Dietary Energy Restriction During Late Gestation in Multiparous Holstein Cows
Multiparous Holstein cows were used to determine the effects of diet, intake, and physiological state on hepatic mitochondrial camitine palmitoyltransferase (CPT) activity. In experiment 1, 30 cows were fed high grain (HG), high fat (HF), or high grain + high fat (HGF) diets from dry-off to …
