Effects of colostrum-conferred passive immunity on disease incidence in Korean native calves during the suckling period
1989
Kim, D. | Han, H.R. (Seoul National Univ., Suwon (Korea R.). Coll. of Veterinary Medicine)
The effects of the serum total protein and immunoglobulin levels of the colostrum-conferred Korean native calves at 2 days of age on the disease incidence during the suckling period were studied. Serum total protein, total immunoglobulin, IgG, and IgM levels of 6 Korean native calves died from septicemia were lower than those of calves survived (p0.05). Korean native calves having low serum total protein and immunoglobulins were affected with diarrhea earlier in life, when compared with calves having high serum levels (P0.05). Korea native calves having low serum total protein were affected with bronchopneumonia earlier in life, when compared with calves having high serum levels (P0.05). Korean native calves having low serum neutralizing antibody titers to bovine viral diarrhea virus had high incidence rate of BVD, when compared with calves having having high serum neutralizing antibody titers (P0.05)
