abstract:A research was carried out to study changes of crude protein concentration of dry alfafa in storage.The one factor random progamme was adopted and all experimental materials were divided into two groups each with two treatments of squeezing and no-squeezing.Every treatment has five replicates and the dry alfafa was bundled at the water content level of 25% or 20%.Indices such as dry matter,crude protein et.al. were examined and basing on the analysis of dry matter effects of water content levels and different treatments on the concentration of crude protein of dry alfafa bundled in storage were investigated.In addition the mode of changes of crude protein concentration was also studied.Results of experiment indicate that （1）bundled at the water content level of 25% the amount of lost crude protein treated by squeezing was greater than that treated by no-squeezing;for those bundled at the water content level of 20% the result was completely reversed.（2）the amount of lost crude protein for the squeezing treatment of dry alfafa bundled at the water content level of 25% was greater than that at the water content level of 20%.So does the result for the treatment of no-squeezing.
