| Abstract |
Twenty seven New Zealand White (NZW) rabbits with an average live body weight (LBW) of2.07 kg±0.062 and 12 weeks old were divided into nine similar groups (3 in each). The experimental groups were fed randomly on one of the nine formulated experimental rations used the 1st ration (Rl) was used as a control, which contained: 10 % yellow corn +[ 10 % barley + 13. 7 % soybean meal +20 % wheat bran +40 % clover hay + 3 % molasses + 1 % dicalcium phosphate + 1.2 % limestone + 0.5 % sodium chloride + 0.4 % premix + 0.2 % methionine]. The substitution was equal parts of barley and SBM by 10 % and 20 % DDGS for ration 2 (R2) and ration 3 (R3), respectively. The supplemented seaweed (SW) for these rations was at two levels. The first level was by 0.5 % seaweed of the total mixed ration for ration 4 (R4). ration 5 (R5) and ration 6 (R6). The second level was by 1.0 % seaweed of the total mixed ration for ration 7 (R7), ration 8 (R8) and ration 9 (R9). All rations were in pelleted from and nearly isonitrogenous and isocaloric.
The results of the present study revealed that the dry matter intake was increased (P < 0.05) when feeding on R8 (10 % DDGS + 1 % SW) (128.91 g/h/d) and R6 (20 % DDGS + 0.5 % SW) (126.67 g/h/d) than the other rations. The highest TDNI (g/h/d) (P < 0. 05) values were obtained in groups fed on R6 (20 % DDGS + 0.5 % SW) or R8 (10 % DDGS + 1.0 % SW) being 90.18 and 91.40, respectively. The DEI (kcal/h/d) had also,
the same trend as TDNI, but DEI increased (P < 0.05) with feeding on R3
than feeding the other experimental diets, while the lowest value was observed with feeding on R1.
The digestible crude protein intake to digestible energy (g/Mcal) value was higher (P < 0.05) with feeding in R4 (42.51) than the other rations, but feeding on R1, R5, R8 and R9 increased significantly (P < 0.05) the DCPI / DEI (g/Mcal) (41.19, 41.95, 41.01 and 41.21, respectively) than feeding on R2 or R3 or R7 (40.32, 38.38 and 39.61 g/Mcal, respectively).
The DCFI/ DEI (g/Mcal) value was higher (P < 0.05) with feeding on R3 (22.46) than the other rations, while the other rations were ranged from 15.30 to 18.92 (g/Mcal).
The DEEI/ DEI (g/Mcal) value was higher (P < 0.05) with feeding on R3 (14.28) than the other rations, but feeding on R6, R8 and R9 (13.41, 13.25 and 13.89, respectively) were higher than feeding on R1, R2, R4, R5, and R7 (6. 70,9.62,8.78, 10.86 and 7.96, respectively).
The DNFEI/ DEI (g/Mcal) values were decreased (P < 0.05) with feeding on DDGS with or without SW. The highest values were observed with feeding on Rl, R4 and R7 (155.84, 148.46 and 154.65, respectively), while the lowest values were with feeding on R3, R6 and R9 (135.06, 138.39 and 138.89, respectively).
Caecal pH varied between 5.61 and 6.28. The pH values were not significantly affected by the feeding programme. Ammonia - N concentration was increased (P<0.05) with increasing the level of supplemented SW in the rations. The mean values were (9.96, 13.06 and 17.12 mg/l00 ml) for (0.0, 0.5 and 1.0 %SW, respectively).
