  Measurement of serum Total Protein (TP) or Immunoglobulin G (IgG) is frequently used within the dairy industry to monitor failure of passive transfer (FPT) in calves. Through such monitoring, modifications to colostrum handling and feeding techniques can be incorporated into farm practices to improve calf management. Most studies establishing cutoff values of TP or IgG for determination of FPT have been based on data primarily obtained from Holstein calves. The purpose of this study was to determine factors associated with TP and IgG serum concentration in dairy replacement calves. Factors that were studied included, breed (Holstein and Jersey), weight, age, hydration status (packed cell volume) and rectal temperature. A total of 673 calve 1 to 30 days of age were included in the study; 411 Jersey and 262 Holstein calves. Jersey calves had consistently higher TP and IgG serum concentr.. View More»
