Короткий опис(реферат):
The work aimed to study the influence of methifen, fenarone, and methionine on the biochemical and
morphological indicators of the piglet’s blood. We researched three-month-old large white piglets. 10
groups were formed, each with 5 animals: a control group and nine experimental groups. We established
that antioxidants promote an increase in the erythrocyte number and the Hb level to the upper limits of
physiological indicators from the 10th day of the test. On the 60th day, the erythrocyte number in the blood
of piglets fed methionine varied between 7.15 ± 0.12 – 7.30 ± 0.12 B/l. This indicator was 7.34 ± 0.10 –
7.64 ± 0.11 B/l (Р < 0.05) in the group fed fenarone, and 7.64 ± 0.14 – 7.65 ± 0.11 B/l (Р < 0.05) in animals
fed methifen. On the 90th day, the erythrocyte number was the highest in animals that were fed methifen at a
dose of 0.9 mg/kg body weight. Relative to piglets of the C group, the aforementioned indicator increased by
12.9 %. We also found a slight growth in the activity of aminotransferases in the blood serum of piglets of
the experimental groups. In addition, it was found that the studied drugs do not affect the mononuclear
system. It was indicated by the number of leukocytes, which was within the limits of physiological parameters
during the experiment and ranged from 10.0 ± 0.12 to 11.8 ± 0.6 G/l. The highest indicators of enzyme
activity, hemoglobin content, and the number of erythrocytes in the blood of animals of the experimental
groups were established on the 60th and 90th days of the trial. It manifested the best effect under methionine
feeding at a dose of 4 mg/kg body weight, fenarone – 1.20 mg/kg body weight. and metifen – 0.9 mg/kg body
weight.
