Anti-fatigue Effect of Fresh Donkey Milk

Objective: To investigate whether fresh donkey milk alleviates swimming exercise fatigue in mice. Methods: ICR mice were randomly divided into 4 groups (n = 12), which were administered with fresh donkey milk at low, middle and high dosages (5, 10 mL/ kg and 20 mL/ kg) once a day for consecutively 30 days and saline as (control), respectively. According to Technical Standards for Testing Assessment of Health Food (2003 Edition), mouse exhaustive swimming time, serum urea level, blood lactate content and hepatic glycogen content were determined. Results: Compared with the control group, the swimming time, serum urea level, lactate content in blood and hepatic glycogen content in mice administered with fresh donkey milk at high dosage exhibited a significant enhancement (P 0.05 - 0.01). Conclusion: Fresh donkey milk has an obvious anti-fatigue effect.
