摘要: Abstract INTELLIGENT use of new sources vitamin B12 in feeds requires reasonably accurate methods assay. Methods obtaining a value feedstuffs with chick assay have been described by Bird, Rubin and Groschke (1948), Lillie, Denton Bird (1949), Coates, Harrison Kon (1950), Ott (1951). The rat has employed to estimate the content Hartman, Dryden Cary Lewis, Register Elvehjem Register, Thompson (1949). Ansbacher et al. Peeler, Yacowitz Norris Peeler (1941), DeHeus DeMan (1951), Tarr (1952) microbiological assays feedstuffs. Stokstad, Hoffman Jukes (1949) were unable obtain agreement values estimated animal bioassays. Cheng Thomas (1951) reported that re-sults bioassays kidneys laboratory …
