The dried, crushed roots of C. longa L. were used as raw materials (country of origin Uganda). Methoxynonafluorobutane (Novec 7100), fluoroketone and nhexane were used as extractants. Method of gas-liquid chromatography with mass detection was used. The most efficient extractant for ar-tumerone and curlone, which proved to be methoxynonafluorobutane (Novec 7100). The results of the studies indicate the prospects of using freons as extracting agents for the extraction of essential oil from the roots of C. longa L. The prospect consists in a more effective extracting ability of organofluorine solvents than n-hexane to increase the yield of both, the essential oil itself and the most pharmacologically relevant root components of C. longa L. ar-tumerone and curlone.

During the experiment, systolic blood pressure (BPs), diastolic blood pressure (BPd), pulse pressure (PP), and mean blood pressure (MBP) were registered. It was established that TES mode that switched on the electrodes feeding that were fixed on the animal head at constant current (gradually increasing from 0 to 6 mA) with further switching to 75 Hz 4.0 mA square-wave pulse (impulse duration – 3.5 ms) for 30 minutes exerted corrective effect on blood pressure in dogs with pharmacologically modeled hypertension. The results of the performed tests showed that after the injection of mesatone, midodrine, and norepinephrine, the studied BP parameters elevated in all the dogs. In animals from the test groups that were injected drugs in combination with TES, the BP parameters increased insignificantly (p>0.05). In the dogs from the control groups, the increase in the BP parameters was significant in the majority of cases (p<0.05). The most significant differences between the studied parameters were observed in groups that received mesatone in combination with TES. It was revealed that after the injection of the drug and performance of TES in animals from the test group, BPs ranged within 139.7±8.8 – 146.6±8.7; BPd ranged within 78.8±6.8 – 80.0±5.0; PP – 60.0±5.8 – 67.8±5.7; MBP – 99.7±7.8 – 101.4±7.0 mmHg.

The research was carried out at the premises of the educational and scientific poultry farm of Belgorod State Agricultural University. For the experiment, 140 daily chickens were selected and four groups (peer groups) were formed: one control group and 3 experimental groups of 35 heads each. Duration of the scientific and economic experiment – 41 days. The control group received the basic diet (BD). Chickens of all the experimental groups received the basic diet from 1 to 20 days. In 21-41 days, chickens of the 1st experimental group were fed 98% BD and 2% of the dry pulp, 2nd group – 96% BD and 4% of dry pulp, while 3d experimental group – 95% BD and 5% of dry pulp. As a result of the research, it was found that the use of dry beet pulp (replacement of 4% BD) in the diets of broiler chickens has a positive impact on their productivity and the quality of meat products. When it is included in the diet, the feed costs per unit of output are reduced. By replacing the basic diet with dry pulp, the authors significantly reduce the cost of feed, which leads to an increase in profitability by 4.7%.
