Kansas Agricultural Experiment Station Research Reports
Immunoglobulin G1 (IgG1) serum concentrations are used to evaluate passive transfer of immunity in neonatal calves. Total serum proteins also can be measured to evaluate calf health. If IgG1 and total serum protein concentrations change with age, it becomes imperative to compare samples only from a narrow time period. Otherwise, differences might be due to age and not immune status. To help define this time period, blood was drawn from 10 beef calves when they were 1, 5, and 10 days of age. Serum samples were analyzed for IgG1 and total protein concentrations. Total protein concentrations decreased from days 1 …
