This experiment was conducted to study the effects of ridge and furrow drying on moisture loss and the contents of crude protein (CP), ether extract (EE) and crude fiber (CF) of alfalfa green hay. A two factors (ridging×crushed) interactive experimental design was used in this experiment. Two levels of ridge and furrow drying were flat and ridging, and five levels of crushed drying were no crushed and interval crushed (interval distance was 0, 10, 15 and 20 cm, respectively). The flat and no crushed (FN) drying treatment served as control. Results showed that the moisture loss speed of alfalfa in the ridging and crushed (RC0) treatment was the fastest among all treatments (P＞0.05). After drying 10 h, moisture content in the RC0 treatment was 18.87%, and it was decreased by 19.82% compared with that in the control. CP content of alfalfa green hay in the RC0 treatment was 20.52%, which was the highest content among all treatments (P<0.05), and it was increased by 2.2% compared with that in the control. EE content of alfalfa green hay in the flat and crushed at a distance of 15 cm (FC15) treatment was 2.92%. It was the highest content among all treatments (P>0.05), and it was increased by 0.76% compared with that in the control. Using CP content served as a main quality reference factor, these results indicate that drying by RC0 can promote moisture loss and get high quality alfalfa green hay. Accordingly, ridging and crushed combination is an ideal way to drying. ［Chinese Journal of Animal Nutrition, 2011, 23（10）：1826 -1832］
