摘要
Dietary proteins can alter gut microbial diversity. However, little is known about how gut bacteria respond to dietary proteins during short-term feeding. In the present study, PCR-DGGE analysis was performed to compare changes in gut microbial composition in rat caecum after rats were fed proteins from soy, pork, beef, chicken, fish and casein (control) for 2, 7 and 14 days. On day 2, differences were observed in microbial composition between groups of red meat (pork and beef) and white meat (chicken and fish) proteins. For a certain diet group, microbial composition showed a great change with feeding time. Principle component analysis indicated that the soy protein group showed a good separation in microbial composition from the casein and meat protein groups on days 7 and 14.
