Effects Of Functional Oligosaccharides On Rumen Fermentation, Serum Biochemical And Immune Indices Of Goats

Six goats with an average weight (32.80±2.45) kg, fitted with ruminal cannulas, were used by a staging and grouping experimental design. The test groups were respectively fed with the diet with1%XOS, IMO, FOS, MOS and GMOS. The control group was fed with the basal diet without oligosaccharides. Effects of different functional oligosaccharides on rumen fermentation, antioxidant indices, serum biochemical indices and immune function of goats were studied in this experiment.1. The effects of functional oligosaccharides on rumen fermentation of goatsThe trial lasted for4stages. Each stage lasted for15days, preliminary trial period13days and formal trial period2days. The results showed that, compared with the control group, rumen pH decreased. It for MOS and GMOS significantly decreased(P<0.01). Ammonia nitrogen decreased. It for GMOS and FOS significantly decreased(P<0.05). Acetic acid and total VFA contents increased. GMOS significantly increased acetic acid and total VFA contents(P<0.05).2. The effects of functional oligosaccharides on antioxidant indices and serum biochemical indices of goatsThe trial lasted for4stages. Each stage lasted for35days, preliminary trial period7days and formal trial period28days.The results showed that, compared with the control, FOS could significantly decrease malonaldehyde and low density lipoprotein cholesterol in serum, increase total protein and globulin in serum(P<0.05). MOS could significantly decrease malonaldehyde and glutamic pyruvic transaminase in serum, increase globulin and phosphorus in serum(P<0.05). GMOS could significantly increase total protein, globulin, high density lipoprotein cholesterol, phosphorus in serum and total superoxide dismutase activities in serum, decrease malonaldehyde, urea nitrogen, triglyceride, low density lipoprotein cholesterol and glutamic pyruvic transaminase(P<0.05or P<0.01). While oligosaccharides had no significant difference on the glutamic oxalacetic transaminase, glutathione peroxidase, albumin, glucose, total cholesterol and calcium in serum(P>0.05). 3. The effects of functional oligosaccharides on the immune indices of goatsThe trial lasted for4stages. Each stage lasted for15d, preliminary trial period13d and formal trial period2d. The results showed that, compared with the control group,1)21d, the concentration of serum AKP in FOS group was significantly increased(P<0.05), the concentration of serum AKP and LSZ was significantly increased(P<0.05).2)21d, the concentration of serum IgA in FOS, MOS, GMOS groups was significantly increased(P<0.05or P<0.01);7d and21d, the concentration of serum IgG and IgM in FOS group was significantly increased(P<0.05or P<0.01);14d and21d, the concentration of serum IgG and IgM in GMOS group was significantly increased(P<0.05or P<0.01);7d and14d, the concentration of serum IgM in MOS group was significantly increased(P<0.01).3)7d, the concentration of serum IL-2、 IL-4and IL-6in FOS group was significantly increased(P<0.05or P<0.01);7d and21d, the concentration of serum IL-2and IL-6in GMOS group was significantly increased(P<0.05);14d, the concentration of serum IL-4in FOS and GMOS groups was significantly increased(P<0.05).
