Passive transfer of colostral immunoglobulins has long been accepted as imperative to
optimal calf health. Many factors, including timing of colostrum ingestion, the method and …

The newborn calf is dependent upon colostrum for disease resistance because the
separation of maternal and fetal blood supplies prevents the in utero transfer of immune …

Efficacy of passive transfer of immunity in young calves is commonly assessed using total
serum protein (STP) or serum immunoglobulin G (IgG) concentration tested within the first …

Objective—To evaluate 3 refractometers for detection of failure of passive transfer (FPT) of
immunity in calves, and assess the effect of refractometric test endpoints on sensitivity …

Background Failure of passive transfer of maternal immunity via colostrum can occur in the
bovine, and a number of blood tests have been developed to test calves for this failure. It is …

The objectives of this study were (1) to determine the differences in IgG and total protein (TP)
content of serum and plasma samples collected from the same calves;(2) to evaluate the …

Objectives To determine the prevalence of failure of transfer of passive immunity (FTPI) and
agammaglobulinaemia in calves in south‐west V ictorian dairy herds and identify associated …

Haematological and biochemical variables are most widely used medical decision making
tool. Haematological and biochemical analyses of blood are very useful to get an insight in …

Veal calves are at high risk for disease and mortality in early life. Calves face a number of
stressors before arriving at the grower, including long transport times, which may contribute …

Feeding pregnant cows rumen-protected choline (RPC) may have the potential to affect the
growth and health of offspring, but little is known about the optimal dose, or the potential …
