Myoglobinuria - This is an acute disease characterized by profound metabolic disorders, dystrophic changes and the accumulation of lactic acid and other acids in the muscles, paresis or paralysis and degenerative changes in the central nervous system, the appearance in the blood and urine of myoglobin and its decay products (myogenic autointoxication). Equine myoglobinuria is paralytic and enzootic. The first occurs sporadically, and the second is noted enzootically. The disease quickly passes from a latent course to a clinically expressed one with developed paresis and paralysis. Both forms are identical in a number of symptoms, pathological indicators, and conditionally they are combined under the general name "myoglobinuria". The disease is not well understood. It is known that paralytic myoglobinuria affects horses of a severe type, well-nourished, at the age of 5 to 8 years, although it is also noted in horses used for other purposes: sports, attractions and light work. More often the disease occurs in winter and spring. Myoglobinuria can occur as an allergic-anaphylactic process upon preliminary sensitization of certain plant foods with proteins. The disease occurs after a long rest, forced downtime or abundant one-sided feeding. The contributing cause of the disease is the finding of horses in dark and stuffy rooms. Symptoms of the disease occur at the beginning of work or a few hours after it. Cooling the animal and drafts increase the incidence of illness. |
