Different Exogenous Oligosaccharides Affect Serum Biochemical Indices and Antioxidant Indices of Dairy Goats
摘要
Abstract
Effects of different exogenous oligosaccharides on serum biochemical indices and antioxidant indices of dairy goats were studied in this experiment. Six healthy dairy goats with an average body weight of (32.80 ± 2. 45) kg and similar age were used in a staging and grouping experimental design. Goats in the experimental groups were fed diets supplemented with 1 % mannan oligosaccharides (MOS) , galactomannan oligosaccharides ( GMOS) , fructooligosccharide (FOS) , xylooligosaccharide (XOS) and isomalt oligosaccharides (IMO) , respectively. The goat in the control group was fed a basal diet without oligosaccharides. The trial consisted of 4 stages. Each stage lasted for 35 days (7-day pretrial period and 28-day trial period). The results showed that compared with the control group, FOS significantly decreased the contents of malonalde-hyde (MDA) and low density lipoprotein cholesterol (LDL-C) in serum (P <0. 05), and significantly increased the contents of total protein (TP) and globulin (GLB) in serum (P <0. 05) ; MQS significantly decreased MDA content and glutamic pyruvic transaminase (GPT) activity in serum (P <0. 05) , and increased the contents of GLB and phosphorus in serum (P <0. 05) ; GMOS significantly increased the contents of TP (P < 0. 05) , GLB (P < 0. 01) , high density lipoprotein cholesterol (P < 0.05) , phosphorus (P < 0.05) and total superoxide dismutase activity in serum (P <0. 05) , and decreased the contents of MDA (P<0.01), u-rea nitrogen (P<0.05) , triglyceride (P<0.05) , LDL-C (P<0.05) and GPT activity (P<0.05) , while oligosaccharides had no significant effects on the activities of glutamic oxalacetic transaminase, glutathione per-oxidase, and the contents of albumin, glucose, total cholesterol and calcium in serum (P >0. 05). In conclusion , oligosaccharides can enhance the antioxidant ability to a certain extent, improve lipid and protein metabolism, promote the absorption of calcium and phosphorus, and have no liver and heart damage in dairy goats. Therefore, it is suggested that FOS, MOS, GMOS can be used to supplement diets for dairy goats, and the GMOS is preferred. [ Chinese Journal of Animal Nutrition, 2012, 24 (2) : 342 -348 ]关键词
