Implication

Controlled trial reveals increased body fat without improved milk yield during intravenous glucose infusion in midlactation cows, indicating gut signaling governs glucose use.

Key Points

To determine whether graded intravenous glucose infusions elicit dose-dependent improvements in lactation performance and metabolic status in midlactation dairy cows.
Infused midlactation dairy cows (n = 6) with intravenous glucose increasing daily by 1.25% of net energy for lactation (NEL) requirement compared with volume-equivalent saline control infusions.
Assessed body weight, backfat thickness, milk production, tissue glycogen, and diurnal blood metabolites at surplus glucose levels of 0%, 10%, 20%, and 30% of NEL requirement.
Glucose infusions caused a linear increase in body weight, backfat thickness, and milk protein yield, but produced no differences in daily feed intake, milk energy output, or energy-corrected milk yield.
Plasma glucose and serum insulin increased linearly with infusion rate, triggering glucosuria, hyperinsulinemia, and the development of insulin resistance at the 30% NEL dose.
Infusions linearly reduced circulating beta-hydroxybutyrate and nonesterified fatty acids while elevating glycogen reserves in liver and skeletal muscle.
