| Abstract |
Twenty male rabbits with average live body weight (LBW) of 665 g and 5 months of age were divided into two similar groups in LBW and age (10 animal each). The first and second groups were supplemented daily with Active Dried yeast (ADY) (Saccharomyces cerevisiae ) to concentrate feed mixture (CFM) at the rate of 0.0 and 10.0 g ADY / kg CFM, respectively. The feeding trial was extended for 10 weeks and the digestibility trial was carried out on 5 animals from each group 2 weeks before the end of the experiment. At the end of the experiment, blood samples were taken before morning feeding from the jugular vein to estimate blood biochemical and hormonal changes.
Results indicated that apparent digestibility of DM, OM, CP, CF and Ash significantly increased by adding ADY. The TDN and DCP percentages increased significantly also due to ADY addition. Average daily gain (ADO) and feed intake improved by 12.6 and 21.2 %, respectively, when ADY was added. The levels of T3 and T4 hormones as well as liver immunity function (i.e. total proteins, albumin and globulin), serum total lipids and triglycerides concentrations increased significantly with adding ADY to the diet of growing rabbits. No significant differences were detected in urea-N, creatinine and cholesterol concentrations as well as serum SGOT and SGPT activities due to adding ADY to diets.
It can be concluded that ADY supplement is efficiently for improving growth traits of new weaned growing male rabbits without any side effects on nutritional and physiological performance
