Abstract
The effect of low-intensity laser radiation on the biochemical, immune, and clinical status of hypotrophic calves has been studied. The studies were conducted in two groups (experimental and control) of 12 animals with a syndrome of symmetric malnutrition II (moderate) severity. The calves of the experimental group underwent an intravenous blood irradiation with low-intensity laser radiation in the red spectral range (wavelength 630 nm). Animals of the control group were not treated (intact). The calves were monitored for 2 months, taking into account the incidence, duration and severity of the disease, weight gain. Blood sampling for biochemical and immunological studies was performed on the 1st and 21st day of life. Treatment of animals with low-intensity laser radiation had a positive effect on their clinical condition and productivity. Compared with the control, the calves of the experimental group were ill with gastrointestinal diseases in a mild form with a shorter duration of their course, and the increase in body weight was significantly higher. Studies have established a positive effect of low-intensity laser radiation on the biochemical status, natural resistance and clinical condition of hypotrophic calves, which allows us to recommend it for the rehabilitation of young animals.
