Abstract

Experimental studies were carried out on rams at the age of 2.5 months. Animals were formed into 2 groups: control and experimental, each with 5 animals weighing 20.0±1.0 kg. The compound feed was treated with the prepared preparation before feeding at a dosage of 0.02 mg/kg of live weight of the rams of the experimental group, once every 7 days, 4 times during the entire study period. The duration of the experiment was 30 days. These results were especially evident on the 30th day of the experiment in terms of the number of erythrocytes, which in the experimental group of animals increased by 6.5 % during the study period. The content of hemoglobin increased by 6.6 %, and the hematocrit value increased by 2.3 % compared with the control. The indicators of the protein component of the blood plasma also changed. The total protein over the period of research in the experimental group increased by 6.05 %, while in the control group it increased by 2.56 %, i.e. 2.3 times. The amount of albumins in the experimental group increased by 9.7 %, and in the control group by 7.67 %, i.e. 1.2 times. The content of globulins in the experiment increased by 3.2 %, in the control by 1.45 %.
