Ophthalmopathology in young cattle is one of the reasons for the decline in the growth and development of calves. The cause of keratoconjunctivitis is very often a different microflora. Economic losses in keratoconjunctivitis are formed due to a slowdown in the growth and development of young animals, a decrease in productivity, and a loss of live weight. 25-30% of recovered animals remain blind, the same number lose sight by 50%. Determination of the protein spectrum and immunoglobulins in the blood of calves is of great diagnostic and prognostic value, which reflects the degree of intensity of metabolic processes and the level of nonspecific resistance of the organism. Serum proteins are components of a dynamic circulating system and reflect the physiological and biochemical characteristics of the body as a whole. They take part in tissue nutrition, the formation of immunity in infections and invasions (γ-globulin is a fraction of serum globulin, which consists mainly of immunoglobulin antibodies), maintaining pH and osmotic pressure. In ophthalmic diseases, there is a violation of the ratio of plasma protein fractions (dysproteinemia).
