Resumen:
In adult ruminants, most studies use rumen bacteria concentration
to assess rumen microbiology. The total number of bacteria into
the rumen is more related to bacterial concentration (bacteria per
gram) than rumen content (gram) because the rumen size is little
variable. This could be different in kid goats because the rumen
size varies according to rumen development. This study was aimed
to determine which factor, rumen content (RC) or bacterial concentration
(BC) has the best correlation with total bacteria (bacterial
concentration multiplied by rumen content) (TB). Eighteen kid
goats were fed ad libitum with goat milk and starter ration from
birth to slaughter. Kids were slaughtered between 3 to 6 weeks of
age, and rumen content were weighed and sampled for bacterial
enumeration. Aerobic and anaerobic bacteria concentrations were
quantified by most probable number method. Pearsons correlation
coefficients between BC, RC and TB were calculated. The
correlation between the RC and TB was r=0.89 (p
