Effects of Exogenous Oligosaccharides on Fecal Microflora of Dairy Goats
摘要
Abstract
The effects of different exogenous oligosaccharides on fecal microflora of dairy goats were studied in this experiment. Six Laoshan dairy goats with an average body weight of (32. 80 ± 2. 45) kg fitted with permanent rumen cannula were used, and an incomplete Latin square design was applied. Goats in experimental groups were fed a basal diet supplemented with 1% mannose-oligosaccharides (MOS group) , galactomannan-oliggosaccharides ( GMOS group) , xylo-oligosaccharides ( XOS group) , isomalto-oligosaccharides (IMO group) and fructo-oligosaccharides (FOS group) , respectively, and those in the control group ( CT group) were fed the basal diet. The experiment consisted of 4 stages with 35 d in each stage, each of which included a 14-day pre-experimental period and a 21-day experimental period. Fresh fecal sample was collected for the a-nalysis of numbers of Lactobacillus, Bifidobacteria, E. coli. and Salmonella on day 1 ,7, 14 and 21 before morning feeding. The results showed as follows; compared with the control group, number of Lactobacillus of experimental groups was increased, and the number of FOS group was significantly increased since day 7 (P < 0. 01) ; number of Bifidobacteria was also increased, and the number of FOS group was significantly increased throughout the whole experiment (P <0. 01) ; while number of E. coli were decreased, and the numbers of MOS group and FOS group were significantly increased on day 7 (P<0.01). The results indicate that improvements on fecal Lactobacillus and Bifidobacteria and inhibition on E. coli of different exogenous oligosaccharides are different, and fructo-oligosaccharides are considered to be more efficient.关键词
