Equol has higher biological effects than other isoflavones. However, only about 30-50% of humans possess a microbiota capable of producing equol from dietary daidzein. In recent years, interest has grown in dietary applications to improve equol production in human and other animals. In this study, lactulose was used as a potential equol-promoting prebiotic(More)
Equol, one of the intestinal microflora metabolites of daidzein, has gained much attention for having greater bioactivity than its precursor (daidzein and daidzin) and seeming to be promoted by hydrogen gas. The effects of lactulose on the equol-producing capacity and liver antioxidant status of barrows treated with daidzein were investigated in this study.(More)
UNLABELLED Equol is the end metabolite of daidzein by certain intestinal bacteria, which has stronger bioactivity comparing with daidzein. OBJECTIVE To evaluate the role of orally administrated equol-producing bacterium on increasing equol production and shifting intestinal microbiota of embracer animal. METHODS In total 60 rats with or without(More)
In China’s swine industry, copper is generally supplemented above the National Research Council (NRC) requirement (2012) because of its antimicrobial properties and the potential for growth promotion. Yet few are concerned about whether this excess supplementation is necessary. In this study, the 16S rRNA pyrosequencing was designed and used to investigate(More)
The framework and the main features of the decision-making meteorological services system (DMMS), based on component GIS technology, are first introduced. Then some key issues of GIS application to system are discussed. At last, we draw some conclusions and make sure that this system can also bring a good construction idea of the decision-making(More)
In China, antimicrobials and copper are used extensively as growth-promoting agents for piglets. This study aimed to characterize the role of in-feed copper in the emergence of copper-tolerant and antibiotic-resistant Enterococcus and Lactobacillus isolates in Chinese pig farms. Feces of the same eight piglets from four litters at 7 and 55 days old and(More)
Equol, a microbial metabolite of daidzein, has been hypothesized as clue to the effectiveness of soy and its isoflavones but only 33% - 50% of human population can excrete equol. Recently studies indicated that hydrogen gas playsan important role in equol formation. However, researches focus on this area are just started. In this paper, the corresponding(More)
To clarify the role of intestinal microbiota on skatole production and the influences of host gender, individual fecal samples were collected from female, castrated and entire male pigs at the ages of 20, 85, and 185 days. Concentrations of skatole in feces were determined by high performance liquid chromatography (HPLC), and the bacterial community in the(More)
