The Effect of Harvest Time and Dry Methods on the Crude Protein and Crude Fibre of the Alfafa (Medicago sativa) Hay

SUN Jing kui (Forage and Feeds Station, Animal Husbandry Center of Dingxi County, Dingxi, Gansu, 743000)  
The results from variance analysis on the crude protein and crude fibre contents of alfafa hay show that the alfafa hay harvested at the beginning of blooming possess higher crude protein content (p0.01) and yield than those harvested at the luxuriantly blooming. The crude protein of alfafa dried on the shelf is higher than that dried in small bundles or tedded in thin layers (p0.05), the crude protein in the alfafa can be promoted by 0.82% and 1.91% respectively, although the crude fibre in the alfafa can be significantly lowered (p0.05), the decrement are 0.91% and 1.61%. Therefore, the high quality and yield alfafa hay can be obtained when it is harvested at the beginning of blooming under the fine weather and it is dried on the shelf.
