Clinical Pathology
The goat and sheep colostrum IgG concentrations
(41 and 65 mg/mL, respectively) were determined
using commercial ELISA kits (Bethyl Laboratories,
Montgomery, TX). To determine blood plasma IgG and
IgM concentrations, commercial ELISA kits (Bethyl
Laboratories) were used, with purified sheep IgG and
IgM as standard references. Results were expressed as
milligrams of immunoglobulin per milliliter of plasma.
Samples were individually analyzed in triplicate and a
valid result was considered when differences between
them were less than 10%.
