The Deprim phyto preparation influence on nonspecific resistance of pigslets’ organism

The purpose of the research is to study the effectiveness of using various doses of "Deprim" preparation to piglets during the first to third months of their rearing. The herbal preparation "Deprim" contains an extract of the herb St. John's wort (Hupericum perforatum L.). To study the effect of the phytopreparation "Deprim", clinically healthy weaned piglets of a large white breed at the age of 60 days, who had dyspepsia in the newborn age, were selected according to the principle of pairs-analogues.The animals were divided into three experimental and control groups of 7 heads each (n=7), so that the average weight did not differ statistically between the groups. Objectification of the effect of the phytopreparation was performed based on the results of determining body weight gains and average daily gains, hematological and biochemical parameters of animal blood. It is shown that the use of the phytopreparation “Deprim” when feeding pigs in two courses at a dose of 5; 10 and 15 mg/kg f. m. contributed to a positive effect on the nonspecific resistance of the organism, productivity and their safety. This is evidenced by the determination of body weight gains and average daily gains, hematological and biochemical parameters of animal blood. It was found that already 10 days after giving the phytopreparation the 3rd experimental group animals' body weight significantly (p ‹ 0.01) increased by 1.06 times in comparison with the control group. After 20 days of the experiment, positive dynamics was also noted in piglets of the 3rd experimental group - a significant (p ‹ 0.05) increase of 1.08 times compared with the control group.It should be noted that a month after giving the animals a phytopreparation, its positive effect on the increase in live weight was noted in animals of all experimental groups. Thus, 60 day-old piglets of the first, second and third experimental groups proved to gain a significant increase in animal body weight in 1.04 (p ‹ 0.05), 1.10 (p ‹ 0.05) and 1.15 (p ‹ 0.001) times, respectively.
