| Abstract |
Twenty seven of weaning New Zealand White (NZW) rabbits of seven weeks of age was randomly distributed into nine groups of equal number (three rabbits in each) and similar average live body weight (813g±0.01). Each group at 7, 9, 11 and 13 weeks of age was tended to determine Ca, and P concentration in blood plasma. At 13 weeks old blood samples were collected from the ear vein of the three rabbits in each group after overnight fasting during the last day of all growth trials. A representative part (5cm) from the small intestine was dissected immediately after slaughtering of rabbits to determine Ca and P absorption rates.
The experimental groups were fed randomly on one of the nine formulated experimental rations used. The 1st ration (R1) was used as a control, which contained 10 % yellow corn + 10 % barley + 13.7 % soybean meal (SBM) +20 % wheat bran +40 % clover hay + 3 % molasses + 1 % dicalcium phosphate + 1.2 % limestone + 0.5 % sodium chloride + 0.4 % premix + 0.2 % methionine and substituting the equal parts of barley and SBM by 10 % and 20 % distiller's dried grains with solubles (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 0.5 % sea weed of the total mixed ration for ration 4 (R4) ration 5 (R5) and ration 6 (R6). The second level was 1.0 % seaweed of the total mixed ration for ration 7 (R7), ration 8 (R8) and ration 9 (R9). All rations were in pelleted form and nearly isonitrogenous and isocaloric.
The results of the present study revealed that Ca intake was increased (P < 0.05) with feeding DDGS on R8 (1.92 g/h/d) than the other rations. while feeding on R2, R7 and R9 decreased (P < 0.05) Ca intake (1.67, 1.76 and 1.07 g/h/d, respectively) at 12 to 13 weeks of age Phosphorous intake was increased (P < 0.05) with feeding on R3, R5, R6 and R8 (0.96, 0.94, 0.95 and 0.96 g/h/d, respectively). The mean values from 7 to 13 weeks old ranged from 0.61 to 0.71 g/h/d of the experimental rations. There was no significant effect with feeding on DDGS with or without SW on Ca and P absorption and concentration in blood plasma.
Urea-N concentration in blood plasma was increased (P<0.05) with feeding on R2, R3 and R7 (45.95, 45.37 and 46.53 mg/l00ml, respectively) than the other ration groups.
The feeding R9 was higher (P<0.05) in cholesterol concentration (224. 68 mg/100ml) than the other rations, while feeding on R3, R5 and R6 were higher (P<0.05) (202.22, 213.84 and 215.39 mg/100ml, respectively) than the others. Triglycerides concentration was higher (P < 0.05) with feeding R3, R5, R6, R8 and R9 (107.26, 122.02, 115.62, 119.56 and 133.58 mg/100ml, respectively) than the other rations, and total lipids was also higher with the same rations (430.0, 225.0, 267.5, 232.5 and 282.5mg/100ml, respectively).Low density lipoproteins (LDL) concentration was higher (P < 0.05) with feeding on R9 (164.23 mg/100ml) than the other rations.
It could be concluded that feeding on DDGS without SW supplementation could be increased urea-N in blood plasma, triglycerides, cholesterol and total lipids in blood plasma of growing rabbits.
