摘要

The objective of this experiment was to determine whether there is a dose of slow-release insulin (SRI) that decreases concentrations of plasma nonesterified fatty acids (NEFA) and liver triglyceride (TG) without decreasing plasma glucose concentration, dry matter intake (DMI), and milk yield. Forty-three Holsteins weighting 765+70 kg with body condition score of 3.29 ± 0.25 (mean ±SD) were fed for ad libitum consumption of the same diet from 2 wk before parturition through 6 d postpartum. Cows were blocked according to actual calving date and parity and then assigned randomly to intramuscular injection of single dose of 0, 0.14, 0.29, 0r 0.43 IU of SRI per kilogram of body weight (BW) on d 3 postpartum.
