| Abstract | ||||
| This research aimed to evaluate the effect of supplementation Saccharomyces cerevisia (SC) yeast on growth performance and some physiological parameters in Ossimi lambs. Twenty lambs were assigned randomly to four groups of 5 animal each. Lambs of the first group (G1) were given a basal ration (control), the second group (G2); the third group (G3) and the fourth group (G4) were given SC-5g; SC-10g and SC-15g/head of yeast, respectively plus basal ration. The effect of SC yeast treatments was significant (P≤ 0.05 or P ≤ 0.01) on body weight (BW), daily gain (DG) and dressing percentage (DP) at different ages. On the other hand, the effect of supplemented SC yeast was not significant (P>0.05) on feed intake . No significant effect of SC yeast was found on rectum temperature, respiration rate and blood parameters (total protein, albumin, globulin, urea and creatinine) Highly positive correlation between SC-yeast treatments and both of body weights and dressing percentage were found, it was ranged from 0.72 to 0.86. The highest value was 0.86 between SC-yeast treatments and dressing percentage and the lowest value was 0.72 between SC-yeast treatments and body weight at 180 days of age and the other values for correlation came in between. On the other hand, there was a negative or low correlation values between SC-yeast treatments and feed intake at different ages. In Conclusion, using SC yeast proved to be a profitable natural solution to enhance growth performance of growing lambs. This may be due to its ability to help establish a good rumen microflora from that start and its proven effect on feed utilization. | ||||
