摘要:
The effects of supplementing transition dairy cows with Acremonium terricola culture (ATC) in the transition period were investigated. Ten dairy cows received a dietary supplement of 30 g/cow/d ATC from 14 d prior to their estimated calving date to 21 d postpartum, and 10 did not. The cows that receiving ATC showed greater milk production, energy-corrected milk yield, and feed efficiency, and had a lower somatic milk cell count and body mass change than the non-supplemented cows (P < 0.05). Cows that consumed ATC also had significantly higher plasma concentrations of superoxide dismutase, glutathione peroxidase, and total antioxidant capacity than the controls (P < 0.05). In addition, they had significantly higher blood glucose and lower plasma beta-hydroxybutyrate, non-esterified fatty acid, and cholesterol concentrations (P < 0.05). This study demonstrates that dietary supplementation with ATC improved production, antioxidant status, and energy balance in transition cows, with no obvious adverse effects.
