Summary: | Currently, non‐invasive animal research methods continue to develop, one of which is bioelectrical impedance analysis to determine the body's water, fat, fat‐free, and cell mass, which reflects the assessment of the body's liquids. The electrical and biological significance of impedance analysis lies in the fact that the measurement of the resistance (impedance) of the body's tissues or fluids changes during exposure to alternating currents of different frequencies and makes it possible to take into account the totality of resistance or the actual difference between two measurements taken in succession. The research object was newborn calves, healthy (G1) and with enteritis (G2), selected according to the principle of analogs, 15 animals in each group. The impedance measurements were studied using the “BICA” device (body impedance composition analyzer). Enteritis in calves is accompanied by a significant loss of electrolytes and free fluid, affecting normal metabolic processes. In this regard, the study of the liquids of the body of healthy and enteritis‐sick calves was the main goal of the research. The first signs of enteritis appeared more often on the second and third days of life. In G2: a decrease in motor activity, hunchback (calves do not lean well on the chest limbs, the head is lowered down) were shown, a decrease in the sucking reflex, retraction of the eyeballs into the orbits, low skin turgor, a red border on the gums under the arcade of the incisors. Feces in sick calves are unformed, watery, gray‐yellow in color, with a pungent, sour odor. On the tenth day of life in calves with enteritis, the total body fluid decreased, and this indicator was 1.5 times lower than in healthy calves (P |
