The effects of various storage/drying procedures of bovine colostrum on the absorption of bovine serum immunoglobulin (Ig) by neonatal kids was examined. Kids either suckled their dams at birth (control) or were fed warmed liquid bovine colostrum which had been either frozen/thawed, frozen/freeze dried or spray dried. After 4 d on treatment protein analysis showed Ig of bovine origin to be present in the serum of all kids fed bovine colostrum. Kid growth and health were good, and did not differ between treatments. Results suggest that the spray process will provide a dried product with the biological properties of unprocessed colostrum.
