摘要
To optimize the production process of occidium vaccine and provide the basis and methods for the production of live vaccine,this experiment uses the collected liquid with different centrifugal forces and centrifugation time,to measure and compare the recovery,purity,collection time and costs of coccidian oocyst,for the purpose of exploring the impact of washing conditions on coccidian oocyst collection in chicken manure.The results show that for the centrifugal machine with the radius of 17.2 cm,the best washing centrifugal rotational speed is 2500 rpm /min,that is,the best washing centrifugal force RCF = 1201.85 g,and the centrifugation time is 12 min.
