than that for rabbits fed 0.5 % SW The average changes in LBW of growing rabbits from 7 - 13 weeks of age were highest with feeding on R1 and R3 compared with that of feeding on other rations. The averages of LBTV changes were nearly similar for rabbits fed on R2, R5, R6, R7, R8 and R9 and the lowest value was observed with feeding rabbits on R4 The dressing percentages were
63.42, 62.13 and 64.01 % and the slaughter weights were 1902.22, 1990.56 and 1948.33 g with supplemented 0.0 %, 0.5 % and 1.0 % SW respectively, while the slaughter weights were 1905.56, 19995.0 and 1940.56 g with feeding on 0.0 %, 10 % and 20 % DDGS rations, respectively. The hot carcass as were the highest (1118.33 g) with supplemented 1.0 % SW rations and (1127.22 g) with feeding on 10 % DDGS rations. Experimental rations had no significant effect on averages of dry matter intake (DMI) of growing rabbits from 7 to 13 weeks of age. No significant effect was detected due to feeding experimental rations on feed conversion values of growing rabbits from 7 -13 weeks of age.
The economic efficiency (%) results showed that feeding growing rabbits on R3 recorded the highest value (313.3 %), while feeding on R 4, R5, R7 and R8 showed the lowest values being 259.2, 251.5, 244.3 and 255.2 %, respectively.
Keywords: Performance, DDGS, SW, feed utilization, economic efficiency.
