Abstract
A turbidimetric assay method applicable to virginiamycin at level ranging from 5 g/ton in feeds to 50% in a premix is described. Incubation period is 4 h. Test organism is Streptococcus faecium ATCC 8043. On 6 levels of feed-grade material, the overall mean recovery was 6.75% Standard recovery studies resulted in RSD values ranging from 2.01 to 3.88% and a mean standard recovery of 100%.
摘要
本文描述了一种比浊法测定方法，该方法适用于测定饲料中含量为5克/吨至预混料中含量为50%的维吉尼亚霉素。培养时间为4小时。测试微生物为粪肠球菌ATCC 8043。在6个饲料级材料水平上，总体平均回收率为6.75%。标准回收率研究得出的相对标准偏差值在2.01%至3.88%之间，平均标准回收率为100%。
