Testing for failure of passive transfer: are all tests made equal?

Autor: WA Mason, Richard Laven, EL Cuttance

Publikováno v: Livestock. 22:244-247

Testing for failure of passive transfer (FPT) is common practice, yet there is still confusion around the best tests to use. Worldwide, the most common tests used are IgG concentration, total protein (TP) concentration (measured in a laboratory or on
