A calf's only defense comes from colostrum since no antibodies are transferred through the placenta. A calf with little or no passive transfer is much more susceptible toscours, serious illnesses and death. A calf needs IgG to keep her strong and healthy withing the first few weeks of life before she is able to form her own antibodies.
The IgGCheck Calf Passive Transfer test is a simple, calf-side lateral flow test for determining the level of passive transfer of IgG antibodies to the newborn calf. It requires a small sample of whole blood from the calf and a PortaCheck 10ul pipetter for consistent measurement. It is accurate and affordable with results in 10 minutes. It can be stored at room temperature.
