BOVINE CORONAVIRUS-ESCHERICHIA COLI ANTIBODY (BOVINE ORIGIN)
Calf scours (diarrhea) is one of the most common and costly diseases in calves, resulting from lack of sufficient protection from colostrum. The first 12 hours of a calf's life are critical for antibody absorption. ImmuCell continues to be on the forefront of scours prevention technology, manufacturing and selling First Defense®, the most popular and convenient scours preventive administered to calves.
Prepared from hyperimmune bovine colostrum, First Defense® is a bolus which dissolves readily upon reaching the calf's stomach, providing protective levels of antibodies to potential sites of intestinal infection. These highly specific antibodies serve to block enterotoxigenic E. coli adherence and interfere with coronavirus infection of intestinal epithelial cells, thereby reducing scours related morbidity and mortality. First Defense® delivers preformed immunity and immediate protection when calves need it most. Maximal protection is achieved when administered in the first 12 hours after birth and used in conjunction with good colostrum feeding and calf nutrition programs.
Quick and easy to administer. Do not vaccinate calves with oral coronavirus products within 5 days of administration of First Defense.
