Shabunin et al. (2020) [31] evaluated the effect of Biferon-B (the drug, exhibiting antiviral and immunostimulant activity, which presents a mixture of bovine recombinant a- and y-interferons with species specificity) on the prevention of mastitis in cows by intramuscular injection of Biferon- B. Biferon-B was able to increase lysozyme activity by 4.3–13.7%. The gene discussed is LYZ; the disease is mastitis.
