| Abstract | ||
| It is known that volatile fatty acids can inhibit growth of species of the family Enterobacteriaceae in vitro. However these volatile fatty acids affect bacterial population in the rumen of goats is unknown. Therefore, a study was conducted to investigate if changes in volatile fatty acids in rumen of goats during growth affect bacterial population. Results showed that members of Enterobacteriaceae and enterococci are present in large numbers in 3 weeks old kids and start to decrease when kids grow older. Lactobacilli are present in large number as well in 3 weeks old kids, but they remain stable during the growth of kids. Acetate, butyrate and propionate increase from undetectable levels in one week old kids to high concentration in 15 weeks old goats after which they stabilize. Significant negative correlation could be calculated between numbers of Enterobacteriaceae and concentration of undissociated a acetate, propionate and butyrate. It is concluded that volatile fatty acids are responsible for the reduction in numbers of Enterobacteriaceae in the rumen of goats during growth. | ||
