[Effect of lactoplasmin, gamma-globulin, Filatov's swine embryo tissue preparation and hyperimmune rabbit serum on several hematologic indices and morbidity among cattle with bronchopneumonia].

Studied was the effect of lactoplasmin, gamma-globulin, a tissue preparation of swine embryos after Filatov, and a hyperimmune rabbit serum on the hemopoieis, the white blood picture, and the morbidity rate in calves with bronchopneumonia. It was found that these preparations influence favourably the white blood picture, the clotting time of blood, and the resistance of calves. With the test calves the morbidity rate was lower than in the controls. Best prophylactic effect was produced with use of tissue preparations and lactoplasmin.
