The invention discloses a straw processing method capable of improving digestibility rate of ruminant animals. The straw processing method comprises the following steps: 1) smashing straw to obtain straw powder; 2) adding ErCl3 solution with the mass fraction of 0.01 to 0.03% into the straw powder, evenly stirring, utilizing Co-60 gamma ray with the dosage rate of 14 to 20krad/min to radiate for 5 to 10min and drying to obtain straw feed. According to the straw processing method, straw fiber structures can be quickly damaged with a little radiation dosage under combined action of Co-60 gamma ray radiation and ErCl3, and palatability and digestibility of the straw feed are effectively improved. 本发明公开种提高反刍动物消化率的秸秆加工方法，包括以下步骤：1)将秸秆粉碎，得到秸秆粉末；2)向秸秆粉末中加入质量分数为0.01～0.03％的ErCl溶液，搅匀，采用剂量率为14～20krad/min的Co-60γ射线辐射5～10min，干燥，即得秸秆饲料。本发明采用Co-60γ射线辐射和ErCl共同作用，可在极小的辐射剂量下完成秸秆纤维结构的快速破坏，有效提高秸秆饲料的适口性和消化率。
