The most common form of IBR was respiratory, which was registered in 41.7% of farms. The effectiveness of the introduced vaccine prophylaxis of pneumoenteritis in a cattle economy unfavorable for leukemia decreased by 40-70% against the background of a decrease in the level of seromucoids and an increase in the concentration of globulins. It was determined that the MPC of cerium oxide for LEС cell culture is 0.057 μg/cm3, and the CC50 of the compound is 0.077 μg/cm3. When CeO2 is introduced with the BVDV, the manifestation of virus-induced CPD is inhibited (IC50 0.036 μg/cm3) and the titer of infectious activity of the pathogen is reduced. The most effective strategy for combating IBR and BVDV in cattle is the removal of infected animals from the herd (including PI calves). Instead, the most cost-effective control strategy in highly infected herds is the use of marker vaccines, followed by differentiation of vaccinated from infected animals. A system for the control of viral pneumoenteritis of cattle has been developed, presented in the form of "Methodological recommendations for the control of viral diseases of cattle with respiratory manifestations" Product Description popup.authors Borodai Nataliia I Golovko Valerii O.
