Influence of probiotic and yeast culture supplementation on selected biochemical and immunological parameters of growing lambs

This study was carried out to evaluate the potential effects of 90 days-long dietary supple- mentation probiotic and yeast culture on immunity condition lambs. Fifteen Rahmani growing male lambs (about 5 months old 23.21±2.75 kg body weight) were randomly allo- cated three equal groups consisting animals each. The in first group, served as a control (group C), fed basal diet without any supplementation. second third group supplemented with Y) or YC), respectively. consisted live (Saccharomyces cerevisae) alone, while composed Saccharomyces cerevisiae media which it grown. In Y YC, each lamb daily 0.5 g 7.0 culture, Blood samples collected before feeding supplements then every 15 days until day 90th. Total differential leucocytic counts, total protein, albumin, IgA, IgG IgM levels measured blood. There insignificant (p>0.05) variations counts protein among throughout experiment. However, significant differences (p⟨0.05) found globulin, both (Y) (YC) groups, but effect seems be better than that probiotic. conclusions, obtained results indicate tested improve immunological status
