A treatment effect was detected for serum glucose
(Po0.01), NEFA (P¼0.01), and RQUICKI (Po0.01). Cows
receiving BST had greater mean glucose and NEFA concentrations
during the experiment compared with control
cohorts (Table 1). Based on serum glucose, insulin, and
NEFA concentrations obtained prior to concentrate feeding,
cows receiving BST had reduced RQUICKI, which
means reduced pre-prandial insulin sensitivity, compared
with control cohorts (Table 1).
