RELATIONSHIP OF THE CHEMICAL COMPOSITION OF COLOSTRINE WITH IMMUNOGLOBULIN STATUS OF NEWBORN CALVES
One of the reasons for the loss of newborn calves is the insufficient intake of immunoglobulins with colostrum of the cow and, as a result, the insufficient formation of passive immunity. Timely drinking colostrum within an hour after birth in an amount of 10% of body weight from clinically healthy full-age cows ensures the creation of passive immunity in newborn calves with an immunoglobulin content of 15-20 g/l in the blood, and the body's resistance is acquired until the 8-th week of life.
