| Abstract | ||
| The present study was conducted to evaluate the effect of diet supplemented with different oils on growth performance carcass of growing rabbits. Total numbers of 50 weaned male growing New Zealand White rabbits, of four weeks old with an average initial body weight 455.6 g were used in this study. Rabbits were randomly distributed into five comparable groups of 10 growing rabbit. The animals were housedin cages provided with continues feeder and automatic water facilities during the experimental period, which lasted for 6 weeks. Rabbit groups were fed commercial rabbit diet without additive (control, group 1 ), with 10 g canola oil/kg diet (group 2), with 10 g rice barn oil /kg diet (group 3), with 10 g virgin olive oil /kg diet (group 4) with 10 g sunflower oil /kg diet (group 5). Growth was assessed by measuring body weight gain (BWG). At 10 weeks of age three animals from each group were slaughtered for carcass evaluation. Results showed that the effect of different diet supplemented oils on body weight gain was significant. The highest improvement in average daily gains during the study was 13.8% in Canola oil group as compared with control group followed by 11.3 %, 8.5 % and 3.9 % for Virgin olive oil, Rice barn oil and Sunflower oil respectively, as compared with control group. Treatment with different diet supplemented oils significantly increased the dressing percentage. The meat contents of vitamins E and A were enhancement by oil supplementation. Plasma cholesterol and Triglyceride were lowered significantly in oils supplemented groups as compared with control group. The differences between groups were significant in high-density-lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C). Physical meat characteristics, as moisture and ash were nearly similar for the different groups. Virgin olive oil group showed significantly (P<0.05) highest protein content followed by canola oil, rice barn oil and sunflower oil while control group had the lowest protein content. Control group showed significantly (P<0.05) highest ether extract content, however virgin olive oil had the lowest content. | ||
