Abstract
This study was conducted to evaluate the effect of addition of commerical baker's yeast (Saccharomyces cerevisae SC) or Iraqi probiotic (IP) locally produced, which consists of two types of bacteria and one type of yeast (Lactic acid bacteria, Bacillus subtilus, Saccharomyces cerevisiae), the bacteria Bacillus subtilus were isolate and diagnose from components of gut of common carp fish (Cyprinus carpio L.) on digestion, weight gain and some blood parameters in Awassi sheep. Nine Awassi male sheep 5-6 month of age with average body weight 30-36 kg were selected randomly and divided into three similar groups according to their body weight (3 males in each group).The experiment was lasted for 45 days. Experimental groups were as follows: first group (control) fed the basal ration without any addition. Second group fed on control ration with addition of 7.5g/head/day live dried SC and third group fed on control ration with addition of 1g/head/day Iraqi probiotics(IP). The basal ration composed of concentrates feed mixture: roughage (50:50). Results revealed that the digestibility of dry matter (DM) and crude protein (CP) was higher (P<0.05) with addition of 1g/head/day Iraqi probiotics as compared with control group. Whereas no significant difference in neutral detergent fiber (NDF) and acid detergent fiber (ADF) digestibilities among treatments. Results showed that the live body weight gain was increased with addition of SC only. No significant differences among the three groups in blood plasma parameters, but albumin concentrations was decreased (P<0.05) with SC and IP. Also the interaction between treatments and period revealed that there was significant(P<0.05) decreased in plasma cholesterol and globulin concentrations, with addition of SC and IP, and significant (P<0.05) increase in total protein concentration with addition of SC. In conclusion, addition of commercial yeast and Iraqi probiotics to ration improved dry matter and crude protein digestibilites without affecting average daily gain .
