Abstract
The results of the experiment could be summarized as follows:-
• At the end of the experiment (16 and 18 weeks of age), the greatest body weight (p<0.5) was recorded for rabbits fed dietary 0.3% MOS followed by dietary supplemented with 0.1 and 0.2 MOS. While, the lowest body weight value recorted for control treatment.
• Daily body weight gain was enhanced (P<0.05) for rabbits fed dietary MOS during all experimental periods. The lowest values of daily body gain during experimental periods were recorded in control treatment.
• In general, there was a positive effect on feed intake as a result of addition 0.3% MOS to rabbit diet. The values of feed intake recorded significantly (p<0.05) increase as result of supplementation of MOS compred with the control diet during the entire period (8-18 weeks of age).
• Rabbits fed diet contained 0.1, 0.2 and 0.3 MOS significantly (p<0.05) improved feed effecicency than those fed on control diet. The lowest feed effecicency was calculated for un-additional diet (control).
• Rabbits fed dietary 0.3 Mannan oligosaccharides recorded the highest dressing weight (empty carcass weight, carcass weight and head weight) and dressing percent, while control treatment recorded the lowest value in the previous paramters
• Rabbit fed MOS diets at all levels improved the digestibility coefficient of nutrients compared with the control diet .
• Increasing MOS level in rabbit diets up to 0.3% improved (P<0.05) the total albumin compared with the control diet. Hence, the greatest value of albumin was recorded for rabbits fed dietary 0.2% MOS.
• Rabbits fed dietary incorporated higher level of MOS (0.3%) recorded the greatest (p<0.05) level of GPT compared with other dietary treatments.
• Rabbits fed control diet (0% MOS) recorded the lowest level of T4 compared with other dietary treatments. At the same time, the highest (p<0.05) value recorded as result of using the supplementation of 0.3% MOS followed by 0.2% and o.1% MOS.
• The greatest improvement in T3 value was recorded for rabbits fed dietary 0.3% MOS compared with other dietary treatments.
• Rabbits fed dietary incorporated the highest level of MOS (0.3%) recorded the best (P<0.05) value of PCV% in comparison with other dietary treatments.
• Rabbits fed dietary MOS at all levels increased the values of RBC’s ,WBC’s and Hb% compared with the control tretmment.
• The greatest economical efficiency and relative economical efficiency values were calculated for rabbits fed 0.1% followed by 0.3 and 0.2% MOS compared in control treatment.
