【Abstract】 The effects of mannanoligosaccharide (MOS) and streptococcus faecium cernelle 68 (SF 68) in diet for chicken on cell mediated immunity, intestinal parameters and SOD, GSH Px in blood were reported. 60 one day old male chickens of Hy line were divided randomly into 4 groups: group one (basic diet containing 0.2% MOS), group two (basic diet containing 60×10 -6 SF 68), group three (basic diet containing 0.2% MOS and 60×10 -6 SF 68) and control (basic diet). All chickens were slaughtered in 42 days old. The results showed that (1) PHA lymphoblast transformation rate in group one (47 1±3 071), group two (46 7±1 767) and group three (48 3±2 312) is great significantly higher than that in control (43 8±1 814)(P<0 01);(2) macrophage activity in group one (25 3±1 947) and group two (25 3±2 541) is significantly higher than that in control (23 6±1 647)(P<0 05); macrophage activity in group three (27.7±1.889) is significantly higher than that in control (P<0.05), and significantly higher than that in both group one and two (P<0 01); (3) pH in ceca and ileum of group one (6 253±0 294,5 258±0 453), group two (6 021±0 418,5 132±0 37) and group three (6 124±0 241,5 011±0 111) is greatly significantly lower than that of control (6 667±0 212,6 08±0 412)(P<0 01);(4) E.coli in ceca of group one (9 164×10 8) is great significantly lower than that of control (9 412×10 8)(P<0 05);E.coli in ceca of group two (8 748×10 8) and group three (8 726×10 8) are great significantly lower than that of control (P<0 01) and group one (P<0 01); (5) SOD and GSH Px in blood of group one (9 446±0 56,7 541 6±370 01), and group two (9 42±1 005,7 412.1±482 08) are significantly higher than those of control (8 446±0 292,7 064 7±391 03) (P<0 01),SOD and GSH Px in blood of group three (9 789±1 012,7 655 5±266 17) are great significantly higher than those of control (P<0 01). It can be concluded that cell mediated immunity, SOD, GSH Px in blood are stimulated or enhanced and E.coli counts of ceca and pH of ceca and ileum are reduced by improvement of intestinal microflora of chickens with MOS and SF 68 treatment in separation or combination. But macrophage activity and SOD, GSH Px in blood are great effectively higher in the combination of MOS and SF 68 than in other treatments.更多还原
