Blood glucose was similar in feedlot cattle fed high
grain diets without or with probiotic including Enterococcus
plus live yeast (Beauchemin et al., 2003). Opposed to that,
Nocek et al. (2003) and Nocek and Kautz (2006) observed a
significant increase in blood glucose of lactating cows 7 d
post-partum. The GOS fed to steers did not cause any
change in blood glucose (Mwenya et al., 2005b). Similar
propionate production among treatments in the current work
can explain no change in blood glucose.
