摘　　要：试验对畜禽用凝结芽孢杆菌的菌剂制备工艺进行了研究,结果表明:最适吸附载体为麦麸,发酵液经离心吸附菌体损失率较高,最适干燥方式为40℃恒温干燥,制剂生产过程中粉碎时间应严格控制在15 s内,在当前益生菌和抗生素联用的客观背景下,建议和金霉素联合使用,紫外吸收剂2(3,5-二叔丁基-2-羟苯基)-5氯苯并三唑对凝结芽孢杆菌制剂在紫外环境下保护作用最佳。The article has done researches on agents prepared techology about bacillus coagulan strain applied to animal.The results showed that optinmm adsorbent carrier was wheat bran. The loss rate of living bacteria was high by absorption after centrifugation, optimum drying method was constant temper-ature 40 ℃, the time pulverized was controlled strictly within 15 s on the agent production process. In the objective causes of union application between probiotics and antibiotics, it was to be advised to use together with aureomycin, the protective effects of ultraviolet absorber 2-（3,5-Di-tert-butyl-2-hydrox- yphenyl）-5-chlorobenzotr iazole on bacillus coagulan agent at ultraviolet ray were best.
